Intel Haswell CPUs Debut, Put To the Test
jjslash writes "Intel's Haswell architecture is finally available in the flagship Core i7-4770K and Core i7-4950HQ processors. This is a very volatile time for Intel. In an ARM-less vacuum, Intel's Haswell architecture would likely be the most amazing thing to happen to the tech industry in years. Haswell mobile processors are slated to bring about the single largest improvement in battery life in Intel history. In graphics, Haswell completely redefines the expectations for processor graphics. On the desktop however, Haswell is just a bit more efficient, but no longer much faster when going from one generation to another." Reader wesbascas puts some numbers on what "just a bit" means here: "Just as leaked copies of the chip have already shown, the i7-4770K only presents an incremental ~10% performance increase over the Ivy Bridge-based Core i7-3770K. Overclocking potential also remains in the same 4.3 GHz to 4.6 GHz ballpark."
For me, this is by far the biggest architectural improvement I see in these line of processors (check http://en.wikipedia.org/wiki/Transactional_Synchronization_Extensions and http://software.intel.com/sites/default/files/m/9/2/3/41604 for more information). If it sticks, it will help solving a lot of multi-core shared memory software development issues.
Hmm, Performance per Watt seems to have been glazed over.
The possibility of a fanless media center PC, the ability of a server farm to eliminate over half the cooling cost, and long battery life in a gaming class laptop seems to not be the attention of the article.
Gee it's only X percent faster..
The truth shall set you free!
Intel's Haswell architecture would likely be the most amazing thing to happen to the tech industry in years.
Seems I've been hearing this about each of their "tocks".... Nehalem, then Sandy Bridge, and now again with Haswell.
Their process is good, and that kind of advertising may even be warranted, but the hype is really getting repetitive.
The lack of phenomenal hardware improvements may annoy the nerds, but the mass market PC is killed by the abysmal software environment. People are fleeing to tablets and phones and with that the cloud because maintaining a PC has become just about impossible for laymen. The slowness of a desktop that hasn't seen professional maintenance is astonishing, if it is still working at all. Viruses and trojans aside, every bit of software comes with its own updater, many of which are poorly implemented resource and attention hogs. If the updater doesn't do you in, it's the bundled adware, sometimes installed by the update "service". The PC is stiff and stone cold, a host overwhelmed and killed by its parasites. Time to put it 6ft underground.
With AMDs CPU/GPU solutions?

.. for Intel. It still seems to lag behind AMD's on-die graphics.

You'll need the electricity savings to offset the absurd cost of the MacBook Air.
If it saves you $50 in electricity per month over your present system, all other factors being equal, in 3 and a half years you'll be saving money. People don't buy luxury to save money. Relevant car analogy, not a single 2013 Ferrari model gets 20 MPG or better. By contrast, most Kia vehicles get 30 MPG or better.
The moral of this story? Poor people care about economy, wealthy people care about performance, and business people look for a happy medium.
first paragraph
In the last few years, Intel has been adding new instructions that will give major performance gains when they are used. For example, Haswell can do two fused multiply-adds with four double or eight single precision operands per cycle per core, but no current code will use this. We'll get the advantage when HPC code is recompiled (in a few months time), and when general code assumes that everyone has this feature (in five years time). But on the other hand, we _now_ get the advantages of features they added five years ago.
I don't know what the OP is talking about saying it has only the same overclocking potential.
The -K series has unlocked the base clock multiplier allowing it to be set up to 166MHz without destabilizing the other controllers on the die. This should allow for considerably more fine-tuning.
Also, the theoretical maximum overclock is 8GHz (80x100MHz, 64x125MHz, or 48x166MHz). 4.6GHz may still be a reasonable goal for an air cooled system, but there is certainly more potential.
How hot do these chips get. I have to throttle my (not overclocked) 3770k when I do media encodes because it gets too damn hot. I've been meaning to get a better cooler I just haven't gotten around to it.
Intel do have the big, raw CPU power, but I think that's not something the majority of desktop users care about. AMD A10 still beats the new Intel on graphics, which is probably not key to most desktop users, but the price is: 4 out of 5 desktop users have all their CPU and GPU needs covered in the AMD A-series, at half or even one third the price of the equivalent Intel. This is the key: if you go AMD you save lots of money.
Signature intentionally left blank.
It seems the graphics for the notebook chips are pretty good: http://www.notebookcheck.net/Intel-HD-Graphics-4600.86106.0.html One step above nVidia 540m (the one I have on my laptop) http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html For reference this could play recent games on medium settings very well. For gamers that can't afford (or don't want to bother with) two computers it seems this chip will provide enough horse power to play most games, a thrown back to the era (486 dos days) where you could simply play all available pc games if your rig was not older than 2 years. These days you have to actually buy a dedicated (and expensive) gaming pc to play games, I think this is what gave the console makers the edge on the market. Intel can change that.
Intel for a little while has correctly perceived that their risk to business is from shift in computing to mobile devices and they are addressing this issue. One thing Intel has always been very good at, and I'm a great admirer of them for that, when they perceive a risk, they are extremely good at steering their giant ship very rapidly into the headwind and tackle that threat. Their process technology lead also gives them a huge advantage.
Over the next couple of years, the battle front will be the mobile and server devices, the desktop processors will become a second class citizen. Maybe this will give some lifeline to AMD, but AMD is so far behind on performance.
While I am all for advances in CPUs, I seriously wish Intel would go back to a naming scheme for its CPUs that made any kind of sense to the average buyer (or even the technically-oriented buyer). I have grown really weary of having to look at tables of CPU specifications every time I shop around for computers.
Intel's naming scheme -- expecially in recent years -- has been a mishmash of names and numbers without any obvious coherence. Get a clue Intel. You're hurting your own market.
If I didn't have to run OS X in my business, I'd buy AMD just for that reason. Their desktop CPUs may not be quite up to the latest Intel, but they are certainly adequate and the price is better.
amd also has more MB choice and more pci-e lanes.
With lntel you need Pci-e switchers on the MB to get more then 16 pci-e lanes (not counting the 4+DMI for chip set link).
I'd consider the fact that the most demanding android applications are arm specific in terms of compile is the more critical thing.
Intel does have a product with high core count, Phi has 50 cores for example.
I haven't seen a lot of evidence that ARM under load offered better price performance than Intel before. The only thing making that claim I can recall committed a grevious mistake, measuring ARM power usage and then assuming TDP value rather than measuring x86 power usage. It was undeniable that under typical smartphone/tablet conditions Intel did horribly (mostly 'idle' but immediately able to do things on demand), and that seems to have been the engineering focus this time, a shallower sleep state that's possible without screen blanking is one notable facet.
While Intel's prospects in the mobile arena are slim (Andorid has a lot of momentum, and that momentum is largely tied to ARM in much the same way as Windows is tied to x86), I suspect they will continue to rule the roost in the datacenter and workstation-like workloads.
XML is like violence. If it doesn't solve the problem, use more.
For the vast majority of even HPC code, it means compiler rework and math library development. The vast majority of benefit can be achieved with a drop in of a new library without rebuild of the application. In your example, it would be the interpreter, which actually tend to be the last things to receive this attention.
XML is like violence. If it doesn't solve the problem, use more.
For me. I couldn't care less what the majority of desktop users care about. What I care about is a CPU with high performance per watt and graphics good enough to scroll a text display (editor, eclipse) with some graphics (browser) fast enough not to be annoying, and to watch HD video without any pauses. Sandy bridge was more than good enough in the graphics department for anything I would ever want to do on current displays. Haswell will probably more than maintain this on the highest resolution displays coming down the road in the next few years.
Dollar cheapness of the CPU within limits does not impress me at all. I am generally content with a system for at least 4 years to spread out that cost, and there are many other cost centers in a system besides CPU.
I have never used a single AMD system and see no reason to believe that they will ever make anything that would change my mind.
I don't really begrudge any slack jawed gamers their massive nuclear power plant busting AMD systems with the absurd overkill of space heater SLI graphics; it's just not anything that has the slightest relevance to anything I could ever care about.
For desktop/laptop use, idle power is what matters.
It's extending battery life, not money saving.
And then there's no-poor-but-not-rich-either people who just want a system that fucking works.
Maybe he was looking at the THG test (4770K vs A10) where Intel lost on every game.
Every tech site knows Haswell has completely failed to improve over Ivybridge, but they are hiding this fact in the 'small print'. The Ivybridge and Haswell chips that Intel calls 'equivalent' show a small advantage to Haswell, but look at the power consumption of the two parts. The Haswell part uses more power than the so-called equivalent Ivybridge when running the same code, and gets a smaller performance boost over Ivybridge than its increased power usage.
Modern Intel parts do NOT run a simple constant speeds under the hood. Intel's stated base and turbo clocks are a gross simplification, and do not compare generation to generation. In other words, the Ivybridge and Haswell parts Intel states are equivalent are NOT equivalent. The Haswell part does more work at default by clocking higher on average (thus its much higher power usage under load).
At a similar power usage, Haswell seems to be somewhat slower than Ivybridge- proving another massive Intel failure in its FinFET project. Intel had attempted to redesign its transistor technology after the massive disappointment of Ivybridge FinFET performance. The truth is that FinFET concepts are under-performing horribly (for everyone) versus the early hype for this new approach to the transistor. At the same time, the vastly simpler/cheaper FD-SOI technologies are showing incredible potential at current process sizes.
FinFET has given Intel 'knee' improvements where power consumption just doesn't matter that much- namely at the low end of mains powered desktop use (or notebooks with whopping great batteries, and limited usage life per charge). On the other hand, high performance main-powered parts have got worse, and ultra-low power mobile parts have barely improved- Intel's worst nightmare.
AMD's Steamroller cores are due to catch up with Intel's cores very soon now, and AMD is going to massively out-pace Intel on RAM bandwidth (by going to GDDR5 and then a 256-bit memory interface as with the PS4). AMD is also converting to a fully unified memory architecture (already present on the PS4 APU from AMD) by the end of 2014, and will have a mostly unified part (Kaveri) at the end of 2013.
Even Intel is switching to new memory technologies with its next generation CPU, making the Haswell an expensive dead-end for ill-informed suckers. Intel is stuck between a rock and a hard-place with the coming focus on integrated graphics for both games and high performance FPU calculations. While Intel can and does improve its own dreadful integrated graphics system, it always lags massively behind AMD and Nvidia, while producing solutions that are vastly more expensive than either of its competitors.
The mobile Haswell with embedded L4 cache for the GPU is a great example of this. A mega-expensive solution from Intel with a fraction of the games performance of an equivalent solution from either Nvidia or AMD/ATI. What notebook manufacturer would be mad enough to use this part? All the expense, and none of the performance of a mid-end gaming notebook using GPUs from AMD or Nvidia.
TL;DR: Haswell is OK on the desktop, but nothing special; roughly 5%-10% better than Ivy Bridge. If you're on Sandy Bridge or better already, it's probably not worth upgrading. This architecture was designed for laptops first and foremost. Light power consumption/TDP on mobile parts, and a better GPU, are the big selling points. Apple will get much better integrated graphics so they don't need a Nvidia chip for their top rMBP, but they'll pay out the nose for it.
This is what all the rumors and leaks over the past couple months said and it's now officially confirmed.
Dollar cheapness of the CPU within limits does not impress me at all. I am generally content with a system for at least 4 years to spread out that cost, and there are many other cost centers in a system besides CPU.
It's nice to have the kind of money where you can just throw it away, but the majority of people on this planet do not have that kind of luxury.
I don't really begrudge any slack jawed gamers their massive nuclear power plant busting AMD systems with the absurd overkill of space heater SLI graphics; it's just not anything that has the slightest relevance to anything I could ever care about.
I don't really begrudge any slack-jawed gamer-haters their massive pocketbook-busting intel processors with the absurd price tag, but the fact is that the majority of users' needs are covered better by a cheap AMD chip than an expensive intel chip, because their needs include low price.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
What I care about is a CPU with high performance per watt
I have never used a single AMD system
Either you're lying or you used a P3 until mid 2006...
Why waste the silicon on a GPU that is just mediocre? Yes, you can replace a discrete video card with it, but that does not need to be 1/10th as good as this.
For some yet unknown reason the unlocked "K" Haswells (and maybe others) were so far all listed to come without TSX.
Most of the noise in my old P4 based system is from the power supply and the video card. Not that I game any more, but you need 3D acceleration to run the latest and greatest desktops under Linux.
The lower power draw of Haswell and the more-than-adequate 3D support would fit my needs just about perfectly. That 10% performance boost that the article snears at would mean the machine would only run roughly 16 times as fast as my current box.
I think I could live with that. A quiet, low-power system that just does what I need: encode and play back videos, run database software, Eclipse, and day to day browsing/email.
I do not fail; I succeed at finding out what does not work.
A MacBook Air in typical use uses 10 to 20 Watts, but let's say for the sake of discussion that it uses the full 45 Watts of its power adapter. If you left it plugged in 24x7 for a month, drawing that much electricity, you would use about 33 kilowatts, or about $0.50 in electricity. So your figure of "If it saves you $50 in electricity per month" is off by a factor of 100 to 300.
you would use about 33 kilowatts, or about $0.50 in electricity
I want your electric rates! Where I live, 33kWh costs over $4.
If I get a Haswell system and a Nvida (or AMD) graphics card will the graphics on the Haswell chip work with the card to improve performance? Or will the Haswell graphics basically be useless at that point?
Show me something comparable* to MacBook Air and I'll be more than happy to try it out.
*Price. Quality. Resale value. Longevity.
Apple have found a very interesting niche mass-producing high-end quality products. Nobody else has managed to come close quality wise and all that investment in taking a BSD kernel and sprucing it up for modern expectations has paid off quite nicely too. The cost is not absurd, in fact, for what I'm getting, I consider it surprisingly cheap.
I have never used a single AMD system and see no reason to believe that they will ever make anything that would change my mind.
So... you'd continue to buy Intel even if someone else made a better processor? A few years back, AMD did have better processors... better in both performance/price and performance/watt. I had one, and it was a great PC which I ran for 7 years or so... now I'm back with Intel. I really don't understand blind brand loyalty.
I don't really begrudge any slack jawed gamers their massive nuclear power plant busting AMD systems with the absurd overkill of space heater SLI graphics; it's just not anything that has the slightest relevance to anything I could ever care about.
High end gaming systems are almost invariably Intel based at the moment, because they are the quickest processors on the market at the moment. Low / mid gaming systems are more often AMD, because they offer as good or better performance / price. Lower end gaming systems are unlikely to run SLI configurations.
The slack jaw gamers you're spouting drivel about (all the time claiming you don't care about) don't exist.... if they do, they run Intel.
The cost is not absurd, in fact, for what I'm getting, I consider it surprisingly cheap.
That is because you are in the target demographic. A Ferrari owner feels the same way about their shiny new Ferrari, and neither the hypothetical Ferrari owner nor yourself are incorrect. For another demographic, my father, a 2003 era Windows XP machine that cost $600 and is still running today has been an outstanding value.
If all you care about are "Price. Quality. Resale value. Longevity." then a good machine is arbitrarily defined based on your opinion and relative financial status. I would personally never buy anything based on it's resale value because I do not resell things. I buy low cost, use it til it breaks, and then fix it until it's "more weld than original metal", to borrow a line from my dad. To me the word quality means I can repair it myself if it takes physical damage. From my perspective a Macbook Air is just about the least desirable laptop ever, but there again is the "target demographic". I'm not in it.
Apple makes a great product for people that like it. Ferrari make nice cars for the people that buy them. Microsoft makes a nice operating system for a lot of people, and Kia makes good economy cars for the masses. When it comes to perceptions of value, all you have to go on are opinions and biases, both personal and cultural. Windows vs Mac is like Jesus vs Muhammad. By that I mean that Linux is the only true operating system.
The match looks like it's over, but wait folks, in this exciting development Kjella has moved the goalposts right back to the single CPU heyday of 1999! He scores by moving the posts over the ball! The crowd goes ... oh wait, they've wandered off and don't care. That's it, Kjella wins but nobody cares because it's his own personal little game.
Meanwhile back in reality there are different products for different niches instead of a one size fits all device. In some areas AMD has nothing, in others Intel has nothing and pretending otherwise is utterly ridiculous.
If all you care about is the perspective of the boring desktop business app, then this processor doesn't have much to excite you. Of course, that's just one field. Sending a few database queries over the wire or updating your text boxes doesn't exactly saturate a quad-core box. Business desktop apps don't really see much no matter what.
For data-heavy, cache-intensive, and parallel-intensive programs the processor looks to offer quite a lot. HPC developers like that.
For notebooks and low-power devices the processor is wonderful. If you are paying the power bill for a data center, the energy use will add up. Accountants and laptop users will like that.
The option to have graphics integrated to the chip this way means better SOC options. Embedded developers will like that.
Many fields will see great things out of this chip.
If you are fixated on the world of desktop business software, you still get an incremental ~10% improvement. Unlike technologies such as SIMD, you get it without changing a line of code. So now you can add 10% more text boxes to fill out, or maybe pick up some more wasteful coding habits.
//TODO: Think of witty sig statement
Then you'd love mine. About $0.065/kWh in the Chicago suburbs. But that's what you get when you actually use nuclear power (55% of our power comes from nuclear reactors).
also part fo the group that wants to put DRM on software and hardware to control you
And even your rates would cost $2.15 for 33kW of electricity. The GP's 50 cents just isn't real.
A few years back, AMD did have better processors... better in both performance/price and performance/watt.
They were better on specific tasks, not consistently better. And those "cheaper" AMD cpus tend to forget to shutdown due to overheat, so it was quite easy to kill one on a 24/7 desktop operation. Besides proper 64 bit support (back when no one was using it :D), those cpus had nothing to offer except a cheaper price and a non-refundable policy. Try to return a fried processor to the supplier, and see how lucky you are.
Then, add to that the fact that most chipsets made for AMD cpus were absolute crappy. I'd go any day with an Intel mobo, instead of an AMD roulette even if it means I need to fork more money for it. Its not about loyalism, its about consistency. I use computers to make money, they're a tool. I don't care if - to buy something more reliable (even if it performs worse) I need to pay more.
Let us consider 3rd and 4th gen Intel Mobile Processors with 4 physical cores. As you can infere, we are focusing on energy efficiency for high performance mobile processors.
The TDP (Thermal Design Power) for 3rd and 4th gen
3rd gen (Ivy Bridge)
http://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture)#Mobile_processors
35 to 55 Watts
4th gen (Haswell)
http://en.wikipedia.org/wiki/Haswell_(microarchitecture)#Mobile_processors
47 to 57 Watts (probably 37 Watt versions will appear)
I cannot see the "huge energy efficiency improvement". Maybe Haswell changes from high power state to low power state faster than 3rd Gen (which is good indeed) but that does not matter to the eyes of my examination.
You'll need the electricity savings to offset the absurd cost of the MacBook Air.
Somehow nobody mentioned one of the prime bits of stupidity here: your proof of absurd pricing is a link to some random bozo on Amazon Marketplace who's listed an out-of-production 2011 model (Sandy Bridge CPU) for about $500 more than you'd pay for a brand new 2012 Air (Ivy Bridge CPU) direct from Apple's online store. (And oh by the way, speaking of Haswell, wait a few weeks and the 2013 Haswell model will probably be out.)
After clicking around a bit on amazon, it looks like they've become a terrible place to buy a new Mac. They used to stock a wide variety of new machines themselves but they're barely doing it any more. Almost everything you get when searching is used or new old stock, and most of it's being sold by non-Amazon sellers.
