AMD Launches New Mobile APU Lineup, Kabini Gets Tested
An anonymous reader writes "While everyone was glued to the Xbox One announcement, Nvidia GeForce GTX 780 launch, and Intel's pre-Haswell frenzy, it seems that AMD's launch was overlooked. On Wednesday, AMD launched its latest line of mobile APUs, codenamed Temash, Kabini, and Richland. Temash is targeted towards smaller touchscreen-based devices such as tablets and the various Windows 8 hybrid devices, and comes in dual-core A4 and A6 flavors. Kabini chips are intended for the low-end notebook market, and come in quad-core A4 and A6 models along with a dual-core E2. Richland includes quad-core A8 and A10 models, and is meant for higher-end notebooks — MSI is already on-board for the A10-5750M in their GX series of gaming notebooks. All three new APUs feature AMD HD 8000-series graphics. Tom's Hardware got a prototype notebook featuring the new quad-core A4-5000 with Radeon HD 8300 graphics, and benchmarked it versus a Pentium B960-based Acer Aspire V3 and a Core-i3-based HP Pavillion Sleekbook 15. While Kabini proves more efficient, and features more powerful graphics than the Pentium, it comes up short in CPU-heavy tasks. What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."
heterogeneous Uniform Memory Access is really what one should be paying attention to. With that tech in both of the upcoming consoles and major support from the same, Intel better watch out.

Thank's I thought it was only me that was bothered by these.
where its really shitty for amd is their reliance on lesser fabs. fully and completely, intel is way ahead of tmsc, global foundries, samsung, etc. amd's apus (recent) really hope that their acquisition of ati will pan out when software is written to utilize opencl, or similar on the gpu. but even if they do, and intel can mangle up a gpu thats half as good, intel still wins for ipc, ipw, and can ramp up the clock while staying in a thermal threshold and utilizing less power (yay haswell). i'm a big fan of AMD for some reason, and i'd like them to dump some of their money from their 2 big console contracts on 10nm "3d" fabbing. but thats many many billions of dollars, and if they dont have the pre-requisite knowledge, it'd be a hard sell to investors and a hard job to get qualified semiconductor designers. remember when IBM was the fab of choice? now its intel. and its going to take piles of cash, heaps of skill, and buttloads of tenacity to dethrone them
Where does it say that HD4000 beat Kabini in graphics tests, because I find that claim mighty hard to believe.
You guys are ridiculous.
What AMD has here is a successor to Brazos, and the primary competitor is Atom. Which it runs rings around, might I add. It also equals or beats an Ivy Bridge based Pentium in all measures except single threaded performance, partially due to Kabini not having a turbo function.
Say what you will, but AMD has a clear winner in the low cost ultra mobile market at the moment.
What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU.
Sure. Unless you're using the damn CPU at full speed.
What I'd be more interested to know though, is how expensive A4 5000 CPUs are. Do they cost as much as the Core i3 3271u?

While gaming, the 17W i3 is consuming nearly twice the amount of power as the 15W Kabini, at 35W vs 20W. Intel's ULV TDP ratings are an absolute joke.
too bad everyone else has moved to the i3
What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU.
has anyone bothered looking at the benchmarks? The overall system power consumption when games were run was 20watts for AMD and 35watts for the Core i3.
To my calculation, that's a 75% more power consumption then AMD. Intel hardly "matches" anything...
AMD was still at least 3 watts less power hungry in any other benchmark, too...

Yeah, then we can all enjoy our 1000$ i3 .
AMD will be the new favorite. Their APUs are cheap, give most bang for the buck, and are space- and power-efficient. A majority of desktop users in low- to mid-segment will find what they need in the A-series, and with the upcoming Kaveri even a few high-end users may consider ditching the expensive Intel and the big dedicated graphics board.
Are you some shill poster from Intel? Major stock holder? It's a fact that for any target performance, AMD will be cheaper, and they always give most bang for the buck. Intel only wins the very high end CPU segment - at an unproportional and ridiculously high price. So why would you claim otherwise?
There's only a small group who absolutely need the fastest CPU available. People with more money than sense, who are willing to pay an absolute extortionate price - Intel zealots. For the remaining 90%, AMD APUs will be the obvious choice.
AMD have a big part of the market covered with their new APUs, at a superior price. They even have hardcore gamers covered now that their APUs are in the XBox One and Playstation 4 because Intel's chips weren't up to the task.
Intel will be for connoisseurs.
What AMD has here is a successor to Brazos, and the primary competitor is Atom.
So AMD says, but Tom's Hardware disagrees:
So what about the Core i3-3217U, a 17 W processor? Surely that one is a more virile competitor, and not much more expensive than the Pentium. Core i3's on-die HD Graphics 4000 engine with its 16 EUs stomps all over the A4's 128 ALUs, despite the backing of AMD's capable Graphics Core Next architecture. Now, AMD claims that Kabini isn't meant to go up against Core i3. But we found notebooks with this exact CPU selling for as little as $360 on Newegg. It may turn out that the free market doesn't let AMD choose which Intel-based platforms its Kabini-based APUs contend with.
The cheapest laptop newegg sells that I could find was $250, so there's a good $100 range where Atoms, Celerons, Pentiums and AMD is battling it out - that's not much, really.
It also equals or beats an Ivy Bridge based Pentium in all measures except single threaded performance
Which is likely the part that matters in these laptops. I mean if you're trying to use these for serious number crunching you are using the wrong tool for the job. It's not like the single threaded performance is poor, it is horrible. Anandtech compared it to a i7-3517U, which is totally unfair price-wise (it's a $350 chip) but fair power-wise (it's a 17W chip). In cinebench single-threaded the Intel chip scored 1.24, the A4-5000 0.39 - that's a 3.18x performance lead with 2W higher TDP, 2.8x if you scale it to be equal. You're getting a not-quite-as-dog-slow-as-an-Atom ultra mobile laptop, but you're not getting anything fighting above it's league either.
Live today, because you never know what tomorrow brings
No, rather the AMD launch *was* the XBox One announcement
So AMD says, but Tom's Hardware disagrees:
They disagree, but they are outright lying about the power envelope comparison, even though the actual numbers are right there in the article. That's because they're lying liars who fellate intel regularly.

Uh, what? That makes less than no sense. These are budget laptops.

OK, so you said it matters, then you said it's the wrong tool for the job, which means it doesn't matter. Make up your fucking mind, if you have one and you're not just an echo of Tom's which jumped the shark (and on intel's dick) ages ago.

If you do the kind of number crunching that you just don't do on a budget laptop anyway, the kind you're complaining about, then the AMD solution still draws dramatically less power.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
It offers something in between Atom and i3. The problem is that even though it offers higher computational power it still targets the same market as Atom and it does that with less power use efficiency.
Those who trade off the computational power for battery life will mostly chose Atom and those looking for higher computational power will use celerons and i3.
They are also lying about the prices.
"But we found notebooks with this exact CPU selling for as little as $360 on Newegg."
They found one notebook, which is a $650 model, on a temporary sale for $360. The cheapest i3 notebook with the CPU they are comparing, not on sale, is $525, and it's a shitty one.
The cheapest B960 laptop is also $400, which makes it quite a bit above the $300-$350 atom models that this will be competing with. Maybe they should have compared it with the standard $300 laptop and it's shitty 1.1ghz celeron.
You missread his post. He was asserting that single threaded performance is what matters on these laptops, because no one is going to use them for big number crunching tasks that can actually use multiple cores effectively. He's correct. The Pentium beats the Brazos at single threaded performance, therefore, is a better chip for this kind of task.

Your failure to understand the argument does not constitute a failure on my part to comprehend his comment.

No, he's complextely wrong. What do you imagine that typical users need single-thread performance for? Most users need this only for games, and poorly-written ones to boot. PC games which require single-thread processing power are now vanishingly rare thanks at least in part to the influence of the tri-core Xbox 360, and the overwhelming tide of console to PC ports. Everything else the user typically does which requires very much CPU is already multithreaded. Most things the user does require virtually no CPU.
Running a GUI, editing files, I literally did these things on machines with single-digit MHz speeds which, when they were less responsive than using applications of today, were only so because of disk access times. And these tasks are today multithreaded, because they are based upon multithreaded libraries. Take a look at the programs running on a typical windows machine today, virtually all of them have a crapload of threads. Windows makes thread creation cheap in the way that Unix makes process creation cheap... not least because Windows is heavily multithreaded itself. And we are talking about what the majority of users will do with this hardware, which means running windows, playing the occasional game, watching cat videos on youtube.
Aside from games, the only times that most users use much CPU is during video encoding or possibly decoding, both of which are aggressively multithreaded and often even GPU accelerated, or while using graphics or video editing applications which are also typically heavily multithreaded, and have been for years. In short, practically no typical user actually needs serious single thread performance any more — what they need is good multithreaded performance, so that their computer can do a million pointless things behind the scenes without causing their cat videos to skip.
The Pentium beats the Brazos at single threaded performance, therefore, is a better chip for this kind of task.
The Pentium is only better than the new AMD cores we're talking about at the kind of task that people who buy APUs don't do. Thus, while your statement is factual, it is also irrelevant.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
I guess AMD drivers are not that good yet for 8000 series gpu. Better results to come in next months. Same was with previous generations and 13.x drivers multiplied fps on some games; from 0-11fps to 40 or more.
I would go one step further and say that the majority of users need neither better single-threaded performance nor better multi-threaded performance. They just need newer hardware that isn't on its last leg.
Beyond the first two or three cores, throwing additional cores at the problem provides little benefit for basic tasks. Video decoding might be multithreaded, but it is usually not massively multithreaded. At best, most of the decoding software I've worked with uses one thread to decompress and a second thread to deinterlace, so you're unlikely to use more than two cores total, in my experience, with the exception of the tiny trickle of CPU power required to fetch the data over the network or from disk in the first place.
And good app responsiveness typically requires only two cores, give or take—one to offload the minor background tasks so that they don't get backed up too far behind the foreground processing and one to handle the foreground app's processing needs. Beyond two cores, the benefits start to fall off pretty rapidly. I can perceive very little difference in responsiveness between my current-generation MacBook Pro (4-core 2.7 GHz Core i7) and my circa 2007 black MacBook (2-core 2.16 GHz Core 2 Duo) except in CPU-hungry apps like Photoshop. Once you get past four cores or so, the only benefit is for people running massively multithreaded tasks, which isn't typical end-user stuff by any stretch of the imagination.
The big difference that faster single-core performance gets you, assuming all other things are equal, is better battery life—being able to crank through the background tasks in less time means the CPU is idle longer. So more single-threaded performance per watt is a big win over more multi-threaded performance per watt because the former is more likely to result in power savings.

Uh no. I started my multicore life with an Athlon 64 X2. Then moved up to a Phenom II X3. Now I'm on a Phenom II X6. Every time I do something which requires multicore, I use all the cores. I'm not I/O limited because I have an SSD and because I use an AMD processor with a proper bus design.

First, here's zero dollars, get yourself a real OS. Second, if you were expecting to perceive the difference all the time, you don't understand how this stuff works.

Right, that would be true if the long-running tasks of today weren't multithreaded. Since they are, you benefit more from more cores than from more single-threading performance, which is what this whole fucking thread is about. Congratulations on ignoring the point. You are suffering from cognitive dissonance, and so you want to make yourself feel correct. All it requires you to do is completely miss the point.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
The Intel chips also have a big edge at audio and video encoding. But that is likely in part because of their market dominance.
Why, you ask? Encoding applications contain critical tight loops, and how well a processor performs the specific sequence of instructions can make a huge difference in speed. Those inner loops are even sometimes done as hand-tuned assembler code, one of the few places that assembler is still relevant other than embedded systems programming. Because Intel's CPUs hold most of the market, those loops are optimized to work well on them; performance on AMD systems isn't an important consideration. Inner rendering loops in games are another place where carefully tuned code gets used, and again Intel's processors are likely to get more attention.
Another factor is that the best optimizing compiler currently available for x86 code is produced by Intel. Naturally, their efforts only go into making the resulting code work better on Intel processors. Some results have suggested that their compiler deliberately produces code sequences that are especially bad for AMD's designs.
Don't forget ps4 and Xbox one are both using amd apu, that's a Hugh win for amd.
