Two Approaches to the Next-Generation Desktop
puppetman writes: "Tom's Hardware has a review up of a pre-production P4/2666 using 533 mhz Rambus memory (and shows it stomping the competition). The Pentium 4 needs memory bandwidth, and DDR doesn't supply it. Or does it? Anandtech, ironically, has a preview of the E7500 chipset from Intel - dual channel DDR with support for up to 16 gig of RAM. With a new bus architecture, this looks perfect for high-load databases that need wide pipes to hard-drives, memory, and ethernet. Both of these technologies look great for mid-range database servers.
Anandtech claims that dual DDR200 will provide 3.2 gig/second bandwidth, where Tom claims that DDR266 (single channel) offers only 2.1 gig/second. Intel is sure hedging their bets. I wonder what AMD has up their sleeves."
I am partly curious what kind of OC'ing results you will be able to get out of the 2666 MHz P4 w/ the 533 Mhz RDRAM, I would like to see it't benchmarks compared to the OC'd 2200 (to 3760 MHz) w/ slower FSB that was posted not so long ago.
Saying Java is nice because it works on all OS's is like saying that anal sex is nice because it works on all genders.
The Pentium 4 needs memory bandwidth, and DDR doesn't supply it.
Do *users* need this memory bandwidth or does the proverbial Quake benchmark need it?
Show me "desktop" (as the headline implies) application that requires this. Even the most cutting edge 3D games don't use current 3D processors to their potential, these days.

But you know there is at least one photoshop filter that would run faster on a 1ghz g4 and i'm sure we'll see steve jobs demonstrating it at macworld 2004 proving that macs are still twice as fast. :)

The vast majority of systems that are being sold today are somewhere around the 1Ghz mark. They represent the "sweet spot" on the price/performance curve, and quite frankly, users just don't need anything better. Open source OS users, such as most of us here, don't need to ratchet up the speed to 1.5Ghz unless they're running a bleeding edge release of the bloated KDE 2. Windows XP runs just great (well, as well as Windows XP can run, anyway ;) on my Duron 900.
Desktop users don't need anything faster than 1Ghz. So what's Intel's brilliant strategy? Why, they're going to develop chips that are even faster than the overpriced 2Ghz P4s they're having difficulties unloading right now.
And that, my friends, is why AMD is well on its way to winning the war. Intel is putting a product on the market without bothering to notice that nobody needs anything faster. They will lose a lot of money doing this (a friend at Intel pegged the development costs for this chip at $3.7 billion). AMD is sitting tight and refining their core business: solid, stable, speedy, and inexpensive chips that consumers can afford and that consumers actually want to buy.
If I were a stock broker, I would be telling all of my clients to short Intel and go long on AMD right about now. The revolution is underway and the underdog is winning.

Give me a desktop with no fan, lots of pixels and video RAM, and a reasonable-sized disk and a CD-burner. In a small case. And put the disk in one of those removable-drive drawers so it's easy to replace. If it needs more than 500 MHz, it belongs on the server in the back room. Desktops are for running X (or VNC if you don't have a real OS), and doing light development, and running MP3s. If I need to have a dedicated machine to do development on instead of a shared environment, (which I don't), it almost certainly needs to be a slower machine to emulate a random customer.
Actually, my current desktop is a laptop running Win98. There's never enough RAM, and often not enough disk, but the 450MHz CPU is almost always fast enough.

With all of the posts saying that our 1GHz's are fast enough, I say until Quake n looks like Final Fantasy (the movie!) we don't have fast enough CPU,RAM,Video,[Insert Bottleneck Here].

Of course a not-yet-released equivalent of an overclocked P4 is going to beat the competition vs. AMD's AthlonXP which is out and available NOW.
I would like to note that while the P4 did pounce the AthlonXP, take a look at the numbers (and i'm not talking about price, as I don't even want to know how much that P4 will cost!)
AthlonXP 2000+ runs at 1,666MHz at a bus which is the equivalent of 266MHz.
The P4 is running at 2666MHz (a full Gigahertz higher frequency) with a bus at the equivalent of 533MHz.
The (essentiually overclocked) Pentium 4 has a full SIXTY PERCENT CPU clockspeed advantage and a ONE HUNDRED PERCENT front side bus (FSB) advantage, yet look at its real-world performance:
MP3 encoding: 6.2% faster than the Athlon. (woop)
DivX encoding: 30% (note that the program is highly optimized, by Intel themselves, for the P4. How many programmers have an Intel engineer handy?)
Xinema 4D: 12.8%
3DMark 2001: 4.9%
Note that that Lightwave was not included--the only common test that runs faster on the P4 is the raytracing test. Guess which one Tom's Hardware used?
I just thought I'd point out that the only conclusion that you can really draw from these tests is that, as many in the hardware community know, the P4's architecture is designed for high clockspeed, with zero regard to actual real-world performance. Which matters more to you?

Depending on luminance levels, contrast, etc. the eye can perceive at much higher rates than 40Hz. Film appears "okay" at 24fps because the film itself has motion blur, and because most people are used to it (and filmakers work within it's limitations). But I work in a vision research lab where we have a 240Hz monitor (120 Hz for each eye with high-speed shutter stereo). For some things, it does matter.

How come so many people rant and rant about how clockspeed isn't everything, then they go and use the same argument in a different way to establish the "clear superiority" of the Athlon? Who cares how many Hz one is than the other? (Don't argue about consumers here, that's for another discussion...).
Sorry, but if you're going to paint it as an achievement that the Athlon performs so well 1000MHz slower than the 2.6GHz P4, then why can't the Intel fanboys paint the fact that the P4 runs at 2.6GHz as an achievement?

"Essentially overclocked" Pentium 4? It's not a new Pentium 4 chip, it's a new motherboard. Of course it's an "essentially overclocked" Pentium 4. Why add in the negative connotations?

I dunno, looking at these benchmarks I'd say the Pentium 4's architecture is damn fast. It's scaling up incredibly fast. Remember when it was first released and everybody called it a disaster?
Intel could easily release those 2.6GHz chips today, but they aren't doing it for marketing reasons. The architecture of the Pentium 4 is incredibly fast, but the management of the company is spreading out the releases over time. You can get a 2GHz today and overclock it to 2.6GHz. People are doing that all over.
The Athlon is a different design: It's very fast. The Pentium 4 is another design: It's very fast. The Athlon is cheaper, by a fair margin, especially at the highest end chips. But painting the picture that the Pentium 4 is so very much slower than the Athlon, especially with benchmarks like this, are just plain stupid.
His entire conclusion is absurd. Piece by piece:
:)
"Our detailed tests show that forthcoming P4 CPUs with 133 MHz FSB clock used in conjunction with the 845E chipset (DDR SDRAM support) will effectively be castrated."
Intel castrated it their selves. Compare its performance to VIA's P4X266 Chipset's performance and you will see that Intel crippled it to prevent it from competing with Intel's Rambus chipset. Notice that Intel is suing VIA for that chipset because it ruins the facade that RDRAM is better than DDR. Also note that Intel has refused nVidia's request for an Intel license for a DDR chipset. Intel knows that a dual channel DDR chipset would show RDRAM for what it is: A fraudulent attempt to maintain a high performance monopoly. Whatever company "causes to be sold" the most RDRAM gets to own a controlling interest in Rambus Inc. At this point, Intel is the clear winner even though Sony made a race out of it by packaging Rambus with the Playstation 2. Intel suppresses their own DDR performance to make people believe that RDRAM is the fastest stuff out there. AMD would be committing suicide by using RDRAM to capitalize on Intel's marketing hype because that would place them directly under Intel's thumb.
"This is because the Pentium 4 has a problem: the increase in clock speed (e.g. P4/2533 or P4/2666) will be rendered useless by the slow DDR SDRAM memory bus of the 845 platform".
Again, this is Intel's doing for product placement purposes as was done with the Celeron when it competed with the Pentium III and was done by Apple on the new iMac's 100fsb 800mhz G4. A 133fsb does not cost any money, it is just an easily achievable clock frequency with available current chipsets.
"And one shouldn't forget that even a dual DDR platform for P4 should be priced at a level that is similar to a Rambus system, considering that it's from Intel."
Rephrased: "And one shouldn't forget that even a dual DDR platform for P4 will be priced as high as an RDRAM system because Intel will not license the platform to nVidia and Intel KNOWS it will outperform a Rambus system, ruining 2 years of carefully crafted marketing and gamesmanship" The fact is, a dual channel DDR chipset from Intel may be available for the Pentuim 4, but only for the Xeon, a processor not available except from Intel's favored OEM Parteners, such as Dell.
Before you defend Intel remember that Craig Barrett, after AMD went from 10% market share to 40% in a year, said "the market is dropping" to justify Intel's reduced profits. Well, Intel is a bellwether stock and the market believed everything Craig said. The market did drop. We all lost our jobs. We can now say in hindsight that at least a part of the market was due to drop. But because of Craig's statement, it was the tech sector that was hit first, and hardest. Instead of simply saying, "Intel has reduced profits because of competitive pressure", he brought the entire tech sector down with him. The recession that was due could have been placed entirely on Enron's shoulders. The energy sector was in fact dropping. Enron's insiders were cashing out at the same time Craig made his statement. People got scared and pulled their money out of the market. There was less money in the market than there had been and it came out of the tech sector when it should have come out of energy.
Go ahead and defend Intel. They have made poor greedy choices, sold inferior products at exorbitant prices and done it at the expense of all our livelihoods. Shame on them.
Intel's 1.7 trillion dollar market cap has been cut by Tom Pabst on more than one occasion. A series of articles he has had deriding Rambus, causing the 1.13 Ghz recall, and showing the Pentium 4 for the paper tiger it is has seriously hurt Intel. But Tom, like all hardware websites is cash poor. Tom's hardware has resorted to doing marketing research among their readership for Socratic Technologies. Sometimes they have been overt, sometimes they have sent readers to secure servers just for simple popularity polls. Tom's latest revenue generation technique is the introduction of "Editorial Content Sponsorships" which I'm going to guess prompted the recent editorial change of heart toward Rambus. Please notice that in the most recent article no AMD processors were over clocked according to their projected roadmaps and the test is presented as if it was fiction. Unfortunately, it seems we have lost another fair and unbiased journalist. Another because Sharky's Extreme was the first to go into Intel's pocket, prompting Sharky himself to leave the website. Sharky's is owned by INT Media Group. Noteable investors in INT media include Dell Computer Corporation, International Business Machines Corporation, Lucent Technologies Inc., Macromedia Inc., Microsoft Corporation, Nortel Networks Corporation and Oracle Corporation.
Expect wonderful reviews of Intel hardware on Sharky's and unfortunately now, Tom's. Look to [H]ard OCP, The Inquirer, The register, Anandtech and Ars Technica for relatively unbiased hardware news.
