Next month's Intel Developer Forum will include a thorough airing of the company's new design philosophies, said Mooly Eden, vice president and general manager of Intel's Mobile Platforms Group. The company plans to brief hardware developers, partners, and analysts on the nitty-gritty details of its new microarchitecture, which is set to replace Intel's blueprints for desktop, mobile and server processors.
"We believe we'll be able to open a major gap," with the new processors, Eden said. Eden led the design team that created the original Pentium M processor, which is credited as the inspiration for Intel's embrace of low-power design philosophies and the model for Merom and Conroe. Merom and Conroe are expected to launch for notebooks and desktops, respectively, in the second half of this year.
The awkwardly titled Next-Generation Micro-Architecture (let's call it NGMA) has yet to receive a catchy name like Netburst, the Pentium 4 architecture it is replacing. But Eden believes it will quickly grab the attention of PC vendors, chip reviewers and analysts who have anointed the AMD64 architecture as the current performance leader. Intel has already disclosed a few details about NGMA. It uses 14 pipeline stages instead of the 31 used by Intel's Pentium 4 processors. Information is processed through a processor's pipeline. The more stages in the pipeline, the less work each individual stage performs, requiring the chip to run very fast and therefore very hot. Intel has moved away from that design strategy in favor of smaller pipelines that do more work per stage, and can therefore run at slower clock speeds.
The microarchitecture also allows the processor to issue four instructions per clock, rather than three, as on Intel's current chips. It uses advanced branch prediction technology borrowed from the Pentium 4 designs. And chips built on that microarchitecture will also share the unified cache introduced with the Core Duo processor, Eden said.
Chips built with NGMA will use 4MB of cache memory, Eden said. Cache memory stores frequently used data right on the chip, where it can be accessed much more quickly than data stored in external memory. Unifying the caches on a dual-core processor improves performance by expanding the amount of cache each core can utilize, which will produce a huge improvement on single-threaded applications that only use a single core, he said.
The combination of all those architectural changes will allow Intel to outperform AMD's planned offerings for the second half of 2006 without having to resort to adopting AMD's integrated memory controller design, Eden said. "It will take at least a year and a half to two years to close such a gap."
Intel has been hesitant to embrace the integrated memory controller since the failure of its last attempt to use such a design. Integrating the memory controller allows that vital gateway between the CPU and the memory to run at the speed of the processor, whisking data into the processor at a high rate of speed. But it also forces the processor to be designed specifically for a certain type of memory, which doomed Intel's Timna processor when its integrated memory controller was designed for Rambus' short-lived RDRAM standard.
Instead, Intel will count on its microarchitectural improvements and a faster front-side bus to deliver the 20 percent improvement in performance over AMD's chips, based on standard benchmarks, Eden said.
AMD is not planning any major architectural changes to its processors this year, but it does plan to introduce support for DDR2 (double data rate 2) memory. That memory standard can reach faster speeds than the current DDR memory used by AMD's chips, which will improve the performance of AMD-based systems.
The Spring Intel Developer Forum kicks off March 7 at the Moscone Center in San Francisco.

First close the one that exists :) (GO, AMD!)

INTEL is 5 generations behind AMD
Who believe this Mooly Eden's shameless bragging of the old stuff. It was the American Bob Colwell who designed Pentium Pro, the middle-east amateurs just improved it, and call it revolutionary.
Why did you have to make the ?middle east? comment???????????
As far as having a Pentium pro architecture??..yeah I am sure its basically the same thing shrunk to .65??NOT. Sure some of its base design might be the same?but how does anyone really know until it comes out.
Also there was a rumour that AMD is already prepared to implement ZRAM technology in its caches. Most caches these days are made with SRAM technology, which requires around 5 transistors to create one RAM cell. ZRAM is a technology that can do this with one transistor! Therefore if AMD wanted to, it could implement a 4MB ZRAM cache in less space than it takes to put on 1MB SRAM cache.

One thing Yonah won't have, at least initially, is the ability to run 64-bit applications.

"We made a conscious decision not to include it" because of the impact on battery life, Eden said.
Intel's hype does smell a lot like Microsoft's these days. They are playing catch-up and not making-up much ground. They would be better served to adopt more of what AMD has done, then start to make the chip design their own again. This game of trying to mask the major short-comings of their current design can't last.
I'm not anti-intel, I just want the best CPU out there, and right now that is an AMD chip.

"There definitely are people who are highly skeptical, who think this is all fluff, all just gloss -- that if you make good technology, you don't need the glitz," says Genevieve Bell....
"People are smart enough to pick quality when given a choice, and calling something a platform doesn't guarantee quality," Ruiz says....
One example of the new approach is Bern Shen. A doctor who practiced internal medicine for 15 years, he joined Intel three months ago to help develop technologies for digital health. He works with Intel's ethnographers to figure out which technologies might help in monitoring the vital signs of the elderly or tracking the diet of people with Alzheimer's. "The fact that they hired me is an indication of the new Intel," he says.
"They are pushing some very innovative approaches, in areas that relate to dementia, Alzheimer's care, and Parkinson's disease."
Says Schmuel "Mooly" Eden, an Israeli engineer who helped spearhead the Centrino launch and now heads marketing for the Mobility Group: "When I went back to Israel to talk to some of the engineers, they said: 'You're only one year in marketing, and already you're brain-damaged."'
We get it. You don't like Intel or Eden.
