Intel Core i7 (Nehalem): Architecture By AMD?

[jimmysmitty]

[citation][nom]neiroatopelcc[/nom]L2 is low because it no longer needs to be bigger. It isn't shared between cores. It'll just full up from l3 cache later (which is plenty big)as for the memory issue. Who'd want to run 3x1333 if they could run 6x1600 ? any enthusiast will only be satisfied with the best, and 1333 just isn't it. Not even 1600 is. ddr3-1333 is basicly obsolete, and it's not even mainstream yet. It's a disaster really. [/citation]

Well sicne the CPU no longer has a FSB and no longer is tied to the memory the same way I doubt there would be as much of a performance increase with DDR3-1600. Especially considering your going to have 3 channels. Compared to dual channel DDR3 its not really a contest.

When it comes out people will see. Where with a Core 2 Quad higher RAM is better, its not the case with Core i7. The biggest boost Phenom sees from memory is moving from DDR2-800 to DDR2-1066. After that its almost none really. Same will be for Core i7.

Good thing. Interesting is that I held Nehalem in my hands a month ago and it looked impressive. All those thing in this article were presented last month. Very good processor with the integrated memory controller and the integrated Graphics Processor, Intel should have done this a long time ago especially the integrated memory controller.

[citation][nom]jamesalexw[/nom]If it uses NUMA style memory architecture does it mean that XP is finally dead as an OS for the performance crowd? If anyone remembers the AMD 4x4 platform, that was allegedly crippled by XP's lack of speed when running on a NUMA platform - Would make me lol to see all the nubs blasting vista for being slow have to start using it to get their 3D mark scores up....[/citation]
I dare be stupid. But what is numa?
[citation][nom]bkp_duke[/nom]Sorry, but I'm just not impressed by this article.It's a hodge-podge of info that has been presented multiple times by Intel at IDF and reported on other sites.It would be something else if it was NEW info, but everything presented here is old. And usually more in-depth and better-written elsewhere.[/citation]
That the bits of info is available elsewhere is known to most anyone. But for those of us who don't have time to read news articles every 10 minutes its great to see a collection of all the info in one place. Especially since one is inclined to forget a certain feature, because you're hearing about it out of ocntext before the next feature is revealed which makes it useful in the first place.

Only disappointment so far is, that only the toms editor has replied here, and not the author. All my questions still unanswered. Well almost all anyway.

I wish a real engineer would make a comment or two about some of the points raised ...

As for the US Israeli comments you might want to consider they have a prettty strong partnership ... and drop the race angle.

Poke fun at politicians instead ...

Processor design teams comprise staff of all nationalities on them.

The 68000 Chip had some Aussies on it.

Surely we had something to do with the cache on this one because we are the best at cricket ... maybe not the memory controller though because I can't find the ball.

"Some analysts say Intel is facing increasing competition from Advanced Micro Devices and worry that Intel's recently introduced relatively low-priced Atom chip might undercut sales of its more expensive chips. They add that Intel has become so big, it's gotten tougher for the company to keep its revenue growing faster than inflation."

"and worry that Intel's recently introduced relatively low-priced Atom chip might undercut sales of its more expensive chips."

Funny this is said a lot, but it was addressed in the conference call yesterday. Otellini (or maybe Stacy) said that they are seeing no cannibalization by Atom, and even if they did it was a HIGHER MARGIN part then Celeron chips it would be undercutting. While the ASP drops and they may see less revenue, the costs (due to the size of the chip) drop faster so they would see HIGHER earnings.
