Details of New Intel Dunnington and Nehalem Architectures Leaked 147
Daily Tech is reporting that details about Intel's new processor models were leaked over the weekend. Both the six core Dunnington and Nehalem architectures were featured in this leak. "Dunnington includes 16MB of L3 cache shared by all six processors. Each pair of cores can also access 3MB of local L2 cache. The end result is a design very similar to the AMD Barcelona quad-core processor; however, each Barcelona core contains 512KB L2 cache, whereas Dunnington cores share L2 cache in pairs. [...] Nehalem is everything Penryn is -- 45nm, SSE4, quad-core -- and then some. For starters, Intel will abandon the front-side bus model in favor of QuickPath Interconnect; a serial bus similar to HyperTransport."

I've always liked the way Intel code names their processors, as I was born and raised in Tillamook, which had it's own Mobile Processor. Nehalem, is in fact another city in Tillamook County, Oregon. Some of you might remember Nehalem's prior claim to fame was an Everclear song on their breakthrough album Sparkle and Fade, entitled simply 'Nehalem'.
Don't forget the notorious Willamette chip!! Though I'm not sure if anyone wants to be known for that...

In order to spike both cores, I need to start something like a compiler or video encoder, which is going to also eat I/O time. Its the I/O that slows down WoW more then the CPU usage. Since adding four more cores drastically increases my parallel processing power (which I don't need more of now), and doesn't do a thing for my I/O throughput (which I do need more of), its not really all that helpful.
Thats why this doesn't excite me a whole lot. We were already at a spot where a single core is more then fast enough for a majority of mainstream users, and now we're going to give out six of them? Other then being able to run spyware more effeciently, whats actually being gained?

For that, a dual core is an excellent idea, a quad core is not. A quad (or sex?) core is only useful when your workload can be divided into 4 roughly equal parts.

Intel currently has the superior technology, this is because of superior fabrication capabilities, not because of a superior architecture, if I've been following this correctly over the last few years. The general public is oblivious to the fact that internally the AMD architecture is cleaner and more elegant, the only thing they have to go on is marketing. If Intel were to adopt HyperTransport, which IIRC is trademarked by AMD, that would be a huge step backwards for Intel marketing, which is just recovering now that the Core 2 architecture has put them back on top.

Note that Intel did adopt AMD's 64-bit extensions to the x86 instruction set. I regard that as far more significant than, hypothetically, licensing HyperTransport. For example see this article on Wikipedia [wikipedia.org] or any other history of AMD64/Intel64 or "x86-64" or whatever everyone is calling it these days.
