AMD was right - we do need a new front-side bus. - Adventures in Engineering — LiveJournal

The radical change in Intel's system bandwidth situation that Intel's new QuickPath Interconnect (QPI) represents is perhaps the largest single factor that shaped Nehalem's design. Between QuickPath and Nehalem's integrated memory controller, a Nehalem processor will have access to an unprecedented amount of aggregate bandwidth, especially in two- and four-socket implementations.

What this means is that Intel no longer has to equip its processors with freakishly large unified caches designed to mitigate the effects of the bandwidth starvation with which Intel platforms currently struggle. The chipmaker is now free to use all of the transistors that Moore's Law affords more flexibly and intelligently, and this freedom has profound effects on every aspect of Nehalem.


Let's not forget who redesigned the front-side bus first.

All this buzz around multicore chips is great... I'd like to be able to buy a PC compat with more than 5 cores now, please? PLEASE? SOMEONE???

Also I'd like my games to be able to use more than 3.5 GB of memory if need be, so can you please fix that problem, MicroSoft? Your OS isn't good for anything else, you could at least make games not suck.

I think if you asked them this, they'd point you to the Xbox 360 (which would then erupt in flames). XD

I don't know if it's "done right" but the PS3 is specifically made for multi-core processing.. and you can run linux on it if you just want to toy around? :)

I don't like the PS3's architecture. The level of core specialization is excessive in my opinion and makes it difficult to program. Also, there are no games for Linux... even Linux on the PS3.

I want to next year buy a four-socket motherboard, and put a four core processor in each once a year as a reliable upgrade path, with room for 128G ram, in 8G sticks. I don't know if AMD or Intel will provide that sort of workstation board design anytime soon.
