But the second table with the dual core 3ghz cpu is clearly not utilising all 4 cores as the dual is nearly a match for the quad intel.
The scalability of the phenom should be better than the intel quad, its been shown via the server chips that the x4 core scales better.
I thought the jury was still out on that one... Yes on >8way systems, but the intel quads are doing fine, and the V8 that intel put up against a 18way Opteron (which was the same core as phenom)... The Intel V8 scaled just as well, and outperformed the opty considerably.
Xeons scale nicely upto 2 sockets (8 cores), but then suffer due to FSB limitations. The old P4 xeons on the other hand didnt scale half as well, as P4 always was held back by poor design and a high reliance on the FSB.
As already shown in a desktop envirionment moving from a 1333 FSB to a 1600FSB gives virtually no improvement for Penryn based processors. Core architecture processors are really good at prefetching data into cache long before its needed by the processor. For the large majority of desktop and server applications the FSB doesnt create the huge bottleneck that some people still claim.
From a personal perspective, I have to admit I was expecting AMD to pull something very fast out, that would cause intel to rush the Nehelem architecture out faster. But if Phenom can only 'match' Conroe (and not even Penryn), then thats going to make it very hard. AMD wont be able to put a super premium price on the processor, and will have to position it as a high speed 'value' processor, not an 'Enthusiasts' chip. Intel are churning out hundreds of thousands of 65nm processors, and the production lines are already making the 45nm Penryn type chips. Intel are in a position where they can create a mountain of 'stock' ready to ship out, and their yields are more than high enough that they can participate in a pricewar.
Nothing I've seen so far from the Phenom range has made me thing, ooh better get rid of my intel system and switch to AMD... If I need more power, I'll simply switch my C2D for an Q6600... or more likely a Penryn Q9550 (think thats the one... 2.67Ghz Quad)
