AMD's Phenom Unveiled: A Somber Farewell to K8

General Application Performance
Right off the bat the numbers aren't looking good for AMD. The Phenom 9600 is priced closest to the Core 2 Quad Q6600, but unfortunately for AMD the Q6600 outperforms it by a healthy 10%. AMD needs a 2.6GHz Phenom to equal the performance of the Q6600, but the 9900 won't be out until next year, when it'll have to face the Penryn based Q9450 and Q9300.
2D Image Manipulation Performance
Once again we broke out the Retouch Artists Photoshop CS3 benchmark, timing a handful of image manipulation operations in CS3:
The Core 2 Quad Q6600 is around 6% faster than the Phenom 9900, 10% faster than the Phenom 9700, and almost 16% faster than the Phenom 9600 which is its closest price competitor throughout the rest of 2007.

Yeah, I was in a similar position a couple months back too but I could tell from the winds that the Phenom wasn't going to be that much better than the Core2 if at all so I sprung for the Q6600. Looks like (unfortunately) my estimation was quite correct =/stmok - Monday, November 19, 2007 - link
...And I guess it looks like the wait wasn't worth it.This article confirms to me I should be leaning towards the Intel C2Q Q9450.

On page 4 titled "Socket-AM2+, Not So Positive?" Anand writes:Currently, the L3 cache/NB on these chips runs at a fixed frequency that's actually lower than the rest of the CPU frequency: 2.0GHz. We tested Phenoms running from 2.2GHz all the way up to 2.6GHz, and in all cases the L3 cache and North Bridge ran at 2.0GHz.
What's the performance impact of this limitation? I don't know how to quantify it. It seems like it might have a material effect on performance. Perhaps Anand can re-run his benchmarks at 1.8 and 2.0 GHz to get a sense of the performance boost when this limitation doesn't exist. From this we might be able to determine how much this shortcoming effects performance at speeds greater than 2.0 GHz.

My Athlon 4200+ (2.2ghz) overclocks to 2.7ghz stable. Anything passed that and the second core skyrockets too high in temp and fails prime95 torture tests, while the first core has yet to fail ANY tests and runs up to 10 degrees C cooler.My point is the individual core overclocking is the only positive I see out of phenom. If i had this ability in my current athlon 4200+, it'd be clocked at 2.7 and 3.2+ easily.

Ahh the old 9700 makes a comeback but too bad it falls a bit below expectations compared to the 9700 GPU by ATI who is now AMD.Maybe there's still time to make some tweaks to the processor?

well.too bad for amd. they are toast it seems.
if it managed to be as cool and quiet, then I would have gone there on a quad because of price plus they have better and more consistently cheap + featured motherboards.
sux.
Well, on that thought, the new 790x motherboards with this actually might be low power when its all set up and done. fx or x I think does relatively the same thing. isnt the chipset supposed to be incredibly low wattage?

Everyone knows AMD processors have always been, and will always be, far superior to the crap from Intel. Any article suggesting otherwise is clear evidence of pro-Intel bias, that indeed you all get weekly checks from Intel for the favorable press. The reality is that most Intel processors really don't even work at all; all the supposed PC's sold with Intel processors secretly use AMD processors instead, but again Intel pays off the companies to say they're Intel Inside. Intel has an endless supply of money because of their unfair business practices and the Magic Money Fairy.JumpingJack - Monday, November 19, 2007 - link
