AMD Phenom II X4 940 & 920: A True Return to Competition

DivX 8.5.3 with Xmpeg 5.0.3
Now this is a tremendous victory for AMD. The Phenom II X4 940 doesn't break any performance records, nor can it outshine the Core i7 920, but what it does do is offer the same DivX encoding performance as Intel's Core 2 Quad Q9400. The cache and clock speed advantages are just too much for Intel's parts.
x264 HD Encode
Graysky's x264 HD test uses the publicly available x264 codec (open source alternative to H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
The first pass of the x264 test is a very unique win for AMD; clock for clock it's faster than Penryn here. The trick is that the first pass of the x264 test is mostly an analysis pass, which really benefits from Phenom's integrated memory controller. It's an advantage that no amount of cache can overcome.
The second pass of the x264 encode is where the majority of the work gets done, hence the lower frame rates. The actual encode is happening here and the Phenom II X4 940 ties the performance of the Core 2 Quad Q9400. The same goes for the Phemom II X4 920 and the Q9300. The Q9550 and the Q9400 are faster than the 940 and 920 respectively, but Intel needs to reduce the pricing on both of those parts to remain competitive.
Windows Media Encoder 9 x64 Advanced Profile
Windows Media Encoder has always been an AMD favorite and Phenom II does extremely well here. Again, clock for clock we're at the same performance levels of Penryn, thanks to Phenom's IMC. The Phenom II X4 940 and 920 both outperform their price competitors; in fact, they both perform outside of their price class.

Hey anand, do you think you could grill AMD and see if you can get out of them which chips will be made at the upcoming Malta, NY fab facility? Will it be PII or maybe bulldozer?mkruer - Thursday, January 8, 2009 - link
Anand, I do alot of paring and although the recovery rate is good, i would like to see the results for creating a par2 file.Natfly - Thursday, January 8, 2009 - link
I'm glad AMD is somewhat competitive in the quad core realm but I just cannot get over how blindingly fast the Core i7s are. It is incredible.I hope AMD can make it through, for consumer's (and my stock's) sake. This is a step in the right direction.

Come on, guys! I like a competitive market as much as the next guy but AMD is a whole generation behind. They should have had these when the 45nm C2s came out!AMD is lapped!
It's time for them to die!
CPU standards will only go down if they actually resort to third-party distribution!
Their video cards are always run hotter than NVIDIA and just less stable and overclockable. The only way they was able to stay alive in the race was pitting two of their GPUs against one on one board. NVIDIA hasn't even begun using DDR5 yet!
Intel and NVIDIA is not really receiving competition from AMD. AMD is just lowering standards.

PLAYSTATION THREE is that you?aeternitas - Thursday, January 8, 2009 - link
We would not of had C2D for years, if not for AMD. Please sit down your logic is flawed.Kroneborge - Thursday, January 8, 2009 - link
Oh, let's hope AMD doesn't die. Or you can add a couple hundred on to the price of all your favorite Intel processors lol.Genx87 - Thursday, January 8, 2009 - link
This one is simply not going to cut the butter by the middle of 09. True they are cutting into the Core 2 Duo's performance advantage. It still for the most part falls short. And I didnt see this thing really challange the i7 which will be Intels flagship chip by the end of 09. I dont know about AMD's future chips. But the Phenom needs an arch replacement for AMD to compete with Intel.JakeAMD - Thursday, January 8, 2009 - link
I would suggest an amazing PC experience is about far more than benchmarks or the performance of one component. Some benchmarks today are at risk of losing relevance to real application performance. For example, performance on 3DMark Vantage scores don’t necessarily translate into a better gaming performance. Also, the CPU-only approach to video processing performance is now thoroughly outmoded, as that should be offloaded to the GPU. The Dragon platform technology is really within the budgets people are affording themselves today and we’re doing a better job of serving the real needs of the PC market today. So I would ask you – Is $1000 or more worth the performance difference?Genx87 - Friday, January 9, 2009 - link
I am looking at these gaming benchmarks which is the most intensive thing I do on my computer. My 180 dollar E8400 is cheaper and faster.On the server side the i7 looks more attractive for my virtualization and sql server upgrade project. Where $1000 is pennies on the dollar. Though when you factor in total system cost it is usually not even that much.
Anyways the i7 will come down in price over the course of 09 as a consumer friendly platform is released and the cost of DDR3 falls as production ramps. So it wont cost 1000 more for an i7 system for long. And I question whether an i7 system costs that much more now.
