AMD Athlon II X4 620 & 630: The First $99 Quad Core CPU

DivX 8.5.3 with Xmpeg 5.0.3
Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled:
Four cores and you're good to go with video encoding. The Athlon II X4s are faster than the Q8200 and even the Phenom II X3 720. Intel doesn't have anything that offers better performance at $99 from a video encoding standpoint.
x264 HD Video Encoding Performance
Graysky's x264 HD test uses the publicly available x264 codec (open source implementation of 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 Athlon II X4 continues to beat up on more expensive chips. The Q8200 and the E7500 don't stand a chance. Only the Phenom II X4 and Core i5 are faster.
The Core 2 Quad Q8200 is only able to match the Athlon II X4 620 in performance here. While I'm used to writing that AMD needs to adjust prices downward, here the pressure falls on Intel.
Windows Media Encoder 9 x64 Advanced Profile
In order to be codec agnostic we've got a Windows Media Encoder benchmark looking at the same sort of thing we've been doing in the DivX and x264 tests, but using WME instead.
The Athlon II X4s round up our video encoding tests in the lead. At $99 you can't buy a better quad-core processor, or even dual-core for that matter if you're going to be encoding video.

The L2 cache in the Athlon II X4s are the same as the Phenom II X4, 512KB per core, 2MB total. It is only on the Athlon II X2s that the cache was doubled to 1MB per core, 2MB total.TA152H - Wednesday, September 16, 2009 - link
Oh, OK. I guess I should actually read the charts.Thanks.
Hmmmmm, I wonder why they overclock so poorly. It doesn't make much sense. You'd think it would use less power, and generate less heat. Strange.

Two options: 1) New die, takes time to get the mix perfect for better yields/higher clock speeds, or 2) the chip isn't using super high frequency/high leakage transistors to maximize performance. It could be designed to hit lower frequencies.Take care,

The skeptic in me says bad design problems, like the first Phenoms. That could also account for the multiple delays and pushbacks on the Athlon X4s. But in all seriousness, I have no idea.Eeqmcsq - Wednesday, September 16, 2009 - link
Found this on another site. Perhaps you can check and confirm:"...the imprint "AADAC” identifies the CPU as a Propus."

My 620 is an AADAC while my 630 is an AACYC. I will ask AMD to confirm :)Take care,

Spoke with AMD this morning. The OPN does not indicate whether or not the chip has a disabled L3. It's just luck of the draw, there's no way to tell by looking at the chip itself.Take care,

Please upgrade to a more modern x264 benchmark. I'd recommend a recent handbrake snapshot (http://handbrake.fr/snapshot.php)">http://handbrake.fr/snapshot.php). The nehalem optimizations should boost performance dramatically and are a better representation of what people would get with current encoders.Anand Lal Shimpi - Wednesday, September 16, 2009 - link
I agree completely, the question is more one of when we make the transition. There's a lot of historical data we need to compare to. You'll see a slow transition to new tests especially with the final version of Windows 7.Take care,

Finally we have quad cores at about $100!! Hope that this will spur on better pricing on all fronts! Go AMD, we need the competition to drive down better pricing. Now only if you would drop down the PhII x4 955/965 pricing to compete better with the i5 750!!
