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

Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
Like Blender, we have another highly optimized Intel case - but even here the Athlon II performs admirably. It's faster than the Phenom II X3 720, slower than the Q8200 but faster than the E7500.
It's priced like an Intel dual-core processor, but outperforms it in even the most Intel-favored situations.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spent encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
The Athlon II X4 620 goes back to delivering the goods. Faster than a Q8200 and an X3 720 once more.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
More of the same here.

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,
Anand

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!!
