SYSMark 2007 Performance
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
If we only look at the AMD numbers in this chart, there's a pretty nice lineup going on here. The Athlon II X2 250 is slower than the Athlon II X4 620/630, which is slower than the Phenom II X3 730 and all are slower than the Phenom II X4 955. The performance lines up with the pricing, so all is good.
The problem with these cheap quad-cores has always been that you give up a lot in order to get four cores at a low price. The Athlon II X4 appears to break the mold however. The Athlon II X4 620 is priced at $99 and it performs like a $99 CPU. With the exception of the Core 2 Duo E7500 whose high clock speed makes it do unsually well here, the 620 is balanced. You get a reasonably high clock speed and enough cache to be competitive, both at a good price.
You'll see in the individual tests below that performance varies between competitive and underwhelming depending on the task. Anything that can take advantage of four cores does well, otherwise the smaller L2s of the Athlon II X4 hurt it a bit.
In applications that aren't well threaded, you'll see the Athlon II X4 perform less than stellar - but the same is true for all lower end quad-core CPUs. Even the Q8200 is outperformed by the E6300 here. Situations like this are validation for Intel's aggressive turbo modes on Lynnfield.
Any strenuous video encoding however will seriously favor the Athlon II X4. Here we find the $99 620 tying the Core 2 Quad Q8200, and the 630 outperforming it - all at a lower price.
We're back to needing higher clock speeds and larger caches to compete. Being a quad-core processor isn't easy.

I don't know if they intentionally cripple fully functioning denebs. I imagined that amd would rather sell a Phx4 for ~$200 than an A2x4 for ~$100, but I might have read somewhere that both intel and amd do intentionally cripple fully functioning chips.strikeback03 - Wednesday, September 16, 2009 - link
That statement makes sense for harvested Denebs, but doesn't Propus not have any L3 at all, so it can't be turned into a PhenomII?blyndy - Friday, September 18, 2009 - link
Yes that's why I thought the quote didn't make sense -- If propus is exclusively A2x2 then the highest clocking propus' will still be A2x2's, therefore A2x2 overclocking wouldn't suffer.MrPIppy - Wednesday, September 16, 2009 - link
How is the motherboard compatibility situation looking? Will boards need a BIOS update, or just work out of the box right now?Also, does it support AMD virtualization instructions?
Last, any idea about compatibility with ECC RAM? The BIOS often plays a role in this too, but just wanted to make sure AMD didn't remove ECC support from the IMC or something similar

This is a GREAT product from AMD.Make it smaller, make it cheaper, and put it with a platform much better than one Intel can have.
AMD can not make a processor worth a damn. Let's face it, they suck. If they try to compete head on with Intel, they lose, period.
By making a quad core that is more than fast enough for most people, while at the same time reducing the size so they can make it cheaper, they created something in a segment where Intel just isn't.
Couple this with a 790GX, or the 785, and you've got a great platform for a lot of people. If you need the best, or near it, the Bloomfield can't be touched. Why even try? Most people don't need it.
Finally, AMD seems to get it.

I kinda agree with you here. But I cannot understand your need to paint the world in only black and white.khaakon - Thursday, September 17, 2009 - link
* edit;"your need" meaning TA152H

"Finally, AMD seems to get it."Yes, but will they make money out of it? Only time will tell.

Where's that dipshit snakeoil to complain about nonexistent bias?Eeqmcsq - Wednesday, September 16, 2009 - link
He's in disguise under a new screen name. See if you can spot him in the comments so far.
