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

Power Consumption
Without power gating the Athlon II X4 draws as little power as possible, noticeably less than any of AMD's other multi-core CPUs. Our X4 620 sample was a bit more power hungry than our 630.
Even under load the power consumption story is a good one. Given the position of our Q8400 sample here we'd say that the Q8200 would probably use a bit less power, but the price differential should more than make up for it.
Overclocking
As I mentioned at the start of this article I managed to hit 3.25GHz on the Athlon II X4 620 without any additional voltage using the retail AMD cooler:
I could hit 260MHz x 13.0 for 3.38GHz by upping the voltage, but the gain wasn't worth the additional power usage. Anything higher wasn't possible without more exotic cooling or much more voltage. The performance improved handily at 3.25GHz:
| Processor | Adobe Photoshop CS4 | x264 2nd pass | Left 4 Dead |
| AMD Athlon II X4 620 (2.6GHz) | 27.5 seconds | 15.4 fps | 93.2 fps |
| AMD Athlon II X4 620 @ 3.25GHz | 23.2 seconds | 18.9 fps | 102.9 fps |
| AMD Phenom II X4 955 (3.2GHz) | 22.3 seconds | 19.1 fps | 121.4 fps |
| Intel Core 2 Quad Q8400 | 21.8 seconds | 17.9 fps | 105.6 fps |
At 3.25GHz the Athlon II X4 ends up faster than the even more expensive Q8400in some cases, and gets much closer in others. In applications where the large L3 cache isn't missed, the overclocked Athlon II can end up being a poor man's Phenom II X4 955. But looking at the Left 4 Dead performance, there's no such thing as a free lunch - the overclocked Athlon II isn't quite that good.

Typo on page 2."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 620 outperforming it - all at a lower price."
Should be 630.

We look at the TOTAL system power consumption.We look at the TOTAL system performance.
Why do we compare prices of single components?
If you consider TOTAL system cost, we don't look at 60% price difference. It falls to, what, 10%?
And then even CPUs that cost more make sense.

Does not make any sense in my opinion. I already have a case, a PSU, a DVDRW, several hard drives.... I'm not going to be replacing those for no reason. If you want complete systems compared, go look at system builder prices.mapesdhs - Wednesday, September 16, 2009 - link
Anand, could you include a 3GHz AM2 Athlon64 X2 6000+ into the mix
when doing these reviews please? It would be incredibly useful to
know how the Athlon IIs and Phenoms compare to the dual-core
Athlon64s (no need to compare to anything other than the 6000+). My
older Asrock system is a 6000+ and the mbd can take the Phenom2 X4
3.2GHz - but is it worth it? I don't know. Reviews keeping leaving
out the Athlon64 X2, or if they do then it's some pointless low-end
such as a 5600+.
I expect Asrock will add BIOS support for these Athlon II X4s aswell,
so again some comparison numbers would be good to know.
And given earlier articles here and elsewhere, these new CPUs could
also be a very handy upgrade for those trying to get the most out
of AGP systems.
Ian.
PS. To everyone else: don't respond to the trolls. They merely seek
attention. Replying just fans the flames and is exactly what they
want. They know full well the points made back at them are correct,
but that's not why they're posting. Best thing to do is ignore them.

Agree about including the X2 6000+ (great article though Anand).About trolls, AMD and the dragon: Myself is an AMD fan by consumer politital bias. I will always buy and use AMD. Therefore I love to read about a good product they have released. Beeing objective and fair, there are no ways today for an AMD chip to beat the Intel dito.
Hmmm..here everyone knock their heads into the wall - including me: What are we going to compare? Which chip, what cost (incl power eg), plattform etc. Even I hurt my head quite a bit. I've been into hardware for 17 years now (RIP Cyrix!).
The only real straightforward answer I give folk is: what (purpose) are you going to use the chip (computer) to/for? Next question is how big wallet you have and how much you are ready to spend. If money isnt a matter, then we don't need to speculate about whether superman or batman are the best; just buy the most expensive you can get hold of (and if that's not 'nuf - buy some more! In fact it isn't hard to build a system for $200 000. Just a money issue.. ).
I guess most people doesn't have that kind of resources, and the one who has certanly doesn't write comments here. We DO care about prices
and want to have as much as we can have for as little money as possible. Therefore I am convinced that when we messaure chips (consumer stuff) we have to look at the same price. It's not hard to imagine that a $100 000 car is better and fancier then a $10 000. It's also not to hard to understand that most people are going for the $10 000 car.
But if the difference isn't a factor 10 but more like...hmm x 1.2?
Back to basic: how big is your wallet and what are thoose xtra quids leave you with? Purpose again! I KNOW that most people can't tell the difference sitting in front of a 1.7 Ghz Sempron socket A and a core 2 duo 2.2 Ghz. Ever. I'm not talking to you computer freaks, I am talking ordinary stupid user here.
And what I really miss here Anand(You AMD-freak! :-)): Where are the test under Linux enviroment? Take thoose champ for other purposes and you'll come up with some different results..whereas Intel arent fed by MS-platform. Cryptography, MD5 checksum, fileserver etc are test I really miss. I do a lot of video encoding (always in Linux) and would love to see charts from a Linux platform (Yea yea, Phoronix is da shit, but I simply love Anandtech).
I'd better stop now - I know they throw thing @ AMD fans like me..
Peace!

If they launch one of these at a 45w TDP, it could be great for a small form factor system with a uATX mobo. HTPC...arjunp2085 - Wednesday, September 16, 2009 - link
Hi ,Was searching for Phenom X4 9850 Does not seem to be in the list .. Its not that old In my region where i live that's almost the price range the Phenoms sell for,,,
If possible Please Try adding those charts Does Athlon X4 beat Phenom X4???

That's a bloody nice deal. So it's only about 70% as powerful as the top of the line processors. It has more than enough processing power for 90% of computer users, and it can handle all the latest games.P.S. "Overclocking suffers a bit as the chips capable of the highest clocks are destined to be Phenom IIs" I can understand that they'll turn a few crippled Phx4s into A2x4s, but why would overclocking suffer on a deneb A2x4 just because some cache has been disabled? Can you please clarify this?
PrinceGaz - Wednesday, September 16, 2009 - link
Doesn't the part "the chips capable of the highest clocks are destined to be Phenom IIs" answer your PS? They test roughly how fast each chip can run, and bin them accordingly. The faster ones end up as Phenom II, the not so fast ones become Athlon II.
