AMD Athlon II X4 640: 4-Cores On The Cheap

15 thumbs up

 

Test System Configuration Notes: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory timings for DDR3-1333 with 8,8,8,24 timings. The hard drives were then formatted, and Windows 7 Ultimate x64 was installed. When the Windows installation was complete, we updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, performed a disk clean-up, defragged the hard drives, and ran all of the tests.

 Preliminary Testing with PCMark Vantage
 Synthetic Benchmarks

First up, we ran our test systems through Futuremark’s latest system performance evaluation tool, PCMark Vantage. PCMark Vantage runs through a host of different usage scenarios to simulate different types of workloads including High Definition TV and movie playback and manipulation, gaming, image editing and manipulation, music compression, communications, and productivity.  Most of the tests are multi-threaded as well, so the tests can exploit the additional resources offered by a quad-core CPU.

 

As expected, the new Athlon II X4 640 performed slightly better than the Athlon II X4 635 it supplants at the top of the current Athlon II CPU line-up in PCMark Vantage. It also traded victories with the Intel Core i5-661 and much older Q9400.

Yea, the link in the comments stub is broken even though the article is up.  Try this sylv3rblade

*EDIT*
The Futuremark numbers don't seem to jive with the rest of the test.  The 640 looks like a moster compared to the 635 in Futuremark but is not much better in all the other test.  Since this is just a clock increase without any tweaking of the core something seems off.  Any ideas?

This is what AMD always does. Good bang for the buck. Nowadays, even inexpensive PC's can, and do, have cutting edge features combined with acceptable performance. While it's true that they're not breaking any speed records, they're robust enough to game with using a proper Video card.

Even though I personally am not in the market for one, I'm glad to see them here, and at their modest price points as well. AMD helps to keep Intel's prices in check.

In test system there are two 635's where one should be a 640.

Shame you guys didn't have any of the "Athlon II XXXe" to test out, nice review nonetheless.

It is a real shame HH doesnt do CPU-Z screenshots, then things could be easily explained. Take a good look at the part number. For the Phenom chips, the last two letters, GI meant revision C2, and GM meant revision C3. This new 640 is a new revision. So not only did the 640 get a speed increase in mhz, it got a core revision as well. Maybe these chips are actually disabled "deneb" chips, but Propus has its own die. Any process improvement will eventually trickle down to the mainstream and budget line ups eventually. This is why on the tests that there are more substantial differences in scores with seemingly no explanation why when a 100mhz bump in speed would not be thought of as doing to much to the scores.

@sylv3rblade - Thanks for the head's up, link was fixed as soon as we saw your post.

@InfinityzeN - I think you were right, and were was an issue with some Vantage scores. I was experimenting with AoD before benchmarking, and although I had reset back to defaults, I have a suspicion the CPU wasn't stock for the Vantage tests. Re-ran the tests and have updated.

@Drago - Added CPU-Z shots to page 1. Would normally do this for a full-blown article, but had a VERY limited time with this CPU and focused solely on performance.

I am still ticked off at AMD for their crappy marketing!
 
I guess from their standpoint it is good to make people buy the top of the line then come out with similar products a few weeks later at half the price! Without any heads up of what is on the horizon! Or even the next week!
 
I am trying to let them know about it. They have all these pages for Consumer relations, yet you cant email anyone that might matter :P
 
With the $700 I would have saved from getting the 7800 instead of the 8800, I could have upgraded my entire rig for better rendering performance. Since the only difference would be the 160 core processors, that I don't need since I am not in the science Field! :P

How does your system work with the card you did buy? Can you work properly now?

Happens sometimes. Granted I won them from here, but still pops your bubble a bit. A week after I got my 2 4870s they came out with the 4890s. Faster and cooler running.

 

I am really loving these AMD CPUs right now though. A lot of the people in my TF2 community have come to me in the last few months wanting to build new PCs on tight budgets. I was able to get someone a x3 system for under $500 and found a really nice combo on newegg with a Athlon X2 full system for $370. Even though it was integrated graphics. Still miles better than the Pentium 4 system he was using.
