Reviews Word on the street for the AMD Athlon II X4 640


9.1
The only bad thing would be that I couldn't get past 3.6GHz with it but hell it was 100 and out performed the Q6700 I paid 250 for two years before.

What People Are Saying Give it to me straight

Socket Type

By cranking the voltage up to 1.575V in the motherboard's BIOS we were able to get the FSB up to 255MHz and the system to an overclock of 3825MHz.

Two of the Corsair Dominator memory modules were run in dual channel mode at 1600MHz with 8,8,8,24 timings.

The ASRock 890GX was running the latest Bios version 1.8.

Socket

The ASRock 890GX Extreme3 motherboard that we used for testing had a fairly decent BIOS that allows you to overclock a processor like the Athlon II X4 635 quickly and easily.
by Legit Reviews (May, 2010)
We should also point out that the AMD Athlon II X4 630 processor that we reviewed back in September 2009 was able to reach 3.85GHz with 1.55V. It would appear that the AMD Athlon II X4 series can get to roughly 3.8GHz with a little work and a good overclocking motherboard as we've had a few of them up at this clock frequency now on just air cooling.

The ASRock X58 Extreme3 motherboard was running BIOS version 1.4.

Applications

The game also will have hardware tessellation that is said to improve the appearance of water and other surfaces, as well as crowd animations.

All in game settings were set to their maximum.

From desktops and laptops to workstations and gaming rigs, by comparing your PCMark Vantage score with other similar systems you can find the hardware and software bottlenecks that stop you getting more from your PC.
by Legit Reviews (May, 2010)

Performance

The drawback to this benchmark is that it doesn't take multi core performance into account.
by Legit Reviews (May, 2010)
Typically speaking the performance of memory will go up with a faster CPU, though it didn't here.
by Legit Reviews (May, 2010)
Granted, the Intel system did lead on all the tests, but the performance wasn't anywhere near double like the price is.

Gaming

A PcMark score is a measure of your computer’s performance across a variety of common tasks such as viewing and editing photos, video, music and other media, gaming, communications, productivity and security.

Batman: Arkham Asylum is an action-adventure stealth video game based on DC Comics' Batman for PlayStation 3, Xbox 360 and Microsoft Windows.
by Legit Reviews (May, 2010)
Pair it with a system board like the ASRock 890GX Extreme3 that we used today and you have the base for a solid gaming or multi-media system.
