Under load the power draw of the Athlon II X4 635 PC increases to 211Watts with all four cores under stress. Compared to the considerably faster Core i5 750 processor (169Watts), the Athlon II X4 635 PC system partakes in positively porcine power draw. AMD really needs to move its Athlon II processors to 32nm, but don't expect to see that until at least the second quarter of this year.

Next up, PCSTATS overclocks the Athlon II X4 635 chip to 3.6GHz and beyond, then it's on to the benchmarks.

AMD AII X4 635 CPU Overclocking Report:

Overclocking Results:
Stock Max. OC
Processor Speed: 2.9 GHz

3.625 GHz

Multiplier / Bus Speed: 14.5x 200MHz

14.5x 250MHz

AMD's mainstream quad-core chip, the 2.9GHz Athlon II X4 635 processor retails for just under $120 (2.9GHz / 95W max TDP / 4 cores), so it's a pretty good value on the whole. Given that Athlon II processors lack any L3 cache, a bit of overclocking can do wonders to speed things up a bit.

Before we began our overclocking adventures, the Corsair XMS3-1600C9 memory used in PCSTATS' test system was configured to run in DDR3-800 MHz mode (from DDR3-1066) so it wouldn't hold the CPU back. The Athlon II X4 635 chip was then ready to be overclocked by increasing the bus speed, since its multiplier is locked by AMD. In the past PCSTATS has seen mixed results from the Athlon II chips, but will today be different?

With the socket AM3 processor locked and loaded into Gigabyte's GA-MA790FXT-UD5P motherboard, we set about overclocking the bus speed from 200MHz to 215MHz... then 225MHz... 240MHz and finally 250MHz. That change in bus speed overclocked the 2.9GHz Athlon II X4 635 to a healthy 3.625GHz with no fuss, no muss. However, going beyond 250MHz bus wasn't at all easy; we tried 260MHz only to be greeted with a BSOD upon boot.

After some fiddling, the maximum overclocking result is a fairly conservative 250MHz bus, or 3.625GHz. Not the best result we've ever seen, but not too bad either.

For this review PCSTATS is running the benchmark suite in both Microsoft Windows Vista and Microsoft Windows 7 operating systems. Hopefully this will help you make an informed decision in the coming months as Windows 7 adoption firms up. For the most part, benchmark results are not significantly different between the two operating systems, although certain tests do see advantages under Win 7.

Prelude to Benchmarks

For this review PCSTATS is running the benchmark suite in both Microsoft Windows Vista and Microsoft Windows 7 operating systems. For the most part, benchmark results are not significantly different between the two operating systems, although certain tests do see advantages under Windows 7.

Over the following page we'll be running AMD's 2.9GHz quad-core AMD Athlon II X4 635 processor though PCSTATS standard set of gaming, productivity, and multi-threaded processor benchmarks. There are a wide variety of gaming and synthetic benchmarks here to illustrate what kind of performance boost users can expect from the latest quad-core socket AM3 AMD processor. Please take a moment to look over PCSTATS test system configurations before moving on to the individual benchmark results on the next several pages.
