Game Benchmarks: Game Multitasking And Power Consumption

We thought it would be nice to demonstrate how these CPUs handle multitasking, so we ran an AVG virus scan during the World in Conflict benchmark to compare the results with the standard results. Here's what happened:

Wow, there is a dramatic difference there. While the Athlon II X4 got the lowest score in the standard benchmark, once multitasking is involved it quickly takes the lead, as its average frame rate barely moves. The Phenom II X3 was hit a bit harder, and its performance was almost halved. Meanwhile, the dual-core CPUs were entirely crippled during the virus scan, going from an average of 40 frames per second (FPS) to under 10 FPS.

We also included some power-usage benchmarks. Note that we couldn't include the Phenom II X3 710 in this test because we simulated that processor for the performance benchmarks and the results wouldn't be valid:

It is interesting that the high clock speed and extra transistors used in the Phenom II X2 550's 6MB of cache don't affect the power levels much compared to the Athlon II X4 620. The dual-core Pentium E6500 remains the power-sipper of the bunch.

    It's a shame there aren't more games that run like FO3 considering how gorgeous it is yet still being much more accessible based on its focus of CPU power instead of being topheavy on the GPU side.

    If people have a delusion that games are not cpu constrained, it is because, if I recall, an article in Tom's made the assertion that any c2d >3GHz was sufficient.

    Don WoligroskiOne final factor we didn't have time to test this time around is overclocking. When overclocked, would the Phenom II 550 Black Edition become a monster? Would the dual-core Pentium E6500 pull a rabbit from its hat? Or would the Athlon II X4 620 and Phenom II X3 710 be able to hold on to their strengths? If this is something you'd like us to explore, please let us know in the comments section.
    OC potential is one of the most important factors in an article like this. If you can, most deff post an update soon.

    AMD is really evening the playing field with their low cost CPU :) but they should start challenging the Core i7 :(

    I would have to say that overclocking results would be extremely useful. May I suggest that you run the same benchmarks again at two levels, the maximum overclock at stock voltage, and again with maximum stable overclock. Then compare the results to today's benches.

    I would have to agree with some of the poster's above that overclockability is a key factor in this price segment.

    kenjiuchimuraIt's a shame there aren't more games that run like FO3 considering how gorgeous it is yet still being much more accessible based on its focus of CPU power instead of being topheavy on the GPU side.360 ports generally run really smooth on adequite PC hardware, simply because of the archetectual similarities. I personally dont think that FO3's graphic technology is all that great, but the art direction that Bethesda took made it a great looking game.

    Another game that does this really well is Operation Flashpoint 2. Technically speaking, the grapics arent that great. And I notice alot of places where textures and polys arent what they should be for a PC game. But aside from that, the game looks fantastic and runs very smooth even at the highest settings, and it all has to do with art, not technology.

    TheCapuletThe Pentium DC can effortlesly overclock to 3.6, giving it a steep clock edge. And under good air cooling can easily hit the 4Ghz mark. With quality air cooling getting so cheap these days, it's not hard to imagine budget gamers buying great cooling while skimping on the processor budget because of overclocking. This article would have been perfect if it included the OC information and a few quick benchies to show the results. The OC potential makes ALL the difference in the world at this price point.First of all OC is out of the question here in this article since a 100$ CPU is clearly not for an enthusiast user (not even i with a PII 940 don`t use OC) , second OC`ing will only lead to huge power consumption fron the pc performance / watt will drop like hell.

    I would love to see what impact OC has... Imo it's always interesting with budget hardware.

    wintermintWhich of the 4 CPU listed in the article is more future-proof?The AthalonII X4 would deffinately be the more futureproof of the four. Programs and games are rapidly being developed and upgraded to use 4+ threads. And when threaded applications finally hits mainstream, you'll appriciate those one or two cores a whole lot more. (Not to mention the platform itself lends itself to future upgrades a whole lot better than the 775 platform.)

    well amd always pwns on the lower end but what i want to see is them pull out a demon with shiny guns that can gut an i7 clean. then we can start the partying (and new systems)
