Discrete GPU Gaming

When comparing CPUs to APUs, one strength shown by team Blue in the past is the discrete GPU performance. When using dual graphics cards at a 1920x1080p resolution, at a lower amount of CPU power overall, there tends to be a significant amount of variance when extra CPU performance is applied. While it seems the overclock numbers are nice for a Pentium, a little extra money for an i3 at stock seems to be the choice here.

All of our titles, except Tomb Raider, get a significant increase from overclocking the CPU.  However, it is worth noting (especially in titles such as Battlefield) that using and i3 from the start gets an even better result. This is because the gaming industry has moved on from the last overclockable dual core Intel CPU - games can now take advantage of more cores, and that jump from 2 cores to hyperthreading lets a high end title stretch its legs a little more than a simple overclock.

    FWIW, On my stock cooler 4.6 Ghz open-air Prime 95 stability test (in-place large FFTs, maximum power consumption) and Battlefield 3 64 player I used Speed fan 4.49 to monitor temps. However, I did notice MSI Afterburner v3.0.1 and HWiNFO64 v4.40 were recording temps 10 to 15 C higher than Speedfan 4.49.

    With that mentioned, I did not notice any throttling during my 4.6 Ghz stock cooler (open air environment) Prime 95 stability test. Nor did I see this during BF3 64 player gameplay.

    It supports ecc ram.

    What type of cooling was used/is recommended in order to get a G3258 to 4.5GHz+? If you need high end air or AIO water ($80-120), it kind of runs counter to the idea of building the cheap, high performing system.

    If you cheap on everything, then it won't ever be high performing. I used a Corsair H80i for these numbers during a nice warm British summer. The best place to start for overclocking would be a cooler with at least four copper heatpipes and a decent fan, then go from there.

    Can you run power draw numbers for this system? Starting TDP for the Pentium is 53 W, I don't think it would run much above 100-150 W overclocked. Stock Intel cooler is rated for 95W, and even your cheapest aftermarket cooler should be good for much more than that.

    System power draw numbers are in the overclocking chart, first page. You probably scrolled past them in order to comment :D

    With my inefficient setup, it registered 93W at peak load at stock, moving up to 131W overclocked to 4.7 GHz.

    My bad...should have re-read. Performing some terrible math here, but if we assume 53W at stock speeds, then that's 40 W system overhead. At 131W at 4.7 GHz, approx. 93W for the CPU. On the edge for Intel's cooler, but definitely doesn't require anything that fancy to cool. An AMD A10 is around 100W TDP. And if you're willing to drop a point or two to 4.5 or 4.6 GHz, the power draw is even less.

    The stock cooler is rated at 95w for how long? Because my experience, even going back to the i7-920, is the stock cooler can't keep a chip running at default frequency/voltage for more than a few hours at full load without throttling. Those coolers were supposedly rated at 130w, just like the CPU. But as the surface area heats up across every mm of fins and the ambient case temp jumps just a few degrees, the performance dips.

    Top-down coolers are a 20th century thing.
  • smunter6 - Monday, July 14, 2014 - link

    the i7-920 is a 130W TDP part. The Pentium is 53W, and even when at max overclock, the total system power draw is only 131W. Totally different ball game.
  • extide - Tuesday, July 15, 2014 - link

    Are you kidding me? ALL stock intel CPU fans will allow the cpu they come with to run at 100% load 24/7 without throttling. If you are having problems making that happen, you are doing something wrong.
