Comparison: Factory-Overclocked Versus Reference Graphics

Features

In order to set their products apart, third-party vendors take reference GPUs from AMD and Nvidia, then make their own tweaks to layout, cooling, and performance. We're comparing a tuned-up card from MSI to AMD's reference Radeon HD 5870 to measure value.

Benchmarks: Battlefield Bad Company 2

Battlefield is a brand for hefty multiplayer fights. Bad Company 2 still has a single-player campaign, though, in which you and your squad assault enemy trenches or bunkers. Knives and smaller guns are the means with which you start.

Battlefield Bad Company 2 is based on the Frostbite 1.5 3D engine, which we set to high quality. DirectX mode is set to automatic, Horizon Based Ambient Occlusion (HBAO) is enabled, which decreases performance by up to 20%. We typically only test up to 4x anti-aliasing, as Nvidia graphics cards do not support 8x MSAA.

Our test scene is pretty demanding and brings frame rates down to low levels. The GPU is almost always at 100% load. One CPU core keeps running at about two-thirds load, the other three at roughly one-third load.

    i will buy a normal card with good cooling and overclock it.

    Too less performance gain (4-5 FPS) for the too much extra price paid ($50-$70) along with too much increase in power consumption (30-40 W. Better to buy a reference card unless you want the best no matter what the price is.

    I like the idea behind the article and I'm glad that there's been some testing done on it, but I don't really like the article itself.

    There are references to how much the reference card is overclocked by, but there is no clear section about it, you started off with some of the summary charts, instead of putting them after the initial tests and you kept switching what cards you were comparing, with less warning than I would like..

    Plus there's that 2GB 5850. Is that really a 2GB 5850, or is it actually 2GB 5830, because it kept getting beaten by the 1GB 5850..

    When I buy a new GPU, I look for one who's reference clocks make it "good enough" as-is; but I do look for a better / quieter cooler.

    In order to their products apart, third-party vendors take reference GPUs...

    I'm guessing they meant "In order to SET their products apart..."
    Seriously, it's the first sentence in the article. Does no one proof read anything here? Isn't that like the first thing you learn when you want to become a writer? Sorry, rant over.

    "This cooling concept works pretty well, as it not only provides effective graphics component cooling, but it also helps to remove warm air from the inside of your PC. "

    The reference 5870 has a vent on its side so, it doesn't completely remove the hot air from the case but recirculates a part of the hot air back into the case

    It's a 5850, look how close the framerates are.
    The amount of ram doesn't really matter at these resolutions.

    The cards just do not offer enough gain. If you can afford the overclock edition at a premium, then save up a little more and get the next card up or buy two of the next lower cards. The $1000+ dual 5870 from Asus shows what a complete waste of money some, not all, super OC cards are.

    Try this, put together a really really really premium card component wise, and then don't put any cooling on it. Let me decide what I am going to do for cooling and companies can save on packaging, shipping etc due to no cooler.

    If your really aiming at the OC crowd and not just playing a game of marketing, then you know the first thing someone does is to rip off your factory cooler to replace it or at the very least put quality thermal compound on it.
