Big memory capacity hasn’t always been specific to the highest-end graphics cards. It's actually still fairly common for vendors to put a bunch of inexpensive, low-speed memory on entry-level boards, hoping that big number would register as better performance to the folks who haven't yet wrapped their heads around the idea that a big frame buffer is of limited use to an underpowered GPU. The uninitiated would readily jump for the “better” specification they knew, rather than the faster graphics processor they didn't understand as well.
But gamers have since become better-educated with respect to hardware, and many of today’s mainstream cards use fewer of the same expensive memory components as their high-end counterparts. For mainstream and better parts, the economic incentive to expand the memory capacities of low-end cards is almost gone.
More recently, the industry has seen an explosion in both graphics processing and system demands, with games becoming increasingly complicated and gorgeous 30" displays supporting 2560x1600 pixel resolutions. Putting aside marketing tricks of the past, the high end just might be where memory really needs to expand.
You won’t find a higher-end graphics processor than Nvidia's GeForce GTX 285, and that’s why Gigabyte chose it as the first model to support two gigabytes of super-fast GDDR3-2400 memory. Hints of a custom design are seen in its combination of HDMI and VGA connections, rather than a fistful of adapters, and bold claims of a “2 ounce Copper Inner Layer” for its circuit board.
Spreading the VGA and DVI outputs across two connections rather than relying on a second DVI-I interface and adapters eliminated the space Nvidia’s reference design used for its S-Video/Composite combo interface. That’s no big loss to most of us, since those legacy TV outputs were only able to support ultra-low resolutions. Anyone putting this much effort into gaming on a home-theater display should certainly have HDMI, or at least DVI by now.
Gigabyte’s custom circuit board doesn’t look much different than the reference-design cards we’ve seen, though Gigabyte claims slight improvements in its voltage regulator components.
Hynix’s super-fast H5RS1H23MFR-N2C 1Gb GDDR3-2400 memory is clocked at its rated speed, though Gigabyte does overclock the GeForce GTX 285 GPU slightly to 660 MHz, compared to the standard 648 MHz. Unlike Gigabyte’s card, reference models also underclock RAM to a 2,322 MHz data rate.
