55nm GeForce GTX 285 shows up too

We reported recently on the launch of the GeForce GTX 295, a single board SLI product created using GT200b, NVIDIA's 55 nm shrink of GT200.  NVIDIA have quietly shoehorned the chip into a single-chip board too, creating the world's fastest single-chip product to date, eclipsing the GeForce GTX 280 by a small but reasonable margin.

The shrink to 55 nm (with the chip still produced by TSMC) affords NVIDIA some extra thermal and power headroom versus GT200 and GeForce GTX 280.  NVIDIA use that room to up the clocks across the board.

Base clock is 648 MHz, up from 602; hot clock is 1476 MHz, up from 1296 MHz; memory clock is up to 1242MHz, from 1107MHz on the GTX 280.  The headline figures aren't anything an overclocked GTX 280 couldn't do, probably even on stock cooling, but GTX 285 gives you them for free of course and with its own headroom for more frequency at your (or the board vendor's) behest.

Indeed, HEXUS reported on Inno3D's 700 MHz base, 2500 MHz mem version last Friday.

For an in-depth analysis of the 285 and 295, head over to the Tech Report.  Scott whips up an analytical storm, checking out the new products in great detail before pitting them against some choice Radeon configurations (the 2 GiB HD 4850 X2 looks great!) to see what comes out on top.

NVIDIA sit on top of the single- and dual-chip single-board pile with the new 55 nm parts, and although the prices might make some think twice, they're attractive because of their lofty position to more than a few.  The 295 is still the best CUDA dev board on the planet, after all.
