Look at this baby!!!
i want one of these!!!
check this picture i made..i got all the information from the internet.

Information
At first glance, the new Radeon X850 XT Platinum Edition looks much different than ATi's previous flagship card, the X800 XT, but upon closer inspection, the two are actually quite similar. The most obvious difference is the large, two-slot cooling apparatus used on the X850 XT. This new cooler is designed to draw air over the copper-finned heatsink that's mounted atop the GPU and expel it from the case. The fan used in the cooler is throttled according to the GPU's temperature and can potentially get loud. When it's initially powered up, the X850's fan spins at its maximum speed, at which point it is relatively noisy. It was the loudest part in our test system by far. However, after a few seconds the fan spins down and is barely audible. With our test system at idle, we could barely hear the X850. And we'd also like to note that through hours of gaming and benchmarking and through an extended overclocking session, our X850's fan never had to spin up to its maximum speed and remained relatively silent. The potential is there for some noise if GPU and system temperatures get out of hand, but in a well-ventilated case, we doubt the X850 will need to spin up considerably. The advantage of a design such as this is that much of the heat generated by the GPU is expelled from a system, which should help to keep case temperatures in check. The main disadvantage is that a dual-slot cooling solution blocks the use of a slot, and it may not fit in most small form factor systems.
Other differences over the X800 XT include a heat plate mounted to the RAM on the backside of the card, dual-DVI outputs, and higher core and memory clock speeds. The X850 XT Platinum Edition can be configured with a single DB15 analog monitor connector and a single DVI output, but most models will be equipped with dual-DVI. The X850 XT Platinum Edition's core is clocked at 540MHz, and its memory is clocked at 590MHz (1.18GHz). With the cooler removed from the X850, we compared the PCB layout to an X800 XT to see if we could spot any major changes but we didn't find any. The only difference we found was an extra capacitor mounted at the upper left corner of the board near the mounting bracket. The X850 XT Platinum Edition had three caps, whereas the X800 XT had only two.
The R480 chip at the heart of the Radeon X850 XT Platinum Edition is basically a re-spin of the R423 tweaked to take advantage of improvements made to ATi's (TSMC) manufacturing process in an effort to improve yields. Other than the slight alterations made to the core to allow for higher clocks and the addition of some new power-management features, ATi hasn't made any significant changes with the R480..
The R480's optimized silicon has the same base feature set as the R423 that powered the X800 series of PCI Express cards that came before it. We've outlined the R420's features extensively in our coverage of the X800 launch back in May (R420 is the AGP variant). For a more comprehensive explanation of features like 3Dc, temporal AA, and other ATi technology, we recommend checking out that link. The R480 is still built using a 0.13-micron manufacturing process and it still has 16 parallel pixel pipelines, six hardware vertex shaders, and a 256-bit memory interface. And the 2D engine, video processing engine, and display interfaces are all essentially unchanged.
Like the R423, the R480's pixel pipelines are also arranged in four quadrants of four pixel pipelines, which lets ATi disable individual quadrants if necessary. This ability allows ATi to get more usable dice per wafer because dice with only a single defective quadrant, for example, are still usable if they'll run at acceptable clock speeds. Shutting down quadrants also allows ATi to scale down the GPU and release 12, 8, or 4-pipe variants of the same core. Although releasing an 8- or 4-pipe R480 would be a monumental waste of silicon...
ATi's ability to scale the R480 core has resulted in the three new video cards that currently make up the X850 Series. The flagship card is the X850 XT Platinum Edition with 16 pixel pipelines, a 540MHz core, and 1.18GHz memory. These relatively high clock speeds give the X850 XT PE a higher peak fillrate and more memory bandwidth than any other consumer-class video card released to date. The X850 XT is essentially the same as the Platinum Edition but with a lower clocked core (520MHz) and 50MHz (100MHz DDR) slower memory. Then comes the X850 Pro, which is identical to the X850 XT, minus four pixel pipelines, and with a single-slot cooling solution. Look at little further down the chart and you'll find the new X800 XL and X800, which we suspect many of you will like very much...read on...
