![]() It's also rather revealing to compare the 4800's raw computer power with that of NVIDIA's new mega-GPU, the GeForce GTX 280. Despite the 150 per cent increase in shader and texture units, the 4800 Series has just 44% more transistors. To appreciate just how compact it is, try this for size. The result, is an extremely compact and cost-effective graphics chip. ![]() ![]() But what AMD has done is so much more sophisticated than create an oversized 3800 core.Įvery aspect of the chip has been overhauled and redesigned with an eye to both efficiency and performance. It's even based on precisely the same 55nm silicon production technology. This new pixel pounder may offer much the same DirectX 10.1 3D feature set as ye olde Radeon HD 3800. Factor in core clockspeeds that are approximately on a par with the 3800 Series and the result is monumental boost in raw processing power.īut don't get the idea that AMD has merely blown a massive transistor budget to simply cut 'n' paste more functionals units into the GPU core. ![]() The 4800's texture-processing capabilities have also ballooned from 16 to 40 units. ![]()
