Zotac GeForce GTX 280 AMP Edition While AMD seems to be concentrating on making the mainstream market its own, Nvidia has continued to hang onto its crown as king of the hill when it comes to outright performance. Cementing that place even further is the company's latest hi-end GPU, the GTX280.
The GT200 upon which it's based is the company's second generation DX10 core and is more an evolution of the highly successful G92 GPU - which was seen by many to be a die shrink of the even more successful G80 - than a new design from the ground up.
But by revamping the good parts of the previous architecture and redesigning the less good bits, Nvidia has managed to double the processing power of the GT200 over its siblings. Presently there are just two flavours of the GT200; the GXT260 and the flagship GTX280, the GPU that our review Zotac card is based on.
But it's some evolution: the GT200 is a huge chip. Currently the largest chip that Nvidia has produced at 576mm˛, the 65nm process core contains 1.4 billion transistors. That's some jump from the 690 million of the G80 or the 754 million of the G93.
