The Gigabyte 9800GT comes equipped with a Zalman heatsink to vastly improve the cooling performance, which in turn, could lead to higher overclocking potential. With clock speeds of 600MHz on the GPU core, 1.5GHZ on the 112 shader cores and 900MHz on the 512MB of GDDR3 memory, the 9800GT has on paper the same specifications as the 8800GT that came out last year.
