Engadget reports AMD has introduced a 900MHz version of its Radeon HD 7750 (100MHz more than the original model). XFX is currently offering a Radeon HD 7750 Black Edition Double Dissipation with 900MHz clockspeed for $115 after a rebate, which is just $6 more than the launch price of the original card.
The new card also happens to be called the Radeon HD 7750, and it'll sit alongside its doppelganger on the shelves of the world's computer stores just daring you spot the difference. How will you do that? By checking if it requires a separate power supply: the original 7750 was powered entirely through the PCIe slot, limiting its power to 75W and hence its clock speed to 800MHz, while the new one accepts additional power to deliver slightly more grunt and stay ahead of looming competition from NVIDIA.
