The GeForce GTX 570 was a performance-segment graphics card by NVIDIA, launched in December 2010. This is an extremely narrow range which indicates that the Nvidia GTX 275 performs superbly consistently under varying real world conditions. EVGA GeForce GTX 570 HD Superclocked, Part Number, 012-P3-1573-KR, Introducing the EVGA GeForce GTX 570. The range of scores (95th - 5th percentile) for the Nvidia GTX 275 is just 1.24. Dubbed a new form of Hybrid SLI, EVGAs latest. So, a video card with a memory chip running at 500 MHz would be referred to as having a 1 GHz memory. In order to make our table comparable to older chips, we still use the effective memory clock and not the real memory clock. With these features and more, the EVGA GeForce GTX 570 HD gives you more than one way to elevate your experience. EVGA has gone and concocted a special Halloween edition of the GTX 275, which has sprouted an entire GTS 250 appendage solely for PhysX gruntwork.

In the past, manufacturers referred to the memory clocks with double (or quadruple) their real clock rate, because DDR and other technologies based on it (DDR2, GDDR3, etc.) allow the memory chip to transfer two data blocks per clock cycle, while GDDR5 memories allow the memory chip to transfer four data data blocks per clock cycle.

It is important to note that beginning in 2007, both AMD (ATI) and NVIDIA started referring to the memory clock of their video cards with the real clock rate used. To facilitate knowing and understanding the differences among these chips, we have compiled the table below. If you don’t follow the video card market almost daily, it is really complicated to understand the differences between the several different NVIDIA graphics chips available on the market today.
