The GTX560 has proven to be a popular card for Nvidia building upon the incredible success of the GTX460. The reference card has 7 SMs, 32 ROPS, 512kb of L2 cache, 336 SPs and 1GB of GDDR5 memory connected via a 256 bit memory bus. This Sparkle GTX560 card is equipped with double the memory (2GB GDDR5) with a higher core clock speed (822mhz). This is sure to enhance performance at higher resolutions when image quality is cranked. The card is built around the GF114 core, which features 32 ROPS, 336 CUDA cores and 2GB of GDDR5 which is connected via a 256 bit memory interface. The core clock is 823mhz, and memory is set at 1002mhz (4008mhz effective). We didn’t manage to get a great overclock from the memory, analysing some minor artifacts when pushing past 1039mhz. We managed to push the core to 886mhz, which translates to an overclock a little less than 8%. The overclock gained noticeable results from 3DMark 11, improving the score by around 300 points to 4,525. This pushed the performance past the reference clocked AMD HD6870.
