As explained, NVIDIA doesn’t set default clock rate for the GeForce GTX 560, so it is up to the video card manufacturer to decide which clocks to use. Zotac decided to configure its GeForce GTX 560 Multiview with the same clocks as the GeForce GTX 560 Ti. However, the GeForce GTX 560 Ti has 384 processing engines, while the GeForce GTX 560 has 336.
This difference in the number of engines made the standard GeForce GTX 560 Ti to be between 4% and 14% faster than the Zotac GeForce GTX 560 Multiview in our tests, except on Lost Planet 2 and StarCraft II, where both video cards achieved the same performance.
The main problem of the Zotac GeForce GTX 560 Multiview, however, is competition. The Radeon HD 6870 was up to 17% faster than the Zotac GeForce GTX 560 Multiview on our tests, except on Far Cry 2, where the Zotac GeForce GTX 560 Multiview was between 3% and 12% faster; on Lost Planet two, where the reviewed card was up to 5% faster; and on Star Craft II, where both cards achieved the same performance. Also, the Radeon HD 6870 supports six video monitors, and if you research carefully, it can be found for less money.
