In terms of overall gaming performance, the graphical capabilities of the GTX 970 and the GTX 970 are equal.

The GTX 970 and the GTX 970 have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 970 and the GTX 970 have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 970 was released less than a year after the GTX 970, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition and the GeForce GTX 970 Zotac 4GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition and the GeForce GTX 970 Zotac 4GB Edition are the same, which means the GTX 970 and the GTX 970 have equal limitations when it comes to graphical data transfer.

Both the GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition and the GeForce GTX 970 Zotac 4GB Edition have 1664 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.

The GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition requires 150 Watts to run and the GeForce GTX 970 Zotac 4GB Edition requires 150 Watts. We would recommend a PSU with at least 500 Watts for the GTX 970 and a PSU with at least 500 Watts for the GTX 970. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
