In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition are marginally better than the Nvidia GeForce GTX 970 4GB.

The GTX 970 has a 26 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 970. This results in the GTX 970 providing 2.7 GTexel/s better texturing performance. 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 has a 26 MHz higher core clock speed than the GTX 970 and the same number of Render Output Units. This results in the GTX 970 providing 1.5 GPixel/s better pixeling performance. 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 4GB 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 4GB 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 4GB 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 GTX 970 has 2.7 GTexel/s better Texture Fill Rate and 1.5 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the GTX 970 takes the edge.

The GeForce GTX 970 Leadtek WinFast Hurricane 4GB Edition requires 150 Watts to run and the GeForce GTX 970 4GB requires 145 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 GTX 970 requires 5 Watts more than the GTX 970 to run. The difference is not significant enough for the GTX 970 to have a noticeably larger impact on your yearly electricity bills than the GTX 970.
