GeForce GTX 960 vs Radeon HD 6750

Intro

The GeForce GTX 960 uses a 28 nm design. nVidia has clocked the core speed at 1127 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon HD 6750, which comes with a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
