GeForce GTX 1060 3GB vs Radeon HD 6950

Intro

The GeForce GTX 1060 3GB features a GPU core clock speed of 1506 MHz, and the 3072 MB of GDDR5 memory runs at 2000 MHz through a 192-bit bus. It also is made up of 1152 SPUs, 72 Texture Address Units, and 48 ROPs.

Compare those specifications to the Radeon HD 6950, which makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular model. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
