GeForce GTX 1070 vs Radeon HD 6750

Intro

The GeForce GTX 1070 makes use of a 16 nm design. nVidia has clocked the core speed at 1506 MHz. The GDDR5 RAM works at a speed of 2000 MHz on this particular model. It features 1920 SPUs as well as 120 TAUs and 64 ROPs.

Compare those specs to the Radeon HD 6750, which has a core clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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