GeForce GTX 1060 3GB vs Radeon HD 6950 2GB


Intro

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

Compare that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
