GeForce GTX 960 vs Radeon HD 6670 (OEM) 1GB

Intro

The GeForce GTX 960 comes with a GPU clock speed of 1127 MHz, and the 2048 MB of GDDR5 RAM runs at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which comes with GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
