GeForce GTX 650 Ti vs Radeon R9 M275X

Intro

The GeForce GTX 650 Ti comes with a GPU clock speed of 928 MHz, and the 1024 MB of GDDR5 memory runs at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Compare that to the Radeon R9 M275X, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
