GeForce GTX 750 vs Radeon R9 M280X

Intro

The GeForce GTX 750 uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Compare all that to the Radeon R9 M280X, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
