GeForce GTX 750 vs Radeon HD 5870

Intro

The GeForce GTX 750 features a core clock speed of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 5870, which has core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 ROPs.

GeForce GTX 750 80000 MB/sec
Difference: 73600 (92%)

Texel Rate

The Radeon HD 5870 should be a lot (about 108%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon HD 5870 68000 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 35360 (108%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5870 is a better choice, and very much so. (explain)

Radeon HD 5870 27200 Mpixels/sec
GeForce GTX 750 16320 Mpixels/sec
Difference: 10880 (67%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many 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.
