GeForce GTX 750 vs Radeon HD 5750 1GB

Intro

The GeForce GTX 750 uses a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this specific card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 5750 1GB, which comes with a clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 55 Watts
Radeon HD 5750 1GB 86 Watts
Difference: 31 Watts (56%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 will be 9% faster than the Radeon HD 5750 1GB in general, because of its higher bandwidth. (explain)

GeForce GTX 750 80000 MB/sec
Radeon HD 5750 1GB 73600 MB/sec
Difference: 6400 (9%)

Texel Rate

The GeForce GTX 750 should be much (about 30%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 750 32640 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 7440 (30%)

Pixel Rate

The GeForce GTX 750 is a lot (more or less 46%) faster with regards to FSAA than the Radeon HD 5750 1GB, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 5120 (46%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
