GeForce GTX 750 vs Radeon HD 7750

Intro

The GeForce GTX 750 comes with clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should be 11% quicker than the Radeon HD 7750 in general, because of its greater data rate. (explain)

GeForce GTX 750 80000 MB/sec
Radeon HD 7750 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 should be a lot (approximately 28%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)

GeForce GTX 750 32640 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 7040 (28%)

Pixel Rate

The GeForce GTX 750 should be quite a bit (approximately 28%) more effective at full screen anti-aliasing than the Radeon HD 7750, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon HD 7750 12800 Mpixels/sec
Difference: 3520 (28%)

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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
