GeForce GTX 750 vs Radeon HD 7750

Intro

The GeForce GTX 750 makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the Radeon HD 7750, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

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

Texel Rate

The GeForce GTX 750 is quite a bit (approximately 28%) more effective at texture 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 (about 28%) more effective at anti-aliasing than the Radeon HD 7750, and also should be capable of handling higher resolutions while still performing well. (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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface 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 bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
