GeForce GTX 650 Ti 2GB vs Radeon HD 7750

Intro

The GeForce GTX 650 Ti 2GB uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory works at a frequency of 1350 MHz on this specific card. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon HD 7750, which has a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Radeon HD 7750 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be a lot (approximately 132%) better at AF than the Radeon HD 7750. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 33792 (132%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon HD 7750, but it probably won't make a huge difference. (explain)

GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Radeon HD 7750 12800 Mpixels/sec
Difference: 2048 (16%)

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 data (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 the graphics card can 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 colour ROPs by the the core clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
