GeForce GTX 750 vs Radeon HD 7750

Intro

The GeForce GTX 750 has a clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Compare all of that to the Radeon HD 7750, which features GPU clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 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 will be 11% quicker than the Radeon HD 7750 overall, due to 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 (more or less 28%) faster with regards to AF than the Radeon HD 7750. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 is superior to the Radeon HD 7750, and very much so. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
