GeForce GTX 750 vs Radeon HD 5770

Intro

Compare all of that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
Radeon HD 5770		108 Watts
	Difference: 53 Watts (96%)

Memory Bandwidth

The GeForce GTX 750 should in theory be a little bit faster than the Radeon HD 5770 in general. (explain)

GeForce GTX 750		80000 MB/sec
Radeon HD 5770		76800 MB/sec
	Difference: 3200 (4%)

Texel Rate

The Radeon HD 5770 should be a bit (more or less 4%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon HD 5770		34000 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 1360 (4%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 is a better choice, though not by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 2720 (20%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
