GeForce GTX 750 Ti vs Radeon HD 5870

Intro

Compare those specifications to the Radeon HD 5870, which has a clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 1600(320x5) SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
Radeon HD 5870		188 Watts
	Difference: 128 Watts (213%)

Memory Bandwidth

The Radeon HD 5870, in theory, should be quite a bit faster than the GeForce GTX 750 Ti overall. (explain)

Radeon HD 5870		153600 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 67200 (78%)

Texel Rate

The Radeon HD 5870 should be quite a bit (more or less 67%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

Radeon HD 5870		68000 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 27200 (67%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5870 is a better choice, by far. (explain)

Radeon HD 5870		27200 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 10880 (67%)

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: Memory 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. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
