GeForce GTX 750 vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is made up of 1120(224x5) SPUs, 56 TAUs, and 16 Raster Operation Units.

GeForce GTX 750		80000 MB/sec
	Difference: 48000 (60%)

Texel Rate

The Radeon HD 5830 should be a lot (about 37%) more effective at texture filtering than the GeForce GTX 750. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 12160 (37%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 is superior to the Radeon HD 5830, and very much so. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon HD 5830		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
