Geforce GTX 760 vs Radeon HD 5830

Intro

Compare those specs to the Radeon HD 5830, which has a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
Radeon HD 5830		175 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

In theory, the Geforce GTX 760 should be 50% quicker than the Radeon HD 5830 in general, due to its greater bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 64256 (50%)

Texel Rate

The Geforce GTX 760 is quite a bit (approximately 110%) better at anisotropic filtering than the Radeon HD 5830. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 49280 (110%)

Pixel Rate

The Geforce GTX 760 is quite a bit (more or less 145%) better at anti-aliasing than the Radeon HD 5830, and also will be able to handle higher screen resolutions better. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 18560 (145%)

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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
