Geforce GTX 760 vs Radeon HD 5850

Intro

Compare those specifications to the Radeon HD 5850, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5850		151 Watts
Geforce GTX 760		170 Watts
	Difference: 19 Watts (13%)

Memory Bandwidth

The Geforce GTX 760 should in theory be quite a bit faster than the Radeon HD 5850 in general. (explain)

Geforce GTX 760		192256 MB/sec
Radeon HD 5850		128000 MB/sec
	Difference: 64256 (50%)

Texel Rate

The Geforce GTX 760 should be a lot (more or less 80%) better at anisotropic filtering than the Radeon HD 5850. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 41880 (80%)

Pixel Rate

The Geforce GTX 760 is much (about 35%) better at AA than the Radeon HD 5850, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 8160 (35%)

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 data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
