Geforce GTX 760 vs Radeon HD 5550

Intro

Compare all that to the Radeon HD 5550, which comes with clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Geforce GTX 760 should in theory be a lot better than the Radeon HD 5550 overall. (explain)

Geforce GTX 760		192256 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 179456 (1402%)

Texel Rate

The Geforce GTX 760 is much (approximately 969%) more effective at anisotropic filtering than the Radeon HD 5550. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 85280 (969%)

Pixel Rate

The Geforce GTX 760 should be quite a bit (approximately 613%) better at full screen anti-aliasing than the Radeon HD 5550, and also should be able to handle higher resolutions while still performing well. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 26960 (613%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
