GeForce GTX 460 vs Radeon HD 5770

Intro

Compare that to the Radeon HD 5770, which features core speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5770		108 Watts
GeForce GTX 460		150 Watts
	Difference: 42 Watts (39%)

Memory Bandwidth

Theoretically, the GeForce GTX 460 should be a little bit faster than the Radeon HD 5770 in general. (explain)

GeForce GTX 460		86400 MB/sec
Radeon HD 5770		76800 MB/sec
	Difference: 9600 (13%)

Texel Rate

The GeForce GTX 460 should be a bit (about 11%) more effective at anisotropic filtering than the Radeon HD 5770. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 3800 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 is the winner, but not by far. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 2600 (19%)

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 largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
