GeForce GTX 550 Ti vs Radeon HD 7770

Intro

The GeForce GTX 550 Ti comes with a core clock speed of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Compare all of that to the Radeon HD 7770, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Radeon HD 7770 72000 MB/sec
Difference: 26496 (37%)

Texel Rate

The Radeon HD 7770 is quite a bit (more or less 39%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon HD 7770 40000 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 11200 (39%)

Pixel Rate

The GeForce GTX 550 Ti will be a lot (about 35%) more effective at AA than the Radeon HD 7770, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
Radeon HD 7770 16000 Mpixels/sec
Difference: 5600 (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
