GeForce GTX 550 Ti vs Radeon HD 7750

Intro

The GeForce GTX 550 Ti features core clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Compare those specifications to the Radeon HD 7750, which uses a 28 nm design. ATi has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750 55 Watts
GeForce GTX 550 Ti 116 Watts
Difference: 61 Watts (111%)

Memory Bandwidth

Performance-wise, the GeForce GTX 550 Ti should in theory be quite a bit better than the Radeon HD 7750 in general. (explain)

GeForce GTX 550 Ti 98496 MB/sec
Radeon HD 7750 72000 MB/sec
Difference: 26496 (37%)

Texel Rate

The GeForce GTX 550 Ti will be just a bit (more or less 13%) more effective at AF than the Radeon HD 7750. (explain)

GeForce GTX 550 Ti 28800 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 3200 (13%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, and very much so. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
Radeon HD 7750 12800 Mpixels/sec
Difference: 8800 (69%)

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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
