GeForce 9600 GT 1GB vs Radeon HD 5770

Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 memory runs at a speed of 900 MHz on this model. It features 64 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this particular card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
Radeon HD 5770 108 Watts
Difference: 13 Watts (14%)

Memory Bandwidth

Theoretically, the Radeon HD 5770 should be a lot faster than the GeForce 9600 GT 1GB overall. (explain)

Radeon HD 5770 76800 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 19200 (33%)

Texel Rate

The Radeon HD 5770 should be quite a bit (about 63%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 5770 34000 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 13200 (63%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5770 is superior to the GeForce 9600 GT 1GB, and very much so. (explain)

Radeon HD 5770 13600 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 3200 (31%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
