GeForce 8800 GTX vs Radeon R9 M280X

Intro

The GeForce 8800 GTX makes use of a 90 nm design. nVidia has set the core speed at 575 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.

Compare that to the Radeon R9 M280X, which comes with a clock speed of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X 75 Watts
GeForce 8800 GTX 155 Watts
Difference: 80 Watts (107%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M280X should perform a little bit faster than the GeForce 8800 GTX overall. (explain)

Radeon R9 M280X 88000 MB/sec
GeForce 8800 GTX 86400 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M280X is quite a bit (approximately 37%) more effective at anisotropic filtering than the GeForce 8800 GTX. (explain)

Radeon R9 M280X 50400 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 13600 (37%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M280X is a better choice, though not by far. (explain)

Radeon R9 M280X 14400 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 600 (4%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
