GeForce 8800 GTX vs Radeon R9 M365X

Intro

The GeForce 8800 GTX comes with a core clock frequency of 575 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 384-bit bus, and makes use of a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare all that to the Radeon R9 M365X, which features a clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTX should theoretically be a bit faster than the Radeon R9 M365X in general. (explain)

GeForce 8800 GTX 86400 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The Radeon R9 M365X should be a small bit (approximately 1%) more effective at AF than the GeForce 8800 GTX. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 200 (1%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M365X is a better choice, but it probably won't make a huge difference. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 1000 (7%)

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 data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
