GeForce 8800 GT 512MB vs Radeon R9 M375X

Intro

The GeForce 8800 GT 512MB uses a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon R9 M375X, which has GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Radeon R9 M375X 72000 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X will be a lot (approximately 21%) more effective at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X will be a lot (more or less 69%) better at AA than the GeForce 8800 GT 512MB, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 6640 (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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
