GeForce 8600 GT 512MB GDDR3 vs Radeon R9 M375X

Intro

The GeForce 8600 GT 512MB GDDR3 has core speeds of 540 MHz on the GPU, and 700 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Radeon R9 M375X 72000 MB/sec
GeForce 8600 GT 512MB GDDR3 22400 MB/sec
Difference: 49600 (221%)

Texel Rate

The Radeon R9 M375X should be much (approximately 370%) more effective at texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce 8600 GT 512MB GDDR3 8640 Mtexels/sec
Difference: 31960 (370%)

Pixel Rate

The Radeon R9 M375X will be much (about 276%) better at FSAA than the GeForce 8600 GT 512MB GDDR3, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce 8600 GT 512MB GDDR3 4320 Mpixels/sec
Difference: 11920 (276%)

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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
