GeForce 8600 GT 256MB GDDR3 vs Radeon R9 M375X

Intro

The GeForce 8600 GT 256MB GDDR3 features a GPU core clock speed of 540 MHz, and the 256 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should perform quite a bit faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)

Radeon R9 M375X 72000 MB/sec
GeForce 8600 GT 256MB GDDR3 22400 MB/sec
Difference: 49600 (221%)

Texel Rate

The Radeon R9 M375X is a lot (approximately 370%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce 8600 GT 256MB GDDR3 8640 Mtexels/sec
Difference: 31960 (370%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (approximately 276%) better at anti-aliasing than the GeForce 8600 GT 256MB GDDR3, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce 8600 GT 256MB 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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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.
