GeForce 8600 GTS vs Radeon R9 M375X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be quite a bit faster than the GeForce 8600 GTS in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8600 GTS		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The Radeon R9 M375X will be much (approximately 276%) better at texture filtering than the GeForce 8600 GTS. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8600 GTS		10800 Mtexels/sec
	Difference: 29800 (276%)

Pixel Rate

The Radeon R9 M375X is quite a bit (about 201%) faster with regards to FSAA than the GeForce 8600 GTS, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8600 GTS		5400 Mpixels/sec
	Difference: 10840 (201%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are processed per second. This is worked out by multiplying the total 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 applied in one second.

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