GeForce 8600 GS (OEM) vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X will be 463% quicker than the GeForce 8600 GS (OEM) in general, due to its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8600 GS (OEM)		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 370%) more effective at AF than the GeForce 8600 GS (OEM). (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 31960 (370%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375X is superior to the GeForce 8600 GS (OEM), by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8600 GS (OEM)		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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 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 speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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