GeForce 8600 GTS vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which has a core clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be 125% quicker than the GeForce 8600 GTS overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon R9 M375X will be a lot (more or less 276%) faster with regards to 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 a lot (approximately 201%) more effective at anti-aliasing than the GeForce 8600 GTS, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 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, HDR and higher screen resolutions.

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