GeForce 9600 GT 512MB vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which features a clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be quite a bit superior to the GeForce 9600 GT 512MB overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X should be a lot (more or less 95%) more effective at texture filtering than the GeForce 9600 GT 512MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 19800 (95%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375X is the winner, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 5840 (56%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
