GeForce 9600 GT 512MB vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which comes with a clock speed of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9600 GT 512MB, in theory, should perform quite a bit faster than the Radeon R9 M375 in general. (explain)

GeForce 9600 GT 512MB		57600 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 22400 (64%)

Texel Rate

The Radeon R9 M375 will be a lot (about 95%) more effective at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 19800 (95%)

Pixel Rate

The Radeon R9 M375 should be a lot (approximately 56%) better at AA than the GeForce 9600 GT 512MB, and also able to handle higher resolutions while still performing well. (explain)

Radeon R9 M375		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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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