GeForce 9600 GSO ASUS 512 vs Radeon R9 M270X

Intro

Compare all of that to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Radeon R9 M270X		29000 Mtexels/sec
GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
	Difference: 2600 (10%)

Pixel Rate

The Radeon R9 M270X is a lot (about 76%) better at FSAA than the GeForce 9600 GSO ASUS 512, and also should be capable of handling higher screen resolutions better. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 5000 (76%)

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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
