GeForce 9600 GSO 384MB vs Radeon R9 M270X

Intro

Compare all of that to the Radeon R9 M270X, which comes with GPU core speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X will be 88% quicker than the GeForce 9600 GSO 384MB in general, due to its higher bandwidth. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M270X should be just a bit (more or less 10%) better at anisotropic filtering than the GeForce 9600 GSO 384MB. (explain)

Radeon R9 M270X		29000 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 2600 (10%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M270X is superior to the GeForce 9600 GSO 384MB, and very much so. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce 9600 GSO 384MB		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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of 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 higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
