GeForce 9600 GSO 384MB vs Radeon R9 M270X

Intro

Compare those specs to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M270X should theoretically be quite a bit superior to the GeForce 9600 GSO 384MB in general. (explain)

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

Texel Rate

The Radeon R9 M270X is just a bit (approximately 10%) more effective at AF 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

The Radeon R9 M270X is a lot (about 76%) more effective at full screen anti-aliasing than the GeForce 9600 GSO 384MB, and will be able to handle higher resolutions more effectively. (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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure 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 card will be at 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 could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
