GeForce 9600 GT 512MB vs Radeon R9 M265X

Intro

Compare those specifications to the Radeon R9 M265X, which features a core clock frequency of 575 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 made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M265X is 25% quicker than the GeForce 9600 GT 512MB in general, because of its higher bandwidth. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M265X should be a small bit (about 11%) faster with regards to AF than the GeForce 9600 GT 512MB. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 2200 (11%)

Pixel Rate

The GeForce 9600 GT 512MB should be just a bit (more or less 13%) faster with regards to anti-aliasing than the Radeon R9 M265X, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 1200 (13%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its 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 card's 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 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.
