GeForce 9600 GSO 512MB vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which has a core clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M265X should be quite a bit faster than the GeForce 9600 GSO 512MB in general. (explain)

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

Texel Rate

The GeForce 9600 GSO 512MB should be quite a bit (about 36%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 8200 (36%)

Pixel Rate

The GeForce 9600 GSO 512MB will be a little bit (approximately 13%) more effective at anti-aliasing than the Radeon R9 M265X, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 9600 GSO 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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
