GeForce 9600 GT 1GB vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which features a GPU core clock speed of 575 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M265X should perform a lot faster than the GeForce 9600 GT 1GB in general. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M265X will be just a bit (approximately 11%) more effective at AF than the GeForce 9600 GT 1GB. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 2200 (11%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9600 GT 1GB is the winner, not by a very large margin though. (explain)

GeForce 9600 GT 1GB		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 information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be processed 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
