GeForce 9600 GT 512MB vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X should perform a lot faster than the GeForce 9600 GT 512MB overall. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9600 GT 512MB		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 512MB. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9600 GT 512MB is a better choice, not by a very large margin though. (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: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
