GeForce GT 240 GDDR5 1GB vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which comes with GPU core speed of 575 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should theoretically perform a lot faster than the GeForce GT 240 GDDR5 1GB in general. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M265X should be quite a bit (approximately 31%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 5400 (31%)

Pixel Rate

The Radeon R9 M265X should be much (more or less 109%) more effective at anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also capable of handling higher resolutions better. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 4800 (109%)

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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
