GeForce GT 240 GDDR5 vs Radeon R9 M270X

Intro

Compare that to the Radeon R9 M270X, which features a GPU core clock speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M270X should in theory be a lot better than the GeForce GT 240 GDDR5 in general. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M270X is quite a bit (more or less 65%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R9 M270X		29000 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 11400 (65%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M270X is a better choice, and very much so. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 7200 (164%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is worked out 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 ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
