GeForce GT 240 GDDR5 1GB vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 32% quicker than the GeForce GT 240 GDDR5 1GB overall, because of its greater bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M370X should be much (about 82%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 14400 (82%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M370X is the winner, by far. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 8400 (191%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to get to the maximum fill rate.
