GeForce GT 240 GDDR5 vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should theoretically be much better than the GeForce GT 240 GDDR5 in general. (explain)

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

Texel Rate

The Radeon R9 M370X is much (about 82%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)

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

Pixel Rate

The Radeon R9 M370X is a lot (approximately 191%) more effective at AA than the GeForce GT 240 GDDR5, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GT 240 GDDR5		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 (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
