GeForce GT 240 GDDR5 vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which has a core clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X is 76% quicker than the GeForce GT 240 GDDR5 in general, because of its higher bandwidth. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 41600 (76%)

Texel Rate

The Radeon R9 M385X will be much (more or less 250%) more effective at anisotropic filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 44000 (250%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M385X is a better choice, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 13200 (300%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few 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.
