GeForce GT 240 GDDR5 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should in theory be much superior to the GeForce GT 240 GDDR5 overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 17600 (32%)

Texel Rate

The Radeon R9 M365X will be a lot (approximately 110%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 19400 (110%)

Pixel Rate

The Radeon R9 M365X will be much (more or less 236%) faster with regards to AA than the GeForce GT 240 GDDR5, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 10400 (236%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
