GeForce 930M vs Radeon R7 240

Intro

Compare all that to the Radeon R7 240, which features a clock frequency of 730 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 240 should be 100% faster than the GeForce 930M overall, due to its higher data rate. (explain)

Radeon R7 240		28800 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce 930M should be quite a bit (more or less 53%) more effective at texture filtering than the Radeon R7 240. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 7672 (53%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 930M is a better choice, by far. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 1584 (27%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
