GeForce 940M vs Radeon R5 M230

Intro

The GeForce 940M comes with a GPU core speed of 1072 MHz, and the 2048 MB of DDR3 memory is set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Compare those specs to the Radeon R5 M230, which features GPU clock speed of 780 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce 940M should be a lot (more or less 65%) better at AF than the Radeon R5 M230. (explain)

GeForce 940M 25728 Mtexels/sec
Radeon R5 M230 15600 Mtexels/sec
Difference: 10128 (65%)

Pixel Rate

The GeForce 940M is quite a bit (approximately 175%) better at AA than the Radeon R5 M230, and also capable of handling higher resolutions more effectively. (explain)

GeForce 940M 8576 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 5456 (175%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card 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 amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
