GeForce 940M vs Radeon R5 M330

Intro

The GeForce 940M comes with a GPU core speed of 1072 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Compare all of that to the Radeon R5 M330, which has a core clock frequency of 1030 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 940M should be 11% quicker than the Radeon R5 M330 in general, because of its greater data rate. (explain)

GeForce 940M 16000 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 940M will be much (more or less 25%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce 940M 25728 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 5128 (25%)

Pixel Rate

The GeForce 940M is a bit (more or less 4%) faster with regards to FSAA than the Radeon R5 M330, and also able to handle higher resolutions better. (explain)

GeForce 940M 8576 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 336 (4%)

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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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