Compare any two graphics cards:
VS

GeForce 920M vs Radeon R5 M330

Intro

The GeForce 920M comes with a core clock speed of 954 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare all that to the Radeon R5 M330, which features core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce 920M should be quite a bit (about 48%) faster with regards to anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 920M 30528 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 9928 (48%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R5 M330 is a better choice, though only just barely. (explain)

Radeon R5 M330 8240 Mpixels/sec
GeForce 920M 7632 Mpixels/sec
Difference: 608 (8%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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