GeForce 920M vs Radeon R5 M230

Intro

The GeForce 920M has a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon R5 M230, which comes with GPU core speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 Texture Address Units, and 4 Raster Operation Units.

In theory, the Radeon R5 M230 will be 11% quicker than the GeForce 920M in general, due to its higher data rate. (explain)

Radeon R5 M230 16000 MB/sec
GeForce 920M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 920M should be much (more or less 96%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

GeForce 920M 30528 Mtexels/sec
Radeon R5 M230 15600 Mtexels/sec
Difference: 14928 (96%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 920M is a better choice, and very much so. (explain)

GeForce 920M 7632 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 4512 (145%)

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 largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 are applied per second. This figure is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the maximum fill rate.
