GeForce 920M vs Radeon R5 M330

Intro

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

Compare those specs to the Radeon R5 M330, which comes with a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The GeForce 920M should be much (more or less 48%) faster with regards to AF than the Radeon R5 M330. (explain)

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

Pixel Rate

The Radeon R5 M330 should be a small bit (more or less 8%) more effective at AA than the GeForce 920M, and also will be capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 that the graphics chip 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 number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
