GeForce 920M vs Radeon R5 M330

Intro

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

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce 920M should be a lot (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 is a little bit (approximately 8%) faster with regards to AA than the GeForce 920M, and able to handle higher resolutions better. (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 (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
