GeForce 820M vs Radeon R7 M260

Intro

The GeForce 820M has core speeds of 719 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.

Compare all that to the Radeon R7 M260, which features GPU core speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R7 M260 should be quite a bit (approximately 49%) faster with regards to AF than the GeForce 820M. (explain)

Radeon R7 M260 17160 Mtexels/sec
GeForce 820M 11504 Mtexels/sec
Difference: 5656 (49%)

Pixel Rate

The Radeon R7 M260 is much (approximately 99%) better at FSAA than the GeForce 820M, and capable of handling higher resolutions while still performing well. (explain)

Radeon R7 M260 5720 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 2844 (99%)

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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
