GeForce 820M vs Radeon R7 M260

Intro

The GeForce 820M features a clock speed of 719 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the Radeon R7 M260, which makes use of a 28 nm design. AMD has clocked the core speed at 715 MHz. The DDR3 memory works at a speed of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M260 is a lot (more or less 49%) more effective at AF than the GeForce 820M. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 M260 is superior to the GeForce 820M, by a large margin. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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