VS

GeForce 820M vs Radeon R7 M360

Intro

The GeForce 820M comes with a core clock frequency of 719 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Compare those specifications to the Radeon R7 M360, which has a clock frequency of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon R7 M360 should be quite a bit (approximately 135%) faster with regards to anisotropic filtering than the GeForce 820M. (explain)

Radeon R7 M360 27000 Mtexels/sec
GeForce 820M 11504 Mtexels/sec
Difference: 15496 (135%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 M360 is the winner, by a large margin. (explain)

Radeon R7 M360 9000 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 6124 (213%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
