GeForce 820M vs Radeon R7 M360

Intro

Compare those specs to the Radeon R7 M360, which makes use of a 28 nm design. AMD has set the core speed at 1125 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

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 M360 should be a lot (about 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 running with a high resolution is important to you, then the Radeon R7 M360 is superior to the GeForce 820M, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the 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 better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
