GeForce 820M vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which makes use of a 28 nm design. AMD has set the core frequency at 1125 MHz. The DDR3 RAM works at a speed of 1000 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator 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 Radeon R7 M360 is much (about 135%) faster with regards to AF than the GeForce 820M. (explain)

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

Pixel Rate

The Radeon R7 M360 will be quite a bit (more or less 213%) faster with regards to full screen anti-aliasing than the GeForce 820M, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
