GeForce 820M vs Radeon R7 M360

Intro

Compare those specs to the Radeon R7 M360, which comes with a core clock frequency of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M360 is much (about 135%) more effective at texture filtering 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 should be quite a bit (about 213%) faster with regards to full screen anti-aliasing than the GeForce 820M, and 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
