GeForce 810M vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which has clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 is 567% quicker than the GeForce 810M overall, due to its greater data rate. (explain)

Radeon R9 M380		96000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 81600 (567%)

Texel Rate

The Radeon R9 M380 should be a lot (approximately 578%) more effective at AF than the GeForce 810M. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 34096 (578%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M380 is superior to the GeForce 810M, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 13048 (442%)

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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
