GeForce 820M vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 RAM works at a speed of 1000 MHz on this card. It features 384 SPUs as well as 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 M260 will be quite a bit (approximately 49%) better at AF than the GeForce 820M. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 820M		11504 Mtexels/sec
	Difference: 5656 (49%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M260 is a better choice, by a large margin. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce 820M		2876 Mpixels/sec
	Difference: 2844 (99%)

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 MB per second) that can be moved across 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 RAM, the result 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
