GeForce 830M vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with a clock frequency of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260 should theoretically be a bit superior to the GeForce 830M overall. (explain)

Radeon R7 M260		16000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R7 M260 should be a little bit (about 4%) faster with regards to AF than the GeForce 830M. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 696 (4%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 830M is a better choice, and very much so. (explain)

GeForce 830M		8232 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 2512 (44%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
