GeForce 830M vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which uses a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260 will be 11% quicker than the GeForce 830M overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon R7 M260 should be a bit (approximately 4%) more effective at AF than the GeForce 830M. (explain)

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

Pixel Rate

The GeForce 830M is quite a bit (approximately 44%) more effective at AA than the Radeon R7 M260, and also should be capable of handling higher resolutions better. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
