GeForce 830M vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which features a clock frequency of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce 830M		14400 MB/sec
	Difference: 89600 (622%)

Texel Rate

The Radeon R7 260X will be much (approximately 274%) better at anisotropic filtering than the GeForce 830M. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 45136 (274%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 260X is a better choice, by a large margin. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 9368 (114%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
