GeForce 830M vs Radeon R7 260X

Intro

The GeForce 830M has a GPU core speed of 1029 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also features 256 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare all of that to the Radeon R7 260X, which comes with a clock frequency of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

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

Texel Rate

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

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 260X is superior to the GeForce 830M, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
