GeForce 830M vs Radeon R7 260X

Intro

The GeForce 830M uses a 28 nm design. nVidia has clocked the core speed at 1029 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this model. It features 256 SPUs along with 16 TAUs and 8 ROPs.

Compare that to the Radeon R7 260X, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1625 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M 25 Watts
Radeon R7 260X 115 Watts
Difference: 90 Watts (360%)

Memory Bandwidth

In theory, the Radeon R7 260X will be 622% faster than the GeForce 830M in general, due to its greater bandwidth. (explain)

Radeon R7 260X 104000 MB/sec
GeForce 830M 14400 MB/sec
Difference: 89600 (622%)

Texel Rate

The Radeon R7 260X is quite a bit (more or less 274%) faster with regards to AF than the GeForce 830M. (explain)

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

Pixel Rate

The Radeon R7 260X should be much (more or less 114%) faster with regards to FSAA than the GeForce 830M, and also should be capable of handling higher resolutions without slowing down too much. (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 max amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must 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 AA, High Dynamic Range and high resolutions.

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

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