GeForce 830M vs Radeon R7 M260

Intro

The GeForce 830M makes use of a 28 nm design. nVidia has set the core speed at 1029 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 256 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specifications to the Radeon R7 M260, which comes with GPU clock speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 should be 11% quicker than the GeForce 830M overall, due to its higher bandwidth. (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%) better at texture filtering than the GeForce 830M. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 830M is a better choice, by a large margin. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
