GeForce 830M vs Radeon R7 M260

Intro

The GeForce 830M comes with a core clock speed of 1029 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is comprised of 256 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 will 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 will be just a 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 using a high resolution is important to you, then the GeForce 830M is the winner, by far. (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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 processed in one second. This figure is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
