GeForce 830M vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core frequency at 725 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 is 122% faster than the GeForce 830M in general, due to its greater bandwidth. (explain)

Radeon R7 M265		32000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The Radeon R7 M265 will be just a bit (more or less 6%) faster with regards to texture filtering than the GeForce 830M. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 936 (6%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 830M is superior to the Radeon R7 M265, and very much so. (explain)

GeForce 830M		8232 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 2432 (42%)

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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. 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 card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
