GeForce 930M vs Radeon HD 6870

Intro

Compare those specifications to the Radeon HD 6870, which makes use of a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this specific card. It features 1120 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6870 should be 833% quicker than the GeForce 930M in general, due to its higher data rate. (explain)

Radeon HD 6870		134400 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 120000 (833%)

Texel Rate

The Radeon HD 6870 will be a lot (about 126%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)

Radeon HD 6870		50400 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 28128 (126%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6870 is the winner, and very much so. (explain)

Radeon HD 6870		28800 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 21376 (288%)

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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be processed per 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 this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
