GeForce 930M vs Radeon HD 7790

Intro

Compare those specs to the Radeon HD 7790, which has GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 7790 should be quite a bit faster than the GeForce 930M in general. (explain)

Radeon HD 7790		96000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 81600 (567%)

Texel Rate

The Radeon HD 7790 should be a lot (more or less 151%) better at AF than the GeForce 930M. (explain)

Radeon HD 7790		56000 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 33728 (151%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 7790 is the winner, and very much so. (explain)

Radeon HD 7790		16000 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8576 (116%)

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 max amount of data (in units of MB per second) that can be moved over 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 memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated 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 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 maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
