GeForce 930M vs Radeon HD 7790

Intro

The GeForce 930M uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The DDR3 RAM works at a speed of 900 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 7790, which has core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 1024 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 7790 should be quite a bit faster than the GeForce 930M overall. (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 (about 151%) better at anisotropic filtering than the GeForce 930M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 7790 is superior to the GeForce 930M, 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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 max fill rate.
