GeForce 930M vs Radeon HD 5770

Intro

The GeForce 930M features a GPU core clock speed of 928 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the Radeon HD 5770, which uses a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this specific model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5770 should theoretically be much better than the GeForce 930M in general. (explain)

Radeon HD 5770 76800 MB/sec
GeForce 930M 14400 MB/sec
Difference: 62400 (433%)

Texel Rate

The Radeon HD 5770 should be quite a bit (more or less 53%) more effective at texture filtering than the GeForce 930M. (explain)

Radeon HD 5770 34000 Mtexels/sec
GeForce 930M 22272 Mtexels/sec
Difference: 11728 (53%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5770 is superior to the GeForce 930M, by far. (explain)

Radeon HD 5770 13600 Mpixels/sec
GeForce 930M 7424 Mpixels/sec
Difference: 6176 (83%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
