GeForce 930M vs Radeon HD 5770

Intro

Compare all of that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this particular model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5770 should theoretically be quite a bit superior to 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 is quite a bit (more or less 53%) faster with regards to AF 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, and very much so. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
