GeForce 920M vs Radeon HD 5670

Intro

Compare those specs to the Radeon HD 5670, which makes use of a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5670 should in theory be a lot superior to the GeForce 920M overall. (explain)

Radeon HD 5670		64000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce 920M is a lot (about 97%) faster with regards to AF than the Radeon HD 5670. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 15028 (97%)

Pixel Rate

The GeForce 920M is a lot (more or less 23%) better at full screen anti-aliasing than the Radeon HD 5670, and able to handle higher resolutions while still performing well. (explain)

GeForce 920M		7632 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 1432 (23%)

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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the graphics card 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 Raster Operations Pipelines 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
