GeForce 920M vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which comes with core clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 920M is 80% quicker than the Radeon HD 4350 in general, because of its higher data rate. (explain)

GeForce 920M		14400 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 6400 (80%)

Texel Rate

The GeForce 920M should be much (more or less 564%) faster with regards to anisotropic filtering than the Radeon HD 4350. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 25928 (564%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 920M is the winner, by far. (explain)

GeForce 920M		7632 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 5332 (232%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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