GeForce 920M vs Radeon HD 4350

Intro

Compare all that to the Radeon HD 4350, which comes with a core clock frequency of 575 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 64-bit memory bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 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 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce 920M will be much (about 564%) faster with regards to texture filtering than the Radeon HD 4350. (explain)

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

Pixel Rate

The GeForce 920M should be a lot (more or less 232%) faster with regards to full screen anti-aliasing than the Radeon HD 4350, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
