GeForce 830M vs Radeon HD 4350

Intro

Compare those specifications to the Radeon HD 4350, which features a core clock frequency of 575 MHz and a DDR2 memory speed of 500 MHz. It also features a 64-bit memory bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce 830M		25 Watts
	Difference: 3 Watts (14%)

Memory Bandwidth

The GeForce 830M, in theory, should perform a lot faster than the Radeon HD 4350 overall. (explain)

GeForce 830M		14400 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 6400 (80%)

Texel Rate

The GeForce 830M should be a lot (more or less 258%) faster with regards to AF than the Radeon HD 4350. (explain)

GeForce 830M		16464 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 11864 (258%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 830M is a better choice, and very much so. (explain)

GeForce 830M		8232 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 5932 (258%)

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 max amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record 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 core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
