GeForce 830M vs Radeon HD 4350

Intro

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

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 should theoretically be quite a bit 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 will be quite a bit (approximately 258%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

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

Pixel Rate

If running with a high screen resolution 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
