GeForce GTX 870M vs Radeon HD 4350

Intro

Compare all that to the Radeon HD 4350, which features GPU clock speed of 575 MHz, and 512 MB of DDR2 RAM set to run at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 100792 (2191%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 870M is superior to the Radeon HD 4350, by a large margin. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 20284 (882%)

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 megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
