GeForce GTX 870M vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which makes use of a 55 nm design. AMD has clocked the core speed at 575 MHz. The DDR2 RAM works at a speed of 500 MHz on this particular card. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 870M		110 Watts
	Difference: 88 Watts (400%)

Memory Bandwidth

Performance-wise, the GeForce GTX 870M should in theory be a lot superior to the Radeon HD 4350 overall. (explain)

GeForce GTX 870M		96000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 88000 (1100%)

Texel Rate

The GeForce GTX 870M should be a lot (more or less 2191%) faster with regards to anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 100792 (2191%)

Pixel Rate

The GeForce GTX 870M is quite a bit (approximately 882%) more effective at FSAA than the Radeon HD 4350, and also able to handle higher screen resolutions while still performing well. (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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
