GeForce GTX 950M vs Radeon HD 4350

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 950M		55 Watts
	Difference: 33 Watts (150%)

Memory Bandwidth

Performance-wise, the GeForce GTX 950M should in theory be a lot better than the Radeon HD 4350 overall. (explain)

GeForce GTX 950M		32000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 24000 (300%)

Texel Rate

The GeForce GTX 950M should be quite a bit (approximately 695%) faster with regards to AF than the Radeon HD 4350. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 31960 (695%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is the winner, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 12324 (536%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
