GeForce GTX 950M vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which features core speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs as well as 8 Texture Address Units 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

In theory, the GeForce GTX 950M will be 300% faster than the Radeon HD 4350 overall, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 950M will be a lot (about 695%) more effective at anisotropic filtering 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 superior to the Radeon HD 4350, and very much so. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
