GeForce GTX 950M vs Radeon HD 3650 512MB

Intro

Compare those specs to the Radeon HD 3650 512MB, which makes use of a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR3 memory is set to run at a frequency of 800 MHz on this specific card. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Radeon HD 3650 512MB		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The GeForce GTX 950M should be a lot (about 530%) more effective at anisotropic filtering than the Radeon HD 3650 512MB. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 30760 (530%)

Pixel Rate

The GeForce GTX 950M is quite a bit (about 404%) more effective at FSAA than the Radeon HD 3650 512MB, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 11724 (404%)

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 (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
