GeForce GTX 960M vs Radeon HD 5450

Intro

Compare those specs to the Radeon HD 5450, which features core speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 38640 (743%)

Pixel Rate

The GeForce GTX 960M should be much (more or less 574%) more effective at full screen anti-aliasing than the Radeon HD 5450, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 14936 (574%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
