GeForce GTX 950M vs Radeon HD 5550

Intro

Compare those specifications to the Radeon HD 5550, which has core clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 5550		12800 MB/sec
	Difference: 19200 (150%)

Texel Rate

The GeForce GTX 950M should be much (approximately 315%) faster with regards to AF than the Radeon HD 5550. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 27760 (315%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is superior to the Radeon HD 5550, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 10224 (232%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
