GeForce GTX 960M vs Radeon HD 5550

Intro

Compare all of that to the Radeon HD 5550, which uses a 40 nm design. AMD has clocked the core speed at 550 MHz. The DDR2 RAM works at a speed of 400 MHz on this specific model. It features 320(64x5) SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960M should be much faster than the Radeon HD 5550 in general. (explain)

GeForce GTX 960M		64000 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 51200 (400%)

Texel Rate

The GeForce GTX 960M should be a lot (approximately 398%) better at anisotropic filtering than the Radeon HD 5550. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 35040 (398%)

Pixel Rate

The GeForce GTX 960M should be quite a bit (more or less 299%) better at full screen anti-aliasing than the Radeon HD 5550, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 13136 (299%)

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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
