GeForce 810M vs Radeon HD 4550 512MB

Intro

Compare all of that to the Radeon HD 4550 512MB, which features a core clock speed of 600 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 4550 512MB		25 Watts
	Difference: 10 Watts (67%)

Memory Bandwidth

Performance-wise, the GeForce 810M should in theory be just a bit superior to the Radeon HD 4550 512MB overall. (explain)

GeForce 810M		14400 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 810M should be a lot (approximately 23%) faster with regards to texture filtering than the Radeon HD 4550 512MB. (explain)

GeForce 810M		5904 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 1104 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 810M is superior to the Radeon HD 4550 512MB, and very much so. (explain)

GeForce 810M		2952 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 552 (23%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
