GeForce 930M vs Radeon HD 4550 512MB

Intro

Compare all of that to the Radeon HD 4550 512MB, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 930M will be 13% faster than the Radeon HD 4550 512MB in general, because of its greater data rate. (explain)

GeForce 930M		14400 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be much (approximately 364%) faster with regards to texture filtering than the Radeon HD 4550 512MB. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 17472 (364%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 930M is the winner, and very much so. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 5024 (209%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
