GeForce GT 210 vs Radeon HD 4550 512MB

Intro

Compare all of that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR3 memory runs at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 512MB		25 Watts
GeForce GT 210		31 Watts
	Difference: 6 Watts (24%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon HD 4550 512MB should be a bit (approximately 2%) better at texture filtering than the GeForce GT 210. (explain)

Radeon HD 4550 512MB		4800 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 88 (2%)

Pixel Rate

The Radeon HD 4550 512MB should be a small bit (about 2%) more effective at anti-aliasing than the GeForce GT 210, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 4550 512MB		2400 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 44 (2%)

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 MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
