GeForce 810M vs Radeon HD 4550 256MB

Intro

Compare all that to the Radeon HD 4550 256MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 600 MHz. The DDR3 RAM works at a speed of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Pixel Rate

The GeForce 810M will be a lot (more or less 23%) faster with regards to AA than the Radeon HD 4550 256MB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 810M		2952 Mpixels/sec
Radeon HD 4550 256MB		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 data (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
