GeForce 820M vs Radeon HD 5550

Intro

The GeForce 820M features a core clock frequency of 719 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and uses a 28 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the Radeon HD 5550, which makes use of a 40 nm design. AMD has set the core speed at 550 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 820M should be quite a bit faster than the Radeon HD 5550 in general. (explain)

GeForce 820M 16000 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The GeForce 820M will be a lot (more or less 31%) better at texture filtering than the Radeon HD 5550. (explain)

GeForce 820M 11504 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 2704 (31%)

Pixel Rate

The Radeon HD 5550 should be much (more or less 53%) more effective at anti-aliasing than the GeForce 820M, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 5550 4400 Mpixels/sec
GeForce 820M 2876 Mpixels/sec
Difference: 1524 (53%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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