GeForce 830M vs Radeon HD 5550

Intro

The GeForce 830M features a GPU core clock speed of 1029 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also features 256 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the Radeon HD 5550, which features GPU core speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 16 Texture Address Units, and 8 ROPs.

GeForce 830M 14400 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 830M will be much (approximately 87%) faster with regards to AF than the Radeon HD 5550. (explain)

GeForce 830M 16464 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 7664 (87%)

Pixel Rate

The GeForce 830M will be a lot (about 87%) better at anti-aliasing than the Radeon HD 5550, and will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 830M 8232 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 3832 (87%)

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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
