GeForce 830M vs Radeon HD 4550 256MB

Intro

The GeForce 830M features a GPU core 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 is made up of 256 Stream Processors, 16 TAUs, and 8 ROPs.

Compare all that to the Radeon HD 4550 256MB, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The DDR3 memory runs at a frequency 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

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce 830M should perform a small bit faster than the Radeon HD 4550 256MB in general. (explain)

GeForce 830M 14400 MB/sec
Radeon HD 4550 256MB 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 830M should be a lot (about 243%) more effective at AF than the Radeon HD 4550 256MB. (explain)

GeForce 830M 16464 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 11664 (243%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 830M is a better choice, by far. (explain)

GeForce 830M 8232 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 5832 (243%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
