GeForce 830M vs Radeon HD 5550

Intro

The GeForce 830M comes with a core clock frequency of 1029 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 256 SPUs, 16 TAUs, and 8 ROPs.

Compare those specifications 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 works at a speed of 400 MHz on this specific model. It features 320(64x5) SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 830M, in theory, should be a bit faster than the Radeon HD 5550 overall. (explain)

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

Texel Rate

The GeForce 830M will be much (about 87%) faster with regards to texture filtering 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 should be quite a bit (more or less 87%) more effective at FSAA than the Radeon HD 5550, and should be able to handle higher screen resolutions without losing too much performance. (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 data (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
