GeForce 930M vs Radeon HD 5550

Intro

The GeForce 930M has a core clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the Radeon HD 5550, which features GPU clock speed of 550 MHz, and 512 MB of DDR2 memory set to run at 400 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 930M should be just a bit faster than the Radeon HD 5550 in general. (explain)

GeForce 930M 14400 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be much (approximately 153%) better at AF than the Radeon HD 5550. (explain)

GeForce 930M 22272 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 13472 (153%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 930M is a better choice, and very much so. (explain)

GeForce 930M 7424 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 3024 (69%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
