GeForce 920M vs Radeon HD 5550

Intro

The GeForce 920M makes use of a 28 nm design. nVidia has set the core speed at 954 MHz. The DDR3 memory runs at a frequency of 900 MHz on this specific card. It features 384 SPUs as well as 32 TAUs and 8 ROPs.

Compare those specifications to the Radeon HD 5550, which has a GPU core clock speed of 550 MHz, and 512 MB of DDR2 memory running at 400 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 920M should theoretically be a small bit superior to the Radeon HD 5550 overall. (explain)

GeForce 920M 14400 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 920M will be a lot (about 247%) better at texture filtering than the Radeon HD 5550. (explain)

GeForce 920M 30528 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 21728 (247%)

Pixel Rate

The GeForce 920M will be much (more or less 73%) faster with regards to full screen anti-aliasing than the Radeon HD 5550, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 920M 7632 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 3232 (73%)

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 MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
