GeForce 930M vs Radeon HD 5550

Intro

Compare all of that to the Radeon HD 5550, which features core clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 930M should be 13% faster than the Radeon HD 5550 in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 930M is a lot (more or less 153%) faster with regards to AF than the Radeon HD 5550. (explain)

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

Pixel Rate

The GeForce 930M is a lot (about 69%) faster with regards to anti-aliasing than the Radeon HD 5550, and also should be able to handle higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
