GeForce 930M vs Radeon HD 5450

Intro

Compare those specifications to the Radeon HD 5450, which has a core clock frequency of 650 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 930M should theoretically be a little bit better than the Radeon HD 5450 in general. (explain)

GeForce 930M		14400 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be much (more or less 328%) better at anisotropic filtering than the Radeon HD 5450. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 17072 (328%)

Pixel Rate

The GeForce 930M will be quite a bit (about 186%) better at AA than the Radeon HD 5450, and capable of handling higher screen resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 4824 (186%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated 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 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 maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
