GeForce 930M vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which has a core clock speed of 575 MHz and a DDR2 memory speed of 500 MHz. It also features a 64-bit memory bus, and makes use of a 55 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 17672 (384%)

Pixel Rate

The GeForce 930M should be a lot (approximately 223%) faster with regards to anti-aliasing than the Radeon HD 4350, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 5124 (223%)

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 MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
