GeForce GTX 560 Ti 448 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which has GPU clock speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 ROPs.

	Difference: 20392 (99%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be a lot (more or less 255%) better at anti-aliasing than the Radeon R5 M330, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 21040 (255%)

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: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
