GeForce GTX 560 Ti vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which comes with GPU clock speed of 1030 MHz, and 2048 MB of DDR3 memory 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.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 560 Ti should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 113856 (791%)

Texel Rate

The GeForce GTX 560 Ti is quite a bit (about 155%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 32008 (155%)

Pixel Rate

The GeForce GTX 560 Ti is quite a bit (more or less 219%) more effective at full screen anti-aliasing than the Radeon R5 M330, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 18064 (219%)

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 (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
