Radeon HD 5970 vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Radeon R5 M330		14400 MB/sec
	Difference: 241600 (1678%)

Texel Rate

The Radeon HD 5970 should be a lot (about 1026%) more effective at AF than the Radeon R5 M330. (explain)

Radeon HD 5970		232000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 211400 (1026%)

Pixel Rate

The Radeon HD 5970 will be a lot (approximately 1026%) better at anti-aliasing than the Radeon R5 M330, and also should be able to handle higher screen resolutions better. (explain)

Radeon HD 5970		92800 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 84560 (1026%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
