Radeon HD 6970 vs Radeon R5 M330

Intro

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

Radeon R5 M330		14400 MB/sec
	Difference: 161600 (1122%)

Texel Rate

The Radeon HD 6970 will be a lot (about 310%) faster with regards to texture filtering than the Radeon R5 M330. (explain)

Radeon HD 6970		84480 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 63880 (310%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6970 is superior to the Radeon R5 M330, by far. (explain)

Radeon HD 6970		28160 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 19920 (242%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
