Radeon HD 6670 (OEM) vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which comes with a core clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The Radeon R5 M330 will be a small bit (about 7%) more effective at texture filtering than the Radeon HD 6670 (OEM). (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 6670 (OEM)		19200 Mtexels/sec
	Difference: 1400 (7%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M330 is a better choice, and very much so. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec
	Difference: 1840 (29%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
