Radeon HD 6850 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which features core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 6850 should in theory be much better than the Radeon R5 M330 in general. (explain)

Radeon HD 6850		128000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 6850 is quite a bit (more or less 81%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon HD 6850		37200 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 16600 (81%)

Pixel Rate

The Radeon HD 6850 is quite a bit (more or less 201%) faster with regards to AA than the Radeon R5 M330, and able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 6850		24800 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 16560 (201%)

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 information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
