TEST/Compare PowerColor HD6850 1GB GDDR5 PREMIUM EDITION
Price per Performance Ratio is one of the most important aspects in choosing a PC's hardware or in the context of these times are in choosing a graphics card.
If you are one of the users who attach great importance to Price per performance, then the wisest choice in choosing a graphics card graphics card found in mainstream classes.
In mainstream classes, the comparison between performance and cost factors into a very sensitive in view of the user. In general, this graphics card that has the efficiency of the best will be selected. As an example one of the AMD ATI graphics card, codenamed Barts we were going to test this product.
Barts divided into two options, namely Barts Pro (HD 6850) and Barts XT (HD 6870). Both sisters have a difference in the specifications, among others, the number of Stream Processors, Texture unit, and also Core / Memory Clock owned. For more specs you can see in the table below:

This time I will test and compare the PowerColor HD 6850 Premium Edition which uses the GPU chip Barts Pro with another graphic card in class. PowerColor Premium Edition provides a name for this graphics card has its own advantages. The advantages include a clock and also because of his memory that was set higher than the reference, or so-called Factory overclocked. PowerColor provide an extra 25 MHz on the core clock who fulfill the score to 800 MHz, and memory clock into 1050 MHz (4200 MHz effective). In addition to a higher specification, PowerColor HD 6850 Premium is equipped with cooling (HSF) 3rd party from Zerotherm, of course, to issues of quality no doubt because the Zerotherm is quite experienced and a specialist in the manufacture of HSF.
Lets see how good it works and see the result of the test..
CRYSIS WARHEAD (Ambush) test:
So, I think this graphic card is good enough to handle games that support Directx 9, 10, 11. With the addition of premium names on this PowerColor graphics card, they can prove that his product HD 6850 does offer something more. With a little additional extra energy in the Core and Memory Clock 800/4200 MHz be able to boost the performance of graphics card is slightly faster than the reference product.Excess
