quick test:radeon hd 3850 ddr2 crossfire vs. radeon hd 4850   Since the advent of on the shelves of graphic solutions Radeon HD 3850 has passed more than a year. It would seem that long ago, all tested, measured, and asked readers for their information. However, in our laboratories into two interesting video, made on the basis of GPU RV670. Products Sapphire is interesting that the memory is completed with a standard DDR2. A similar decision, we have repeatedly written, but look at what they can do so and did not receive. Now fill this gap and test linkage of the two graphics cards to Sapphire Radeon HD 3850 DDR2 in CrossFire. An opponent will be Radeon HD 4850 accelerator. He was chosen because it is two times more than the Radeon HD 3850 DDR2. We have to determine how profitable to invest money, either as two to $ 80, or as $ 160.
Before you start testing, you should understand the characteristics of the product Sapphire Radeon HD 3850 DDR2 512 Mb, and its accelerating potential, a test stand and a set of applications. So, as already has been said above, the principal features of video cards is installed on its memory DDR2. Memory chips operate at a frequency of 500 MHz, which is considerably lower than 828 MHz at HD 3850 DDR3. Graphic processor operates at a frequency recommended by AMD - 670 MHz.
Other differences from the standard version Radeon HD 3850 does not. The cooling system installed on the Sapphire Radeon HD 3850 DDR2, perfectly copes with its task, and virtually silent. The efficiency of the cooling system was tested using RivaTuner v. 2. 22, and as a tool used to heat multiple run 3DMark 2006.
Acceleration card made with the utility ATI Tray Tools 1. 69. 1374. Using the so-called softvoltmod, managed to disperse the graphics card to 850 MHz on the core. In doing so, instead of voltage, 1 in 014, was billed as far as possible, 1 254 V. The memory was able to get 600 MHz, that is quite so good.
The configuration of test stand is shown in the table.
Output graphics valued in synthetic benchmarks and games:
  • 3DMark03 v3. 6. 0 - 1024x768, NoAA/NoAF;
  • 3DMark05 v1. 2. 0 - 1024x768, NoAA/NoAF;
  • 3DMark06 v1. 0. 2 - 1280x1024, NoAA/NoAF;
  • Crysis v1. 2. 1 - 1280x1024, NoAA/NoAF;
  • Counter-Strike Source v1. 0. 0. 34 - 1280x1024, 4AA/16AF;
  • Nurien Tech Demo v0. 7 - 1024x768, NoAA/NoAF.
be aware of the tests will begin with 3DMark.
In the synthetic everything looks just great. Approximately 10-15% wins a bundle of two Radeon HD 3850 DDR2 with a single Radeon HD 4850. However, synthetics can not see the whole picture.
The first command positions Radeon HD 3850 DDR2 struck Technology shooter Crysis. The difference between the Radeon HD 4850 and Radeon HD 3850 DDR2 CrossFire is 19%. Furthermore, most games in the Radeon HD 4850 graphics card is better stability, while a couple of times to take the picture jumps. Even worse situation in the online game Counter-Strike Source. Provide the difference in percentage terms it makes no sense, graphs show clearly retarded. Only in the Nurien Tech Demo bundle of two Radeon HD 3850 DDR2 managed to get ahead of the decision on the basis of RV770PRO.
Express testing has been completed. The victory for the Radeon HD 4850 is unique. Taking into account the results in 3DMark over need, but as it turned out, in real gaming applications of forces is different. The only incentive for the possession of two Radeon HD 3850 DDR2 is the chance to enter the club CrossFire.
