ATI Radeon HD 5850 was top part range which debuted at £ 173 exc VAT. Despite the prize winners, AMD believes that it is something of an aberration, too expensive for most consumers despite its excellent results refer. At only £ 127 exc VAT, the new HD 6850 marked a return to the very important "sweet place."
It is not just less expensive model last year. It also features a redesigned and optimized architecture.The main change concerns arrangement flux.alors HD 5800 maps had a single complex processor with four simple "slaves" swatches processors, AMD has made later with shaders slave completely and rather packed a Quartet of complex cores together.
Even if it means that the HD 6850 is only 960 processor flow 1 600 HD 5850, each string quartet can handle more complex tasks more efficiently. This is a change that AMD hopes will allow his cards to do more with less.
The rest of the HD 6850 is less than a 775 MHz core clock and 5850 HD - classic, with 1.7 billion transistors-400 million.One gigabyte of memory RAM GDDR5 runs to 1 000 MHz, and it has a 256-bit memory bus.
These improvements to some interesting results in our benchmarks of average Crysis.Une 33 FPS in our very high cue point of 1,920 x 1,080 is four frames faster than 1 GB GeForce Nvidia GTX 460;This gap has remained when we activated 4 x anti-aliasing, with a score of 29 fps almost playable.
6850 HD marked 35 FPS in our high-quality test at a higher resolution of 2,560 x 1,600, even if it was the ceiling; when we loaded the same test with higher settings of the Crysis, 6850 HD fought for a score of 21 fps.
Nvidia rivals was slightly in advance according to our tests of dirt 2, however.460 GTX ran through our reference at 1,920 x 1,080 to more than 60 fps maximum quality with 6850 HD 53 fps back.
There is little to worry about when it comes to consumption of heat and electricity, soit.Une 83 degrees maximum temperature is not too high and a draw in our test rig 248W peak power is significantly lower than the equivalent of Nvidia.
The final piece the puzzle of rides AMD is the price, and is the greatest strength of the card £ 127 H. VAT 6850 HD is the same price even faster tests more than 460 GTX.Et when compared to the HD of AMD 6870, small loss in the frame rate is easily made to savings price of nearly $ 50 £ it is somewhat unusual in that the HD 6850 is slower than its predecessor, but the price means that it is probably the most beautiful card rides available.
