HD 6870 and HD 6850 from Different Vendors Reviewed.

As we all know that the HD 6800 Series has been released today and benchmarked too on different sites. So let's do a review on how good do these card perform over the Nvidia's Fermi based GPU's and the older 5800 series. Well, The card are based on the Barts core and both are built on a 40Nm Process. The 6870 holds 1120 Stream processors while the 6850 holds a total of 960 stream processors. The 6870 is clocked at 900 MHz core and 1050 MHz memory (4200 MHz GDDR5 effective) while 6850 is at 775 MHz core and 1000 MHz memory. Both the cards feature AMD exclusive features such as the 3rd generation Unified Video Decoder (UVD 3.0), which provides GPU acceleration for Blu-ray 3D and DivX high-definition video formats, and six display controllers offering six TMDS links. The display connectors on both cards include two DVI, one HDMI 1.4a, and two mini-DisplayPort 1.2 connectors. The HDMI 1.4 is also a new thing to be seen on the 6800 series cards. Pricing of both the cards can be seen here.

Both cards hold 1GB of GDDR5 memory along a 256-bit wide memory interface. The power maximum power consumption of the 6850 is around 129w compared to the GTX 460's 1Gb 155W while the 6870 consumes 163W. The power consumption of the cards are much lower than its predecessor. The temps are also good for the 6850 which are around 34 at idle and 75C at load while 6870's are a bit more at 42 on idle and 88C at load. Both the cards feature Voltage tuning which means overclocking can be quite easy with them and they are already great overclockers as the 6870 reaches a clock of 1050 with a few voltage adjustments while the 6850 goes beyond 900Mhz with overclocking.

Performance of the cards over the Older generation has increased but we cant say much. the pricing is something which makes them a great buy. As seen in Dx11 benchmarks, These cards still lack in tessellation as compared with the Fermi cards. But noticeable difference over the 5800 series can be seen. Other benchmarks are in more favor of these cards. The 6850 takes the lead on GTX 460 but with a difference of only 3-6 FPS. While the 6870 is doing a good job blowing away the GTX 470 in most of the benchmarks. The recent price cuts by nvidia has made more competition between these two competitors. Another thing to notice here is that the Crossfire performance has vastly been improved in the new cards as from the benchies the 6850 crossfired are performing better than the SLI'd 460's while the 470's are also taking a huge blow from the 6870's x2. AMD has done a good job by introducing these cards but Nvidia is also reading its upcoming geforce 500 series based cards codenamed the GTX 80 and GTX 560 which are speculated to perform 20-30% better than its current gen fermi cards. These cards will be released by the end of this year or early next year. You can check them out here.
