The SAPPHIRE HD 3850 512MB GDDR3 PCI-E is the proud possessor of 666 million transisters and a 256-bit GDDR3 memory interface. Fully distributed design with an internal ring bus for reads and writes of memory, it’s Unified Super scaler Shader Architecture gives you the best in image quality and color.
With Dynamic load balancing and resource allocation for vertex, geometry and pixel shaders, it features a high performance vertex cache and programmable tesselation unit and shader paths that are accelerated for geometry amplification.
Improved stream and output performance has been enhanced by memory read/write caching.
Multi sample anti aliasing is just one of the anti aliasing features that are offer along with us to 24x custom filter.
Offering high definition playback of HD DVD as well as Blu Ray, it also features MPEG 1 and 2 and DIvX decoding acceleration.

Conclusioni Le due nuove schede Sapphire Radeon HD 3850 e HD 3870 mostrano un rapporto prestazioni per prezzo davvero interessante. In media potremmo collocare il modello Radeon HD 3850 alla stregua delle GeForce 8800GTS 320MB: a differenza di queste ultime, però, il suo prezzo è decisamente inferiore, pari a circa 150 Euro. Lo stesso vale anche per il modello Radeon HD 3870 che costa circa 200 Euro. In questo caso le sue prestazioni sono mediamen... Read more
Overall the combination of 5% faster core clock and 768 MB of additional memory can yield a performance improvement of about 10% when comparing Sapphire's HD 3850 1 GB to the HD 3850 with 256 MB. In my opinion this is not worth the price premium of $50. The gains get progressively bigger the higher your resolution and the more eye candy you have turned on. However, you also have to consider that at some point the raw GPU power of the card will reach a limit where more... Read more
The pre-overclocked speeds of the Atomic HD 3870 provided a small boost to our gaming frame rates, as expected. We found we could continue to push the envelope by overclocking, however, and ending up hitting 865 MHz for the GPU - nearly 90 MHz over the default of 777 MHz. While this did add even more performance in our gaming suite, we still couldn't catch up to NVIDIA's latest card, the 8800 GTS 512. At under just $300 though, the Sapphire Atomic HD 3870 is still ...

While there have been many developments in the graphics card market since the ATI Radeon HD3850 was released, it still remains a viable option for those who don't care to layout the kind of money the truly high end cards command. By taking the decent features and specifications this GPU offers on its own and enhancing it with a few tweaks here and there, Sapphire just might be able to deliver on the marketing hype found on the box... "Delivering mayhem to the mainstre... Read more
I’ve been reporting on Sapphire video cards for years now and have yet to find one that doesn’t find some way of leaving a good impression. Sure they’re ATI exclusive, but at this point in hardware history that’s not really a bad place to be with the RV670-class GPUs offering excellent value. Read more
