The first information about Radeon HD 3800

Release date next generation of processors that AMD phenom, for desktops, as well as next-generation RV670 graphics processor, is initially appointed on 19 November 2007.
The phenom and RD790 looks closed. The elder brother phenom, a server-based Barcelona, met with an average response.

Radeon HD 3800, previously determined code name of RV670, was slightly larger riddle, at least for this weekend. AMD publicly announced that RV670 will be produced using a new process, which entails a change in the 80 nanometer Radeon HD 2900 (R600) at 55 nanometers.

Information, which have proceeded in the past week also describe the superiority of DirectX 10.1 performed by AMD. As it usually happens with przeciekami, which take place just before the premiere of competing products, in this case on NVIDIA GeForce 8800GT, exchange unlikely to improve efficiency.

Another component, which appeared this week, comes from the website of the company Diamond Multimedia. From there you can read the details of the three new Radeon graphics cards: weakest, highendowej GDDR3 and highendowej GDDR4. Google and its archive will help get the relevant information about this offer.

Radeon HD 3850 will be equipped with only 256MB of GDDR3 working with a frequency of 825 MHz. Core was set at 660 MHz.

Slightly better Radeon HD 3870 will be accompanied by a memory instead of GDDR3 and GDDR4 will use the same core, which is in HD 3850. GDDR4 memory is strong with a frequency of 1.2 GHz, a frequency core podkręcono to 775 MHz.
HD 3870 version is equipped with GDDR3 will have the same frequency as the core papers in the case of GDDR4. As a result of GDDR3 memory card with a lower frequency will be directed to customers who want to spend on purchases slightly less money.

Interestingly, according to the ad Radeon HD 3850 is the same specification as 80 nanometrowy Radeon HD 2900. The only exception is the use of GDDR3 memory. Thermal envelope in the case of HD 3850 will be lower as compared to the previous generation, but performance will be maintained at the level Radeon HD 2900.

On the other hand, the Radeon HD 3870 is an example of an ambitious progress in relation to the previous generation. A strong core is now more than 100 MHz faster, reaching 775 MHz and the memory has gained an additional 400 MHz compared to GDDR4 in R600.

As is clear from the information, which ATI has given the producers, they will be able to freely decide on the frequency and timing of memory core, so that each company will provide a minimum of otherwise strong products.

Among other noteworthy features RV670 was handling Quad Crossfire and AMD Triple Play physics.

Radeon HD 2900 XT caused confusion when it became clear that it will not, as advertised, equipped with a Universal Video Decoder. Manufacturers forming Radeon cards were not able to confirm whether the decoder is fitted RV670, despite the fact that the R600 speak to the fact that the power of calculation is so large that he does not need HD hardware accelerator. The situation may repeat in the event of the RV670.

Prices RV670 not yet been confirmed. However, taking into account that the Radeon HD 3850 is basically a Radeon HD 2900, you can easily predict that these cards are valued similarly to the current R600 series.
