AMD’s newest R680 graphics processor might look a whole lot like the ill-fated R600 GPU, but the reality couldn’t be more bizarre.  Instead of one 80nm behemoth-of-a-GPU, the R680 consists of two 55nm processor cores.

Representatives from AMD would not confirm that the R680 is essentially two RV670 GPU cores on the same board, though the company did confirm that each core has the same specifications of an RV670 processor.

The RV670 graphics core, announced last November with the Phenom processor, is the first 55nm desktop graphics adaptor.  AMD does not target this card as a high-end adaptor, though reviewers were quick to herald the RV670 as AMD’s best product of 2007.

The company also made quick mention of the RV620 and RV635 GPU cores.  These cores are nearly identical to the previous RV610 and RV630 processors, but will be produced on the 55nm node instead. 

All three of AMD’s new GPUs are scheduled to launch next month. 

Dual-GPU technology is not new.  3dfx’s flagship Voodoo 5 family also resorted to multiple processors to achieve its relatively high performance.  ASUS, Gigabyte, Sapphire, HIS and PowerColor all introduced dual-GPU configurations of just about every graphics processor on the market, though these were never “sanctioned” ATI or NVIDIA projects.  Ultimately, all of these projects were canned due to long development times and low demand.

Cross-state rival NVIDIA isn’t sitting on idle hands though, either.   The company publicly announced plans to replace all 90nm G80 graphics cores with G92 derivatives by the end of the year.  G92’s debut introduction, GeForce 8800 GT, met wild support from reviewers and analysts alike.  G92’s second introduce, GeForce 8800 GTS 512MB, was met with similar but less enthusiastic acceptance during Tuesday’s launch.

NVIDIA’s newest roadmap claims the DirectX 10.1 family of 65nm processors will also hit store shelves this Spring.  The chipsets — codenamed D9E, D9M and D9P — are architecturally different from the G80/G92 family.

In recent years, consumers electronics and telecommunication companies had been trying to bring gamers into their mobile phone business. This was done either by implementing games into their mobile devices. Here is a twist to that old convention, Sony had teamed up with Ebay’s Skype division to bring you VOIP on your PSP. It is confirmed that mobiles gamers can now transform their PSP into mobile communication device. PSP owners can download the firmware update as well as an application that allow them to make free PSP to PSP and PSP to PC calls via wifi; or they could sign up for Skype VOIP service to make it their own landline. The application will allows users to ultilize Skype’s service as well as other new features on a PSP.

This is great news for gamers since now they can just carry one essential device on the go and still be able to connect with their family and friends. As a down side with most VOIP, the signal strength will be limited by their connection bandwidth, this might be a drag since you need a wifi hotspot in order to make a phonecall. Hopefully, Sony will partner with various other telecommunication companies to allow users to use their PSP just like a mobile phone. Until then, making a call is as essential as finding a good wifi hotspot.

Reportedly, World of Warcraft gamers are getting performance boost up to 50% simply by having WMP running in the background. Apparently, European forums started reporting last month that running WMP in the background noticeably cuts World of Warcraft load times, specifically in high-traffic sections of the game, though US gamers have just recently caught on.  Some gamers even reported that it improves game latency and framerates, although these improvements are only being experienced by a handful of users at the moment. If you play WoW, why don’t you give a try and see if it works for you. Words are Blizzard is aware of the issue and currently looking into it. For once, gamers are not thrilled if this “glitch” ever get fixed.
