nVidia press conference on the launch of the nForce 615/620
On Friday, yesterday, nVidia invited to the press conference at CeBit and presented the nForce 615D and 620D there. But let's start at the beginning. At first they indulged a little in self-admiration, but then an interesting number came across:
Last year, according to their own statements, 100 million graphics chips were sold.
At nVidia, too, one wants to see the future of the PC mainly as the control center of the networked home. First, some analyzes were presented that were supposed to show the increased importance of the Internet up to 2006. According to this, in Europe 20% of the population would have broadband internet access in four years, in the USA it would be 5 percentage points more. This would be used as follows: 50% of the users would download music, 33% would use streaming video applications, 60% would play online while over three quarters of the users would play CDs.
In the business sector, too, the progressive office connectivity would result in broadband use become more and more important, also for the individual workplace. From all of this one derives, rightly, an increasing demand for the internal bandwidth of the PC and promptly turns it into the convergence center of the digital home of the 21st century. This bandwidth should, how could it be otherwise, best be achieved by a system based on nVidia's motherboard chipset 'nForce'. Now it has an integrated graphics unit based on GeForce2MX, so bandwidth is twice as valuable here.
So it is not surprising that during the presentation of the nForce615-D/620-D only showed the performance gain through 166MHz DDR RAM when using the integrated graphics. When using an external graphics card, the nForce is likely to benefit even less than SiS and VIA already did, since they were already in the old configurationthere was significantly more memory bandwidth than CPU/chipset bandwidth. These scissors would only be unfolded further.
Interestingly, it seems that the 'Southbridge' is now being given significantly more weight MCP (Media Communications Processor) as on the IGP, formerly known as Northbridge. Here one would like to further develop the sound capabilities in particular. Even if they are still little used in home systems, they are already quite extensive. At the press conference, the DVD of 'Star Wars: Episode 1' was shown with Positional Audio via nvDVD, the recently introduced in-house media player from nVidia. 'Serious Sam: The Second Encounter' was also presented with surround sound emulation via DirectSound3D, which the MCP converts to Dolby Digital in real time.
In the long term, audio standards will focus primarily on the Dolby formats and support the 3D sound in games mainly via the DirectSound3D interface.
