AMD SLI vs Intel SLI

Reviews

This year has seen the arrival of many new interesting technologies such as PCI Express and DDR2. Yet to this day SLI still remains by far the most hyped about technology. SLI was designed by NVIDIA and allows two select graphics cards to work together. The ability to link two powerful NVIDIA graphics cards together does sound impressive. However I believe that the most important reason that NVIDIA has received so much attention is because they were the first to deliver AMD followers with PCI Express technology.

They did this with the nForce4 chipset series which of course does come in an SLI flavor. SLI (Scalable Link Interface) allows a single system to combine two NVIDIA graphics cards to scale system performance. This technology takes advantage of the increased bandwidth of the PCI Express bus. Currently the ability to operate the GeForce 6600 GT, 6800, 6800 GT and 6800 Ultra in SLI mode is possible. The two cards are linked together using what is known as a bridge chip.

While this technology has the power to almost double the frame rates when operating in SLI mode, you have to remember it will also cost twice as much to use. For example, a GeForce 6800 Ultra SLI setup will cost around $1000 US for the graphics cards alone. This technology is however reasonably good value for GeForce 6600 GT setups, as it will cost no more than $400 US for the graphics cards. The nForce4 chipset series has already become hugely successful for a number of reasons. First and foremost they bring PCI Express support to the AMD64 platform and they do this by offering a flexible upgrade path.

Although SLI enabled motherboards do hold a fair price premium, their unique abilities are worth this price penalty. This is evident through the 750,000+ nForce4 chipsets already sold by NVIDIA. In order to utilize SLI technology there is currently only one chipset that will give a motherboard this support. Known as the NVIDIA "nForce4 SLI", this chipset supports a whole host of new and exciting features. The nForce4 series looks to be the best NVIDIA chipset creation yet. Until recently the nForce4 SLI chipset only included AMD 939-pin support. However, the chipset has been re-released with support for the Intel LGA775 platform.

The chipset still goes by the same model name; now there is simply an AMD and Intel version. The list of supported features is very extensive, covering everything from SLI support to built-in firewalls. Initially some motherboard manufacturers were unhappy with the Intel Edition SLI chipset performance, saying that it was nothing like the AMD version. However, since then Gigabyte, ASUS and MSI just to name a few, have been sampling Intel Edition SLI motherboards. The results have been good, leaving us to wonder who really does offer the best SLI performance, AMD or Intel.

SUSE Linux Enterprise High Availability Extension

Historically, data replication has been available only piecemeal through proprietary vendors. In a quest to remediate history, SUSE and partner LINBIT announced a solution that promises to change the economics of data replication. The two companies' collaborative effort is the headliner in the updated SUSE Linux Enterprise High Availability Extension, which now includes LINBIT's integrated geo-clustering technology. Read more

Open source is mission critical for Europe’s air traffic

It is entirely possible to use open source in a highly regulated environment such as air traffic control, says Dr Gerolf Ziegenhain, Head of Linux Competence & Service Centre (LCSC) in Mainz (Germany). Open source service providers can shield an organisation from the wide variety of development processes in the open source community. Read more

  • DRM display resource leasing (kernel side)
    So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.
  • GUADEC accommodation
    At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.

    A Kickstarter campaign for the Niryo One, an open source 3D printed 6-axis robotic arm, has more than doubled its €20,000 target after just a couple of days. The 3D printed robot is powered by Arduino, Raspberry Pi, and Robot Operating System.
  • Linux Action Show to End Eleven Year Run at LFNW
    Jupiter Broadcasting’s long-running podcast, Linux Action Show, will soon be signing off the air…er, fiber cable, for the last time. The show first streamed on June 10, 2006 and was hosted by “Linux Tycoon” Bryan Lunduke and Jupiter Broadcasting founder Chris Fisher. Lunduke left the show in 2012, replaced by Matt Hartley, who served as co-host for about three years. The show is currently hosted by Fisher and Noah Chelliah, president of Altispeed, an open source technology company located in Grand Forks, North Dakota.
