#INTEL S 775 UPGRADE#
That features list represents an upgrade in almost every category save one: it’s down one ATA/100 port.
#INTEL S 775 SERIAL#
There are four flavors of the new ICH6 chip, and all them share some common features, including four Serial ATA 150 ports, one ATA/100 port, eight USB 2.0 ports, Gigabit Ethernet, support for Intel’s new High Definition Audio, and four lanes of PCI Express expansion capacity. The change is also necessary, because the I/O-oriented south bridge will now be doing lots more input and output. Until now, Intel’s chipsets had been saddled with Intel’s Accelerated Hub interconnect running at 266MB/s, so this change is welcome.
#INTEL S 775 PLUS#
And the 915G is essentially the 915P plus built-in graphics.Īll three of these north bridge chips talk to the other chip in the set, the south bridge-or I/O Controller Hub (ICH) in Intel-speak-via a new, PCI Express-like link, dubbed DMI, that has a data rate of 1GB/s in each direction for a total of 2GB/s. The 915P is Intel’s mainstream chip unlike the 925X, it retains support for DDR memory. The 925X is the high-end chip it will have faster internal timings in its memory controller and support for ECC memory to enhance data integrity for workstations. Their north bridge chips-or memory controller hubs (MCH), as Intel likes to call them-include a PCI Express X16 interface for graphics, replacing AGP, and a new memory controller capable of working with DDR2 memory.Īs in the past, Intel has enabled and disabled features on its MCH chips to create three distinct products. The three 900-series chipsets have a lot in common, as one might expect. If you’re confused by some of the terminology, hang on, because we’ll be explaining much of it on the following pages.Ī block diagram of the 925X Express chipset. I’ll give you a brief overview of this lineup’s new features, and then we’ll look at the new stuff in more depth.

Today, Intel is introducing a lineup of three new 900-series Express chipsets, the 925X, 915P, and 915G. Most of the major features you see on a checklist from Dell or HP are conferred by a system’s chipset, as well. These two chips act as the traffic cop inside a personal computer, allowing all the devices to communicate and function together.
#INTEL S 775 PC#
Read on to learn more about what each of these changes means for you and to see how this first wave of next-generation PC hardware performs.Īt the heart of Intel’s PC overhaul is that too-often overlooked component, the core logic chipset. We’ve tested PCI Express graphics cards from ATI and NVIDIA, and we’ve benchmarked Maxtor’s impressive new MaXLine III Serial ATA hard drives with support for Native Command Queuing. We’ve tested the whole shebang, from the Intel 915 and 925X Express chipsets to new processors including the Pentium 4 model 560 at 3.6GHz. However, this major overhaul of the PC isn’t just about making a better TiVo replacement. For once, I’m somewhat persuaded by the spin, because many of these changes should make computing smoother and easier, better suited to the playback of high-definition audio and video. The marketing spin on all of this says it’s about enhancing the user experience and making the PC a better citizen in the “digital home,” where networked PCs replace VCRs and other such media devices. What I meant to say was that Intel clearly intends to clean up the last vestiges of the circa-1990s PC platform at once, weeding out weaknesses and pulling open bottlenecks. The intent of these wide, sweeping changes is clear: to inflict as much pain on the industry as possible in the shortest time window. Instead, the company has undertaken to freshen up nearly the entire PC platform, with new specifications for everything from memory to storage, graphics, power, enclosures, cooling, processor sockets, and audio. What you may not know is that Intel was not content just to replace the PCI bus. PCI is older than the hills and slower than Jessica Simpson counting her change. This move has been planned for some time now and needed for even longer. Y OU MAY BE aware that Intel is introducing a new PC expansion spec called PCI Express, designed to replace the not-so-gracefully-aging PCI bus and its prodigal son, AGP.
