PCI Express 3.0 Details Announced

PCI-SIG, the Special Interest Group responsible for PCI Express industry-standard I/O technology, announced the approval of next generation of PCIe architecture, PCIe 3.0

Following a six-month technical analysis of the feasibility of scaling the PCIe interconnect bandwidth, PCI-SIG's analysis found out that 8 gigatransfers per second can be manufactured in mainstream silicon process technology, and can be deployed with existing low-cost materials and infrastructure, while maintaining full compatibility (with negligible impact) to the PCIe protocol stack.

PCIe 2.0 delivers 5GT/s but employed an 8b/10b encoding scheme which took 20 percent overhead on the overall raw bit rate. By removing the requirement for the 8b/10b encoding schem, PCIe 3.0's 8GT/s bit rate -effectively- delivers double PCIe 2.0 bandwidth. The PCIe 3.0 specification will also introduce a number of optimizations for enhanced signaling and data integrity, including transmitter and receiver equalization, PLL improvements, clock data recovery, and channel enhancements for currently supported topologies. The final PCIe 3.0 specifications, including form factor specification updates, may be available by late 2009, and could be seen in products starting in 2010 and beyond.

"Experts in the PCIe Electrical Workgroup analyzed both 10GT/s and 8GT/s as target bit rates for the next generation of PCIe architecture, and after careful consideration of several factors, including power, implementation complexity and silicon area, recommended 8GT/s", said Al Yanes, PCI-SIG chairman. "This allows us to satisfy the next generation performance requirements for all existing PCIe applications while maintaining backward compatibility, and at the same time broadening the adoption of this pervasive technology into new and emerging applications and usage models."

PCI-SIG expects the PCIe 3.0 specifications to undergo rigorous technical vetting and validation before being released to the industry. This process, which was followed in the development of prior generations of the PCIe Base and various form factor specifications, includes the corroboration of the final electrical parameters with data derived from test silicon and other simulations conducted by multiple members of the PCI-SIG.

The transition from PCIe 1 to PCIe 2 is still to take place in Q3 2007 with Intel's X38 chipset. AMD will support PCIe 2.0 starting from its RD700 chipset series. NVIDIA has revealed that the MCP72 will be their first PCIe 2.0 equipped chipset.

PCI Express 3.0 Details Announced

"Get a PS3 and save your $$$ and upgrade headaches and lack of good games."Lol! lack of good games? actually i use my pc for my work so i need to upgrade it regularly being able to play games on it is a bonus =)most games on the next-gen consoles can be ported to the pc except they're all just too lazy to do it and i seem to recall there will be games released for the pc that the next-gen consoles can't handle, so go figure

PCI Express 3.0 Details Announced

I have a ps3 and i have 3 pcs.Its not an upgrade headache,its an upgrade im looking forward to along with a new gpu,probably the G92.Oh and as much as i like my ps3 my current gaming pc totally kicks its ass in EVERY way.I only got it for the exclusives on it like GT5 etc.

Yeah but the hardware is so ahead of the software like quad core and windows vista has a long way to go before this stuff is even normal to have. Like dual core has been out for years and most the software that's still being developed is all still running only for single core cpu's..............

Anonymousat 0:48..i have to disagree.If by dual core i assume you mean in the mainstream, like home user has had dual core? Well no not really i have a so called hyperthreaded pent 4 and my new (6 months old) pc is a core 2 duo E6600.The two couldnt be more different and EVERYTHING runs much faster on the core 2 duo.1 core os and other games? so this doesnt take advantage argument just doesnt cut it.If you owned 1 you would realise the extreme contrast betweeen em.super pi 1m on c2duo @ 3.5ghz 14secondssuper pi 1m on p4 3ghz 47 secondsOh and i can run 4 instances of orthos 100% cpu load AND run a game like far cry with NO difference in gameplay.I couldnt run 1 instance on the p4 without it practically locking the pc up.

It seems to me that even current high end video cards don't need the bandwidth of pci-e 16x. It seems that right now the limitation is still the processing power and not the bus speed bottleneck. AGP8x bandwidth is indeed exceeded by hi end gamed running hd but like the article said, this will probably not be needed until 2010. Just like ddr3 has zero speed difference for now.

Guys its not really that much an issue. Sure there are parts in the PC that are fast.. but if your gaming you have 2 big downfalls... Hard Drives are still slow, and optical media is slower still.Till they fix that there will always be HD bottlenecks and Optical Spin Ups

You can be absolutely certain that we do indeed have the technology to go straight past PCI Express 3.0 and beyond - but of course good business sense dictates that they should release the hardware in stages to drain you for every last penny!

Well optical isn't much of an issue since stuff is installed onto the hdd and in most cases hdd isn't a big problem either, although faster stuff does help load time. Provided that you have enough ram and large vram on video card hdd is not a bottleneck. The video card and cpu multicore efficiency is and they don't even stress the current pci-e so they still have ways to go.
