PCI-Express Gen 3 Standard Update

[Mr.Grim]

PCI-SIG, the organization in charge of maintaining and developing PCI-Express, has announced that the third version of the PCIe standard is finished and ready for implementation. The new standard is fully compatible with earlier PCIe cards; a Gen 1 or Gen 2 card will run perfectly in a PCIe 3.0 slot.

Just as PCIe Gen 2 offered double the performance of Gen 1, Gen 3 again offers twice the performance of Gen 2 (8GT/s). Unlike Gen 2, however, Gen 3 incorporates a number of additional changes to improve its efficiency. PCIe 1.1 and 2.0 both use an 8b/10b encoding scheme. This means that 8-bit words are mapped to 10-bit packets. This is part of why PCIe bandwidth numbers are quoted differently. Technically, an x1 PCIe Gen 2 slot is capable of transferring 500MB/s, but 20 percent of this is overhead. The actual data transfer peak is 400MB/s. Instead of using the previous 8b/10b scheme, PCIe Gen 3 switches to 128b/130b encoding. This reduces the amount of overhead bandwidth from 20 percent to less than two percent.

Performance is there... Now what to do with it. Let's brainstorm and try get this up to make more bang ($$) ppl.. *PCI_SIG voice*

I like it nonetheless :-)

is like these guys set out to bruck gamers, is this a part of the new world order?? Y di F*** they are changing pc slot so fats now on us??

this same reason y i dnt build n new box

Well you did notice that they said this doesn't affect current graphics cards right? Read below.

How much this impacts day-to-day computing depends on whether or not vendors make full use of the technology. Manufacturers will be quick to slap PCIe Gen 3 x16 slots on their motherboards, but this, ironically, is where it'll matter least. The additional bandwidth may benefit GPGPU and HPC computing but modern video cards almost certainly don't need the bandwidth, even in SLI.

LOL something newer, better, faster is always on the horizon that why I just choose the best bang for buck parts available and not worry about the coming next best thing unless its something really really major.

PCIE SSD. Something like the OCZ Z drive

Sounds good to me
