PCI Express 3.0 Specs Delayed

PCI-E 3.0 was originally expected for end of this year... now 2011 >_>

I wanted USB 3.0, SATA III, and PCI-E 3.0 on my next motherboard upgrade but I don't think I can wait for 2 years.

I'd rather have them release it late and well working than have it early and full of compatibility problems.

Actually, it was expected next year. The spec would have been finalized this year, but products wouldn't hit the shelves until 2010.

Well that means DX 11 GPUs won't ever be using PCI express 3.0

Are we maxing out PCIe 2.0? I didnt think Vid cards were.

I think the real reasons for the delays of PCI-e 3.0, USB 3.0 and SATA III is result of bad economics. The companies are saving money by maximizing the profits from old standards before the new standards are implemented. It is good idea to let the engineers to prefect the spec during the down time of course.

I agree with haunted one, i'd rather see it delayed and working properly with full backward compatibility then rushed and screwed up.

It'll be ready when it's ready.

yep. I can wait, besides, PCIE 16x and 16x 2.0 don't differ all that much anyways. usually just a couple of frames depending on the game. i'd think the same with 3.0

everybody is waiting for the 3's. USB 3.0, SATA 3, PCIE 3. and Diablo III.

Yeah... it gets annoying...




I don't believe we're maxing out PCIe 1.0.
However, the higher bandwidth is good for crossfire (were you have less lanes meaning less bandwidth, actually hitting a cap).

PCIe 1 is still good enough for most people. I remember when the 8800GT came out boasting PCIe 2.0 but the reviews said it really needn't because it didn't come close to saturating PCIe 1.0.

Now with the likes of Radeon 4870x2 and Geforce GTX 295 PCIe must already come in handy. But we can probably wait another year before PCIe reaches it's limit, if it doesn't last even more than that (probably for the mainstream graphics card market it will last another two or three years).

forgot to add "2.0" at the end of "Geforce GTX 295 PCIe" and before "another year before PCIe". Sorry.

Big deal. I'll wait contently. If nothing else, it'll give me plenty of time to get more "bang from my buck" from the hardware i already have. It's not like we will see a magical increase across the board with the new spec. It'll take time before the improvements are "realized"

Just my two cents.

Any one got any links to the actual papers for PCIe 3 fight now? I'm interested in how much power are available for use.

It's interesting how we want these new 3's. The only new standard, the USB 3 would be used to the full potential here since we have yet even saturated SATA I or PCI Express 1.1 with the current HDDs/GPUs. So the delay shouldn't affect performance at all as you most likely won't gain any performance by going PCIe-3.0 or SATAIII even with the new DX11 cards. I'll gladly wait. PCIe 2.0 and SATAII is working quite well, no bottlenecks to speak of here.

video cards, probably not, but massive, server raid arrays likely could when the next gen of sata/sas appears (as far as i'm aware, pci-e raid cards are typically 8x and not 16x)

SATA I has hit peak (with SSDs)and same with PCI Express 1.1 (with GTX 295), just not 2.0.

While I am in the same boat as you and was looking forward to upgrading on FY-2010, my engineer's background says it is better to wait and hopefully get better hardware than to rush in and get something with design faults.

Agreed. Oddly, this article reminded me of an ancient PC problem with the i820, ASUS, the P3C2000 mainboard, and the MTH design problem that was rushed into production and later recalled by ASUS, who's customer service back then was worse than terrible.

Man, and I was hoping to wait till Q1 2010 to build a new computer for the USB 3 and PCI-E 3.0. I guess I might as will just get it over with by getting a Core i5 system... doh!

"The only new standard, the USB 3 would be used to the full potential here since we have yet even saturated SATA I or PCI Express 1.1 with the current HDDs/GPUs. "

SATA-II is being already saturated by current gen SSDs and a complete bottleneck for next gen SSDs coming out soon. So yes, you don't know what you're talking about.

As for PCI-E 3.0, 2.0 has 20% overhead data and 3.0 has 1.5% overhead data. Less energy will be wasted on overhead on top of overall more bandwidth.

Win7. All those nifty UI affects also take their toll. Vista had a copy of the textures/etc needed in system memory, then copied it up to video memory. This helped reduce latency by not relying on the bottleneck between CPU and Video card. Win7 now stores everything in video memory, so any "updates" it does to your screen requires copying down the needed data to the CPU over your PCI-E, modifying, then re-uploading the changes. This will overall increase PCI-E usage, also your UI thread stalls on waiting for the data to get back from your video card. The faster you get data back from your video memory, the less CPU time wasted on stalling.

you may say PCI-E is already fast enough, but when you compare 4GB/s of PCI-E 2.0 to the 38.5GB/s of tri-channel corei7, you can see why Vista opted to just duplicate/waste the memory in order to reduce latency.

@Benjie: Those "nifty" Win7 effects don't take that much of a toll. Linux eye candy(KDE 4 or Enlightenment e17 + Compiz effects) is far more advanced than Windoze ever has been, and it can run on a fairly crappy spec laptop. Granted, MS didn't do such a great job on making their eye-candy efficient, but all the same, it's not maxing out anybody's GPU, much less their PCI-e bandwidth.

this is a bummer

Unless your the kinda of person that drops $500-$600 USD on a "1" videocard a year then I wouldn't worry about it as if it wouldn't matter to you in any way so of form any how.

My GTX295 in SLI aren't capped yet on my PCI Express 2.0 slot yet even running @ 729/2400Mhz my QX9650 is bound at 4Ghz.

The 2.0 slot has alot to offer still

The actual PCI-E interface is never the bottleneck in current configurations. Heck, we can still game with some AGP cards! As long as there's not any hardware to fully use the actual PCI-E bandwidth, I say there's no need to hurry with PCI Express 3.

I'm more interested in Sata-III and USB3.0, where actual peripherals do suffer from the limited bandwidth.

We don't need this yet, what we need is affordable 300GB or more SSDs.

When the Radeon 5XXX cards come out there will most likely be a problem when it comes to running cards in crossfire. Currently PCIe 2.0 x16 lane has a total bandwidth of 8Gb's so that's 4Gb's on a 8x lane or PCIe 1.0. A Radeon HD4870 has an official data rate of 3.6Gb's which isn't an issue for currant cards but consider the jump form the 3870 to the 4870 pushed that transfer rate from 2.2Gb's you then realise this might be an issue for anyone wanted to do 5XXX crossfire on a P45 or P55 motherboard.

With any luck ATI will be able to get more work done per clock cycle so they won't have to increase the data rate (Nvidia cards are lot more efficient, a GTX275 has the same data rate as a 8800GTX) to much.

Delayed? Bummer...

PCI-e 2.0 chipsets only use x16 lanes and not the 48x lanes the spec allows. Since it is likely that 3.0 cards will work on a 2.0 or 1.1 bus, this is not a big issue like usb 3.0, where the speed and hopefully CPU utilization will be much lower.

SSALIM KNOWS WHAT HE'S TALKING ABOUT! SSD'S FOR THE MASSES! HARD DRIVES ARE THE REAL BOTTLENECK! ahem...
Also Nvidia GT300! Another 3! also Sata 6GB/S as it is officially called is not needed, at least in the high end consumer market SSD's have not reched this barrier yet. But yeah was hoping to build me a Pci-e Gen3 rig for use with sli and such, also great furture proofing. but ohwell, if i have to wait. i must...
