PCIe 4 specification finalised and released

[porina]

Quote

This week, PCI-standards consortium PCI-SIG (Special Interest Group) has ratified and released specifications for PCIe 4.0 Specification Version 1, uploading the documents to their PCI-SIG Specification Library. This marks the full release of PCIe 4.0, following up on June’s revision 0.9 specification publication. Doubling PCIe 3.0’s 8 GT/s (~1 GB/s) of bandwidth per lane, PCIe 4.0 offers a transfer rate of 16 GT/s with flexible lane width configurations, providing significant I/O performance benefits useful for storage, networking, and AI applications. At the same time, PCI-SIG has targeted Q2 2019 for releasing the finalized PCIe 5.0 specification, so PCIe 4.0 won't be quite as long-lived as PCIe 3.0 has been.

If you're feeling the need for more expansion bandwidth, you can look forward to PCIe 4.0 offering double the per-lane bandwidth over 3.0. This has now been finalised so people can start testing real products using it. It may be assumed they would have a head start using earlier versions of the specification, so they don't have to start from scratch now, and work will be mainly to iron out any implementation and compatibility bugs. From our perspective, could AMD and Intel implement it in the next generation chipsets? We'll have to wait and see. Assuming the number of PCIe lanes doesn't grow significantly in the consumer space, the increased bandwidth may help with using more and/or faster storage or IO.

 

It is also interesting that PCIe 5.0 has also got a date, under 2 years away in Q2 2019.

neat, so 4x GPUs coule be a thing now

4 is going to be awfully short lived. I'd be surprised if anyone even bothers adopting it if it's going to be around for likely less than a year of product launches. Hurray I guess? 

[Jurrunio]

Useful for some more insanely fast storage maybe, mostly irrelevant though.

Why didn't they just skip this one?

I would assume that work has been going on in the background for a while now, so the time to implementation shouldn't be too long. Like so many things, not everyone will have a need for it, but for those that do, this will be a big thing. 

 

If comparing dates, we should do it like for like. Assuming the 5.0 date is the anticipated finalised release date, it is almost 2 years gap. That's a long time when it comes to tech.

 

Skipping 4.0 and going straight to 5.0 in its place would be a bigger jump with increased risks of problems.

because its not the 9th version

Next one will be DDR5 memory ffs technology...

Building a pc is sucks for now

not really, plenty of choice so its not bad, also remember when ddr4 was brought out, pretty sure only x99 used it whilst consumer still had ddr3, so even if ddr5 comes out youll still have probably a platform change before consumers get it

Yes it its there's plenty of choices but each year amd and intel will release an incremental update..

For example when Ryzen is released a moments later coffee lake is released for just a quick cash grab answer for amd ryzen before releasing their cannon lake..Or when RX 500 series released a couple months later after RX 400..whats next? owh 1070ti.. yes i know competition right..its so unhealthy

But DDR4 is just been around recently unlike DDR3..

Why the rush?

Because we are not the only one thats gonna use DDR5?

Server for enterprises?

its the same with anything, i couldve waited 3 years for the last iteration of zen and probably get a large performance bump over the 1600 but i wanted to build now, competition is what gets the consumer a better deal at the time, despite a company shooting current owners in the foot like with the 1070ti release 

 

regarding ddr5, thats why i mentioned x99 getting ddr4 first, chances are consumers will be using ddr4 for a long time and prosumers/enterprises will use ddr5 first

It's really interesting how ddr 2 came out 3 years after ddr1, ddr3 4 years after ddr2 and ddr4 came out 7 YEARS after ddr3, what took them so long to develop ddr4?

Yeah but say i want to build now..but then they stab us in the back by releasing something more powerful with similar price a months later because of this competition?

You know they will ALWAYS release something newer and better around the corner. Say you had waited to get the next one, but the one after that is still going to be there. If your goal is to be at the leading edge at all times, you're going to pay for it. Why should they hold back just so you can feel leading edge for longer? Or do the sensible thing. Get what makes sense at the time, then run it until you need to upgrade. Apart from "more cores" CPUs really haven't changed that much in the bigger picture. GPUs arguably make more impact, particularly for gaming performance.

Umm didn't they release 1.0 to their members back in June? They announced they had, and that they already had controllers and parts for it taped out... Is this just the public release of the spec, or did they make another revision since the final member release?

If u look through my specs i am still rocking i5 6600k..

What's the problem then? You don't need the latest. If you do, hand over the cash. That how the market works. Some people run their device for 10 years if possible. Others upgrade every chance they get. Companies need to keep the ball rolling. A yearly cadence is fine although I'd prefer more substantial gains which usually don't happen year to year.

I like how you consider that sort of old, I'm still running a 4930k and my friend is running an i7-960.

I dont have a problem but some might..and cause i am not selfish and i also runs a hardware store thats why i care about it.

Just like my previous comment 

Now do u agree if say companies always give us an incremental update each released? No right but that is exactly whats happened nowadays

Yes, they don't stab you in the back by releasing an incremental update a year later. They'd stab you in the back if they released a disruptive product 5 months later that makes yours obsolete.

 

Considering you're running a store, it's surprising hearing this from you. You should be happy about moving more product even if your margins are thin.

You make it sound like a new thing, but this has always been the case as long as I've been into PCs, which might be longer than some on this forum have lived. And I'd still disagree on sucking, or that it is a problem. I want more, faster, quicker, yesterday!

I'm still running a 6700k in my main system too, although I do have newer systems for test while I decide on what to swap to eventually...

According to Anandtech's writeup, the June release was version 0.9. It was probably "close enough" to work with but not final.

Do i? hmm..

I am not saying that its a new thing its just it reach its climax now..

U disagree oh well...just keep releasing incremental upgrade each year so we can buy em for uhh a little performance boost..Yeah!!

I want any update, big or small. It doesn't mean I'll buy all of them, and I skipped Kaby Lake for example, only recently getting a Coffee Lake to test. If there wasn't any update, we wont get any more. For example, what else might they do? Do releases half as often, which appear twice as big? It doesn't get us any further, and you will miss out more if you upgrade between updates.

 

Just over 2 years ago, I was still on Sandy Bridge before upgrading to Skylake. I think I left that a bit long, as a Haswell test system I got before going Skylake showed me what I've been missing. Similarly I'm testing Skylake-X, Coffee Lake, Ryzen, before deciding what to move on from the Skylake system currently. Probably none of those still... whatever is first of Cannon/Ice Lake might be the one.

Well its easy for u to say...the problem is i run a computer store and i must provide what the market has to offer..

Lets just say my Kaby lake on my display is still full 30 out of 35..while my ryzen  is well 2 cpu left out of 45..

I already ordered more ryzen cpu to re-stock..

My perspective is very much from the consumer side... I can only imagine the problems of obsolescence from a retail perspective, The balance of keeping things in stock to actually sell them (I can't buy what isn't in stock), without risking them going out of fashion and being stuck with something that isn't hot any more. Kaby Lake was in a tough position though... for mainstream it doesn't look so desirable now that Ryzen is here, and Coffee Lake will address that once anyone can actually get them.

 

It's not that Kaby Lake is bad, but the pricing of it is now in a tricky situation. If they were available, who wouldn't get the nearest Coffee Lake instead? Intel can't just drop prices without disrupting the channel. I think what is possible in these cases is some kind of offer to increase value without dropping pricing. Believe there are some game bundles now, but that is a tough one. Better would be mail in rebates maybe. If the effective pricing of Kaby Lake were closer to that of nearest functional equivalent Coffee Lake then I might even consider one to upgrade my systems and retire an i3.

I dont know what become of my kaby lake stocks

I might have to drop the price..better sell em at low price than nothing at all..at least then wont fill any space..

I don't have practical retail experience so I might be way off the mark here. Do you have to buy them outright at your risk, or is there any sale-or-return potential? Also I don't know what kinda margins you get on these, but I can imagine what looks like a minor cut to a consumer might hit profits in a bigger way to the seller.

 

I've debated a career change for a while. Retail (not necessarily in tech) was an option, but the potential risks of starting a business in that area scares the hell out of me.

And u are gonna be like..sh*t should've wait more..

Or u wont cause u know how it works and already get used to it and u just have to live with it. *Thug life

you can wait as long as you want, therell be a point where a cpu cant be much faster so people can wait till then i guess, gpus are another story, im quite content with not waiting as itll probably be dissapointing, like vega

[Doobeedoo]

Neat, more IO throughput and more usage. Will be awesome for many NVMe SSDs indeed.

I kinda feel bad for amd..vega is expensive to manufacture and it seems they dont have the money to go back and start over.

I'm hoping they can now, with Zen architecture finished the big R&D budget is now freed up since improvements on that won't take nearly as much money to do. Also Zen CPUs are selling well which helps a lot too.

 

Picking CPUs to re-architect first was the right thing to do due to much higher sales potential but probably more importantly for their company image, FX CPUs were extremely damaging their reputation and that was hurting everything they did.

And I'm still sitting here with pcie2.0 and ddr3.... fuck I need to upgrade!

Do you even need to upgrade?The interesting thing about today's "progress" is that most people can actually skip ddr4 and pcie 3.

I fully understand where you're coming from in this thread.  I work for a small computer store/system builder that sells parts retail, though on a smaller scale than you.
