PCIe 4.0 devices are being shown off at IDF 2016

PCIe 4.0 devices are being shown off at IDF 2016, offering double the PCIe bandwidth of PCIe 3.0.



Read more on PCIe 4.0.

Well, it is needed. The new Pascal cards run out of bandwidth from what I read. That is; if you don't run them on PCIe 3.0 x16.

Not true !!!!

Rocking 4 way Pascal Titan Xs here and the bandwidth is fine.

Just another reason for Intel to change sockets.

Really.. This is clearly progress, were getting faster and it is "going" to be needed.

We also need to remember that storage is moving over to PCIe. In a few years NVMe may be the norm, we will need the extra bandwidth.

It also means that PCIe 4 CPUs and motherboards will be much more capable of SLI and CF. Remember that an x8 PCIe 4 lane is a X16 PCIe 3 lane.

In 2025.

If we've not even maxed out PCIE3 yet with four Pascal Titan X then pray tell how PCIE4 is needed?

PCIE3 was released years too early also. It was only done because other than onboard USB3 and SATA 3 Intel's X79 platform offered nothing over X58. In fact, some X58 boards came with both.

My bet is we will see these PCIE4 boards come on new sockets for CPUs that are about 5-10% faster than what we have now, and the PCIE part will be the main selling strategy.

Obviously they're not going to move forward on DDR4 so this will give them the perfect sales pitch.

Even enthusiasts are not on all PCIE storage dude. It's far too expensive for the boosts it gives a regular desktop user. Don't get me wrong, my RAIDR is much faster than a Sandisk (I can feel it, especially loading up things like Photoshop) but that doesn't mean I would switch to all PCIE storage as it costs far too much.

Now in server land? yeah, check out AMD's Zen board with loads of PCIE slots. It's just another server hand me down dude, with the usual "Move along, nothing to see here" sign hanging from it.

Dude, I know that not many people are on PCIe storage. Not even TTL uses PCI storage on his main rig right now. I am just talking about moving forward.

Within the next year everyone will be releasing their 3DNAND to compete with Samsung and we have already seen that NVMe controllers are becoming much more easily available to make consumer drives.

Right now a lot of people buy X99 for the extra PCIe lanes, but with PCIe 4.0 even mainstream CPUs will have tonnes of bandwidth.

At earliest Intel will be adding PCIe 4.0 with Skylake-E and will certainly hit the enterprise market first.

The server market needs the extra bandwidth, so that is why this is being made, same with PCIe 3.0.

PCIe 4.o will be backwards compatible, so it really isn't an issue for consumers. Intel would make new sockets and boards anyway.
