PCI-E 4.0 has double bandwidth of PCI-E 3.0

[WYP]

Tom's Hardware this week have managed to get a few details from the upcoming PCI-E 4.0 standard.

According to their data PCI-E 4.0 will have a base speed of 16Gbps per data link, which is double that of the 8Gbps capacity of today's PCI-E 3.0 standard.

At present the standard has not been drafted, so do not expect PCI-E 4.0 in any motherboards or devices anytime soon.

For those who wonder, Why do we need PCI-E to be faster? or How does this Benifit us? Well the answer is simple; size, cost and obviously speed.

Fewer data links for the same data rate will reduce the size of a connection required for the required performance, which is great for mobile and can also reduce the cost of devices by decreasing the required data links.

Speed will also be a great benefit, while most devices will not bottleneck on PCI-E 2.0, never-mind 3.0, more and more devices are being ran through PCI-E (PCI based SSDs and PCI based Raidcards being a prime example) and as such the stresses on our PCI lanes will continue to rise, so a speed boost will eventually be required.

No matter how we look at it PCI-E 4.0 will be a welcome boost, regardless of whether we need it at the minute. Hopefully we will here more regarding the next generation of the PCI-E spec as the spec is developed and finalized.

Guessing this will be X109 maybe or what ever comes after Intels X99.

I think I will save for a long time and just go all in when new stuff come out. Hopefully future proof my system for about 5 years. My plan was to build a new rig around this time next year. Lets see what is available at that time.

We will need this for when we start looking at resolutions beyond 4K.

You should know by now that future proofing for more than three years doesn't exist.

I can dream

But then again who on this forum doesn't upgrade within a year or two anyway.

Meh using a motherboard with version 2.0 is still perfectly fine. It'll be a while before you'll actually need version 3.0, let alone 4.0.

Doesn't mean you can't hang on to a system for that time period.

I still use the system I built back in 2009 that has an AMD Phenom II and a GTX 560. It still handles modern games at reduced settings (medium/high) just fine despite its age.

Yeah, older machines do hold their own quite well nowadays, an tbh a lot of games don't look too bad at medium or low settings.

The only games that ever made my older rigs chug were higher setting on some RTS games.
