PCI-SIG, the responsible organization of the same name, has published the PCIE 7.0 Final Specificationsthe main bus with which modern computers work today. In addition, the industrial organization claims to have begun to develop PCIE 8.0 “To continue supporting the investments and route sheets of industry products in the PCIE technological ecosystem”.
More than one can surprise the release of this version so advanced when your computer is probably using PCIE 4.0, the most widespread. But the technological development of this type of standards never rests and is always advanced, especially with as important norms as PCI Express that has left legacy behind Isa, AGP, the original PCI or an increasingly used SATA.
And is that This local entrance/output bus is used for everything on a PCthe internal connections of the integrated circuits of the motherboards (chipsets), communication with the CPU and also to install as important components such as graphics cards, solid state units or dedicated solutions for networks or sound.
In addition, PCIe 5.0 is already being deployed at a good pace and we believe that many suppliers will skip PCIe 6.0 and will directly pass to this PCIE 7.0 that concerns us today. As with the new standards, the beginning of the implementation of the standard will be aimed at Data -based professional applications As artificial intelligence, automatic learning, the new 800 GBE Ethernet, the cloud and quantum computing. And then you will reach the customer computer market, starting with enthusiastic degree PCs and professional work stations.
PCIE 7.0, first optical solution of the standard
“PCIE technology has been the preferred I/O interconnection for its high bandwidth and low latency for more than two decades, and we are pleasedhe affirmed to Yanes, president and director of PCI-SIG.
And it is that the increase in performance is usually the preferential objective for the new versions of the standards. And in this case there is a concrete novelty that we met from its announcement and that will facilitate the improvement of speed: PCIE 7.0 is the First version of the standard that works on optical connections And that is why the industrial group says that it is the most advanced version since its creation.
If we talk about concrete results, the most news is the bandwidth in a lane (x1) of 128 GT/swhich doubles what was offered by the V6 and means that an X16 slot of a motherboard, such as the one used by the dedicated graphics cards, the bidirectional theoretical performance can be raised to stratospheric 512 GB/S.. Another spectacular performance example will arrive for SSDs, with potential data transfer speeds of up to 60 Gbytes per second.
In addition to the increase in yield, the new standard offers other improvements in the reduction of latency, higher capacity or improvement of I / O virtualization to undertake the increase in industry needs. The coding scheme also comes improved Pam4 which is widely used in higher performance networks such as business infiniband. This scheme was released in version 6.0 to increase transfer rates and is the real responsible for the specification reaches such a high bandwidth.
Finally, another novelty of PCIE 7.0 will arrive from the Reduction of the physical size of the buswhat should allow the production of smaller cards and not the monstrous sizes that we can find – for example – in the dedicated high -end graphics.
