The PCI Express 7.0 “revolution” is taking shape, particularly for our graphics cards, although availability will not be before 2027!
While even the most powerful graphics cards like NVIDIA’s GeForce RTX 4090 are only PCI Express 4.0, PCI SIG is shaking things up by evoking – already – PCIe… 7.0!
A rather detailed evocation even if there is obviously no question of finalizing the specifications for a while yet: we are talking about validation during the course of next year.
Validation of PCIe 7.0 version 0.5
PCI GIS – for Peripheral Component Interconnect Special Interest Group – is a consortium formed in 1992 and made up today of the main players in the electronics industry.
Its objective is to organize consultations between these actors in order to define the characteristics of the next versions of PCI computer buses (for Peripheral Component Interconnect), PCI-X and PCI Express. Of course, at Clubic it is the latter which interests us the most knowing that it manages the exchanges between some of the key components of our PCs.
In this case, we are therefore talking about PCI Express 7.0, while PCIe 5.0 is still in its infancy. If the most recent motherboards have integrated it into the management of the PCIe port dedicated to the graphics card as well as M.2 ports for SSDs, real exploitation is still rare.
Bandwidth doubled to 512 GB/s
A rarity which does not prevent the PCI SIG from continuing its work. Last June, version 0.3 of PCIe 7.0 was mentioned with the emphasis “ a doubling of bandwidth between PCIe 6.0 and 7.0 “.
With the announcement of version 0.5 of PCIe 7.0, the PCI SIG is taking the opportunity to clarify its schedule a little: the final validation of the new bus should take place next year – during 2025 – without further details. The specifications currently advanced still mention 128 GT/s per line for a maximum bandwidth of 512 Gb/s.
The use of the PAM4 modulation signal is confirmed and among the consortium’s objectives also include improving energy efficiency, maintaining backward compatibility and improving latency as well as signal reliability. However, don’t be in too much of a hurry: with validation in 2025 and a compliance program scheduled for 2027, we still have time before we see GeForce or Radeon in PCIe 7.0.

Having fallen into video games at a time when it took a great imagination to see here a football match, there a tank fight in these few bars represented on the screen, I have followed all the developments for forty years. Loyal to the PC, but a fan of all genres, I only have trouble with JRPGs. Otherwise, from the driest turn-based strategy to the most spectacular FPS, including sports simulations or musical games, I can do it all... with a preference for management and games combining several styles. My video game pantheon would consist of three series: Elite, Civilization and Max Payne.
