WHAT WOULD YOU DO WITH 128 GB/S?
It seems like only yesterday that we were getting our first glimpse at PCIe
4.0 but like the 10nm process, it is now old news. The PCI-SIG have just
released the official specifications and design for PCIe 5.0, which will
offer 32 GT/s raw bit rate and up to 128 GB/s on a x16 interface. As with
previous releases PCIe 5.0 will remain backwards compatible with with older
hardware but it seems that new hardware that will be able to take full
advantage of the increased bandwidth will require design changes.
As with the current release of PCIe 4.0, it will be storage devices which
benefit the most from the new specification, unfortunately your GPU is not
making use of all of the bandwidth available to it on PCIe 3.0 so you
shouldn’t expect any graphical miracles when the new generation becomes
available. There are plenty of reactions and comments from manufacturers
and designers over at Business Wire, but no hints on when we might start to
see PCIe 5.0.
Completing the PCIe 5.0 specification in 18 months is a major achievement,
and it is due to the commitment of our members who worked diligently to
evolve PCIe technology to meet the performance needs of the industry. The
PCIe architecture will continue to stand as the defacto standard for high
performance I/O for the foreseeable future. |
