[TPU] PCI-SIG Announces PCIe 6.0 Specification

Quote:
PCI-SIG today announced that PCI Express (PCIe ) 6.0 technology will double the data rate to 64 GT/s while maintaining backwards compatibility with previous generations and delivering power efficiency and cost-effective performance. The PCIe 6.0 specification is actively targeted for release in 2021.

PCIe 6.0 Specification Features

  • Delivers 64 GT/s raw bit rate and up to 256 GB/s via x16 configuration
  • Utilizes PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and leverages existing 56G PAM-4 in the industry
  • Includes low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency
  • Maintains backwards compatibility with all previous generations of PCIe technology

If you look outside of x86 you could of been using PCI-e 4.0 since early 2018.

And with how much PCIE4 costs to implement, how much will this end up costing? They really should just break backwards compatibility at some point and move to optical connections to the slot and expansion cards for the sake of cost and ease of implementation.

Backwards compatibility does get taken too far some times. Do we really need to keep putting PS\2 ports on consumer motherboards? Sometimes you just have to shove those who don't want to move forward.

I'd prefer if we keep PS2 ports and kill off all USB A ports and replace them with C so adoption would take off.

Are there any devices that can even use PCIe 4.0 yet?

A bunch of gen4 SSD's have been announced already, will probably go on sale at the same time the X570 motherboards do.

Speeds up to 5000MB/s out of a tiny M.2 drive is pretty insane.

Don't forget the Radeon 5700 and the XT will also have PCIe 4.0.
