A single lane of PCIe 4.0 has a speed of 16GT/s

https://en.wikipedia.org/wiki/PCI_Express

Intel Z790 chipset is connected to the CPU through a DMI 4.0 x8 lanes (128GT/s)

https://www.intel.com/content/dam/www/central-libraries/us/en/images/2023-09/block-diagram-intel-700-series-chipset.png.rendition.intel.web.1920.1080.png

How is it possible to have up to 20x PCIe 4.0 (320GT/s) from the chipset if the chipset only has a bandwidth of (128GT/s) from the CPU?

Before anyone wants to point out that Optane is better for random read / write, do also show me 8 Tb of Optane storage.

Rules

Be civil. Uncivil language, slurs, and insults will result in a ban. If you can’t say something respectfully, don’t say it at all.
No Unoriginal Sources, Referral links or Paywalled Articles.
All posts must be related to Intel or Intel products.
Give competitors’ recommendations only where appropriate. If a user asks for Intel only (i.e. i5-12600k vs i5-13400?) recommendations, do not reply with non-Intel recommendations. Commenting on a build pic saying they should have gone AMD/Nvidia is also inappropriate, don’t be rude. Let people enjoy things.
CPU Cooling problems: Just like 95C is normal for Ryzen, 100C is normal for Intel CPUs in many workloads. If you’re worried about CPU temperatures, please look at reviews for the laptop or CPU cooler you’re using.
