It's always great when someone of the peanut gallery stands up with a big target on their back and starts talking about some technology being a "game changer" then switches gears to "do your own research!!!". If you cant back up your point then all you are doing is shitting up the thread with CXL shilling.
The CXL protocol *MAY* be a game changer with HSA implementations, but not only does that not immediately mean it will matter to consumers, but since the majority of hardware out there is still 3.0 with plenty of 4.0 out there, it will be a LONG time before CXL has the market penetration for any software devs to actually care, then it will take them years to actually take advantage of it By then PCIe 6.0 will be out. We still see only a small difference between PCIe 2.0, 3.0, and 4.0 unless you bring in multi GPU or cards like AMD's 5500xt that are gimped with x8 connections.
Censorship has been the death of many a tech site. WCCFtech's whitelist has cut traffic to a fraction of what it once was.
So Techspot shouldnt report on news if it looks bad for AMD? Funny, most people woul
It is as finalized 2 years ago PCIe 4 took to long to certify, look it up, look do you guys want multi gpu rigs back without the horrible issues SLI and crossfire endured, CXL and PCIe 5 will be able to fix everything. So yes the doubling is actually needed even if a single GPU doesn't bang off the rev limiter of the total bandwidth marker.Even if rumours are true, that's not problem for AMD. About only useful usage scenario I could think for those 16 PCIe 5.0 lanes is:
- Put PCIe 5.0 x16 video card (none available yet) on x16 slot running at x8 speed
- Put PCIe 4.0/8.0 SSD (that's PCIe, not M.2) into another x8 slot
That kind of scenario is very niche. Video cards won't need PCIe 5.0 for long time.
Another problem with PCIe 5.0 support is that motherboards supporting it are much more expensive to make than PCIe 4.0 motherboards. I expect we will see Intel motherboards with "only" PCIe 4.0 support even there are Alder Lake processor used. Just because PCIe 5.0 adds cost, cheap motherboards are quite impossible. That's why Intel limited 5.0 for just two slots but it also means that's useless for 99.9% of users.
Also, we don't really need PCIe 5.0 for anything. It's just too far ahead of needs. While 3.0 was outdated, 4.0 is not. To illustrate:
1.0: (Came out) 2003
2.0: 2007 (4 years after previous one)
3.0: 2010 (3 years)
4.0: 2017 (7 years)
5.0: 2019 (2 years)
It took 7 years to double bandwidth from 3.0 and now we are supposed to need another double bandwidth just after two years 🤔
