It's about time really.  Radeon vii has a whopping 1TB/s bandwidth

Some performance comparison to the old vega. Not too shabby at all. Overall looking to be a great high end card but prices are on the high side, still cheaper than nvidia so there is that.

it has 16GB

Hopefully by the early to mid 2020s we start to see this become the standard, with the flagships going for 24 or 32, that would be great.  The throughput is getting to the point now on bandwidth and latency where supporting such high amounts of VRAM is becoming increasingly more viable.

By then we might be at GDDR8!
I read that one day even RAM will become obsolete because SSD will become so fast they can be used as RAM?  This wouldn't apply to VRAM though?

Problem with that idea is like the idea of invalidating CPUs in favor of GPUs. RAM is very good at specific tasks and each generation keeps improving on the last, same for CPUs, it would make no sense to throw out something that works at this time. Maybe in a few decades we could see NVME style drives with massive amounts of storage being used with RAM, but not replacing it.

It's actually gone the other way, ram being used as storage and non volatile versions of ram like optane. You just can't beat the speed of ram and it's related counterparts.

There is a general rule.  Speed and size are interchangeable but both go up with time.   eg.  L1 cache=  kb in size, TB/s in speed. HDD= few 100 mb/s and TBs in size.

eg.  L1 cache=  kb in size, TB/s in speed. HDD= few 100 mb/s and TBs in size.

Newer CPUs are starting to push up into the MB range for their caches and that makes me drool.  Xeons have been doing it fairly regularly the last few years, if I recall higher end Xeons had 64MBs.

L1 is still in KB, usually 32-64Kb, L2 single MBs, L3 as high as 256MB in AMD Rome CPUs

Thanks, Doc, what gave me the idea is that AMD is employing something similar to that for NVME drives, it's called StorageMI and lets you allot a certain amount of NVME SSD storage space as usable RAM, it was said in the specs that it's somewhat slower than DDR4 RAM - it functions at around the same speed that DDR RAM was at around 17 years ago lol.
The reason I find it intriguing is because there's a lot more storage space available in SSD than there is in RAM or VRAM, and you could easily allot 1 TB of storage for it!

Both you and Vlad are right, this looks like something to use in addition to RAM, not replace it.  I would also worry about wearing out SSD.  By the way, is wearing out of RAM or VRAM also a concern?

Not really and if those go bad it is covered by warranty so long as you didn't cause it to fail. SSDs are also becoming better with longer lives, modern SSDs used by the average person will last a decade or longer with newer SSDs pushing that limit even higher.

Long video but great analysis.  I can't wait to see the final form of ryzen 3000. Going to be a killer product!

Thats why I was trying to figure out whether Sleep (uses the RAM) vs Hibernate (uses the SSD) is better for longevity.  I ended up picking Hibernate since it doesn't use any power at all.

Are you serious?  Is Ryzen 3xxx already out?!

Not out, just announced and early demo. Around April-June it should come out.

Radeon 7 will be fist week of Feb.  I think I might get one if reviews are ok.

I hope it works with my x470F motherboard, I think it should, it just needs a BIOS update?  I cant see a new motherboard adding anything besides native support for the new CPUs anyway.

And will the new GPUs also work on the same mobo? I assume they're PCIE 4.0x?

New boards will have PCIe 4.0 and few minor features. 

Your existing board with bios update should support them just fine.

Thanks Vlad, will the BIOS update also possibly give me PCIe 4.0 lol?  And are the new AMD Radeon GPUs for PCIe 4.0 but will also work fine with PCIe 3.0?

Here are some things I have seen online, it says the new chips may be 16c/32t still support dual channel DDR4 and PCIe4.0

The TDP are pretty high.  I wonder how reliable this info is?

Yep it will work in pci 3.0. not much benefit at this stage. Maybe in the future when cards become a lot faster than they are already.

Bios update I doubt will give the capability, it's mostly hardware level.

Yeah for 16 core the tdp will be higher, no way around that. But 8 core vs the old 8 core the power is almost half.
