Something that could be rather exciting for AMD enthusiasts, AMD has officially revealed the AMD Radeon VII at CES 2019. On top of that, 3rd generation Ryzen desktop processors are coming.
Getting ahead of the curve a little here, the Radeon VII is built on 7nm which makes it the first consumer-level GPU to be built with it which is interesting. AMD say it's built on an "enhanced second-generation AMD ‘Vega’ architecture" and it seems it will be a decent boost over the current Radeon RX Vega 64.
When compared directly with the RX Vega 64, AMD said it performed up to 27% higher in Blender, up to 27% higher in DaVinci Resolve and they saw up to 62% higher performance in the OpenCL LuxMark compute benchmark.
Some more specs:
- 60 compute units
- 3840 stream processors running at up to 1.8GHz
- 16GB of HBM2 memory (second-generation High-Bandwidth Memory)
- 1 TB/s memory bandwidth
- 4,096-bit memory interface
When it comes to gaming, that was also mentioned as well of course. It's nice to see Vulkan mentioned along side DirectX too! Naturally, they're only going for big Windows games right now but they did say it offered "35 percent higher performance in Battlefield V, and up to 42 percent higher performance in Strange Brigade 1" over the Vega 64 which is quite impressive.
The Radeon VII will be available February 7, 2019 for around $699 USD.
Additionally, they've teamed up with Google to power Project Stream, Googles new cloud gaming service using their Radeon Pro GPUs.
On top of that, 3rd generation Ryzen desktop processors are coming. They will also be built on 7nm tech, based on the Zen 2 core architecture and AMD say it's the "world's first" to support PCIe 4.0 connectivity. Sounds like it's going to be a beast, as they did a preview of it against an Intel i9 9900k where the Ryzen processor came out on top while also using around 30% less power.
They're launching the AMD Ryzen 3000 series sometime in the middle of 2019.
For notebook/laptop users, they also revealed the 2nd Gen AMD Ryzen Mobile processor with Radeon Vega Graphics coming to a range of devices from companies like Acer, Asus, Dell, HP, Huawei, Lenovo and Samsung throughout 2019.

How is the current state of AMD and linux compatibility?
When I started switching from Windows to linux, I always bought Nvidia GPUs because the AMD drivers were complete rubbish.
Much Much better now if you can get the latest mesa versions and not using some really outdated ones. Still some corner cases with some games which causing system lockups or whatnot, but those things are usually rare. AMD Midrange cards (RX 570,580,590) are really good and Nvidia has nothing to compete them in terms of price and performance, unless you buy used cards.

Excellent generally now if using an up to date software stack.
I've an RX480 / Vega 64 set up (with the Vega VFIO passed to an Ubuntu VM) and they both run games just fine. The driver install is simpler with AMD and the workstation experience is better - I see less crashes switching VT than I did with my last NVidia for example. Performance is still an issue but the guys are making consistent progress :)

Well... you can have a 2 pci-express x16 cards (pci-3.0), with 16 pci-express 4.0 lanes..
I'd say, if there are no PCIe 4.0 GPUs coming, then there is no need to change the motherboard for Zen 2.

Well looks like this depends a bit on the GPU. The CPU internal Vega8 does not work since march 2018 and is not fixed yet..... Well it works in general and performance is very good with newest mesa drivers, BUT: you get several complete system freezes a day. At least this is the case for Ryzen5 2500U using ubuntu.
This is the reason I don't dare to try another AMD GPU at the moment.

Sure this isn't the Ryzen CPU lockup bug you're seeing?

Note I've seen this on Fedora as well, only using Gnome shell. I have not been able to replicate these crashes in another DE on my 2500U machine.
I for one will be upgrading my Vega FE -> Radeon 7 (I'll miss that blue though). I have also seen games exceed 13GB of VRAM on my FE so the 16GB is a necessity for me.

but thats the point
by the time games need more than 8GB, u need a new card anyway because even the 2080TI will be to slow
GTAV uses I think 10GB or so at 4k on max settings, its pretty old. So certainly games use that vram today.
In saying that 8GB would be just fine for AMD if they use their VRAM caching tech whatever it was. Unfortunately they need 4 chips to get the bus speed needed.. HBM2 does not come in 2GB modules, which is quite unfortunate.
GTA5 is a very bad exemple. this is a PS3!!!!! game. far away from 4K and rockstar gives a shit about PC. it often feels like they put no effort in PC games. have you ever played GTA with keyboard and mouse? its a pain in the ass, especially flying
i am pretty sure, if they make it again, with a better engine and better PC optimization it wouldnt need 10GB
so lets stick with modern games please. and from what i read and saw on yt even the 2080 has troubles with 60FPS in 4K and VRAM is not the bottleneck

This is great news but $699 makes it expensive.
Really? You know the price of the comparable RTX 2080 is US$799.00?
I'm sorry, but these GPU prices are still absurd. For reference, the past releases in USD:
The 760 was $250 when it released and beat the 680
The 960 was $200 when it released and beat the 780
The 1060 was $250 when it released and beat the 980
But now the 2060 is $350 and won't beat the 1080, so we're taking steps backwards in price and performance.
I was hoping AMD would knock it out of the park. They are competing on the 2080 level, but in order to bring these Nvidia-driven monopolistic prices back down so that the Nvidia xx60 lineup is actually budget/mainstream again this won't cut it.

You should avoid first generation Ryzens, including mobile ones. They have unfixable hardware issues (with some workarounds only). That's a known problem. Second generation mobile APUs are coming this year.

Navi might offer something cheaper but still high end.

Here's to more hoping. The latest leak according to AdoredTV is that the Navi dev team wanted to "let it bake" a bit longer and had to scrap plans to announce it at CES. Radeon VII isn't even a gaming card. It's a "defective" MI50 card that couldn't be used in the datacenter, so they placed display out on it and steered it towards content creator/game hybrids just like with the Vega FE.

Well, and when you get down to that size I'd be willing to bet you're restricted in how narrow you can make some things because at a certain point, making things any narrower would increase resistance too much.7 nm but only GTX 2080 performance? Why? For the same price?
Nice only because we got a open well performing driver on Linux for AMD. Still I'm not much impressed.
Half of the structure (14nm -> 7nm) cannot bring you double of the performance, because the are negative physical effects working against you (read a physics book for details).
Integration density ideally scales quadratically with the inverse of the structure size.
Hence, half the structure size should roughly result in a 4 times higher integration density.
Yet there are many contribution of losses that do not allow performance to scale linearly with the integration density.
Please correct me if I'm wrong. :)
I have been told after the 22nm process the advertised number should not be taken too literally. Circuits are not engraved like labyrinths with tidy vertical walls. There are made of several layers of material. Each one having a different width. So a 7nm process does not necessarily have the double of the density of a 14nm process.
I do not know much more. :)

After read on Twitter about Radeon VII last 1-2 days, I can say people who disappointed with Radeon VII, especially the price are Nvidia fans who were wish cheaper AMD = Nvidia dropping price. Their 'excuse' are no RTX = 1080Ti, better buy 1080Ti.
Personally, I waiting the AMD announcement on low/mid-range GPU. All NVidia cards are out of my reach. Even 1030 is still expensive nowadays, after crypto-currency craziness crashed.

When building a PC, stability and sanity are more important. Constant crashing and hangs isn't something you want to save for. So avoid first generation Ryzens completely.

When building a PC, performance per dollar is a very important value.First generation Ryzens are cheaper and easy to make stable, you should use Bios settings anyway.
MB firmware update and set (may be named differently on your board): 'Advanced->CBS->Power Supply Idle Control' set it to 'Typical current idle'
I did all this , use the newest kernel, the latest mesa driver and so on, disabled C6 and so oń. I am quite sure that its not related to the power management of the CPU, those bugs were solved/worked around in 2018. Those freeze problem which still exist are more likely a GPU problem.

First generation Ryzens processors are stable with correct Bios settings. Most motherboard vendors have updated AGESA.
It was for me and I replaced it anyway, since it eats more power with those "fixes". But for some even latest AGESA and UEFI didn't help. So my general advise is to avoid broken hardware. Second generation Ryzens already don't have that problem.
