how does a bios update give 20% performance boost in these 2 games ?
this needs a double check the guy's videos have about 1-3k views, so you might not wanna take his word on it just yet.

Well Golem.de on launch week stated they saw anywhere from 2-26% increase on FPS on their MSI motehrboard as well.

Compared to the original bios, the new UEFI increases the image rate in our game course between plus 4 and plus 26 percent, on the average even plus 17 percent! In view of this tremendous increase in performance, we had to be certain that our values are correct, and have measured with the Asus boards.This gives us a touch more speed in games than with the updated MSI board.

AMD is continuing the process from before, they want software to use concurrent threads. It's just that Ryzen is a far better CPU than the last gen (not just in terms of single core IPC). The same is with their GPUs -- they excel at anything that can use tons of cores. This seems sensible, as there's a limit to how fast you can push one core.

I'm more interested in Vulkan than DX12, but the next generation is going to make things really interesting.

Lets hope any of these updates will be done in time for the R5 launch in less than two weeks. Would make for a very interesting contrast to launch reviews.

I would assume the majority of mobo makers will have updated BIOS out with the new microcode before the R5 launch at least.
 
Very interesting that a year ago on AdoredTV's master plan video regarding PS4 pro etc having dual GPUs and AMD planning on the PC market going to same way. Now the PS4 Pro is here with the 2 GPU's it is seeming more and more likely that this 'master plan' is starting to come off. Just the developers to go. If the complete story is true, that is very very impressive foresight from AMD and could see them dominate going forward with the AM4 platform and Navi.
 
I was comparing the RX480 and GTX1060 videos that chap with an R5 1400X posted,and you can see the R5 1400X go from massively behind a Core i5 7400 with a GTX1060 to being ahead in the part of the Village of the Remnants which has all those animated NPCs,and is very CPU heavy.

Edit!!

I wonder if it is seen with older Intel CPUs too - maybe an SB one??

It would be cool to see a Ryzen/KL/SB 4C/8T comparison with a GTX1060 and a RX480 in the game.

I've never understood why game devs in particular have such a hard time writing multithreaded code. I'm not a game dev but I write a lot of code and it's trivial to multithread your app and apply OS/CPU-specific branching if you need to.

Need to write your own scheduler? Takes ******' minutes, it's basically just a bunch of binary flags and a simple loop. ( Running in it's own thread of course... ;) )

Added benefit is that it makes bug squashing far easier when everything is modular, instead of trying to stuff everything into one thread and then having to untangle the spaghetti when it chucks an error somewhere. Makes management of a multi-member project far easier too.

Apologies for the vaguely OT rant...

For some games I can somewhat understand it - e.g. Starcraft 2 runs on a model where every client is in lock-step and all actions are fully deterministic which means it's very hard to split work off cleanly as so many decisions are co-dependent (though I'm sure they could have done better than they did...)

However, very few games have constraints like that so most should be way more multi-thread friendly. Games development in general has always seemed to be way behind mainstream development practises in many many ways so perhaps it'll just take time for it to catch up in maturity.

AMD DX12 stonking Nvidia DX12... again.

Its surprising and good at the same time i have high hopes for AMD graphics division and will be supporting them once Vega arrives ...And i suspect Vulkan will be the same too for AMD looking at Doom results a while back ....

Just a question guys..... Are we being blinkered in our thinking now, as I suspect a lot of us are Ryzen owners or interested?

Nope, I won't be buying a new system until 2018/19 as I'm on X99.

I just want information as I love tech and new tech. I find it fascinating that on Ryzen, Radeon not only performs better in DX12, but that a RX 470 is beating the 1060, which is a card that's supposed to compete against the 480 4/8GB

Even more so the issues found with Tomb Raider.

Its been known for a very long time, way before the Release of Ryzen, that AMD GPUs are better than NVidia GPUs for DX12. I think the news is that NVidia still haven't caught up.

Aye, but to the point that a 470 is beating a 1060 when on Ryzen? Let's not forget the 1060 6Gb goes against the 480 8GB; and the 1060 3GB vs 480 4GB on Intel.
