*** AMD "Zen" thread (inc AM4/APU discussion) ***

Technically if any of this is partially true we can't blame devs. Most gamers had Intel CPU's in their rigs so it made sense to optimise for the vast majority.

I do think tho that there is something artificially holding DX12 back and I think that is Nvidia. They don't have the hardware at the moment so don't want to play AMD at a game where they are not on top.

Nvidia has much much greater Dev relationships so will also obviously want them to do stuff that they think is the right way to go.

100% Nvidia is writing furiously improvements to their DX12 driver. They started with a small update a few weeks ago which they released but my guess is the next gen Nvidia cards will be DX12 from the ground up. I.e Asynch compute enabled and vastly improved DX12 drivers.

I've been feeling it for a while that Nvidia are not DX12 ready. I only have a 970 (horrible Dx12 performance (and Vulkan)) but even the 1000 series I didn't feel like where Dx12 cards either.

True regarding the 1000 series.

We run some benchmarks with Kaapstad 6-7 months ago with TW Warhammer and posted them here.
The Nano was losing 1fps between DX11 and DX12.

My GTX1080 @2190 was losing 20% of it's performance, and the same applied to Kaaps TXP.

However the i3 cannot be overclocked......

Chap is going to test with an RX480 over the next few days,so I think we need to hold off judgement until then.

He also overclocked the RAM on the Ryzen CPU to 2666MHZ and the Intel CPUs to 2133MHZ.

Panos said:
However at very low graphic settings, so VRAM shouldn't be the issue :) but yeah.

Well technically it is meant to be "faster" but either way,I always felt it was one of those benchmark cards like the 8800GT 256MB. Anyway that means one less reason to buy a GTX1060 3GB too!!

Considering the RX480 8GB can be had for GTX1060 3GB money now.....

I tried some more recent drivers and actually did my own benchmark run through part of ROTTR. There was actually a performance improvement in one part under DX12 - but for want of a better word it was hit and miss.

Some set of runs were fine,and others just cratered - I am only running an IB Core i7 so its not really that modern.

Ryzen 5 1400 vs i5 7400 vs G4560 vs i3 6100

Disappointing, performs like an i3.

Look at the CPU usage though.

In BF1 the intels were at 99% usage the ryzen is at 72%

In gta 5 the i5 is 82% the pentium at 85% and the i3 at 85%. Meanwhile ryzen is at 57%.

In assassins creed all 3 intel were at 99% utilisation, the ryzen is at 90% and out performs the i3 by 17 fps

Same goes for witcher 3. Note only the ryzen and i5 were able to push the GPU to 99%.

In tomb raider all intel were again at 99% CPU usage for the most part with ryzen at around 80% - 90%

Now what they should do here is overclock the ryzen, it is unlocked unlike the others and test again with a better GPU to let them stretch their legs when they are not CPU bound.

4 core 4 thread CPU's have had their day and games are using them at max. Hell even with 8 threads the ryzen was close to being maxed out.

If you want to pick a winner from this then that goes to the G4560, for the price that is brilliant.

Its already annoying - I had one of those Sandisk 480GB SSDs which suddenly went kaput last week(it seems to be a syndrome which affects them,as a mate had their one do the same). I only upgraded to Win10 for DX12 which in my experience seems very inconsistent and I should have learnt that lesson after DX10 and Vista(moron). Now I am stuck with 8.1 - I could reinstall Win10 but its locked to your hardware,but at the same time if I were to get a Ryzen 2 CPU next year(or an Intel one) I would need to buy a new copy of Windows 10 just to get proper updates.

Nah it ties itself to your microsoft ID, or atleast it should do, anyhow theres more than one way to recover your key :)

So if upgrade the platform,I can reuse the key - from my skim reading of it,I thought if you made significant changes,ie,change your CPU and motherboard it would not be valid anymore.

Nah, my wife's laptop died so i whipped the SSD out and put it in another, reinstalled Win 10, skipped registration when installing, soon as it booted into Windows it registered itself against her account.
 
I had to request a call back yesterday when swapping out motherboards. After connecting to my machine a failing multiple times to get me re-activated. I then got a call back from a supervisor who generated me a new key. Activated it for me and then copied key into a text file and saved it off for me. Nice retail key to.

Video from random person showing AMD card + Ryzen performing much better than Nvidia in the Division DX12: https://www.reddit.com/r/Amd/comments/62n813/inspired_by_adoredtv_latest_work_the_division/
Click to expand...

The guy made the video after the shocking discovery in the AdoredTV video. This is more evidence that Nvidia's driver is somehow holding Ryzen back significantly. Once more games are tested it may confirm this and basically invalidate every Ryzen review that used a Nvidia gpu (which is all of them).

I hope Nvidia will improve performance on Ryzen, maybe there are other games that have this problem as well.

Also pcgameshardware have found out that the reason the 7700k is so much faster in AOTS is that the developers reduce the number of effects rendered significantly, if you use a quad core or lower. This is in gameplay only and without the user knowing.

This reduction in effects does not occur in the built in benchmark though so any review that used it is valid.
