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

[Lokken86]

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.

Yup. Ryzen doesn't work as well with Nvidia cards which all the reviewers used because they have the fastest gpu. It would have looked better had they just waited for Vega and tested Ryzen with that tbh.
AdoredTVs review was pretty good. Showed that Ryzen gets far better results using an AMD card due to Nvidias sucky drivers.

Another R5 1400 leak:

Like the previous one they managed to overclock it to around 3.8GHZ it seems.

Yup, anybody want a zotac extreme 1070?

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 ....

I personal think Navi will be when things start to shift to AMD. That prob be the start of small dual GPUs like consoles.

With Infinity Fabric connecting it all. Will be interesting, but might also need a push from Vulkan and DX12 MGPu support to help smooth it out.

I assume it'll be 2018 before the new iteration of zen?

On a 2600 @ stock currently, still struggling to justify a new CPU upgrade

Buy a new GPU and then you'll find it bottlenecks, that's what I did

it depands, Navi will be where AMD's performance per dollar will sky rocket, the scalability would allow them to push for performance crown easily, and much cheaper GPUs than the competition, but this approach must have a downside, we wont know untill first Navi GPU is here and tested.
it could run great or it could be plagued with issues.

AMD own the consoles, the new PS4 Pro has dual GPU based on AMD polaris and some of VEGAs tech in them. Console market is the biggest in the world by miles and devs are now working on the console duals, which then could port to the PC duals, killing 2 birds with one stone. All in the AMD master plan video and its starting to come to light, if completely true.

Fingers cross it all works out and runs like a dream, long way off yet. I am not expecting big things from VEGA, we would have known by now.

Thats not bad at all considering it looks like he was using the smallest bundled Wraith cooler. I'd imagine with a better cooler they might be able to hit 4Ghz

And looks like also 2133 ram....

Looks like another 4Ghz wall or less, AMD let you overclock but is it even worth it.

Wow these AMD chips are hammering intel all over the park and are only going to get better and better, yet all some people are bothered about is that they won't overclock past 4ghz and intel can go over 4ghz even though at 3.8/9ghz they are knocking it of the park, this is starting to remind me of Pentium D vs Athlon all over again.

 

[jigger]

Seems the garden variety chips will do 4.1Ghz, with some hitting 4.2Ghz and a few 4.3Ghz. Overclocking the chip and memory looks to be well worth it.

Current Samsung Zeppelin process used on Ryzen, is designed for optimal range 3.3-3.5, at the minimum power consumption. Anything above needs exponentially more power.
Zen+ would allow higher clocks are is developed using the Zeppelin+, which is more efficient still.

Now regarding your argument, AMD is giving is a lot of CPU grunt power for 1/3 the price of Intel CPUs. So what are you taking about?

Lets not forget the Ryzen 8c/16t CPUs are burning less power for more performance, than the Skylake & Kabylake , even when overclocked (all of them). And significantly a lot less power consumption than the Haswell-E/Broadwel-E lineup.
And I bet you the Skylake-X 6-8-10 ain't going to clock more than 4.2 even if their TDP is 50% higher than the Ryzen 1800X. High IPC and high power consumption it will keep their thermal limits very low.

And we are hitting thermal limits. Yes a quad core at 5Ghz is feasible, but thats how far they go from now on. As more cores are packed, the thermal and electromagnetic interference are getting involved. Except someone develops a twice as big socket.

It is worth it when the base is 3.2Ghz. To get a 4Ghz 4c/8t cpu for less money than a locked i5 4c/4t that will never go above 3.5Ghz

The Intel chips which they are competing against can't be overclocked,and the cheapest overclocking capable AMD motherboards start at £80 which is cheaper than what Intel charges for a Z270.

Don't ignore the X99 platform, which Ryzen is the direct competitor. Everyone who argues for Intel, forgets the X99 platform, on both power consumption, performance and costs in relation to AMD Ryzen.

On what I need the Ryzen CPU (and generaly something with a lot of strong cores), a Skylake/Kabylake are total useless. And the Broadwel-E 6900K too expensive. 3 times more expensive than the 1700, for barely any perf difference between 1700@4Ghz against 6900K @ 4.3Ghz.

 

[jigger]

People keep tripping over on the price difference don't they. We need a flow chart.

Do you care about money?

Yes. Buy AMD
No. Buy AMD + donate the difference to charity.

Yeah,but the R5 1400 is priced a few quid under a Core i5 7400,has a better cooler and the cheapest B350 motherboard is around £80. The Core i5 7400 can't be overclocked and the Z270 motherboards cost more,so realistically its no real point for the Core i5 7400 unless you happen to play a game which is hugely better on a Intel CPU for whatever reason. Looking at the leaks so far it seems pretty close in 9/10 games especially with a RX480.

Quite happy with my OC of 3800 @ 1.2v.
