AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

The setup used on demo:

System configurations: AMD engineering sample silicon, Noctua NH-D15S thermal solution, AMD reference motherboard, 16GB (2x8) DDR4-2666 MHz memory, 512GB Samsung 850 PRO SSD, AMD Radeon RX Vega 64 GPU, graphics driver 18.30.19.01 (Adrenalin 18.9.3), Microsoft Windows 10 Pro (1809); Inteli909900K, Noctua NH-D15S thermal solution, Gigabyte Z390 Aorus, 16GB (2x8) DDR4-2666 MHz memory, 512GB Samsung 850 PRO SSD, AMD Radeon RX Vega 64 GPU, graphics driver 18.30.19.01 (Adrenalin 18.9.3), Microsoft Windows 10 Pro (1809).

I'd be amazed if they used 2666 MHz RAM.
 
Does AMD gain more from than the Intel chip?

Also, since that was with 2666 that makes the result it even more impressive.

Can someone with a 9900 run it with 2666?
 
Unknown right now.

One of the big questions about zen 2 is whether or not the IF frequency is still linked to the speed of the RAM.

Depending on the answer to that and how much progress they have made with IF, RAM speed could make a huge or imperceptible difference to performance or anywhere inbetween.
 
We won't know anything until they are release as IO dies may change everything but my gen1 Ryzen responds well to memory tuning, you have guys in this thread posting ~1900 CB15 score with a 2700X @ 4.2 my Gen 1 with some tuning at the same clock speed is only a few points off and we know 2xxx is better than 1xxx.
 
Theoretically the AMD chip would gain more performance from upping the RAM speed compared to the Intel one, but that's assuming infinity fabric works the same with Zen 2 as it does with Zen(+). We don't know that yet.

RAM speed doesn't scale in cinebench like in games. You would see fractional gains with faster RAM.

Running CB with with my RAM at 3200 CL14 XMP settings I get 1797 points, with it running at 3466 CL14 (DRAM Calc settings) I get 1878. That's with things like Steam, Discord etc not running, so just a cold boot. I'm not sure if that's considered a large or small jump in Cinebench scores to be perfectly honest!

Out of curiosity why?

I would imagine it is as one of the disadvantages of SiP's vs monolithic dies is the increase in latency and as crossing a clock boundary introduces latency you'd want to avoid doing that if possible as you're making a bad situation worse.

"Summer 2019" probably means we'll be waiting until Q3, unless the CPUs come out before the motherboards but that seems unlikely IMO.

I'd forgotten that RAM speed doesn't affect Cinebench as much as some other applications. It's not that surprising now.
