AMD kept the same memory controller as Zen 2. In fact the entire IO die is exactly the same die they produce at Global Foundries in order to meet their WSA with them.Is it correct that the recommended RAM is DDR4 3200? Funny thing, I have 32GB in a machine that is DDR4 3200 and I was thinking about throwing another 32GB. But I may replace the hardware with a 5900x setup. So should I get 3200 or should I get faster RAM? The idea I could use the 64GB until moving it over to a 5900x is available would be nice!
Okay. That will help people with builds and power requirements. Thanks for pointing that out (and @Kenmitch). Most VRMs that can hold up to a 3900x or 3950x should be fine for a 5900x.The Anandtech article had a blurb on that. "All four processors have the same official memory support at DDR4-3200, and the 105 W TDPs will offer a turbo power of 142 W, which is the same as the current generation Ryzen processors."
Huh? Why not buy a 3600 for $180ish? Still a great all around CPU.AMD is now too expensive....never thought I would see that day. I wish I had stockpiled the 2000 series when they were in clearance. It had plenty of horse power.
Yes but the 2700x could be had for $129 and the 2600x could be had for $79. The x470 motherboards were $85....those were some sweet prices.Huh? Why not buy a 3600 for $180ish? Still a great all around CPU.
Those were clearance prices to clear inventory for the next gen. Once those CPUs were sold out, that was it, clearance prices over.Yes but the 2700x could be had for $129 and the 2600x could be had for $79. The x470 motherboards were $85....those were some sweet prices.
Today $129 gets you a 4-core CPU.....2020 is just bad.
People will still have the option to buy the 3000 and lower series, so if you don't like the prices, go previous gen. It's not like game performance was terrible with previous gen processors. Or wait for AMD to introduce their lower cost SKUs, which they should because people preferred the lower TDP SKUs as the power consumption was lower and the performance difference was negligible.AMD is now too expensive....never thought I would see that day.

Zen3 should be about the same as Zen2 in terms of what memory it likes. So I'm just going to be a broken record and recommend Micron e-die again!So... back at it again in a different thread. What's the best memory again ? I'm looking for 32gb of ram under $200 that's at least 3600 speeds.
Base clock is misleading. It's hard to find anything that will run at that clockspeed. You have to have truly awful cooling and run something like Prime95 SmallFFT or one of those awful PrimeGRID workloads to get close to base clocks.I am disappointed that the 5800X didn't release with a base clock of 4 GHz. I've been waiting for an AMD processor that could hit 4 GHz base and wasn't on the Bulldozer architecture.

That's binned for 3600 out-of-the-box. If you want to save a little and don't mind more tweaking (and risking the silicon lottery) then you can get about the same ICs here:
For some reason Amazon has the DDR4-3200 kit for $115, which is a lower price than what you can find for the DDR4-3000 equivalent. Very interesting.

It'll be a 2 x 6 CCX configuration.Will the upcoming 5900x have 12 cores per a CCX (only one CCX), or 6 cores per a CCX (2 CCX's), or will it be 8 cores on one CCX and 4 core on the other CCX (2 CCX's)? I'm debating to myself whether I should go for the 5900x over the 5800x if I mostly use my PC for gaming. Also is memory write bandwidth crippled to half on the 5800x and 5600x like it was with Zen 2 chips below the 3900x or do all Zen 3 chips get full memory write bandwidth this time? So basically the two things I'm wondering about is the cores per a CCX on the 5900x and the memory write bandwidth on the Zen 3 chips below the 5900x.
So a single 8-core CCX is better than a two 6-core CCX's for gaming, for now and most likely 3-4 years into the future?It'll be a 2 x 6 CCX configuration.

We don't know for sure yet because we don't know all the changes that were made for Zen3. For Zen2 it seemed some games did better with 1 CCD (3800x) and other games did better with 2 CCDs (3900x). I would expect the gaming difference between a 5800x and 5900x to be rather small in either direction but we'll have to wait and see from reviews. The longevity question is interesting with the new gen of consoles coming very soon now with way more powerful CPUs than the previous gen. Who knows how much that will translate to needing more CPU on the PC side but my guess is for the next 3-4 years, 8c/16t CPUs should be fine.is a 5900X worth the extra $100 over a 5800X if using it primarily for gaming?...will double the cache and 50% more cores make any real difference?
which games did better with 2 CCD's?...I'm curious if it's a specific type of gameWe don't know for sure yet because we don't know all the changes that were made for Zen3.

I don't know off hand, I just know that some games had the 3900x higher and some had the 3800x (or even 3700x sometimes) higher. You can check Anandtech's bench section or the last little bit of Hardware Unboxed (youtube) reviews, they will show you how the CPUs did across each game tested without having to click through a bunch of pages or watch the full video.which games did better with 2 CCD's?...I'm curious if it's a specific type of game
It's really just there for the suicidal AVX2-heavy applications that drive maximum current.While most applications typically run at above base clock speeds with Precision Boost 2 enabled, you still have to wonder why we even have a base clock speed under 4 GHz any more.
