AMD announced its first Zen 3 (Ryzen 5000 series) desktop CPUs on October 8.
Compared to Zen 2 (Ryzen 3000 series) CPUs, the Zen 3 microarchitecture has higher boost clocks and around 19% higher instructions per clock. A unified core complex die (CCD) allows 8 cores to access up to 32 MB of L3 cache, instead of two groups of 4 cores accessing 16 MB each, leading to lower latency and more cache available for any particular core. TDPs are the same as the previous generation, leading to a 24% increase in performance per Watt.
AMD estimates a 26% average increase in gaming performance at 1080p resolution, with the Zen 3 CPUs beating or tying Intel's best CPUs in most games.
Ryzen 9 5950X, 16 cores, 32 threads, boosts up to 4.9 GHz, 105W TDP, $800.
Ryzen 9 5900X, 12 cores, 24 threads, boosts up to 4.8 GHz, 105W TDP, $550.
Ryzen 7 5800X, 8 cores, 16 threads, boosts up to 4.7 GHz, 105W TDP, $450.
Ryzen 5 5600X, 6 cores, 12 threads, boosts up to 4.6 GHz, 65W TDP, $300.
You may have noticed that these prices are exactly $50 more than the launch prices for the Ryzen 3000 equivalents released in 2019. The 5600X is the only model that will ship with a bundled cooler.
The CPUs will all be available starting on November 5. AMD will stream an announcement for its RX 6000 series of high-end GPUs on October 28.

I build an AM4 system with the 3600 about 8 months ago. I've been happy with it, but I've expanded my hobby of recording my Friday gaming sessions and would like something with more cores.
With that context explained, I'm curious what will happen to the prices of the 3xxx chips already on the market. AMD has been pretty good with reducing Ryzen prices as new generations arrive, and I wouldn't be surprised if we see the new Ryzen 5 5600X competing with the existing Ryzen 9 3900X. I'm really excited for the efficiency gains of the new chips, but I'm wondering how twice the number of older cores will compete.
Everything is speculation until reviews arrive in November. And for my personal use case the CPU probably isn't what I should upgrade first: I'm still waiting for AMD and Intel to release their new GPUs before I make a decision there. Exciting year for PC hardware across the board.

That's the gold price and the iron price. I wouldn't expect huge price drops on Ryzen 3000 chips right now since the launch prices of Ryzen 5000 are higher, creating a gap in the first place. Ryzen 5000 prices will probably drop by March, when Intel's Rocket Lake is released. Until then, AMD has free reign.
The efficiency gain seems to be a direct result of the performance gain (IPC and clock gain) at nearly the same power usage. Process node benefits (it's assumed to be TSMC N7+) were put into raising the clock speeds. Though undervolting/underclocking your CPU could show great efficiency benefits.
For you, if your motherboard is compatible, you could consider getting a Zen 3 with higher core count in 2022+ after Zen 4 is out. 8 cores for better gaming performance at that time (games will start using at least 8 cores because of the consoles), or 12+ cores if it matters.
AMD is definitely aiming for RTX 3080 performance with its top Big Navi GPU. It could land just short of that, or into RTX 3090 territory (since the gap between 3080 and 3090 is not much).

> I build an AM4 system with the 3600
I think I may have one of those, or a 3400G or something. It used to be easy with Pentiums (I, II, III, IV) and Athlons, now I'm never quite sure which part is which and that makes discussing them on a site like this difficult. At a certain point reading the parts lists, my eyes glaze over, I mentally detach and begin staring into the middle distance.
Perhaps it's me but wouldn't it be better all round if CPUs were named like $marketing_name-$process-$cores-$speed-($graphics_core)?

AMD might be doing that by skipping the 4000 series naming, but we'd have to observe several more launches to know for sure.

Like you, I've got a 3600 running in my latest machine. I'm going to be waiting for a price drop on the new CPUs, before I upgrade. I can also tell you now, you're likely to get more noticeable performance increases by switching from HDD *retarded slow speed* to SSD *400MB/s* or SSD to NVMe SSD *1600 to 3200MB/s*, than any upgrade you do.
I've been playing Space Engineers lately and it's a pretty demanding game. CPU usage goes back up and down not really hitting a lot more than 25%, while my RX480 has hit around 50-60% usage. Admittedly, I'm running at 1360x768 resolution on an old 32inch lcd monitor. With higher resolution it may increase CPU usage a bit. I would expect it to hit the GPU a lot more, though.
I haven't run Mount and Blade II: Bannerlords for a while, because 40GB+ update . . ., but that would likely be a much better game to test.
Really, just get something like https://www.nzxt.com/camapp [nzxt.com] and you'll see the usage while you play and record. Then, you'll be able to make a bit more of an informed decision on, "Do I actually need anything better than what I've got?". I thought that 32GB RAM may have been a bit of overkill, but looking at the usage in a game like Space Engineers, 16GB is almost too little. 32GB looks a lot better when you factor in running a music player, a browser, a chat program, and / or a streaming/recording program, while playing games.

yeah, when i upgraded from my bulldozer guts recently, i went with a ryzen 5 2600 for $125, but got an nvme ssd at 3000 MB p/s. the cp+ram is 2-3 times faster(IIRC) and the ssd is 6 times faster. bought the asrock hdv MB for like $50. very cheap guts and plenty powerful. maybe in 5 years i'll move up to zen4 or something. all i do is code and surf for the most part and the compile times are fast enough for me at this point. if i start writing huge compiled lang applications maybe i'll care more then.

Zen 4 could have a big (1 GB or larger) L4 cache stacked on the I/O die. That could contribute to the general IPC gains, or just benefit certain applications. There's also rumors [wccftech.com] of a graphics chiplet, so you might not need a discrete GPU anymore. Higher core counts are likely, e.g. 24 cores for a 5950X replacement. A TSMC "5nm" node should allow for smaller 8-core chiplets or 12 cores per chiplet.
If all of the above is correct, Zen 4 would be a great option for someone who wants absurdly high compute performance, but doesn't care about gaming (although an RDNA 3 chiplet might be sufficient for gaming too).

I've got a Ryzen 3600 but I put 32GB of RAM in it. It's enough RAM that I can have a 16GB temp fs all in RAM and run things off that, so I can completely bypass hard disks. That way you can easily saturate the CPU.

i've done some of this before, but didn't find a robust solution to things at the time. what are you using to sync between ssd and tempfs for persistance?

There are a couple solutions you can use. One is to increase the time data spend in the buffer before flushing. Another is to use a union file system. Another is to use a synchronizer like asd or unison or even a properly configured rsync. The most robust solution is a combination of the three.
