What does the future hold, AM6?

I built my rig with the sole purpose of running a few specific programs. It's still doing what it's supposed to do and has the power to accomplish what I ask of it. It is a Ryzen 7 3700X with 64gb of memory, an Nvme and 2 SSDs. The AM4 mobo's BIOS can be flashed to accept a Ryzen 9 5900XT. After that and a new CPU cooler I'm pretty much maxed out in this configuration.

Since I'm not in any particular rush to upgrade I skipped AM5. Since any upgrade I do would probably be considered a vanity upgrade I've decided to wait. Since I've skipped the AM5 series and can probably enjoy my current setup for another 3-4 years. I was wondering what might be coming down the pike that would make waiting that much more enjoyable. Since I don't follow hardware innovations like I use to I was hoping some of you here might have some insight as to what the next generation of computing might be, and when?
 
AM6 will almost be guaranteed to come with DDR6 and PCI-E 6. Beyond that, probably more of the same iterations we've been seeing. Faster single core performance, probably more cores per CCD. Rumor mill has 10 or 12 cores per CCD for Zen 6, making a 2 CCD configuration have up to 24 cores. Whatever that is is likely what we'll see for launch generation on AM6. Expect to see more AI integration as well. Hopefully faster inter-CCD communications for less latency and more consistent performance.

Zen 2 -> Zen 3 was ~30% boost. Zen 3 -> Zen 4 was ~20% boost. Zen 4 -> Zen 5 was a 0-5% boost. Zen 5 -> Zen 6 will likely be a 10-20% boost, and Zen 6 -> Zen 7 (presumably launch generation for AM6) will possibly be in the 5-10% range (pure speculation), depending on initial DDR6 performance over DDR5. Cumulatively, you're looking at a minimum of 70% boost in performance in AM6 compared to your current 3700x. This is only in single core performance, not multicore.
 
If you are OK with waiting, I'd suggest dropping in a 5700X (5800X, 5800XT ... the differences are pretty minor, the 5800 parts run hotter without much performance boost). You should be able to find a 5700X fairly cheap (e.g. newegg shows a couple on sale for $130-ish), and the uplift from a 3700X is noticeable. That will make your life better while you wait.

My primary computer runs a 5800X and I feel no burning need to upgrade it. Like you, I'll probably wait to see if Zen 6 or whatever follows is worth the money.
 
I just want more PCIe lanes than what x870 gave....Not having to worry about connecting 2 NVMe drives and wondering what PCIe slot will down clock to a lower bandwidth to share...

There are a decent amount of boards out there that have 2x pcie 5.0x4 for the m2 slots.

Msi has a helpful page but can def find others out there:

Issue is this

  • PCI_E1 and PCI_E2 share the CPU's PCIe 5.0 x16 lanes.
  • PCI_E3 and M2_4 share the chipset’s PCIe 4.0 x4 lanes.
  • M2_2 and rear USB4 ports share the CPU’s PCIe 5.0 x4 lanes.

I know PCIe 5 offers lots of bandwidth,but to have your PCIe lanes nuttered to x4 or x8 so your NVMe drives can be at x4.. now toss in a dual port 10Gb SFP+ NIC card into a slot..

For me I want my systems to last 3 years or more, so having just enough lanes, maybe, just bugs me.

So as mentioned get a board with x870 that doesn’t have as many shared lanes. Also in your example where are the m2_1 and m2_3 connected to? If they’re both independent pcie 5x4 then the other lanes are totally freed for other usages

Also, I know you’re trying to future proof but in your example you can have twelve 2x10Gbps (that’s bits, not bytes) and still have enough bandwidth leftover for a few other nvme. Unless you’re running your own cloudflare server for the next three years I can’t imagine needing more bandwidth through the mobo.
 
I guess it's just more of a waiting game for me right now. I'm really hoping that we see some sort of generational uplift within the next 5 years, and when that happens I'll make my move. I guess for now I can start to look into all the small bits and parts that will go into a new build i.e. Fans, PSU, M2 Coolers and a new Case. I've been recycling my old case and PSU for so long I'm almost not too sure as to what is out there in those categories. I'm getting up in the years and this next build might just be my last so I'd really like to spend these years with a big smile on my face while I sit in front of my screen.

One thing I think I should add is that there is not going to be any gaming done with this rig, so there's really no tension as to what vid card to install.
 
No point in putting your build parts list together now if your plan is to upgrade in 5 years as all that stuff will change too
