What do we know about next gen AMD?

[TheNuzziNuzz]

Looking to upgrade my animation rig to threadripper solely for it's PCI-E lanes. I've been shopping around for a cpu/motherboard when I started seeing news about a new release? I also thought it was odd that readripper is only 3000 series while Ryzen is 5800x. What am I missing? Is Epyc a newer option? Or should I wait for next gen threadripper before spending so much $ on an upgrade?

What do you need more PCIe lanes for?  Sounds like as shitload of money for solely that.

 

I'm curious, I have no suggestions or advice.  Feel free to ignore if you want.

Zen 3 Threadrippers are just being late. For past generations Threadrippers are about 4~5 months later than Ryzen 7s of the same architecture, now it's already 9 months.

 

But if you just want PCIe lanes and dont care so much about the CPU's performance, 3960X already gives 64 PCIe 4.0 lanes on top of what the chipset has and I doubt Zen 3 TR will see any increase here.

If you don't need a high performance CPU as well, you could look at old Xeon processors. I think they get up to about 40 lanes. It will only be PCIe gen 3, but basically no GPU can fully saturate the bandwidth, or at least not to where it would be any significant bottleneck.

No, awesome question. 

 

I run 3D graphics, animations, and occasional simulations. Here is my complete current computer/setup: https://pcpartpicker.com/list/9pz8Dc

 

My goal is to be able to have at least 4 3090s. I'd love to do that with a 5950x, but as it it sits currently both cards are running in 8x mode already. There would be a significant performance hit for this, if it would even work switching to 4 GPUs. It would just be a waste of 3090s. BTW, I need 3090s (which are also 3 slot cards) for the extra Vram...and buying the A6000 for a duel slot GPU is just too much money.

I guess, I just don't want to spend a few thousand just to have Zen 3 Threadrippers come out next month. Thank you for the suggestion. I'm looking for 32 lanes of PCI-E 4.0, or 64 3.0

I'm actually experiencing a CPU bottleneck with my 5800X right now. Not to mention, I would need 64 lanes of PCI-E 3.0. Four 3090s would be running at 8x 3.0 which would be a severe bottleneck when multiplied across 4 GPUs. I just wish the 5950x had more lanes!

Oh wow you weren't kidding about needing PCIe lanes. Yeah in that case, as @Jurruniosaid, go with a 3960x. Threadripper 5000 comes out in November at the earlier according to some rumours/leaks and there may not even be an equivalent priced product at launch, so you may be waiting a while to upgrade.

 

Also, with the ~25% price increase of Ryzen 5000 vs Ryzen 3000, I wouldn't be surprised if the price of Zen 3 CPUs are more expensive as well so depending on your budget, you may not even be able to afford it.

Server grade hardware might need more time to be validated to work correctly and stable.

Do I lose any single core performance, or anything else for that matter going to a 3960x from my 5800x? Could I overclock the 3960x (I have a Liquid Freezer 360) to get comparable performance to my 5800x?

Yes, much. Threadripper already has worse core for core perf than the normal desktops CPUs in the same family. It's a trade off for the ridiculous number of cores/threads. Considering Zen 3 already had a 20%+ uplift over Zen 2, you'll be downgrading even more in that respect going to a Zen 2 Threadripper. The overall multicore performance will obviously be higher, but of course, that only matters in workloads where you can fully utilize all the threads. For something like gaming, it will be a huge hit.

Thank you. I'm looking for a a more specific idea of what this will be. I'm not gaming, but my workload is best suited for a 8-16 core CPU. I just want the PCI-E lanes, not the high core count.

One can hope TR5xxx will have close to the single thread perf of Ryzen 5xxx... but yeah that means waiting a while longer. I'm also waiting to see what they come up with.

Yeah, as tempting as it is to jump on this now I think it makes more sense to wait. Especially since based on the previous timeline we are due for new threadripper. I'd imagine it's just slow due to the crazy market right now, but I havn't seen any CPU shortages near me.

 

I guess I just feel like i'f i'm going to drop a lot of money on this #1 I want it to not be a substantial single core downgrade #2 I want to buy it when it comes out so I get the most time for my money.
