It looks like you're unsure about your requirements, which makes it tough to suggest anything useful. X3D chips aren't ideal for high-performance work that makes use of extra cache because of their slower clocks. Unless you're working with CFD or gaming a lot, you'll likely be getting less value overall. I also spend a lot on data and machine learning—mostly CNNs and LLMs. The 7000 series didn’t fit my needs, but the 9000 series really helped me consider upgrading to AM5 for better performance in my daily tasks. You should think about whether what you plan to run will gain from Zen 5’s improvements.
The requirements are clear, though new projects are constantly emerging which creates some uncertainty. For instance, my music composition class is nearing completion and I’m just beginning a fresh production. Of course, I wouldn’t have an exact estimate of the computing power needed right now, but at least financially it isn’t a big issue—though that would change if budget was a priority. I currently use a laptop with a 500 GPU for my work. I still have questions about whether we typically train ML models on GPUs. I’m unsure if the 9000 series will be effective. In financial data engineering, the benefits seem clear, but for ML training settings I’m not confident. Perhaps in preprocessing or multiagent RL, but most benchmarks use CPU for things like Resnet and claim significant gains. That said, performance improvements might be limited. Since you mentioned budget isn’t a concern and you noted x3d can slow things down, I’d recommend 7950x or 9950x. I’m not fully convinced about 9950x yet, but it could still be a strong option for me.
Then why not jump straight into a 9950x with 192GB of RAM? In your previous post you did make it sound like budget was an issue. Yes, but how will you get your data for training ready to be fed to your GPU? There's lots of data processing going on in a regular pipeline. In my case? I'm 100% certain lol It's 30~50% better than a 7950x for what I do. I'm just waiting on 64GB UDIMMs to become available to pull the trigger on the new platform. It'll be a 2x CPU perf uplift along with another 2x in RAM capacity for me, win win haha
Money isn't the main issue, but I wasn't sure 9950x could make such a big impact. I was looking for some solid estimates of the performance boost. I have various projects with different pipelines, and some will run on our GPU servers—though that's still under discussion. I just needed general guidance on the gains. It looks like 9950x would be a strong option since the price difference isn't huge here. I'll take that into account.
Using 3D cache on both CCDs would actually create more problems rather than solving them, especially in gaming. It could lead to inter-CCD latency issues instead of helping performance. Having a 3D cache on just one CCD is better, and doing it on both is unnecessary and potentially harmful.
