I'm setting up a new server for hosting our business website and I'm weighing my options between the AMD Ryzen 9950X and the EPYC 70xx processors. I've seen benchmark scores showing the Ryzen 9950X performing really well, even better than many EPYC CPUs. However, I've read that server CPUs are built for longer, sustained workloads as opposed to desktop CPUs, which can throttle under heavy loads. Server CPUs also typically have more memory channels and higher L3 cache, which can really help with SQL performance.
I want to know whether the performance difference between these two processors will be noticeable in real-world applications. Will the EPYC be faster despite having a lower benchmark score, or is this mainly just marketing hype? Will I see a significant difference in day-to-day operations?

I'd go with the EPYC here. They generally offer better long-term performance, especially for web hosting. EPYC systems come with motherboards that provide better remote access and can support high memory capacities and sufficient PCIe lanes, which are essential if you expect high traffic. The Ryzen is great for simpler setups, but it won't manage remote access or heavy workloads as efficiently as the EPYC would.
If this server is for a business, definitely go with business-class hardware. It tends to provide better warranties and services. Also, think about your hosting platform and remember that with high core count EPYC CPUs, any licensing costs might increase based on the number of cores you have.
Just so you know, the new EPYC 4005 series is basically designed to compete with the Ryzen 9000 series and could be an alternative to consider. They're compatible with AM5 sockets and can run on consumer motherboards, but they also come with business-level certifications that the Ryzen CPUs lack. If you're looking for reliability and performance, the EPYC is usually the better bet.
It really depends on what your site needs. If you're just hosting a simple site, either CPU should handle it fine. However, as you scale up, especially with things like database lookups, the EPYC will likely outperform the Ryzen because it’s designed for server tasks. Just make sure you're using your resources wisely; other factors like I/O performance often matter more than the raw CPU power.
There's a common misconception that server CPUs throttle more than desktop CPUs. In reality, desktop CPUs can push their limits harder than server CPUs. Higher L3 cache and memory channels on EPYC do help in certain applications, but the overall architecture of your server and efficient resource usage play a much bigger role in performance than just the CPU alone. If your workload mainly involves web serving and databases, you'll find other bottlenecks before you hit CPU limits.
