Hey Lemmy, I need some recommendations for a CPU-intensive slightly mobile rig. I run a lot of engineering simulations and I need a computer that I can move between my home and work on a semi-frequent basis. I'm looking for something more powerful than a laptop and I'll have monitors/peripherals at both locations. Maybe a mini-ITX in an HTPC style case? The sims don't really make use of GPU, so integrated graphics is just fine. They multi-thread a bit, but there are still single-core bottlenecks in the process, so highest single-core performance is probably pretty important. It's also got to handle 128GB of DDR5 and a M.2 PCIe NVMe SSD.
A lot of the faster CPUs seem to need some serious cooling (100W+ TDP!) and I'd rather not have a jet engine roaring constantly since this thing will be sitting right on the desk next to me eating 100% CPU most of the time. Are there small form factor cases that can support water cooling? When Intel says a CPU has a processor base power of 125W, but a Max Turbo Power of 253W, does that imply that the 253W can't be sustained even with enough cooling?
For a case? I've had a fantastic time with my Hyte Revolt 3 It's ITX, fits 240 AIOs and water cooling easily and even custom loops if you're careful about part choice.
It comes with a sturdy carrying handle, is easy to build in, and has been rugged enough to through into a (hard shell) carry-on bag and take with me on work trips.
For CPU choice, why Intel over AMD? The AMD chips usually have lower TDPs. In your case, because you're looking for max single core instead of max multi core, you can look at second tier chips like Ryzen 7800 or Intel 14700 which usually pair 95% of the core speed with 70% of the heat and 70% of the cores. Undervolting is also an option, and AMD makes that easier.
As far as CPU wattage and heat, there's always some kind of tradeoff. It'll be audible but with the right cooler and CPU you can keep it manageable
