Would you be better off getting a laptop with fast internet 10gb Ethernet and 5g to use AWS?
What does AWS have to do with anything?
I suggest the OP try to find a side-by-side comparison of a top Intel vs. AMD processor for this or a similar use-case. It’ll give better real-world numbers than a generic benchmark that targets more common use cases often related to graphics rendering and the like.
While ROI might be marginal, paying a premium for a server or business/gaming hardware might be worthwhile if maximum performance at any cost is the priority here. While the processor/ram might be identical between two machines, other factors mentioned like heat management, motherboard bus speeds, graphics rendering, and overall reliability/quality could give you an slight edge in real-world performance.
OS is also a consideration. Using a dedicated machine for this purpose with the least amount of extra bloat/software installed will improve real-world performance as well. Maybe even a Windows server OS, and if you’re a real power user than Core (without Desktop Experience UI bloat) install would enhance performance as well.
Why does it need to be a laptop? Can’t you VPN/RDP to an on-premise (or cloud?) server?
