Initial AMD Ryzen 7 4700U Linux Performance Is Very Good
The Ryzen 7 4700U could work out quite well for a developer laptop if you are frequently building packages from source... The Ryzen 7 4700U was standing up against the Core i7 9750H even with the few extra cores/threads.
The Ryzen 7 4700U was right beyond the Xeon HP ZBook with the POV-Ray ray-tracer.
With the Tungsten renderer, the Ryzen 7 4700U was also right behind that higher-end Xeon E-2286M CPU.
