Initial Raspberry Pi 4 Performance Benchmarks
In many different benchmarks, the Raspberry Pi 4 was delivering performance similar to the ASUS Tinker Board with its Rockchip Quad-Core RK3288. The Raspberry Pi 4 performance is certainly a dramatic upgrade over the Raspberry Pi 3 on the CPU front.
CPU-based video encoding on these ARM SBCs is certainly still slow. In some of these heavy multi-threaded workloads, the Raspberry Pi 4GB came in slower than the 2GB version, likely due to the default enclosure on the Raspberry Pi 4 Desktop Kit leading to slightly higher operating temperatures than a bare 2GB version with passive heatsinks.
But for most workloads not contingent upon the system memory, the two Raspberry Pi 4 boards tested were offering similar performance -- and being very close to the ASUS Tinker Board.
