1Is it fast for normal work?

Multitasking slowed the reviewed base model
Albert Unbox reported slowdown while playing YouTube, recording the screen and downloading software together. He also demonstrated lag in Photoshop. His unit had 8GB RAM and 256GB storage, so this is not a measured result for the 16GB/512GB configuration.

Short CPU stress test did not report thermal throttling
Britec09 shows CPU-Z stressing the processor and HWiNFO reporting no thermal throttling on the 8GB/256GB review unit. Test duration, ambient temperature and firmware were not fully documented, so this does not establish sustained behavior for every workload.

Included SSD ran hot during sustained stress
Robtech found the included 1TB eKit Store SSD reached thermal-throttling territory when he stressed the CPU and SSD together for an extended period. This concern applies to his drive and test conditions; it is not a normalized temperature result.

Batocera 43 connected to Wi-Fi and Bluetooth
Team Pandory booted Batocera 43 from USB and reported working Wi-Fi and an 8BitDo Pro 3 Bluetooth controller on his 16GB/512GB unit. This is a basic compatibility check for that configuration.
