'''FireFlight''' is a semi-custom [[quad-core]] [[x86]] [[SoC]] designed by [[AMD]] for Zhongshan Subor for their gaming PC/consoles and introduced in mid-2018. The Z+ features four {{amd|Zen|l=arch}} cores operating at 3 GHz along with a 24-CU {{amd|vega|Radeon Vega|l=arch}} GPU operating at up to 1.3 GHz.

== Graphics ==
The Z+ features a {{amd|vega|Radeon Vega|l=arch}} GPU with 24 compute units. The Compute Units operate at 1,300 MHz, each with 64 32-bit [[floating point]] [[multiply-accumulate]] units. At 1.3 GHz with 128 FLOP/cycle this chip can deliver 3.994 [[TFLOPS]] raw peak performance - about 66% the performance of the {{microsoft|Scorpio Engine}} (6 TFLOPS) and three times its predecessor.
