Z+ SoC 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 Zen cores operating at 3 GHz along with a 24-CU Radeon Vega GPU operating at up to 1.3 GHz.

Cache

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.

Graphics

The Z+ features a Radeon Vega 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 Scorpio Engine (6 TFLOPS) and three times its predecessor.
