The new chip has undergone processing of the cache memory. The Ryzen 7 5800U includes 16MB of L3 cache, while the Ryzen 7 4800U has 8MB. The cache memory of the second level and beyond is 512 KB for each score, which gives a total of 4 MB. The redesign of the cache is expected to reduce latency and increase inter-core throughput.

The graphics subsystem of the Ryzen 7 5800U processor is based on the modified Vega GPU, which includes 8 execution units and 512 stream cores. The GPU runs at 2000 MHz.
