AMD Radeon RX 6300M performs poorly in leaked Geekbench 5 Vulcan and OpenCL benchmarks
Thanks to BenchLeaks, a pair of Geekbench 5 benchmark results for AMD Radeon RX 6300M mobile GPU have surfaced, seemingly confirming that the RX 6300M is truly bottom of the barrel among RDNA 2 notebook cards. The RX 6300M used in the benchmarks is paired with an Intel Core i7-12700 and is featured inside an HP ZHAN 99 Pro G9 All-in-One desktop PC. Since the RX 6300M is a mobile board, pairing it with a desktop CPU is a strange decision.
Using the Vulcan APIs, the RX 6300M scored 24,371. Per Tom's Hardware, the Turing-based Nvidia GeForce MX450 achieves a higher score of 24,688 in the same benchmark. The RX 6300M scored 30,044 in the Geekbench 5 OpenCL benchmark. Here the GeForce MX450 fell a little behind with an OpenCL Geekbench 5 score of 29,000.
AMD Radeon RX 6300M is based on a severely cut-down Navi 24 GPU. It has 12 CUs for a total of 768 cores, 8 MB of Infinity Cache, and 2 GB of GDDR6 memory. With a boost clock of only 1,512 MHz, the mediocre numbers posted by the RX 6300M are not surprising.
That said, since Geekenbench 5 is a synthetic benchmark, the real-world gaming performance can be higher. So, take the benchmark results with a grain of salt.
