AMD’s Ryzen 7 4700G (Renoir Desktop) is Slower than the Ryzen 5 3600 in Gaming w/ dGPUs

We’ve written a ton of positive things about AMD’s new Ryzen 4000 desktop APUs. The Ryzen 7 4700G is supposed to be faster or at least on par with the 3700X and the Core i7-10700K in multi-threaded workloads such as content creation and general productivity benchmarks. On top of that, the prices are also the same as the Matisse lineup (recommended pricing from AMD). However, it seems like these APUs fall short of their Ryzen 3000 brethren in gaming workloads, when paired with a powerful discrete graphics card:

As you can see, even the flagship Renoir APU, the Ryzen 7 4700G (4750G) is slower than all the mainstream Ryzen 3000 CPUs including the $159 Ryzen 5 5 3600 in pretty every game tested. Of course, the deltas are marginal in most cases, but gamers who recently bought a Matisse part can have a sigh of relief knowing that they weren’t snubbed.

As for the reason for this deficit, it’s almost certain that the lower L3 cache size on the Renoir processors is to blame. AMD includes a massive L3 cache on the Ryzen 3000 desktop CPU to make up for the latency penalty imposed by the chiplet design. It’s often marketed as GameCache as it vastly improves gaming performance:
