AMD's next-gen Zen 5-based Ryzen 9 9950X benched on AIDA64: up to 45% faster than 7950X

AMD's new flagship Zen 5-based Ryzen 9 9950X processor has been benchmarked again, this time in AIDA64 tests with DDR5-8000 memory... blasting up to 45% more performance over the current Zen 4-based Ryzen 9 7950X processor.

Some alleged benchmarks were provided by AnandTech forum member "igor_kavinski," who reportedly has his hands on an engineering sample (ES) version of the AMD Ryzen 9 9950X processor. He ran the 9950X processor on an AM5 motherboard with DDR5-8000 memory operating at CL34-45-40-42 timings.

Inside, the new Ryzen 9 9950X processor has two Zen 5 CCs and a single IOD, with the CPU packing 16 cores and 32 threads with a base CPU clock of 4.3GHz and boost clock of up to 5.7GHz.

The 9950X rocks 80MB of cache (64MB L3 + 16MB L2 cache) and a 170W TDP. Regarding CPU boost clocks, at 5.7GHz, the Ryzen 9 9950X has the same boost clock as the 7950X, so we get to see just how good the IPC improvements are on Zen 5 versus Zen 4.
