Intel itself has predicted that installing the microcode updates that are now provided as a precaution against the “falling” vulnerability could be accompanied by a performance loss of up to 50 percent, especially when the AVX2 and AVX-512 instruction set extensions are used. Site standards Voronex Evidence of a decrease in performance in the range of 11 to 39 percent due to preventive measures.
From minimal to significant drop in performance
After the vulnerability (“CVE-2022-40982”) became known, Intel predicted that the performance losses due to the preventive measures taken would be “minimal” to “significant” depending on the scenario, application domain, and application, primarily when using AVX2 command set extensions. And the AVX-512 can be “up to 50 percent”. This puts the expected performance losses in the weak zone that threatens Zen CPUs.
Like the “inception” with AMD CPUs based on Zen 1 through Zen 4 architectures, “failures” in Intel CPUs can also cost a lot in performance under certain circumstances. Intel has summarized all affected models in an overview.
Detailed information such as CPUID and MCU update corresponding to the affected processor are also mentioned. in his official document.Collect performance analysis sampling dataIntel also provides corresponding projections of performance loss and additional effects of preventive measures.
note: Processors from the Skylake microarchitecture and even including Rocket Lake are affected, that is, from the sixth to the eleventh generation.
Benchmarks show performance losses of up to 39 percent
As with the “Inception” vulnerability affecting Zen CPUs, Phoronix also investigated the effect of existing “fall” protection on Xeon and Core processors. Ice Lake, Cascade Lake, and Tiger Lake were used.
AI workloads run slower
As the benchmarks show, AI applications and their corresponding workloads in particular suffer from migration of crash updates. In OpenVKL 1.3.1, OSPRay 2.12, Neural Magic Deep-Sparse 1.5, as well as Tencent NCNN and QMPACK applications, performance losses of 11 to 39 percent can be determined. Tiger Lake brings up the rear in the benchmarks.

The effects of preventive measures against “splashing” and “falling” on game performance remain to be evaluated in the future. However, it can be assumed that a smaller drop in performance is to be expected.
