TL;DR · WeSearch summary

SPEC has released an updated CPU benchmark suite, SPEC CPU2026, which includes 52 workloads, an increase from the previous version. The new suite aims to modernize benchmarking while maintaining portability. Initial tests show that current desktop CPUs outperform the reference system used for scoring, the Ampere eMAG 8180.

Key facts

▪SPEC CPU2026 consists of 52 workloads, up from 43 in SPEC CPU2017.
▪The reference score for SPEC CPU2026 is based on the Ampere eMAG 8180 system, which is slower than many modern CPUs.
▪Initial tests indicate that Intel and AMD's latest CPUs perform similarly in integer tests, with Zen 5 excelling in floating point workloads.

Opening excerpt (first ~120 words) tap to expand

Evaluating SPEC CPU2026Chester LamMay 23, 20261312ShareSPEC’s CPU benchmark suite has been a long established industry standard, and is almost impossible to miss when reading through various publications. Intel used SPEC CPU2000 to showcase Pentium 4’s improvements over Pentium III. Samsung used SPEC CPU2000 and SPEC CPU2006 traces to tune their Mongoose cores. SPEC CPU2017 formed part of Intel’s performance projections for Lion Cove. Now, SPEC has updated their CPU benchmark suite with SPEC CPU2026. The new suite consists of 52 workloads, up from 43 in SPEC CPU2017. Individual workloads consist of more source code lines, measured in KLOC (thousands of lines of code).
