SPEC released its first benchmark suite since 2017, naming it SPEC CPU2026. The new collection expands to 52 workloads from 43, each with larger code bases measured in thousands of lines. SPEC’s intent is to modernize the test while keeping the portability that made the suite a de‑facto standard for CPU performance reporting. Manufacturers still cite SPEC results when touting generational gains.

Testing on Linux with GCC 14.2 -O3 shows modern desktop cores crushing the reference platform. An Ampere eMAG 8180 scores the baseline 1.0, yet even a decade‑old FX‑8350 outpaces it in integer tests like 706.stockfish. Intel’s Core i7‑12700 and AMD’s Zen 5 deliver comparable integer scores, while Zen 5 pulls ahead on floating‑point workloads thanks to AVX‑512 generated by GCC. Clock speed variations still influence final rankings significantly.

IPC analysis reveals a tighter distribution in the integer suite than SPEC CPU2017, matching Geekbench 6’s focus on core throughput. Low‑IPC cases now stem mainly from frontend latency in branch‑heavy code such as 721.gcc, while high‑IPC workloads like 750.sealcrypto approach three instructions per cycle. Overall, the suite stresses cache hierarchy. The data confirms SPEC CPU2026 provides a clearer picture of modern CPU strengths and bottlenecks.
