Benchmarks
Measured results, not specifications. Percentages are the gap to the leading product in each test.
SPECrate® 2017 Integer (base), 1-chip
Best published 1-chip result on spec.org, retrieved 23 Sept 2026.
SPECrate 2017 Integer runs ten integer workloads, including a compiler, file compression, a chess engine and route planning, with one copy per hardware thread. The score is throughput against a fixed reference machine, so it reflects multi-core server and workstation work rather than gaming. Each figure is the best result a hardware vendor published on spec.org for a one-chip system, so the server, memory and compiler behind each chip differ.
SPECrate® 2017 Floating Point (base), 1-chip
Best published 1-chip result on spec.org, retrieved 23 Sept 2026.
SPECrate 2017 Floating Point runs thirteen scientific and engineering workloads, including weather and climate models, fluid dynamics, molecular dynamics and ray tracing, with one copy per hardware thread. It rewards core count, vector units and memory bandwidth, which is why server chips with many memory channels lead it. Each figure is the best result a hardware vendor published on spec.org for a one-chip system, so the server, memory and compiler behind each chip differ.
