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.

Verdict
Intel Xeon 6736P
8.6 / 10 Expert Rating
The Intel Xeon 6736P is the throughput-leaning 36-core Granite Rapids part, best for scale-out HPC and simulation work that values core count over per-core clock speed.
Intel Xeon 6740E
8.6 / 10 Expert Rating
The Intel Xeon 6740E trades per-core performance for AMD-style core density, a strong pick for horizontally-scaled cloud-native fleets.
