The Arc G3 EXTREME is the better choice for workloads that depend on single-thread responsiveness, encryption, physics calculations, and extended instruction sets. Its higher memory bandwidth of 136.5 GB/s and larger per-core L1 and L2 caches likely contribute to these wins. The Core 7 251TE is better suited for heavily threaded workloads, integer-heavy tasks, and compression workloads where its 24 cores, 32 threads, and 36 MB of L3 cache provide a structural advantage.

The Verdict

The data presents two clearly different processors for different jobs. The Intel Core 7 251TE is the higher-scoring processor overall, with an average benchmark score of 41650 versus 36699 for the Arc G3 EXTREME. It also holds the 88th percentile ranking versus the 85th for the Arc G3 EXTREME.

The Core 7 251TE should be the pick for users running multi-threaded productivity workloads. Its Cinebench R23 multi-core score of 25518 is 42.6% ahead of the Arc G3 EXTREME, and its integer math score of 125739 is 43.4% ahead. Compression and sorting workloads also favor it, with leads of 8.2% and 5.8% respectively. The 24 cores, 32 threads, 5.40 GHz boost clock, and 36 MB of L3 cache make it the stronger compute engine for parallel tasks.

The Arc G3 EXTREME is the pick for workloads that stress instruction-level parallelism, prime number calculation, physics, and single-thread PassMark performance. It leads by 77.1% in prime numbers, 41.5% in extended instructions, 29.8% in physics, and 20.3% in single-thread PassMark. Its 3 nm process node, 136.5 GB/s memory bandwidth, and larger per-core cache hierarchy support these strengths. The 25 W TDP also makes it suitable for constrained thermal environments in mobile systems.

The Core 7 251TE wins the Cinebench single-core tests decisively, but the Arc G3 EXTREME wins the PassMark single-thread test. This split suggests the two respond differently to specific benchmark methodologies. Users should match the benchmark profile to their actual workload rather than relying on a single test.

For desktop builders needing maximum multi-core throughput and ECC memory support, the Core 7 251TE is the data-backed choice. For mobile users or those prioritizing encryption, physics, and instruction-heavy single-thread tasks, the Arc G3 EXTREME delivers the better benchmark results.
