Intel Arc G3 vs Intel Core Ultra 7 270K Plus Comparison

The Verdict

The Intel Arc G3 and the Intel Core Ultra 7 270K Plus serve completely different market segments. The Arc G3 is a mobile processor with 14 cores and 14 threads, a 25 W TDP, and a boost clock of 4.60 GHz. The Core Ultra 7 270K Plus is a desktop part with 24 cores and 24 threads, a 125 W TDP, and a boost clock of 5.50 GHz. The data shows a decisive performance gap: the Ultra 7 270K Plus sits at the 96th percentile of all CPUs, while the Arc G3 is at the 50th percentile. The Arc G3 has no recorded benchmark scores, whereas the Ultra 7 270K Plus has an average benchmark score of 93785. Buyers should choose the Ultra 7 270K Plus for any sustained, high-thread-count workload, and the Arc G3 only when the priority is a low-power mobile platform with integrated graphics. The Ultra 7 270K Plus is the only one of the two with any measured performance data in the database.

Where Each One Wins

The Intel Core Ultra 7 270K Plus wins on every measurable benchmark category. The data shows its Cinebench R23 multicore score is 44253, its Cinebench R20 multicore score is 24461, and its Cinebench R15 multicore score is 6656. Single-core performance is equally strong: Cinebench R23 single-core at 2439, Cinebench R20 single-core at 3453, and Cinebench R15 single-core at 354. PassMark results are substantial across the board: multithread at 68574, single-thread at 5068, integer math at 175986, floating-point math at 229491, extended instructions at 63506, data compression at 804322, data encryption at 59097, find prime numbers at 615, random string sorting at 96945, and physics at 4064. The Arc G3 has no recorded benchmark scores, so it cannot claim a win in any measured workload. Its qualitative advantages are its 25 W TDP versus 125 W, its mobile market segment, and its lower boost clock of 4.60 GHz versus 5.50 GHz.

Head-to-Head Benchmarks

The database shows no direct head-to-head benchmark entries between the Arc G3 and the Ultra 7 270K Plus, and the Arc G3 has zero recorded individual benchmark scores. The comparison therefore relies entirely on the Ultra 7 270K Plus's measured results and the Arc G3's absence of data. The largest single measured win for the Ultra 7 270K Plus is in PassMark data compression at 804322, followed by floating-point math at 229491 and integer math at 175986. In Cinebench, the multicore R23 score of 44253 is roughly 18 times the R23 single-core score of 2439, showing strong scaling across its 24 cores. The R20 multicore score of 24461 versus the R20 single-core score of 3453 shows a similar ratio. The PassMark multithread score of 68574 versus the single-thread score of 5068 indicates the thread scaling holds up in synthetic integer workloads as well. The Cinebench R15 results show 6656 multicore and 354 single-core. In the nearest rival comparison, the Ultra 7 270K Plus's average score of 93785 is essentially tied with the Intel Xeon 6520P at 93786 with a delta of 0%, and it trails the AMD EPYC 4564P by 1.5%, the AMD EPYC 9175F by 1.9%, and the AMD EPYC 4565P by 2.1%. Those deltas are small, meaning the Ultra 7 270K Plus performs at the level of server-class Xeon and EPYC parts in the aggregate benchmark score, despite being a desktop processor. The Arc G3 has no score to place against those rivals or against the Ultra 7 270K Plus.
