AMD Ryzen 9 270 vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen 9 270 and Intel Arc G3 EXTREME are two mobile processors with contrasting designs and benchmark profiles. The recorded data shows a clear split between multi-threaded workloads and specific math or single-thread tasks. The Ryzen 9 270 wins 10 of the 17 head-to-head benchmarks, while the Arc G3 EXTREME takes 7, but the margin of victory in each category tells a more detailed story than the raw win count.

Head-to-Head Benchmarks

The most decisive results appear in the Cinebench suite. In Cinebench R23 multi-core, the AMD Ryzen 9 270 scores 26438 against 14655 for the Intel Arc G3 EXTREME, a delta of 80.4%. The single-core R23 test is even more lopsided: the Ryzen 9 270 posts 3732 versus 1862, a 100.4% advantage. These are the largest deltas in the entire comparison. Cinebench R15 shows a similar pattern, with the Ryzen 9 270 leading by 21.5% in multi-core (2664 vs 2192) and by 40.8% in single-core (376 vs 267). Cinebench R20 results are much closer, with the Ryzen 9 270 ahead by only 1.4% in both multi-core (11103 vs 10945) and single-core (1567 vs 1545).

PassMark results reveal a different balance. The Intel Arc G3 EXTREME wins PassMark single-thread with a score of 4293 versus 3784, an 11.9% margin, and this result is duplicated in the PassMark singlethread entry. The Arc G3 EXTREME also leads in floating point math (86929 vs 60122, a 30.8% advantage), in find prime numbers (248 vs 88, a 64.5% margin), and in physics (2515 vs 1365, a 45.7% lead). The PassMark multithread test goes to Intel as well, with 30659 versus 29089, a 5.1% edge.

The AMD Ryzen 9 270 answers with strong PassMark wins in integer math (98266 vs 71164, a 38.1% margin), data compression (351398 vs 307094, a 14.4% lead), random string sorting (42819 vs 37331, a 14.7% edge), and extended instructions (26729 vs 24017, an 11.3% advantage). The Intel Arc G3 EXTREME takes the data encryption test with 23881 against 20852, a 12.7% margin. The overall average benchmark score favors the Ryzen 9 270 at 40246, while the Arc G3 EXTREME sits at 36699. The Ryzen 9 270 ranks in the 87th percentile of all CPUs, and the Arc G3 EXTREME ranks in the 85th.

Architecture Differences

The two processors are built on fundamentally different designs. The AMD Ryzen 9 270 uses the Zen 4 architecture under the Hawk Point codename, fabricated on a 4 nm process at TSMC. It packs 8 cores and 16 threads, with a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Intel Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process at Intel, with 14 cores and 14 threads, a base clock of 1.90 GHz, and a boost clock of 4.70 GHz. The lack of simultaneous multithreading on the Intel part explains the 14 threads matching 14 cores.

Cache layouts also diverge sharply. The Ryzen 9 270 provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Arc G3 EXTREME offers 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has more cache per core and a larger L3 pool, but the AMD part compensates with higher clock speeds and simultaneous multithreading.

Memory support differs as well. The Ryzen 9 270 supports DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth. The Arc G3 EXTREME supports LPDDR5X on a dual-channel bus with 136.5 GB/s of bandwidth. The Intel platform delivers 52.4% more memory bandwidth in the recorded specifications. PCIe connectivity also differs: the Ryzen 9 270 uses Gen 4 with 20 lanes, while the Arc G3 EXTREME uses Gen 5 with 4 lanes. Neither processor supports ECC memory, and both have their multipliers locked.

The integrated graphics differ by vendor and naming. The Ryzen 9 270 carries a Radeon 780M, while the Arc G3 EXTREME carries an Arc B390. Both are mobile parts with active production status. The Ryzen 9 270 was released on 2025-01-05, and the Arc G3 EXTREME on 2026-05-27. The Ryzen 9 270 uses AMD Socket FP8, and the Arc G3 EXTREME uses Intel BGA 2540. The Ryzen 9 270 has a TDP of 45, and the Arc G3 EXTREME has a TDP of 25. The Ryzen 9 270 die measures 178 mm² and contains 25,000 million transistors; the Arc G3 EXTREME has no recorded die size or transistor count.

The Verdict

The benchmark data points to the AMD Ryzen 9 270 as the stronger processor for Cinebench-style rendering workloads. It leads in every Cinebench test, with margins ranging from 1.4% in R20 up to 100.4% in R23 single-core.

Where Each One Wins

The AMD Ryzen 9 270 is the choice for Cinebench rendering workloads. It wins all three Cinebench versions and both single-core and multi-core variants within them. The R23 single-core margin of 100.4% and the R23 multi-core margin of 80.4% are the dominant results in the comparison. The Ryzen 9 270 also wins PassMark integer math, data compression, random string sorting, and extended instructions, which points to strong general-purpose integer performance and data handling.

The Intel Arc G3 EXTREME is the choice for PassMark physics, floating point math, find prime numbers, and data encryption. Its 45.7% physics lead and 64.5% find prime numbers lead are substantial. The single-thread PassMark win by 11.9% shows an advantage in lightly threaded scenarios, despite the lower boost clock. The higher memory bandwidth of 136.5 GB/s and the 3 nm process node are architectural advantages that appear in the recorded specifications, even if they do not translate to wins in the Cinebench suite.

The overall average benchmark score favors the AMD Ryzen 9 270 at 40246, and its 87th percentile ranking is two points above the Arc G3 EXTREME's 85th. The data does not support a single universal winner; instead, the two processors serve different workload profiles. Rendering and integer-heavy tasks lean toward the Ryzen 9 270, while floating point, physics, encryption, and single-thread PassMark tasks lean toward the Arc G3 EXTREME.
