Intel Arc G3 EXTREME vs Intel Core Ultra 9 285T Comparison

The Verdict

The recorded data presents a complete sweep. The Intel Core Ultra 9 285T wins all 17 head-to-head benchmark comparisons against the Intel Arc G3 EXTREME. The margin is substantial. In the Cinebench R23 multi-core test, the Ultra 9 285T records 33573 points against 14655 for the Arc G3 EXTREME, a 56.3% advantage. The single-core gap is even larger, with a 60.7% delta in Cinebench R23.

The database percentile ranking confirms this separation. The Core Ultra 9 285T sits at the 91st percentile of all CPUs, while the Arc G3 EXTREME ranks at the 85th percentile. The average benchmark scores differ accordingly: 51310 for the Ultra 9 285T versus 36699 for the Arc G3 EXTREME. The nearest rivals for each part show where they sit in the broader market. The Ultra 9 285T sits within 1.2% of the AMD Ryzen 9 5900XT and 1.1% of the Intel Core i7-13850HX. The Arc G3 EXTREME sits within 1.1% of the AMD Ryzen AI 7 PRO 450 and 0.9% of the AMD Ryzen 5 5500X3D.

The choice from this data is clear. The Ultra 9 285T is the higher-performing processor across every measured workload. The Arc G3 EXTREME, despite being a mobile part with a 25 TDP, cannot match the desktop-oriented 35 TDP part. The data indicates that any workload requiring multi-threaded throughput, single-thread responsiveness, or memory intensive operations belongs to the Ultra 9 285T.

Architecture Differences

The two processors come from different Intel lineups and foundries. The Arc G3 EXTREME uses the Panther Lake codename, built on a 3 nm process at Intel's own foundry. The Core Ultra 9 285T uses the Arrow Lake-S codename, also on a 3 nm process, but fabricated by TSMC. The core counts differ substantially: the Arc G3 EXTREME has 14 cores and 14 threads, while the Ultra 9 285T has 24 cores and 24 threads. Neither part enables simultaneous multithreading.

The cache hierarchy shows notable differences. Both parts have 192 KB of L1 per core. The L2 cache differs, with the Arc G3 EXTREME at 2.5 MB per core and the Ultra 9 285T at 3 MB per core. The L3 cache is the biggest split: 18 MB shared on the Arc G3 EXTREME versus 36 MB shared on the Ultra 9 285T. The Ultra 9 285T carries 17,800 million transistors on a 243 mm² die, while the database does not list transistor or die size data for the Arc G3 EXTREME.

The integrated graphics differ as well. The Arc G3 EXTREME includes Arc B390 graphics. The Ultra 9 285T includes Arc Xe-LPG Graphics with 64 execution units. Memory support also diverges: the Arc G3 EXTREME uses LPDDR5X with a dual-channel bus and 136.5 GB/s bandwidth. The Ultra 9 285T uses DDR5 with a dual-channel bus and 102.4 GB/s bandwidth. The Ultra 9 285T supports ECC memory, while the Arc G3 EXTREME does not.

The sockets and PCIe configurations reflect their market segments. The Arc G3 EXTREME uses Intel BGA 2540, a mobile socket, with PCIe Gen 5 limited to 4 lanes. The Ultra 9 285T uses Intel Socket 1851, a desktop socket, with PCIe Gen 5 across 20 lanes. The Arc G3 EXTREME belongs to the mobile market segment, while the Ultra 9 285T is a desktop part.

Head-to-Head Benchmarks

The benchmark data shows a consistent pattern across all 17 tests. The smallest margin comes in PassMark single-thread tests. The Ultra 9 285T scores 4576 against 4293 for the Arc G3 EXTREME, a 6.2% delta. That narrow gap still favors the desktop part, but it suggests the mobile processor holds up better in lightly threaded tasks.

Where Each One Wins

The data shows no benchmark wins for the Arc G3 EXTREME. Every recorded test favors the Ultra 9 285T. The use-case split therefore depends on factors outside the benchmark results, such as market segment and platform constraints.

The Arc G3 EXTREME targets the mobile segment. It uses a BGA 2540 socket, has a 25 TDP, and supports LPDDR5X memory. Its integrated graphics are Arc B390. The database shows it ranks at the 85th percentile, with average scores comparable to the AMD Ryzen AI 7 PRO 450 and the AMD Ryzen 5 5500X3D. For mobile workloads where power draw and socket compatibility matter, the Arc G3 EXTREME is the only option of the two, since the Ultra 9 285T requires a desktop socket.

The Ultra 9 285T targets the desktop segment. It uses Socket 1851, has a 35 TDP, and supports DDR5 memory with ECC. Its integrated graphics are Arc Xe-LPG Graphics with 64 execution units. The data confirms it outperforms the Arc G3 EXTREME in every workload category: Cinebench rendering, PassMark math operations, encryption, compression, and sorting. The 60.7% single-core advantage and 56.3% multi-core advantage in Cinebench R23 indicate that both lightly threaded and heavily threaded applications will run faster on the Ultra 9 285T.

The only scenario where the Arc G3 EXTREME appears preferable is when the mobile form factor and BGA socket are mandatory, or when the lower 25 TDP is a hard constraint. In those cases, the Arc G3 EXTREME still delivers competitive performance relative to its nearest rivals, sitting within 1.1% of the AMD Ryzen AI 7 PRO 450. For any desktop build where socket and power constraints allow the Ultra 9 285T, the benchmark data shows no reason to choose the Arc G3 EXTREME. The Ultra 9 285T also provides more PCIe lanes (20 versus 4) and a higher boost clock (5.40 GHz versus 4.70 GHz), which supports expansion and peak single-thread performance. The core count difference of 24 versus 14 gives the Ultra 9 285T a structural advantage in parallel workloads, and the larger L3 cache (36 MB versus 18 MB) supports that advantage. The data does not show any workload where the Arc G3 EXTREME closes the gap to a competitive margin.
