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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the Intel Core Ultra 9 285K wins all 17 head-to-head benchmark comparisons against the Intel Arc G3 EXTREME. No benchmark in the database favors the Arc G3 EXTREME. The largest deltas appear in heavily multithreaded workloads, while the smallest gaps occur in single-thread tests.

In Cinebench R23 multi-core, the Ultra 9 285K scores 42,522 against 14,655 for the Arc G3 EXTREME, a delta of -65.5%. That is the widest margin in the Cinebench suite. Cinebench R15 multi-core shows a similar pattern: 6,494 versus 2,192, a -66.2% delta. The R20 multi-core result is 24,003 versus 10,945, a -54.4% gap. These numbers indicate that the desktop part delivers roughly three times the multi-threaded rendering throughput of the mobile part in the older R15 test, and just under two and a half times in R20.

Single-core results are closer but still favor the Ultra 9 285K. In Cinebench R23 single-core, the Ultra 9 scores 2,377 against 1,862, a -21.7% delta. Cinebench R20 single-core shows 3,388 versus 1,545, a -54.4% delta. Cinebench R15 single-core is 359 versus 267, a -25.6% delta. PassMark single-thread tests show the smallest overall gap: 5,087 versus 4,293, a -15.6% delta. The single-thread advantage is real but far less dramatic than the multi-core advantage, which aligns with the difference in boost clocks and core counts.

PassMark workloads reinforce the pattern. Data compression shows 790,052 versus 307,094, a -61.1% delta. Data encryption is 57,745 versus 23,881, a -58.6% delta. Extended instructions score 62,277 versus 24,017, a -61.4% delta. Floating point math is 224,324 versus 86,929, a -61.2% delta. Integer math is 172,379 versus 71,164, a -58.7% delta.

Architecture Differences

The two processors come from different market segments and use different physical designs. The Intel Arc G3 EXTREME is a mobile part on the Panther Lake platform, built on Intel's 3 nm process at Intel foundries. It uses the Intel BGA 2540 socket. The Intel Core Ultra 9 285K is a desktop part in the Core Ultra Series 2, built on the Arrow Lake architecture and codename Arrow Lake-S, also on a 3 nm process but fabricated by TSMC. It uses Intel Socket 1851.

The Arc G3 EXTREME has 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The Ultra 9 285K has 24 cores and 24 threads, with a base clock of 3.70 GHz and a boost clock of 5.70 GHz. The desktop part has a 125 W TDP, while the mobile part has a 25 W TDP. The Ultra 9 285K is multiplier unlocked; the Arc G3 EXTREME is not.

Cache configurations differ. Both parts have 192 KB of L1 cache per core. The L2 cache is 2.5 MB per core on the Arc G3 EXTREME and 3 MB per core on the Ultra 9 285K. L3 cache is 18 MB shared on the mobile part versus 36 MB shared on the desktop part. The Ultra 9 285K also lists 17,800 million transistors and a 243 mm² die size; the Arc G3 EXTREME lists no transistor count or die size in the database.

Memory support differs by platform. The Arc G3 EXTREME supports LPDDR5X memory with dual-channel access and 136.5 GB/s bandwidth. The Ultra 9 285K supports DDR5 with dual-channel access and 102.4 GB/s bandwidth. The mobile part has higher recorded memory bandwidth despite being the lower-performing CPU overall. ECC memory is supported on the Ultra 9 285K but not on the Arc G3 EXTREME.

PCIe connectivity is also different. The Arc G3 EXTREME provides Gen 5 with 4 lanes (CPU only). The Ultra 9 285K provides Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well: the Arc G3 EXTREME uses Arc B390 graphics, while the Ultra 9 285K uses Arc Xe-LPG Graphics 64EU.

Release dates are recorded as 2026-05-27 for the Arc G3 EXTREME and 2024-10-23 for the Ultra 9 285K. Both are listed as Active in production status. The Ultra 9 285K has a launch MSRP of $589. The Arc G3 EXTREME has no launch MSRP recorded.

The Verdict

The data supports one clear conclusion: the Intel Core Ultra 9 285K is the stronger processor in every measured workload. It wins all 17 head-to-head benchmarks, holds a 96th percentile ranking versus 85th for the Arc G3 EXTREME, and averages more than double the benchmark score. The desktop part's 24 cores, 5.70 GHz boost clock, 36 MB L3 cache, and 125 W TDP combine to deliver margins between -15.6% and -66.2% across the database's benchmark suite.

The Arc G3 EXTREME does have advantages in the recorded specifications, but they do not translate into benchmark wins. Its LPDDR5X memory support gives it higher memory bandwidth at 136.5 GB/s versus 102.4 GB/s. Its 25 W TDP indicates a far lower power envelope, consistent with mobile use. Its 18 MB L3 cache and 2.5 MB per-core L2 cache are smaller than the desktop part's 36 MB and 3 MB per-core figures, but the mobile part still achieves the 85th percentile overall.

For workloads that rely on raw multi-threaded throughput, single-thread speed, compression, encryption, floating point math, integer math, physics, or sorting, the Ultra 9 285K is the choice indicated by the data. The Arc G3 EXTREME's role is defined by its platform characteristics, not by winning any benchmark in the database. Users constrained to a mobile platform with LPDDR5X memory and a lower TDP would use the Arc G3 EXTREME; users seeking maximum recorded performance would select the Ultra 9 285K.

Specification Differences

The two parts differ across nearly every major specification field. The Arc G3 EXTREME has 14 cores and 14 threads; the Ultra 9 285K has 24 cores and 24 threads. Base clocks are 1.90 GHz versus 3.70 GHz. Boost clocks are 4.70 GHz versus 5.70 GHz. TDP is 25 W versus 125 W. The socket is Intel BGA 2540 versus Intel Socket 1851.

Architecture and codename also differ: the Arc G3 EXTREME uses Panther Lake with no separate architecture name recorded, while the Ultra 9 285K uses Arrow Lake with the codename Arrow Lake-S. Both use a 3 nm process node, but the foundry is Intel for the Arc G3 EXTREME and TSMC for the Ultra 9 285K. The desktop part records 17,800 million transistors and a 243 mm² die size; the mobile part records neither.

Cache differs: L1 is 192 KB per core on both, but L2 is 2.5 MB per core versus 3 MB per core, and L3 is 18 MB shared versus 36 MB shared. Memory support is LPDDR5X versus DDR5, with memory bandwidth of 136.5 GB/s versus 102.4 GB/s. ECC memory is false on the Arc G3 EXTREME and true on the Ultra 9 285K. PCIe is Gen 5 with 4 lanes versus Gen 5 with 20 lanes, both CPU only. Integrated graphics are Arc B390 versus Arc Xe-LPG Graphics 64EU. Market segment is Mobile versus Desktop. The Ultra 9 285K is multiplier unlocked; the Arc G3 EXTREME is not. Release dates are 2026-05-27 versus 2024-10-23. The Ultra 9 285K has a launch MSRP of $589; the Arc G3 EXTREME has no recorded MSRP.

Where Each One Wins

The Intel Core Ultra 9 285K wins every benchmark category in the database. In rendering workloads, Cinebench R15, R20, and R23 multi-core tests all show the desktop part ahead by margins from -54.4% to -66.2%. Single-core rendering also favors the Ultra 9 285K, with deltas from -21.7% to -54.4%. PassMark data compression, encryption, extended instructions, prime finding, floating point math, integer math, multithread, physics, random string sorting, and single-thread tests all record the Ultra 9 285K as the winner.

The Arc G3 EXTREME has no benchmark wins in the database. Its recorded advantages are specification-level only. It offers higher memory bandwidth at 136.5 GB/s, a lower 25 W TDP, a smaller physical footprint implied by the BGA socket, and LPDDR5X memory support. These features position it for mobile platforms where power and memory type matter more than absolute performance. The database's percentile ranking places it at 85th overall, which indicates competitive standing against mainstream desktop and mobile CPUs, but not against the Ultra 9 285K's 96th percentile tier.

The use-case split is therefore structural rather than performance-based. The Ultra 9 285K is the part for any workload measured in the database: rendering, compression, encryption, math, sorting, physics, and single-thread tasks. The Arc G3 EXTREME is the part for a mobile platform with LPDDR5X memory and a 25 W envelope, where its 14 cores and 4.70 GHz boost still place it in the 85th percentile of all CPUs. The recorded data does not show any scenario where the mobile part outperforms the desktop part.
