Intel Arc G3 vs Intel Core Ultra 9 285T Comparison

Where Each One Wins

The Intel Arc G3 and Intel Core Ultra 9 285T occupy completely different segments of the processor market, and the data reflects that split. The Arc G3 is a mobile part with 14 cores and 14 threads, built for a BGA 2540 socket, while the Ultra 9 285T is a desktop processor with 24 cores and 24 threads on Socket 1851. This is not a head-to-head comparison in the traditional sense; it is a question of platform and workload.

The Ultra 9 285T wins every recorded benchmark category. It has a complete set of benchmark scores across Cinebench R15, R20, R23, and Passmark tests, while the Arc G3 has no recorded benchmark scores in the database. This means the Ultra 9 285T is the only one of the two with measurable performance data. The Arc G3's percentile rank is 50, while the Ultra 9 285T sits at the 91st percentile of all CPUs in the database.

The use-case split is straightforward. The Ultra 9 285T is the choice for any task that requires heavy multi-threaded processing, given its 24 cores and 24 threads. It also handles single-threaded work with a boost clock of 5.40 GHz. The Arc G3, with a 25 W TDP and mobile socket, is designed for power-constrained laptops, not for benchmark-topping performance. Its 14 cores and 14 threads with a 4.60 GHz boost clock are sufficient for mainstream mobile workloads, but the database shows no evidence that it can compete with the desktop part in raw throughput.

For builders, the message is clear: if the task is desktop productivity, content creation, or any multi-core heavy workload, the Ultra 9 285T is the only option with data to support it. The Arc G3 is a mobile processor for portable systems where power efficiency matters more than absolute performance. The wins are one-sided because the database only has measurements for one of them.

Architecture Differences

The two processors are built on fundamentally different architectures. The Arc G3 uses the Panther Lake codename and belongs to the Arc G3 generation. Its process node is 3 nm, and the foundry is Intel. The Ultra 9 285T uses the Arrow Lake architecture with the Arrow Lake-S codename, placing it in the Core Ultra Series 2 generation. It is also on a 3 nm node, but the foundry is TSMC, not Intel. This is a significant divergence in manufacturing approach.

The transistor count and die size are only recorded for the Ultra 9 285T, which has 17,800 million transistors on a 243 mm² die. The Arc G3 has no transistor or die size data in the database, so a direct comparison is not possible. Cache configurations differ notably. Both have 192 KB of L1 cache per core, but the L2 cache differs: the Arc G3 has 2.5 MB per core, while the Ultra 9 285T has 3 MB per core. The L3 cache is a major split, with the Arc G3 offering 18 MB shared versus 36 MB shared on the Ultra 9 285T.

Memory support is another differentiator. The Arc G3 uses LPDDR5X with dual-channel support and a memory bandwidth of 136.5 GB/s. The Ultra 9 285T uses DDR5, also dual-channel, but with a lower memory bandwidth of 102.4 GB/s. ECC memory is supported on the Ultra 9 285T but not on the Arc G3. PCIe lanes also differ: the Arc G3 has Gen 5 with 4 lanes (CPU only), while the Ultra 9 285T has Gen 5 with 20 lanes (CPU only). This gives the desktop part significantly more expansion capability.

The integrated graphics are different as well. The Arc G3 includes Arc B370 graphics, while the Ultra 9 285T includes Arc Xe-LPG Graphics 64EU. The database does not provide benchmark scores for either iGPU, so this is a specification difference only.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Arc G3 and the Ultra 9 285T. The Arc G3 has no benchmark scores at all, so there are no direct comparisons to walk through. All recorded benchmark data belongs to the Ultra 9 285T.

The Ultra 9 285T's Cinebench scores are substantial. In Cinebench R15, it scores 3384 in multi-core and 477 in single-core. Cinebench R20 shows 14100 multi-core and 1990 single-core. Cinebench R23 delivers 33573 multi-core and 4739 single-core. These results place it in the 91st percentile of all CPUs.

Passmark tests reinforce the multi-threaded strength. The multi-thread score is 39931, single-thread is 4576, integer math is 132433, floating-point math is 137923, and extended instructions score 27477. Data compression reaches 384140, data encryption is 32061, find prime numbers scores 345, random string sorting is 47695, and physics is 2842.

Against its nearest rivals, the Ultra 9 285T's average benchmark score is 51310. The Intel Core i9-14900T scores 51015, a 0.6% delta in favor of the Ultra 9 285T. The Intel Core i9-13900F scores 51730, which is 0.8% higher than the Ultra 9 285T. The Intel Core i7-13850HX scores 50761, a 1.1% deficit to the Ultra 9 285T. The AMD Ryzen 9 5900XT scores 50718, a 1.2% deficit. The data shows the Ultra 9 285T is competitive with these desktop parts, sitting just below the i9-13900F and just above the other rivals.

Since the Arc G3 has no benchmark scores, the only meaningful comparison is that it cannot be measured against the Ultra 9 285T. The database indicates zero wins for either side in head-to-head tests, because no such tests exist.

The Verdict

The data supports a clear choice based on platform and workload. The Intel Core Ultra 9 285T is the only one of the two with recorded benchmark scores, and those scores are strong. It delivers a multi-core Cinebench R23 score of 33573 and a single-core score of 4739. Its average benchmark score of 51310 places it in the 91st percentile of all CPUs. It matches or beats most of its nearest rivals, with only the Intel Core i9-13900F ahead of it by 0.8%. For a desktop builder needing a 24-core, 24-thread processor with a 5.40 GHz boost clock, 36 MB of L3 cache, ECC memory support, and 20 PCIe Gen 5 lanes, the Ultra 9 285T is the data-backed selection. Its launch MSRP is $549.

The Intel Arc G3 is a mobile part with a 25 W TDP and 14 cores. It has no benchmark scores in the database, so there is no performance data to evaluate. It uses a 3 nm Intel process, LPDDR5X memory with higher bandwidth than the desktop part, and a smaller 18 MB L3 cache. It is for a portable system where the 25 W TDP and BGA 2540 socket are appropriate. Anyone building a desktop should choose the Ultra 9 285T. Anyone buying a laptop with a Panther Lake mobile processor will get a capable part, but the database cannot quantify its performance. The verdict, strictly from the recorded data, is that the Ultra 9 285T is the only one with measurable performance, and that performance is competitive at the top of the desktop field.
