Intel Arc G3 vs Intel Core Ultra 5 245T Comparison

# Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the Intel Arc G3 and the Intel Core Ultra 5 245T. However, benchmark data exists for the Core Ultra 5 245T across multiple Cinebench and Passmark tests, while the Arc G3 has no recorded benchmark scores at all. This asymmetry means the comparison relies on the Core Ultra 5 245T's measured performance profile and the architectural characteristics of both parts.

The Core Ultra 5 245T delivers a Cinebench R23 multi-core score of 26208 and a single-core score of 3699. Its Cinebench R20 results show 11007 multi-core and 1553 single-core, while Cinebench R15 records 2641 multi-core and 372 single-core. Passmark results include a multi-thread score of 30833, a single-thread score of 4367, integer math at 88676, floating point math at 108499, and extended instructions at 22071. Data compression reaches 283812, data encryption hits 23656, physics scores 2278, find prime numbers scores 324, and random string sorting scores 34931.

The Core Ultra 5 245T holds an 86th percentile rank among all CPUs in the database, with an average benchmark score of 38194. Its nearest rivals include the AMD Ryzen 7 250 at 38221, which is 0.1% behind, and the Intel Core i5-13600HX at 38261, which is 0.2% behind. The Intel Core i5-14490F scores 38149, putting the Core Ultra 5 245T 0.1% ahead, and the Intel Core i5-13600KF scores 38103, with the Core Ultra 5 245T 0.2% ahead. These margins are narrow, placing the Core Ultra 5 245T in a tightly contested performance band.

Because the Arc G3 has no benchmark entries, its percentile rank sits at 50 with an average score of 0. The absence of measured data prevents any direct numeric comparison of performance wins between the two processors. The Core Ultra 5 245T clearly carries all recorded benchmark results, while the Arc G3 remains an unmeasured entry in the database.

# Architecture Differences

The Intel Arc G3 uses the Panther Lake codename and belongs to the Arc G3 generation, built on Intel's 3 nm process node at Intel's own foundry. The Intel Core Ultra 5 245T uses the Arrow Lake-S codename and the Core Ultra Series 2 family, also built on a 3 nm process node but fabricated by TSMC. Both processors contain 14 cores and 14 threads, so neither uses simultaneous multithreading.

The Arc G3 is a mobile-market part with a TDP of 25 watts, whereas the Core Ultra 5 245T is a desktop-market part with a TDP of 65 watts. Clock speeds differ: the Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz, while the Core Ultra 5 245T runs at 2.20 GHz base and 5.10 GHz boost. The Core Ultra 5 245T holds a higher boost clock by 0.50 GHz and a higher base clock by 0.30 GHz.

Cache configurations differ in L2 and L3 capacity. The Arc G3 provides 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core Ultra 5 245T also provides 192 KB of L1 per core but increases L2 to 3 MB per core and L3 to 24 MB shared. The Core Ultra 5 245T therefore holds 0.5 MB more L2 per core and 6 MB more L3 total.

Memory support diverges significantly. The Arc G3 supports LPDDR5X memory over a dual-channel bus with 136.5 GB/s of bandwidth. The Core Ultra 5 245T supports DDR5 memory over a dual-channel bus with 102.4 GB/s of bandwidth. ECC memory support is absent on the Arc G3 but present on the Core Ultra 5 245T. PCIe connectivity also differs: the Arc G3 offers Gen 5 with 4 lanes, while the Core Ultra 5 245T offers Gen 5 with 20 lanes.

Integrated graphics differ as well. The Arc G3 includes Arc B370 graphics, while the Core Ultra 5 245T includes Arc Xe-LPG Graphics with 64 execution units. Sockets are not interchangeable: the Arc G3 uses Intel BGA 2540, a soldered mobile socket, while the Core Ultra 5 245T uses Intel Socket 1851 for desktop installations.

The Core Ultra 5 245T carries additional recorded physical details: 17,800 million transistors and a die size of 243 mm². The Arc G3 has no transistor count or die size recorded. The Core Ultra 5 245T's part number is SRVFF, while the Arc G3 uses SA4QZ. Neither processor has an unlocked multiplier.

# Where Each One Wins

The recorded data gives the Core Ultra 5 245T a clear set of strengths in measured workloads. Its Cinebench R23 multi-core score of 26208 and single-core score of 3699 indicate strong performance in both heavily threaded and lightly threaded tasks. Passmark single-thread performance at 4367 confirms that single-core responsiveness is a notable asset. The Core Ultra 5 245T also shows high throughput in integer math at 88676 and floating point math at 108499, making it suited to compute-heavy workloads that rely on arithmetic performance.

Data-oriented tasks favor the Core Ultra 5 245T. The Passmark data compression score of 283812 and data encryption score of 23656 indicate solid handling of compression and encryption workloads. Extended instructions score 22071, suggesting capable SIMD and specialized instruction execution. Random string sorting at 34931 and find prime numbers at 324 round out the measured workload profile.

The Arc G3, by contrast, has no recorded benchmark scores. Its advantages must be inferred from architecture alone. The Arc G3 uses a lower 25-watt TDP, which suits thermally constrained mobile environments. Its LPDDR5X memory support with 136.5 GB/s bandwidth provides more memory bandwidth than the Core Ultra 5 245T's 102.4 GB/s, which could benefit integrated graphics workloads that depend on memory throughput. The integrated Arc B370 graphics likely benefit from that higher bandwidth, though no measured graphics scores exist in the database.

The Arc G3 also carries a smaller L3 cache at 18 MB versus 24 MB, and less L2 per core at 2.5 MB versus 3 MB, so the Core Ultra 5 245T holds the cache advantage. The Core Ultra 5 245T's 20 PCIe Gen 5 lanes provide more expansion bandwidth than the Arc G3's 4 lanes, making the desktop part better suited to discrete GPUs and high-speed storage.

# The Verdict

The data records no benchmark results for the Intel Arc G3, so its measured performance cannot be compared directly to the Core Ultra 5 245T. The Core Ultra 5 245T, however, has a full set of Cinebench and Passmark scores and sits at the 86th percentile among all CPUs. Its average benchmark score of 38194 places it in a tight cluster with the AMD Ryzen 7 250, Intel Core i5-13600HX, Intel Core i5-14490F, and Intel Core i5-13600KF, all within 0.2% of each other.

For desktop workloads where measured performance matters, the Core Ultra 5 245T is the only one of the two with recorded data to support a decision. Its Cinebench R23 scores of 26208 multi-core and 3699 single-core, plus Passmark single-thread at 4367, indicate strong all-around processing capability. The 65-watt TDP and 20 PCIe Gen 5 lanes make it suitable for full desktop builds, and ECC memory support expands its applicability to error-sensitive environments.

For mobile or low-power scenarios, the Arc G3 offers a 25-watt TDP and LPDDR5X memory with 136.5 GB/s bandwidth, which is 34.1 GB/s more than the Core Ultra 5 245T. Its integrated Arc B370 graphics and mobile socket target compact systems, but without benchmark scores, its actual performance level remains unverified in the database.

The choice depends on workload context. The Core Ultra 5 245T is the measured performer with strong multi-core and single-core scores, higher clock speeds, more cache, more PCIe lanes, and ECC support. The Arc G3 is the power-efficient mobile option with higher memory bandwidth and a smaller physical footprint, but it lacks any recorded performance data to confirm its capabilities.
