Intel Arc G3 vs Intel Core Ultra 7 265T Comparison

Intel Arc G3 is a mobile processor with 14 cores, 14 threads, a base clock of 1.90 GHz, a boost clock of 4.60 GHz, and a 25 W TDP. Intel Core Ultra 7 265T is a desktop processor with 20 cores, 20 threads, a base clock of 1.50 GHz, a boost clock of 5.30 GHz, and a 35 W TDP. The Arc G3 sits at the 50th percentile of all CPUs in the database, while the Ultra 7 265T sits at the 90th percentile. The database contains no benchmark scores for the Arc G3, meaning all performance comparisons below rely on the recorded measurements for the Ultra 7 265T and its nearest rivals.

Head-to-Head Benchmarks

The database holds no direct head-to-head benchmark results between the Intel Arc G3 and the Intel Core Ultra 7 265T. The Arc G3 has no recorded benchmark scores, while the Ultra 7 265T has a full suite of Cinebench and PassMark results. The Ultra 7 265T delivers a Cinebench R23 multi-core score of 31558 and a single-core score of 4455. In Cinebench R20, it scores 13254 multi-core and 1871 single-core, and in Cinebench R15 it scores 3180 multi-core and 449 single-core. Its average benchmark score across all tests is 47697.

Because the Arc G3 lacks any measured scores, the only quantitative benchmark comparison available is the Ultra 7 265T against its nearest rivals. The Ultra 7 265T sits within a tight performance cluster: it is 0.4% ahead of the AMD Ryzen 9 PRO 5945 (average score 47527), 0.4% behind the AMD Ryzen 9 7900X3D (average score 47908), 0.5% behind the AMD Ryzen 9 3900 (average score 47918), and 0.5% ahead of the Intel Core Ultra X9 378H (average score 47468). These delta percentages are small, indicating that the Ultra 7 265T is statistically equivalent to these four processors in aggregate performance.

The PassMark results for the Ultra 7 265T show its strongest areas. It scores 370158 in data compression, 29687 in data encryption, 28609 in extended instructions, 322 in find prime numbers, 129817 in floating point math, 104943 in integer math, 37084 in multithread, 2391 in physics, 44400 in random string sorting, and 4338 in single thread. The single-thread score of 4338 appears twice in the database, once under the name "passmark_single_thread" and once under "passmark_singlethread".

Architecture Differences

The Intel Arc G3 belongs to the Panther Lake generation and uses Intel's 3 nm process node. It has 14 cores and 14 threads, with no hyperthreading, and its cache layout includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. It supports LPDDR5X memory on a dual-channel bus with 136.5 GB/s of bandwidth. The Arc G3 uses the Intel BGA 2540 socket, has an integrated Arc B370 GPU, and is classified as a mobile part. Its PCIe support is Gen 5 with 4 lanes (CPU only).

The Intel Core Ultra 7 265T belongs to the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-S codename, and is built on a 3 nm process node by TSMC. It has 20 cores and 20 threads, with 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. It supports DDR5 memory on a dual-channel bus with 102.4 GB/s of bandwidth, which is lower than the Arc G3's LPDDR5X bandwidth. The Ultra 7 265T uses the Intel Socket 1851, has an integrated Arc Xe-LPG Graphics 64EU, and is a desktop part. Its PCIe support is Gen 5 with 20 lanes (CPU only), a substantial increase over the Arc G3's 4 lanes. The Ultra 7 265T has 17,800 million transistors on a 243 mm² die, while the Arc G3 has no recorded transistor count or die size.

Both processors use 3 nm technology, but the foundries differ: Intel for the Arc G3, TSMC for the Ultra 7 265T. The Arc G3's L2 cache per core (2.5 MB) is smaller than the Ultra 7 265T's (3 MB). The Ultra 7 265T has a larger shared L3 (30 MB) compared to the Arc G3 (18 MB). Neither processor supports ECC memory, and both have locked multipliers.

Where Each One Wins

The Intel Core Ultra 7 265T has clear advantages based on recorded data. Its 20 cores and 20 threads outnumber the Arc G3's 14 cores and 14 threads, which directly supports higher multi-threaded throughput. Its boost clock of 5.30 GHz exceeds the Arc G3's 4.60 GHz, which helps single-threaded responsiveness. The Ultra 7 265T's larger L3 cache (30 MB vs 18 MB) and larger L2 per core (3 MB vs 2.5 MB) provide more on-die data capacity. Its 20 PCIe Gen 5 lanes versus 4 lanes on the Arc G3 gives the desktop part far more expansion headroom for discrete GPUs, storage, and other high-bandwidth devices.

The Intel Arc G3 holds advantages in specific areas. Its memory bandwidth is higher at 136.5 GB/s versus 102.4 GB/s for the Ultra 7 265T, which can benefit memory-intensive workloads despite the smaller cache. The Arc G3's TDP of 25 W is lower than the Ultra 7 265T's 35 W, indicating a more power-efficient design for mobile use. The Arc G3 uses LPDDR5X memory, which is typically more power-efficient than DDR5. Its integrated Arc B370 GPU is a separate product from the Ultra 7 265T's Arc Xe-LPG Graphics 64EU, and the database does not provide comparative graphics performance data.

The Arc G3's advantage lies in its mobile form factor and memory bandwidth, while the Ultra 7 265T's advantage lies in core count, clock speed, cache, and PCIe connectivity. The Ultra 7 265T's 90th percentile ranking versus the Arc G3's 50th percentile suggests the desktop part sits in a much stronger overall performance position in the database, though the Arc G3's lack of benchmark scores limits direct comparison.

The Verdict

The recorded data shows a clear split in intended use cases. The Intel Core Ultra 7 265T is the stronger desktop processor, with 20 cores versus 14, a higher boost clock (5.30 GHz vs 4.60 GHz), more L3 cache (30 MB vs 18 MB), and 20 PCIe Gen 5 lanes versus 4. These specifications, combined with its 90th percentile ranking and average benchmark score of 47697, indicate it is a high-performance desktop part designed for multi-threaded and single-threaded workloads. Its nearest rivals, the AMD Ryzen 9 PRO 5945, AMD Ryzen 9 7900X3D, AMD Ryzen 9 3900, and Intel Core Ultra X9 378H, all sit within 0.5% of its average score, confirming it competes at the top of the desktop mainstream.

The Intel Arc G3 is a mobile part with a much lower TDP of 25 W, which suits thinner, battery-conscious systems. It offers higher memory bandwidth (136.5 GB/s vs 102.4 GB/s) and a smaller physical footprint via the Intel BGA 2540 socket. Its 14 cores and 14 threads are sufficient for general mobile productivity, and its 4.60 GHz boost clock handles responsive single-threaded tasks. The lack of any benchmark scores for the Arc G3 means its performance cannot be quantified against the Ultra 7 265T, but its 50th percentile ranking places it in the middle of the database, far below the Ultra 7 265T's 90th percentile.

For a desktop build requiring maximum core count, cache, and PCIe expansion, the Intel Core Ultra 7 265T is the choice based on its specifications and measured benchmarks. For a mobile system where power draw and memory bandwidth matter more than raw core count, the Intel Arc G3 is the appropriate option. The Ultra 7 265T's launch MSRP is $384. The two processors target different market segments, and the data does not suggest either is a substitute for the other.
