Intel Core 5 221TE vs Intel Core Ultra 7 265H Comparison

The Intel Core 5 221TE and Intel Core Ultra 7 265H represent two distinct Intel design philosophies: a desktop-focused Bartlett Lake chip versus a mobile Arrow Lake-H processor. The recorded benchmark data shows a decisive performance gap, with the Ultra 7 265H winning all 17 head-to-head comparisons. This analysis breaks down the scale of that difference, the architectural reasons behind it, and the specific workloads where each processor retains relevance.

Head-to-Head Benchmarks

The benchmark results are unambiguous. The Intel Core Ultra 7 265H wins every single recorded test, with margins ranging from 23.3% to 82.4%. The largest gap appears in the PassMark find prime numbers test, where the Ultra 7 scores 335 against the Core 5's 59, a delta of -82.4%. This indicates a massive advantage in integer-heavy, single-threaded calculation loops.

In multi-core rendering, the Ultra 7's dominance is consistent. Cinebench R23 multi-core shows the Ultra 7 at 19940 versus 11305 for the Core 5, a 43.3% lead. The gap widens in Cinebench R20 multi-core, where the scores are 12131 and 4748 respectively, a 60.9% difference. Cinebench R15 multi-core follows the same pattern, with 2989 against 1139, also a 61.9% delta. The data indicates that the Ultra 7 delivers roughly double the multi-threaded throughput in several tests.

Single-core performance also favors the Ultra 7, though by a smaller margin. Cinebench R23 single-core shows 2080 versus 1596, a 23.3% lead. Cinebench R20 single-core records 1712 against 670, a 60.9% difference, while Cinebench R15 single-core shows 307 versus 160, a 47.9% gap. The smaller R23 delta suggests that the architectural improvements in the Ultra 7 are more pronounced in sustained multi-core workloads than in short single-threaded bursts, although the single-core advantage remains substantial.

PassMark results reinforce the pattern. The Ultra 7 leads in data compression (334711 vs 156682, -53.2%), data encryption (26005 vs 8963, -65.5%), extended instructions (26805 vs 9655, -64%), floating point math (109123 vs 31661, -71%), integer math (85479 vs 42303, -50.5%), multithread (34027 vs 13301, -60.9%), physics (2497 vs 977, -60.9%), and random string sorting (40742 vs 16929, -58.4%). The single-thread PassMark score shows 4334 for the Ultra 7 against 1734 for the Core 5, a 60% lead.

The average benchmark score places the Ultra 7 at 41621, while the Core 5 averages 17860. This translates to a percentile rank of 88 for the Ultra 7 versus 71 for the Core 5 among all CPUs in the database. The Core 5's nearest rivals, the AMD Ryzen 5 3600XT and Intel Core 5 120U, sit within 0.2% of its average score, while the Ultra 7's closest competitor, the Intel Core 7 251TE, is only 0.1% ahead. The Core 5 also trails the AMD Ryzen 5 1600 by 0.7%, showing it clusters around older mid-range parts.

Architecture Differences

The two processors are built on fundamentally different platforms. The Core 5 221TE uses the Bartlett Lake architecture on a 10 nm Intel process node, while the Core Ultra 7 265H uses the Arrow Lake architecture on a 3 nm TSMC node. This process advantage is a key factor in the Ultra 7's efficiency and performance ceiling.

The core configurations differ sharply. The Core 5 has 10 cores and 16 threads, while the Ultra 7 has 16 cores and 16 threads. The thread count parity, despite six fewer cores, indicates that the Core 5 relies on Hyper-Threading, whereas the Ultra 7 uses a purely physical core layout. The Ultra 7's base clock is 2.20 GHz and boost clock is 5.30 GHz, versus 1.80 GHz base and 5.00 GHz boost for the Core 5. The higher base clock on the Ultra 7 contributes to its superior sustained performance in all measured tests.

Cache hierarchies also favor the Ultra 7. The Core 5 provides 80 KB of L1 per core and 1.25 MB of L2 per core, while the Ultra 7 offers 192 KB of L1 and 3 MB of L2 per core. Both share 24 MB of L3, but the larger per-core caches on the Ultra 7 reduce memory latency and improve data locality. The Core 5 has a die size of 215 mm²; the Ultra 7's die size is not recorded in the database.

Memory support diverges as well. The Core 5 supports DDR4 and DDR5 with dual-channel memory and a bandwidth of 76.8 GB/s. The Ultra 7 supports DDR5 and LPDDR5X, also dual-channel, but with a higher bandwidth of 102.4 GB/s. Both support ECC memory. The Ultra 7's faster memory bandwidth aligns with its higher throughput in memory-intensive PassMark tests like data compression and random string sorting.

PCIe connectivity differs, with the Core 5 offering Gen 5 with 16 lanes (CPU only) versus the Ultra 7's Gen 5 with 8 lanes (CPU only). The Core 5's desktop socket, Intel Socket 1700, allows for more expansion lanes, while the Ultra 7 uses Intel BGA 2049, a mobile socket. Integrated graphics also differ: the Core 5 uses UHD Graphics 730, while the Ultra 7 uses Arc Graphics 140T, a more capable integrated GPU.

The TDP figures show a notable inversion. The Core 5 has a TDP of 45 W, while the Ultra 7 has a TDP of 28 W. The Ultra 7 delivers significantly higher performance while consuming less power per the recorded TDP, reflecting the efficiency of the 3 nm process and the Arrow Lake architecture. Both processors were released on the same date, January 12, 2025, and both are currently marked as Active in production. The Core 5 has a launch MSRP of $232; the Ultra 7 has no recorded launch MSRP.

Where Each One Wins

The Intel Core Ultra 7 265H wins across every benchmark category in the database. Its strengths are most pronounced in integer-heavy and cryptographic workloads. The find prime numbers test shows an 82.4% lead, and data encryption shows a 65.5% lead. These results indicate the Ultra 7 is markedly better for tasks involving large prime calculations, encryption, and hashing.

Floating-point performance also strongly favors the Ultra 7. The floating point math score of 109123 versus 31661 is a 71% advantage. This suggests the Ultra 7 handles scientific computations, simulations, and graphics-related math far more effectively. The physics score of 2497 versus 977, a 60.9% lead, aligns with this, indicating better performance in physics simulation workloads common in 3D rendering and gaming.

Multi-threaded productivity is another clear win for the Ultra 7. Cinebench R23 multi-core, R20 multi-core, and R15 multi-core all show leads between 43.3% and 61.9%. The PassMark multithread score of 34027 versus 13301, a 60.9% gap, confirms that the Ultra 7 is the better choice for video encoding, 3D rendering, and other parallel workloads.

The Intel Core 5 221TE does not win any benchmark in the recorded data. Its only potential advantages lie outside the measured performance. It offers a desktop socket with 16 PCIe Gen 5 lanes, double the Ultra 7's 8 lanes, which is relevant for systems with multiple high-bandwidth expansion cards. The Core 5 also supports DDR4 memory, which may be a practical compatibility consideration for existing desktop platforms, though the database shows no benchmark where this translates to a performance win.

The Verdict

The data indicates that the Intel Core Ultra 7 265H is the superior processor in every measured dimension. With an average benchmark score of 41621 against 17860, the Ultra 7 outperforms the Core 5 by a factor of roughly 2.3. Its percentile rank of 88 versus 71 places it in a higher performance tier overall. The Ultra 7 achieves this while maintaining a lower TDP of 28 W versus 45 W, making it the more efficient choice for both mobile and compact desktop systems.

The Core 5 221TE cannot be recommended based on performance data alone. It loses all 17 head-to-head comparisons, with the smallest deficit being 23.3% in Cinebench R23 single-core. Its nearest rivals in the database, such as the AMD Ryzen 5 3600XT and Intel Core 5 120U, are within 0.2% of its average score, indicating it competes with older mid-range parts rather than modern high-end chips.

For users prioritizing raw compute performance, the Core Ultra 7 265H is the clear choice. The data shows it delivers higher single-core and multi-core scores, faster memory bandwidth, and better efficiency. The Core 5 221TE may still serve specific desktop builds where the 16 PCIe lanes and DDR4 support are required, but the benchmark results show no performance scenario where it beats the Ultra 7. The verdict from the recorded measurements is unambiguous: the Ultra 7 265H dominates.
