Intel Core 5 221TE vs Intel Core i5-1334U Comparison

Head-to-Head Benchmarks

The benchmark results paint a clear picture of two very different processors. The Intel Core i5-1334U wins 10 of the 17 head-to-head tests, while the Intel Core 5 221TE takes 7. The margins, however, tell a more complex story than the raw win count.

The most dramatic victory belongs to the Core i5-1334U in single-threaded PassMark testing. It scores 3345 against the Core 5 221TE's 1734, a massive 92.9% advantage. This is a colossal gap in everyday responsiveness. The same pattern appears in Cinebench R15 single-core, where the mobile chip scores 241 versus the desktop chip's 160, a 50.6% lead. The Core i5-1334U also dominates in the older Cinebench R15 multi-core test, scoring 1569 against the 221TE's 1139, a 37.8% victory.

The data shows the Core i5-1334U also wins the math-heavy PassMark integer workload decisively, scoring 50374 versus 42303, a 19.1% advantage. It further edges out the competition in floating-point math, winning 34474 to 31661, an 8.9% margin. Data encryption also goes to the mobile part, 9377 versus 8963, a 4.6% gain.

The Core 5 221TE, however, fights back hard in newer Cinebench tests. In Cinebench R23 multi-core, it posts a commanding 11305 against 8641, a 23.6% lead. This is its strongest multi-threaded statement. It also wins in Cinebench R20 multi-core, though narrowly, with a score of 4748 versus 4638, a 2.3% margin. The single-core R20 test goes to the 221TE as well, 670 against 654, a 2.4% edge.

The desktop chip's PassMark results are equally telling. It dominates prime number finding, scoring 59 to the i5-1334U's 39, a 33.9% lead. It also wins physics simulation, 1026 to 722, a 26.1% margin. Extended instruction sets go to the 221TE, 9655 versus 8563, an 11.3% win. Data compression is also its territory, 156682 against 150568, a 3.9% difference.

Where Each One Wins

The use-case split follows the benchmark deltas closely. The Core i5-1334U is the clear winner for single-threaded tasks and light, responsive workloads. Its 92.9% lead in PassMark single-thread and 50.6% lead in Cinebench R15 single-core show it is far better at tasks that depend on one or two fast cores. The 19.1% integer math advantage also makes it the better choice for general computing, spreadsheets, and code compilation that is not fully parallelized.

The Core 5 221TE takes the crown for heavily multi-threaded workloads. Its 23.6% lead in Cinebench R23 multi-core is the most decisive multi-threaded result. The 33.9% advantage in prime number calculation and the 26.1% physics score also point toward its strength in rendering, simulation, and other tasks that scale with core count and threads. The 11.3% win in extended instructions suggests it is more efficient at advanced computational workloads.

The data also shows a near tie in random string sorting, with the i5-1334U winning by a fraction of a point (16933 to 16929, effectively zero). This is a rare case where the two chips are mathematically identical.

Architecture Differences

The two processors come from different Intel design lines. The Core i5-1334U uses the Raptor Lake architecture, specifically the Raptor Lake-U mobile variant. The Core 5 221TE uses the Bartlett Lake architecture, a desktop part. The process node is identical at 10 nm, with Intel as the foundry for both.

Core counts are the same at 10 cores each. The thread count, however, differs. The i5-1334U has 12 threads, while the 221TE has 16 threads. The 221TE's four extra threads explain its stronger multi-threaded scores in newer tests. Both share the same L1 cache size of 80 KB per core and the L2 cache of 1.25 MB per core. The L3 cache, however, is twice as large on the desktop chip: 24 MB shared on the 221TE versus 12 MB shared on the i5-1334U.

The Core 5 221TE also features a larger physical die size of 215 mm². The i5-1334U has no recorded die size in the database. Memory support is identical for both, DDR4 and DDR5, running dual-channel. The 221TE has a rated memory bandwidth of 76.8 GB/s, while the i5-1334U has no recorded bandwidth figure. A key architectural difference is ECC memory support, which the 221TE offers and the i5-1334U lacks.

The integrated graphics differ as well. The i5-1334U uses Iris Xe Graphics with 80 execution units, while the 221TE uses the more basic UHD Graphics 730. The sockets are also different, with the mobile chip on Intel BGA 1744 and the desktop chip on Intel Socket 1700. PCIe connectivity favors the desktop part: it has Gen 5 with 16 lanes (CPU only), while the mobile part has Gen 4 with 8 lanes.

The Verdict

The data supports two distinct user profiles. The Core i5-1334U is the choice for anyone needing maximum single-threaded performance and energy efficiency in a mobile form factor. Its 92.9% lead in PassMark single-threaded and 50.6% lead in Cinebench R15 single-core are definitive. Its 15 W TDP makes it suitable for thin-and-light laptops, and it wins the majority of tests in this comparison, including integer math, floating point, and encryption.

The Core 5 221TE is the pick for desktop users who prioritize multi-threaded throughput and do not care about power draw. Its 23.6% lead in Cinebench R23 multi-core, 33.9% lead in prime number calculation, and 26.1% lead in physics show it is the stronger choice for rendering, simulation, and other parallel workloads. Its 76.8 GB/s memory bandwidth and ECC support make it a more robust platform for professional or server-like duties.

The data does not suggest a universal winner. It suggests a split: the i5-1334U for single-threaded and mobile workloads, the 221TE for multi-threaded desktop tasks. The 221TE also has a lower launch MSRP of $232, while the i5-1334U launched at $340. The benchmark scores (an average of 17860 for the 221TE and 18154 for the i5-1334U) are close, but the distribution of wins is not. Choose based on the workload, not the average.
