Intel Core 5 221TE vs Intel Core i7-1365U Comparison

Head-to-Head Benchmarks

The benchmark data reveals a fascinating split between these two Intel processors. The Intel Core i7-1365U secures 12 outright wins across the test suite, while the Intel Core 5 221TE takes 5. However, the margins tell a more nuanced story than the raw win count suggests.

The most dramatic gap appears in single-threaded performance. In Cinebench R15 single-core, the i7-1365U scores 265.5 against the 221TE's 160, a staggering 65.9% advantage. PassMark single-thread results amplify this further: 3411 versus 1734, a 96.7% lead for the i7-1365U. This is the single largest delta in the entire comparison, nearly doubling the Core 5's score. The i7's 5.20 GHz boost clock versus the 221TE's 5.00 GHz boost clock in the specification data explains part of this edge, though the architectural differences discussed below play a larger role.

Multi-threaded results are less one-sided. Cinebench R23 multicore actually favors the Core 5 221TE decisively: 11305 versus 8946, a 20.9% victory for the desktop chip. This aligns with its 16 threads against the i7's 12 threads, plus its 24 MB of shared L3 cache versus 12 MB. Yet in Cinebench R15 multicore, the i7-1365U wins by 28.8% (1466.5 versus 1139), and in Cinebench R20 multicore the gap shrinks to just 2.8% (4882 versus 4748). The results vary notably across Cinebench versions, suggesting workload-specific scaling behavior.

PassMark tests split along similar lines. The i7-1365U dominates integer math by 20.3% (50881 versus 42303), floating-point math by 6.4% (33689 versus 31661), and multithread by 5.6% (14045 versus 13301). Data encryption favors the i7 by 6.3% (9531 versus 8963). The Core 5 221TE fights back in extended instructions with a 13.8% win (9655 versus 8321) and in data compression by 4.5% (156682 versus 149585). Physics, prime number finding, and random string sorting are all within 1.7% of each other, statistical noise for practical purposes.

Average benchmark scores place the i7-1365U at 18177 versus the 221TE's 17860, a 1.8% overall edge. Percentile rankings confirm near-parity: 72nd percentile for the i7, 71st for the Core 5. The nearest rivals list reinforces this: the i7-1365U trades blows with the AMD Ryzen 7 5700U (delta 0%), while the Core 5 221TE sits within 0.7% of the AMD Ryzen 5 1600.

Architecture Differences

The two chips come from different Intel design lineages despite sharing the same 10 nm process node. The i7-1365U uses Raptor Lake architecture (Raptor Lake-U codename), a mobile-focused design. The Core 5 221TE uses Bartlett Lake architecture, a desktop-oriented part. Both are built at Intel's own foundry on 10 nm.

Core counts match at 10, but thread counts diverge: the i7-1365U offers 12 threads, while the Core 5 221TE provides 16. This suggests different hybrid core configurations, with the desktop chip likely employing more efficient-core threads. Base clocks are identical at 1.80 GHz, but boost clocks differ slightly: 5.20 GHz for the i7 versus 5.00 GHz for the 221TE.

Cache hierarchies show meaningful divergence. Both have 80 KB L1 per core and 1.25 MB L2 per core. The shared L3 cache, however, doubles from 12 MB on the i7-1365U to 24 MB on the Core 5 221TE. This larger pool of last-level cache likely contributes to the 221TE's superior Cinebench R23 multicore score and its wins in data compression and extended instructions.

The die size differs as well: the Core 5 221TE measures 215 mm², while the i7-1365U's die size is not recorded in the database. This reflects the desktop chip's larger physical footprint and higher power envelope. Thermal design power tells the story: the i7-1365U is rated at 15 W, a true ultra-low-power mobile part, while the Core 5 221TE draws 45 W, a mainstream desktop-class power budget.

Memory support is similar on paper: both accept DDR4 and DDR5 across dual-channel buses. The Core 5 221TE has a recorded memory bandwidth of 76.8 GB/s, while the i7-1365U's bandwidth is unlisted. ECC memory support splits them clearly: the Core 5 221TE supports ECC, the i7-1365U does not. This makes the desktop chip more suitable for error-sensitive workloads.

PCIe connectivity differs substantially. The i7-1365U provides Gen 4 with 8 lanes (CPU only), while the Core 5 221TE offers Gen 5 with 16 lanes (CPU only). The newer, wider PCIe implementation on the desktop part enables faster peripheral and GPU connectivity.

Integrated graphics also diverge. The i7-1365U carries Iris Xe Graphics with 96 execution units, a capable mobile iGPU. The Core 5 221TE instead uses UHD Graphics 730, a more basic desktop graphics solution. For CPU-only comparisons these differences matter less, but for systems relying on integrated display output, the i7's Iris Xe is the stronger option.

The Verdict

The data points to different buyers for each chip. The Intel Core i7-1365U is the clear choice for single-threaded workloads and mixed productivity tasks. Its 96.7% PassMark single-thread advantage and 18.2% Cinebench R23 single-core lead are decisive. The 20.3% integer math win and 6.4% floating-point math win further cement its position for everyday responsiveness and general-purpose computing. Mobile users benefit from its 15 W TDP and Iris Xe Graphics 96EU, which provides stronger integrated graphics than the UHD Graphics 730 found on the Core 5 221TE.

The Intel Core 5 221TE makes its case in specific multi-threaded scenarios. The 20.9% Cinebench R23 multicore victory indicates strong sustained all-core performance, helped by 16 threads and 24 MB L3 cache. Data compression wins by 4.5% and extended instructions by 13.8% suggest workloads like archiving, scientific computing, and SIMD-heavy code favor the desktop chip. The 45 W TDP, PCIe Gen 5 with 16 lanes, and ECC memory support position it for workstation-class desktop builds where those features matter.

The average scores are nearly identical: 18177 versus 17860. The percentile rankings of 72 and 71 are effectively tied. Neither chip dominates the other comprehensively. The i7-1365U wins more individual tests and has the higher ceiling in single-threaded performance, while the Core 5 221TE counters with superior cache capacity, more threads, and platform features like ECC and Gen 5 PCIe. Users prioritizing snappy single-threaded response and mobile efficiency should select the i7-1365U. Users building a desktop for multi-threaded throughput, ECC reliability, or fast PCIe peripherals should select the Core 5 221TE.
