Intel Core 5 221E vs Intel Core Ultra 9 386H Comparison

The Intel Core 5 221E and the Intel Core Ultra 9 386H represent two distinct approaches to processing, one anchored in the desktop space and the other in high-end mobile. The recorded data shows a split personality in their performance, with each delivering decisive wins in different categories. The Core 5 221E, built on Bartlett Lake, takes the lead in raw single-core Cinebench scores and integer math, while the Core Ultra 9 386H, a Panther Lake mobile part, dominates multi-core rendering and a broad suite of Passmark workloads. This divergence is not a simple one-sided affair; it is a reflection of different architectures, power envelopes, and target markets. The benchmark results indicate that the choice between these two is less about a clear winner and more about matching the silicon to the workload.

Where Each One Wins

The division of wins is stark. The database records 13 benchmark victories for the Intel Core Ultra 9 386H against only 4 for the Intel Core 5 221E. The Core Ultra 9’s wins are concentrated in multi-threaded and throughput-heavy tests. It takes the top spot in Cinebench R15 multi-core, R20 multi-core, and nearly every Passmark category, including data compression, data encryption, extended instructions, prime number finding, floating point math, multithread, physics, random string sorting, and single-thread. This indicates a processor tuned for sustained parallel workloads, which aligns with its mobile high-performance positioning.

The Intel Core 5 221E, conversely, secures its wins in a more selective set of scenarios. It wins Cinebench R15 single-core, Cinebench R23 multi-core, Cinebench R23 single-core, and Passmark integer math. The R23 multi-core win is particularly notable, as it suggests that in certain rendering workloads, the desktop part with its higher sustained power capacity can outpace the mobile chip despite the latter’s architectural advantages. The integer math win points to a strength in specific arithmetic operations that may benefit certain scientific or financial applications. The data does not show a universal superiority for either chip; it shows a strategic division of strengths.

Architecture Differences

The two processors diverge fundamentally in their underlying designs. The Intel Core 5 221E uses the Bartlett Lake architecture on a 10 nm process node, manufactured by Intel. It is a desktop part for the Intel Socket 1700, with a thermal design power of 65 watts. The chip packs 14 cores and 20 threads, indicating the use of hyper-threading. Its cache hierarchy is defined by 80 KB of L1 per core, 2 MB of L2 per core, and a shared 24 MB of L3 cache. The die size is measured at 257 mm². This is a conventional layout designed for a desktop environment where power draw is less constrained.

The Intel Core Ultra 9 386H is a different beast entirely. It is built on the Panther Lake architecture, using a 3 nm process node from Intel. It is a mobile processor for the Intel BGA 2540 socket, with a significantly lower thermal design power of 25 watts. Despite the lower TDP, it features 16 cores, though only 16 threads, which means it does not use hyper-threading. Its cache configuration is larger in some respects, with 192 KB of L1 per core and 2.5 MB of L2 per core, but its shared L3 cache is smaller at 18 MB. The smaller process node and lower power envelope indicate a design focused on efficiency within a constrained thermal budget.

Memory support further differentiates the pair. The Core 5 221E supports both DDR4 and DDR5 memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. It also supports ECC memory, a feature absent from the Core Ultra 9 386H. The mobile chip supports DDR5 and LPDDR5X, also on a dual-channel bus, but offers a higher memory bandwidth of 115.2 GB/s. PCIe connectivity also differs, with the desktop part offering Gen 5 with 16 lanes, while the mobile part offers Gen 5 with 12 lanes. The integrated graphics differ as well: the Core 5 221E uses UHD Graphics 730, while the Core Ultra 9 386H includes Intel Xe3 Graphics.

Head-to-Head Benchmarks

The benchmark comparison reveals a pattern of extreme swings. The largest win for the Core 5 221E comes in Cinebench R23 single-core, where it scores 3661 against the Core Ultra 9’s 2071.5, a delta of 76.7% in favor of the desktop chip. This is a massive gap that shows the Core 5 221E at its best in lightly threaded tasks that rely on high clock speeds. Its boost clock of 5.20 GHz, compared to the mobile chip’s 4.90 GHz, likely contributes to this outcome.

The Core Ultra 9 386H counters with a substantial win in the prime number finding test, recording a score of 341 against the Core 5 221E’s 173, a delta of 49.3%. This indicates a strong performance in integer-heavy computational loops. The mobile chip also shows a 37.5% advantage in extended instructions, scoring 29138 to the desktop chip’s 18216. In floating point math, the Core Ultra 9 leads with 108527 against 79028, a 27.2% difference. The data encryption test shows a 29.3% advantage for the mobile part, with scores of 27150 and 19205 respectively.

The multi-core Cinebench results are more complex. In Cinebench R15 multi-core, the Core Ultra 9 wins with 3223 against 2613, a delta of 18.9%. In Cinebench R20 multi-core, the mobile chip wins again with 12820 against 10891, a 15% difference. However, in Cinebench R23 multi-core, the tables turn. The Core 5 221E scores 25933 against the Core Ultra 9’s 20547, a 26.2% win for the desktop part. This inconsistency across versions of Cinebench suggests that the workload characteristics changed, favoring the desktop chip’s higher power draw in the newer test.

The single-thread Passmark score is nearly a tie. The Core Ultra 9 wins with 4218 against 4147, a delta of only 1.7%. The multithread Passmark test shows a more decisive result, with the Core Ultra 9 scoring 35399 against 30510, a 13.8% lead. The physics test also goes to the mobile chip, with 3028 against 2230, a 26.4% difference. Integer math is the other win for the Core 5 221E, with a score of 117813 against 87284, a 35% advantage for the desktop part.

The Verdict

The data presents a clear picture of two processors serving different purposes. The Intel Core 5 221E is the stronger choice for users who prioritize high single-core performance in legacy and specific modern benchmarks, as well as integer math operations. Its Cinebench R23 single-core lead of 76.7% is decisive, and its integer math win of 35% indicates a niche strength. Its higher TDP of 65 watts, compared to the Core Ultra 9’s 25 watts, suggests it is designed for a desktop environment where sustained power delivery is not a limiting factor.

The Intel Core Ultra 9 386H is the better performer for mixed and multi-threaded workloads. It wins the majority of the head-to-head tests, including all the Passmark throughput categories except integer math. Its wins in data compression, encryption, extended instructions, and floating point math show a broad capability. Its lower TDP of 25 watts makes it suitable for mobile platforms, and its higher memory bandwidth of 115.2 GB/s supports data-intensive tasks. The average benchmark score confirms this: the Core Ultra 9 has an average score of 43210 against the Core 5 221E’s 40144. The percentileVsAllCpus data also favors the mobile chip, with 88 against 87.

The choice depends on the target platform. For a desktop system where single-core speed and integer performance are paramount, the Core 5 221E is the logical selection. For a mobile system requiring broad multi-core capability and efficiency, the Core Ultra 9 386H is the better fit. The data does not support a single universal winner.
