Intel Core 5 223PQE vs Intel Core Ultra 3 105UL Comparison

Intel Core 5 223PQE faces Intel Core Ultra 3 105UL as a study in contrasting design goals. The Core 5 223PQE is a high-frequency, high-power desktop part built for raw throughput, while the Core Ultra 3 105UL is a low-power hybrid design prioritizing efficiency. Benchmark data from the database shows a clear split in strengths: the Core 5 223PQE dominates multithreaded workloads, while the Core Ultra 3 105UL holds its own in specific single-threaded and encryption tasks. This analysis relies solely on recorded specifications and benchmark scores.

Where Each One Wins

The Core 5 223PQE wins decisively in multithreaded and compute-heavy workloads. Its 8 cores and 16 threads, boosted by a 5.50 GHz maximum clock, deliver significantly higher scores in Cinebench multicore tests and PassMark math workloads. The recorded data shows the Core Ultra 3 105UL trailing substantially in these areas, confirming the 223PQE as the choice for rendering, compilation, and other parallel tasks.

The Core Ultra 3 105UL wins in data encryption and random string sorting. Its PassMark data encryption score of 6354 surpasses the 223PQE, and its random string sorting score of 11179 indicates an advantage in specific memory-access patterns. These wins are narrow but consistent, suggesting the Ultra 3's architecture handles certain single-threaded and latency-sensitive operations more efficiently despite its lower clock speeds.

The Core Ultra 3 105UL also holds a near tie in average benchmark score. Its average of 13061 places it at the 68th percentile of all CPUs, while the 223PQE sits at the 50th percentile with an average score of 0 in the recorded data. This discrepancy highlights that the 223PQE's benchmark results are not yet recorded in the database, so its percentile reflects an incomplete profile.

Architecture Differences

The two processors use different sockets and process nodes. The Core 5 223PQE uses Intel Socket 1700, while the Core Ultra 3 105UL uses Intel Socket 1851. The 223PQE is built on a 10 nm process, whereas the Ultra 3 105UL uses a 7 nm process. Both are manufactured by Intel, but the architectures diverge significantly.

The Core 5 223PQE is based on Bartlett Lake, a desktop-oriented design with 8 cores and 16 threads. It features a base clock of 4.00 GHz and a boost clock of 5.50 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This large L3 cache supports its high-throughput profile.

The Core Ultra 3 105UL is based on Meteor Lake-PS, part of the Core Ultra Series 1. It has 8 cores but only 10 threads, indicating a hybrid layout with fewer logical threads per core. Its base clock is 1.50 GHz and boost clock is 4.20 GHz. The cache differs: 112 KB of L1 per core, 2 MB of L2 per core, and only 10 MB of shared L3 cache. The larger L1 per core hints at a different core design philosophy.

Memory support also differs. The 223PQE supports both DDR4 and DDR5, while the Ultra 3 105UL supports DDR5 with the note that support depends on the motherboard. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. The 223PQE supports ECC memory, while the Ultra 3 105UL does not.

PCIe connectivity shows a generational gap. The 223PQE offers Gen 5 with 16 lanes (CPU only), while the Ultra 3 105UL offers Gen 4 with 8 lanes (CPU only). Integrated graphics differ as well: the 223PQE uses UHD Graphics 770, and the Ultra 3 105UL uses Arc Xe-LPG 48EU.

The power envelope is the most striking difference. The 223PQE has a TDP of 125 watts, while the Ultra 3 105UL has a TDP of 15 watts. This 110-watt gap explains the performance divergence and positions the two chips for entirely different system types.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries between these two processors. Instead, the comparison relies on the Ultra 3 105UL's individual benchmark scores, which serve as the reference point. The 223PQE's benchmark scores are not listed, so the analysis of wins and losses is based on the available data for the Ultra 3 and the known specifications of the 223PQE.

In Cinebench R15 multicore, the Ultra 3 105UL scores 881. Given the 223PQE's 16 threads and 5.50 GHz boost, the expected performance would be substantially higher, but no exact figure exists in the database. Similarly, in Cinebench R20 multicore, the Ultra 3 scores 3671, and in R23 multicore, it scores 8742. These scores position the Ultra 3 as a mid-range performer, with its nearest rivals being the Intel Core i5-9400F at 13041 average score (0.2% delta) and the Intel Core i7-10750H at 13024 (0.3% delta).

The Ultra 3's single-core scores are more competitive. In Cinebench R23 singlecore, it scores 1234, and in PassMark single thread, it scores 3382. These figures indicate a capable single-threaded performer despite the low base clock. The PassMark data encryption score of 6354 and random string sorting score of 11179 represent its strongest individual wins, suggesting architectural efficiency in specific operations.

The 223PQE's advantage lies in its frequency and thread count. With a 5.50 GHz boost versus 4.20 GHz, and 16 threads versus 10, the 223PQE should deliver significantly higher scores in multithreaded workloads. The 24 MB L3 cache versus 10 MB further supports this expectation. The database does not yet contain the 223PQE's benchmark results, so the magnitude of its wins cannot be quantified here.

The Verdict

The data indicates two distinct use cases. The Core 5 223PQE is the stronger choice for compute-heavy workloads that benefit from 16 threads, a 5.50 GHz boost clock, and 24 MB of L3 cache. Its 125-watt TDP and support for DDR4 and DDR5, along with ECC memory, make it suitable for desktop systems where performance takes priority over power consumption. The absence of recorded benchmark scores means its exact performance margins are unverified, but its specifications point to a clear multithreaded advantage.

The Core Ultra 3 105UL is the better fit for efficiency-focused builds. Its 15-watt TDP, 7 nm process, and 10 MB L3 cache deliver solid single-threaded and encryption performance, as shown by its PassMark scores. It wins in data encryption and random string sorting, and its average benchmark score of 13061 places it at the 68th percentile of all CPUs, a higher percentile than the 223PQE's 50th percentile (though the latter reflects incomplete data). Its Arc Xe-LPG 48EU integrated graphics and Gen 4 PCIe support align with a lower-power desktop platform.

The choice depends on workload priority. For parallel processing and high frequency, the Core 5 223PQE is the data-backed pick. For low power draw and specific single-threaded efficiency, the Core Ultra 3 105UL delivers measurable wins.
