Intel Core 5 223PTE vs Intel Core Ultra 5 250K Plus Comparison

FAQ

Q: What is the difference in core and thread counts between the Intel Core 5 223PTE and the Intel Core Ultra 5 250K Plus?

A: The Core 5 223PTE has 8 cores and 16 threads, while the Core Ultra 5 250K Plus has 18 cores and 18 threads. This means the Ultra 5 offers more physical cores but no hyper-threading, whereas the Core 5 has fewer cores but each core can handle two threads.

Q: Which processor has the higher boost clock speed?

A: The Intel Core 5 223PTE has a boost clock of 5.40 GHz, which is higher than the Core Ultra 5 250K Plus's boost clock of 5.30 GHz. However, the Ultra 5 has a significantly higher base clock at 4.20 GHz compared to 2.30 GHz for the Core 5.

Q: How do the two processors compare in terms of power consumption?

A: The Core 5 223PTE has a TDP of 45 watts, while the Core Ultra 5 250K Plus has a TDP of 125 watts. This indicates the Ultra 5 draws substantially more power under load.

Q: What kind of memory does each processor support?

A: The Core 5 223PTE supports both DDR4 and DDR5 memory, while the Core Ultra 5 250K Plus supports only DDR5. Both use a dual-channel memory bus, but the Ultra 5 has a higher memory bandwidth at 115.2 GB/s versus 89.6 GB/s for the Core 5.

Q: Which processor has a higher benchmark percentile ranking?

A: The Core Ultra 5 250K Plus ranks in the 93rd percentile among all CPUs, while the Core 5 223PTE ranks in the 50th percentile. The Ultra 5's average benchmark score is 66855, whereas the Core 5 has an average benchmark score of 0 in the database.

Q: Are both processors unlocked for overclocking?

A: No. The Core Ultra 5 250K Plus has an unlocked multiplier, while the Core 5 223PTE does not. The Ultra 5 is therefore designed for overclocking, while the Core 5 is fixed at its factory clocks.

The Verdict

Based on the recorded data, the Intel Core Ultra 5 250K Plus is the stronger performer by a wide margin. Its 93rd percentile ranking versus the Core 5 223PTE's 50th percentile places them in entirely different performance tiers. The Ultra 5 delivers 18 cores, a 3 nm process node from TSMC, and a suite of benchmark scores that consistently show high multi-threaded and single-threaded capability. The Core 5 223PTE, with its 8 cores and 45 watt TDP, is positioned as a lower-power desktop part, but the database shows no benchmark scores for it, meaning its actual performance cannot be quantified here.

Buyers who need maximum throughput for multi-threaded workloads should pick the Core Ultra 5 250K Plus based on its benchmark record and higher core count. Buyers who require lower power consumption and the flexibility of DDR4 memory support might consider the Core 5 223PTE, but they must accept a large performance gap and a lack of recorded benchmark data. The Ultra 5 also has a lower launch MSRP at $199, compared to $232 for the Core 5, which further strengthens its position for those who prioritize performance per dollar.

Head-to-Head Benchmarks

The Core Ultra 5 250K Plus holds benchmark scores across multiple tests, while the Core 5 223PTE has no recorded benchmark entries. In Cinebench R23, the Ultra 5 scores 30867 in multi-core and 2261 in single-core. In Cinebench R20, it scores 18442 multi-core and 2603 single-core. In Cinebench R15, it scores 4640 multi-core and 328 single-core. These numbers show a consistent scaling from older to newer Cinebench versions, with multi-core performance roughly 13.6 times higher than single-core in R23.

PassMark results for the Ultra 5 include a multi-thread score of 51596, a single-thread score of 4757, floating point math at 162692, integer math at 125091, and extended instructions at 44565. Data compression scores 568721, data encryption scores 42144, and random string sorting scores 69090. Physics performance is 3494, and finding prime numbers scores 486.

Since the Core 5 223PTE has no benchmark scores in the database, there are no direct wins for it to report. The only comparisons possible are structural: the Core 5 has a higher boost clock (5.40 GHz vs. 5.30 GHz) and a much lower TDP (45 W vs. 125 W). In every measured workload category, the Ultra 5 outperforms the Core 5 by default because the Core 5 lacks any recorded measurements. The data shows a clear asymmetry: the Ultra 5 is fully characterized, while the Core 5 remains unquantified.

Specification Differences

The two processors differ in nearly every core specification. The Core 5 223PTE has 8 cores and 16 threads, while the Ultra 5 250K Plus has 18 cores and 18 threads. Base clocks are 2.30 GHz for the Core 5 and 4.20 GHz for the Ultra 5. Boost clocks are 5.40 GHz for the Core 5 and 5.30 GHz for the Ultra 5. TDP is 45 W for the Core 5 versus 125 W for the Ultra 5.

Sockets differ as well: the Core 5 uses Intel Socket 1700, while the Ultra 5 uses Intel Socket 1851. Memory support is broader on the Core 5 (DDR4 and DDR5) versus DDR5-only on the Ultra 5. Memory bandwidth is higher on the Ultra 5 at 115.2 GB/s compared to 89.6 GB/s for the Core 5. Both support ECC memory.

PCIe lanes also differ: the Core 5 provides Gen 5 with 16 lanes (CPU only), while the Ultra 5 provides Gen 5 with 20 lanes (CPU only). Integrated graphics are different: the Core 5 uses UHD Graphics 770, while the Ultra 5 uses Arc Xe-LPG Graphics 64EU. The multiplier is locked on the Core 5 and unlocked on the Ultra 5. Release dates are close: the Core 5 launched on 2026-03-08 and the Ultra 5 on 2026-03-10. Launch MSRP is $232 for the Core 5 and $199 for the Ultra 5.

Architecture Differences

The Core 5 223PTE is based on Bartlett Lake, a 10 nm Intel process, while the Core Ultra 5 250K Plus is based on Arrow Lake Refresh, a 3 nm process from TSMC. This is a major architectural divergence: the Ultra 5 uses a more advanced fabrication node, which typically enables higher transistor density and better power efficiency per operation.

The Ultra 5 has a transistor count of 17,800 million and a die size of 243 mm². The Core 5 does not have recorded transistor or die size data. Cache configurations differ substantially. The Core 5 has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The Ultra 5 has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The Ultra 5 thus has more cache at every level.

The Core 5 belongs to the Core 5 (Bartlett Lake) generation, while the Ultra 5 belongs to the Ultra 5 (Arrow Lake) generation and the Core Ultra Series 2. The Ultra 5's codename, Arrow Lake Refresh, suggests a refinement of the earlier Arrow Lake architecture, whereas Bartlett Lake represents a separate desktop line. The foundry difference is also notable: Intel fabricates the Core 5, while TSMC fabricates the Ultra 5.

Integrated graphics differ in architecture as well. The Core 5 uses UHD Graphics 770, while the Ultra 5 uses Arc Xe-LPG Graphics 64EU. The Arc Xe-LPG is a newer GPU architecture compared to the UHD 770, though the database does not provide direct graphics benchmark comparisons.

Where Each One Wins

The Core Ultra 5 250K Plus wins in every category where benchmark data exists. It has more cores (18 vs. 8), a higher base clock (4.20 GHz vs. 2.30 GHz), more L3 cache (30 MB vs. 24 MB), higher memory bandwidth (115.2 GB/s vs. 89.6 GB/s), more PCIe lanes (20 vs. 16), and a smaller process node (3 nm vs. 10 nm). Its benchmark scores confirm strong multi-threaded performance across Cinebench and PassMark tests. The Ultra 5's 93rd percentile ranking places it near the top of the database, with its nearest rival being the AMD EPYC 4465P at a delta of -0.1%, meaning the Ultra 5 is effectively tied with that server chip. It is also 1.1% ahead of the Intel Core Ultra 5 250KF Plus and 0.9% behind the Intel Core Ultra 9 275HX.

The Core 5 223PTE wins in specific structural areas: it has a higher boost clock (5.40 GHz vs. 5.30 GHz), a much lower TDP (45 W vs. 125 W), and broader memory compatibility (DDR4 and DDR5). For workloads that are sensitive to single-thread boost frequency, the Core 5's 5.40 GHz peak could offer a slight advantage, though no benchmark scores confirm this. For power-constrained environments, the 45 W TDP is a clear benefit, allowing for simpler cooling and lower system power draw. The Core 5 also supports DDR4, which may be relevant for systems reusing existing memory modules.

In practical terms, the Ultra 5 is the choice for rendering, encoding, compilation, and any multi-threaded workload where the 18 cores and high cache can be utilized. The Core 5 is better suited for low-power desktop builds or legacy platform upgrades via Socket 1700, where its 45 W TDP and DDR4 support provide flexibility. The data shows no scenario where the Core 5 outperforms the Ultra 5 in measured performance, but its lower power envelope and memory options give it a distinct niche.
