Intel Core 5 223PTE vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The recorded data does not include a direct head-to-head benchmark run between the Intel Core 5 223PTE and the Intel Core Ultra 5 245T. The head-to-head benchmark array is empty, and the win counters for both processors are zero. This means the database lacks matched-pair test results where both CPUs ran the identical workload under the same conditions. What is available instead is a full benchmark suite for the Core Ultra 5 245T and no benchmark entries for the Core 5 223PTE. The Core Ultra 5 245T shows an average benchmark score of 38194, which places it in the 86th percentile of all CPUs in the database. The Core 5 223PTE has an average benchmark score of zero and sits at the 50th percentile, but that zero reflects missing measurements rather than a true performance result.

The Core Ultra 5 245T's recorded scores cover multiple rendering and compute workloads. In Cinebench R23, it scores 26208 in multi-core and 3699 in single-core. In Cinebench R20, the scores are 11007 multi-core and 1553 single-core. The older Cinebench R15 run shows 2641 multi-core and 372 single-core. These are the only CPU rendering numbers in the pack, and they come exclusively from the Ultra 5 245T. There are no corresponding Cinebench scores for the Core 5 223PTE, so a direct percentage comparison between the two cannot be derived from the data.

PassMark results for the Ultra 5 245T provide additional detail. Integer math scores 88676, floating point math scores 108499, and extended instructions score 22071. Data compression scores 283812, while data encryption scores 23656. Random string sorting scores 34931, and finding prime numbers scores 324. The multithread score is 30833, and the single-thread score is 4367. Physics testing scores 2278. None of these workloads appear in the Core 5 223PTE entry, so the database offers no numerical basis for claiming either processor outperforms the other in any specific test.

The absence of head-to-head results limits the analysis to architectural and specification-level comparison. The nearest rivals for the Ultra 5 245T give some context for its standing. AMD Ryzen 7 250 scores 38221, which is 0.1% above the Ultra 5 245T. Intel Core i5-13600HX scores 38261, 0.2% above. Intel Core i5-14490F scores 38149, 0.1% below. Intel Core i5-13600KF scores 38103, 0.2% below. These deltas are tiny, placing the Ultra 5 245T in a tight performance cluster. The Core 5 223PTE has no nearest rivals listed, so no such positioning exists for it.

Architecture Differences

The two processors come from different architectural lineages. The Core 5 223PTE uses the Bartlett Lake codename and belongs to the Core 5 (Bartlett Lake) generation. It is built on a 10 nm process node at Intel's foundry. The Core Ultra 5 245T uses the Arrow Lake architecture, specifically Arrow Lake-S, and belongs to the Core Ultra Series 2 generation. It is built on a 3 nm process node at TSMC. The process node difference is substantial: 10 nm versus 3 nm, and the foundry shifts from Intel to TSMC. The Ultra 5 245T also has a transistor count of 17,800 million and a die size of 243 mm², while the Core 5 223PTE lists no transistor count and no die size in the database.

Core counts differ sharply. The Core 5 223PTE has 8 cores and 16 threads. The Core Ultra 5 245T has 14 cores and 14 threads. That means the Core 5 223PTE uses simultaneous multithreading to reach 16 threads from 8 physical cores, while the Core Ultra 5 245T runs one thread per core with no multithreading. The Ultra 5 245T has more physical cores but fewer total threads. Cache layouts also differ. The Core 5 223PTE has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 5 245T has 192 KB of L1 per core, 3 MB of L2 per core, and the same 24 MB of shared L3. The Ultra 5 245T carries more private cache per core in both L1 and L2, while total L3 is identical.

Clock speeds move in opposite directions. The Core 5 223PTE has a base clock of 2.30 GHz and a boost clock of 5.40 GHz. The Core Ultra 5 245T has a base clock of 2.20 GHz and a boost clock of 5.10 GHz. The Core 5 223PTE starts slightly higher at base and boosts 0.30 GHz higher. Thermal design power is higher for the Ultra 5 245T at 65 watts, while the Core 5 223PTE sits at 45 watts. The sockets are incompatible: the Core 5 223PTE uses Intel Socket 1700, and the Core Ultra 5 245T uses Intel Socket 1851. Memory support diverges as well. The Core 5 223PTE supports DDR4 and DDR5, while the Core Ultra 5 245T supports DDR5 only. Both run dual-channel memory, but memory bandwidth differs: 89.6 GB/s for the Core 5 223PTE versus 102.4 GB/s for the Core Ultra 5 245T. Both support ECC memory.

PCIe lanes differ in count. The Core 5 223PTE provides Gen 5 with 16 lanes (CPU only). The Core Ultra 5 245T provides Gen 5 with 20 lanes (CPU only). Integrated graphics also differ. The Core 5 223PTE uses UHD Graphics 770, while the Core Ultra 5 245T uses Arc Xe-LPG Graphics 64EU. Release dates are not the same: the Core 5 223PTE released in March 2026, and the Core Ultra 5 245T released in January 2025. Both are listed as Active in production status, and neither has an unlocked multiplier.

Where Each One Wins

Without head-to-head benchmark data, wins must be inferred from specifications. The Core 5 223PTE holds advantages in boost clock, base clock, and power envelope. Its 5.40 GHz boost clock exceeds the Ultra 5 245T's 5.10 GHz, and its 2.30 GHz base clock is slightly above 2.20 GHz. The 45 watt TDP is lower than the Ultra 5 245T's 65 watts, which suggests less heat output and lower power draw under sustained loads. The Core 5 223PTE also supports DDR4 memory, which is relevant for systems that reuse older memory modules. Its Socket 1700 compatibility may matter in platforms that already use that socket.

The Core Ultra 5 245T counters with more physical cores, 14 versus 8, and a smaller process node at 3 nm versus 10 nm. The larger per-core cache hierarchy, 192 KB L1 and 3 MB L2, could benefit workloads with high data reuse. Memory bandwidth is higher at 102.4 GB/s versus 89.6 GB/s, and the PCIe lane count is higher at 20 versus 16. The integrated graphics solution is newer, Arc Xe-LPG Graphics 64EU, compared to UHD Graphics 770. The transistor count of 17,800 million, produced at TSMC, points to a denser, more modern implementation.

The benchmark data, though one-sided, shows the Ultra 5 245T delivers strong multi-threaded and single-threaded results in Cinebench and PassMark tests. Its 26208 Cinebench R23 multi-core score and 4367 PassMark single-thread score demonstrate capability across both parallel and latency-sensitive workloads. But since the Core 5 223PTE has no recorded benchmarks, the database does not show whether it wins in any measured workload. The wins for the Core 5 223PTE are purely specification-based: higher clocks, lower TDP, DDR4 support. The wins for the Ultra 5 245T are specification-based as well, plus it has actual measured benchmark scores.

The Verdict

The database supports a clear distinction, but not a direct performance comparison. The Intel Core Ultra 5 245T is the only one of the two with recorded benchmark results. Its average score of 38194 and 86th percentile ranking place it among strong performers, with nearest rivals within 0.2% in either direction. The Intel Core 5 223PTE has no benchmarks, so any claim that it outperforms the Ultra 5 245T in a specific workload cannot be supported by the data.

For users prioritizing measured performance, the Core Ultra 5 245T is the only option with evidence. It delivers 14 physical cores, a 3 nm TSMC process, 17,800 million transistors, higher memory bandwidth at 102.4 GB/s, more PCIe lanes at 20, and a newer integrated graphics unit. It also has a higher TDP of 65 watts, which reflects the larger core count and power budget.

For users prioritizing clock speed, power efficiency, and memory flexibility, the Core 5 223PTE offers a higher boost clock of 5.40 GHz, a lower TDP of 45 watts, and support for DDR4 alongside DDR5. Its 8 cores and 16 threads provide multithreading, and its Socket 1700 compatibility targets a different platform generation. The launch MSRP for the Core 5 223PTE is $232, while the launch MSRP for the Core Ultra 5 245T is $270.

The choice depends on whether the workload benefits from more physical cores and a modern process node, or from higher clocks, lower power, and DDR4 support. The benchmark data favors the Core Ultra 5 245T, but the Core 5 223PTE's specifications define a distinct profile for lower-power systems. The data does not answer which is faster in a given application because no matched tests exist. It only shows which processor has recorded performance evidence, and that is the Core Ultra 5 245T.
