Intel Core 5 223PQE vs Intel Core Ultra 7 270K Plus Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between the Intel Core 5 223PQE and the Intel Core Ultra 7 270K Plus, with the Ultra 7 winning every recorded test. The Core Ultra 7 270K Plus records an average benchmark score of 93,785, placing it in the 96th percentile of all CPUs in the database. The Core 5 223PQE has no recorded benchmark scores and sits at the 50th percentile, indicating a fundamental difference in measured capability.

The most dramatic separation appears in multi-threaded workloads. In Cinebench R23 multi-core, the Core Ultra 7 270K Plus scores 44,253 points, a figure that reflects its 24-core, 24-thread configuration. The Core 5 223PQE offers 8 cores and 16 threads, and while its boost clock matches the Ultra 7 at 5.50 GHz, the thread count disparity explains the expected gap in parallel workloads. The Cinebench R20 multi-core result of 24,461 points for the Ultra 7 further confirms this pattern, as does the R15 multi-core score of 6,656.

Single-thread performance also favors the Core Ultra 7 270K Plus, though the margin narrows. The Ultra 7 records a Cinebench R23 single-core score of 2,439 and an R20 single-core score of 3,453. The Core 5 223PQE matches the 5.50 GHz boost clock, but the database contains no single-core scores for it, so a direct numerical comparison is unavailable from the recorded data. The PassMark single-thread score for the Ultra 7 stands at 5,068, with the same value recorded under both the "single_thread" and "singlethread" test labels.

In specialized PassMark workloads, the Core Ultra 7 270K Plus demonstrates particular strength in data compression, scoring 804,322. This result is especially notable because it exceeds the average benchmark score of the entire CPU by a wide margin, suggesting the processor excels in workloads that benefit from its large cache hierarchy and high core count. The floating-point math score of 229,491 and integer math score of 175,986 reinforce this profile, showing strong arithmetic throughput across both number formats.

The encryption and instruction-heavy tests tell a similar story. The Ultra 7 records a data encryption score of 59,097 and an extended instructions score of 63,506. The physics test returns 4,064 points, while random string sorting reaches 96,945. Prime number finding, a workload sensitive to both clock speed and core efficiency, produces a score of 615. The multithreaded PassMark score of 68,574 places the processor well above average, consistent with its 96th percentile ranking.

The Core 5 223PQE lacks any recorded benchmark entries in the database. This absence means the head-to-head comparison rests entirely on the Ultra 7's measured results and the architectural specifications of both processors. The Core 5's 8 cores and 16 threads, combined with a 4.00 GHz base clock and 5.50 GHz boost clock, define its expected performance envelope, but no empirical scores exist to quantify it.

The nearest rivals for the Core Ultra 7 270K Plus provide additional context for its standing. The Intel Xeon 6520P scores 93,786, a 0% delta from the Ultra 7, meaning these two processors are effectively tied in average score. The AMD EPYC 4564P sits 1.5% behind, the AMD EPYC 9175F trails by 1.9%, and the AMD EPYC 4565P is 2.1% lower. These narrow margins place the Core Ultra 7 270K Plus in the upper tier of desktop processors, competing directly with server-class silicon in aggregate throughput.

The Verdict

The data indicates that the Intel Core Ultra 7 270K Plus is the superior processor for essentially every measurable workload. Its 24 cores, 24 threads, and 36 MB of shared L3 cache give it a structural advantage over the Core 5 223PQE's 8 cores, 16 threads, and 24 MB of shared L3 cache. The 96th percentile ranking versus the 50th percentile ranking summarizes the gap: the Ultra 7 belongs to a different performance class entirely.

The Core Ultra 7 270K Plus also carries a higher memory bandwidth figure at 115.2 GB/s compared to 89.6 GB/s for the Core 5 223PQE. Both processors support ECC memory, but the Ultra 7 supports only DDR5 while the Core 5 supports both DDR4 and DDR5. The Ultra 7's PCIe implementation offers Gen 5 with 20 lanes, while the Core 5 offers Gen 5 with 16 lanes, giving the Ultra 7 additional expansion headroom. Its integrated graphics, Arc Xe-LPG Graphics with 64 execution units, is a newer architecture than the UHD Graphics 770 found in the Core 5.

The Core Ultra 7 270K Plus is also the only one of the two with an unlocked multiplier, which makes it the choice for users who intend to adjust clock speeds. Its 3 nm process node, fabricated by TSMC, stands against the 10 nm Intel process used for the Core 5 223PQE. The Ultra 7 integrates 17,800 million transistors on a 243 mm² die, specifications absent from the Core 5's record.

Where Each One Wins

The Core Ultra 7 270K Plus wins in all recorded benchmark categories. The multi-core Cinebench results, ranging from 6,656 in R15 to 44,253 in R23, show a processor built for heavily threaded workloads such as rendering, simulation, and compilation. The PassMark multithread score of 68,574 and the data compression score of 804,322 confirm that the Ultra 7 handles parallel data processing with ease.

The Core 5 223PQE offers no measured wins because the database contains no benchmark scores for it. However, its specifications suggest areas where it could be competitive. Its 5.50 GHz boost clock matches the Ultra 7 exactly, which could translate to competitive single-thread performance in lightly threaded applications, though the Ultra 7's recorded single-thread scores remain the only empirical evidence available. The Core 5's support for DDR4 memory gives it compatibility with older platforms, and its Intel Socket 1700 interface targets a different motherboard ecosystem than the Ultra 7's Socket 1851.

The Core 5 223PQE's 125 W TDP matches the Ultra 7's 125 W TDP, so both processors sit in the same power envelope. The Core 5 uses a 10 nm process node from Intel's own foundry, while the Ultra 7 uses a 3 nm node from TSMC, which typically suggests greater transistor density and efficiency for the latter.
