Intel Core 5 223PE vs Intel Core 7 251TE Comparison

Where Each One Wins

The benchmark split between these two Bartlett Lake desktop parts is unusually lopsided. The Intel Core 5 223PE takes 13 of the 17 recorded head-to-head tests, while the Intel Core 7 251TE wins only 4. Yet the nature of those wins tells a clear story about what each processor is built for.

The Core 5 223PE dominates in nearly every content-creation and general-purpose workload. Cinebench results are consistently in its favor, with the R15, R20, and R23 multi-core tests all showing a 3.5% advantage. Single-core performance follows the same pattern, with margins between 3.5% and 3.7% across all three Cinebench versions. The PassMark single-thread test shows a much larger gap, with the Core 5 leading by 15.4%. This is a processor that simply has higher per-thread throughput, and it shows in everyday responsiveness.

The Core 5 also wins the PassMark multi-thread test by 3.5%, the data compression test by 3.5%, and the physics test by a commanding 22.3%. The extended instructions test is its biggest victory, with a 31.2% lead. Prime number finding goes to the Core 5 as well, with an 11.9% edge. This pattern suggests the Core 5 has a more efficient core design despite having far fewer cores.

The Core 7 251TE, by contrast, wins in specialized math-heavy workloads where raw core count can flex its muscles. The integer math test shows a 26% advantage, floating point math comes in 12% ahead, and random string sorting is 10.7% faster. Data encryption is its most decisive win at 20.2%. These are workloads that scale across many threads, and the Core 7 has 24 cores versus 8 on the Core 5.

For users who primarily render, compress files, or run general productivity suites, the Core 5 223PE is the stronger choice according to the recorded data. For encryption, heavy integer math, and large sorting operations, the Core 7 251TE pulls ahead. The overall average benchmark scores are close, with the Core 7 at 41650 and the Core 5 at 40585, a difference of roughly 2.6% in favor of the Core 7, but the per-workload distribution is what matters for real-world selection.

Architecture Differences

Both processors are built on Intel's 10 nm process and share the Bartlett Lake codename. They also share the same Intel Socket 1700 platform. The core architecture, however, diverges significantly in configuration.

The Core 7 251TE deploys 24 cores with 32 threads, indicating a hybrid arrangement where not all cores are identical. The Core 5 223PE uses 8 cores with 16 threads, which suggests a simpler symmetric layout. Both use the same 80 KB L1 cache per core, but the L2 allocation differs: the Core 7 provides 1.25 MB per core, while the Core 5 provides 2 MB per core. That larger per-core L2 on the Core 5 likely contributes to its strong single-thread results, as each core has more dedicated cache for its working set.

L3 cache is also split differently. The Core 7 holds 36 MB shared, while the Core 5 holds 24 MB shared. Even with less total L3, the Core 5's higher L2 per core and higher base clock of 2.90 GHz versus 1.40 GHz on the Core 7 give it a per-thread advantage that shows up consistently across the benchmark suite.

The die size for the Core 7 is listed at 215 mm², while the Core 5 does not have a recorded die size. Both support DDR4 and DDR5 memory in dual-channel configuration with 89.6 GB/s bandwidth. PCIe support is identical: Gen 5 with 16 lanes from the CPU only.

The production status for both is Active. The Core 7 was released on January 12, 2025, while the Core 5 has a later release date of March 8, 2026. The Core 7's part number is SRQAXQ5ZG, and the Core 5's is SA4QF.

Neither processor has an unlocked multiplier, so overclocking is not part of the package. Both are desktop market segments.

Specification Differences

The two processors differ in several key specifications. Core count is the most obvious: 24 cores for the Core 7 251TE versus 8 cores for the Core 5 223PE. Thread count follows with 32 versus 16.

Base clocks are dramatically different. The Core 7 runs at 1.40 GHz base, while the Core 5 runs at 2.90 GHz. Boost clocks are closer, with the Core 7 reaching 5.40 GHz and the Core 5 reaching 5.20 GHz.

Thermal design power differs as well. The Core 7 is rated at 45 W TDP, while the Core 5 is rated at 65 W TDP. This is notable because the Core 5 achieves its benchmark wins with a higher TDP envelope, while the Core 7 packs more cores into a lower power limit.

L2 cache per core is 1.25 MB on the Core 7 versus 2 MB on the Core 5. Total L3 cache is 36 MB on the Core 7 versus 24 MB on the Core 5.

Integrated graphics differ: UHD Graphics 770 on the Core 7, UHD Graphics 730 on the Core 5.

The launch MSRP for the Core 7 251TE is $384. The launch MSRP for the Core 5 223PE is $232.

Every other specification is shared: dual-channel memory bus, 89.6 GB/s bandwidth, DDR4 and DDR5 support, ECC memory support, Gen 5 PCIe with 16 lanes, 10 nm process, Intel Socket 1700, and Bartlett Lake codename.

Across all three Cinebench versions, the Core 5 wins by a consistent 3.5% in multi-core and between 3.5% and 3.7% in single-core. R15 multi-core shows 2666 versus 2572. R20 multi-core shows 11111 versus 10717. R23 multi-core shows 26455 versus 25518. The R15 single-core result is 376 versus 362, R20 single-core is 1568 versus 1512, and R23 single-core is 3734 versus 3602.

The Core 5 also wins PassMark multi-thread with 31124 versus 30022, a 3.5% edge, and data compression with 346623 versus 334399, also 3.5%.

For the Intel Core 7 251TE, the biggest win is in PassMark data encryption, scoring 22176 against 18448, a 20.2% advantage. Integer math goes to the Core 7 by 26%, with 125739 versus 99819. Floating point math is 12% ahead at 85607 versus 76468. Random string sorting shows 39643 versus 35798, a 10.7% lead.

The overall benchmark averages reflect this split: the Core 7 holds an average benchmark score of 41650, while the Core 5 sits at 40585. The Core 7 ranks in the 88th percentile of all CPUs, and the Core 5 ranks in the 87th percentile. Nearest rivals for the Core 7 include the Intel Core Ultra 7 265H at 41621 (0.1% delta) and the Intel Core i7-12850HX at 41779 (negative 0.3% delta). Nearest rivals for the Core 5 include the Intel Core 7 253PE at 40557 (0.1% delta) and the AMD Ryzen AI 5 PRO 435G at 40718 (negative 0.3% delta).

The recorded data shows a processor with fewer cores but higher clocks and more L2 per core outperforming a higher-core-count part in most tested workloads. The Core 5 223PE is the better all-rounder for Cinebench-style rendering and general threaded work, while the Core 7 251TE is specialized for encryption, math, and sorting tasks where core count trumps per-core efficiency.
