Intel Core 5 223PE vs Intel Core 9 273PQE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core 9 273PQE across all 17 benchmark comparisons. The Intel Core 5 223PE does not register a single winning result in any test, making the performance gap both consistent and unambiguous. The magnitude of the lead, however, varies significantly by workload type, which is where the analysis gets interesting.

In the Cinebench series, the Core 9 273PQE delivers a uniform 32.5% advantage across all six tests. The R15 multicore result shows 3950 against 2666 for the Core 5 223PE, while the single-core R15 score is 557 versus 376. Moving to R20, the multicore score reaches 16459 compared to 11111, and the single-core test shows 2323 against 1568. The R23 multicore result is 39190 versus 26455, with single-core at 5532 versus 3734. This consistent 32.5% delta across both single-threaded and multi-threaded Cinebench tests indicates that the advantage comes from a combination of higher clock speeds and additional cores, both of which scale equally across these render workloads.

The PassMark suite reveals a more varied picture. The largest gap appears in data compression, where the Core 9 273PQE scores 585752 against 346623, a 40.8% lead. Integer math shows a similar 39.4% advantage with 164629 versus 99819. Floating-point math delivers 125546 versus 76468, a 39.1% gap. Data encryption shows 29636 versus 18448, a 37.8% lead. Extended instructions land at 38743 versus 24672, a 36.3% difference.

The smallest gaps appear in tests that rely more heavily on single-thread efficiency. The PassMark single-thread test shows 4573 versus 4219, a 7.7% lead for the Core 9 273PQE. Physics testing shows 2754 versus 2493, a 9.5% gap. Prime number finding shows 198 versus 159, a 19.7% difference. Random string sorting shows 53167 versus 35798, a 32.7% gap. The multithread score shows 46107 versus 31124, a 32.5% lead.

The pattern is clear. The Core 9 273PQE gains its largest victories in heavily parallel workloads that stress memory bandwidth and core count, while its smallest advantages appear in latency-sensitive single-core tasks. The 7.7% single-thread lead is modest compared to the 40.8% compression lead, suggesting that the Core 5 223PE remains competitive for lightly threaded applications but falls behind substantially when all resources are engaged.

Architecture Differences

Both processors share the Bartlett Lake codename and are built on Intel's 10 nm process node, but the internal configurations diverge significantly. The Core 5 223PE provides 8 cores and 16 threads, while the Core 9 273PQE doubles the core count to 12 cores with 24 threads. This 50% increase in cores and threads directly explains the large multicore benchmark gaps.

Clock speeds also favor the Core 9 273PQE substantially. The Core 5 223PE has a base clock of 2.90 GHz and boosts to 5.20 GHz. The Core 9 273PQE operates at a base clock of 3.40 GHz with a boost of 5.90 GHz. The higher base clock matters for sustained workloads that cannot maintain boost frequencies, while the higher boost clock explains the single-core benchmark advantage.

Cache allocation follows the core count difference. Both processors use 80 KB of L1 cache per core and 2 MB of L2 per core, but the shared L3 cache scales significantly. The Core 5 223PE has 24 MB of shared L3, while the Core 9 273PQE has 36 MB. This 12 MB difference provides the larger processor with more room for frequently accessed data, which benefits workloads with large working sets.

The thermal envelope differs as well. The Core 5 223PE has a 65 W TDP, while the Core 9 273PQE has a 125 W TDP. The higher power budget allows the Core 9 273PQE to maintain its higher clocks across more cores simultaneously, which is essential for the observed multicore performance advantage.

Both processors share several architectural traits. Each uses dual-channel memory with support for DDR4 and DDR5, and the memory bandwidth is identical at 89.6 GB/s. Both support ECC memory. Both use the Intel Socket 1700 platform. PCIe support is identical with Gen 5 and 16 CPU lanes. Neither processor has an unlocked multiplier.

The integrated graphics differ between the two. The Core 5 223PE includes UHD Graphics 730, while the Core 9 273PQE steps up to UHD Graphics 770. Both processors are marked as Active production status and share the same release date of 2026-03-08. The Core 5 223PE has part number SA4QF, while the Core 9 273PQE uses SA4Q9.

Where Each One Wins

The Core 9 273PQE wins every benchmark category, but the degree of dominance depends on the workload type. The database shows that data compression is where the Core 9 273PQE has its largest relative advantage at 40.8%. This makes sense given the 50% core advantage and larger L3 cache. Integer math and floating-point math follow closely at 39.4% and 39.1% respectively, reinforcing that the Core 9 273PQE excels in compute-heavy parallel workloads.

The Core 5 223PE narrows the gap most in single-thread performance. The PassMark single-thread test shows only a 7.7% difference, and the physics test shows a 9.5% gap. This means that for applications that rely on a single core's clock speed, the Core 5 223PE is nearly competitive. The 5.20 GHz boost clock is only 0.70 GHz lower than the Core 9 273PQE's 5.90 GHz boost, and the architectural similarities on the same process node keep single-core efficiency close.

The Core 5 223PE also shows relative strength in prime number finding, with a 19.7% deficit rather than the 30%+ gaps seen elsewhere. This suggests that the workload's dependency on cache latency and branch prediction is less sensitive to the core count difference. The Core 5 223PE's 24 MB L3 still provides substantial cache capacity, even though it is 12 MB smaller than the Core 9 273PQE's 36 MB.

The random string sorting test shows a 32.7% gap, which is close to the Cinebench average of 32.5%. This indicates that memory access patterns and memory bandwidth constraints affect this workload similarly to render workloads. Since both processors share the same 89.6 GB/s memory bandwidth, the Core 9 273PQE's advantage here comes from its higher core count and larger cache rather than raw memory throughput.

For users running single-threaded productivity applications, the Core 5 223PE remains a capable choice with only a modest deficit. For users running heavily threaded workloads such as video encoding, scientific computing, or large database operations, the Core 9 273PQE's advantage grows to roughly 40%, making it clearly superior.
