Intel Core 5 223PQE vs Intel Core Ultra 9 288V Comparison

Where Each One Wins

The Intel Core 5 223PQE and the Intel Core Ultra 9 288V occupy sharply different performance profiles. The recorded data shows that the Core Ultra 9 288V holds the majority of wins in the benchmark suite, with the Core 5 223PQE showing no listed wins in the head-to-head comparison. The wins count stands at 0 for the Core 5 223PQE and 0 for the Core Ultra 9 288V in the provided head-to-head section, but the benchmark table for the Ultra 9 contains 17 individual scores across Cinebench and Passmark tests.

The Core Ultra 9 288V delivers its strongest results in multi-threaded rendering and integer workloads. In Cinebench R23 multi-core, it scores 10178 points, and in Passmark multi-thread it records 19810. These figures place it in the 76th percentile among all CPUs in the database, with an average benchmark score of 23219. Its nearest rivals include the Intel Core i9-11900F with an average score of 23254 and a delta of -0.2%, the AMD EPYC 4124P at 23167 with a delta of 0.2%, the AMD Ryzen 7 5800H at 23277 with a delta of -0.2%, and the Intel Core Ultra 7 266V at 23297 with a delta of -0.3%. The Ultra 9's average score sits within a very tight band around these rivals, staying within a fraction of a percent of each.

The Core 5 223PQE has no benchmark scores in the database, meaning its performance cannot be quantified directly against the Ultra 9's recorded results. Its percentile rank of 50 against all CPUs indicates a mid-pack standing, but without actual benchmark data, the use-case split must rely on architectural characteristics rather than measured outcomes.

The Ultra 9 288V is a mobile processor with a 30 W TDP, making it suitable for thermally constrained systems. The Core 5 223PQE is a desktop part with a 125 W TDP, pointing to systems with active cooling and higher power budgets. The use-case split is therefore defined by platform: the Ultra 9 targets mobile workstations and thin laptops, while the Core 5 targets desktop towers.

Architecture Differences

The two processors come from different Intel design families and manufacturing processes. The Core 5 223PQE uses the Bartlett Lake codename with a 10 nm process node fabricated by Intel. The Core Ultra 9 288V uses Lunar Lake architecture with a 3 nm process node fabricated by TSMC. This process difference is substantial: the 3 nm node is more advanced than the 10 nm node, which typically allows for higher transistor density and improved power efficiency.

Core counts are identical at 8, but thread counts differ. The Core 5 223PQE supports 16 threads through simultaneous multithreading, while the Core Ultra 9 288V has 8 threads, matching its 8 cores without SMT. This means the Core 5 can process two threads per core, while the Ultra 9 processes one thread per core.

Clock speeds favor the Core 5 in both base and boost. The Core 5 runs at 4.00 GHz base and 5.50 GHz boost. The Ultra 9 runs at 3.30 GHz base and 5.10 GHz boost. These higher clocks on the Core 5 partially compensate for its older process node.

Cache configurations differ significantly. 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 9 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3 cache. The Ultra 9 has more L1 and L2 per core, while the Core 5 has twice the L3 cache.

Memory support diverges completely. The Core 5 supports DDR4 and DDR5 with dual-channel memory and 89.6 GB/s bandwidth, plus ECC memory support. The Ultra 9 supports LPDDR5X with dual-channel memory and 136.5 GB/s bandwidth, without ECC support. The Ultra 9's memory bandwidth is about 52% higher, which benefits integrated graphics and memory-intensive workloads.

PCIe connectivity shows a major gap. The Core 5 provides Gen 5 with 16 lanes from the CPU, while the Ultra 9 provides Gen 5 with only 4 lanes. The Core 5 is designed for discrete GPU and expansion, while the Ultra 9 is limited to basic connectivity.

Integrated graphics differ as well. The Core 5 uses UHD Graphics 770, while the Ultra 9 uses Arc 140V. The Arc 140V is a more capable integrated GPU, though the database does not contain specific graphics benchmark scores for either processor.

The Core 5 launches in the desktop market segment with a launch MSRP of $319. The Ultra 9 is a mobile part with no launch MSRP listed. Release dates are also separated: the Core 5 released in March 2026, while the Ultra 9 released in September 2024.

The Verdict

The data supports different picks depending on platform and workload. For mobile systems, the Core Ultra 9 288V is the only option between the two, as it uses a BGA 2833 socket designed for laptops. Its 30 W TDP fits thin-and-light designs, and its 136.5 GB/s memory bandwidth supports the Arc 140V integrated graphics.

For desktop systems, the Core 5 223PQE is the choice, using Intel Socket 1700 with 16 PCIe Gen 5 lanes for discrete graphics and expansion cards. Its 125 W TDP requires a desktop cooling solution, but the higher boost clock of 5.50 GHz and 16 threads provide compute headroom.

Benchmark results only exist for the Ultra 9, and they show a 76th percentile ranking with an average score of 23219. The nearest rivals all cluster within 0.3% of this score, indicating that the Ultra 9 performs at a level comparable to desktop parts like the Intel Core i9-11900F and the AMD Ryzen 7 5800H. The Core 5 has no benchmark scores, so its performance relative to these parts cannot be assessed from the database.

ECC memory support on the Core 5 makes it suitable for reliability-focused desktop builds. The Ultra 9 lacks ECC support, which is typical for mobile parts. The Core 5's larger 24 MB L3 cache may benefit workloads with large working sets, while the Ultra 9's per-core L1 and L2 caches are larger.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between these two processors, and the Core 5 223PQE has no individual benchmark scores. All recorded benchmark data belongs to the Core Ultra 9 288V, with 17 scores across Cinebench and Passmark tests.

In Cinebench R23 multi-core, the Ultra 9 scores 10178. Single-core R23 shows 1950. In Cinebench R20, multi-core scores 7069 and single-core scores 997. Cinebench R15 shows 1583 multi-core and 301.5 single-core.

Passmark results for the Ultra 9 include data compression at 186521, data encryption at 14141, extended instructions at 15613, find prime numbers at 195, floating point math at 59536, integer math at 44019, multi-thread at 19810, physics at 1637, random string sorting at 22622, and single thread at 4274.

These scores place the Ultra 9 at the 76th percentile among all CPUs, with an average benchmark score of 23219. Its nearest rival, the Intel Core i9-11900F, averages 23254, a delta of -0.2%. The AMD EPYC 4124P averages 23167, a delta of 0.2%. The AMD Ryzen 7 5800H averages 23277, a delta of -0.2%. The Intel Core Ultra 7 266V averages 23297, a delta of -0.3%. The Ultra 9's average score is therefore within a narrow 0.5% spread of all four nearest rivals, indicating performance parity with those established parts.

The Core 5 223PQE has no recorded benchmark scores and no nearest rivals in the database. Its percentile of 50 places it at the median of all CPUs, but without measured scores, direct comparison to the Ultra 9's 76th percentile ranking is not possible. The absence of benchmark data for the Core 5 means the head-to-head comparison cannot be resolved numerically. The Ultra 9's recorded performance confirms its standing among mid-range desktop and mobile processors from the previous generation, while the Core 5's capabilities must be inferred from its specifications alone.
