Intel Core 5 223PE vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The benchmark data presents a one-sided contest. The Intel Core Ultra 9 285 wins all 17 recorded head-to-head comparisons. The most significant margins appear in workloads that scale with core count and memory bandwidth. In Cinebench R23 multi-core, the Core Ultra 9 285 scores 48,945 against the Core 5 223PE's 26,455, a 45.9% advantage. The single-core gap is similarly decisive: 6,909 versus 3,734 in Cinebench R23 single-core, a 46% difference. These results indicate that the Core Ultra 9 285 delivers roughly double the throughput in both lightly threaded and heavily threaded rendering tasks.

PassMark tests reinforce this pattern. Data encryption shows the largest relative gap: the Core Ultra 9 285 scores 46,949, which is 60.7% higher than the Core 5 223PE's 18,448. Floating point math follows closely, with the Core Ultra 9 285 at 194,988 versus 76,468, a 60.8% delta. Prime number search, a test sensitive to integer throughput and cache behavior, shows a 65.4% gap (459 versus 159). These are not marginal differences; they indicate a fundamentally different performance class.

The narrowest margins still favor the Core Ultra 9 285. PassMark single-thread shows 4,881 versus 4,219, a 13.6% lead. Integer math shows 164,869 versus 99,819, a 39.5% gap. Physics simulation, which often reflects combined CPU and memory performance, shows a 30.7% advantage (3,598 versus 2,493). Even in the closest test, the Core Ultra 9 285 maintains a clear lead, suggesting that its architectural advantages extend beyond raw core count.

The average benchmark scores confirm the hierarchy. The Core Ultra 9 285 averages 75,488 across all recorded tests, placing it in the 95th percentile of all CPUs in the database. The Core 5 223PE averages 40,585, placing it in the 87th percentile. The nearest rivals for the Core 5 223PE include the Intel Core 7 253PE (0.1% higher average score), the Intel Xeon 6357P (0.1% lower), and the AMD Ryzen AI 5 PRO 435G (0.3% lower). For the Core Ultra 9 285, the nearest rivals are all EPYC or Ryzen PRO parts, with deltas under 0.3%. This positioning shows that the Core Ultra 9 285 competes against server-class and high-end workstation silicon, while the Core 5 223PE sits in the upper mainstream segment.

Architecture Differences

The two processors diverge across every major architectural axis. The Core 5 223PE uses the Bartlett Lake codename with 8 cores and 16 threads, built on Intel's 10 nm process. The Core Ultra 9 285 uses the Arrow Lake-S codename with 24 cores and 24 threads, built on TSMC's 3 nm process. The core count difference is 16 additional cores for the Core Ultra 9 285, but thread count tells a different story: the Core 5 223PE has 16 threads from 8 cores (likely with Hyper-Threading), while the Core Ultra 9 285 has 24 threads from 24 cores (no simultaneous multithreading). This means the Core Ultra 9 285 relies on physical cores for parallelism rather than logical threads.

Cache configurations differ substantially. The Core 5 223PE provides 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. The Core Ultra 9 285 provides 192 KB L1 per core, 3 MB L2 per core, and 36 MB shared L3. The larger per-core L1 and L2 caches on the Core Ultra 9 285 likely contribute to its single-thread advantage, while the 12 MB larger shared L3 helps with multi-threaded data sharing. Transistor count and die size are only recorded for the Core Ultra 9 285: 17,800 million transistors on a 243 mm² die, produced by TSMC. The Core 5 223PE has no transistor or die size data in the database.

Memory support also separates the two. The Core 5 223PE supports both DDR4 and DDR5, while the Core Ultra 9 285 supports DDR5 only. Both use dual-channel memory buses, but the Core Ultra 9 285 records 102.4 GB/s of memory bandwidth versus 89.6 GB/s for the Core 5 223PE. This 12.8 GB/s difference (about 14% higher) aligns with the Core Ultra 9 285's advantage in memory-sensitive tests like data encryption and random string sorting.

PCIe capabilities differ as well. The Core 5 223PE offers Gen 5 with 16 lanes (CPU only), while the Core Ultra 9 285 offers Gen 5 with 20 lanes (CPU only). The Core Ultra 9 285 provides 4 additional PCIe Gen 5 lanes, which may matter for multi-GPU or high-speed storage configurations. Integrated graphics differ: the Core 5 223PE uses UHD Graphics 730, while the Core Ultra 9 285 uses Arc Xe-LPG Graphics 64EU. Both support ECC memory, a feature shared across the two desktop parts.

Socket compatibility is completely separate. The Core 5 223PE uses Intel Socket 1700, while the Core Ultra 9 285 uses Intel Socket 1851. These are not interchangeable platforms. The Core Ultra 9 285 belongs to the Core Ultra Series 2 generation, while the Core 5 223PE is a Bartlett Lake part. The release dates differ by over a year: the Core Ultra 9 285 launched on 2024-12-31, while the Core 5 223PE launched on 2026-03-08. Both parts remain in active production.

The Verdict

The data supports a clear split in intended use. The Core Ultra 9 285 is the superior processor for every recorded benchmark. Its 24 physical cores, larger caches, higher memory bandwidth, and 3 nm process node deliver between 13.6% and 65.4% higher scores depending on the workload. The percentile rankings confirm this: 95th versus 87th percentile of all CPUs. For any workload represented in the database, the Core Ultra 9 285 is the correct choice.

The Core 5 223PE has no benchmark wins. Its only recorded advantages are platform-level: support for DDR4 memory, a lower launch MSRP of $232 versus the Core Ultra 9 285's $579, and a different socket that may align with older motherboards. The Core 5 223PE also draws the same 65 W TDP as the Core Ultra 9 285, which means the performance gap comes without a power penalty. However, the data does not show any scenario where the Core 5 223PE outperforms the Core Ultra 9 285.

The nearest rivals for each part suggest different competitive contexts. The Core 5 223PE sits alongside the Intel Core 7 253PE and Intel Xeon 6357P, with average scores within 0.3% of each other. The Core Ultra 9 285 sits alongside AMD EPYC 8224P and EPYC 4545P, with average scores within 0.3% of the Core Ultra 9 285. These rival positions indicate that the Core 5 223PE targets mid-range desktops, while the Core Ultra 9 285 targets high-end workstations and entry-level servers.

Where Each One Wins

The Intel Core Ultra 9 285 wins everywhere in the recorded benchmarks. Its largest advantages appear in PassMark data encryption (60.7% higher), floating point math (60.8% higher), and find prime numbers (65.4% higher). These workloads benefit from the combination of 24 physical cores, larger L1 and L2 caches per core, and the 3 nm process node. The Core Ultra 9 285 also leads in multi-threaded rendering by roughly 46% across all three Cinebench versions (R15, R20, R23).

The Intel Core 5 223PE has no benchmark victories, but its platform characteristics suggest specific use cases where it may be preferable. The DDR4 support means it can be paired with older memory infrastructure, which may matter for legacy system upgrades. The Intel Socket 1700 platform may have broader motherboard availability compared to the newer Intel Socket 1851. The lower launch MSRP of $232 makes it a less expensive entry point, though the data shows the Core Ultra 9 285 delivers substantially higher performance per unit of TDP (both are 65 W).

For workloads that are memory-bandwidth bound, the Core Ultra 9 285's 102.4 GB/s versus 89.6 GB/s provides a measurable edge. For workloads that are cache sensitive, the larger L3 (36 MB versus 24 MB) and larger per-core L2 (3 MB versus 2 MB) favor the Core Ultra 9 285. For workloads that are limited by single-core speed, the Core Ultra 9 285's 13.6% PassMark single-thread lead and 46% Cinebench R23 single-core lead make it the clear pick.
