Intel Core 5 223PTE vs Intel Core Ultra 7 155HL Comparison

Where Each One Wins

The recorded data shows a split between two very different processor designs. The Intel Core 5 223PTE is built around a smaller core count but a much higher boost clock, while the Intel Core Ultra 7 155HL relies on a larger core and thread pool with a lower maximum frequency. Neither part has a benchmark score in the database, and there are no head-to-head benchmark results recorded. That means the analysis must rely on the architectural and specification differences alone.

The Core 5 223PTE wins in the single-thread-oriented scenario. Its 5.40 GHz boost clock is substantially higher than the 4.80 GHz boost clock of the Core Ultra 7 155HL. For workloads where a single core dictates the pace, such as lightly threaded applications, the data indicates the Core 5 223PTE should be the stronger performer. The higher clock allows faster instruction execution per core, and the 45 W TDP is identical, so the frequency advantage is not offset by a larger power envelope.

The Core Ultra 7 155HL wins in the multi-threaded scenario. It has 16 cores and 22 threads, compared to 8 cores and 16 threads for the Core 5 223PTE. The thread count advantage is 37.5% more threads, and the core count advantage is 100% more cores. For heavily parallel workloads, such as video encoding, 3D rendering, or compilation, the larger thread pool should allow the Core Ultra 7 155HL to split work across more execution units. Even with a lower boost clock, the sheer number of available threads gives it a clear edge in parallel throughput.

The integrated graphics comparison also favors the Core Ultra 7 155HL. It carries Arc Xe-LPG 128EU graphics, whereas the Core 5 223PTE uses UHD Graphics 770. The Arc Xe-LPG 128EU is a larger GPU block, suggesting better performance for graphics tasks or media acceleration. That said, the Core 5 223PTE has a more capable PCIe interface: Gen 5 with 16 lanes, versus Gen 4 with 8 lanes for the Core Ultra 7 155HL. For discrete GPU or NVMe connectivity, the Core 5 223PTE offers more bandwidth.

Memory support also differs. The Core 5 223PTE supports DDR4 and DDR5, while the Core Ultra 7 155HL supports DDR5 only, with the database noting that the actual memory type depends on the motherboard. ECC memory is supported on the Core 5 223PTE but not on the Core Ultra 7 155HL, which matters for reliability-sensitive workloads.

Architecture Differences

The two processors come from different architectural lineages. The Core 5 223PTE is based on the Bartlett Lake codename, which belongs to the Core 5 generation. The Core Ultra 7 155HL uses the Meteor Lake architecture with the Meteor Lake-PS codename, part of the Core Ultra Series 1 generation.

The process node differs: the Core 5 223PTE is fabricated on a 10 nm process, while the Core Ultra 7 155HL uses a 7 nm process. Both are made by Intel. The smaller process node on the Core Ultra 7 155HL suggests denser transistor packing, although the database does not record transistor counts or die sizes for either part.

Cache hierarchies show both similarities and differences. The L1 cache is 80 KB per core for the Core 5 223PTE and 112 KB per core for the Core Ultra 7 155HL. The L2 cache is identical at 2 MB per core. The L3 cache is also identical at 24 MB shared. That means the total cache per core is higher on the Core Ultra 7 155HL for L1, but the shared L3 is the same. For the Core 5 223PTE with 8 cores, the L3 pool is shared across fewer cores, giving each core more L3 headroom. For the Core Ultra 7 155HL with 16 cores, the same 24 MB L3 is shared across double the cores.

The sockets are incompatible. The Core 5 223PTE uses Intel Socket 1700, while the Core Ultra 7 155HL uses Intel Socket 1851. This is a fundamental platform split: a motherboard designed for one will not accept the other. The PCIe generation also differs, as noted, with Gen 5 for the Core 5 223PTE and Gen 4 for the Core Ultra 7 155HL. The Core 5 223PTE provides 16 CPU-only lanes; the Core Ultra 7 155HL provides 8 CPU-only lanes.

Both parts are desktop market segment processors, both are active in production, and neither has an unlocked multiplier. The Core 5 223PTE has a part number of SA4QL, and the Core Ultra 7 155HL has a part number of SRN2Z.

Head-to-Head Benchmarks

The database currently records no head-to-head benchmark results between the Intel Core 5 223PTE and the Intel Core Ultra 7 155HL. There are no benchmark scores for either part, and the wins counter shows zero wins for each. The average benchmark score for both is zero, and the percentile versus all CPUs is 50 for both, which represents the median position in the database distribution.

Given the absence of measured performance data, the analysis must project from specifications. The largest single-thread advantage for the Core 5 223PTE comes from the boost clock. The difference of 0.60 GHz between 5.40 GHz and 4.80 GHz is a 12.5% higher maximum frequency. In a single-threaded workload, that could translate to a noticeable performance lead, assuming IPC is similar.

The largest multi-thread advantage for the Core Ultra 7 155HL comes from the core and thread counts. With 16 cores versus 8 cores, the Core Ultra 7 155HL has 100% more cores. With 22 threads versus 16 threads, it has 37.5% more threads. The thread count difference is smaller than the core count difference because the Core 5 223PTE has Hyper-Threading (16 threads from 8 cores), while the Core Ultra 7 155HL also uses Hyper-Threading but with a different core configuration (22 threads from 16 cores). The thread-per-core ratio is 2.0 for the Core 5 223PTE and 1.375 for the Core Ultra 7 155HL, suggesting the Core Ultra 7 155HL has some cores without Hyper-Threading.

The base clock difference works in the opposite direction. The Core 5 223PTE has a base clock of 2.30 GHz, while the Core Ultra 7 155HL has a base clock of 1.40 GHz. That is a 0.90 GHz difference, or 64.3% higher base clock for the Core 5 223PTE. In sustained all-core workloads at base frequency, the Core 5 223PTE should be ahead per core, but the Core Ultra 7 155HL has twice the cores.

Memory bandwidth is identical at 89.6 GB/s for both, and both use dual-channel memory. That removes memory bandwidth as a differentiator.

The Verdict

The data points to a clear use-case split. For single-threaded performance, the Intel Core 5 223PTE is the better choice. Its 5.40 GHz boost clock is the highest frequency in this comparison, and its smaller core count means the shared 24 MB L3 cache is divided across only 8 cores, giving each core more L3 resource. The Core 5 223PTE also supports ECC memory and both DDR4 and DDR5, making it more flexible for reliability-sensitive or mixed-memory environments. Its Gen 5 PCIe with 16 lanes provides more bandwidth for expansion.

For multi-threaded performance, the Intel Core Ultra 7 155HL is the better choice. Its 16 cores and 22 threads provide a substantial parallel advantage. The 7 nm process node and larger L1 cache per core (112 KB versus 80 KB) suggest architectural refinement. The Arc Xe-LPG 128EU integrated graphics is more capable than UHD Graphics 770, making it stronger for GPU-adjacent workloads.

The sockets are incompatible, so the motherboard choice dictates the processor. A Socket 1700 platform with DDR4 or DDR5 support pairs with the Core 5 223PTE. A Socket 1851 platform with DDR5 support pairs with the Core Ultra 7 155HL. The Core 5 223PTE released later (2026-03-08) than the Core Ultra 7 155HL (2024-04-07), but both are active in production.

The launch MSRP is $232 for the Core 5 223PTE and $438 for the Core Ultra 7 155HL. The database records no benchmark scores for either part, so performance estimates come from the specification deltas. The Core 5 223PTE leads on frequency, memory flexibility, ECC, and PCIe bandwidth. The Core Ultra 7 155HL leads on core count, thread count, process node, L1 cache, and integrated graphics. Neither part has an unlocked multiplier, so overclocking is not a factor in the comparison.

For a user prioritizing raw single-thread speed and platform flexibility, the Core 5 223PTE is the data-supported pick. For a user prioritizing parallel throughput and integrated graphics capability, the Core Ultra 7 155HL is the data-supported pick. The absence of measured benchmarks means the final decision hinges on workload type and motherboard compatibility.
