Intel Core 3 100UL vs Intel Core 5 223PQE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the Intel Core 3 100UL and the Intel Core 5 223PQE. Both processors return an average benchmark score of 0, and neither has any entries in the head-to-head benchmark table. This absence of measured data means the comparison must rely entirely on the architectural specifications and feature sets recorded for each part.

The Intel Core 5 223PQE holds a clear structural advantage in core count. It provides 8 cores and 16 threads, while the Intel Core 3 100UL provides 6 cores and 8 threads. That translates to 2 additional physical cores and 8 additional threads, a substantial difference for workloads that scale with parallel execution. The thread count gap is particularly large because the Core 5 223PQE doubles the thread-per-core ratio (2 threads per core) compared to the Core 3 100UL, which uses a 1.33 threads-per-core configuration typical of hybrid or efficiency-oriented designs.

Clock rates also favor the Core 5 223PQE decisively. The base clock is 4.00 GHz versus 1.20 GHz for the Core 3 100UL, a 3.33x difference at the floor. The boost clock is 5.50 GHz versus 4.50 GHz, a 1.22x difference at the ceiling. These numbers indicate that the Core 5 223PQE is designed for sustained high-frequency operation, while the Core 3 100UL prioritizes low-power operation at its 15 W TDP. The Core 5 223PQE carries a 125 W TDP, which is 8.33x higher than the Core 3 100UL. That power envelope allows the higher clocks and larger core count to operate without thermal throttling under load.

Cache hierarchy differences reinforce the performance gap. The Core 3 100UL has 1.25 MB of L2 cache per core and 10 MB of shared L3 cache. The Core 5 223PQE has 2 MB of L2 cache per core and 24 MB of shared L3 cache. Total L2 capacity, calculated from per-core values, is 7.5 MB for the Core 3 100UL (6 cores times 1.25 MB) and 16 MB for the Core 5 223PQE (8 cores times 2 MB). The L3 cache difference is 2.4x in favor of the Core 5 223PQE. Larger caches reduce memory latency and improve performance in data-intensive workloads, particularly for database queries, compilation, and simulation tasks.

Memory bandwidth is another differentiator. The Core 5 223PQE records a memory bandwidth of 89.6 GB/s, while the Core 3 100UL has no recorded bandwidth figure. Both support DDR4 and DDR5 memory in a dual-channel configuration, but the absence of a bandwidth number for the Core 3 100UL suggests it operates at lower effective memory speeds or lacks the same memory controller throughput. ECC memory support also differs: the Core 5 223PQE supports ECC, while the Core 3 100UL does not. ECC support is relevant for workstation and server-adjacent workloads where data integrity is critical.

PCIe connectivity favors the Core 5 223PQE as well. It provides Gen 5 with 16 lanes from the CPU, while the Core 3 100UL provides Gen 4 with 8 lanes. This is a 2x difference in lane count and a full generation jump in bandwidth per lane. Gen 5 PCIe doubles the per-lane data rate relative to Gen 4, so the Core 5 223PQE has substantially more I/O throughput for discrete GPUs, NVMe storage, and expansion cards.

The integrated graphics differ. The Core 3 100UL uses UHD Graphics 64EU, while the Core 5 223PQE uses UHD Graphics 770. The 770 designation typically indicates a higher execution unit count and higher clocked iGPU, though the database does not record specific EU counts for the 770. For light graphics workloads, the Core 5 223PQE likely provides better integrated graphics performance, but the data does not include benchmark scores to quantify this.

Where Each One Wins

The Intel Core 3 100UL wins in power efficiency. Its 15 W TDP is 8.33x lower than the Core 5 223PQE's 125 W TDP. For fanless or passively cooled systems, small-form-factor desktops, and always-on appliances, the lower power draw is a decisive factor. The 1.20 GHz base clock also indicates that the Core 3 100UL can idle or run light tasks at very low power consumption. It uses the same Intel Socket 1700 as the Core 5 223PQE, so it can fit into the same motherboard ecosystem, but its thermal footprint is far smaller.

The Intel Core 5 223PQE wins in almost every performance-oriented category. It has more cores, more threads, higher clocks, more cache, higher memory bandwidth, ECC support, and faster PCIe. The 5.50 GHz boost clock is the highest recorded speed among the two parts, and the 24 MB L3 cache is 2.4x larger than the Core 3 100UL's 10 MB. For multi-threaded rendering, video encoding, software compilation, virtualization, and scientific computing, the Core 5 223PQE is the clear choice based on specifications.

The Core 5 223PQE also wins in I/O expandability. Its Gen 5 PCIe with 16 lanes provides 2x the lane count and a faster generation compared to the Core 3 100UL's Gen 4 with 8 lanes. Systems that require multiple high-bandwidth devices, such as dual GPUs or multiple NVMe drives, will hit bandwidth limits on the Core 3 100UL much sooner.

The Core 5 223PQE supports ECC memory, a feature absent from the Core 3 100UL. For error-sensitive workloads like financial modeling, scientific research, or long-running server processes, ECC support is a requirement, not a luxury. This gives the Core 5 223PQE a clear functional advantage that the Core 3 100UL cannot match.

The Core 3 100UL has no recorded wins in benchmarks, and the Core 5 223PQE also has no recorded wins, because the head-to-head benchmark table is empty. The wins described here are derived from specification differences only.

Architecture Differences

The Core 3 100UL uses the Raptor Lake architecture with the codename Raptor Lake-PS, and its generation is listed as Core 3 (Raptor Lake-PS). The Core 5 223PQE uses the Bartlett Lake architecture with the codename Bartlett Lake, and its generation is listed as Core 5 (Bartlett Lake). Both are built on a 10 nm process node at Intel's foundry, but the architectures are distinct generations of Intel's core designs.

The Core 3 100UL is a Raptor Lake-PS part, which is a hybrid architecture that typically combines performance cores and efficiency cores. The 6-core, 8-thread configuration with a 1.20 GHz base clock indicates a mix of core types with different frequency characteristics. The Core 5 223PQE, as a Bartlett Lake part, uses a more conventional homogeneous core design with 8 cores and 16 threads, all capable of running at a 4.00 GHz base clock and 5.50 GHz boost.

The cache hierarchy reflects the architectural differences. The Core 5 223PQE has 2 MB of L2 per core, which is 1.6x larger than the Core 3 100UL's 1.25 MB per core. This suggests a newer or more robust core microarchitecture in the Bartlett Lake design. The L3 cache is 24 MB versus 10 MB, a 2.4x difference that indicates a larger shared cache pool for the Bartlett Lake part.

The memory controller differs in capability: the Core 5 223PQE supports ECC memory and records a bandwidth of 89.6 GB/s, while the Core 3 100UL does not support ECC and has no recorded bandwidth. The PCIe controller is also a full generation ahead on the Core 5 223PQE, with Gen 5 support versus Gen 4 on the Core 3 100UL.

The integrated graphics unit differs: the Core 3 100UL has UHD Graphics 64EU, while the Core 5 223PQE has UHD Graphics 770. Both are Intel integrated graphics solutions, but the 770 is a newer and more capable iGPU design within the Bartlett Lake platform.

Both processors use Intel Socket 1700, so they are physically compatible with the same motherboard socket. Both are desktop market segments and are currently marked as Active in production status. Neither processor has an unlocked multiplier. The Core 5 223PQE has a later release date by approximately two years, which aligns with the architectural generational gap between Raptor Lake-PS and Bartlett Lake.
