Specification Differences

The two processors differ across nearly every specification field in the database.

The Core 3 100HL uses 8 cores and 12 threads, while the Ultra 5 225T uses 10 cores and 10 threads. The Ultra 5 225T has more physical cores but no hyper-threading, resulting in fewer total threads. Base clocks differ: the Core 3 100HL runs at 2.10 GHz, while the Ultra 5 225T runs at 2.50 GHz. Boost clocks also favor the Ultra 5 225T at 4.90 GHz versus 4.60 GHz.

Thermal design power differs substantially. The Core 3 100HL is rated at 45W, while the Ultra 5 225T is rated at 65W. The sockets are incompatible: the Core 3 100HL uses Intel Socket 1700, while the Ultra 5 225T uses Intel Socket 1851.

Memory support diverges. The Core 3 100HL supports both DDR4 and DDR5, while the Ultra 5 225T supports only DDR5. Both use dual-channel memory buses. The Ultra 5 225T has a recorded memory bandwidth of 102.4 GB/s, while the Core 3 100HL has no bandwidth figure in the database.

PCIe connectivity differs significantly. The Core 3 100HL provides Gen 4 with 8 lanes (CPU only), while the Ultra 5 225T provides Gen 5 with 20 lanes (CPU only). Neither CPU supports ECC memory, and neither has an unlocked multiplier.

The integrated graphics differ. The Core 3 100HL uses Iris Xe Graphics with 48 execution units. The Ultra 5 225T uses Arc Xe-LPG Graphics with 16 execution units. Both are desktop market segment parts with active production status.

Release dates differ by roughly nine months. The Core 3 100HL was released in April 2024, while the Ultra 5 225T was released in December 2024.

Architecture Differences

The architectural divide between these two CPUs is substantial. The Core 3 100HL uses Raptor Lake architecture, specifically the Raptor Lake-PS codename. The Ultra 5 225T uses Arrow Lake architecture with the Arrow Lake-S codename. These represent different design generations from Intel.

The manufacturing process differs sharply. The Core 3 100HL is built on a 10 nm process at Intel's foundry. The Ultra 5 225T is built on a 3 nm process at TSMC. The database records the Ultra 5 225T's transistor count at 17,800 million and die size at 243 mm². The Core 3 100HL has no recorded transistor count or die size.

Cache hierarchies differ across all levels. The Core 3 100HL has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The Ultra 5 225T has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 20 MB of shared L3 cache. The larger per-core caches on the Ultra 5 225T support its higher single-thread performance.

The core count difference (10 versus 8) combines with the architectural generation gap to produce the observed multi-core performance delta. The Ultra 5 225T's smaller process node allows higher clock speeds at a higher TDP, contributing to its 32% Cinebench multi-core advantage.

The Ultra 5 225T belongs to the Core Ultra Series 2, a designation that reflects its newer architecture. The Core 3 100HL carries the standard Core 3 branding from the Raptor Lake generation. Both CPUs have locked multipliers, meaning overclocking is not supported through the multiplier.

The Verdict

The benchmark data directs a clear choice. The Intel Core Ultra 5 225T outperforms the Intel Core 3 100HL in every recorded workload, with margins ranging from 5.4% in integer math to 83.1% in prime number finding. The average benchmark score difference is 30,468 versus 23,545, a roughly 29% overall advantage.

Buyers needing the strongest single-thread performance for responsive desktop use should choose the Ultra 5 225T. Its 32% Cinebench single-core lead and 14.1% PassMark single-thread lead indicate faster application launching and snappier day-to-day operation.

Users running multi-threaded workloads such as video encoding, 3D rendering, or software compilation should also choose the Ultra 5 225T. The 32% Cinebench R23 multi-core lead and 30.6% PassMark multi-thread lead translate to meaningfully shorter render times and faster batch processing.

The Core 3 100HL's only advantages are qualitative. It supports DDR4 memory, which may allow reuse of existing memory modules. It has a lower 45W TDP versus 65W, which can simplify cooling requirements. Its 48 execution unit integrated graphics outclass the Ultra 5 225T's 16 EU Arc graphics for light gaming or media tasks without a discrete GPU.

The PCIe differences matter for expansion. The Ultra 5 225T's Gen 5 with 20 lanes provides more bandwidth and more connectivity than the Core 3 100HL's Gen 4 with 8 lanes. Systems needing many NVMe drives or high-bandwidth add-in cards should favor the Ultra 5 225T.

The socket incompatibility means these CPUs require different motherboards. The Core 3 100HL works with Intel Socket 1700 boards, while the Ultra 5 225T requires Intel Socket 1851. Platform choice will likely determine which CPU is practical for any given build.

The database shows the Ultra 5 225T at the 82nd percentile of all CPUs versus the 76th percentile for the Core 3 100HL. The nearest rival comparisons confirm the gap: the Core 3 100HL trades blows with mobile and older desktop parts like the Ryzen 7 5800H, while the Ultra 5 225T matches the Core i9-11980HK. For any workload measured in this database, the Ultra 5 225T is the stronger processor.
