Intel Core 3 100UL vs Intel Core Ultra 5 336H Comparison

The Verdict

The Core 3 100UL and Core Ultra 5 336H serve entirely different segments, and the benchmark data makes the separation clear. The Core 3 100UL is a desktop-oriented 6-core part with a 15 W TDP, positioned for basic computing tasks where low power consumption and a socketed platform matter more than raw throughput. The Core Ultra 5 336H is a mobile processor with 16 cores, a 25 W TDP, and a 3 nm Panther Lake architecture that places it in the 84th percentile among all CPUs. The data shows the Core Ultra 5 336H is the obvious choice for any workload that demands multithreaded performance, while the Core 3 100UL fits scenarios where the desktop Socket 1700 platform and lower power envelope are priorities. The Core 3 100UL has no recorded benchmark scores or nearest rivals in the database, so all quantitative comparisons come from the Core Ultra 5 336H's recorded results.

Architecture Differences

The two processors come from different architectural generations and target different physical formats. The Core 3 100UL uses Raptor Lake architecture on a 10 nm process, built for Intel Socket 1700, which is a desktop platform. The Core Ultra 5 336H uses Panther Lake architecture on a 3 nm process, built for Intel BGA 2540, which is a mobile platform. The process node difference is significant: 10 nm versus 3 nm represents a substantial generational leap in transistor density and power efficiency.

Core counts differ sharply. The Core 3 100UL has 6 cores and 8 threads, while the Core Ultra 5 336H has 16 cores and 16 threads. The Core Ultra 5 336H does not use hyper-threading (16 threads across 16 cores), while the Core 3 100UL does (8 threads across 6 cores). Cache allocations also favor the newer part: the Core 3 100UL has 80 KB L1 per core, 1.25 MB L2 per core, and 10 MB shared L3. The Core Ultra 5 336H has 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. That is 80% more L3 cache and roughly double the per-core L2.

Clock speeds tell a nuanced story. The Core 3 100UL has a base clock of 1.20 GHz and a boost clock of 4.50 GHz. The Core Ultra 5 336H has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The newer chip starts higher and boosts slightly higher, but the real advantage comes from having more than double the cores.

Memory support differs: the Core 3 100UL supports DDR4 and DDR5, while the Core Ultra 5 336H supports DDR5 and LPDDR5X. Both use dual-channel memory buses, but the Core Ultra 5 336H has a recorded memory bandwidth of 115.2 GB/s. The Core 3 100UL has no memory bandwidth figure in the database.

PCIe connectivity also diverges. The Core 3 100UL provides PCIe Gen 4 with 8 CPU-only lanes. The Core Ultra 5 336H provides PCIe Gen 5 with 12 CPU-only lanes. That is a full generation newer and 50% more lanes.

Integrated graphics differ: the Core 3 100UL uses UHD Graphics 64EU, while the Core Ultra 5 336H uses Intel Xe3 Graphics. The database records no benchmark scores for either iGPU, so no performance comparison is possible.

The Core Ultra 5 336H has a production status of Active and a release date of 2026-01-04. The Core 3 100UL also has Active production status and a release date of 2024-04-07. Neither part has a launch MSRP recorded.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two CPUs, and the Core 3 100UL has no individual benchmark scores at all. Therefore, all quantitative analysis comes from the Core Ultra 5 336H's recorded results and its position relative to its nearest rivals.

The Core Ultra 5 336H's average benchmark score is 34485, placing it at the 84th percentile of all CPUs. Its nearest rival is the Intel Core i7-13700HX with an average score of 34554, a delta of -0.2%, meaning the Core Ultra 5 336H trails by a negligible margin. The Intel Core i5-13450HX scores 34333, putting the Core Ultra 5 336H ahead by 0.4%. The AMD Ryzen 7 3700X scores 34260, a 0.7% deficit for the rival. The AMD Ryzen AI 7 350 scores 34222, placing it 0.8% behind the Core Ultra 5 336H.

Cinebench results for the Core Ultra 5 336H show strong scaling from single-core to multi-core loads. In Cinebench R15, it scores 341 single-core and 2418 multi-core. In R20, the scores are 1422 single-core and 10076 multi-core. In R23, the scores are 3387 single-core and 23991 multi-core. The multi-core to single-core ratio in R23 is roughly 7.1:1, which reflects the 16-core design's ability to spread heavy threaded work.

PassMark results reveal specific workload strengths. The data compression score is 280340. Data encryption scores 21291. Extended instructions score 24542. Floating point math scores 82415. Integer math scores 62070. Multithread score is 28545. Physics score is 2682. Random string sorting scores 34402. Single-thread score is 4013 (recorded twice as passmark_single_thread and passmark_singlethread, both with identical values). Find prime numbers scores only 299, which is a relatively weak result compared to the other PassMark subtests and suggests a specific limitation in that workload type.

The data indicates the Core Ultra 5 336H sits in a competitive band where the top four rivals are all within 1% of its average score. The delta values range from -0.2% (Core i7-13700HX ahead) to +0.8% (Core Ultra 5 336H ahead of the Ryzen AI 7 350). This is a tightly grouped cluster of processors with no clear dominant leader.

Where Each One Wins

The Core Ultra 5 336H wins in every measurable performance category available in the database. Its 16-core configuration with 18 MB of L3 cache and a 3 nm process delivers Cinebench R23 multi-core performance of 23991, a figure that the Core 3 100UL cannot match because it has no recorded benchmarks. The newer chip also wins on platform features: PCIe Gen 5 with 12 lanes versus Gen 4 with 8 lanes, and LPDDR5X memory support that the older chip lacks.

The Core 3 100UL wins on platform compatibility and power draw. It uses Intel Socket 1700, a desktop socket that allows for system upgrades without replacing the motherboard. Its TDP is 15 W compared to the Core Ultra 5 336H's 25 W, a 10 W difference that matters in compact desktop builds or systems with limited cooling. The Core 3 100UL also supports DDR4, which can be a cost advantage for builders using existing DDR4 memory, and its 4.50 GHz boost clock is only 0.10 GHz below the newer chip's 4.60 GHz.

The Core Ultra 5 336H's PassMark results show particular strength in data compression (280340) and integer math (62070). Its floating point math score of 82415 indicates solid number-crunching ability. The physics score of 2682 and random string sorting score of 34402 round out a profile that favors mixed workloads. The data compression score is especially high relative to other subtests, suggesting strong memory subsystem performance, likely aided by the 18 MB L3 cache and 115.2 GB/s memory bandwidth.

The Core 3 100UL has no benchmark data to establish specific strengths, so its only documented advantages are the desktop socket, lower TDP, DDR4 support, and the 50th percentile ranking, which is far below the Core Ultra 5 336H's 84th percentile.

The specification table shows two processors separated by a full architectural generation. The Core Ultra 5 336H has 10 more cores, 8 more threads, a higher base clock, a higher boost clock, a higher TDP, double the L3 cache per core, a newer PCIe generation, and a faster memory standard. The Core 3 100UL's only specification advantages are the desktop Socket 1700 platform, DDR4 support, and a lower 15 W TDP. The 3 nm process node of the Core Ultra 5 336H versus the 10 nm node of the Core 3 100UL represents the clearest generational gap, and the benchmark data confirms that the newer chip delivers on that architectural promise.
