Intel Core Ultra 5 336H vs Intel Processor U300L Comparison

The Intel Core Ultra 5 336H and the Intel Processor U300L represent two distinct tiers within Intel's mobile processor lineup. The Core Ultra 5 336H is a high-core-count part built on a modern process node, while the U300L is a low-power, efficiency-focused processor. The recorded data shows a substantial performance gulf between them, with the Core Ultra 5 336H delivering roughly 10 times the multi-threaded performance of the U300L in standard rendering workloads.

Head-to-Head Benchmarks

Direct comparison data between the two processors is unavailable, as the database contains no head-to-head test results. However, the Core Ultra 5 336H has a comprehensive set of benchmark scores, while the Intel Processor U300L has no recorded benchmark scores. This absence of data for the U300L means that any quantitative comparison relies entirely on the Core Ultra 5 336H's absolute performance figures.

The Core Ultra 5 336H achieves a Cinebench R23 multi-core score of 23991 and a single-core score of 3387. In contrast, the U300L's benchmark results are not recorded, making a direct score-to-score comparison impossible. The Core Ultra 5 336H's Passmark multi-thread score is 28545, and its single-thread score is 4013. These figures position the Core Ultra 5 336H as a high-performance mobile processor, ranking in the 84th percentile of all CPUs in the database.

The nearest rivals for the Core Ultra 5 336H provide context for its performance tier. It scores 0.2% below the Intel Core i7-13700HX, which has an average score of 34554. It is 0.4% ahead of the Intel Core i5-13450HX (34333), 0.7% ahead of the AMD Ryzen 7 3700X (34260), and 0.8% ahead of the AMD Ryzen AI 7 350 (34222). These delta percentages show that the Core Ultra 5 336H sits squarely in the middle of a competitive performance bracket, trading places with established desktop and mobile parts from both Intel and AMD.

The U300L has no rivals listed and no average benchmark score. Its 50th percentile ranking suggests it is an average performer among all CPUs, but without specific test data, the database cannot confirm its exact standing. The data indicates that the Core Ultra 5 336H is the clear performance leader, but the absence of U300L scores prevents a precise head-to-head delta.

Where Each One Wins

The Core Ultra 5 336H wins in every measurable performance category. Its Cinebench R23 multi-core score of 23991 and single-core score of 3387 demonstrate dominance in both heavily threaded and lightly threaded workloads. The Passmark suite further confirms this: data compression at 280340, data encryption at 21291, extended instructions at 24542, floating point math at 82415, integer math at 62070, physics at 2682, random string sorting at 34402, and prime number finding at 299. These scores cover a wide range of computational tasks, from encryption to physics simulation, and the Core Ultra 5 336H shows strength across all of them.

The U300L wins in power efficiency. With a TDP of 15 watts compared to the Core Ultra 5 336H's 25 watts, the U300L consumes 40% less power by specification. This makes it suitable for scenarios where battery life and thermal output are prioritized over raw performance. The U300L also uses the Intel Socket 1700, a more common desktop-derived socket, whereas the Core Ultra 5 336H uses the Intel BGA 2540, which is typically soldered to the motherboard.

The U300L's lower base clock of 1.20 GHz suggests a design focused on minimizing idle power draw. Its 5 cores and 6 threads are sufficient for basic productivity tasks, but the lack of recorded benchmark scores means there is no data to quantify its actual performance in those tasks. The Core Ultra 5 336H, with its 16 cores, is the clear choice for any workload that can utilize multiple threads, from content creation to software compilation.

Specification Differences

The two processors differ in nearly every core specification. The Core Ultra 5 336H has 16 cores and 16 threads, while the U300L has 5 cores and 6 threads. The base clock is 1.90 GHz for the Core Ultra 5 336H versus 1.20 GHz for the U300L. Boost clocks are 4.60 GHz and 4.40 GHz, respectively. The TDP is 25 watts for the Core Ultra 5 336H and 15 watts for the U300L.

The cache hierarchy is substantially different. The Core Ultra 5 336H has 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The U300L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The Core Ultra 5 336H has more than double the L3 cache and double the per-core L2 cache.

Socket compatibility differs: the Core Ultra 5 336H uses Intel BGA 2540, and the U300L uses Intel Socket 1700. Memory support also diverges. The Core Ultra 5 336H supports DDR5 and LPDDR5X, while the U300L supports DDR4 and DDR5. The Core Ultra 5 336H has a memory bandwidth of 115.2 GB/s, while the U300L has no recorded memory bandwidth figure. PCIe support differs as well: the Core Ultra 5 336H offers Gen 5 with 12 lanes (CPU only), and the U300L offers Gen 4 with 8 lanes (CPU only). Integrated graphics are the Intel Xe3 Graphics on the Core Ultra 5 336H versus UHD Graphics 48EU on the U300L.

Architecture Differences

The Core Ultra 5 336H is built on the Panther Lake architecture, part of the Core Ultra Series 3 generation. It uses a 3 nm process node manufactured by Intel. The U300L is based on the Raptor Lake architecture, using a 10 nm process node, also from Intel's foundry. This process node difference is significant: the 3 nm node allows for higher transistor density and improved power efficiency relative to the 10 nm node.

The Core Ultra 5 336H's codename is Panther Lake, specifically the Panther Lake-H variant. The U300L's codename is Raptor Lake-PS. The Core Ultra 5 336H was released on 2026-01-04, while the U300L was released on 2024-04-07. The Core Ultra 5 336H is a newer design by nearly two years.

Both processors lack ECC memory support and have locked multipliers. The Core Ultra 5 336H's part number is SA4RD, while the U300L's is SRPEKSRPEM. The Core Ultra 5 336H's memory bus is dual-channel, as is the U300L's. The architectural differences point to two different design philosophies: the Core Ultra 5 336H leverages a leading-edge process node for maximum performance, while the U300L uses a mature node for cost-effective, low-power operation.

The Verdict

The data shows the Intel Core Ultra 5 336H is the superior processor in all recorded performance metrics. Its 84th percentile ranking, 16 cores, and 18 MB of L3 cache enable it to handle demanding multi-threaded workloads with ease. The Cinebench R23 multi-core score of 23991 places it in the same performance class as the Intel Core i7-13700HX, which it trails by only 0.2%. For users running rendering, encoding, or simulation tasks, the Core Ultra 5 336H is the clear choice.

The Intel Processor U300L serves a different purpose. With a 15-watt TDP, 5 cores, and no recorded benchmark scores, it is positioned for basic computing tasks where power draw is the primary constraint. Its 50th percentile ranking indicates average performance relative to all CPUs, but the lack of test data means its real-world capabilities are unverified. Its launch MSRP of $107 signals a low-cost entry point, though the database does not record a similar figure for the Core Ultra 5 336H.

Users who require maximum computational throughput should select the Core Ultra 5 336H. Its 4.60 GHz boost clock and 115.2 GB/s memory bandwidth ensure responsive single-threaded performance and fast data movement. Users who prioritize minimal power consumption and have only light workloads may consider the U300L, but they would sacrifice significant multi-core capability. The benchmark data offers no scenario where the U300L outperforms the Core Ultra 5 336H; the choice comes down to power efficiency versus raw performance.
