Floating-point math shows a 46.3% gap, with the Ultra 5 245 at 120,548 and the Ultra 5 336H at 82,415. Data compression also leans heavily toward the desktop chip: 400,942 versus 280,340, a 43% edge. Random string sorting follows at 42.8%, and data encryption at 42%. Extended instructions favor the Ultra 5 245 by 35.7%, with scores of 33,304 and 24,542.

Cinebench results are uniformly in favor of the Ultra 5 245, with the desktop processor holding a 37.2% lead across Cinebench R15 multi-core, R15 single-core, R20 multi-core, and R23 multi-core. The R20 single-core test shows a 37.3% margin, the largest Cinebench gap in the dataset. The desktop part reaches 3,318 in Cinebench R15 multi-core versus 2,418 for the mobile chip, and 32,924 versus 23,991 in Cinebench R23 multi-core. Single-thread Cinebench scores follow the same pattern: 468 versus 341 in R15, 1,952 versus 1,422 in R20, and 4,648 versus 3,387 in R23.

The narrowest win for the Ultra 5 245 comes in PassMark single-thread testing, where it scores 4,394 against 4,013 for the Ultra 5 336H, a 9.5% margin. Prime number finding shows a 22.1% gap (365 versus 299), and PassMark multi-thread favors the desktop chip by 35.6% (38,706 versus 28,545).

The sole benchmark win for the Ultra 5 336H is PassMark physics, where it scores 2,682 against 2,569 for the Ultra 5 245, a 4.2% advantage. This is the only recorded test where the mobile processor outpaces its desktop counterpart.

Where Each One Wins

The benchmark distribution splits cleanly by workload type. The Intel Core Ultra 5 245 dominates compute-heavy parallel workloads. Its Cinebench multi-core scores, PassMark multi-thread score, integer math, floating-point math, and data compression results all point to a processor built for sustained throughput in rendering, scientific computing, and content creation tasks. The 37.2% Cinebench R23 multi-core lead and the 46.9% integer math advantage are the clearest signals: workloads that scale across cores and instructions will consistently favor the desktop chip.

The Ultra 5 245 also owns the single-thread category. Every single-core benchmark in the dataset shows the desktop processor ahead, from the 37.2% Cinebench R15 single-core margin down to the 9.5% PassMark single-thread edge. This suggests responsiveness in lightly threaded applications, legacy software, and general desktop use also falls to the Ultra 5 245.

The Intel Core Ultra 5 336H has a much narrower claim. Its only win is PassMark physics at 2,682 versus 2,569, a 4.2% edge. Physics simulation in PassMark tends to reflect short-burst integer and floating-point operations with moderate thread counts, and the mobile chip's 16 cores and 16 threads may help in that specific scenario. But this single result does not translate into broader success. The Ultra 5 336H trails in every other category, including PassMark multi-thread (28,545 versus 38,706) and Cinebench R23 multi-core (23,991 versus 32,924). The data indicates the 336H is competitive only in a narrow physics-related workload, while the 245 holds the advantage across rendering, math, compression, encryption, and single-thread performance.

Architecture Differences

The two processors come from different Intel series and use different underlying designs. The Intel Core Ultra 5 245 belongs to Core Ultra Series 2, built on the Arrow Lake architecture with the Arrow Lake-S codename. It uses TSMC's 3 nm process node and contains 17,800 million transistors on a 243 mm² die. The Intel Core Ultra 5 336H belongs to Core Ultra Series 3, built on the Panther Lake architecture with the Panther Lake codename. It also uses a 3 nm process node, but the foundry is Intel rather than TSMC. No transistor count or die size data is recorded for the 336H.

Core and thread counts differ. The Ultra 5 245 has 14 cores and 14 threads, while the Ultra 5 336H has 16 cores and 16 threads. Neither processor supports Hyper-Threading, so thread counts equal core counts in both cases. The desktop chip has a higher base clock of 3.50 GHz and a higher boost clock of 5.10 GHz, compared to 1.90 GHz base and 4.60 GHz boost for the mobile part. The desktop processor carries a 65 W TDP, while the mobile processor is rated at 25 W.

Cache configurations also differ. Both chips use 192 KB of L1 cache per core. The Ultra 5 245 has 3 MB of L2 cache per core and 24 MB of shared L3 cache. The Ultra 5 336H has 2.5 MB of L2 per core and 18 MB of shared L3. The desktop part's larger cache hierarchy aligns with its higher sustained performance in the benchmark data.

Memory support separates the two as well. The Ultra 5 245 supports DDR5 over a dual-channel bus with 102.4 GB/s bandwidth and includes ECC memory support. The Ultra 5 336H supports both DDR5 and LPDDR5X over a dual-channel bus with 115.2 GB/s bandwidth, but does not support ECC memory. The mobile chip's higher memory bandwidth reflects its LPDDR5X support, which is typical for mobile platforms.

PCIe connectivity differs. The Ultra 5 245 provides Gen 5 with 20 CPU lanes, while the Ultra 5 336H provides Gen 5 with 12 CPU lanes. Integrated graphics also differ: the Ultra 5 245 uses Arc Xe-LPG Graphics with 64 execution units, while the Ultra 5 336H uses Intel Xe3 Graphics. The desktop part uses Intel Socket 1851, while the mobile part uses Intel BGA 2540. The Ultra 5 245 was released on January 6, 2025, and the Ultra 5 336H on January 4, 2026. Both are marked as Active in production status, and neither has an unlocked multiplier.

The Verdict

The benchmark data presents a clear hierarchy. The Intel Core Ultra 5 245 wins 16 of 17 head-to-head comparisons, holds a 90th percentile ranking among all CPUs, and averages 48,995 in benchmark scores. The Intel Core Ultra 5 336H wins only PassMark physics, ranks at the 84th percentile, and averages 34,485. Any workload built around Cinebench rendering, PassMark math, data compression, encryption, or single-thread responsiveness will favor the Ultra 5 245 by margins ranging from 9.5% to 46.9%.

The Ultra 5 336H is not without purpose. Its 16 cores and 16 threads, 25 W TDP, and support for LPDDR5X memory position it for mobile systems where power efficiency matters. Its memory bandwidth of 115.2 GB/s is higher than the desktop part's 102.4 GB/s, and its physics benchmark win shows it can handle specific short-burst workloads. But the recorded data does not show it outperforming the Ultra 5 245 in any general-purpose compute category.

The Ultra 5 245 is the stronger processor for desktop builds, with a 65 W TDP, higher clock speeds, larger L3 cache, more PCIe lanes, and ECC memory support. The Ultra 5 336H serves the mobile segment, where its lower TDP and LPDDR5X support are relevant. The data supports choosing the Ultra 5 245 for desktop-oriented workloads that prioritize throughput and single-thread speed, while the Ultra 5 336H fits mobile systems that need 16 cores within a 25 W envelope. The launch MSRP for the Ultra 5 245 is $270; no launch MSRP is recorded for the Ultra 5 336H.
