Head-to-Head Benchmarks

The Intel Core Ultra 5 336H dominates the head-to-head comparison, winning 11 of 15 recorded benchmarks. The AMD Ryzen 7 PRO 8840HS secures 4 wins. The most decisive Intel victory comes in Cinebench R23 single-core, where it scores 3387 against AMD's 1724, a 49.1% advantage. This is the largest performance gap in the entire comparison. The Intel part also leads Cinebench R23 multi-core by 38.4%, scoring 23991 versus 14784.

Intel's other major wins include PassMark find prime numbers (299 vs 84, a 71.9% lead), PassMark physics (2682 vs 1351, a 49.6% lead), and PassMark floating point math (82415 vs 55739, a 32.4% lead). These results indicate a substantial advantage in compute-heavy and physics-based workloads. The Intel chip also wins PassMark single-thread (4013 vs 3692, an 8% lead), PassMark multithread (28545 vs 26646, a 6.7% lead), PassMark data encryption (21291 vs 18838, an 11.5% lead), and PassMark extended instructions (24542 vs 22298, a 9.1% lead). Cinebench R15 single-core also favors Intel, 341 vs 271.5, a 20.4% margin.

AMD's largest win comes in PassMark integer math, where it scores 93342 against Intel's 62070, a 50.4% advantage. This is a standout result for the Ryzen part. AMD also leads PassMark data compression (311199 vs 280340, an 11% lead) and PassMark random string sorting (37922 vs 34402, a 10.2% lead). The only Cinebench test AMD wins is R15 multi-core, where it edges out Intel 2458 vs 2418, a narrow 1.7% margin.

The overall average benchmark scores reflect Intel's broader advantage: the Core Ultra 5 336H averages 34485 across all recorded tests, while the Ryzen 7 PRO 8840HS averages 39603. However, the percentile rankings tell a slightly different story, with AMD at the 87th percentile and Intel at the 84th percentile among all CPUs in the database. This suggests AMD's wins are concentrated in specific workloads that heavily influence its average score, while Intel's wins are more distributed.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 7 PRO 8840HS is built on TSMC's 4 nm process with Zen 4 architecture, codenamed Hawk Point. It belongs to the 8000 series and uses AMD Socket FP7. The Intel Core Ultra 5 336H uses Intel's 3 nm process with Panther Lake architecture, part of the Core Ultra Series 3 and using Intel BGA 2540.

Core counts differ significantly. The AMD chip has 8 cores and 16 threads, while the Intel chip has 16 cores and 16 threads. This means Intel does not use simultaneous multithreading, whereas AMD doubles its thread count. The Intel design instead relies on more physical cores. Clock speeds favor AMD: it runs at 3.30 GHz base and 5.10 GHz boost, while Intel runs at 1.90 GHz base and 4.60 GHz boost. The AMD chip reaches a higher boost clock despite its lower thread count.

Cache hierarchies also differ. AMD provides 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel provides 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. Intel's larger L3 cache (18 MB vs 16 MB) and larger per-core L1 and L2 caches contribute to its single-thread and multi-thread performance lead.

Process node and transistor density vary. Intel uses a 3 nm node, AMD uses 4 nm. The database records AMD's transistor count at 25,000 million with a die size of 178 mm². Intel's transistor count and die size are not recorded in the data. Power targets are close: AMD's TDP is 28 watts, Intel's is 25 watts.

Memory support differs. AMD supports DDR5 with dual-channel memory and 89.6 GB/s bandwidth, plus ECC memory support. Intel supports DDR5 and LPDDR5X with dual-channel memory and 115.2 GB/s bandwidth, without ECC support. Intel's higher memory bandwidth (115.2 GB/s vs 89.6 GB/s) may contribute to its performance in memory-sensitive tests. PCIe capabilities also differ: AMD uses Gen 4 with 20 lanes, Intel uses Gen 5 with 12 lanes. Integrated graphics differ as well: AMD uses Radeon 780M, Intel uses Intel Xe3 Graphics.

Where Each One Wins

The Intel Core Ultra 5 336H is the stronger choice for compute-intensive and physics-based workloads. Its wins in PassMark physics (2682 vs 1351) and PassMark floating point math (82415 vs 55739) indicate a clear edge in scientific computing, simulation, and rendering tasks. The Cinebench R23 results (multi-core 23991 vs 14784, single-core 3387 vs 1724) reinforce this: Intel delivers far better performance in both multi-threaded rendering and single-threaded tasks. The PassMark find prime numbers result (299 vs 84) shows a massive advantage in integer-heavy algorithmic workloads, and PassMark data encryption (21291 vs 18838) points to stronger cryptographic processing.

The AMD Ryzen 7 PRO 8840HS wins in specific data-processing tasks. Its PassMark integer math score (93342 vs 62070) is the largest win of any test in either direction. PassMark data compression (311199 vs 280340) and PassMark random string sorting (37922 vs 34402) show AMD handles data manipulation and sorting more efficiently. The Cinebench R15 multi-core result (2458 vs 2418) gives AMD a narrow edge in that specific legacy render test, though Intel reverses this in Cinebench R23.

In practical terms, users running heavy parallel compute, rendering, encryption, or physics simulations should favor Intel. Users handling large data compression, integer arithmetic, or string sorting workloads should favor AMD. The Intel chip also wins the overall multithread test (28545 vs 26646) and single-thread test (4013 vs 3692), meaning it holds the general-purpose performance advantage across most tasks.

The Verdict

The benchmark data clearly favors the Intel Core Ultra 5 336H for most workloads. It wins 11 of 15 head-to-head tests, including all Cinebench R23 and R15 single-core tests, Cinebench R23 multi-core, PassMark physics, floating point math, find prime numbers, data encryption, extended instructions, multithread, and single-thread. Its largest margins come in Cinebench R23 single-core (49.1% ahead) and PassMark find prime numbers (71.9% ahead). Users prioritizing rendering, physics, encryption, or general single-threaded responsiveness should choose Intel.

The AMD Ryzen 7 PRO 8840HS retains a specific niche. Its 50.4% lead in PassMark integer math is the single largest delta in the comparison, and it also wins data compression and random string sorting by double-digit margins. For workloads dominated by integer arithmetic or data compression, AMD delivers better results. AMD also holds the 87th percentile versus Intel's 84th, meaning its overall average score (39603 vs 34485) ranks higher despite losing more individual tests.

The choice depends on workload type. Intel is the broader performer, winning across rendering, physics, encryption, and general compute. AMD is the specialist, winning in data compression and integer-heavy processing. The Intel chip also provides higher memory bandwidth (115.2 GB/s vs 89.6 GB/s) and a newer process node (3 nm vs 4 nm), while AMD offers ECC memory support and a higher boost clock (5.10 GHz vs 4.60 GHz). The recorded data indicates Intel is the stronger default option, with AMD as the targeted pick for specific data-processing tasks.
