AMD Ryzen 5 40 vs Intel Core Ultra 5 336H Comparison

AMD Ryzen 5 40 and Intel Core Ultra 5 336H are both mobile processors, but the recorded benchmark data shows a decisive performance gap. The Intel part wins all 15 head-to-head comparisons in the database, with the AMD processor trailing by double-digit percentages in every single test. The Ryzen 5 40 is a low-power Zen 2 design, while the Core Ultra 5 336H is a larger Panther Lake chip with more cores and a newer process node. This analysis walks through the measured scores, architectural differences, and the specific workloads where each processor holds an advantage.

Head-to-Head Benchmarks

The Intel Core Ultra 5 336H dominates the AMD Ryzen 5 40 across every recorded benchmark. The largest delta appears in the PassMark find prime numbers test, where Intel scores 299 versus AMD's 20, a 93.3% difference. This is a prime-number computation workload that heavily favors the Intel architecture's higher core count and clock speed. Similarly, in PassMark floating point math, Intel scores 82415 against AMD's 15194, a delta of 81.6%. The physics test shows an 83.9% gap, with Intel at 2682 and AMD at 432. These three tests highlight the Intel part's substantial advantage in compute-heavy, multi-threaded workloads.

Cinebench results follow the same pattern. In Cinebench R23 multi-core, Intel scores 23991 while AMD scores 4841, a 79.8% delta. The single-core R23 test shows Intel at 3387 versus AMD's 1150, a 66% gap. Cinebench R15 multi-core has Intel at 2418 and AMD at 790, a 67.3% difference, while single-core R15 shows Intel at 341 and AMD at 165.5, a 51.5% gap. The database also records a Cinebench R20 result for Intel only (multi-core 10076, single-core 1422), which further confirms its multi-threaded strength, though no comparable AMD R20 score exists in the dataset.

PassMark integer math shows Intel at 62070 versus AMD's 31598, a 49.1% delta. Data compression scores Intel at 280340 and AMD at 141533, a 49.5% gap. Data encryption has Intel at 21291 and AMD at 6646, a 68.8% difference. Extended instructions show Intel at 24542 and AMD at 6437, a 73.8% gap. Random string sorting has Intel at 34402 and AMD at 15124, a 56% difference. PassMark multi-thread scores Intel at 28545 and AMD at 9341, a 67.3% gap. Single-thread PassMark shows Intel at 4013 and AMD at 2477, a 38.3% delta.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 40 uses Zen 2 architecture on a 6 nm process from TSMC, with a die size of 100 mm². It has 4 cores and 8 threads, with 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The processor runs on AMD Socket FT6 and supports LPDDR5 memory in a dual-channel configuration. Its integrated graphics are the Radeon 610M. The base clock is 2.80 GHz with a boost clock of 4.30 GHz, and the thermal design power is 15 watts.

The Intel Core Ultra 5 336H uses Panther Lake architecture on a 3 nm process from Intel. It has 16 cores and 16 threads, with 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The processor runs on Intel BGA 2540 and supports DDR5 and LPDDR5X memory in a dual-channel configuration. Its integrated graphics are Intel Xe3 Graphics. The base clock is 1.90 GHz with a boost clock of 4.60 GHz, and the thermal design power is 25 watts.

The process node difference is significant: 3 nm versus 6 nm, which contributes to the Intel part's higher transistor density and efficiency per clock. The Intel chip also has 4.5 times more L3 cache (18 MB versus 4 MB) and 4 times more cores (16 versus 4). The memory bandwidth is 31% higher on Intel (115.2 GB/s versus 88.0 GB/s). PCIe support differs as well: Intel uses Gen 5 with 12 lanes, while AMD uses Gen 3 with 4 lanes.

Neither processor supports ECC memory, and neither has an unlocked multiplier. The AMD part lists a part number of "unknown" and has no launch MSRP in the database, while the Intel part has the part number SA4RD and also no launch MSRP. Both are marked as Active in production status and target the Mobile market segment.

The Verdict

The recorded data leaves no ambiguity: the Intel Core Ultra 5 336H is the stronger processor in every benchmark category. Its 16-core configuration, larger cache hierarchy, newer process node, and higher boost clock deliver consistent wins across synthetic workloads. The AMD Ryzen 5 40, with 4 cores and a 15-watt TDP, is a lower-power design that cannot match the Intel part's throughput. The percentile rankings confirm this: Intel sits at the 84th percentile of all CPUs, while AMD sits at the 70th percentile.

For workloads that demand multi-threaded performance, such as rendering, data compression, or physics simulations, Intel holds an overwhelming advantage. The Cinebench R23 multi-core score of 23991 versus 4841 represents a 79.8% gap that no software optimization can close. For single-threaded tasks, Intel still leads by at least 38.3%, making it the better choice even for lightly threaded applications.

The AMD Ryzen 5 40 is not without merit. Its 15-watt TDP and 6 nm process suggest it targets fanless or ultra-portable designs where power efficiency matters more than raw performance. The 4-core configuration with 8 threads provides adequate processing for basic productivity tasks, and the Radeon 610M integrated graphics handle display output without a discrete GPU. However, the database shows no benchmark where AMD wins, so any performance-sensitive use case favors Intel.

Specification Differences

The two processors differ across nearly every specification field in the database. The AMD Ryzen 5 40 has 4 cores and 8 threads, while the Intel Core Ultra 5 336H has 16 cores and 16 threads. Base clocks are 2.80 GHz for AMD and 1.90 GHz for Intel, but boost clocks are 4.30 GHz and 4.60 GHz respectively. Thermal design power is 15 watts for AMD and 25 watts for Intel.

Cache configurations diverge sharply. AMD has 64 KB L1 per core, 512 KB L2 per core, and 4 MB shared L3. Intel has 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. Memory support is LPDDR5 for AMD versus DDR5 and LPDDR5X for Intel. Memory bandwidth is 88.0 GB/s for AMD and 115.2 GB/s for Intel.

PCIe support is Gen 3 with 4 lanes for AMD versus Gen 5 with 12 lanes for Intel. Integrated graphics are Radeon 610M for AMD and Intel Xe3 Graphics for Intel. Process nodes are 6 nm (TSMC) for AMD and 3 nm (Intel) for Intel. Sockets are AMD Socket FT6 and Intel BGA 2540. Architecture is Zen 2 (Mendocino) for AMD and Panther Lake for Intel. The die size is 100 mm² for AMD and null in the database for Intel. Release dates are 2025-09-30 for AMD and 2026-01-04 for Intel. The Intel part has a part number SA4RD, while AMD's part number is unknown.

Where Each One Wins

The Intel Core Ultra 5 336H wins in every recorded benchmark, so the practical choice depends on the workload type. For multi-threaded tasks, Intel is the clear pick. The Cinebench R23 multi-core score of 23991 indicates strong rendering performance. PassMark multi-thread at 28545 supports heavy parallel workloads like video encoding or 3D modeling. Data compression at 280340 and integer math at 62070 show strength in database operations and scientific computing. Floating point math at 82415 and physics at 2682 confirm suitability for simulations and engineering tools.

For single-threaded tasks, Intel also leads, but by a smaller margin. PassMark single-thread at 4013 versus 2477, a 38.3% delta, is the closest contest in the dataset. Applications like web browsing, office suites, and light coding benefit from the higher boost clock and newer architecture. The extended instructions score of 24542 versus 6437 indicates that Intel handles modern SIMD workloads with substantially better efficiency.

The AMD Ryzen 5 40 does not win any benchmark, but its 15-watt TDP and 4-core design point to a specific role. The 6 nm process and 100 mm² die size suggest a compact, low-power package suitable for thin-and-light laptops or embedded systems. The Radeon 610M integrated GPU provides basic graphics output. The 70th percentile ranking means it outperforms 70% of all CPUs, which is respectable for a low-power part. However, the database contains no scenario where AMD outperforms Intel, so the Intel Core Ultra 5 336H is the superior choice for any performance-oriented mobile application.
