The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 5 336H is the stronger processor for rendering, physics simulation, encryption, and most math workloads. Its Cinebench R23 multi-core score of 23991 is more than double the AMD chip's 11461, and its 84th percentile ranking puts it ahead of the AMD part's 81st percentile placement.

The AMD Ryzen AI 7 345 should be chosen when integer math throughput is the priority, as it leads by 2.3% in PassMark integer math. It also runs at a 28 W TDP versus Intel's 25 W, and it uses a 4 nm process from TSMC, while Intel uses a 3 nm process from its own foundry. The AMD part has 6 cores and 12 threads, compared to Intel's 16 cores and 16 threads, which explains much of the multi-core deficit.

For buyers prioritizing raw performance across a broad range of tasks, the Intel Core Ultra 5 336H is the pick. For workloads focused narrowly on integer calculations, the AMD Ryzen AI 7 345 holds a small but measurable edge. The Intel chip also offers a larger L3 cache, 18 MB shared versus AMD's 4 MB, and higher memory bandwidth at 115.2 GB/s versus 89.6 GB/s.

Specification Differences

The two processors differ substantially in core configuration. The AMD Ryzen AI 7 345 has 6 cores and 12 threads, while the Intel Core Ultra 5 336H has 16 cores and 16 threads. Base clocks are close, with AMD at 2.00 GHz and Intel at 1.90 GHz, but both boost to 4.60 GHz.

TDP ratings differ slightly, with AMD at 28 W and Intel at 25 W. The AMD chip uses the AMD Socket FP8, while Intel uses the Intel BGA 2540 socket. PCIe support also differs, with AMD offering Gen 4 across 14 lanes and Intel offering Gen 5 across 12 lanes.

Memory bandwidth favors Intel, with 115.2 GB/s versus AMD's 89.6 GB/s. Both support DDR5 and LPDDR5X memory in dual-channel configuration, and neither supports ECC memory. The integrated graphics differ as well, with AMD using the Radeon 840M and Intel using the Intel Xe3 Graphics.

The AMD part has a part number of 100-000002122, while the Intel part number is SA4RD. Release dates differ, with AMD's processor released on 2025-01-14 and Intel's on 2026-01-04.

Architecture Differences

The AMD Ryzen AI 7 345 is based on the Krackan Point codename and belongs to the Ryzen AI 300 generation, which uses a mix of Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process by TSMC. The cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3.

The Intel Core Ultra 5 336H uses the Panther Lake architecture, also known as Panther Lake-H, and is part of the Core Ultra Series 3. It is manufactured on a 3 nm process by Intel's own foundry. The cache configuration is larger, with 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3.

These architectural differences explain the benchmark gaps. Intel's larger L3 cache and higher memory bandwidth contribute to its strong performance in data compression and encryption tests. The 16-core configuration, even without hyperthreading, gives Intel a massive advantage in multi-threaded workloads like Cinebench R23 multi-core. AMD's hybrid Zen 5 and Zen 5c design, with fewer cores and threads, cannot match that throughput despite the efficiency of the 4 nm process.

Where Each One Wins

The Intel Core Ultra 5 336H wins in 14 of the 15 recorded benchmarks, making it the dominant choice for multi-threaded rendering, physics simulation, encryption, floating-point math, and data compression. Its Cinebench R23 multi-core score of 23991 is the standout result, and its PassMark physics score of 2682 is more than double the AMD chip's 1089. For users running CPU-intensive productivity tasks, video encoding, or 3D rendering, the Intel part is clearly superior.

The AMD Ryzen AI 7 345 wins only in PassMark integer math, with a score of 63475 against Intel's 62070. This narrow 2.3% margin suggests that integer-heavy code, such as certain database operations or compression algorithms that rely on integer arithmetic, may run slightly better on the AMD chip. The AMD part also carries a lower core count, which may appeal to workloads that favor fewer, higher-clocked cores, though the benchmark data does not show a single-thread win for AMD.

The Intel chip's 84th percentile ranking and average score of 34485 place it among stronger desktop-class processors like the Intel Core i7-13700HX and AMD Ryzen 7 3700X. The AMD Ryzen AI 7 345, with its 81st percentile and average score of 29461, sits closer to the AMD Ryzen 7 3800X and Intel Core i5-13500HX. The data makes the separation clear: the Intel Core Ultra 5 336H is the higher-performing processor in nearly every measurable category.
