AMD Ryzen 3 3100U vs Intel Core Ultra 5 336H Comparison

# The Verdict

The Intel Core Ultra 5 336H is the dominant processor in every measured benchmark category. The database records 11 wins for the Intel part and zero for the AMD Ryzen 3 3100U. The Intel chip delivers a single-thread score of 4013 compared to 1592 for the AMD, a gap of 60.3 percent. In multithreaded work, the Intel part scores 28545 versus 3348, a difference of 88.3 percent. The average benchmark score confirms the scale of separation: 34485 for the Intel Core Ultra 5 336H against 6247 for the AMD Ryzen 3 3100U.

The AMD Ryzen 3 3100U sits at the 62nd percentile of all CPUs in the database. Its nearest rivals include the AMD Ryzen Threadripper 1950X with an average score of 6231 (0.3 percent ahead), the AMD EPYC 7272 at 6186 (1 percent ahead), and the Intel Core i9-7940X at 6147 (1.6 percent behind). This places the Ryzen 3 3100U in the mid-range of recorded mobile processors, capable for light workloads but not competitive with modern high-core-count designs.

The Intel Core Ultra 5 336H reaches the 84th percentile. Its nearest rivals include the Intel Core i7-13700HX at 34554 (0.2 percent ahead), the Intel Core i5-13450HX at 34333 (0.4 percent behind), the AMD Ryzen 7 3700X at 34260 (0.7 percent behind), and the AMD Ryzen AI 7 350 at 34222 (0.8 percent behind). These deltas show the Intel part performing essentially on par with several established desktop and mobile processors from recent generations.

The verdict is straightforward: the Intel Core Ultra 5 336H is the processor to choose for any workload where performance matters. The AMD Ryzen 3 3100U remains usable for basic tasks, but the recorded data offers no scenario where it wins against the Intel part in any measured test. The AMD chip's only practical advantage is its lower 15 W TDP versus 25 W for the Intel chip, which may matter in fanless or ultra-low-power designs, but even that comes with a substantial performance penalty.

Its codename is Picasso, and it belongs to the Ryzen 3 generation. The process node is 12 nm, fabricated by GlobalFoundries. The die measures 210 mm² and contains 4,940 million transistors.

The Intel Core Ultra 5 336H uses the Panther Lake architecture with the Panther Lake codename, belonging to the Core Ultra Series 3 generation. It is fabricated on a 3 nm process at Intel. The database does not list transistor count or die size for this part, which indicates a newer and more integrated design where such details are not yet public.

The cache structures differ significantly. The AMD chip provides 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel chip provides 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The larger per-core L1 and L2 caches on the Intel part, combined with 4.5 times more L3 cache, contribute to its substantial performance advantage in memory-intensive workloads.

The memory architectures also differ. The AMD Ryzen 3 3100U supports DDR4 memory on a dual-channel bus with a recorded bandwidth of 38.4 GB/s. The Intel Core Ultra 5 336H supports DDR5 and LPDDR5X memory on a dual-channel bus with a recorded bandwidth of 115.2 GB/s, which is three times higher. Neither processor supports ECC memory.

PCIe connectivity shows a generational leap. The AMD part uses PCIe Gen 3. The Intel part uses PCIe Gen 5 with 12 lanes for the CPU. This affects potential bandwidth for discrete GPUs and NVMe storage, though the database does not include specific PCIe throughput benchmarks.

These positions confirm that each processor competes in a different performance class.

# Where Each One Wins

The Intel Core Ultra 5 336H wins every recorded workload category. For users running multithreaded applications such as video encoding, 3D rendering, scientific computation, or data compression, the Intel part delivers scores that are 85 to 94 percent higher than the AMD chip across all tested workloads. Its 16 cores and 16 threads provide substantial parallel throughput, and the 18 MB of shared L3 cache supports data-heavy tasks.

For single-threaded responsiveness, the Intel chip still leads by 60.3 percent. Applications that rely on one or two cores, such as web browsing, office productivity, and light coding, will feel noticeably faster on the Intel Core Ultra 5 336H. The boost clock of 4.60 GHz is the highest recorded among the two parts.

The AMD Ryzen 3 3100U has no benchmark wins in the database. Its only differentiating factor is the lower 15 W TDP, which is 10 W lower than the Intel part's 25 W rating. For systems where thermal envelope is the primary constraint, such as compact ultrabooks or passively cooled designs, the AMD chip may be the only option that fits. However, the recorded data shows that any workload run on the AMD chip will complete with significantly lower performance.

The Intel Core Ultra 5 336H also offers newer memory support with DDR5 and LPDDR5X, a 3 nm process, PCIe Gen 5 connectivity, and a higher memory bandwidth of 115.2 GB/s. These factors contribute to its position at the 84th percentile of all CPUs. The AMD Ryzen 3 3100U, at the 62nd percentile, remains a functional entry-level mobile processor, but the database shows no scenario where it outperforms the Intel part.
