AMD Ryzen 5 7400F vs Intel Core Ultra 5 336H Comparison

The Verdict

The benchmark data separates these two processors into distinct use cases. The Intel Core Ultra 5 336H wins 14 of 17 head-to-head tests, while the AMD Ryzen 5 7400F takes only 3. The Intel part posts an average benchmark score of 34485 versus 32750 for the AMD, a gap that places the Ultra 5 336H at the 84th percentile of all CPUs compared to the 83rd percentile for the Ryzen 5 7400F. The Ryzen 5 7400F sits closest to the Intel Core i5-14600T (0.1% ahead) and the Intel Core Ultra 7 155H (0.2% ahead) in the database, while the Ultra 5 336H trades blows with the Intel Core i7-13700HX, coming in 0.2% behind it. Desktop builders with an AM5 platform should note that the Ryzen 5 7400F offers a 65 W TDP, an unlocked multiplier, and a $229 launch MSRP, but the data shows it trails the mobile Intel part in nearly every measured workload. The Ultra 5 336H is the stronger overall performer, but its BGA 2540 socket and 25 W TDP place it in laptops, not desktop towers.

Where Each One Wins

The AMD Ryzen 5 7400F claims victory in three specific workloads. It leads in PassMark data compression with a score of 289999 against 280340, a 3.4% margin. It dominates in PassMark integer math at 74745 versus 62070, a 20.4% advantage. It also edges out the Intel part in random string sorting at 35096 versus 34402, a 2% margin. These wins point to integer-heavy and compression-oriented tasks where the Zen 4 architecture's per-core efficiency shows through.

The Intel Core Ultra 5 336H wins everywhere else. Its Cinebench results are consistently about 9.3% ahead across R15, R20, and R23 in both single-core and multi-core tests. The largest Intel margins come in floating point math (82415 versus 45799, a 44.4% lead), physics (2682 versus 1660, a 38.1% lead), and prime number finding (299 versus 191, a 36.1% lead). Data encryption also favors Intel heavily at 21291 versus 16712, a 21.5% gap. The Ultra 5 336H delivers a 10.2% lead in PassMark multithread and an 8.1% lead in single-thread performance. The Intel part's 16 threads versus the AMD's 12 threads, combined with its newer Panther Lake architecture, explains the broad sweep in compute-heavy benchmarks.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7400F uses Zen 4 architecture on the Raphael codename, built on a 5 nm process at TSMC with 6,570 million transistors on a 71 mm² die. It has 6 cores and 12 threads with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The cache layout is 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. It supports DDR5 memory in dual-channel configuration with 83.2 GB/s of bandwidth and includes ECC memory support. The platform uses AMD Socket AM5 with PCIe Gen 5 across 24 CPU lanes. There is no integrated graphics, so a discrete GPU is mandatory. The multiplier is unlocked, which allows overclocking. It was released on 2025-01-08 with a part number of 100-000001845.

The Intel Core Ultra 5 336H uses Panther Lake architecture with the Panther Lake-H generation label, built on a 3 nm process at Intel. It has 16 cores and 16 threads with a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The cache layout differs substantially: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. Memory support includes both DDR5 and LPDDR5X in dual-channel configuration with 115.2 GB/s of bandwidth, but ECC memory is not supported. The socket is Intel BGA 2540, which is soldered for mobile use. PCIe Gen 5 is limited to 12 CPU lanes. Integrated graphics are present in the form of Intel Xe3 Graphics, so the chip can operate without a discrete GPU. The multiplier is locked. The release date is 2026-01-04 and the part number is SA4RD.

The process node difference is significant: 3 nm at Intel versus 5 nm at TSMC. The Intel part uses more cores (16 versus 6) and more threads (16 versus 12), but the AMD part has a much higher base clock (3.70 GHz versus 1.90 GHz) and a slightly higher boost clock (4.70 GHz versus 4.60 GHz). The TDP difference is stark: 25 W for Intel versus 65 W for AMD. The L3 cache favors AMD at 32 MB versus 18 MB, while Intel has larger per-core L1 and L2 allocations.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern. Across R15, R20, and R23, the Intel Core Ultra 5 336H beats the AMD Ryzen 5 7400F by 9.3% in multicore tests. The scores are 2418 versus 2193 in R15, 10076 versus 9141 in R20, and 23991 versus 21765 in R23. Single-core results follow the same trajectory: 341 versus 309 in R15 (9.4% lead), 1422 versus 1290 in R20 (9.3% lead), and 3387 versus 3072 in R23 (9.3% lead). This uniform margin across rendering workloads indicates a steady architectural advantage for the Panther Lake design rather than a workload-specific quirk.

The PassMark suite reveals where the AMD part fights back. Integer math is the AMD's strongest category: 74745 versus 62070, a 20.4% margin that is the largest AMD win in the entire comparison. Data compression also favors AMD at 289999 versus 280340, a 3.4% edge. Random string sorting goes to AMD at 35096 versus 34402, a 2% margin. These are the only three tests where the Ryzen 5 7400F comes out ahead, and they all involve integer or string manipulation rather than floating point or physics simulation.

The Intel part's largest wins are dramatic. Floating point math shows a 44.4% gap: 82415 versus 45799. Physics simulation gives Intel a 38.1% lead at 2682 versus 1660. Prime number finding favors Intel by 36.1% at 299 versus 191. Data encryption shows a 21.5% gap at 21291 versus 16712. Extended instructions go to Intel by 11.4% at 24542 versus 21747. The PassMark multithread score gives Intel a 10.2% win at 28545 versus 25645, and single-thread tests give Intel an 8.1% lead at 4013 versus 3689.

The overall average benchmark score confirms the trend: 34485 for the Intel part versus 32750 for the AMD part. The Intel Core Ultra 5 336H lands at the 84th percentile of all CPUs, one point above the Ryzen 5 7400F at the 83rd percentile. The nearest rivals in the database reinforce the positioning. The AMD part is effectively tied with the Intel Core i5-14600T (0.1% ahead), the Intel Core Ultra 7 155H (0.2% ahead), and the AMD Ryzen 7 PRO 6850H (0.2% behind). The Intel part sits 0.2% behind the Intel Core i7-13700HX, 0.4% ahead of the Intel Core i5-13450HX, 0.7% ahead of the AMD Ryzen 7 3700X, and 0.8% ahead of the AMD Ryzen AI 7 350.

Specification Differences

The core and thread counts differ substantially: the AMD Ryzen 5 7400F has 6 cores and 12 threads, while the Intel Core Ultra 5 336H has 16 cores and 16 threads. Clock speeds also differ: the AMD part runs at 3.70 GHz base and 4.70 GHz boost, while the Intel part runs at 1.90 GHz base and 4.60 GHz boost. TDP is a major split: 65 W for AMD versus 25 W for Intel.

The cache hierarchies are built differently. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. Intel uses 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. This gives AMD more L3 cache overall but Intel more per-core L1 and L2.

Memory support diverges on ECC and bandwidth. Both support dual-channel DDR5, but the Intel part also supports LPDDR5X. Memory bandwidth is higher on the Intel part at 115.2 GB/s versus 83.2 GB/s for AMD. ECC memory works on the AMD part but not on the Intel part.

The platform targets differ completely. The AMD Ryzen 5 7400F uses AMD Socket AM5, a desktop socket, with an unlocked multiplier and 24 PCIe Gen 5 lanes. The Intel Core Ultra 5 336H uses Intel BGA 2540, a soldered mobile socket, with a locked multiplier and 12 PCIe Gen 5 lanes. The AMD part has no integrated graphics, while the Intel part includes Intel Xe3 Graphics. The process nodes are 5 nm for AMD at TSMC versus 3 nm for Intel at its own foundry. The AMD part carries a $229 launch MSRP, while the Intel part has no recorded launch MSRP.
