Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 8400F uses Zen 4 architecture with the Phoenix codename, built on a 4 nm process at TSMC. It packs 25,000 million transistors into a 178 mm² die. The Intel Core i7-14701E uses Raptor Lake architecture with the Raptor Lake-R codename, manufactured on a 10 nm process at Intel's own foundry. Its die measures 257 mm².

Core and thread counts differ substantially. AMD provides 6 cores and 12 threads, while Intel provides 8 cores and 16 threads. The cache hierarchy also diverges. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel uses 80 KB L1 per core, 2 MB L2 per core, and a larger 33 MB shared L3.

Clock speeds tell a contrasting story. AMD's base clock runs at 4.20 GHz with a boost of 4.70 GHz. Intel's base clock is lower at 2.60 GHz, but its boost reaches 5.40 GHz. Both parts share a 65 W TDP, though the underlying power behavior differs given the architectural choices.

Memory support separates the two. AMD supports only DDR5 with dual-channel configuration, delivering 83.2 GB/s bandwidth. Intel supports both DDR4 and DDR5 in dual-channel mode, though the database records no specific bandwidth figure for this part. ECC memory support is present on Intel but absent on AMD.

PCIe connectivity differs. AMD provides Gen 4 with 20 lanes (CPU only). Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics are absent on AMD, while Intel includes UHD Graphics 770.

Production status for both is Active. AMD released on 2024-03-31, and Intel on 2024-06-30. AMD's multiplier is unlocked, Intel's is locked. Both are desktop parts, with AMD on Socket AM5 and Intel on Socket 1700.

The Verdict

The recorded data supports a straightforward choice based on workload type. The Intel Core i7-14701E delivers superior performance in the majority of tested scenarios, including all Cinebench versions, PassMark multithread, single-thread, integer math, floating point math, physics, and prime number finding. Its 83rd percentile ranking versus AMD's 77th percentile confirms the overall performance advantage.

The AMD Ryzen 5 8400F wins in data compression, data encryption, extended instructions, and random string sorting. These are specific tasks where the Zen 4 architecture demonstrates strength despite the lower core count. The 12% and 19.7% margins in encryption and extended instructions respectively are notable, but they represent a narrow slice of the benchmark suite.

For users running Cinebench-based workloads, rendering, or general multithreaded applications, the Intel part is the clear choice based on the consistent 6.1% multicore advantage and the 14.4% single-thread lead. The physics test's 44.5% gap and the prime number test's 49.4% gap show particularly strong Intel performance in compute-heavy scenarios.

The AMD part serves a different purpose. Its wins in encryption and extended instructions suggest suitability for security-related or specialized instruction workloads. The data compression win, while small at 1.8%, still indicates competitive performance in that specific area. The random string sorting advantage of 18.7% points to strength in sorting algorithms.

Where Each One Wins

The Intel Core i7-14701E wins in all rendering and computational throughput tests. Cinebench R15, R20, and R23 multicore and single-core results all favor Intel by approximately 6%. PassMark multithread and single-thread tests favor Intel by 6.6% and 14.4% respectively. Integer math, floating point math, physics, and prime number finding all show Intel with margins ranging from 9% to 49.4%. These results indicate Intel's strength in general purpose computing, simulation, and number-crunching workloads.

The AMD Ryzen 5 8400F wins in data compression by 1.8%, data encryption by 12%, extended instructions by 19.7%, and random string sorting by 18.7%. These wins point to AMD's efficiency in data transformation tasks, cryptographic operations, and sorting algorithms. The margins in encryption and extended instructions are substantial, suggesting architectural advantages in those specific instruction paths.

The overall score distribution favors Intel for most users. With 13 wins against AMD's 4, and the average benchmark score gap of 8201 points, the Intel part delivers more consistent performance across the tested suite. However, the AMD part's specialized wins should not be dismissed. For workloads that match its strengths, the AMD Ryzen 5 8400F provides competitive or superior results, particularly in encryption and extended instruction tasks where it leads by double-digit percentages.

The choice depends on the primary workload. Intel suits mixed or compute-heavy usage patterns. AMD suits data-oriented tasks with its specific wins in compression, encryption, and sorting. Both parts operate at 65 W TDP, so power consumption does not differentiate them in the recorded data.
