AMD Ryzen 5 8400F vs Intel Core 5 221E Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall lead for the Intel Core 5 221E, which wins 16 of the 17 recorded head-to-head tests. The AMD Ryzen 5 8400F claims only a single victory. The scale of Intel's advantage varies substantially by workload, from narrow single-digit margins to near-parity in one test, to gaps of nearly half in others.

The largest Intel win comes in PassMark's find prime numbers test, where the Core 5 221E scores 173 against the Ryzen 5 8400F's 89, a 48.6% advantage. This test heavily rewards the Intel part's larger core count and higher boost clock. Floating point math shows a similar pattern: Intel scores 79,028 versus AMD's 46,217, a 41.5% gap. Integer math follows at 117,813 versus 74,021, a 37.2% difference. Physics simulation results favor Intel by 40.3%, with scores of 2,230 and 1,332 respectively.

The Cinebench suite tells a consistent story. In Cinebench R23 multicore, Intel scores 25,933 against AMD's 20,851, a 19.6% margin. The same 19.6% delta appears across every Cinebench test, both single-core and multi-core, including R15 and R20. Intel's single-core advantage in Cinebench R23 is 3,661 versus 2,943. This uniformity suggests a consistent architectural efficiency gap rather than workload-specific behavior.

PassMark multithread results show Intel ahead at 30,510 versus 24,389, a 20.1% difference. Data compression favors Intel by 11.1%, with scores of 324,285 and 288,158. Data encryption shows a 13.3% Intel edge, 19,205 versus 16,646. Random string sorting is closer at 8.2%, with Intel scoring 37,686 against AMD's 34,604. Single-thread tests in PassMark also favor Intel by 11.1%, 4,147 versus 3,685.

The lone AMD victory comes in PassMark extended instructions, where the Ryzen 5 8400F scores 22,175 against Intel's 18,216, a 21.7% advantage. This indicates the AMD part's instruction set extensions deliver measurable throughput in workloads that use them heavily. It is the only test where AMD's architecture overcomes Intel's core count and clock speed advantages.

Architecture Differences

The two processors take fundamentally different design approaches. The AMD Ryzen 5 8400F uses the Zen 4 architecture on a 4 nm TSMC process, codenamed Phoenix. It packs 6 cores and 12 threads. The Intel Core 5 221E uses the Bartlett Lake design on Intel's 10 nm process, offering 14 cores and 20 threads. Intel's process node is older, but the core count advantage is substantial: 14 versus 6 cores, and 20 versus 12 threads.

Clock speeds differ meaningfully. AMD's base clock is 4.20 GHz with a boost of 4.70 GHz. Intel's base clock is lower at 2.70 GHz, but its boost reaches 5.20 GHz. The Intel part's higher peak clock helps explain its single-thread wins in Cinebench and PassMark. AMD's higher base clock does not compensate in the recorded benchmarks.

Cache configurations also diverge. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel offers 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. Intel's larger L2 and L3 caches give it more on-die data capacity, which benefits workloads with repeated data access.

Memory support differs as well. AMD uses DDR5 only, with dual-channel access and 83.2 GB/s of bandwidth. Intel supports both DDR4 and DDR5, also dual-channel, with 89.6 GB/s of bandwidth. Intel's higher memory bandwidth and broader memory compatibility give it flexibility in system configuration. AMD's platform does not support ECC memory, while Intel's does.

PCIe connectivity contrasts sharply. AMD provides Gen 4 with 20 lanes from the CPU. Intel provides Gen 5 with 16 lanes. Intel's PCIe version is newer and offers higher per-lane bandwidth, though AMD has more total lanes. The Intel part also includes integrated UHD Graphics 730, while the AMD part has no integrated graphics, requiring a discrete GPU in all configurations.

The Intel die is larger at 257 mm² versus AMD's 178 mm². AMD's transistor count is recorded at 25,000 million; Intel's is not listed in the database. Both parts carry a 65 W TDP, so power draw at the socket level is identical, but the underlying silicon efficiency differs given the process node gap.

Where Each One Wins

The Intel Core 5 221E wins in nearly every measured category. It dominates multi-threaded productivity workloads, as shown by Cinebench R23 multicore and PassMark multithread scores. Its higher core count and boost clock make it the stronger choice for rendering, compilation, data processing, and any workload that scales across threads. The 41.5% lead in floating point math and 37.2% lead in integer math indicate strong number-crunching performance. The 40.3% physics advantage reinforces this for simulation-style tasks.

Intel also wins all single-thread tests in the database. The 11.1% PassMark single-thread edge and the 19.6% Cinebench single-core edge show that Intel's higher boost clock of 5.20 GHz delivers real performance in latency-sensitive tasks. Data compression, encryption, and random string sorting all favor Intel, making it the better option for archiving, database work, and file management.

The AMD Ryzen 5 8400F wins only in extended instructions. This specific test measures throughput of SIMD and other instruction set extensions. The 21.7% AMD advantage suggests that software which heavily uses AVX-512 or similar advanced instructions will run faster on the AMD part. This is a narrow but real niche for scientific computing, certain encryption algorithms, and media processing that explicitly uses these extensions.

For general desktop use, gaming, and everyday applications, the database shows Intel ahead in every recorded metric. The AMD part's single win does not offset the breadth of Intel's victories. Users with workloads that specifically leverage extended instruction sets would see AMD benefit, but that is the only scenario where the data supports choosing the Ryzen 5 8400F.

The Verdict

The benchmark data points to the Intel Core 5 221E as the superior processor for the vast majority of workloads. It wins 16 of 17 head-to-head tests, including all Cinebench multi-core and single-core tests, all PassMark math and processing tests, and all memory-intensive tests. The Intel part delivers a 19.6% lead across the entire Cinebench suite, a 20.1% lead in PassMark multithread, and an 11.1% lead in PassMark single-thread. Its 14 cores, 20 threads, 5.20 GHz boost clock, and 24 MB of shared L3 cache support these results.

The AMD Ryzen 5 8400F has one clear strength: extended instructions. Its 21.7% win in that specific test shows that the Zen 4 architecture with its 4 nm process and advanced instruction set can outperform Intel in narrowly defined computational tasks. Users running software that explicitly uses extended instruction sets should consider the AMD part. Additionally, the AMD processor uses the AM5 socket with 20 PCIe Gen 4 lanes, which may suit certain platform preferences.

The Intel Core 5 221E also offers practical advantages beyond raw scores. It supports both DDR4 and DDR5 memory, includes integrated graphics as a fallback, supports ECC memory, and provides PCIe Gen 5 connectivity. Its 65 W TDP matches the AMD part, so power consumption is not a differentiating factor. The Intel processor sits at the 87th percentile of all CPUs in the database, while the AMD part sits at the 77th percentile.

For rendering, compilation, data processing, general productivity, and single-threaded responsiveness, the Intel Core 5 221E is the data-backed choice. For workloads that depend heavily on extended instruction set throughput, the AMD Ryzen 5 8400F holds a measurable edge. The database records no other scenario where AMD wins.
