AMD Ryzen 7 5700X3D vs Intel Core 5 221E Comparison

The Verdict

The recorded data presents a clear performance hierarchy between these two desktop processors. The Intel Core 5 221E wins 14 of the 17 head-to-head benchmark comparisons, while the AMD Ryzen 7 5700X3D claims only 3 wins. The Intel part also holds a higher overall percentile ranking at 87 versus 77 for the AMD chip, and its average benchmark score of 40144 substantially exceeds the AMD's 24709. The Intel Core 5 221E is the stronger choice for users who prioritize broad multi-threaded and single-threaded performance, as it leads in every Cinebench test and in most PassMark workloads. The AMD Ryzen 7 5700X3D, however, demonstrates specific strengths in extended instruction handling, prime number calculation, and physics simulation, which makes it relevant for those specialized workloads. The data indicates that the Intel processor delivers higher raw throughput across most general computing tasks, while the AMD chip offers targeted advantages in particular computational patterns.

Architecture Differences

The two processors come from different manufacturing and design philosophies. The AMD Ryzen 7 5700X3D uses the Zen 3 architecture under the Vermeer codename, built on a 7 nm process at TSMC. It contains 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. The chip integrates 8,850 million transistors on a 74 mm² die. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a large 96 MB shared L3 cache. This substantial L3 allocation is the defining feature of the X3D lineup and explains its performance characteristics in cache-sensitive workloads.

The Intel Core 5 221E uses the Bartlett Lake codename, built on a 10 nm process at Intel. It provides 14 cores and 20 threads, with a base clock of 2.70 GHz and a boost clock of 5.20 GHz. The die size is considerably larger at 257 mm². Its cache layout differs sharply: 80 KB of L1 per core, 2 MB of L2 per core, and only 24 MB of shared L3. The higher core count and thread count give the Intel part a structural advantage in parallel workloads, while the higher boost clock supports its single-thread dominance. The Intel processor also supports both DDR4 and DDR5 memory, whereas the AMD chip is limited to DDR4. Memory bandwidth figures reflect this: the Intel part reaches 89.6 GB/s against the AMD's 51.2 GB/s. The Intel chip includes integrated graphics (UHD Graphics 730), while the AMD processor has no integrated graphics. PCIe support also differs, with Intel offering Gen 5 with 16 CPU lanes and AMD offering Gen 4 with 20 CPU lanes. Both support ECC memory, and both have locked multipliers.

Where Each One Wins

The Intel Core 5 221E dominates in almost every measured category. All Cinebench R15, R20, and R23 tests, both single-core and multi-core, go to the Intel part. PassMark integer math, floating point math, data compression, data encryption, random string sorting, multithread, and single-thread tests all favor Intel. The single-thread gap is especially pronounced, with Intel leading by 28.4 percent. This pattern suggests the Intel processor is better suited for general productivity, content creation, and any workload that scales with core count or benefits from high clock speeds.

The AMD Ryzen 7 5700X3D wins in three specific tests: PassMark extended instructions (by 16.4 percent), PassMark find prime numbers (by 29.5 percent), and PassMark physics (by 20.4 percent). The prime number result aligns with the large 96 MB L3 cache, which reduces memory latency for repetitive data access patterns. The physics win may also reflect cache behavior in simulation-style workloads. The extended instructions result indicates that the AMD architecture handles certain instruction set extensions more efficiently. These wins, while few, are meaningful for users running scientific computing, encryption-related instruction workloads, or physics simulations that match these patterns.

Head-to-Head Benchmarks

The largest single margin in the entire comparison belongs to the Intel Core 5 221E in PassMark floating point math, where it scores 79028 against the AMD's 46492, a difference of 41.2 percent. This is a decisive result and indicates that the Intel architecture handles floating point operations at a much higher throughput. The integer math test also goes decisively to Intel, with a score of 117813 versus 81257, a 31 percent gap. These two results alone establish the Intel part as the superior choice for mathematically intensive workloads.

The single-thread tests reinforce the Intel advantage. PassMark single-thread shows 4147 for Intel versus 2970 for AMD, a 28.4 percent lead. Cinebench R23 single-core shows 3661 versus 3157, a 13.8 percent gap. The same 13.8 percent margin appears in Cinebench R20 single-core (1537 versus 1325) and Cinebench R15 single-core (368 versus 318, a 13.6 percent gap). The consistency of this margin across different Cinebench versions suggests a stable architectural difference in single-thread capability.

Multi-threaded performance also favors Intel across the board. Cinebench R23 multi-core scores 25933 for Intel versus 22366 for AMD, again a 13.8 percent gap. Cinebench R20 multi-core shows 10891 versus 9393, and Cinebench R15 multi-core shows 2613 versus 2254. PassMark multithread shows 30510 versus 26318, a 13.7 percent gap. The multi-thread margins are nearly identical to the single-thread margins, indicating that the Intel advantage scales evenly across thread counts rather than coming solely from its additional cores.

Memory-oriented and data-processing tasks also favor Intel. PassMark random string sorting shows 37686 versus 31492, a 16.4 percent lead. Data compression shows 324285 versus 307237, a 5.3 percent lead. Data encryption shows 19205 versus 18788, a smaller 2.2 percent gap. These results suggest that even though the AMD processor has a much larger L3 cache, the Intel processor still manages to win in most data manipulation tasks.

The AMD Ryzen 7 5700X3D wins its three tests by notable margins. The largest AMD win is in PassMark find prime numbers, with a score of 224 versus 173, a 29.5 percent advantage. PassMark physics shows 2686 versus 2230, a 20.4 percent lead. PassMark extended instructions shows 21202 versus 18216, a 16.4 percent lead. These wins demonstrate that the AMD processor retains competitive strength in specific algorithmic patterns, even though it trails in the majority of tests.

The overall win count stands at 14 for Intel and 3 for AMD. The Intel processor also holds a higher percentile ranking among all CPUs (87 versus 77) and a higher average benchmark score (40144 versus 24709). The nearest rival data for the Intel part shows it trading closely with the AMD Ryzen 7 7700 (0.2 percent delta) and the AMD Ryzen AI 9 365 (0.2 percent delta), while the AMD Ryzen 7 5700X3D sits near the AMD Ryzen 5 7600X3D (minus 0.1 percent) and the Intel Core i5-12450HX (0.5 percent). This places the two processors in different competitive tiers according to the database measurements.
