AMD Ryzen 3 3100U vs Intel Core 5 223PE Comparison

Where Each One Wins

The recorded benchmark data presents an unusually one-sided comparison. Across the eleven shared PassMark tests, the Intel Core 5 223PE wins every single contest. The AMD Ryzen 3 3100U does not secure a single victory in any measured workload. This is not a narrow margin situation; the Intel part leads by substantial double-digit percentages in all but one category.

The Intel Core 5 223PE dominates in multi-threaded throughput. In PassMark multithread, it scores 31,124 against the AMD's 3,348, a delta of 89.2 percent. The integer math test shows a similar pattern: 99,819 versus 8,873, an 91.1 percent advantage. Floating point math follows with 76,468 against 5,854, a 92.3 percent gap. These are not incremental gains; they represent a completely different performance tier.

The single-thread results are closer but still firmly in Intel's favor. The Intel Core 5 223PE records 4,219 in PassMark single-thread, while the AMD Ryzen 3 3100U manages 1,592. That is a 62.3 percent deficit for the AMD part, the smallest relative gap in the entire comparison. Even so, the Intel processor delivers roughly 2.65 times the single-thread score.

The AMD Ryzen 3 3100U does have a defining characteristic: its power envelope. The database records a 15-watt TDP for the AMD mobile processor, versus 65 watts for the Intel desktop chip. The AMD part targets the mobile segment with an FP5 socket, while the Intel chip is a desktop processor on Socket 1700. The AMD's efficiency-focused design explains its lower scores, but the data does not show any workload where that efficiency translates into a benchmark win.

In data compression, the Intel part scores 346,623 against 38,455. Data encryption shows 18,448 versus 1,972. Extended instructions record 24,672 against 2,116. Prime number finding, a test sensitive to integer throughput, shows 159 versus 18. Random string sorting records 35,798 versus 4,666. Physics simulation, which often scales with core count, shows 2,493 versus 232. Every category lands in the same direction.

The Verdict

The benchmark data indicates that the Intel Core 5 223PE is the decisive performer in every measured category. The Intel chip's 87th percentile ranking among all CPUs in the database contrasts sharply with the AMD Ryzen 3 3100U's 62nd percentile. The average benchmark score of 40,585 for the Intel part versus 6,247 for the AMD part reinforces this gap. The Intel Core 5 223PE sits among rivals like the Intel Core 7 253PE, which scores 40,557 with a 0.1 percent delta, and the AMD Ryzen AI 5 PRO 435G at 40,718 with a 0.3 percent delta. The AMD Ryzen 3 3100U, by contrast, sits near the AMD EPYC 7272 at 6,186 and the Intel Core i9-7940X at 6,147, a 1.6 percent delta in both cases.

For workloads that demand multi-threaded performance, the Intel Core 5 223PE delivers between 87 and 92.3 percent more throughput depending on the specific test. The smallest advantage is 62.3 percent in single-thread. There is no scenario in the recorded data where the AMD Ryzen 3 3100U offers a performance benefit.

The AMD part does carry the distinction of a 15-watt TDP, which positions it for power-constrained mobile systems. The Intel chip's 65-watt TDP and desktop socket indicate a different design target. Users constrained by thermal or power limits may find the AMD part appropriate for basic mobile tasks. Users seeking performance in any benchmark category should select the Intel Core 5 223PE.

The Intel Core 5 223PE also supports ECC memory, a feature absent from the AMD Ryzen 3 3100U. Its memory bandwidth of 89.6 GB/s exceeds the AMD's 38.4 GB/s. The Intel part supports both DDR4 and DDR5, while the AMD part supports only DDR4. The Intel chip's PCIe Gen 5 interface with 16 CPU lanes outpaces the AMD's PCIe Gen 3. These platform-level differences reinforce the performance separation.

Head-to-Head Benchmarks

The largest relative win for the Intel Core 5 223PE appears in floating point math. The Intel part scores 76,468 against the AMD's 5,854, a 92.3 percent delta. This test exercises heavy mathematical computation and benefits from the Intel chip's 8 cores and 16 threads. The AMD's 2 cores and 2 threads cannot match that parallel throughput.

Extended instructions show a 91.4 percent delta. The Intel part records 24,672, while the AMD part scores 2,116. This test measures SIMD-style instruction throughput, where the Intel chip's architecture and higher core count provide a substantial edge.

Integer math delivers a 91.1 percent delta. The Intel score of 99,819 dwarfs the AMD's 8,873. This workload scales well with both core count and clock speed. The Intel chip's 5.20 GHz boost clock, compared to the AMD's 3.20 GHz, contributes to this result.

Physics simulation shows a 90.7 percent delta. The Intel part scores 2,493 against 232. This test typically responds to multi-core scaling, and the Intel chip's 8 cores provide a clear advantage over the AMD's 2.

Data encryption records an 89.3 percent delta. The Intel part scores 18,448, while the AMD manages 1,972. Cryptographic workloads often benefit from modern instruction extensions and higher memory bandwidth. The Intel part's 89.6 GB/s memory bandwidth supports this result.

Multithread performance shows an 89.2 percent delta. The Intel score of 31,124 versus the AMD's 3,348 reflects the core and thread disparity. The Intel chip has 8 cores and 16 threads; the AMD has 2 cores and 2 threads.

Data compression shows an 88.9 percent delta. The Intel part scores 346,623 against 38,455. Compression algorithms rely on memory bandwidth and integer throughput, both of which favor the Intel chip.

Prime number finding records an 88.7 percent delta. The Intel part scores 159 versus 18. This test is highly sensitive to integer performance and cache behavior. The Intel chip's 24 MB shared L3 cache versus the AMD's 4 MB shared L3 provides a structural advantage.

Random string sorting shows an 87 percent delta. The Intel part scores 35,798 against 4,666. Sorting workloads depend on memory subsystem performance and per-core efficiency.

The smallest delta is single-thread performance at 62.3 percent. The Intel part scores 4,219 against 1,592. Even in a test that does not scale with core count, the Intel chip's higher boost clock and newer architecture produce a decisive win.
