AMD Ryzen 5 40 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep in favor of the Intel Core 9 273PE across all 15 head-to-head benchmark comparisons. The AMD Ryzen 5 40 does not win a single test. The largest margin appears in the prime number search workload, where the Intel part scores 203 against 20 for the AMD, a delta of -90.1%. This is the most lopsided result in the dataset.

Multi-threaded performance reveals the scale of the gap. In Cinebench R23 multi-core, the Intel Core 9 273PE posts 31288 points versus 4841 for the AMD Ryzen 5 40, a delta of -84.5%. The older Cinebench R15 multi-core test shows the same pattern: 3153 against 790, a -74.9% difference. PassMark multi-thread follows with 36810 versus 9341, a -74.6% delta.

Single-thread performance is closer, though still decisively in Intel's favor. Cinebench R23 single-core gives the Intel part 4417 points against 1150, a -74% delta. Cinebench R15 single-core shows 445 versus 165.5, a -62.8% difference. The PassMark single-thread test narrows the margin to -32.1%, with scores of 3650 and 2477. This remains the smallest relative gap in the entire benchmark set, indicating that the AMD part's per-core efficiency is its strongest attribute, but it does not translate into a win anywhere.

The productivity and encryption workloads confirm the trend. PassMark data compression scores 405885 for the Intel part versus 141533, a -65.1% delta. Data encryption shows 22719 against 6646, a -70.7% difference. Extended instruction throughput gives 24630 versus 6437, a -73.9% delta. Floating point math delivers 107884 against 15194, a -85.9% gap, while integer math sits at 139410 versus 31598, a -77.3% delta. Physics simulation shows 3120 versus 432, a -86.2% difference. Random string sorting completes the set at 45098 versus 15124, a -66.5% delta.

The average benchmark score reflects the overall positioning. The Intel Core 9 273PE records an average of 49845, placing it in the 90th percentile of all CPUs in the database. The AMD Ryzen 5 40 averages 15882, sitting in the 70th percentile. The delta between the two average scores is approximately 68%, based on the raw values.

Nearest rival data confirms the Intel part is competitive with substantially larger desktop processors. Its average score of 49845 sits within 0.1% of the AMD Ryzen AI Max+ 388 (49796), 0.9% above the Intel Core i5-14600KF (49394), and within 1.2% of the AMD Ryzen AI 9 HX PRO 370 (50448). The AMD Ryzen 5 40, by contrast, holds its 70th percentile position with an average score within 0.4% of the AMD EPYC 9354P (15826) and within 0.4% of the AMD EPYC 9334 (15940). The nearest rival sets indicate that both processors perform at a level consistent with their respective market segments, but those segments are far apart in absolute throughput.

Architecture Differences

The two processors come from different design philosophies and target different physical envelopes. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, built on a 6 nm process at TSMC. The Intel Core 9 273PE uses the Bartlett Lake codename, built on a 10 nm process at Intel. The smaller process node for the AMD part does not compensate for the core count difference in the benchmark results.

Core and thread counts diverge sharply. The AMD Ryzen 5 40 has 4 cores and 8 threads. The Intel Core 9 273PE has 12 cores and 24 threads. This 3x core advantage and 3x thread advantage aligns with the multi-threaded benchmark margins, which cluster mostly between -65% and -90%. The single-thread margin is smaller, which is consistent with the higher boost clock on the Intel part.

Clock speeds differ in both base and boost operation. The AMD Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The Intel Core 9 273PE has a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The base clock is higher on the AMD chip, but the boost clock is 1.40 GHz higher on the Intel chip. The single-thread benchmark results suggest that the sustained boost behavior favors the Intel part.

Cache hierarchies are structurally different. The AMD Ryzen 5 40 has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel Core 9 273PE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The L3 cache difference is substantial: 36 MB versus 4 MB. The larger shared cache likely contributes to the Intel part's advantage in data compression and random string sorting workloads.

Memory support also differs. The AMD Ryzen 5 40 supports LPDDR5 memory over a dual-channel bus with 88.0 GB/s of bandwidth. The Intel Core 9 273PE supports both DDR4 and DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth. The bandwidth figures are close, but the Intel part adds ECC memory support, which the AMD part lacks. The Intel part also has a different PCIe configuration: Gen 5 with 16 lanes from the CPU, versus Gen 3 with 4 lanes from the AMD CPU.

Integrated graphics differ as well. The AMD Ryzen 5 40 includes a Radeon 610M. The Intel Core 9 273PE includes UHD Graphics 730. The database does not include graphics benchmarks, so no performance comparison is possible from the recorded data.

The AMD part is a mobile segment processor on AMD Socket FT6. The Intel part is a desktop segment processor on Intel Socket 1700. The thermal design power values reflect this: the AMD part is rated at 15 W, while the Intel part is rated at 65 W. The release dates show the AMD part entering the database on 2025-09-30 and the Intel part on 2026-03-08. The Intel part also carries a launch MSRP of $549.

The Verdict

The benchmark data presents a one-sided comparison. The Intel Core 9 273PE outperforms the AMD Ryzen 5 40 in every recorded test, with margins ranging from -32.1% in PassMark single-thread to -90.1% in prime number search. The average benchmark score difference is substantial: 49845 versus 15882.

The AMD Ryzen 5 40 is a 4-core, 8-thread mobile processor with a 15 W TDP, a 2.80 GHz base clock, and a 4.30 GHz boost clock. Its performance profile places it in the 70th percentile of all CPUs, near the AMD EPYC 75F3 (0.1% delta) and the Intel Core Ultra 5 134U (-0.2% delta). For workloads that fit within its 4 MB of L3 cache and 4 PCIe Gen 3 lanes, it delivers results consistent with that class of hardware.

The Intel Core 9 273PE is a 12-core, 24-thread desktop processor with a 65 W TDP, a 2.30 GHz base clock, and a 5.70 GHz boost clock. It ranks in the 90th percentile, within 0.1% of the AMD Ryzen AI Max+ 388 and 0.9% above the Intel Core i5-14600KF. The larger cache (36 MB L3), PCIe Gen 5 support, and ECC memory capability give it a broader feature set beyond raw throughput.

The choice between these two processors depends on the application segment. The AMD part targets mobile systems where the 15 W TDP and LPDDR5 support are relevant. The Intel part targets desktop systems where the 65 W TDP, DDR4/DDR5 compatibility, and ECC memory support matter. The benchmark data does not show any workload where the AMD part is competitive with the Intel part on raw performance.
