AMD Ryzen AI 5 340 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen AI 5 340 and the Intel Core 9 273PE is remarkably one-sided, but the two tests where AMD takes the lead are revealing. The Intel part wins 13 of the 15 recorded head-to-head comparisons, while the AMD chip claims only 2. Those two wins come in the PassMark single-thread test, where the Ryzen AI 5 340 scores 3683 against 3650 for the Intel Core 9 273PE, a margin of 0.9 percent. Both the passmark_single_thread and passmark_singlethread entries show the same result, which confirms the AMD processor holds a narrow but consistent advantage in that specific workload.

Every other benchmark in the head-to-head set goes to Intel, and many by substantial margins. The largest gap appears in PassMark physics, where Intel scores 3120 versus AMD's 1095, a deficit of 64.9 percent for the AMD chip. PassMark find prime numbers shows a similar pattern, with Intel at 203 and AMD at 72, a 64.5 percent difference. Floating point math also heavily favors Intel, 107884 against 39967, a 63 percent gap. These three tests point to raw computational throughput as the Intel processor's strongest domain.

The Cinebench results tell the same story. In Cinebench R23 multi-core, Intel scores 31288 while AMD manages 12532, a 59.9 percent deficit. Single-core in the same test shows Intel at 4417 versus 1915.5 for AMD, a 56.6 percent gap. Cinebench R15 multi-core has Intel at 3153 against AMD's 1915, a 39.3 percent difference, and single-core shows Intel at 445 versus 242.6, a 45.5 percent gap. These results indicate the Intel Core 9 273PE delivers more than double the multi-threaded rendering performance of the AMD Ryzen AI 5 340 in the R23 test.

PassMark integer math shows Intel at 139410 against AMD's 63078, a 54.8 percent deficit. Data encryption also goes to Intel, 22719 versus 11470, a 49.5 percent gap. Data compression shows Intel at 405885 and AMD at 229796, a 43.4 percent difference. Random string sorting, extended instructions, and multithread tests all follow the same direction, with Intel leading by margins between 33.3 and 47 percent. The multithread score of 36810 for Intel versus 19506 for AMD represents a 47 percent gap, confirming that heavily threaded workloads favor the Intel processor by a wide margin.

The average benchmark scores in the database reinforce this trend. The AMD Ryzen AI 5 340 sits at an average benchmark score of 25981, while the Intel Core 9 273PE reaches 49845. The Intel chip also ranks at the 90th percentile among all CPUs in the database, while the AMD chip ranks at the 78th percentile. Even the nearest rivals for each processor highlight the performance tier difference. The AMD chip's closest competitors include the Intel Core i7-14701TE at a 0.1 percent difference in average score, the AMD Ryzen 5 8640HS at 0.5 percent, and the Intel Core i7-11700K at 0.7 percent. The Intel Core 9 273PE, by contrast, sits alongside the AMD Ryzen AI Max+ 388 at 0.1 percent, the Intel Core i5-14600KF at 0.9 percent, and the Intel Core i9-13980HX at 1.1 percent. These neighboring parts occupy a much higher performance stratum.

Architecture Differences

The two processors come from fundamentally different design lineages. The AMD Ryzen AI 5 340 uses Zen 5 architecture under the Krackan Point codename, part of the Ryzen AI 300 generation that mixes Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. The Intel Core 9 273PE uses the Bartlett Lake codename and is fabricated on a 10 nm process at Intel's own foundries. The process node difference alone suggests the AMD chip benefits from a more advanced manufacturing technology, yet the benchmark results show the Intel part overcoming that disadvantage through sheer core count and clock speed.

Core counts differ sharply. The AMD Ryzen AI 5 340 has 6 cores and 12 threads, while the Intel Core 9 273PE has 12 cores and 24 threads. That is exactly double the core and thread count. Cache configuration also diverges. Both processors use 80 KB of L1 cache per core, but the L2 cache differs: AMD provides 1 MB per core, while Intel provides 2 MB per core. The L3 cache shows an even larger gap, with AMD offering 8 MB total and Intel offering 36 MB shared. This larger cache pool on the Intel side likely contributes to its strong showing in compression and encryption workloads, where data reuse patterns benefit from larger on-chip storage.

Clock speeds favor Intel as well. The AMD chip has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The Intel chip has a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The higher boost clock gives Intel a 0.90 GHz advantage at peak frequency, which helps explain its dominant single-core Cinebench results. Thermal design power also differs substantially: the AMD part is rated at 28 watts, while the Intel part is rated at 65 watts. The higher power envelope allows Intel to sustain higher clocks under load, but it also positions the two chips in very different usage contexts.

Platform support separates them further. The AMD Ryzen AI 5 340 uses the AMD Socket FP8 and targets the mobile market segment. The Intel Core 9 273PE uses Intel Socket 1700 and targets desktop systems. Memory support also differs. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both run dual-channel memory buses with identical 89.6 GB/s memory bandwidth. ECC memory support is present on the Intel chip but absent on the AMD chip. PCIe connectivity differs as well, with AMD offering Gen 4 with 16 CPU lanes and Intel offering Gen 5 with 16 CPU lanes. Integrated graphics differ too: the AMD chip includes a Radeon 840M, while the Intel chip includes UHD Graphics 730.

The production status for both is listed as Active. Release dates differ, with the AMD chip releasing on January 5, 2025, and the Intel chip releasing on March 8, 2026. Neither processor has an unlocked multiplier. The die size for the AMD chip is listed as 195 mm², while no die size is recorded for the Intel chip.

The Verdict

The data points to two chips built for different purposes. The Intel Core 9 273PE is the clear performance leader in nearly every measured workload. Its 12 cores and 24 threads, combined with a 5.70 GHz boost clock and 36 MB of shared L3 cache, deliver results that dwarf the AMD Ryzen AI 5 340 in multi-threaded rendering, physics simulation, encryption, compression, and floating point math. The Cinebench R23 multi-core score of 31288 versus 12532 represents a 59.9 percent advantage. The PassMark multithread score of 36810 versus 19506 shows a 47 percent advantage. For anyone relying on heavily parallel workloads, the Intel part is the obvious choice based strictly on these measurements.

The AMD Ryzen AI 5 340 does hold one meaningful edge: single-thread PassMark performance. Its score of 3683 edges out Intel's 3650 by 0.9 percent. That is a slim margin, and it does not translate into Cinebench single-core superiority, where Intel leads by 56.6 percent in R23 and 45.5 percent in R15. The AMD chip also operates at a much lower 28 watt TDP compared to Intel's 65 watts, which positions it for battery-conscious mobile designs. The AMD part uses a smaller 4 nm process from TSMC, supports LPDDR5X memory, and targets the mobile segment with the AMD Socket FP8.

The average benchmark score gap is stark: 25981 for AMD versus 49845 for Intel. The percentile ranking also separates them, 78th for AMD and 90th for Intel. The Intel Core 9 273PE launch MSRP is $549. The database records no launch MSRP for the AMD chip. For desktop users who need maximum throughput, the Intel Core 9 273PE delivers across the board. For mobile systems where power efficiency and a compact socket matter, the AMD Ryzen AI 5 340 offers a competitive single-thread PassMark result at a fraction of the power envelope.
