AMD Ryzen AI 7 345 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded data for these two processors could hardly be more one-sided. Across the 15 head-to-head benchmark comparisons in the database, the Intel Core 9 273PE claims 13 victories, while the AMD Ryzen AI 7 345 manages only two wins. The margin of Intel's dominance varies by workload, but the pattern is consistent: in almost every measurable category, the Intel part delivers substantially higher scores.

The largest gap appears in Cinebench R23 multi-core, where the Intel Core 9 273PE scores 31,288 against the AMD Ryzen AI 7 345's 11,461. That is a 63.4% deficit for the AMD processor, meaning the Intel chip completes the multi-threaded render workload in roughly a third of the time. Similarly, in Cinebench R15 multi-core, Intel scores 3,153 versus AMD's 1,712, a 45.7% margin. The single-core Cinebench results tell the same story: Intel leads by 39.1% in R15 (445 versus 271) and by 58.8% in R23 (4,417 versus 1,818). These are not narrow wins; they are decisive gaps across both legacy and current render benchmarks.

The PassMark suite reinforces the Intel advantage with equally large margins. In floating point math, Intel scores 107,884 against AMD's 42,621, a 60.5% difference. Integer math shows Intel at 139,410 versus 63,475, a 54.5% lead. Physics simulation tests put Intel at 3,120 versus AMD's 1,089, a 65.1% margin, which is the second-largest percentage gap in the entire comparison. Prime number finding favors Intel even more heavily: 203 versus 62, a 69.5% deficit for AMD, the largest single percentage gap recorded.

Data-focused workloads also favor Intel. Data compression scores 405,885 for Intel versus 237,484 for AMD, a 41.5% difference. Data encryption shows Intel at 22,719 versus 11,814, a 48% margin. Extended instruction tests put Intel at 24,630 versus 17,003, a 31% lead, which is the smallest Intel advantage in the entire dataset. Random string sorting follows the trend: Intel scores 45,098, AMD scores 25,435, a 43.6% gap. The multi-threaded PassMark score is 36,810 for Intel versus 19,927 for AMD, a 45.9% difference.

The only two benchmarks where the AMD Ryzen AI 7 345 comes out ahead are the PassMark single-thread tests. Both the "single_thread" and "singlethread" entries record the same scores: AMD at 3,875 and Intel at 3,650. That gives AMD a 6.2% advantage in each. It is a narrow but consistent win, suggesting that the AMD processor's per-core efficiency in certain lightweight workloads exceeds what the Intel chip can manage, even though Intel dominates almost everything else.

Looking at the broader database context, the Intel Core 9 273PE sits at the 90th percentile among all CPUs, with an average benchmark score of 49,845. Its nearest rivals include the AMD Ryzen AI Max+ 388 (average score 49,796, delta 0.1%), the Intel Core i5-14600KF (49,394, delta 0.9%), the Intel Core i9-13980HX (50,398, delta -1.1%), and the AMD Ryzen AI 9 HX PRO 370 (50,448, delta -1.2%). The AMD Ryzen AI 7 345, by contrast, ranks at the 81st percentile with an average score of 29,461, placing it near the AMD Ryzen 7 3800X (29,447, delta 0%), the AMD EPYC 9654 (29,409, delta 0.2%), the Intel Core i5-13500HX (29,270, delta 0.7%), and the AMD Ryzen 7 PRO 5755GE (29,656, delta -0.7%). The gap between the two processors in average score is roughly 20,000 points, which is substantial.

The Verdict

The benchmark data indicates that the Intel Core 9 273PE is the far stronger performer in nearly every workload category measured. Its 13 wins versus 2 wins for the AMD Ryzen AI 7 345 is not a close contest. For users prioritizing multi-threaded rendering, physics simulation, data compression, encryption, or any of the PassMark math workloads, the Intel part delivers anywhere from 31% to 69.5% higher scores. The Intel processor also leads in both Cinebench R15 and R23 single-core tests, with margins of 39.1% and 58.8% respectively.

The AMD Ryzen AI 7 345 does hold a genuine advantage in PassMark single-thread performance, where it beats Intel by 6.2%. That suggests that in workloads that are strictly single-threaded and not heavily reliant on raw clock speed, the AMD chip can keep pace or edge ahead. However, that single win is dwarfed by the scale of Intel's victories elsewhere. The Intel Core 9 273PE also carries a higher percentile ranking, 90th versus 81st, and a substantially higher average benchmark score.

From the data alone, the Intel Core 9 273PE is the appropriate choice for users who need maximum throughput across a broad range of compute-intensive tasks. The AMD Ryzen AI 7 345 may appeal to those whose primary workloads are single-threaded and light, where its PassMark single-thread score of 3,875 outpaces Intel's 3,650. But for multi-core, mixed-workload scenarios, the Intel part is consistently and significantly ahead.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen AI 7 345 has 6 cores and 12 threads, while the Intel Core 9 273PE has 12 cores and 24 threads. Base clock speeds are 2.00 GHz for AMD and 2.30 GHz for Intel. Boost clocks differ more significantly: AMD reaches 4.60 GHz, Intel reaches 5.70 GHz. Thermal design power is also distinct, with AMD rated at 28 watts and Intel at 65 watts.

The cache hierarchies differ notably. Both have 80 KB of L1 cache per core. L2 cache is 1 MB per core for AMD and 2 MB per core for Intel. L3 cache is much larger on the Intel side: 4 MB for AMD versus 36 MB shared for Intel.

Memory support differs as well. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use a dual-channel memory bus, and both have a memory bandwidth of 89.6 GB/s. ECC memory support is present on the Intel part but not on the AMD part.

PCIe capabilities differ: AMD offers Gen 4 with 14 lanes (CPU only), while Intel offers Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: AMD uses Radeon 840M, Intel uses UHD Graphics 730. The market segment is mobile for AMD and desktop for Intel. Sockets differ accordingly: AMD Socket FP8 for AMD, Intel Socket 1700 for Intel. The Intel processor has a launch MSRP of $549.

Architecture Differences

The AMD Ryzen AI 7 345 is built on the Krackan Point codename, using the Ryzen AI 300 generation with Zen 5 / Zen 5c cores. It is manufactured on a 4 nm process at TSMC. The Intel Core 9 273PE uses the Bartlett Lake codename, from the Core 9 generation, and is manufactured on a 10 nm process at Intel. The process node difference is substantial, with AMD using a more advanced node.

The core count difference, 6 versus 12, reflects a fundamentally different design approach. AMD uses a hybrid arrangement of Zen 5 and Zen 5c cores within its 6-core configuration, while Intel uses its Bartlett Lake architecture across 12 cores. The thread counts, 12 versus 24, scale directly with core counts.

Cache architecture differs beyond capacity. AMD allocates L2 cache per core at 1 MB, while Intel allocates 2 MB per core. The L3 cache is 4 MB total for AMD, while Intel provides 36 MB shared. This difference in shared cache size, 36 MB versus 4 MB, is one of the largest architectural gaps between the two parts.

The Intel processor includes ECC memory support and PCIe Gen 5 connectivity, while the AMD part supports PCIe Gen 4 and does not include ECC. The Intel part also includes DDR4 memory support in addition to DDR5, while AMD supports DDR5 and LPDDR5X. These architectural choices position the Intel part for desktop workloads with higher memory capacity and error correction, while the AMD part targets mobile platforms with lower power consumption and a more advanced manufacturing process.
