AMD Ryzen AI 7 345 vs Intel Core 7 253PTE Comparison

Where Each One Wins

The benchmark split is lopsided but not one-sided. The Intel Core 7 253PTE takes 13 of the 15 recorded head-to-head tests, while the AMD Ryzen AI 7 345 wins only 2. However, the AMD wins are not trivial: both are single-thread PassMark results, where the Ryzen posts 3875 against 3794, a 2.1% margin. That makes the Ryzen the better choice for lightly threaded workloads that rely on PassMark's single-thread measurement, such as certain legacy applications or responsiveness-oriented tasks.

Every other category belongs to Intel. The largest gaps appear in compute-heavy and multithreaded workloads. Cinebench R23 multicore shows Intel at 21276 versus 11461, a 46.1% deficit for AMD. passmark integer math shows a nearly identical gap: Intel scores 119552 against 63475, a 46.9% difference. These are not marginal wins; they indicate a decisive performance class separation in sustained parallel work.

The Intel part also wins in floating-point math (67209 versus 42621, 36.6% ahead), data encryption (15500 versus 11814, 23.8% ahead), and prime number finding (82 versus 62, 24.4% ahead). Even in the closest non-single-thread test, extended instructions, Intel wins by only 0.6% (17099 versus 17003), showing that the two parts are nearly identical in SIMD-heavy instruction throughput despite the broader gaps elsewhere.

The use-case split is therefore clear: Intel dominates rendering, encryption, compression, integer and floating-point math, physics simulation, and multithreaded PassMark workloads. AMD wins only the PassMark single-thread score, and by a slim margin. For users prioritizing parallel throughput, the Intel part is the clear leader. For users whose workload tracks PassMark's single-thread score, the AMD part holds a small but real edge.

Architecture Differences

The two processors come from opposite design philosophies. The AMD Ryzen AI 7 345 uses Krackan Point, built on the Ryzen AI 300 generation with Zen 5 / Zen 5c cores. It is manufactured on TSMC's 4 nm process. The Intel Core 7 253PTE uses Bartlett Lake, from the Core 7 generation, on Intel's 10 nm process. The process node difference is significant: 4 nm versus 10 nm gives AMD a density and efficiency advantage on paper, though the benchmark data shows Intel overcoming that with a larger core count and higher clocks.

Core configuration differs sharply. AMD fields 6 cores and 12 threads. Intel fields 10 cores and 20 threads. That 4-core, 8-thread advantage explains much of Intel's multicore lead. Cache hierarchies also differ in structure. Both use 80 KB of L1 per core, but AMD uses 1 MB of L2 per core while Intel uses 2 MB per core. The L3 cache is the biggest structural difference: AMD has 4 MB of L3, while Intel has 33 MB of shared L3. Intel's L3 is more than 8 times larger, which benefits workloads with large working sets.

Memory support diverges as well. AMD supports DDR5 and LPDDR5X; Intel supports DDR4 and DDR5. Intel adds ECC memory support, which AMD lacks. Both run dual-channel memory with identical 89.6 GB/s bandwidth. PCIe generation differs: AMD uses Gen 4 with 14 CPU lanes, Intel uses Gen 5 with 16 CPU lanes. That gives Intel both a newer PCIe standard and more lanes.

Integrated graphics also differ. AMD uses the Radeon 840M, while Intel uses UHD Graphics 730. The database does not include iGPU benchmark scores, so the comparison rests on specification only. Socket and market segment separate the two further: AMD uses Socket FP8 and targets mobile, while Intel uses Socket 1700 and targets desktop. The Intel part's launch date is listed as 2026-03-08, while AMD's is 2025-01-14. Both are marked Active in production status.

Head-to-Head Benchmarks

The largest Intel win is in passmark integer math, where it scores 119552 versus 63475, a 46.9% advantage. That is the widest margin in the entire comparison. Cinebench R23 multicore is close behind: Intel scores 21276 versus 11461, a 46.1% gap. These two tests establish the pattern: heavy parallel compute strongly favors Intel.

Cinebench R23 singlecore shows Intel at 3003 versus 1818, a 39.5% lead. This is notable because it contradicts the PassMark single-thread result. In Cinebench R15 singlecore, Intel also leads, 302 versus 271, a 10.3% margin. The PassMark single-thread test is the only single-core measurement where AMD wins, and it does so by just 2.1%. The database records both passmark_single_thread and passmark_singlethread with identical scores (3875 for AMD, 3794 for Intel), confirming the result is not an outlier.

Floating-point math shows Intel ahead by 36.6% (67209 versus 42621). Prime number finding shows Intel ahead by 24.4% (82 versus 62). Data encryption shows Intel ahead by 23.8% (15500 versus 11814). Multithread PassMark shows Intel ahead by 20.4% (25031 versus 19927). Cinebench R15 multicore shows Intel ahead by 20.1% (2144 versus 1712). Physics shows Intel ahead by 17.4% (1318 versus 1089). Data compression shows Intel ahead by 13.9% (275828 versus 237484). Random string sorting shows Intel ahead by 9.9% (28227 versus 25435). Extended instructions shows Intel ahead by just 0.6% (17099 versus 17003).

The pattern is consistent: Intel wins every Cinebench test, every PassMark compute test, and every PassMark memory-adjacent test. AMD wins only the PassMark single-thread score. The average benchmark scores reflect this: Intel averages 34962, AMD averages 29461. Intel's percentile ranking is 84 versus AMD's 81. Intel's nearest rivals include the Core i7-13800H and Core i9-12900HX, both within 0.1% of its average score. AMD's nearest rivals include the Ryzen 7 3800X and EPYC 9654, with the EPYC within 0.2%.

The Verdict

The data points to a clear performance hierarchy. The Intel Core 7 253PTE wins 13 of 15 head-to-head tests, including every Cinebench test and every PassMark compute test except single-thread. Its average benchmark score of 34962 is 18.7% higher than AMD's 29461. Its percentile rank of 84 versus 81 places it higher in the global CPU distribution. The multicore wins are especially decisive: 46.1% in Cinebench R23 multicore and 46.9% in integer math.

The AMD Ryzen AI 7 345 is the better choice only for workloads that match PassMark's single-thread score, where it leads by 2.1%. It also draws less power at 28 W versus 45 W, uses a smaller 4 nm process, and targets mobile platforms with Socket FP8. Those are meaningful for battery and thermal envelopes, but the benchmark data does not record any performance test where that efficiency advantage translates into a win beyond the single PassMark single-thread result.

The Intel part is a desktop processor with a higher boost clock (5.40 GHz versus 4.60 GHz), more cores, more threads, a much larger L3 cache, ECC support, and PCIe Gen 5. It is also the only one of the two with a recorded launch MSRP at $384. The AMD part is a mobile processor with a higher base clock (2.00 GHz versus 1.80 GHz), a smaller process node, and a lower TDP.

For rendering, encryption, compression, math workloads, physics simulation, and general multithreaded throughput, the Intel Core 7 253PTE is the faster processor by a wide margin. For single-thread PassMark performance specifically, the AMD Ryzen AI 7 345 holds a narrow edge. The overall average benchmark score and the near-total sweep of head-to-head tests make the Intel part the stronger option in the recorded data.
