AMD Ryzen 7 PRO 8845HS vs Intel Core i9-13905H Comparison

The Intel Core i9-13905H and AMD Ryzen 7 PRO 8845HS are both mobile processors designed for high-performance laptops, but they approach the task from opposite design philosophies. The Intel part, from the Raptor Lake-H generation, packs 14 cores and 20 threads with a boost clock of 5.40 GHz, while the AMD part, based on Zen 4 Hawk Point, offers 8 cores and 16 threads with a 5.10 GHz boost. In the database's head-to-head tests, Intel wins 9 of 17 comparisons and AMD wins 8, with average benchmark scores of 40313 and 39325 respectively. Both sit near the top of the overall CPU percentile rankings, at the 87th and 86th percentiles.

Head-to-Head Benchmarks

The most decisive Intel victories come in physics and prime number workloads. In Passmark physics, Intel scores 2054 against AMD's 1389, a 47.9% lead. In find prime numbers, Intel scores 122 versus 87, a 40.2% advantage. Floating point math also favors Intel heavily: 73434 vs 58965, a 24.5% gap. In Cinebench R15 multi-core, Intel leads 2857 to 2476, a 15.4% margin. Smaller but consistent wins appear in integer math (101716 vs 97625, 4.2%), multithread (29779 vs 28572, 4.2%), data compression (354330 vs 343952, 3%), and both Cinebench R20 tests (multi-core 10605 vs 10317, 2.8%; single-core 1497 vs 1456, 2.8%).

AMD's strongest result is in Cinebench R23 single-core, where it scores 3468 against Intel's 2020, a 41.8% lead. The R15 single-core test shows a 29.5% advantage (349 vs 246). In Cinebench R23 multi-core, AMD wins 24565 to 20034, an 18.4% margin. Extended instructions favor AMD by 16.3% (25434 vs 21297), and random string sorting by 10.5% (41867 vs 37460). The Passmark single-thread score is close, with AMD at 3762 vs 3703, a 1.6% edge, and data encryption is essentially tied at 20487 vs 20464, a 0.1% difference.

The pattern is clear: Intel dominates in physics, prime number generation, and floating-point math, while AMD takes the lead in single-threaded Cinebench tests and extended instruction workloads. The overall average benchmark score, however, is only a few hundred points apart, with Intel at 40313 and AMD at 39325.

Architecture Differences

The two processors are built on fundamentally different silicon. Intel uses Raptor Lake, a 10nm process from Intel's own foundry, while AMD uses Zen 4 on a 4nm process from TSMC. The transistor count is only listed for AMD, at 25,000 million, and the die size differs: Intel's is 257 mm², AMD's is 178 mm². Core configuration diverges sharply: Intel has 14 cores and 20 threads, AMD has 8 cores and 16 threads. Cache hierarchies also differ: Intel provides 80 KB L1 and 2 MB L2 per core, with 24 MB shared L3; AMD provides 64 KB L1 and 1 MB L2 per core, with 16 MB shared L3. Memory support: Intel accepts both DDR4 and DDR5, while AMD is DDR5-only. AMD lists a memory bandwidth of 89.6 GB/s; Intel does not specify one. ECC memory is supported on AMD but not on Intel. PCIe connectivity: Intel offers Gen5 with 8 lanes, AMD offers Gen4 with 20 lanes. Integrated graphics: Intel has Iris Xe Graphics 96EU, AMD has Radeon 780M. The sockets are different: Intel BGA 1744 vs AMD Socket FP7. Release dates: Intel January 2023, AMD April 2024.

Where Each One Wins

Based on the recorded benchmark results, Intel is the stronger choice for workloads that stress multi-threaded integer and floating-point performance. The physics test, which often correlates with simulation and gaming physics, shows a 47.9% Intel advantage. Prime number generation, a classic CPU-bound task, also favors Intel by 40.2%. Floating-point math, integer math, and multithread scores all lean Intel, with leads of 24.5%, 4.2%, and 4.2% respectively. Data compression also goes to Intel by 3%. For users running Cinebench R15 or R20 multi-threaded renders, Intel holds a lead, though the margin shrinks in R20 (2.8%) and reverses in R23, where AMD wins by 18.4%.

AMD, on the other hand, excels in single-threaded performance. The Cinebench R23 single-core score is 41.8% higher, and R15 single-core is 29.5% higher. The Passmark single-thread score is also slightly higher, by 1.6%. Extended instruction workloads, which may include AVX-512 or similar, show a 16.3% AMD advantage. Random string sorting, a memory-latency-sensitive test, goes to AMD by 10.5%. Data encryption is essentially a tie, with AMD ahead by 0.1%. For users who prioritize single-threaded responsiveness or specific instruction sets, AMD is the better fit.
