The Verdict

The data paints a clear picture: the AMD Ryzen 9 8945HS is the better all-round performer for most mobile workloads, taking 11 of 15 head-to-head tests. Its wins are decisive in several areas, including a 63.8% margin in Cinebench R15 multicore and a 70.6% margin in extended instructions. Users who prioritize compression, encryption, integer math, multithreaded throughput, and data sorting should choose the AMD chip without hesitation.

The Intel Core i7-13705H, however, is not a straightforward loser. It wins Cinebench R23 single-core by 20.1%, PassMark physics by 22.7%, and prime number finding by 20.7%. These wins point to specific strengths in single-threaded rendering tasks and physics calculations. The Intel chip also holds a higher average benchmark score of 32076 versus 31074, indicating that its wins come in workloads that carry more weight in the aggregate.

For buyers, the choice depends on workload composition. If the primary tasks involve content creation, data compression, encryption, or general multithreaded productivity, the Ryzen 9 8945HS is the stronger pick. If the workload leans toward physics simulation, single-threaded rendering, or prime-number computation, the Core i7-13705H offers measurable advantages. Both chips sit at the same 82nd percentile, so neither represents a class-leading outlier; the decision rests on which specific tasks matter more.

Head-to-Head Benchmarks

The AMD Ryzen 9 8945HS dominates the multithreaded landscape. In Cinebench R15 multicore, it scores 2640 against Intel's 1612, a 63.8% lead. The gap narrows in Cinebench R23 multicore, where AMD scores 16795 versus 15998, still a 5% win. PassMark multithread shows AMD ahead by 21.7% with 29780 against 24460. Integer math goes to AMD with a 17.8% edge, scoring 101226 versus 85927. Data compression favors AMD at 356508 versus 273720, a 30.2% margin, and data encryption shows AMD winning by 30.6% with 21323 against 16324. Extended instructions deliver AMD's largest win, 26964 versus 15810, a 70.6% gap. Random string sorting also goes to AMD by 47.5%, with scores of 43202 and 29285 respectively.

The Intel Core i7-13705H claims its wins in more specialized areas. Cinebench R23 single-core sees Intel scoring 2258 against AMD's 1805, a 20.1% advantage. PassMark physics shows Intel ahead by 22.7%, scoring 1854 versus 1434. Prime number finding favors Intel by 20.7%, with scores of 116 and 92. Floating point math goes narrowly to Intel, 63064 versus 61821, a 2% margin.

Single-threaded performance overall favors AMD. PassMark single-thread shows AMD at 3850 versus 3483, a 10.5% win. Cinebench R15 single-core also goes to AMD, 281 against 227, a 23.8% margin. These results indicate that Intel's single-core win in Cinebench R23 is an outlier rather than a pattern, while AMD's single-thread advantage appears across multiple tests.

The overall win count of 11 for AMD and 4 for Intel reflects the breadth of AMD's dominance. However, the Intel chip's higher average benchmark score suggests that its four wins carry substantial weight in the database's aggregate metric.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen 9 8945HS has 8 cores and 16 threads, while the Intel Core i7-13705H has 14 cores and 20 threads. Base clocks differ significantly: AMD runs at 4.00 GHz, Intel at 2.40 GHz. Boost clocks are closer, with AMD at 5.20 GHz and Intel at 5.00 GHz.

Cache configurations diverge sharply. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3. The larger L3 cache on Intel may contribute to its single-core Cinebench R23 win.

Memory support differs: AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses. AMD lists a memory bandwidth of 89.6 GB/s; the database does not record a bandwidth figure for Intel. Neither processor supports ECC memory.

PCIe capabilities differ. AMD uses PCIe Gen 4 with 20 lanes, while Intel uses PCIe Gen 5 with 8 lanes. The integrated graphics also differ: AMD has a Radeon 780M, while Intel has Iris Xe Graphics 96EU.

The process nodes are distinct. AMD uses a 4 nm process from TSMC, while Intel uses a 10 nm process from its own foundry. The die sizes reflect this: AMD measures 178 mm², Intel measures 257 mm². The database records 25,000 million transistors for AMD but no transistor count for Intel.

The Intel chip has a launch MSRP of $502, while the database does not list a launch MSRP for the AMD chip. Both processors use different sockets: AMD uses AMD Socket FP8, Intel uses Intel BGA 1744. Both are mobile segments, have active production status, and have locked multipliers.

Architecture Differences

The AMD Ryzen 9 8945HS belongs to the 8000 series, using Zen 4 architecture under the codename Hawk Point. It is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The chip's 8 cores and 16 threads all use the same Zen 4 design, with 16 MB of shared L3 cache.

The Intel Core i7-13705H belongs to the Core 13th Gen series, using Raptor Lake architecture under the codename Raptor Lake-H. It is built on a 10 nm process at Intel with a 257 mm² die size. The chip's 14 cores and 20 threads use a hybrid design, combining performance and efficiency cores, with 24 MB of shared L3 cache.

The process node difference is substantial: 4 nm versus 10 nm. This explains the smaller die size for AMD despite the transistor count being recorded only for AMD. The AMD chip's higher base clock of 4.00 GHz versus Intel's 2.40 GHz reflects the efficiency of the smaller process node, while Intel compensates with more cores and a larger cache pool.

Memory architecture differs: AMD supports only DDR5, while Intel supports both DDR4 and DDR5. AMD lists a memory bandwidth of 89.6 GB/s, while no bandwidth figure is recorded for Intel. PCIe generation also differs, with AMD on Gen 4 and Intel on Gen 5, though AMD offers more lanes at 20 versus Intel's 8.

The integrated graphics differ as well: AMD uses Radeon 780M, Intel uses Iris Xe Graphics 96EU. Neither processor supports ECC memory, and both have locked multipliers. The release dates differ by roughly 11 months, with Intel launching in January 2023 and AMD in December 2023.

Where Each One Wins

The AMD Ryzen 9 8945HS is the clear choice for multithreaded productivity. Its 63.8% lead in Cinebench R15 multicore and 21.7% lead in PassMark multithread indicate strong performance in rendering, video encoding, and compilation workloads. Data compression and encryption tasks favor AMD by 30.2% and 30.6% respectively, making it suitable for file archiving, database operations, and security-related workloads. Integer math runs 17.8% faster on AMD, and random string sorting shows a 47.5% advantage, pointing to strength in data processing and sorting algorithms. Extended instructions, where AMD leads by 70.6%, suggest superiority in specialized computational workloads such as cryptography or scientific computing. Single-threaded performance also favors AMD in most tests, with a 10.5% lead in PassMark single-thread and a 23.8% lead in Cinebench R15 single-core.

The Intel Core i7-13705H wins in specific computational niches. Cinebench R23 single-core shows a 20.1% advantage, indicating that certain single-threaded rendering tasks may run faster on Intel. PassMark physics shows a 22.7% lead, making Intel the better choice for physics simulation in gaming or engineering applications. Prime number finding runs 20.7% faster on Intel, which may matter for certain mathematical or cryptographic workloads. Floating point math is nearly tied, with Intel ahead by just 2%, meaning either chip handles FP-heavy tasks adequately.

The Intel chip also holds a higher average benchmark score of 32076 versus 31074, suggesting that its wins, while fewer, occur in tests that contribute more to the aggregate metric. Users who rely on physics simulation, specific single-threaded renderers, or prime-number computation should favor Intel. Users with mixed workloads that include compression, encryption, integer math, or extensive multithreading should choose AMD, as its 11 wins cover a broader range of common tasks.
