Architecture Differences

The Intel Core i7-14700HX is built on the Raptor Lake-HX architecture, part of the Core 14th Gen series, and uses a 10 nm process from Intel. It is a mobile-market chip with an Intel BGA 1964 socket and a die size of 257 mm². The AMD Ryzen 9 PRO 5945 uses the Zen 3 architecture, codenamed Vermeer, on a 7 nm process from TSMC, and is a desktop part with an AMD Socket AM4. Its die consists of two 74 mm² chiplets, totaling 148 mm², with 8,300 million transistors.

Cache layouts differ substantially. The Intel chip provides 80 KB of L1 per core and 2 MB of L2 per core, with 33 MB of shared L3. The AMD chip offers 64 KB of L1 per core and 512 KB of L2 per core, but a much larger 64 MB of L3. That larger L3 pool helps AMD in workloads that repeatedly access a sizable working set.

Memory support also splits the two. Intel supports both DDR4 and DDR5 over a dual-channel bus, while AMD supports only DDR4, also dual-channel, with a rated memory bandwidth of 51.2 GB/s. The Intel platform moves to PCIe Gen 5 with 16 CPU lanes, whereas AMD uses PCIe Gen 4 with 20 lanes. The Intel chip has an unlocked multiplier and integrates UHD Graphics 770, while the AMD chip has a locked multiplier and no integrated graphics.

The Intel part is a 55 W TDP mobile processor released in January 2024. The AMD chip is a 65 W desktop processor released in April 2022. Both remain in active production. The Intel part's boost clock reaches 5.50 GHz from a 2.10 GHz base, while the AMD part boosts to 4.70 GHz from a 3.00 GHz base.

Head-to-Head Benchmarks

The benchmark results split into two clear patterns: the Intel Core i7-14700HX dominates most multi-threaded and throughput-oriented tests, while the AMD Ryzen 9 PRO 5945 dominates certain single-thread and specialized workloads.

The Intel chip's largest win is in PassMark floating point math, scoring 93836 against 70291, a 33.5% advantage. It also leads PassMark physics by 27.1% (2252 vs 1772) and Cinebench R15 multi-core by 28.8% (3812 vs 2959). In Cinebench R20 multi-core, Intel leads by 5.9% (13059 vs 12333). PassMark multi-thread goes to Intel by 5.8% (36566 vs 34549), and random string sorting by 11.7% (48544 vs 43447). Data compression favors Intel by 5.3% (438539 vs 416599), integer math by a narrow 1.2% (131296 vs 129768), and single-thread PassMark by 12.8% (3947 vs 3499).

The AMD Ryzen 9 PRO 5945 answers with its own set of wins. Its biggest margin is Cinebench R23 single-core, where it scores 4145 versus 2103, a 49.3% lead. It also wins Cinebench R15 single-core by 29% (417 vs 296), Cinebench R23 multi-core by 16.2% (29366 vs 24595), and PassMark find prime numbers by 27.6% (228 vs 165). Extended instructions go to AMD by 4.9% (27031 vs 25718), and data encryption by a slim 0.8% (26313 vs 26092).

The single-core Cinebench results are notable for their inconsistency with PassMark single-thread. AMD wins all three Cinebench single-core tests by large margins, yet Intel wins PassMark single-thread by 12.8%. This suggests the two workloads stress very different parts of the architecture. Cinebench R23 single-core in particular rewards AMD's higher base clock and Zen 3 efficiency, while PassMark's single-thread test aligns more with Intel's higher boost clock and Raptor Lake IPC.

Overall, Intel wins 11 of the 17 head-to-head tests, AMD wins 6. The Intel chip's average benchmark score is 45953, and the AMD chip's is 47527, putting AMD at the 90th percentile of all CPUs versus Intel's 89th. The AMD part sits near the Intel Core Ultra X9 378H in the database (delta 0.1%), while the Intel part sits near the AMD EPYC 7303 and AMD EPYC 4364P (delta 0%).

Where Each One Wins

The Intel Core i7-14700HX is the stronger choice for compute-heavy, multi-threaded workloads. Its wins in floating point math, physics simulation, data compression, and multi-thread PassMark point to broad throughput advantages. The 33.5% lead in floating point math and 27.1% lead in physics make it well suited for scientific calculations and physics-heavy applications. Its 28.8% lead in Cinebench R15 multi-core reinforces the pattern for legacy multi-threaded rendering tasks. The 11.7% advantage in random string sorting and 5.3% in data compression also make it the better option for data processing pipelines that involve sorting, archiving, or encoding-like tasks. The 12.8% win in PassMark single-thread means it also holds a general desktop responsiveness edge in that specific benchmark.

The AMD Ryzen 9 PRO 5945 wins where its larger L3 cache and higher base clock matter most. The 49.3% lead in Cinebench R23 single-core is the largest margin in the entire comparison, making it the clear pick for lightly threaded workloads that rely on a single core's peak performance. The 29% lead in Cinebench R15 single-core supports that conclusion. Its 16.2% win in Cinebench R23 multi-core shows that in some modern rendering workloads, the AMD part's 64 MB L3 and 12 Zen 3 cores outperform Intel's higher core count. The 27.6% win in find prime numbers points to strength in integer-heavy algorithmic loops, and the 4.9% lead in extended instructions plus 0.8% in data encryption makes it competitive for cryptography and SIMD-heavy code.

The Verdict

The Intel Core i7-14700HX should be chosen by users who prioritize raw throughput across a wide range of multi-threaded tasks. The data shows 11 wins out of 17 head-to-head tests, with large margins in floating point math, physics, and data compression. Its 20 cores, 28 threads, and 5.50 GHz boost clock make it the stronger general-purpose workhorse, especially for mobile workstation users who need a laptop chip that can handle demanding compute loads. The integrated UHD Graphics 770 also removes the need for a discrete GPU in basic display scenarios.

The AMD Ryzen 9 PRO 5945 is the pick for workloads where single-core performance and cache capacity dominate. Its 49.3% lead in Cinebench R23 single-core is emphatic, and its 16.2% win in Cinebench R23 multi-core shows it can still beat the Intel chip in certain modern rendering tests despite having 8 fewer cores. The 64 MB L3 cache and 7 nm TSMC process give it an efficiency and latency advantage that shows up in prime number searches, extended instruction tests, and encryption. Desktop users on Socket AM4 with DDR4 memory will find it a natural fit, and the lack of integrated graphics is irrelevant for systems that already have a discrete GPU.

Neither chip is a universal winner. The database places the AMD part at the 90th percentile of all CPUs with an average score of 47527, just above the Intel part's 89th percentile and 45953 average. The decision hinges on workload mix: Intel for broad multi-threaded throughput in a mobile form factor, AMD for single-core dominance and cache-sensitive desktop workloads.
