Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i7-12800HX uses the Alder Lake architecture, specifically the Alder Lake-HX codename, built on a 10 nm process at Intel's foundry. It offers 16 cores and 24 threads, with a base clock of 2000 MHz and a boost clock of 4.8 GHz. The silicon measures 215 mm². Cache is organized as 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3.

The AMD Ryzen 7 7745HX uses the Zen 4 architecture under the Dragon Range codename, fabricated by TSMC on a 5 nm process. It has 8 cores and 16 threads, with a base clock of 3.6 GHz and a boost clock of 5.1 GHz. The die is considerably smaller at 71 mm², and the transistor count is recorded at 6,570 million. L1 cache is 64 KB per core, L2 is 1 MB per core, and L3 is larger at 32 MB shared.

Memory support separates the two as well. The Intel part supports both DDR4 and DDR5 memory in a dual-channel configuration. The AMD part supports only DDR5, also dual-channel, with a recorded memory bandwidth of 83.2 GB/s. ECC memory is supported on the AMD processor but not on the Intel chip. PCIe connectivity differs: Intel provides Gen 5 with 20 lanes (CPU only), while AMD provides Gen 5 with 28 lanes (CPU only).

Integrated graphics also diverge. Intel includes UHD Graphics 770, while AMD includes Radeon 610M. Both processors have unlocked multipliers and are marked as Active in production status. The Intel part launched on 2022-05-09, while the AMD part launched on 2023-01-03. The Intel processor carries the part number SRLGL, and the AMD chip uses the part number 100-000000721. The AMD processor uses the Socket FL1, while Intel uses the BGA 1964 socket.

Where Each One Wins

The benchmark data points to distinct use-case advantages. The Intel Core i7-12800HX is the choice for heavily multithreaded workloads that can use all available cores. Its 16-core, 24-thread configuration drives the 14.5% lead in 3dmark_max_threads and the 21.7% lead in Cinebench R23 multicore. Floating-point math, which is critical for scientific computing, rendering, and simulation, shows a 27.7% Intel advantage. Integer math also favors Intel by 4%, and physics calculations give Intel a 2.7% edge. Data compression is essentially tied, with Intel ahead by just 1.1%.

The AMD Ryzen 7 7745HX wins where single-thread performance and efficiency per core matter. The 5.1 GHz boost clock contributes to wins in Cinebench R15 single-core (11.7% lead), Cinebench R23 single-core (2.1% lead), and passmark_single_thread (6% lead). Prime number finding shows a 30.8% AMD advantage, and extended instruction throughput is 18% higher. Random string sorting, a memory-latency-sensitive test, goes to AMD by 4.5%. Data encryption is 4.3% faster on AMD, and the multithread passmark test goes to AMD by 3.1%, despite Intel having more cores.

The 3dmark results at low thread counts all favor AMD, with the 2-thread test showing a 2.7% lead, the 4-thread test a 4.7% lead, and the 8-thread test a 4.7% lead. This pattern suggests AMD's per-core strength translates into better performance in lightly threaded gaming and application scenarios. The 16-thread 3dmark result is close, with AMD ahead by just 1.3%.

The Verdict

The recorded data presents a nuanced picture. The Intel Core i7-12800HX should be selected for workloads that scale with core count. Its 16 cores and 24 threads deliver a 21.7% advantage in Cinebench R23 multicore and a 14.5% lead in 3dmark_max_threads. Floating-point math is particularly strong, with a 27.7% margin. Users running rendering, scientific computation, or other heavily parallel tasks will find the Intel part consistently ahead.

The AMD Ryzen 7 7745HX is the better choice for single-threaded performance and lightly threaded applications. Its 5.1 GHz boost clock and Zen 4 architecture produce wins across all single-core tests, with the largest margin being 11.7% in Cinebench R15 single-core. The 3dmark results at 2, 4, and 8 threads all favor AMD, suggesting a smoother experience in games and everyday applications that do not fully utilize 16 cores. The 30.8% lead in prime number finding and 18% lead in extended instructions also point to strengths in specific computational tasks.

The overall average scores are close, with Intel at 33875 and AMD at 33091, a difference of roughly 2.4%. The percentile rankings are nearly identical at 84 and 83. The decision comes down to workload profile: choose Intel for maximum multi-threaded throughput, choose AMD for per-core speed and efficiency in lightly threaded tasks. The AMD part's 32 MB of L3 cache and ECC support may also matter for specific professional use cases, while Intel's support for DDR4 provides flexibility for older memory platforms. Both are active mobile processors with unlocked multipliers, so overclocking potential exists, though the database does not record overclocking results.
