Where Each One Wins

The AMD Ryzen 7 8745HX is the stronger performer in workloads that depend on instruction-level efficiency and memory-bound operations. Its 62.8% lead in extended instructions indicates better handling of SIMD-style workloads, which matters for multimedia encoding, scientific code, and certain compression algorithms. The 13.6% advantage in prime number finding and the 12.2% edge in random string sorting reinforce a pattern of strong per-core execution. Data compression, where AMD leads by 8.8%, and single-thread performance, where it leads by 8.7%, make the 8745HX a solid choice for responsiveness in lightly threaded applications. The 5% multithread win, despite Intel's higher core count, shows that the Zen 4 architecture scales efficiently in the 8745HX.

The Intel Core 7 251TE claims the math-heavy categories. The 27.6% floating point advantage and the 20.2% integer advantage suggest that the 251TE handles raw arithmetic throughput better, which benefits financial modeling, engineering simulations, and other number-crunching tasks. The 13.3% physics score lead points to an edge in physics simulation workloads commonly found in engineering and scientific tools. The narrow 1.5% encryption win shows a slight advantage in cryptographic workloads. For users whose primary load is dense arithmetic rather than latency-sensitive single-thread work, the Intel part delivers measurable gains.

The use-case split is therefore clear. The AMD Ryzen 7 8745HX suits general productivity, development, and mixed workloads where single-thread latency and instruction efficiency dominate. The Intel Core 7 251TE suits compute-heavy scenarios that stress floating point and integer pipelines, where its raw arithmetic throughput translates into higher scores.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Ryzen 7 8745HX has 8 cores and 16 threads, while the Intel Core 7 251TE has 24 cores and 32 threads. Base clocks are 3.60 GHz for AMD and 1.40 GHz for Intel; boost clocks are 5.10 GHz for AMD and 5.40 GHz for Intel. The AMD part has a TDP of 55, while the Intel part is rated at 45. The AMD chip uses the AMD Socket FL1, while the Intel chip uses the Intel Socket 1700.

Memory support differs as well. The AMD processor supports DDR5 only, while the Intel processor supports both DDR4 and DDR5. Both use dual-channel memory buses, but the recorded memory bandwidth is 83.2 GB/s for AMD and 89.6 GB/s for Intel. ECC memory is supported by the Intel chip but not the AMD chip. PCIe lane counts also differ: the AMD part provides Gen 5 with 28 lanes (CPU only), while the Intel part provides Gen 5 with 16 lanes (CPU only).

The AMD Ryzen 7 8745HX has an unlocked multiplier, while the Intel Core 7 251TE does not. The integrated graphics differ, with the AMD part using Radeon 610M and the Intel part using UHD Graphics 770. The market segment also separates them: the AMD chip is listed as Mobile, while the Intel chip is listed as Desktop. The Intel processor has a recorded launch MSRP of $384. The AMD processor has no launch MSRP recorded in the database. Production status is Active for both.

Architecture Differences

The AMD Ryzen 7 8745HX belongs to the 8000 series and uses the Zen 4 architecture under the Dragon Range codename. The process node is 5 nm, fabricated by TSMC, with 6,570 million transistors on a 71 mm² die. The Intel Core 7 251TE uses the Bartlett Lake codename under the Core 7 generation, with a 10 nm process node fabricated by Intel. Its die size is 215 mm², and no transistor count is recorded in the database.

Cache configurations differ substantially. The AMD processor provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Intel processor provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 36 MB of shared L3 cache. The larger per-core cache on the Intel part may contribute to its floating point and integer math wins, while the AMD part's smaller die and 5 nm process enable its higher base clock and efficiency in single-thread tasks.

The release dates place the Intel part earlier, with a recorded release date of 2025-01-12, while the AMD part follows with a release date of 2025-04-22. The part numbers are 100-000001851 for AMD and SRQAXQ5ZG for Intel. The AMD processor is a mobile part with 28 PCIe Gen 5 lanes, while the Intel processor is a desktop part with 16 PCIe Gen 5 lanes. These architectural choices align with their respective market positions: the AMD chip targets high-performance mobile systems, and the Intel chip targets desktop platforms with broader memory compatibility, including DDR4 support and ECC capability.
