AMD Ryzen 7 8745HX vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The AMD Ryzen 7 8745HX and Intel Core 7 251E occupy very different positions in the database. The AMD part has a comprehensive set of recorded benchmark results, while the Intel Core 7 251E currently has no benchmark scores listed in the database. This makes a direct score-for-score comparison impossible for the Intel part. However, the AMD Ryzen 7 8745HX can be analyzed against its nearest recorded rivals to establish a performance baseline.

The AMD Ryzen 7 8745HX records an average benchmark score of 60104. This places it at the 92nd percentile of all CPUs in the database. Its nearest rival, the AMD Ryzen 9 7945HX, scores 60099, with a delta of 0%. The Intel Core i9-14900F records 60008, a 0.2% delta. The AMD Ryzen 9 7945HX3D scores 59641, which is 0.8% lower. The Intel Xeon Gold 6338T scores 60572, which is 0.8% higher. The AMD Ryzen 7 8745HX thus sits nearly level with these high-end parts, trailing the Xeon Gold 6338T by less than 1% and leading the Ryzen 9 7945HX3D by a similar margin.

Looking at individual workloads recorded for the AMD Ryzen 7 8745HX, the multithread score is 31517. Single-thread performance is 3879. Integer math results show 100328, while floating-point math reaches 61972. Data compression scores 363759, and data encryption records 21840. Extended instructions produce 27638. Prime number finding scores 159, physics tests reach 1681, and random string sorting records 44494.

The Intel Core 7 251E has no benchmark entries in the database, so its average benchmark score is recorded as 0, and it holds the 50th percentile among all CPUs. Without recorded scores, the head-to-head comparison relies on structural differences and the AMD part's established standing against similar rivals. The database shows the AMD Ryzen 7 8745HX delivering scores that rival high-end desktop and mobile processors, all within a 1% band of the nearest competitors.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 7 8745HX belongs to the 8000 series, built on the Zen 4 architecture with the codename Dragon Range. It uses an 8-core, 16-thread configuration. The process node is 5 nm, fabricated by TSMC. The transistor count is 6,570 million, and the die size is 71 mm². The Intel Core 7 251E uses the Bartlett Lake codename, with a 24-core, 32-thread configuration. It is built on a 10 nm process by Intel, with a die size of 257 mm². No transistor count is recorded for the Intel part.

The AMD part is a mobile segment processor, while the Intel part is a desktop segment processor. The AMD chip uses AMD Socket FL1, and the Intel chip uses Intel Socket 1700. The AMD processor has an unlocked multiplier; the Intel processor does not.

Cache hierarchies differ considerably. The AMD Ryzen 7 8745HX provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Intel Core 7 251E provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. No 3D V-Cache is present on either part.

Memory support also splits the two. The AMD chip supports DDR5 only, with a dual-channel memory bus and a recorded memory bandwidth of 83.2 GB/s. ECC memory is not supported. The Intel chip supports both DDR4 and DDR5, also with a dual-channel bus, and records a higher memory bandwidth of 89.6 GB/s. ECC memory is supported on the Intel part.

PCIe connectivity shows another difference. The AMD Ryzen 7 8745HX provides Gen 5 with 28 lanes from the CPU. The Intel Core 7 251E provides Gen 5 with 16 lanes from the CPU. Integrated graphics differ as well: the AMD part uses Radeon 610M, while the Intel part uses UHD Graphics 770.

Clock speeds favor the Intel part on boost, but the AMD part on base. The AMD chip has a base clock of 3.60 GHz and a boost clock of 5.10 GHz. The Intel chip has a base clock of 2.10 GHz and a boost clock of 5.60 GHz. TDP ratings are 55 watts for the AMD part and 65 watts for the Intel part.

Release timing differs by a few months. The AMD Ryzen 7 8745HX was released on 2025-04-22. The Intel Core 7 251E was released on 2025-01-12. The Intel part has a recorded launch MSRP of $384, while no launch MSRP is recorded for the AMD part. The AMD part number is 100-000001851, and the Intel part number is SRQDUQ657. Both are listed as active production.

The Verdict

The database records a clear performance profile for the AMD Ryzen 7 8745HX: an average benchmark score of 60104, placing it at the 92nd percentile, with nearest rivals all within a 1% band. The Intel Core 7 251E has no recorded benchmark scores and sits at the 50th percentile. From the data alone, the AMD part has established performance credentials, while the Intel part's performance cannot be quantified from recorded measurements.

For users selecting based on recorded performance data, the AMD Ryzen 7 8745HX is the only part with verified scores. Its 8-core, 16-thread Zen 4 design, 5 nm process, and 32 MB L3 cache deliver results that match or slightly exceed several high-end rivals. The Intel Core 7 251E offers a larger core count of 24 cores and 32 threads, a higher boost clock of 5.60 GHz, larger L3 cache of 36 MB, and ECC support, but none of these features have associated benchmark validation in the database.

The AMD part is the choice for anyone relying on measured benchmark data. The Intel part is the choice for those who prioritize the structural specifications listed above, such as core count, ECC memory support, or DDR4 compatibility, but the database provides no performance scores to confirm its behavior.
