Where Each One Wins

The Intel Core 7 251TE dominates in multi-threaded productivity workloads. The Cinebench suite shows a consistent 22.6 to 22.7 percent lead across all versions and both single-core and multi-core tests. This suggests the higher core count (24 vs 6) and larger L3 cache (36 MB vs 16 MB) provide a decisive advantage in rendering and simulation tasks.

The Intel part also wins heavily in math-heavy Passmark tests. Floating point math shows a 46.9 percent lead, integer math a 42.2 percent lead, and prime number finding a 47.9 percent lead. Physics simulation gives Intel a 37.7 percent edge. These results point to strong performance in scientific computing, engineering simulation, and any workload that relies on dense arithmetic.

Data handling also favors Intel. Data compression shows a 20.5 percent advantage, data encryption a 21.6 percent advantage, and random string sorting a 10.5 percent advantage. The multithread test gives Intel a 21.5 percent lead. These wins cover file archiving, disk encryption, and database-style operations.

The AMD Ryzen 5 PRO 8645HS wins in two areas. Passmark extended instructions shows a 25 percent advantage, which covers workloads using specialized instruction sets beyond basic arithmetic. The single-thread test shows an 8.1 percent advantage, indicating that for lightly threaded applications that cannot use many cores, the AMD part delivers higher per-thread throughput. The higher base clock of 4.30 GHz likely contributes to this single-thread win, even though Intel's boost clock is higher.

The Verdict

The data points to a clear split between the two processors. The Intel Core 7 251TE is the stronger performer in nearly every measured category. Its 14 wins out of 17 head-to-head tests, combined with an average benchmark score 34.9 percent higher, make it the choice for workloads that scale across many cores. The 24-core configuration and 36 MB of L3 cache support this pattern.

The AMD Ryzen 5 PRO 8645HS occupies a different position. Its wins in single-thread and extended instruction tests show that it handles per-core efficiency well. The 4 nm process and higher base clock contribute to this. For applications that depend on a few fast threads or specific instruction extensions, the AMD part holds an advantage.

The market segment data adds context. The Intel part is classified as desktop, while the AMD part is mobile. The Intel processor uses the Socket 1700 platform and supports PCIe Gen 5, while the AMD processor uses Socket FP7 and PCIe Gen 4. These platform differences matter for system builders choosing between desktop and mobile designs.

The Intel Core 7 251TE also carries a launch MSRP of $384, which is recorded in the database. The AMD processor has no recorded launch MSRP.

For users prioritizing raw throughput, multi-threaded rendering, heavy math, and data processing, the benchmark results indicate the Intel Core 7 251TE is the stronger option. For users focused on single-thread responsiveness and specialized instruction workloads, the AMD Ryzen 5 PRO 8645HS delivers measurable wins. The percentile rankings confirm this hierarchy: Intel sits at the 88th percentile of all CPUs, AMD at the 82nd percentile.
