Where Each One Wins

The recorded data shows a clear split in benchmark coverage. The AMD Ryzen Embedded 8645HS has no benchmark entries in the database, which means every measured score belongs to the Intel Core i7-14701E. The Intel chip holds wins across all available tests.

In Cinebench R15, the Intel i7-14701E delivers a multicore score of 2237 and a single-core score of 315. In Cinebench R20, it scores 9321 multicore and 1315 single-core. In Cinebench R23, it reaches 22195 multicore and 3133 single-core. These results indicate strong performance in both heavily threaded and lightly threaded workloads.

The Passmark suite shows the Intel chip winning in every category. It scores 282939 in data compression, 14862 in data encryption, 18528 in extended instructions, 176 in find prime numbers, 61873 in floating point math, 81325 in integer math, 26112 in multithread, 2399 in physics, 29158 in random string sorting, and 4305 in single thread. The single thread score appears twice in the recorded data, confirming consistency.

For use-case analysis, the Intel chip demonstrates capability in multi-core rendering via the Cinebench scores. The Passmark integer and floating point math results suggest solid general computation. The data compression score of 282939 points to strong archive and file-handling performance. The encryption score of 14862 indicates decent security workload capability.

The AMD chip, lacking any recorded benchmarks, cannot be assigned wins in any measured category. Its advantages, such as the smaller 4 nm process node and lower 45 W TDP, are architectural rather than performance-based in the recorded data. The database shows zero wins for AMD and seventeen benchmark entries for Intel.

The integer math score of 81325 and floating point math score of 61873 show strong arithmetic processing. The data compression score of 282939 is the highest recorded Passmark value for this chip.

The AMD chip's lack of recorded benchmarks means no direct numerical comparison can be made. The database shows zero wins for AMD and seventeen recorded scores for Intel. Any claims about AMD performance would require additional data not present in the database.

The Verdict

The recorded data supports a clear choice for the Intel Core i7-14701E when benchmark performance is the primary criterion. The Intel chip has all seventeen recorded benchmark scores, an average benchmark score of 33206, and sits in the 83rd percentile of all CPUs. The AMD Ryzen Embedded 8645HS has no recorded benchmarks, a percentile rank of 50, and an average benchmark score of 0.

For multi-threaded rendering work, the Intel chip's Cinebench R23 multicore score of 22195 indicates strong capability. Its Passmark multithread score of 26112 and integer math score of 81325 support use in compute-heavy tasks. The data compression score of 282939 suggests good performance in archiving and data handling workloads.

The Intel chip also shows consistency across single-thread tests. The Cinebench R23 single-core score of 3133 and Passmark single thread score of 4305 indicate solid responsiveness for lightly threaded applications.

The AMD chip offers architectural advantages that are not reflected in benchmark scores. Its 4 nm process node from TSMC, 45 W TDP, and 89.6 GB/s memory bandwidth are recorded specifications. The smaller die size of 178 mm² and higher transistor count of 25,000 million suggest efficiency potential. The base clock of 4.30 GHz is notably higher than Intel's 2.60 GHz, which could benefit workloads that run at sustained base frequencies.

The Intel chip counters with a higher boost clock of 5.40 GHz, more L3 cache at 33 MB, and PCIe Gen 5 support. The dual memory support for DDR4 and DDR5 provides flexibility in system design. The larger L2 cache of 2 MB per core and L1 cache of 80 KB per core may help memory-latency-sensitive tasks.

For a system builder prioritizing measured performance, the Intel Core i7-14701E is the data-backed choice. Its benchmark coverage and percentile ranking provide concrete evidence of capability. The AMD Ryzen Embedded 8645HS remains a viable option for low-power or mobile embedded designs where the 45 W TDP and smaller process node are advantages, but its performance profile is unquantified in the database.
