AMD Ryzen 5 PRO 8645HS vs Intel Core 5 211E Comparison

The Verdict

The benchmark data divides these two processors by market intent as much as by performance. The AMD Ryzen 5 PRO 8645HS is a mobile processor with 6 cores and 12 threads, built on a 4 nm process, while the Intel Core 5 211E is a desktop chip with 10 cores and 16 threads on a 10 nm process. Across the 17 recorded head-to-head tests, the Intel part wins 14 and the AMD part wins 3. The Intel Core 5 211E leads in every Cinebench test, all with a consistent 3.1 to 3.2 percent advantage, and it dominates in PassMark math workloads, taking data compression by 23.3 percent and floating point math by 31.5 percent. The AMD Ryzen 5 PRO 8645HS counters with a 69.8 percent win in prime number searching, a 72.1 percent win in physics simulation, and a 3.4 percent win in random string sorting.

The database's average benchmark scores place the Intel chip at 37829 versus 30879 for the AMD chip, a gap that mirrors the Intel part sitting at the 86th percentile of all CPUs while the AMD chip sits at the 82nd. For workloads that stress integer math, compression, and sustained multi-threaded rendering, the Intel Core 5 211E is the clear choice. For physics computation and prime number workloads, the AMD Ryzen 5 PRO 8645HS delivers results that are far ahead. The Intel part also shows a slight edge in single-threaded performance, 4006 versus 3858 on PassMark single thread, and 2878 versus 2787 on Cinebench R23 single core. The AMD chip is the only one of the two with a launch MSRP of $221, but that fact is recorded without further context.

Architecture Differences

The AMD Ryzen 5 PRO 8645HS uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. It is a mobile processor with a 45 TDP and uses the AMD Socket FP7. The Intel Core 5 211E uses the Bartlett Lake codename, built on a 10 nm process at Intel with a 257 mm² die and a 65 TDP, using the Intel Socket 1700. The Intel part is a desktop processor.

Cache configurations differ significantly. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 20 MB of shared L3. Both support ECC memory and dual-channel memory buses, but the AMD chip supports DDR5 only with a memory bandwidth of 89.6 GB/s, while the Intel chip supports both DDR4 and DDR5 with a memory bandwidth of 76.8 GB/s. PCIe capabilities also differ: the AMD chip uses Gen 4 with 20 lanes (CPU only), while the Intel chip uses Gen 5 with 16 lanes (CPU only). The integrated graphics are the Radeon 760M for AMD and the UHD Graphics 730 for Intel. Neither processor has an unlocked multiplier.

Clock speeds show the AMD chip with a 4.30 GHz base and 5.00 GHz boost, while the Intel chip has a 2.70 GHz base and 4.90 GHz boost. The Intel chip has 4 more cores and 4 more threads, which partially explains its multi-threaded lead despite the lower base clock.

Head-to-Head Benchmarks

The Intel Core 5 211E wins every Cinebench test. In Cinebench R15 multicore, it scores 2055 versus 1989 for the AMD chip, a 3.2 percent margin. In R15 single core, it scores 289 versus 280, a 3.1 percent margin. The R20 multicore test shows 8563 versus 8291, again 3.2 percent, and R20 single core shows 1208 versus 1170, again 3.1 percent. The R23 multicore test has the Intel chip at 20389 versus 19742, a 3.2 percent gap, and R23 single core at 2878 versus 2787, a 3.2 percent gap. These consistent margins indicate a uniform single-thread and multi-thread advantage for the Intel chip across the Cinebench suite.

The largest Intel wins appear in PassMark math tests. Floating point math shows the Intel chip at 66402 versus 45481 for the AMD chip, a 31.5 percent lead. Data compression shows 346757 versus 265826, a 23.3 percent lead. Integer math shows 88117 versus 72740, a 17.5 percent lead. The data encryption test shows a narrow 3.1 percent Intel lead at 17938 versus 17387. Extended instructions show a 1.8 percent Intel lead at 21592 versus 21212. PassMark multithread shows 23833 versus 23569, a 1.1 percent Intel lead. PassMark single thread shows 4006 versus 3858, a 3.7 percent Intel lead.

The AMD Ryzen 5 PRO 8645HS wins three tests, two by massive margins. In PassMark physics, it scores 1208 versus 702 for the Intel chip, a 72.1 percent lead. In PassMark find prime numbers, it scores 73 versus 43, a 69.8 percent lead. In PassMark random string sorting, it scores 35472 versus 34308, a 3.4 percent lead. These results show that the AMD chip has a strong advantage in workloads that rely on specific instruction patterns rather than raw core count.

The overall win tally is 14 for Intel and 3 for AMD. The average benchmark score difference is 37829 versus 30879, which corresponds to a 22.5 percent higher average score for the Intel chip. The Intel chip's percentile rank of 86 versus 82 for the AMD chip places it higher in the global CPU distribution.

Where Each One Wins

The Intel Core 5 211E wins in all rendering and encoding workloads represented by the Cinebench suite. Its 3.2 percent lead in R23 multicore and 3.2 percent lead in R23 single core indicate that it is uniformly faster in both lightly threaded and heavily threaded rendering tasks. The PassMark math results confirm that the Intel chip is far stronger in floating point operations, with a 31.5 percent lead, and in integer operations, with a 17.5 percent lead. Data compression is another clear Intel win at 23.3 percent, which makes it suitable for database workloads, file archiving, and similar data movement tasks. The encryption test shows a smaller 3.1 percent Intel lead, but it still favors the Intel part.

The AMD Ryzen 5 PRO 8645HS wins in two specialized compute patterns. The 72.1 percent lead in PassMark physics indicates a very strong performance in simulation workloads that depend on the specific instruction set of the Zen 4 architecture. The 69.8 percent lead in prime number searching points to a similar advantage in cryptographic and number-theoretic tasks. The random string sorting win of 3.4 percent is modest but shows that the AMD chip is not universally behind in data manipulation tasks. The AMD chip also has a higher boost clock at 5.00 GHz versus 4.90 GHz, which likely contributes to its single-thread wins in those specific tests, even though the Intel chip wins the PassMark single thread test overall at 4006 versus 3858.

For workloads that use many cores, the Intel chip has a structural advantage with 10 cores versus 6, and that shows in the multithread test at 23833 versus 23569 and in the multicore Cinebench tests. For workloads that use few cores but require high per-core throughput, the Intel chip still leads in most single-thread tests, but the AMD chip wins the physics and prime number tests by wide margins. The choice depends on whether the workload uses general math operations, where Intel excels, or specialized instruction sequences, where AMD excels.
