AMD Ryzen 5 PRO 8640U vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall win for the Intel Core i7-14701E, which takes 14 of the 17 head-to-head benchmark comparisons. The AMD Ryzen 5 PRO 8640U manages three wins. Across the Cinebench suite, the Intel part leads by a consistent 10% margin in both single-core and multi-core tests. In Cinebench R23 multi-core, the Intel chip scores 22195 against 19982 for the AMD, a 10% gap. The single-core R23 result is 3133 versus 2821, also a 10% deficit for the AMD part. The same pattern holds in R15 and R20, with every Cinebench test showing a 9.8% to 10% advantage for Intel.

PassMark tests reveal a more nuanced picture. The Intel processor wins the PassMark multithread test 26112 to 22795, a 12.7% lead. The single-thread PassMark score is 4305 versus 3732, a 13.3% advantage. The largest single delta comes in PassMark find prime numbers, where Intel scores 176 against 78, a 55.7% margin. Floating point math also favors Intel heavily: 61873 versus 45265, a 26.8% lead. The data compression workload shows a 7.8% Intel advantage, and integer math shows a 7.9% Intel edge.

The AMD Ryzen 5 PRO 8640U wins three targeted workloads. Data encryption is the closest of these, with AMD at 15843 versus Intel at 14862, a 6.6% margin. Extended instructions favor AMD by 3.2%, with scores of 19130 and 18528. The largest AMD win comes in random string sorting, where AMD scores 32114 against 29158, a 10.1% lead. These three wins indicate AMD retains advantages in specific cryptographic and string-processing workloads, despite trailing in the aggregate compute tests.

Architecture Differences

The two processors come from fundamentally different design families. The AMD Ryzen 5 PRO 8640U uses the Zen 4 architecture under the Hawk Point codename, built on a TSMC 4 nm process with 25,000 million transistors on a 178 mm² die. The Intel Core i7-14701E uses Raptor Lake architecture, codename Raptor Lake-R, built on an Intel 10 nm process with a 257 mm² die. These process differences directly influence power and thermal characteristics. The AMD part carries a 28 TDP, while the Intel part is rated at 65 TDP, more than double.

Core counts differ as well. The AMD chip provides 6 cores and 12 threads, while the Intel chip provides 8 cores and 16 threads. This two-core, four-thread advantage contributes to the Intel lead in multi-threaded benchmarks. Cache hierarchies also differ. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The larger Intel L3 cache, more than double the AMD allocation, helps in workloads with large working sets.

Clock speeds show a trade-off. The AMD base clock is higher at 3.50 GHz, but the Intel boost clock is higher at 5.40 GHz versus 4.90 GHz. The Intel part also supports both DDR4 and DDR5 memory, while the AMD part supports DDR5 only. Both use dual-channel memory buses. The AMD memory bandwidth is listed at 89.6 GB/s; no comparable figure is recorded for Intel. Both processors support ECC memory.

Platform connectivity differs substantially. The AMD part uses PCIe Gen 4 with 20 CPU lanes, while the Intel part uses PCIe Gen 5 with 16 CPU lanes. The AMD socket is AMD Socket FP7, a mobile platform, while Intel uses Socket 1700, a desktop platform. The integrated graphics also differ: AMD uses Radeon 760M, Intel uses UHD Graphics 770. The AMD part is marked as a mobile market segment product, while Intel is desktop. Both parts have locked multipliers and remain in active production.

Where Each One Wins

The Intel Core i7-14701E dominates in raw compute throughput. Every Cinebench test, both single-core and multi-core, goes to Intel by a consistent 10% margin. PassMark multithread, single-thread, physics, floating point math, integer math, prime number finding, and data compression all favor Intel. The physics test shows a 51.9% lead for Intel, second only to the prime number gap. This makes the Intel part the clear choice for rendering, simulation, numerical analysis, and any workload that scales with core count and high boost clocks. The 8-core, 16-thread configuration with a 5.40 GHz boost and 33 MB of L3 cache provides a wide advantage in sustained multi-threaded execution.

The AMD Ryzen 5 PRO 8640U wins in three specific areas. Data encryption shows a 6.6% edge, extended instructions a 3.2% edge, and random string sorting a 10.1% edge. These wins point to strengths in cryptographic operations, specialized instruction sequences, and string manipulation. The AMD part also carries a much lower TDP of 28 versus 65, which makes it suitable for thermally constrained mobile chassis. The higher base clock of 3.50 GHz helps in lighter workloads where boost behavior is less relevant.

The use-case split is clear. For desktop workloads that demand maximum multi-threaded performance, the Intel part delivers. For mobile systems prioritizing efficiency and specific encryption or string workloads, the AMD part holds advantages. The benchmark data does not show any scenario where the AMD part matches Intel in general compute; its wins are confined to the three specialized PassMark subtests.

The Verdict

The benchmark data favors the Intel Core i7-14701E for users who need maximum compute throughput. It wins every Cinebench test, all PassMark math and physics tests, and the multithread and single-thread tests. The 8-core, 16-thread configuration, 5.40 GHz boost clock, and 33 MB of L3 cache support a wide range of demanding desktop workloads. The 10% Cinebench lead across the board and the 12.7% PassMark multithread lead indicate a consistent, broad performance advantage.

The AMD Ryzen 5 PRO 8640U serves a different role. Its 28 TDP makes it suitable for mobile systems where power and thermals matter more than peak performance. Its wins in data encryption, extended instructions, and random string sorting give it a niche in security-related and string-heavy tasks. The higher 3.50 GHz base clock and 4 nm TSMC process provide efficiency advantages. The Intel part is the stronger general-purpose desktop processor; the AMD part is the more efficient mobile option with specific workload strengths.
