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

Where Each One Wins

The benchmark data splits these two processors into clearly defined roles. The AMD Ryzen 5 PRO 8640U wins 14 of 17 head-to-head comparisons, while the Intel Core i7-14701TE takes 3. The AMD part dominates general computing, single-threaded workloads, and most productivity tasks. The Intel part wins in three specialized areas: prime number finding, floating-point math, and physics simulations.

The AMD Ryzen 5 PRO 8640U shows its strength in single-threaded performance with a 41.5% advantage in PassMark single-thread testing. It also leads by 41.1% in random string sorting, which indicates superior memory access patterns and cache handling. Data compression favors AMD by 18.3%, and integer math goes to AMD by 13.8%. The encryption workload shows the largest gap for AMD at 35.4%, with extended instruction performance trailing at 33.3% ahead.

The Intel Core i7-14701TE counters in physics simulation with a 38% lead, prime number calculation with a 45.5% lead, and floating-point math with a 9.9% lead. These wins point to workloads that rely on raw arithmetic throughput rather than memory latency or branch prediction. The physics score of 1860 against 1154 represents the second-largest margin in either direction.

For typical desktop use, the AMD processor delivers faster response in single-core tasks, which affects application launch times and lightly threaded software. The Intel processor shows its advantage in mathematically intensive simulations and number-crunching loops. The data suggests AMD for general productivity and Intel for specialized computational workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 PRO 8640U uses Zen 4 architecture on a 4 nm TSMC process, while the Intel Core i7-14701TE uses Raptor Lake architecture on Intel's 10 nm process. AMD integrates 25,000 million transistors on a 178 mm² die, while Intel's die measures 257 mm² with transistor count not recorded in the database.

Core configurations differ significantly. The AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 16 threads. Despite having fewer cores, the AMD processor achieves higher multi-threaded scores in most tests. Clock speeds tell part of the story: AMD boosts to 4.90 GHz from a 3.50 GHz base, while Intel boosts to 5.20 GHz from a 2.10 GHz base. Intel's higher boost clock does not translate into benchmark wins in most cases.

Cache layouts reflect different strategies. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel uses 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. Intel's larger L3 cache (33 MB versus 16 MB) does not overcome AMD's architectural efficiency in most workloads. The larger cache likely contributes to Intel's physics and floating-point wins, where data residency matters.

Memory support shows another divergence. AMD supports DDR5 only with dual-channel access and 89.6 GB/s bandwidth. Intel supports both DDR4 and DDR5 with dual-channel access, though bandwidth is not recorded. Both support ECC memory. AMD uses PCIe Gen 4 with 20 lanes, while Intel uses PCIe Gen 5 with 16 lanes.

The integrated graphics differ: AMD uses Radeon 760M, Intel uses UHD Graphics 770. AMD's socket is FP7 for mobile platforms, while Intel uses Socket 1700 for desktop. The AMD part carries a 28 W TDP, while Intel carries a 45 W TDP. Neither processor has an unlocked multiplier. Release dates show AMD in April 2024 and Intel in June 2024.

Head-to-Head Benchmarks

The Cinebench suite shows consistent AMD dominance. In Cinebench R15 multicore, AMD scores 2014 against Intel's 1716, a 17.4% lead. The single-core test shows the same margin at 17.4% with scores of 284 versus 242. Cinebench R20 multicore gives AMD 8392 against 7154, a 17.3% lead, with single-core at 1184 versus 1010 for another 17.2% margin. Cinebench R23 follows the pattern: AMD leads 19982 to 17035 in multicore (17.3%) and 2821 to 2405 in single-core (17.3%).

PassMark results show wider swings. The AMD processor leads PassMark multithread by 13.7% (22795 versus 20042) and single-thread by 41.5% (3732 versus 2637). Data compression goes to AMD at 260925 versus 220520, an 18.3% margin. Data encryption shows AMD at 15843 versus 11699, a 35.4% advantage. Extended instructions favor AMD by 33.3% (19130 versus 14354). Integer math gives AMD 74875 against 65792, a 13.8% lead. Random string sorting favors AMD by 41.1% (32114 versus 22760).

The Intel wins are concentrated but decisive. Prime number finding shows Intel at 143 versus AMD's 78, a 45.5% margin. Physics simulation gives Intel 1860 against 1154, a 38% lead. Floating-point math goes to Intel at 50219 versus 45265, a 9.9% advantage. These three wins represent 17.6% of the head-to-head tests.

The average benchmark score in the database places AMD at 30254 against Intel's 26013. AMD sits at the 81st percentile of all CPUs, while Intel sits at the 78th. AMD's nearest rivals include the AMD Ryzen 7 2700X (0.1% behind), AMD Ryzen 7 7736U (0.4% ahead), AMD Ryzen 5 7640HS (0.4% ahead), and Intel Core i9-11980HK (0.6% ahead). Intel's nearest rivals include the AMD Ryzen AI 5 340 (0.1% behind), AMD Ryzen 5 8640HS (0.4% ahead), AMD Ryzen 5 PRO 5655GE (0.5% behind), and AMD Ryzen 5 8540U (0.7% ahead).

The Verdict

The data points to the AMD Ryzen 5 PRO 8640U as the stronger overall processor. It wins 14 of 17 benchmarks, holds a 16.2% advantage in average benchmark score (30254 versus 26013), and ranks higher in the percentile distribution (81st versus 78th). The single-threaded performance gap of 41.5% is substantial and affects most everyday applications.

The Intel Core i7-14701TE serves a narrower role. Its wins in prime number finding, physics simulation, and floating-point math indicate suitability for computational workloads that stress arithmetic units. The 45.5% margin in prime numbers and 38% margin in physics are large enough to matter for dedicated number-crunching tasks. However, these wins do not offset the broad AMD advantage in general computing.

For users running mixed workloads, the AMD processor provides better balanced performance. For users running physics simulations or heavy floating-point calculations, the Intel processor's specialized strengths become relevant. The AMD part achieves its results with a lower TDP (28 W versus 45 W) and fewer cores (6 versus 8), which highlights architectural efficiency.

The benchmark data does not support a recommendation for the Intel part outside its three winning categories. The AMD processor leads in every Cinebench test, all PassMark productivity metrics, and the overall average score. The Intel processor's higher boost clock of 5.20 GHz and larger 33 MB L3 cache do not translate into general performance advantages.
