Where Each One Wins

The Intel Core 7 253PE wins in every recorded benchmark category. Its largest advantages appear in floating point math, prime number finding, and physics tests, where deltas exceed -40%. These results indicate strong performance in compute-heavy parallel workloads. The Intel chip also leads in integer math by -38.8%, suggesting solid general-purpose number crunching. The multithread score advantage of -26.7% reflects its higher core and thread count.

The AMD Ryzen 5 PRO 8640HS does not win any recorded benchmark, but its narrowest losses show relative strengths. The random string sorting delta of -7.8% is the closest margin, indicating competitive memory access patterns. The single-thread score delta of -10% shows that the AMD chip is reasonably strong in lightly threaded tasks, even though it still trails. The extended instructions delta of -15.1% also shows a relatively smaller gap, suggesting the AMD processor handles specialized instruction sets better than it handles raw parallel math.

The power characteristics favor the AMD part in another dimension: its 28 watt TDP is less than half of Intel's 65 watt TDP. This makes the AMD processor more suitable for thermally constrained mobile systems, while the Intel chip's higher power envelope aligns with its desktop market segment. The AMD chip's smaller 4 nm process and 178 mm² die with 25,000 million transistors suggest a denser, more power-efficient design.

The Verdict

The benchmark data shows the Intel Core 7 253PE as the faster processor across all measured workloads. Its 17 wins out of 17 comparisons, combined with an average benchmark score of 40,557 versus AMD's 28,478, establishes a clear performance lead. The Intel chip's higher core count, thread count, boost clock, and larger shared L3 cache all contribute to this result. The delta of -27.2% across Cinebench tests indicates a consistent and substantial performance gap in both single-core and multi-core rendering workloads.

The AMD Ryzen 5 PRO 8640HS remains competitive in specific areas despite losing every test. Its narrowest deficits in random string sorting and single-thread performance show that it can approach Intel's results in certain memory-bound and lightly threaded scenarios. Its 28 watt TDP and 4 nm process make it a more power-efficient choice for mobile platforms, and its 80th percentile ranking puts it in the upper range of all CPUs in the database.

The Intel Core 7 253PE is the pick for users prioritizing maximum throughput in parallel compute, rendering, and math-heavy applications. Its 87th percentile ranking and 65 watt TDP indicate a desktop-oriented part designed for sustained performance. The AMD Ryzen 5 PRO 8640HS suits systems where power efficiency and mobile integration take precedence, with its 80th percentile ranking showing solid performance within a lower power envelope. The selection depends on whether the priority is raw speed or efficiency, and the recorded data supports Intel for the former and AMD for the latter.
