AMD Ryzen 5 PRO 8640U vs Intel Core i9-14901E Comparison

The Verdict

The benchmark data presents a clear hierarchy between these two processors. The Intel Core i9-14901E wins 16 of the 17 head-to-head comparisons, with the AMD Ryzen 5 PRO 8640U taking a single victory. The Intel part holds an 86th percentile ranking among all CPUs, while the AMD chip sits at the 81st percentile. The average benchmark score for the Intel Core i9-14901E is 37911, compared to 30254 for the AMD Ryzen 5 PRO 8640U, a gap of roughly 25 percent.

The Intel Core i9-14901E is the appropriate choice for workloads that demand maximum throughput, particularly multi-threaded rendering, physics simulation, and prime number calculations where its lead is substantial. The AMD Ryzen 5 PRO 8640U is a mobile processor with a 28 watt TDP, and the data indicates it should be selected when power efficiency and the integrated Radeon 760M graphics are priorities, though its performance deficit in nearly every measured category is significant. The Intel part is a desktop processor with a 65 watt TDP, which explains its performance advantage but also indicates a different thermal and power envelope.

Architecture Differences

The AMD Ryzen 5 PRO 8640U belongs to the 8000 series and uses the Zen 4 architecture under the Hawk Point codename. It is built on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. The processor has 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. Its cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The memory support is DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth, and it supports ECC memory. The platform uses AMD Socket FP7, and the CPU provides Gen 4 PCIe with 20 lanes. Integrated graphics come from the Radeon 760M. The release date is 2024-04-15.

The Intel Core i9-14901E is part of the Core 14th Gen series and uses the Raptor Lake architecture under the Raptor Lake-R codename. It is built on a 10 nm process at Intel with a die size of 257 mm². The processor has 8 cores and 16 threads, with a base clock of 2.80 GHz and a boost clock of 5.60 GHz. Its cache configuration includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache.

The architectural differences are substantial. The AMD chip uses a smaller 4 nm process node compared to Intel's 10 nm node, and it has fewer cores and threads. The Intel part has more L1 and L2 cache per core, more than double the shared L3 cache at 36 MB versus 16 MB, and a higher boost clock. The AMD chip has a lower TDP at 28 watts versus 65 watts, reflecting its mobile market segment, while the Intel part targets desktop systems. The AMD processor offers more PCIe lanes at Gen 4, while the Intel processor offers fewer lanes but at Gen 5 speed. Both support ECC memory, which is notable for workstation-class usage.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern. In Cinebench R15 multicore, the Intel Core i9-14901E scores 2595 against 2014 for the AMD Ryzen 5 PRO 8640U, a delta of -22.4 percent from AMD's perspective. The single-core R15 test shows 366 versus 284, also a -22.4 percent delta. Cinebench R20 multicore shows 10816 versus 8392, and R20 single-core shows 1526 versus 1184, both at the same -22.4 percent delta. Cinebench R23 multicore shows 25753 versus 19982, and R23 single-core shows 3635 versus 2821, again both at -22.4 percent. The uniformity of this delta across all six Cinebench tests indicates a consistent performance scaling difference between the two chips.

The Passmark suite reveals where the AMD chip manages to compete and where it falls dramatically behind. The AMD Ryzen 5 PRO 8640U wins the extended instructions test with a score of 19130 against 17249 for the Intel part, a delta of 10.9 percent in AMD's favor. This is the only benchmark where AMD takes the lead.

In the other Passmark tests, the Intel Core i9-14901E dominates. The physics test shows the largest gap: 3041 versus 1154, a delta of -62.1 percent. The find prime numbers test shows 189 versus 78, a delta of -58.7 percent. Floating point math shows 81089 versus 45265, a delta of -44.2 percent. Integer math shows 112736 versus 74875, a delta of -33.6 percent. Multithread shows 30298 versus 22795, a delta of -24.8 percent.

Where Each One Wins

The Intel Core i9-14901E is the clear winner in the majority of workloads. Its most dominant performance comes in the Passmark physics test, where it scores 3041 against 1154, a lead of 62.1 percent. This indicates a substantial advantage in workloads that rely on physical simulation and collision detection. The find prime numbers test shows a 58.7 percent lead, suggesting strong integer-heavy algorithmic performance. Floating point math shows a 44.2 percent lead, and integer math shows a 33.6 percent lead, both indicating broad computational superiority.

In rendering workloads, the Cinebench results show a consistent 22.4 percent advantage for the Intel part across R15, R20, and R23, in both single-core and multicore tests. This consistency makes the Intel chip the better option for 3D rendering and content creation tasks that use these benchmarks. The multithread Passmark score shows a 24.8 percent lead, and the physics result reinforces the multi-threaded advantage.

The Intel part also wins in data compression by 9.6 percent, data encryption by 14.7 percent, random string sorting by 17.9 percent, and single-thread performance by 14.3 percent. These are smaller margins but still consistent wins. The Intel chip has more cores, more threads, more L3 cache, and a higher boost clock, all of which contribute to its dominance.

The AMD Ryzen 5 PRO 8640U has exactly one benchmark win: the Passmark extended instructions test, with a 10.9 percent advantage. This suggests that workloads using extended instruction sets, such as advanced SIMD operations, may favor the Zen 4 architecture. However, this single win does not offset the broad performance gap in the other 16 benchmarks.

For use-case planning, the data supports the Intel Core i9-14901E for desktop workloads requiring maximum multi-threaded performance, physics simulation, complex mathematical calculations, and high-throughput computing. The AMD Ryzen 5 PRO 8640U, with its 28 watt TDP, 4 nm process, and mobile socket, is positioned for power-sensitive mobile systems where the extended instructions advantage and the Radeon 760M integrated graphics matter more than raw computational throughput. The Intel chip's 65 watt TDP and desktop socket indicate a system with more thermal headroom and power delivery capacity. The choice between them depends on whether the workload prioritizes the Intel part's broad performance lead or the AMD part's efficiency and specific instruction set strengths.
