AMD Ryzen 7 PRO 8840U vs Intel Core 9 273PE Comparison

The AMD Ryzen 7 PRO 8840U and the Intel Core 9 273PE occupy different corners of the processor market, and the benchmark data reflects that split clearly. The AMD part is a mobile-focused chip built for efficiency, while the Intel part is a desktop processor aimed at sustained throughput. Across all 17 recorded head-to-head benchmarks, the Intel Core 9 273PE takes every single win. The AMD Ryzen 7 PRO 8840U does not win a single test in the comparison, yet its strengths appear in its power envelope and platform features rather than raw performance scores.

Where Each One Wins

The Intel Core 9 273PE wins in every measured category, but the margins vary dramatically. In single-threaded workloads, the Intel chip is only marginally ahead: the PassMark single-thread score shows Intel at 3650 against AMD at 3641, a delta of just 0.2 percent. This near-tie indicates that for lightly threaded tasks like everyday office productivity or web browsing, the two processors are effectively indistinguishable. The Cinebench R15 single-core test tells a different story, however, with Intel scoring 445 versus AMD's 288, a 35.3 percent gap. This discrepancy suggests the Intel chip's higher boost clock plays a larger role in some single-core workloads than others.

The Intel Core 9 273PE shows its largest advantages in multi-threaded and math-heavy workloads. The PassMark physics test shows Intel at 3120 versus AMD's 1174, a 62.4 percent lead. Similarly, the PassMark find prime numbers test shows Intel at 203 versus AMD's 76, a 62.6 percent gap. These tests reward the Intel chip's additional cores and higher thermal headroom. The AMD Ryzen 7 PRO 8840U, with its 28-watt TDP, is designed for thin-and-light laptops where sustained multi-threaded performance is secondary to battery life and thermals.

The AMD processor does not win any benchmark, but its value proposition lies elsewhere. The database shows the AMD chip has an 83rd percentile ranking among all CPUs, while the Intel chip sits at the 90th percentile. The average benchmark score for AMD is 32233, which places it near the Intel Core i9-11900 at 32226 and the Intel Core i5-14400F at 32279. This indicates the AMD chip punches near desktop-class levels for its power class, even if it cannot match the Intel Core 9 273PE's raw output.

Architecture Differences

The two chips come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 8840U uses the Zen 4 architecture under the Hawk Point codename, fabricated on a 4 nm process at TSMC. It packs 25,000 million transistors into a 178 mm² die. The Intel Core 9 273PE uses the Bartlett Lake codename on a 10 nm process at Intel, and the database does not record transistor count or die size for this part.

Core counts diverge significantly. The AMD chip has 8 cores and 16 threads, while the Intel chip has 12 cores and 24 threads. This 50 percent advantage in core count directly explains the Intel chip's dominance in multi-threaded benchmarks. The cache hierarchy also differs. AMD provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and a much larger 36 MB of shared L3 cache. The Intel chip's larger L3 cache helps with data-heavy workloads that benefit from more on-chip storage.

Process technology separates the two as well. The AMD chip's 4 nm process from TSMC is more advanced than Intel's 10 nm process, which partly explains why AMD achieves competitive single-thread scores despite a lower boost clock of 5.10 GHz versus Intel's 5.70 GHz. The AMD chip also uses a smaller socket, AMD Socket FP7, compared to Intel's Socket 1700, reflecting its mobile orientation.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern across all three versions. In Cinebench R15 multicore, Intel scores 3153 against AMD's 2041, a 35.3 percent lead. The single-core variant shows Intel at 445 versus AMD's 288, the same 35.3 percent delta. Cinebench R20 multicore shows Intel at 13140 against AMD's 8506, again 35.3 percent. Cinebench R20 single-core shows Intel at 1855 versus AMD's 1200. Cinebench R23 multicore shows Intel at 31288 versus AMD's 20254, and Cinebench R23 single-core shows Intel at 4417 versus AMD's 2859. Every Cinebench test records the identical 35.3 percent delta, indicating a uniform scaling factor across the entire suite.

The PassMark results show more varied margins. Data compression shows Intel at 405885 versus AMD's 272664, a 32.8 percent lead. Data encryption shows Intel at 22719 versus AMD's 16441, a 27.6 percent gap. Extended instructions show Intel at 24630 versus AMD's 19132, a 22.3 percent difference. Floating point math shows Intel at 107884 versus AMD's 50746, a 53 percent lead. Integer math shows Intel at 139410 versus AMD's 88339, a 36.6 percent gap. Multithread shows Intel at 36810 versus AMD's 23850, a 35.2 percent lead. Random string sorting shows Intel at 45098 versus AMD's 33109, a 26.6 percent gap.

The two largest margins appear in physics and prime number finding. The physics test shows Intel at 3120 versus AMD's 1174, a 62.4 percent gap. The prime number test shows Intel at 203 versus AMD's 76, a 62.6 percent gap. These tests are heavily dependent on integer throughput and cache behavior, where the Intel chip's extra cores and larger L3 cache shine. The smallest margin is in PassMark single-thread, where Intel scores 3650 versus AMD's 3641, a mere 0.2 percent difference. This near-parity in single-threaded PassMark suggests that for many consumer applications, the AMD chip's higher-frequency Zen 4 cores keep it competitive.

Specification Differences

The two processors differ across nearly every major specification. The AMD Ryzen 7 PRO 8840U has 8 cores and 16 threads, while the Intel Core 9 273PE has 12 cores and 24 threads. Base clocks differ substantially: AMD runs at 3.30 GHz, Intel at 2.30 GHz. Boost clocks flip the comparison: AMD reaches 5.10 GHz, Intel reaches 5.70 GHz. The TDP shows the largest split: AMD is rated at 28 watts, Intel at 65 watts. This 37-watt difference explains the Intel chip's ability to sustain higher multi-threaded performance, but it also means the AMD chip fits in much lighter, fanless or low-profile laptop designs.

Memory support differs as well. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity diverges: AMD offers Gen 4 with 20 lanes from the CPU, while Intel offers Gen 5 with 16 lanes. The integrated graphics also differ, with AMD using Radeon 780M and Intel using UHD Graphics 730. The AMD chip launches on a mobile socket (FP7) with part numbers 100-000001317 and 100-000001377, while the Intel chip uses the desktop Socket 1700 with part number SA4QD. The release dates are separated significantly: AMD launched on 2024-04-15, Intel on 2026-03-08. The Intel chip carries a launch MSRP of $549, which the database records but which does not factor into performance analysis here.
