AMD Ryzen 7 8840HX vs Intel Core 9 273PE Comparison

Architecture Differences

The AMD Ryzen 7 8840HX and Intel Core 9 273PE present two fundamentally different design philosophies. The AMD part belongs to the 8000 series and uses the Zen 4 architecture under the Dragon Range codename, built on a TSMC 5 nm process with 13,140 million transistors across a dual-die layout of 2x 71 mm². The Intel Core 9 273PE uses the Bartlett Lake codename, built on an Intel 10 nm process. Both processors ship with 12 cores and 24 threads, but the underlying implementations diverge sharply.

Cache organization differs considerably. The AMD chip allocates 64 KB of L1 cache per core and 1 MB of L2 per core, with a shared 64 MB L3 pool. Intel uses a larger L1 at 80 KB per core and a larger L2 at 2 MB per core, but its shared L3 is only 36 MB. This means the AMD processor holds 64 MB of shared cache versus Intel's 36 MB, a difference that shows up in data-heavy workloads. The L1 and L2 per-core capacities favor Intel, while the shared L3 favors AMD.

Memory support also separates the two. AMD supports DDR5 only over a dual-channel bus with 83.2 GB/s of bandwidth. Intel supports both DDR4 and DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth. Intel also enables ECC memory, while the AMD part does not. PCIe connectivity differs as well: AMD offers Gen 5 with 28 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only).

Integrated graphics differ. AMD uses the Radeon 610M, while Intel uses UHD Graphics 730. The AMD processor has an unlocked multiplier and targets the mobile segment, using AMD Socket FL1. Intel's part is locked, targets the desktop segment, and uses Intel Socket 1700. The AMD release date is 2025-04-22, while Intel's is 2026-03-08. The Intel part carries a launch MSRP of $549.

Clock behavior shows a trade-off. AMD runs a 2.90 GHz base clock with a 5.10 GHz boost clock and a 55 W TDP. Intel runs a lower 2.30 GHz base clock but a higher 5.70 GHz boost clock, at a 65 W TDP. The higher boost clock on Intel helps single-threaded scenarios, while the higher base clock on AMD helps sustained all-core loads if power stays within the envelope.

The Verdict

The recorded data points to a split decision based on workload type. The AMD Ryzen 7 8840HX wins 9 of the 13 head-to-head benchmark comparisons, including all three PassMark integer-focused tests, data compression, data encryption, extended instructions, prime number finding, multithread performance, and single-thread performance. The Intel Core 9 273PE wins 4 comparisons: Cinebench R23 multicore, Cinebench R23 singlecore, floating point math, and physics.

For users prioritizing integer workloads, data compression, encryption, and general multithreaded throughput, the AMD chip has the stronger record. For users prioritizing Cinebench render scores, floating point math, and physics simulation, the Intel chip leads.

The AMD part also holds the higher percentile ranking at 94 versus Intel's 90, and its average benchmark score of 71797 far exceeds Intel's 49845. The Intel chip counters with a large single-core Cinebench R23 advantage, a 5.70 GHz boost clock, DDR4 and DDR5 support, and ECC memory. The choice depends on whether the workload leans toward AMD's integer and compression strengths or Intel's floating point and physics strengths.

Head-to-Head Benchmarks

The Cinebench R23 results show a decisive Intel victory in both tests. In multicore, Intel scores 31288 against AMD's 25265, a delta of -19.3% for AMD. In singlecore, Intel scores 4417 against AMD's 1857, a massive -58% delta. This single-core gap is the largest percentage difference in the entire comparison set and aligns with Intel's 5.70 GHz boost clock against AMD's 5.10 GHz.

The PassMark suite tells a different story. AMD wins 8 of the 11 PassMark tests plus the single-thread entries. Data compression shows AMD at 496427 versus Intel's 405885, a 22.3% advantage. Data encryption shows AMD at 29919 versus Intel's 22719, a 31.7% advantage. Extended instructions show AMD at 36527 versus Intel's 24630, a 48.3% advantage. Prime number finding shows AMD at 304 versus Intel's 203, a 49.8% advantage. Random string sorting shows AMD at 57971 versus Intel's 45098, a 28.5% advantage. Multithread shows AMD at 41732 versus Intel's 36810, a 13.4% advantage. Integer math shows AMD at 146506 versus Intel's 139410, a 5.1% advantage. Single-thread PassMark shows AMD at 3958 versus Intel's 3650, an 8.4% advantage.

Intel wins two PassMark tests. Floating point math shows Intel at 107884 versus AMD's 86747, a -19.6% delta for AMD. Physics shows Intel at 3120 versus AMD's 2185, a -30% delta.

The pattern is clear: Intel dominates the Cinebench render workloads and floating point physics, while AMD dominates integer math, encryption, compression, extended instructions, and PassMark's multithread and single-thread metrics. The 9-to-4 win count favors AMD overall, but the Cinebench single-core gap is so large that it cannot be ignored for single-threaded render tasks.

Where Each One Wins

AMD Ryzen 7 8840HX strengths: The data shows AMD leading in integer math by 5.1%, data compression by 22.3%, data encryption by 31.7%, extended instructions by 48.3%, prime number finding by 49.8%, random string sorting by 28.5%, multithread by 13.4%, and PassMark single-thread by 8.4%. These wins cover encryption workloads, compression pipelines, and general integer-heavy processing. The 64 MB shared L3 cache likely supports these results, as larger shared cache helps data-heavy operations. The 94th percentile ranking and average benchmark score of 71797 reinforce the AMD part's overall standing.

Intel Core 9 273PE strengths: The data shows Intel leading in Cinebench R23 multicore by 19.3%, Cinebench R23 singlecore by 58%, floating point math by 19.6%, and physics by 30%. The Cinebench R23 singlecore score of 4417 is the standout result, more than double AMD's 1857. The floating point math score of 107884 and physics score of 3120 indicate strong FPU performance. The higher 5.70 GHz boost clock and 80 KB L1 plus 2 MB L2 per core likely drive these single-thread and floating point wins. Intel also supports both DDR4 and DDR5 memory and ECC, adding flexibility for specific system configurations. The launch MSRP of $549 applies to this part.

The benchmark distribution suggests AMD for integer, encryption, compression, and general multithreaded workloads, and Intel for Cinebench rendering, floating point math, and physics simulation. The overall average benchmark score favors AMD at 71797 versus Intel's 49845, but the Cinebench and physics results show Intel's specialized strengths.
