AMD Ryzen 7 PRO 8840HS vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The recorded data presents a sharply split picture between the AMD Ryzen 7 PRO 8840HS and the Intel Core Ultra 5 225T. Across the 15 head-to-head benchmark comparisons, Intel secures 8 wins and AMD takes 7, but the margin and character of those victories differ dramatically. The Intel part dominates the newer Cinebench workloads by wide margins, while the AMD part sweeps most PassMark integer, compression, and encryption tests.

The most lopsided result in the entire dataset is Cinebench R23 single-core, where Intel leads by 44.4%. The Intel score of 3101 dwarfs the AMD score of 1724. Cinebench R23 multi-core is nearly as decisive, with Intel at 21971 versus AMD at 14784, a 32.7% advantage. Cinebench R15 single-core also goes to Intel by 13%, with 312 versus 271.5. The only Cinebench test AMD wins is R15 multi-core, where it posts 2458 against Intel's 2214, an 11% lead.

The PassMark suite tells a different story. AMD's largest win is in integer math, where it scores 93342 versus 59543, a 56.8% advantage. Data compression also favors AMD heavily: 311199 versus 233998, a 33% gap. Random string sorting goes to AMD by 31.8%, with 37922 versus 28774. Extended instructions favor AMD by 11%, at 22298 versus 20083. Data encryption is a narrow AMD win, 18838 versus 18289, a 3% margin. PassMark multi-thread also goes to AMD, 26646 versus 25358, a 5.1% lead.

Intel's PassMark wins are concentrated in workloads that appear to favor its architecture. Find prime numbers shows Intel at 284 versus AMD's 84, a 70.4% lead. Floating point math goes to Intel by 32.6%, 82751 versus 55739. Physics testing favors Intel by 34.2%, with 2053 versus 1351. PassMark single-thread goes to Intel by 15.1%, 4348 versus 3692. The overall average benchmark scores reflect these divergent strengths: AMD sits at 39603 with an 87th percentile ranking among all CPUs, while Intel sits at 30468 with an 82nd percentile ranking.

Where Each One Wins

The workload split is clear from the head-to-head data. Intel wins where single-core speed and floating-point throughput matter most. Cinebench R23 single-core and multi-core, Cinebench R15 single-core, PassMark floating point math, PassMark physics, PassMark find prime numbers, and PassMark single-thread all belong to Intel. These are workloads that often respond to high clock speeds and strong per-core instruction throughput. The Intel boost clock of 4.90 GHz and base clock of 2.50 GHz, combined with its 3 nm process, appear to deliver consistent advantages in these tests.

AMD wins in integer-heavy and memory-oriented tasks. Integer math, data compression, random string sorting, extended instructions, data encryption, and PassMark multi-thread all go to AMD. The Ryzen 7 PRO 8840HS also takes Cinebench R15 multi-core. These results suggest AMD's 8 cores and 16 threads, with simultaneous multithreading, handle parallel integer workloads efficiently. The AMD part also carries 16 MB of shared L3 cache and 1 MB of L2 per core, which may explain its strength in compression and sorting tasks that benefit from cache locality.

The benchmark pattern implies that Intel's 10 cores and 10 threads, lacking hyper-threading, still deliver strong multi-core performance in Cinebench R23, but AMD's threading advantage shows up in PassMark multi-thread. Notably, the two CPUs trade wins in ways that do not align simply with core counts or thread counts. Intel has more cores but fewer threads; AMD has fewer cores but more threads. The data indicates that workload type matters more than raw core count in determining the winner.

Architecture Differences

The two processors come from fundamentally different design lineages. AMD uses Zen 4 architecture on a 4 nm TSMC process, with the Hawk Point codename, while Intel uses Arrow Lake architecture on a 3 nm TSMC process, with the Arrow Lake-S codename. AMD's die size is 178 mm² with 25,000 million transistors; Intel's die is larger at 243 mm² but packs fewer transistors, 17,800 million. The transistor density difference reflects the newer 3 nm node used by Intel.

Core and thread configurations differ significantly. AMD provides 8 cores and 16 threads; Intel provides 10 cores and 10 threads. AMD's base clock is 3.30 GHz with a boost of 5.10 GHz; Intel's base clock is 2.50 GHz with a boost of 4.90 GHz. Cache hierarchies also diverge. AMD allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The larger per-core caches on Intel may explain its single-thread dominance in Cinebench R23.

Memory support is DDR5 for both, with dual-channel buses. AMD lists 89.6 GB/s memory bandwidth and supports ECC memory; Intel lists 102.4 GB/s memory bandwidth but does not support ECC. PCIe connectivity also differs: AMD uses Gen 4 with 20 lanes from the CPU, while Intel uses Gen 5 with 20 lanes from the CPU. The integrated graphics are different as well: AMD uses Radeon 780M, while Intel uses Arc Xe-LPG Graphics 16EU. AMD's socket is AMD Socket FP7, and Intel's socket is Intel Socket 1851. AMD's TDP is 28 watts, while Intel's TDP is 65 watts. AMD is a mobile-market part; Intel is a desktop-market part. AMD's release date is 2024-04-15; Intel's release date is 2024-12-31. Neither processor has an unlocked multiplier.

The Verdict

The data supports a straightforward conclusion for buyers who prioritize specific workloads. Intel Core Ultra 5 225T is the stronger choice for tasks that rely on single-core performance and floating-point math. Its 44.4% lead in Cinebench R23 single-core and 32.6% lead in floating-point math are substantial. The 70.4% lead in find prime numbers further reinforces this pattern. For rendering, physics simulation, and other floating-point-heavy applications, Intel has the clear edge in the recorded benchmarks.

AMD Ryzen 7 PRO 8840HS is the stronger choice for integer-heavy workloads and data processing tasks. Its 56.8% lead in integer math, 33% lead in data compression, and 31.8% lead in random string sorting are decisive. The AMD part also wins extended instructions and data encryption, making it a compelling option for database work, compression pipelines, and general productivity tasks. The 5.1% lead in PassMark multi-thread suggests AMD's 16 threads handle mixed parallel workloads well.

The average benchmark scores complicate a simple winner. AMD's 39603 average is higher than Intel's 30468, and AMD ranks at the 87th percentile versus Intel's 82nd. Yet Intel wins the two most recent Cinebench versions by large margins. The data indicates that the average score is pulled up by AMD's strong PassMark results, while Intel's Cinebench dominance reflects a different set of strengths. The choice depends entirely on the target workload.
