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

The recorded data compares the AMD Ryzen 7 PRO 8840U with the Intel Core Ultra 5 225T. AMD's part is a mobile 8-core processor with 16 threads, while Intel's is a desktop 10-core processor with 10 threads. Across the 17 head-to-head benchmark entries, Intel wins 14 and AMD wins 3. The aggregate average benchmark score, however, sits higher for AMD at 32233 versus 30468, and the database percentile ranks are 83 for AMD and 82 for Intel. The headline result is a split: Intel dominates most measured workloads, while AMD takes large wins in a few specific tests.

Head-to-Head Benchmarks

Intel wins every Cinebench comparison. In Cinebench R23 multi-core, Intel scores 21971 against AMD's 20254, a 7.8% advantage. In R23 single-core, Intel scores 3101 against 2859, also 7.8%. The R20 results follow the same pattern: 9227 versus 8506 in multi-core and 1302 versus 1200 in single-core, both 7.8% margins. In R15, Intel leads 2214 to 2041 in multi-core and 312 to 288 in single-core. The R15 single-core margin is 7.7%, while the other five Cinebench comparisons are 7.8%. The consistency of these margins suggests a uniform per-thread advantage for Intel across Cinebench versions.

Passmark single-thread also favors Intel by a larger margin: 4348 versus 3641, or 16.3%. Intel's other wins include data encryption at 18289 versus 16441 (10.1%), extended instructions at 20083 versus 19132 (4.7%), find prime numbers at 284 versus 76 (73.2%), floating point math at 82751 versus 50746 (38.7%), multithread at 25358 versus 23850 (5.9%), and physics at 2053 versus 1174 (42.8%). The prime-number result is the largest single margin in the comparison. The floating-point and physics margins are also substantial, both above 38%.

AMD's three wins are concentrated in integer and data-handling workloads. Integer math scores 88339 versus 59543, a 48.4% lead. Data compression scores 272664 versus 233998, a 16.5% lead. Random string sorting scores 33109 versus 28774, a 15.1% lead. These three wins are large enough to push AMD's aggregate average benchmark score above Intel's despite Intel winning 14 of 17 entries. The Passmark multithread result is closer at 5.9%, and it shows that Intel's 10 cores and 10 threads can outrun AMD's 8 cores and 16 threads in a mixed multithread workload.

Architecture Differences

The two processors use different architectures and process nodes. AMD uses Zen 4 under the Hawk Point codename, built on a 4 nm process at TSMC. Intel uses Arrow Lake under the Arrow Lake-S codename, built on a 3 nm process at TSMC. The Intel die is larger at 243 mm², while the AMD die is 178 mm². Transistor counts go the other way: AMD integrates 25,000 million transistors, Intel integrates 17,800 million.

Core and thread organization differs sharply. AMD has 8 cores and 16 threads, meaning two threads per core. Intel has 10 cores and 10 threads, meaning one thread per core. This gives AMD more concurrent threads despite fewer physical cores.

Cache hierarchies are different. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. Intel has the larger per-core L1/L2 allocations and the larger shared L3.

Memory and I/O features also diverge. Both support DDR5 on a dual-channel bus, but Intel's memory bandwidth is 102.4 GB/s versus AMD's 89.6 GB/s. AMD supports ECC memory, Intel does not. AMD exposes PCIe Gen 4 with 20 lanes, Intel exposes PCIe Gen 5 with 20 lanes. The integrated graphics solutions are different as well: AMD uses Radeon 780M, Intel uses Arc Xe-LPG Graphics 16EU.

Market positioning differs: AMD is a mobile processor on AMD Socket FP7, Intel is a desktop processor on Intel Socket 1851. Release timing differs: AMD's release date is 2024-04-15, Intel's is 2024-12-31. Both are listed as active production parts.

The Verdict

Across the recorded benchmarks, the Intel Core Ultra 5 225T is the broader performer. It wins 14 of 17 head-to-head entries, including all six Cinebench tests, Passmark single-thread, encryption, extended instructions, prime-number search, floating-point math, multithread, and physics. The Cinebench margins are mostly 7.8%, with a 7.7% single-core R15 result, while Passmark single-thread is 16.3% and prime-number search is 73.2%. The AMD Ryzen 7 PRO 8840U wins integer math by 48.4%, data compression by 16.5%, and random string sorting by 15.1%. Those three margins lift AMD's aggregate average score to 32233, above Intel's 30468, and place AMD one percentile point higher at 83 versus 82.

The data points to Intel for Cinebench workloads, floating-point math, encryption, prime-number searches, and single-thread Passmark workloads. It points to AMD for integer math, data compression, and random string sorting. The Intel part is the stronger all-around performer in the recorded head-to-head set, while the AMD part holds specific workload niches and the higher aggregate average score. The verdict is workload-dependent.
