AMD Ryzen AI Max+ 395 vs Intel Core Ultra 5 225T Comparison

The AMD Ryzen AI Max+ 395 and Intel Core Ultra 5 225T occupy different corners of the processor market, yet their benchmark data reveals a surprisingly one-sided competition. The AMD part, a 16-core mobile flagship built on the Strix Halo platform, dominates nearly every recorded workload, while the Intel desktop chip, with 10 cores and a higher single-thread clock, carves out a narrow but real niche. The recorded data shows 12 benchmark wins for AMD and 3 for Intel, a split that reflects their divergent design goals more than any fundamental quality gap.

Where Each One Wins

The AMD Ryzen AI Max+ 395 wins across the vast majority of tested workloads, and the margins are often dramatic. In multi-threaded and compute-intensive tasks, the AMD part's 32 threads versus Intel's 10 threads create an insurmountable gap. The data shows wins in Cinebench R15 multi-core, Cinebench R23 multi-core, PassMark data compression, data encryption, extended instructions, floating point math, integer math, multithread, physics, random string sorting, and even the prime number test. The largest single victory comes in PassMark integer math, where AMD leads by 237%. These results indicate that any workload that can use more than a handful of cores will strongly favor the AMD part.

The Intel Core Ultra 5 225T wins in two single-threaded tests: Cinebench R23 single-core by 34.1% and PassMark single-thread by 4.6%. It also edges out AMD in Cinebench R15 single-core, but only by 1.3%, a margin that falls within typical run-to-run variation. The Intel chip's boost clock of 4.90 GHz, compared to AMD's 5.10 GHz, does not explain these wins; rather, the Arrow Lake architecture appears to deliver higher instructions per clock in lightly threaded scenarios. The data suggests that Intel's advantage is real but narrow, confined to applications that are strictly single-threaded and cannot spread work across multiple cores.

The use-case split is clear. For rendering, compilation, data processing, encryption, physics simulation, or any parallel workload, the AMD Ryzen AI Max+ 395 is the superior part by a wide margin. For legacy single-threaded applications, or for users who prioritize maximum performance in a single core, the Intel Core Ultra 5 225T delivers a measurable, though smaller, advantage.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Max+ 395 uses the Zen 5 architecture on a 4 nm TSMC process, with a die size listed as 2x 70.6 mm². It has 16 cores and 32 threads, with 80 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The memory subsystem is LPDDR5X over a quad-channel bus, yielding 256.0 GB/s of bandwidth. The integrated graphics are Radeon 8060S. This is a mobile part, designed for Socket FP11, with a 55 W TDP.

The Intel Core Ultra 5 225T uses the Arrow Lake architecture on a 3 nm TSMC process, with a die size of 243 mm² and 17,800 million transistors. It has 10 cores and 10 threads, with 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3 cache. Memory support is DDR5 over a dual-channel bus, providing 102.4 GB/s of bandwidth. The integrated graphics are Arc Xe-LPG Graphics 16EU. This is a desktop part for Socket 1851, with a 65 W TDP.

The architectural differences explain the benchmark results. AMD's 16 cores with simultaneous multithreading double the thread count to 32, while Intel's 10 cores run without hyperthreading, staying at 10 threads. AMD's L3 cache is 64 MB, three times Intel's 20 MB, and its memory bandwidth is 256.0 GB/s versus 102.4 GB/s, a 2.5x advantage. The process nodes differ, with Intel on 3 nm versus AMD on 4 nm, but the transistor count, 17,800 million for Intel, does not translate into compute dominance because the core configuration and thread count are less favorable for parallel work. The PCIe support also differs: Intel offers Gen 5 with 20 lanes, while AMD provides Gen 4 with 16 lanes, a factor that matters for expansion but not for the recorded CPU benchmarks.

Head-to-Head Benchmarks

The Cinebench results show the core-count effect clearly. In Cinebench R15 multi-core, AMD scores 5463 against Intel's 2214, a 146.7% lead. In Cinebench R23 multi-core, AMD scores 35314 versus 21971, a 60.7% lead. These are massive margins, confirming that the AMD part scales far better across all cores. The single-core results flip the story. In Cinebench R23 single-core, Intel scores 3101 versus AMD's 2044, a 34.1% advantage. In Cinebench R15 single-core, AMD wins by a razor-thin 1.3%, with scores of 316 and 312.

PassMark results reinforce the same pattern with even larger deltas. In data compression, AMD scores 690650 against 233998, a 195.2% lead. Data encryption shows AMD at 35455 versus 18289, a 93.9% lead. Extended instructions favor AMD at 56346 versus 20083, a 180.6% lead. Integer math gives AMD a 237% advantage, with 200665 versus 59543. Floating point math shows AMD at 128682 versus 82751, a 55.5% lead. The multithread test has AMD at 54934 versus 25358, a 116.6% lead. Physics shows AMD at 3481 versus 2053, a 69.6% lead. Random string sorting has AMD at 76177 versus 28774, a 164.7% lead. Even the prime number test, which often favors high single-thread clocks, goes to AMD by 6.7%, with 303 versus 284.

The only Intel wins in PassMark are the single-thread tests. PassMark single-thread has Intel at 4348 versus AMD's 4147, a 4.6% lead. The same result appears twice in the data, under both passmark_single_thread and passmark_singlethread, confirming the consistency. The overall picture is unambiguous: AMD wins 12 of 15 head-to-head benchmarks, and the victories are often by triple-digit percentages, while Intel's wins are small in comparison.

The Verdict

The benchmark data points to a clear conclusion for different user profiles. The AMD Ryzen AI Max+ 395 is the choice for anyone running multi-threaded workloads. Its 32 threads, 64 MB of L3 cache, and 256.0 GB/s of memory bandwidth translate into dominant leads in rendering, data compression, encryption, physics, and integer math. The 95th percentile standing among all CPUs, with an average benchmark score of 77740, places it in the top tier, alongside parts like the Intel Core i9-14900K, which it trails by only 1.7%, and ahead of the AMD Ryzen 9 8945HX by 2%. The mobile form factor with a 55 W TDP makes it a striking option for high-performance laptops that need desktop-class compute.

The Intel Core Ultra 5 225T is the choice for a narrower set of applications. Its 82nd percentile standing, with an average benchmark score of 30468, places it near parts like the Intel Core i9-11980HK, with a 0.2% delta, and the AMD Ryzen 5 7640HS, with a 0.3% delta. It wins single-threaded Cinebench R23 by 34.1% and PassMark single-thread by 4.6%, which makes it suitable for legacy software that uses one core. Its desktop socket, DDR5 support, and Gen 5 PCIe with 20 lanes offer a modern platform for users who prioritize expansion and don't need maximum parallel compute.

For parallel performance, the AMD part is the clear winner. For single-threaded responsiveness, the Intel part has a measurable edge. The data does not support any other conclusion. The AMD Ryzen AI Max+ 395 wins 12 benchmarks, often by huge margins, while the Intel Core Ultra 5 225T wins 3, with only one of those wins exceeding 5%. Users who value multi-core throughput should select AMD. Users who value single-core speed above all else should select Intel, but they should be aware that the AMD part is still competitive in single-threaded tests, losing by only 4.6% in PassMark and 1.3% in Cinebench R15. The overall average benchmark score, 77740 for AMD versus 30468 for Intel, reflects a 2.5x difference in aggregate performance, which is the most direct summary of the data.
