AMD Ryzen AI 9 365 vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The benchmark data reveals a clear split: the AMD Ryzen AI 9 365 dominates integer-heavy and compression workloads, while the Intel Core Ultra 5 225T takes the lead in single-threaded and floating-point tasks. Across the 15 recorded head-to-head comparisons, the AMD part wins 7, and the Intel part wins 8, making the overall outcome nearly even but with very different strengths.

The most decisive AMD victory comes in PassMark integer math, where the Ryzen AI 9 365 scores 101,831 against the Core Ultra 5 225T's 59,543, a 71% advantage. Data compression shows a similar pattern: the AMD chip posts 354,510 versus 233,998, a 51.5% lead. Random string sorting also favors AMD by 37.1% (39,447 versus 28,774), and extended instructions go to AMD by 25% (25,113 versus 20,083). The Ryzen AI 9 365 also wins the PassMark multithread test with 29,467 against 25,358, a 16.2% margin, and takes Cinebench R15 multicore at 2,842 versus 2,214, a 28.4% lead. Data encryption is effectively a tie, with AMD ahead by a rounding-level 18297 versus 18289, a delta of 0%.

The Intel Core Ultra 5 225T counters with strong single-core performance. In Cinebench R23 single-core, it scores 3,101 versus 1,992, which is 35.8% higher. Cinebench R15 single-core is closer, with Intel ahead at 312 versus 303, a 2.9% margin. PassMark single-thread shows Intel at 4,348 versus 3,841, an 11.7% lead. Prime number finding is a particularly large Intel win: 284 versus 117, a 58.8% margin. Floating-point math also favors Intel at 82,751 versus 62,802, a 24.1% lead, and the physics test goes to Intel at 2,053 versus 1,704, a 17% advantage. In Cinebench R23 multicore, Intel takes the win at 21,971 versus 18,698, a 14.9% margin, which is notable given the AMD part's superior multithread score elsewhere.

The average benchmark scores reinforce this divergence. The AMD Ryzen AI 9 365 has an average benchmark score of 40,048, while the Intel Core Ultra 5 225T sits at 30,468. However, the Intel part's nearest rival list includes the Intel Core i9-11980HK at 30,422 (0.2% delta), the AMD Ryzen 5 7640HS at 30,390 (0.3% delta), and the AMD Ryzen 7 7736U at 30,364 (0.3% delta), placing it in a lower overall performance tier. The AMD part, by contrast, is near the AMD Ryzen 7 7700 at 40,081 (-0.1% delta) and the Intel Core 5 221E at 40,144 (-0.2% delta), indicating a higher absolute performance class despite its mobile designation.

Architecture Differences

The two processors come from fundamentally different design schools. The AMD Ryzen AI 9 365 uses a Zen 5 architecture on the Strix Point codename, built on a 4 nm process at TSMC with a die size of 233 mm². It has 10 cores and 20 threads, meaning each core supports two threads via simultaneous multithreading. The Intel Core Ultra 5 225T uses the Arrow Lake architecture (Arrow Lake-S codename) on a 3 nm process, also from TSMC, with a die size of 243 mm². It has 10 cores but only 10 threads, so no hyperthreading is present; each core handles a single thread.

Cache layouts differ significantly. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel part has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. This gives Intel a larger per-core cache footprint and a larger last-level cache, which helps explain its single-threaded and floating-point advantages.

Clock speeds also differ. The AMD chip has a 2.00 GHz base clock and a 5.00 GHz boost clock, while the Intel chip runs at a 2.50 GHz base and a 4.90 GHz boost. The Intel base clock is higher, but the AMD boost clock is higher by 0.10 GHz. Thermal design power is a major differentiator: the AMD part is rated at 28 W, the Intel part at 65 W. The Intel chip uses more than double the power budget, which is consistent with its desktop market segment versus AMD's mobile segment.

Memory support and bandwidth differ as well. The AMD Ryzen AI 9 365 supports DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s of bandwidth. The Intel Core Ultra 5 225T supports only DDR5, also dual-channel, but with 102.4 GB/s of bandwidth, a 14.3% higher figure. Neither part supports ECC memory.

PCIe connectivity is another split. The AMD part uses PCIe Gen 4 with 16 lanes (CPU only), while the Intel part uses PCIe Gen 5 with 20 lanes (CPU only), offering both a newer standard and more lanes.

The integrated graphics differ sharply. AMD includes the Radeon 880M, while Intel uses the Arc Xe-LPG Graphics 16EU. The cache and memory architecture suggest the Intel part is designed for desktop throughput with a higher power envelope, while the AMD part is optimized for mobile efficiency with a much lower TDP.

The transistor count is only listed for the Intel part: 17,800 million transistors. The AMD part's transistor count is not recorded. The production status for both is Active.

The release dates are also recorded: AMD on 2024-06-30 and Intel on 2024-12-31, placing the AMD part six months earlier. The AMD part uses AMD Socket FP8, while the Intel part uses Intel Socket 1851.

The AMD part has a generation label of "Ryzen AI 300 (Zen 5 / Zen 5c)", indicating a hybrid core arrangement within the Zen 5 family. The Intel part is labeled "Ultra 5 (Arrow Lake)". Neither part has an unlocked multiplier, so both are locked for overclocking.

The Verdict

The recorded data points to two distinct usage profiles. The AMD Ryzen AI 9 365 is the stronger choice for integer-heavy, compression, and multithreaded general workloads. Its 71% lead in integer math, 51.5% lead in data compression, and 16.2% lead in PassMark multithread make it the clear pick for tasks that stress parallel integer execution. Its 28 W TDP also makes it suitable for mobile platforms, as indicated by its Socket FP8 and mobile market segment. The average benchmark score of 40,048 places it near desktop-class rivals like the AMD Ryzen 7 7700, which is only 0.1% away, and the Intel Core 5 221E at 0.2% away.

The Intel Core Ultra 5 225T is the better option for single-threaded responsiveness and floating-point calculations. Its 35.8% lead in Cinebench R23 single-core, 58.8% lead in prime number finding, and 24.1% lead in floating-point math demonstrate a strong scalar core design. The higher L3 cache, larger per-core L2, and higher memory bandwidth (102.4 GB/s versus 89.6 GB/s) support this pattern. However, its 65 W TDP and desktop socket (Intel Socket 1851) indicate a desktop-only deployment, and its average benchmark score of 30,468 places it in a lower tier, near the Intel Core i9-11980HK and AMD Ryzen 5 7640HS, both within 0.3%.

For a user prioritizing peak single-thread performance and floating-point throughput in a desktop form factor, the Intel part delivers on those specific metrics. For a user prioritizing integer throughput, compression, data encryption, and higher aggregate performance while operating at a much lower power envelope, the AMD part is the stronger fit. The Cinebench R23 multicore result is an outlier in favor of Intel, but the broader multithread data, including PassMark multithread and Cinebench R15 multicore, favors AMD.
