AMD Ryzen AI 7 450 vs Intel Core Ultra 5 225T Comparison

AMD Ryzen AI 7 450 and Intel Core Ultra 5 225T occupy different corners of the processor market, and the benchmark data reflects that split clearly. The AMD mobile chip uses a hybrid core layout to push threaded throughput, while the Intel desktop part leans on higher single-core clocks and a larger cache pool. Across the 15 recorded head-to-head tests, Intel takes 9 wins and AMD takes 6, but the margins tell a more nuanced story than the raw tally suggests.

Where Each One Wins

The AMD Ryzen AI 7 450 dominates in integer-heavy and data-oriented workloads. Its PassMark integer math score of 88531 eclipses the Intel part’s 59543, a 48.7% advantage that shows up in compilation, scripting, and general office-style multitasking. The AMD chip also wins PassMark data compression (315906 vs 233998, a 35% lead) and random string sorting (35648 vs 28774, 23.9% ahead), which points to strong memory subsystem performance for its dual-channel LPDDR5X setup. Extended instruction throughput also favors AMD: 22400 vs 20083, an 11.5% edge.

The Intel Core Ultra 5 225T owns the single-threaded and floating-point domain. Its Cinebench R23 single-core score of 3101 beats AMD’s 2038 by 34.3%, and the R15 single-core result shows a similar 31.1% gap (312 vs 215). Floating-point math heavily favors Intel: 82751 vs 54447, a 34.2% lead that matters for scientific computing, physics simulations, and any workload that relies on vector math. The Intel chip also wins prime number finding by a massive 68.7% (284 vs 89), which reflects its superior per-core efficiency in latency-sensitive loops. PassMark single-thread (4348 vs 3901, 10.3% faster) confirms Intel’s advantage in lightly threaded tasks.

The split is straightforward: AMD for parallel integer workloads and data shuffling, Intel for single-core responsiveness and floating-point number crunching.

Architecture Differences

The two processors use fundamentally different design philosophies. AMD’s Ryzen AI 7 450 is built on Zen 5 architecture, codenamed Gorgon Point, using an 8-core, 16-thread configuration. It combines Zen 5 performance cores with Zen 5c efficiency cores, which allows the scheduler to balance power and throughput. The chip is fabricated on TSMC’s 4 nm process with a die size of 195 mm². Cache is distributed per core: 80 KB of L1 and 1 MB of L2 per core, plus 8 MB of shared L3. This is a mobile part on AMD Socket FP8, with a 28 W TDP.

Intel’s Core Ultra 5 225T uses Arrow Lake architecture, specifically Arrow Lake-S, and is a desktop chip on Socket 1851. It has 10 cores and 10 threads, meaning no Hyper-Threading support. The process node is TSMC’s 3 nm, slightly smaller than AMD’s, with a much larger die at 243 mm² and 17,800 million transistors. Cache allocation is very different: 192 KB of L1 per core, 3 MB of L2 per core, and a large 20 MB shared L3 cache. That larger L3 is a key reason Intel wins several latency-sensitive benchmarks. The TDP is 65 W, over double AMD’s, which reflects the desktop power budget.

Other differences: AMD supports both DDR5 and LPDDR5X memory with a measured bandwidth of 89.6 GB/s and ECC enabled. Intel supports only DDR5, but with a higher memory bandwidth of 102.4 GB/s and no ECC. PCIe connectivity also differs: AMD offers Gen 4 with 16 CPU lanes, while Intel provides Gen 5 with 20 CPU lanes. Integrated graphics are Radeon 860M on AMD versus Arc Xe-LPG Graphics 16EU on Intel. AMD’s release date is January 2026; Intel’s is December 2024.

Head-to-Head Benchmarks

The largest AMD win is PassMark integer math, where the Ryzen AI 7 450 scores 88531 against Intel’s 59543, a 48.7% margin. This is a workload where AMD’s 16 threads provide a substantial advantage over Intel’s 10 threads. Data compression follows closely: AMD scores 315906 vs 233998, a 35% lead that indicates better memory bandwidth utilization for the AMD platform in real-world compression tasks.

AMD also wins random string sorting (35648 vs 28774, 23.9% ahead) and extended instructions (22400 vs 20083, 11.5% ahead). The multithreaded PassMark test is close but still favors AMD: 26350 vs 25358, a 3.9% edge. Cinebench R15 multicore shows AMD ahead by 22.5% (2713 vs 2214), though this is an older test that favors AMD’s core count.

Intel’s largest win is find prime numbers, where the Core Ultra 5 225T scores 284 versus AMD’s 89, a 68.7% advantage. This is a pure single-thread integer test with tight loops, and Intel’s higher boost clock of 4.90 GHz versus 5.10 GHz does not help AMD here; the per-core cache and architecture efficiency matter more. Cinebench R23 single-core shows Intel ahead by 34.3% (3101 vs 2038), and the R15 single-core test shows a 31.1% lead (312 vs 215).

Floating-point math is another Intel stronghold: 82751 vs 54447, a 34.2% gap. Physics simulation also favors Intel: 2053 vs 1578, a 23.1% difference. Data encryption goes to Intel with 18289 vs 16247, an 11.2% lead, likely due to AES-NI implementation differences. PassMark single-thread confirms Intel’s single-core superiority: 4348 vs 3901, 10.3% faster.

Notably, Cinebench R23 multicore goes to Intel despite AMD’s extra threads: 21971 vs 18316, a 16.6% lead. This shows that Intel’s larger L3 cache and higher per-core performance can overcome AMD’s thread advantage in a well-scaled rendering workload.

Specification Differences

The two chips diverge on nearly every key specification. Core counts differ: AMD has 8 cores with 16 threads, Intel has 10 cores with 10 threads. Base clocks are 2.00 GHz for AMD and 2.50 GHz for Intel, while boost clocks are 5.10 GHz for AMD and 4.90 GHz for Intel. The TDP is 28 W for AMD versus 65 W for Intel. The socket is AMD FP8 versus Intel 1851. Process nodes are 4 nm versus 3 nm, with die sizes of 195 mm² versus 243 mm².

Cache structures are radically different: AMD uses 80 KB L1 and 1 MB L2 per core with 8 MB shared L3; Intel uses 192 KB L1 and 3 MB L2 per core with 20 MB shared L3. Memory support shows AMD accepts both DDR5 and LPDDR5X, while Intel only supports DDR5. Memory bandwidth is 89.6 GB/s for AMD and 102.4 GB/s for Intel. ECC is supported only on AMD. PCIe generation and lane counts differ: Gen 4 with 16 lanes for AMD, Gen 5 with 20 lanes for Intel. Integrated graphics are Radeon 860M for AMD versus Arc Xe-LPG Graphics 16EU for Intel. The production status for both is Active.

The Verdict

The data points to a clear use-case split. The AMD Ryzen AI 7 450 is the stronger choice for integer-heavy parallel workloads, data compression, and string manipulation. Its 16 threads and 28 W TDP make it suitable for thin-and-light mobile systems where battery life and multithreaded productivity matter. The benchmark results show it leads by 48.7% in integer math and 35% in data compression, which covers typical office tasks, code compilation, and file handling.

The Intel Core Ultra 5 225T is the pick for single-thread responsiveness and floating-point computation. Its 34.3% lead in Cinebench R23 single-core and 34.2% lead in floating-point math make it better for rendering engines that rely on a few fast cores, physics simulations, and any application that does not scale well across threads. The 20 MB L3 cache and 65 W TDP indicate a desktop-oriented part that prioritizes peak performance over efficiency.

For a mobile user who runs many concurrent applications, the AMD chip’s thread advantage and lower power draw are compelling. For a desktop user who wants fast single-core response and strong FP32/FP64 throughput, the Intel chip delivers. The overall win count favors Intel (9 vs 6), but the magnitude of AMD’s integer wins is substantial. The average benchmark score favors AMD (39485 vs 30468), but that figure is skewed by AMD’s massive data compression score. Choose based on workload, not averages.
