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

Head-to-Head Benchmarks

The PassMark suite records eleven head-to-head comparisons between the AMD Ryzen AI 7 450G and the Intel Core Ultra 5 225T, with the AMD part taking six wins and the Intel part taking five. The margins, however, are not evenly distributed. The AMD Ryzen AI 7 450G dominates in several throughput-heavy workloads, while the Intel Core Ultra 5 225T counterattacks in specific computational patterns.

The largest single victory for the AMD Ryzen AI 7 450G comes in data compression, where it scores 402,831 against Intel's 233,998, a delta of 72.2%. That is a massive lead, suggesting the AMD part's thread count and cache architecture handle compression workloads with far greater efficiency. Integer math follows a similar pattern: AMD scores 99,732 versus Intel's 59,543, a 67.5% advantage. Random string sorting also favors AMD heavily, with a score of 42,663 against 28,774, a 48.3% edge. Extended instructions show AMD ahead by 40.5%, scoring 28,223 versus 20,083. These results indicate that AMD's 8 cores and 16 threads, paired with its per-core L1 and L2 cache configuration, deliver substantially higher throughput in integer-heavy and data-manipulation tasks.

The multithread benchmark, often a proxy for overall parallel performance, also goes to AMD: 30,422 versus 25,358, a 20% margin. Data encryption is closer, with AMD at 18,937 and Intel at 18,289, a modest 3.5% advantage for AMD.

The Intel Core Ultra 5 225T, however, claims the remaining five benchmarks, and some of its wins are equally decisive. The standout is find prime numbers, where Intel scores 284 against AMD's 87, a staggering -69.4% delta (meaning AMD trails by that margin). This is a workload that appears to favor Intel's architecture substantially. Physics simulation also favors Intel: 2,053 versus 1,440, a 29.9% lead. Floating point math goes to Intel at 82,751 versus 63,683, a 23% advantage. These results suggest Intel's 10-core, 10-thread configuration excels in workloads that rely on raw floating-point throughput and algorithmic patterns like prime number generation.

Single-thread performance is nearly a tie, but Intel edges ahead: 4,348 versus 4,309, a 0.9% delta. The same result appears in the duplicate singlethread entry, with identical scores. This near-parity in single-thread performance is notable, as it indicates both chips are competitive in lightly threaded tasks, though Intel holds a slight numerical edge.

The overall picture from the head-to-head data is a split personality. AMD wins the tasks that involve large data sets, compression, and integer math, often by very wide margins. Intel wins the tasks that involve floating-point math, physics, and prime number detection, also by significant margins. The average benchmark score in the database reflects this: AMD's average is 63,331, while Intel's is 30,468. That large gap is driven by AMD's enormous scores in data compression and integer math, which pull its average upward. Intel's average is lower, but its wins in physics and floating-point show it is not merely a weaker chip across the board.

The Verdict

The benchmark data suggests a clear split in workload suitability. The AMD Ryzen AI 7 450G is the stronger choice for tasks involving data compression (72.2% ahead), integer math (67.5% ahead), random string sorting (48.3% ahead), and extended instructions (40.5% ahead). It also leads in multithread performance by 20%, and its 93rd percentile ranking versus Intel's 82nd places it higher in the overall CPU distribution. For users running compression utilities, data processing pipelines, or integer-heavy computational workloads, the AMD part delivers substantially higher throughput.

The Intel Core Ultra 5 225T, despite its lower percentile and lower average benchmark score, wins the workloads that depend on floating-point math (23% ahead), physics simulation (29.9% ahead), and prime number generation (69.4% ahead). Its single-thread score is also marginally higher. For scientific computing, physics simulations, or floating-point-heavy algorithms, the Intel part provides measurable advantages.

The choice between these two processors depends entirely on the dominant workload. The database records six wins for AMD and five for Intel, but the magnitudes differ. AMD's wins are often enormous (72.2%, 67.5%, 48.3%), while Intel's wins range from narrow (0.9%) to very large (69.4%). The data does not support a universal recommendation; it supports a workload-specific one.

Specification Differences

The two processors differ in several fundamental specifications. The AMD Ryzen AI 7 450G has 8 cores and 16 threads, while the Intel Core Ultra 5 225T has 10 cores and 10 threads. AMD's base clock is 2.00 GHz with a boost clock of 5.10 GHz. Intel's base clock is 2.50 GHz with a boost clock of 4.90 GHz. Both are rated at 65 W TDP.

The AMD part uses AMD Socket AM5, while Intel uses Intel Socket 1851. AMD's process node is 4 nm from TSMC, while Intel's is 3 nm, also from TSMC. Intel's die size is 243 mm² versus AMD's 195 mm². Intel lists its transistor count as 17,800 million, while AMD does not record a transistor count.

Cache configurations differ significantly. AMD has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. Intel has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. Memory support differs as well: AMD supports DDR5 and LPDDR5X, while Intel supports only DDR5. Both use dual-channel memory buses, but AMD's memory bandwidth is 89.6 GB/s versus Intel's 102.4 GB/s. AMD supports ECC memory; Intel does not. AMD's PCIe is Gen 4 with 12 lanes (CPU only), while Intel's is Gen 5 with 20 lanes (CPU only). AMD's integrated graphics is the Radeon 860M, while Intel uses Arc Xe-LPG Graphics 16EU. AMD's multiplier is unlocked; Intel's is locked. AMD's release date is recorded as 2026-02-28, while Intel's is 2024-12-31.

Architecture Differences

The architecture behind each processor explains much of the benchmark behavior. The AMD Ryzen AI 7 450G is part of the Ryzen AI 400 generation, built on a mix of Zen 5 and Zen 5c cores, with the codename Gorgon Point. The Intel Core Ultra 5 225T is part of the Core Ultra Series 2, using the Arrow Lake architecture, with the codename Arrow Lake-S.

The process nodes differ: AMD uses 4 nm TSMC, while Intel uses 3 nm TSMC. This gives Intel a smaller process, but the benchmark results do not show a universal advantage from it. AMD's cache layout is per-core for L1 and L2, with a relatively small 8 MB L3. Intel's L1 and L2 are larger per core (192 KB and 3 MB respectively), and its L3 is 20 MB shared. These cache differences likely contribute to the divergent results in compression and integer math versus floating-point and physics workloads.

AMD's memory controller supports both DDR5 and LPDDR5X, while Intel supports only DDR5. AMD's ECC support is a feature Intel lacks. PCIe generation also differs, with Intel offering Gen 5 versus AMD's Gen 4, and Intel offers more lanes (20 versus 12). The integrated graphics differ: AMD uses its Radeon 860M, while Intel uses Arc Xe-LPG Graphics 16EU. AMD's unlocked multiplier indicates overclocking capability, while Intel's locked multiplier does not.

Where Each One Wins

Based on the recorded head-to-head benchmarks, the AMD Ryzen AI 7 450G wins in data compression (402,831 versus 233,998), data encryption (18,937 versus 18,289), extended instructions (28,223 versus 20,083), integer math (99,732 versus 59,543), multithread (30,422 versus 25,358), and random string sorting (42,663 versus 28,774). These are tasks that involve moving, transforming, or processing large amounts of data, often with integer arithmetic. The AMD part's 16 threads, despite having fewer physical cores, clearly handle parallel data tasks with high efficiency.

The Intel Core Ultra 5 225T wins in find prime numbers (284 versus 87), floating-point math (82,751 versus 63,683), physics (2,053 versus 1,440), and single-thread tests (4,348 versus 4,309). These are tasks that involve heavy mathematical computation, particularly floating-point operations and algorithmic loops. Intel's 10 physical cores, even without hyperthreading, appear to execute these workloads more efficiently.

The data implies a workload-based split: choose AMD for data-centric, integer-heavy, and compression tasks; choose Intel for math-centric, floating-point-heavy, and physics tasks. The single-thread difference is negligible in practical terms, so the decision hinges on the broader workload profile. The database records AMD at the 93rd percentile and Intel at the 82nd percentile, which reflects AMD's stronger average benchmark score, but the Intel part's specific wins should not be overlooked by users whose applications fall into its strengths.
