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

Head-to-Head Benchmarks

The head-to-head data reveals a clear split between the AMD Ryzen AI 7 450G and the Intel Core Ultra 5 225H, with the AMD part taking seven of the eleven compared workloads. The largest margin belongs to AMD in integer math, where it scores 99,732 against Intel's 68,520, a lead of 45.6%. That result indicates a substantial advantage in arithmetic-heavy tasks that rely on rapid integer processing. Data compression follows a similar trajectory, with AMD at 402,831 versus Intel at 283,451, translating to a 42.1% gap. Extended instructions also favor AMD at 28,223 versus 21,915, a 28.8% edge, and random string sorting shows AMD ahead at 42,663 against 33,654, a 26.8% difference.

The multithread PassMark score confirms AMD's overall throughput advantage, 30,422 versus 28,119, an 8.2% margin. Single-thread performance is close, with AMD at 4,309 and Intel at 4,258, a slim 1.2% lead for AMD. That near parity in single-core work suggests the architectural differences do not translate into a major per-thread gap, but AMD still wins the head-to-head in that category.

Intel's counterattacks come in four specific workloads. The largest is in find prime numbers, where Intel scores 220 against AMD's 87, a 60.5% blowout. That workload likely stresses a particular execution path where Intel's design is far more efficient. Floating point math also goes to Intel, 86,540 versus 63,683, a 26.4% advantage. Physics simulation favors Intel at 1,877 against 1,440, a 23.3% lead. Data encryption is the closest Intel win, 21,428 versus 18,937, an 11.6% margin. The pattern is striking: Intel wins in workloads that involve heavy floating-point operations or specialized prime-number detection, while AMD dominates in integer-heavy and memory-oriented tasks.

Where Each One Wins

The benchmark split points to distinct use-case strengths. AMD's wins in data compression, integer math, extended instructions, and random string sorting all involve moving and transforming large amounts of data quickly. The data suggests the Ryzen AI 7 450G is well suited for database workloads, file archiving, and any application that processes structured data or performs repeated integer operations. Its multithread lead of 8.2% further positions it as the stronger choice for general parallel processing across many threads.

Intel's wins in floating point math and physics point toward compute-heavy scientific or simulation workloads. The 26.4% floating-point advantage is significant for rendering, engineering simulations, or any code that relies on non-integer calculations. The prime-number result, a 60.5% lead, is more niche but indicates a particular strength in certain algorithmic patterns, potentially number-theoretic computations or cryptographic key generation. The encryption win, while modest at 11.6%, suggests Intel handles cryptographic workloads more efficiently. The physics result, 23.3% ahead, reinforces the simulation angle.

For a desktop user running a mix of everyday applications, AMD's broader set of wins and higher multithread score likely translate into more consistent real-world responsiveness. For a user whose primary workloads are floating-point heavy, Intel's narrower but decisive advantages in those specific tests could matter more.

Architecture Differences

The two processors take fundamentally different design approaches. AMD's Ryzen AI 7 450G uses the Gorgon Point codename with a Ryzen AI 400 generation based on Zen 5 and Zen 5c cores. It packs 8 cores and 16 threads, meaning each core supports two threads. The process node is 4 nm from TSMC, with a die size of 195 mm². The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. The base clock is 2.00 GHz with a boost of 5.10 GHz. The TDP is rated at 65 watts, and the socket is AMD Socket AM5.

Intel's Core Ultra 5 225H belongs to the Core Ultra Series 2, built on the Arrow Lake architecture with the Arrow Lake-H codename. It has 14 cores but only 14 threads, indicating that most or all cores lack simultaneous multithreading. The process node is 3 nm from TSMC, a smaller geometry than AMD's 4 nm. The cache design differs sharply: 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. Base clock is 1.70 GHz with a boost of 4.90 GHz. The TDP is much lower at 28 watts, and the socket is Intel BGA 2049, a mobile package.

The thread count difference is notable: AMD offers 16 threads from 8 cores, while Intel offers 14 threads from 14 cores. That means Intel relies on more physical cores but no hyperthreading, whereas AMD uses fewer physical cores with simultaneous multithreading. The L3 cache difference is substantial, 8 MB for AMD versus 18 MB for Intel, which could explain Intel's floating-point strength if those workloads benefit from larger shared cache. The process node advantage for Intel, 3 nm versus 4 nm, may contribute to its lower TDP of 28 watts versus 65 watts.

Memory support is similar, with both using DDR5 and LPDDR5X in a dual-channel configuration. However, memory bandwidth differs: AMD lists 89.6 GB/s, while Intel lists 102.4 GB/s. PCIe support also diverges, with AMD using Gen 4 at 12 lanes and Intel using Gen 5 at 8 lanes. Intel's support for Gen 5, despite fewer lanes, offers higher per-lane bandwidth. ECC memory is supported on AMD but not on Intel. Integrated graphics differ as well, with AMD featuring Radeon 860M and Intel featuring Arc Graphics 130T.

The Verdict

The recorded data indicates that the AMD Ryzen AI 7 450G is the stronger overall performer in the compared benchmarks, winning 7 of 11 head-to-head tests and posting a higher multithread score by 8.2%. Its percentile rank of 93 versus Intel's 82 places it well above in the broader CPU population. The average benchmark score for AMD is 63,331, while Intel averages 31,508, though that comparison mixes different benchmark suites and should be viewed cautiously.

AMD's wins in integer math, data compression, extended instructions, and random string sorting suggest it handles data-intensive and general-purpose workloads with greater efficiency. The single-thread parity, within 1.2%, means neither chip has a decisive edge in lightly threaded tasks. AMD's higher TDP of 65 watts versus 28 watts indicates it draws more power, but for desktop use that trade-off may be acceptable given the performance gains.

Intel's case rests on specific strengths. The 60.5% lead in prime-number finding and the 26.4% advantage in floating-point math are not trivial. For users running simulation, scientific, or floating-point-heavy applications, the Core Ultra 5 225H could be the better choice despite losing the overall benchmark count. Its larger 18 MB L3 cache and 3 nm process node likely contribute to those wins. The lower TDP also makes it attractive for mobile or power-constrained systems.

The desktop versus mobile split is clear from the sockets and market segments. AMD uses Socket AM5 and is classified as desktop, while Intel uses BGA 2049 and is classified as mobile. A user building a desktop system would naturally gravitate toward AMD, while a laptop or compact mobile design would require Intel. The data does not suggest one is universally superior; it shows a division of labor based on workload type.
