AMD Ryzen AI 7 450G vs Intel Core Ultra 5 235 Comparison

AMD Ryzen AI 7 450G and Intel Core Ultra 5 235 represent two distinct approaches to desktop processing, with the AMD part leveraging a hybrid Zen 5/Zen 5c design on a 4 nm node and the Intel part using a monolithic Arrow Lake architecture on a 3 nm node. The recorded data shows a clear split in workload preferences: the AMD chip wins in integer-heavy and compression tasks, while the Intel chip dominates in floating-point, encryption, and multithreaded throughput. This analysis breaks down where each processor excels, the architectural choices behind those results, and what the benchmark scores indicate for real-world use.

Where Each One Wins

The AMD Ryzen AI 7 450G takes two head-to-head wins in the Passmark suite. Its strongest result is in integer math, where it scores 99,732 against the Intel part's 87,948, a 13.4% advantage. It also leads in data compression with 402,831 versus 390,711, a 3.1% margin. These wins point to workloads that rely on branch-heavy integer logic and tight data packing, where the Zen 5 cores' per-core L1 and L2 cache configuration appears to help.

The Intel Core Ultra 5 235 wins the remaining nine head-to-head comparisons. Its most decisive victory is in prime number finding, where it scores 371 versus the AMD part's 87, a 76.5% gap. Floating-point math also swings heavily Intel's way: 117,951 versus 63,683, a 46% difference. Data encryption goes to Intel at 29,293 versus 18,937, a 35.4% margin, and physics simulation shows Intel ahead at 2,570 versus 1,440, a 44% lead. The multithread score favors Intel at 37,816 versus 30,422, a 19.6% advantage, and single-thread performance is modestly Intel-led at 4,516 versus 4,309, a 4.6% gap. Extended instructions and random string sorting also go to Intel, with margins of 13.8% and 12.9% respectively.

The pattern is consistent: AMD holds the integer and compression niche, while Intel takes everything involving heavy math, cryptography, or parallel compute. For a user deciding between the two, the choice depends entirely on whether the workload leans toward integer processing or floating-point and multithreaded execution.

Architecture Differences

The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. It has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The process node is 4 nm, fabricated by TSMC, and the die size is 195 mm². Cache is split as 80 KB L1 per core, 1 MB L2 per core, and 8 MB L3 total. It supports DDR5 and LPDDR5X memory in dual-channel configuration, with a memory bandwidth of 89.6 GB/s. ECC memory is supported, and the integrated graphics is Radeon 860M. The socket is AMD Socket AM5, and the multiplier is unlocked.

The Intel Core Ultra 5 235 is part of the Core Ultra Series 2, using the Arrow Lake architecture with the Arrow Lake-S codename. It has 14 cores and 14 threads, meaning no hyperthreading, with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. The process node is 3 nm, also TSMC, with 17,800 million transistors on a 243 mm² die. Cache is larger: 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. Memory support is DDR5 only, dual-channel, with a higher bandwidth of 102.4 GB/s. ECC is not supported, and the integrated graphics is Arc Xe-LPG Graphics 24EU. It uses Intel Socket 1851, and the multiplier is locked.

The most significant architectural difference is the core count and threading model. Intel's 14 cores with 14 threads rely on more physical cores for multithreaded work, while AMD's 8 cores with 16 threads use simultaneous multithreading to double the thread count. The Intel part also has substantially more L3 cache, 24 MB versus 8 MB, which contributes to its advantage in cache-sensitive workloads like encryption and physics. The process node difference, 3 nm versus 4 nm, gives Intel a density and efficiency edge, though the AMD part's smaller die size suggests a leaner design. PCIe support also differs: Intel offers Gen 5 with 20 lanes, while AMD offers Gen 4 with 12 lanes.

Head-to-Head Benchmarks

The benchmark data provides a detailed picture of the performance split. In integer math, the AMD Ryzen AI 7 450G scores 99,732 against the Intel Core Ultra 5 235's 87,948, a 13.4% win. This is the largest AMD advantage in any test. Data compression follows a similar trend, with AMD at 402,831 and Intel at 390,711, a 3.1% margin. These two results suggest the AMD architecture handles integer workloads with less overhead, likely due to its Zen 5 core design and efficient thread scheduling.

Intel's wins are more numerous and often larger in magnitude. The prime number test is the extreme case: Intel scores 371 versus AMD's 87, a 76.5% gap. This test is highly sensitive to branch prediction and integer division, areas where the Intel core design shows a clear advantage. Floating-point math is another major Intel win, 117,951 versus 63,683, a 46% difference, indicating the Arrow Lake cores execute FP operations at a much higher rate. Physics simulation, which relies on floating-point vector math, follows with Intel at 2,570 versus 1,440, a 44% lead. Data encryption shows Intel at 29,293 versus 18,937, a 35.4% margin, likely benefiting from the larger L3 cache and AES-NI throughput. Multithread performance favors Intel at 37,816 versus 30,422, a 19.6% advantage, despite AMD having more threads (16 versus 14). Extended instructions go to Intel at 32,752 versus 28,223, a 13.8% gap, and random string sorting to Intel at 48,980 versus 42,663, a 12.9% margin. Single-thread performance is close but Intel-led: 4,516 versus 4,309, a 4.6% difference.

The average benchmark scores in the database place each processor in a different tier. The AMD Ryzen AI 7 450G has an average score of 63,331, with a percentile of 93 among all CPUs. Its nearest rivals are the Intel Core Ultra 7 265HX at 63,173 (0.2% behind), the Intel Core i7-13790F at 63,080 (0.4% behind), the AMD Ryzen AI Max PRO 390 at 63,765 (0.7% ahead), and the AMD Ryzen AI Embedded P185 at 62,839 (0.8% behind). The Intel Core Ultra 5 235 has an average score of 46,062, with a percentile of 89. Its nearest rivals include the AMD Ryzen AI 9 HX 375 at 46,030 (0.1% ahead), the Intel Core i9-13900HX at 46,098 (0.1% behind), the AMD EPYC 4364P at 45,970 (0.2% behind), and the AMD EPYC 7303 at 45,960 (0.2% behind). This places the AMD part in a higher performance class overall, despite losing most head-to-head tests to the Intel part, because its average score is inflated by the integer and compression wins plus a different benchmark mix.

The Verdict

The data indicates that the Intel Core Ultra 5 235 is the stronger choice for users whose workloads involve floating-point math, encryption, physics simulation, or any heavily parallel compute task. Its wins in prime number finding, floating-point math, and multithread performance are decisive, with margins ranging from 19.6% to 76.5%. The larger L3 cache and higher memory bandwidth support these results, and the 14 physical cores provide raw throughput that the AMD part's 16 threads cannot match in these tests.

The AMD Ryzen AI 7 450G is the better option for integer-focused workloads, particularly data compression and integer math, where it leads by 3.1% and 13.4% respectively. Its unlocked multiplier is an advantage for overclocking, and ECC memory support makes it suitable for systems requiring data integrity. The higher average benchmark score of 63,331 and 93rd percentile placement suggest the AMD part sits in a higher overall performance class, but that average is driven by a different benchmark mix rather than head-to-head superiority.

For a builder prioritizing raw compute in math-heavy or multithreaded applications, the Intel Core Ultra 5 235 delivers the better recorded performance. For a user focused on integer workloads, compression, or overclocking flexibility, the AMD Ryzen AI 7 450G is the data-backed choice. The benchmark results do not show a single universal winner; they show two processors optimized for different task profiles, and the correct pick depends on the specific application set.
