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

Head-to-Head Benchmarks

The benchmark data splits these two desktop processors into distinct roles. The AMD Ryzen AI 7 450G wins 4 of the 11 head-to-head comparisons, while the Intel Core Ultra 5 235T takes 7, but the margins tell a more important story than the raw win count. The AMD part dominates in memory and integer-heavy workloads, while the Intel part excels in floating-point, prime-number, and physics calculations.

The largest single victory belongs to AMD in data compression. The Ryzen AI 7 450G scores 402831 against Intel's 295100, a 36.5% lead. This is the clearest performance gap in the entire comparison, and it aligns with the AMD processor's higher integer math output. AMD also wins extended instructions by 21.6% (28223 versus 23212), random string sorting by 20.6% (42663 versus 35377), and integer math by 18.4% (99732 versus 84244). These four wins are all in the 18% to 37% range, showing a consistent pattern of AMD strength in data manipulation and general-purpose compute.

Intel's wins are more numerous but varied in magnitude. The biggest is find prime numbers, where Intel scores 318 against AMD's 87, a massive 72.6% advantage. Floating-point math goes to Intel by 40.2% (106546 versus 63683), and physics by 33.2% (2157 versus 1440). Data encryption shows Intel ahead by 19.3% (23457 versus 18937). The remaining Intel victories are narrow: multithread by 1.6% (30918 versus 30422) and single-thread by 0.7% (4339 versus 4309). The single-thread margin is effectively a tie in practical terms, while the multithread gap is small enough that the AMD part's 8 cores and 16 threads nearly match Intel's 14 cores and 14 threads in overall throughput.

Looking at the overall averages, the AMD Ryzen AI 7 450G posts an average benchmark score of 63331, placing it in the 93rd percentile of all CPUs in the database. The Intel Core Ultra 5 235T averages 38561, sitting in the 86th percentile. The two chips occupy different segments of the performance distribution: AMD's nearest rivals include the Intel Core Ultra 7 265HX at 63173 (0.2% behind), the Intel Core i7-13790F at 63080 (0.4% behind), the AMD Ryzen AI Max PRO 390 at 63765 (0.7% ahead), and the AMD Ryzen AI Embedded P185 at 62839 (0.8% behind). Intel's nearest rivals are the Intel Core i5-14500 at 38531 (0.1% behind), the Intel Xeon w3-2525 at 38392 (0.4% behind), the Intel Core 9 270H at 38335 (0.6% behind), and the Intel Core Ultra 9 285H at 38312 (0.7% behind). These rival clusters confirm that the two processors are not direct competitors in the same performance tier; the AMD part competes with higher-end silicon, while the Intel part sits among mid-range desktop and mobile parts.

Architecture Differences

The two processors come from different design philosophies and manufacturing processes. The AMD Ryzen AI 7 450G uses the Gorgon Point codename from the Ryzen AI 400 generation, built on a hybrid Zen 5 / Zen 5c core arrangement. It is fabricated on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core Ultra 5 235T uses the Arrow Lake architecture, specifically Arrow Lake-S, from the Ultra 5 generation. It is built on a 3 nm process, also at TSMC, with a larger die size of 243 mm² and 17,800 million transistors. The Intel part has a newer, denser process node but a physically larger die.

Core counts differ substantially. The AMD chip has 8 cores and 16 threads, relying on simultaneous multithreading to double its thread count. The Intel chip has 14 cores and 14 threads, with no hyperthreading, meaning each core corresponds to exactly one thread. Despite having 6 more cores, Intel only manages 2 fewer threads than AMD. The cache hierarchy reflects this split: AMD provides 80 KB of L1 per core and 1 MB of L2 per core, with a total of 8 MB of L3. Intel provides 192 KB of L1 per core and 3 MB of L2 per core, with a shared 24 MB of L3. Intel's larger L3 cache is three times AMD's total, which helps explain its strong performance in floating-point and physics workloads.

Memory support also diverges. AMD supports both DDR5 and LPDDR5X across a dual-channel bus with 89.6 GB/s of bandwidth and ECC memory support. Intel supports only DDR5 on a dual-channel bus but with higher bandwidth at 102.4 GB/s and no ECC support. PCIe connectivity differs as well: AMD offers Gen 4 with 12 CPU lanes, while Intel offers Gen 5 with 20 CPU lanes. The integrated graphics are different products: AMD uses the Radeon 860M, while Intel uses Arc Xe-LPG Graphics 24EU. Both processors are desktop parts with a 65 W TDP and are currently Active in production. The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD part launches on an AM5 socket with a February 2026 release date, while the Intel part uses Socket 1851 with a January 2025 release date.

Where Each One Wins

The AMD Ryzen AI 7 450G wins in data compression, extended instructions, integer math, and random string sorting. These are workloads that depend on memory access patterns, integer throughput, and instruction-level efficiency. The 36.5% lead in data compression and the 18.4% lead in integer math indicate that the Ryzen AI 7 450G is the stronger choice for database operations, file compression tasks, and general application responsiveness where integer operations dominate. The extended instructions win by 21.6% also suggests strong support for SIMD and specialized instruction sets.

The Intel Core Ultra 5 235T wins in find prime numbers, floating-point math, physics, data encryption, multithread, and single-thread. The 72.6% margin in prime number finding and the 40.2% margin in floating-point math point to a processor that handles repetitive floating-point loops and scientific calculations more efficiently. The 33.2% physics advantage further confirms Intel's strength in simulation and game physics workloads. The data encryption win by 19.3% matters for security-related tasks and cryptography. The narrow multithread win (1.6%) and single-thread win (0.7%) mean Intel also edges out AMD in general mixed-thread productivity, though by a small margin.

The overall average benchmark score difference is substantial: 63331 for AMD versus 38561 for Intel. However, this average includes the AMD part's much higher compression score, which skews the aggregate. The head-to-head results show a more balanced picture: AMD wins 4 tests with an average margin of 24.3%, while Intel wins 7 tests with an average margin of 24.0%. The two chips effectively split the workload categories, with AMD taking data-oriented tasks and Intel taking compute-oriented tasks.

The Verdict
