AMD Ryzen AI 7 450G vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between the AMD Ryzen AI 7 450G and the Intel Core Ultra 5 245T. Intel wins the majority of the head-to-head tests, taking 7 of 11 comparisons, while AMD secures 4 wins. However, the magnitude of those wins tells a more nuanced story than the raw count suggests.

AMD's most dominant victory comes in data compression, where the Ryzen AI 7 450G scores 402831 against Intel's 283812, a 41.9% advantage. This is the largest delta in either direction across the entire benchmark suite. The extended instructions test also favors AMD substantially, with the 450G posting 28223 versus 22071, a 27.9% lead. Random string sorting goes to AMD as well, 42663 against 34931, a 22.1% margin. The integer math test completes AMD's winning set, with 99732 compared to Intel's 88676, a 12.5% edge.

Intel's wins are concentrated in different workload types. The floating point math test shows a massive Intel advantage: 108499 versus 63683, a 41.3% lead. Prime number finding is even more lopsided in percentage terms, with Intel scoring 324 against AMD's 87, a 73.1% difference. Physics simulation also favors Intel decisively, 2278 versus 1440, a 36.8% gap. Data encryption goes to Intel at 23656 against 18937, a 19.9% margin.

The closest contests are the multithread and single-thread tests. In multithread, Intel edges ahead with 30833 versus 30422, just a 1.3% difference. Single-thread performance is similarly tight, with Intel at 4367 and AMD at 4309, also a 1.3% gap. These near-ties indicate that general-purpose throughput is essentially comparable between the two processors, despite their very different core configurations.

The average benchmark scores reveal a broader performance picture. The AMD Ryzen AI 7 450G achieves an average benchmark score of 63331, placing it in the 93rd percentile among all CPUs. The Intel Core Ultra 5 245T averages 38194, sitting in the 86th percentile. This substantial gap in average scores, about 65% higher for AMD, stems from the fact that AMD's benchmark portfolio in the database includes more high-scoring tests relative to the included Cinebench results for Intel.

Looking at nearest rivals provides additional context. The AMD processor's closest competitor is the Intel Core Ultra 7 265HX with an average score of 63173, a mere 0.2% difference. The AMD Ryzen AI Max PRO 390 sits 0.7% higher at 63765. For Intel, the nearest rival is the AMD Ryzen 7 250 at 38221, just 0.1% below, while the Intel Core i5-13600KF trails by 0.2% at 38103. These tight groupings suggest both processors are well-positioned within their respective performance tiers.

Architecture Differences

The two processors diverge fundamentally in their design approaches. The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation built on a hybrid of Zen 5 and Zen 5c cores. It packs 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Core Ultra 5 245T, part of the Core Ultra Series 2, uses Arrow Lake architecture with 14 cores and 14 threads. Its base clock is 2.20 GHz, and it also boosts to 5.10 GHz.

The core count difference is notable: Intel provides 14 physical cores but no hyperthreading, yielding 14 threads. AMD offers fewer cores at 8 but doubles them via simultaneous multithreading to reach 16 threads. This explains why multithread performance ends up nearly identical despite the core disparity.

Manufacturing processes differ as well. AMD fabricates on a 4 nm node at TSMC, while Intel also uses TSMC but at 3 nm. The die sizes reflect this: AMD's die measures 195 mm², while Intel's is larger at 243 mm². Intel's transistor count is listed at 17,800 million, whereas AMD's transistor count is not recorded in the database.

Cache hierarchies show significant divergence. AMD allocates 80 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3. Intel provides 192 KB of L1 per core and 3 MB of L2 per core, with a substantially larger 24 MB of shared L3. The L3 difference, 8 MB versus 24 MB, could influence workloads that benefit from larger shared pools of fast memory.

Memory support also differs. AMD supports both DDR5 and LPDDR5X, while Intel lists only DDR5. Both use dual-channel memory buses, but Intel's memory bandwidth is higher at 102.4 GB/s versus AMD's 89.6 GB/s. Both processors support ECC memory.

PCIe connectivity presents another contrast. AMD provides Gen 4 with 12 lanes from the CPU, while Intel offers Gen 5 with 20 lanes. This gives Intel a substantial advantage in available expansion bandwidth for GPUs, NVMe storage, or other peripherals.

Integrated graphics take different forms: AMD includes the Radeon 860M, while Intel features Arc Xe-LPG Graphics with 64 execution units. Both target desktop sockets, AMD Socket AM5 for the Ryzen and Intel Socket 1851 for the Core Ultra.

The Verdict

The data indicates two processors with complementary strengths rather than a single superior choice. The AMD Ryzen AI 7 450G dominates in data compression, extended instructions, random string sorting, and integer math. These are workloads that often appear in productivity, database, and general application scenarios. Its 41.9% lead in data compression is the standout result, suggesting substantial advantage in file handling and archival tasks.

The Intel Core Ultra 5 245T wins in floating point math, prime number finding, physics simulation, data encryption, and narrowly in multithread and single-thread tests. The floating point and physics wins point toward computational simulation and scientific workloads. The 73.1% margin in prime number finding, while a niche test, indicates strong algorithmic efficiency in certain mathematical operations.

The average benchmark scores favor AMD decisively: 63331 versus 38194. The 93rd percentile placement for AMD versus 86th for Intel confirms that the Ryzen AI 7 450G sits higher in the overall performance distribution. However, the head-to-head results show Intel winning more individual tests, suggesting that the average score may reflect the specific mix of tests in AMD's benchmark portfolio.

The architecture differences reinforce the performance split. AMD's smaller die at 195 mm² and 4 nm process contrast with Intel's 243 mm² and 3 nm node. Intel's larger L3 cache and higher memory bandwidth could benefit certain memory-intensive workloads. AMD's support for LPDDR5X and its unlocked multiplier offer flexibility that Intel's locked multiplier does not.

Where Each One Wins

The AMD Ryzen AI 7 450G excels in data manipulation and integer-heavy workloads. Its 41.9% lead in data compression makes it the stronger choice for file archiving, backup utilities, and any application that frequently compresses or decompresses data. The 27.9% advantage in extended instructions suggests better support for specialized CPU instruction sets, potentially benefiting emulation or compatibility layers. Integer math at 12.5% ahead indicates strength in general arithmetic operations common in business applications and spreadsheets. Random string sorting at 22.1% ahead points to advantages in database indexing and text processing tasks.

The Intel Core Ultra 5 245T claims the floating point and physics categories. A 41.3% lead in floating point math makes it preferable for scientific computing, engineering simulations, and 3D rendering that rely heavily on floating point operations. The 36.8% physics advantage reinforces this pattern, suggesting better performance in physics engines used by CAD software or game simulation. The 73.1% margin in prime number finding, while niche, indicates excellent performance in cryptographic and number-theoretic algorithms. Data encryption at 19.9% ahead gives Intel the edge in security-related workloads such as VPN traffic processing or disk encryption. The marginal 1.3% wins in multithread and single-thread tests mean Intel holds a slight overall responsiveness advantage in general desktop use.

The average benchmark scores suggest that AMD's overall performance profile is higher, but Intel's wins in specific test categories are substantial. For workloads that mix compression, integer math, and extended instructions, the AMD Ryzen AI 7 450G delivers clear advantages. For floating point, physics, and encryption workloads, the Intel Core Ultra 5 245T is the data-backed choice. The near-identical multithread and single-thread scores indicate that for mixed general-purpose usage, either processor would perform at a similar level, with the deciding factor being the specific application mix.
