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

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core Ultra 5 245KF, which wins 10 of the 11 recorded head-to-head tests. The AMD Ryzen AI 7 450G manages a single win, but the magnitude of the Intel wins in most tests is substantial.

The largest gap appears in the prime number test, where the Intel part scores 416 against 87 for the AMD, a 79.1% advantage. This is an outlier, but it points to a very large difference in the kind of integer work that stresses branch prediction and core throughput. Floating point math also heavily favors Intel, with the 245KF scoring 131546 versus 63683, a 51.6% lead. Physics simulation shows a similar pattern: 2998 versus 1440, a 52% gap. The Intel chip also dominates data encryption, scoring 33381 against 18937, a 43.3% lead. Extended instructions favor Intel by 25.6% (37912 vs 28223), and random string sorting favors Intel by 22.7% (55206 vs 42663).

The multithread score is a key overall indicator. Intel scores 43110, which is 29.4% ahead of the AMD's 30422. That is a wide margin for parallel workloads. Data compression shows a 12.5% lead for Intel, with scores of 460123 and 402831 respectively.

Single-thread performance is closer, but still favors Intel. The 245KF scores 4715 in the PassMark single-thread test, while the 450G scores 4309, an 8.6% gap. The one AMD win is in integer math, where the 450G scores 99732 against 98854, a slim 0.9% margin. That result is essentially a tie, but it is the only recorded test where the AMD part comes out ahead.

The average benchmark score tells a more nuanced story. The AMD Ryzen AI 7 450G has an average score of 63331, which places it in the 93rd percentile of all CPUs. The Intel Core Ultra 5 245KF has an average score of 55093, placing it in the 91st percentile. Despite losing most head-to-head tests, the AMD part has a higher average score because it is compared against a different set of processors. The Intel chip's nearest rivals include the AMD Ryzen 9 9900X3D (0.6% higher), the Intel Core 7 253PQE (1.5% lower), and the Intel Core i9-14900HX (1.6% lower). The AMD chip's nearest rivals are all within 0.8% of its score, including the Intel Core Ultra 7 265HX at 0.2% lower and the AMD Ryzen AI Max PRO 390 at 0.7% higher.

Architecture Differences

The two processors come from different generations and use different design philosophies. The AMD Ryzen AI 7 450G is part of the Ryzen AI 400 generation, codenamed Gorgon Point, and uses a mix of 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 Intel Core Ultra 5 245KF is part of the Core Ultra Series 2, codenamed Arrow Lake-S, and uses the Arrow Lake architecture. It has 14 cores and 14 threads, with a base clock of 4.20 GHz and a boost clock of 5.20 GHz. The Intel chip has more physical cores, but no hyperthreading, so its thread count equals its core count. The AMD chip has fewer cores but double the thread count.

The process nodes also differ. The AMD chip is built on a 4 nm process, while the Intel chip uses a 3 nm process. Both are fabricated by TSMC. The Intel die is larger at 243 mm², compared to 195 mm² for the AMD chip. The Intel chip also lists 17,800 million transistors, while the AMD chip does not report a transistor count.

Cache layouts differ significantly. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger L3 cache on the Intel part is likely a factor in its stronger multithread and compression scores. The AMD chip supports both DDR5 and LPDDR5X memory, while the Intel chip supports DDR5 only. Both use dual-channel memory, but the Intel chip has a higher rated memory bandwidth at 102.4 GB/s versus 89.6 GB/s for the AMD chip. The AMD chip supports ECC memory, while the Intel chip does not.

PCIe support also differs. The AMD chip uses Gen 4 with 12 lanes from the CPU, while the Intel chip uses Gen 5 with 20 lanes from the CPU. The Intel platform offers newer and wider PCIe connectivity. The AMD chip includes integrated graphics in the form of a Radeon 860M, while the Intel chip has no integrated graphics, as indicated by the "N/A" entry. The Intel chip's "KF" designation typically indicates a lack of integrated graphics, and the data confirms that here.

The AMD chip was released later, on 2026-02-28, while the Intel chip was released on 2024-10-23. The Intel chip has a launch MSRP of $294. The AMD chip has no recorded launch MSRP. Both processors have unlocked multipliers, and both are marked as Active in production status. The AMD chip uses the AMD Socket AM5, while the Intel chip uses Intel Socket 1851.

Where Each One Wins

The Intel Core Ultra 5 245KF wins in nearly every measured category. Its strongest advantages are in prime number calculation (79.1% ahead), physics (52% ahead), and floating point math (51.6% ahead). These results indicate a clear edge in raw computational throughput, particularly for workloads that use many cores or heavy arithmetic. The 29.4% lead in multithread performance confirms that the Intel chip is the stronger choice for parallel processing tasks. It also leads in single-thread performance by 8.6%, so it is not merely a multicore specialist.

The AMD Ryzen AI 7 450G wins only in integer math, with a 0.9% margin. This is a narrow result and not enough to shift the overall picture. However, the AMD chip has the advantage of integrated graphics, which the Intel chip lacks entirely. That makes the AMD part suitable for systems that do not use a discrete graphics card. The AMD chip also supports ECC memory, which is a feature for specialized reliability-focused builds. The AMD chip supports LPDDR5X memory in addition to DDR5, which may matter for certain low-power or compact designs.

The Intel chip is the clear winner for performance-focused builds where a discrete GPU is already planned. The AMD chip is the more flexible option for systems that need graphics output without an add-in card.

The Verdict

The benchmark data indicates that the Intel Core Ultra 5 245KF is the stronger processor for raw performance. It wins 10 of 11 head-to-head tests, with particularly large leads in prime number calculation, physics, floating point math, and multithread performance. Its higher core count, larger L3 cache, higher memory bandwidth, and newer PCIe Gen 5 support all align with those results. The 29.4% multithread lead and the 8.6% single-thread lead make it the appropriate choice for compute-heavy desktop workloads.

The AMD Ryzen AI 7 450G is the better fit for systems that require integrated graphics, ECC memory support, or LPDDR5X memory compatibility. Its single head-to-head win in integer math is narrow, but its higher average benchmark score and 93rd percentile ranking show that it competes well against its own nearest rivals. The lower TDP of 65 W versus 125 W also indicates a more power-efficient design, though the data does not include specific power measurements.

The choice depends on the system configuration. For a desktop with a discrete GPU and a focus on maximum throughput, the data favors the Intel Core Ultra 5 245KF. For a platform that needs graphics output, ECC support, or lower power draw, the AMD Ryzen AI 7 450G is the appropriate pick based on the recorded specifications and benchmark results.
