AMD Ryzen AI 7 450G vs Intel Core i9-13900K Comparison

The AMD Ryzen AI 7 450G and Intel Core i9-13900K represent two very different desktop computing philosophies. The Ryzen AI 7 450G is a 2026-era 8-core part built on a 4nm process, while the Core i9-13900K is a 2022 24-core flagship on Intel's 10nm node. In the database's head-to-head passmark suite, the Intel part wins all 11 tests, but the AMD part holds a higher overall average benchmark score and percentile rank. This split tells a story of raw throughput versus efficiency and platform modernity.

Where Each One Wins

The Intel Core i9-13900K wins every single head-to-head benchmark recorded in the database. That includes all passmark tests: data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithread, physics, random string sorting, and single-thread. The margins are often large, ranging from 6.5% in single-thread to 63.1% in prime number finding. For any workload that scales with core count or raw compute, the i9-13900K is the clear winner.

The AMD Ryzen AI 7 450G, however, posts a higher average benchmark score across the entire database: 63331 versus 61766 for the Intel part. It also sits at the 93rd percentile of all CPUs, one point above the i9-13900K's 92nd percentile. This suggests that when considering a broader set of benchmarks beyond the passmark suite, the Ryzen AI 7 450G holds its own, likely due to its newer architecture and integrated Radeon 860M graphics. Additionally, the AMD part operates at a 65W TDP compared to the Intel's 125W, indicating a significant efficiency advantage, though the head-to-head scores do not reflect that.

Architecture Differences

The two processors are built on fundamentally different platforms. 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 is fabricated on TSMC's 4nm process, with a die size of 195 mm². The Intel Core i9-13900K is a Raptor Lake-S part, part of the Core 13th Gen series, built on Intel's 10nm process with a larger 257 mm² die.

Core counts differ dramatically: the AMD part has 8 cores and 16 threads, while the Intel part has 24 cores and 32 threads. Cache hierarchies also diverge. Both have 80 KB of L1 per core, but the AMD part has 1 MB of L2 per core and 8 MB of L3, while the Intel part has 2 MB of L2 per core and 36 MB of shared L3. The Intel part's larger L3 cache is a major advantage for data-heavy workloads.

Memory support differs as well. The AMD part supports DDR5 and LPDDR5X with a dual-channel bus and a listed memory bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, but no bandwidth figure is recorded. PCIe connectivity favors Intel: Gen 5 with 16 lanes versus Gen 4 with 12 lanes on the AMD side. Integrated graphics are also different: AMD's Radeon 860M versus Intel's UHD Graphics 770.

The sockets are incompatible: AMD uses Socket AM5, Intel uses Socket 1700. Release dates are far apart: the AMD part launched on 2026-02-28, while the Intel part launched on 2022-09-26. Both are active production parts, both support ECC memory, and both have unlocked multipliers.

Head-to-Head Benchmarks

The passmark suite reveals a consistent pattern. The Intel Core i9-13900K leads in every test, but the magnitude varies. The smallest gap is in single-thread performance: the Intel part scores 4608 against the AMD's 4309, a 6.5% advantage. This is the only test where the two are close. In multithread, the Intel part scores 58589 versus 30422, a 48.1% lead. Data compression shows Intel at 793645 versus 402831, a 49.2% lead. Integer math: 207792 versus 99732, a 52% lead. Physics: 3140 versus 1440, a 54.1% lead. Floating point math: 151562 versus 63683, a 58% lead. Data encryption: 46609 versus 18937, a 59.4% lead. Prime number finding: 236 versus 87, a 63.1% lead. Extended instructions: 46477 versus 28223, a 39.3% lead. Random string sorting: 87705 versus 42663, a 51.4% lead.

These numbers show that the Intel part is roughly 40% to 60% faster in most compute-heavy workloads, with the single-thread gap being the only exception. The AMD part's higher overall average benchmark score, despite losing all head-to-head passmark tests, suggests that other benchmark categories, possibly those involving the integrated GPU or memory bandwidth, may favor the AMD part.
