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

Where Each One Wins

The benchmark data splits this matchup into two very different profiles. The Intel Core i9-13900T wins 9 of 11 recorded head-to-head tests, while the AMD Ryzen AI 7 450G wins only 2. Those two AMD victories are confined to single-threaded workloads, where the Ryzen posts a score of 4309 against Intel's 4177, a 3.2% advantage. For users whose primary metric is raw single-core responsiveness, the AMD part holds a measurable, if modest, edge.

Everything else falls to Intel. The most lopsided result is in data encryption, where the i9-13900T scores 34415 versus 18937 for the Ryzen, a 45% gap. Prime number finding is similarly one-sided: Intel scores 175 to AMD's 87, a 50.3% deficit for the Ryzen. Physics simulation shows Intel ahead by 42.3%, floating point math by 41.5%, integer math by 36.6%, random string sorting by 32.7%, multithread by 29.3%, and data compression by 25.2%. The narrowest Intel win is in extended instructions, where the margin is only 5%.

The multithread result is particularly telling. Intel's 43036 score versus AMD's 30422 reflects a 24-core, 32-thread design overwhelming an 8-core, 16-thread one in parallel throughput. The Ryzen's 93rd percentile ranking among all CPUs and Intel's 92nd percentile show both are high-performing parts, but the percentile parity masks a very different distribution of strengths. The average benchmark score tells a similar story: AMD's 63331 average sits slightly above Intel's 61723, but that average is dragged down by Intel's narrower single-threaded showing while its multithreaded wins dominate the individual tests.

In short, the AMD Ryzen AI 7 450G is the choice for lightly threaded, latency-sensitive workloads where a single core's efficiency matters most. The Intel Core i9-13900T is the choice for heavily threaded, throughput-oriented workloads, especially those involving encryption, compression, or large mathematical workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation built on the Zen 5 / Zen 5c architecture. It is manufactured on a 4 nm process at TSMC. The Intel Core i9-13900T uses the Raptor Lake architecture, specifically Raptor Lake-S, and is built on a 10 nm process at Intel's own fabs. The process node difference is significant: AMD's 4 nm process is denser, but Intel compensates with a much larger die.

Core counts diverge sharply. The Ryzen offers 8 cores and 16 threads, while the i9-13900T offers 24 cores and 32 threads. That threefold core advantage explains most of the multithreaded benchmark gap. Cache hierarchies also differ. Both parts have 80 KB of L1 per core, but the Intel part has 2 MB of L2 per core versus 1 MB for AMD, and Intel's L3 is 36 MB shared versus AMD's 8 MB. The L3 difference is enormous: Intel has 4.5 times the last-level cache, which helps in workloads with large working sets.

Memory support shows a split. The AMD part supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both use dual-channel memory buses. AMD lists a memory bandwidth figure of 89.6 GB/s; Intel's memory bandwidth is not recorded in the database. Both parts support ECC memory.

PCIe connectivity favors Intel. The i9-13900T provides Gen 5 with 20 lanes from the CPU, while the Ryzen provides Gen 4 with 12 lanes. The integrated graphics differ as well: AMD pairs the CPU with a Radeon 860M, Intel with UHD Graphics 770.

The socket and platform divide the two. AMD uses Socket AM5, Intel uses Socket 1700. The AMD multiplier is unlocked, whereas Intel's is locked. The Intel part has a 35 W TDP, while the AMD part has a 65 W TDP, despite AMD having fewer cores. The Intel release date is recorded as 2023-01-03, while AMD's is 2026-02-28. The Intel part has a launch MSRP of $549; the AMD part has no listed launch MSRP.

Head-to-Head Benchmarks

The head-to-head results present a consistent pattern of Intel dominance in compute-heavy tasks, with a single AMD bright spot. Starting with the biggest margin, the passmark_find_prime_numbers test shows Intel at 175 versus AMD at 87, a 50.3% gap. This is the largest relative difference in the entire set. Data encryption follows closely: Intel scores 34415, AMD scores 18937, a 45% deficit for AMD. Physics simulation shows Intel at 2497 versus 1440, a 42.3% gap. Floating point math results in Intel at 108779 and AMD at 63683, a 41.5% difference. Integer math shows Intel at 157324 versus 99732, a 36.6% gap.

The multithread test, often considered a good overall throughput indicator, gives Intel 43036 against AMD's 30422, a 29.3% advantage. Random string sorting shows Intel at 63358 versus 42663, a 32.7% gap. Data compression gives Intel 538254 versus 402831, a 25.2% gap. The narrowest Intel win is in extended instructions, with Intel at 29719 and AMD at 28223, a 5% difference.

The AMD wins are both in single-threaded tests, and both are identical in magnitude. The passmark_single_thread and passmark_singlethread results both show AMD at 4309 and Intel at 4177, a 3.2% margin for AMD. This is the only category where the Ryzen's architectural efficiency overcomes Intel's raw core count.

The benchmark data supports a clear conclusion: the Intel Core i9-13900T is decisively stronger in parallel and math-heavy workloads, while the AMD Ryzen AI 7 450G holds a narrow but real advantage in single-threaded performance. The average benchmark scores, 63331 for AMD and 61723 for Intel, reflect these mixed results, with AMD's higher average driven by its single-threaded strength and Intel's lower average pulled down by the same factor. The percentile rankings, 93rd for AMD and 92nd for Intel, confirm that both are top-tier parts in the broader CPU landscape despite their very different design targets.
