AMD Ryzen AI 5 PRO 435 vs Intel Core i9-12900T Comparison

Head-to-Head Benchmarks

The benchmark data paints a decisive picture: the Intel Core i9-12900T wins all 11 recorded head-to-head comparisons against the AMD Ryzen AI 5 PRO 435. The most lopsided margins appear in compute-heavy workloads. In Passmark's find prime numbers test, the Intel part scores 116 versus 57 for the AMD, a 50.9% advantage. Floating point math shows a similar gap, with Intel at 75,741 against AMD's 41,114, a 45.7% delta. Integer math follows the same trend: 108,211 versus 60,879, a 43.7% deficit for the AMD chip.

The gap narrows considerably in single-threaded performance. The Intel chip scores 3,810 in Passmark single thread, while the AMD part posts 3,757. That is a mere 1.4% difference, making this the closest contest in the entire dataset. Data encryption also favors Intel heavily, with a score of 20,750 versus 11,267, a 45.7% margin. Extended instructions show a smaller but still significant gap: 20,054 versus 16,724, a 16.6% difference.

Multithreaded performance tells a familiar story. The Intel i9-12900T reaches 29,601 in Passmark multithread, while the AMD Ryzen AI 5 PRO 435 manages 19,091, a 35.5% gap. Physics simulation results are similarly one-sided: 1,811 for Intel versus 995 for AMD, a 45.1% difference. Random string sorting shows Intel ahead at 39,771 versus 24,936, a 37.3% margin. Data compression rounds out the list with Intel at 345,021 and AMD at 232,803, a 32.5% deficit.

The average benchmark scores confirm the hierarchy. The AMD chip posts an average of 37,762, placing it in the 86th percentile of all CPUs. The Intel part averages 37,112, landing in the 85th percentile. Despite the Intel chip winning every head-to-head test, the average scores are remarkably close, differing by less than 2%. This suggests that the AMD processor's strong single-thread showing and efficient architecture keep its overall standing competitive, even though it loses every individual comparison.

Where Each One Wins

The Intel Core i9-12900T is the clear winner across all recorded workloads. Its 16 cores and 24 threads provide substantial advantages in parallel tasks. The data shows Intel ahead by 35.5% in multithreaded throughput, 43.7% in integer math, and 45.7% in floating point math. For users running heavily threaded applications, the Intel part holds a commanding lead.

The AMD Ryzen AI 5 PRO 435, while losing every benchmark, shows its closest performance in single-threaded tasks. The 1.4% gap in Passmark single thread suggests that for lightly threaded workloads, the difference is nearly imperceptible. The AMD chip also demonstrates competitive average scores overall, sitting just 1.7% behind the Intel part in average benchmark score (37,762 versus 37,112). Its 86th percentile ranking versus Intel's 85th indicates that the AMD processor holds its own relative to the broader CPU landscape.

Workloads favoring the Intel chip include data compression, encryption, extended instruction sets, prime number calculations, physics simulations, and random string sorting. The AMD part has no recorded wins, but its single-thread score of 3,757 versus 3,810 means that everyday tasks like web browsing, office productivity, and light coding would show minimal practical differences. The Intel chip's 30 MB of shared L3 cache versus the AMD's 4 MB likely contributes to its data-heavy advantages, though the benchmark data does not isolate cache effects directly.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 5 PRO 435 uses Zen 5 architecture on a 4 nm TSMC process, codenamed Gorgon Point. It belongs to the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. The Intel Core i9-12900T uses Alder Lake architecture on Intel's 10 nm process, codenamed Alder Lake-S. The Intel die measures 215 mm², while the AMD chip has no recorded die size.

Core counts differ sharply. The AMD chip provides 6 cores and 12 threads, while the Intel chip offers 16 cores and 24 threads. Base clocks also diverge: AMD runs at 2.00 GHz, Intel at 1400.00 MHz (the value as recorded). Boost clocks favor Intel slightly, with 4.90 GHz versus 4.50 GHz for AMD. Thermal design power favors AMD, however, with a 28 W TDP versus 35 W for Intel.

Cache hierarchies show notable differences. Both allocate 80 KB of L1 cache per core. The AMD chip has 1 MB of L2 per core, while Intel provides 1.25 MB per core. The L3 cache is the largest discrepancy: Intel offers 30 MB shared, while AMD provides only 4 MB. Memory support also differs: AMD supports DDR5 and LPDDR5X with a recorded bandwidth of 89.6 GB/s, while Intel supports both DDR4 and DDR5 with no recorded bandwidth figure. AMD includes ECC memory support; Intel does not.

PCIe connectivity favors Intel, which provides Gen 5 with 20 lanes, versus AMD's Gen 4 with 14 lanes. Integrated graphics differ as well: AMD uses Radeon 840M, Intel uses UHD Graphics 770. The AMD chip fits an AMD Socket FP8 and targets the mobile segment, while Intel uses Socket 1700 for desktop. The AMD processor is not multiplier unlocked; the Intel chip is. Release dates are distinct: AMD launched on January 4, 2026, while Intel launched on January 3, 2022. Intel lists a launch MSRP of $489; AMD has no recorded launch MSRP.

The Verdict

The data directs different buyers to different chips. The Intel Core i9-12900T wins every recorded benchmark, with particularly large advantages in multithreaded, physics, and floating point workloads. Its 16 cores, 24 threads, and 30 MB of shared L3 cache make it the superior choice for heavy parallel processing, data compression, encryption, and scientific computing. The 45.7% lead in floating point math and 43.7% lead in integer math indicate strong raw compute capability.

The AMD Ryzen AI 5 PRO 435, despite losing all 11 head-to-head tests, presents a more nuanced profile. Its higher average benchmark score (37,762 versus 37,112) and better percentile ranking (86th versus 85th) suggest that its overall standing among all CPUs is slightly stronger. The 1.4% single-thread gap means that general productivity tasks would feel nearly identical. The 28 W TDP versus 35 W makes it more suitable for power-constrained mobile environments.

Users requiring maximum multi-threaded throughput should choose the Intel chip without hesitation. Its 35.5% multithread lead and 50.9% advantage in prime number calculations are decisive. Mobile users prioritizing efficiency and integrated graphics with LPDDR5X support may prefer the AMD chip, especially given its competitive single-thread performance and higher average score. The Intel chip also offers PCIe Gen 5 with 20 lanes versus Gen 4 with 14 lanes, making it better suited for high-bandwidth expansion. The AMD chip supports ECC memory, which Intel does not, a factor for reliability-sensitive workloads. Ultimately, the Intel chip dominates in raw performance, while the AMD chip wins on efficiency and overall benchmark standing.
