AMD Ryzen AI 9 HX 370 vs Intel Core i9-12900T Comparison

Head-to-Head Benchmarks

The recorded data presents a fascinating split between these two processors. Across seventeen head-to-head benchmark comparisons, the AMD Ryzen AI 9 HX 370 claims fourteen wins, while the Intel Core i9-12900T takes three. But the magnitude of those wins tells a more nuanced story than the raw count suggests.

The Intel part's most dramatic victory comes in Cinebench R23 single-core, where it scores 3462 against AMD's 2018, a commanding 71.6% advantage. That is not a marginal lead; it is a generational gap in single-threaded performance. The i9-12900T also wins Cinebench R23 multi-core with 24528 versus 21761, a 12.7% edge, and Cinebench R15 single-core at 348 versus 306.5, a 13.5% margin. These are the classic rendering workloads where Intel's hybrid architecture appears to flex its muscles.

The AMD chip responds with its own decisive victories elsewhere. In Geekbench multi-core, the Ryzen AI 9 HX 370 scores 15242 against Intel's 11615, a 23.8% lead. Cinebench R15 multi-core shows an even larger gap: AMD scores 3409.5 versus 2472, a 27.5% advantage. The PassMark extended instructions test is particularly lopsided, with AMD at 31653 versus Intel at 20054, a 36.6% difference. That test measures SIMD and specialized instruction throughput, and the Zen 5 architecture clearly dominates there.

The remaining AMD wins are smaller but consistent. PassMark data compression shows AMD ahead by 22.6% (445719 versus 345021), random string sorting by 18.4% (48723 versus 39771), and multithread by 15.8% (35148 versus 29601). Integer math favors AMD by 12% (122933 versus 108211), while encryption, physics, floating point, and single-thread tests show narrower margins ranging from 1.5% to 7.9%. The 3DMark tests, which only appear for AMD, add context: 9725 at max threads and 1153 single-thread, suggesting strong scaling behavior.

What stands out is the asymmetry. Intel wins rendering workloads by large margins, particularly single-threaded Cinebench. AMD wins everything else, sometimes by enormous margins. The average benchmark scores reflect this overall balance: AMD sits at 37904, Intel at 37112, a difference of roughly 2%. Both chips land in the 85th to 86th percentile of all CPUs in the database, so neither is a slouch.

Where Each One Wins

The benchmark results point to distinct use-case strengths. For content creators running Cinebench-style rendering tasks, the Intel Core i9-12900T is the clear choice. Its 71.6% single-core lead in Cinebench R23 and 12.7% multi-core advantage in the same test suggest that workloads heavily reliant on that specific rendering engine will finish noticeably faster on Intel silicon. The 13.5% win in Cinebench R15 single-core reinforces this pattern.

The AMD Ryzen AI 9 HX 370, however, dominates general-purpose computing tasks. Data compression workloads favor AMD by 22.6%, which matters for file archiving, database operations, and any application that shuttles large amounts of data. The 36.6% lead in extended instructions points to scientific computing, cryptography, and media encoding that leverage SIMD operations. Integer math, up 12%, covers everything from office productivity to financial modeling.

The Geekbench results are particularly telling. AMD leads multi-core by 23.8% and single-core by 6.1%. Geekbench is a broader, more representative workload than Cinebench, so this suggests AMD's advantage extends across everyday applications, not just specialized tasks. The PassMark multithread score, up 15.8%, reinforces that AMD handles parallel general workloads better overall.

The physics test, which AMD wins by 3.7%, and floating point math, up 1.5%, are close enough to be considered near-parity. The single-thread PassMark tests show AMD ahead by 4.1%, a modest but consistent edge. For users whose workloads mix rendering with general productivity, the database suggests AMD offers the more balanced profile, with Intel winning the specific rendering niche decisively.

Architecture Differences

The two processors come from fundamentally different design philosophies. Intel's Core i9-12900T uses Alder Lake, a hybrid architecture that combines performance and efficiency cores on a 10 nm process built by Intel itself. The chip implements a 16-core, 24-thread configuration with a 30 MB shared L3 cache. Each core gets 80 KB of L1 and 1.25 MB of L2. The die measures 215 mm².

AMD's Ryzen AI 9 HX 370 uses Zen 5, specifically the Strix Point design, which blends Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC, a significantly denser node than Intel's 10 nm. The chip packs 12 cores and 24 threads into a 233 mm² die, slightly larger than Intel's despite having fewer cores. Each core has 80 KB of L1, but L2 drops to 1 MB per core, and L3 is just 16 MB, nearly half of Intel's 30 MB.

The cache difference is striking. Intel's larger L3 should help with workloads that repeatedly access a working set that fits in cache. AMD's smaller cache, combined with the denser process, suggests a design that prioritizes memory bandwidth instead. AMD lists 89.6 GB/s of memory bandwidth, though Intel's figure is not recorded in the database.

Memory support differs as well. Intel supports both DDR4 and DDR5, giving system builders flexibility with older or newer memory. AMD supports only DDR5 and LPDDR5X, which makes sense for its mobile-focused design. Both use dual-channel memory buses. Neither supports ECC.

The integrated graphics differ substantially. Intel pairs the CPU with UHD Graphics 770, while AMD includes Radeon 890M. The database does not record benchmark scores for either iGPU, so a direct comparison is not possible from this data. AMD's Radeon 890M is generally associated with more capable integrated graphics in mobile parts, but that cannot be confirmed from these measurements.

PCIe support also diverges. Intel offers Gen 5 with 20 CPU lanes, while AMD provides Gen 4 with 16 lanes. For desktop users with high-end GPUs or NVMe drives, Intel's newer PCIe standard could matter. For mobile users, the older standard is likely sufficient.

The process node gap is the most fundamental architectural difference. Intel's 10 nm node, which is denser than the name suggests, cannot match the transistor density of TSMC's 4 nm process. That density advantage likely contributes to AMD's efficiency, though the TDP figures tell a more complex story.

Specification Differences

The two chips differ across nearly every specification category. Intel offers 16 cores and 24 threads, while AMD offers 12 cores and 24 threads. The thread count matches, but Intel has four more physical cores. Intel's base clock is 1400 MHz, AMD's is 2000 MHz, a 600 MHz difference. Boost clocks favor AMD at 5.10 GHz versus Intel's 4.90 GHz.

Power draw diverges significantly. Intel's TDP is 35 watts, while AMD's is 28 watts. The AMD chip draws less power while delivering higher boost clocks, proof of the efficiency of the 4 nm process. The socket types are entirely different: Intel uses Socket 1700, AMD uses Socket FP8. This means no motherboard compatibility between the two.

The process node shows Intel at 10 nm and AMD at 4 nm. Foundries differ as well: Intel fabricates its own chip, while TSMC produces AMD's. Die size is comparable, with Intel at 215 mm² and AMD at 233 mm². Cache configurations differ in L2 and L3: Intel has 1.25 MB L2 per core and 30 MB shared L3, AMD has 1 MB L2 per core and 16 MB L3.

Memory support shows Intel accepting DDR4 and DDR5, AMD accepting DDR5 and LPDDR5X. AMD records 89.6 GB/s memory bandwidth; Intel does not list a bandwidth figure. PCIe capabilities favor Intel with Gen 5 and 20 lanes versus AMD's Gen 4 and 16 lanes. Integrated graphics are UHD Graphics 770 for Intel and Radeon 890M for AMD.

The market segments differ: Intel is a desktop part, AMD is mobile. Release dates show Intel launching on 2022-01-03 and AMD on 2024-06-30, roughly two and a half years apart. Intel has an unlocked multiplier, AMD does not. Intel's launch MSRP is $489, while AMD has no recorded MSRP. Intel's part number is SRL4M, AMD's is 100-000000994.

The Verdict

The data points to two distinct profiles. The Intel Core i9-12900T is the rendering specialist. Its Cinebench R23 single-core score of 3462 is 71.6% ahead of AMD, and its multi-core score of 24528 is 12.7% ahead. Anyone whose primary workload is Cinebench-style rendering should choose Intel without hesitation. The unlocked multiplier and support for both DDR4 and DDR5 add flexibility for desktop builders.

The AMD Ryzen AI 9 HX 370 is the generalist that wins more often than not. It takes fourteen of seventeen head-to-head matchups, with particularly strong showings in Geekbench multi-core (23.8% ahead), data compression (22.6% ahead), and extended instructions (36.6% ahead). Its lower 28 watt TDP, higher 5.10 GHz boost clock, and 86th percentile ranking make it the better all-around choice for mobile users who need strong performance across varied tasks.

For desktop users with rendering-heavy workloads, the Intel part's three wins are the three that matter most. For everyone else, AMD's consistent dominance across the broader benchmark suite makes it the safer recommendation. The average benchmark scores, 37904 versus 37112, put AMD ahead overall, but the margin is small enough that workload-specific needs should drive the decision. The verdict from the database: pick Intel for Cinebench rendering, pick AMD for virtually everything else.
