AMD Ryzen AI 7 PRO 350 vs Intel Core i9-12900HX Comparison

The AMD Ryzen AI 7 PRO 350 and Intel Core i9-12900HX represent two very different philosophies for high-performance mobile computing: one is a modern, power-efficient 8-core Zen 5 part, while the other is a 16-core Alder Lake flagship designed to push raw throughput. The benchmark data shows a clear split: Intel dominates multi-threaded and heavy compute workloads, while AMD takes the single-thread crown in both Cinebench and Passmark. Across 15 head-to-head tests, the Intel wins 12, but the AMD’s three victories are decisive in the areas that matter most for everyday responsiveness and lightly-threaded tasks.

Where Each One Wins

The Intel Core i9-12900HX is the undisputed king of heavy multi-threaded workloads. Its 16 cores and 24 threads give it a massive structural advantage, and the benchmark results confirm this. In Cinebench R23 multi-core, it scores 23150 against the AMD’s 14278.5, a 38.3% lead. This margin repeats across nearly every Passmark compute test: floating point math (84410 vs 51639, a 38.8% lead), find prime numbers (132 vs 81, a 38.6% lead), and data encryption (22932 vs 14462, a 36.9% lead). If your work involves video rendering, 3D simulation, or any workload that scales across all cores, the Intel is simply in a different league.

The AMD Ryzen AI 7 PRO 350 wins the single-thread efficiency battle. In Cinebench R23 single-core, it scores 1954 versus Intel’s 1912.5 (a 2.2% lead), and in Passmark single-thread, it scores 3872 versus 3745 (a 3.4% lead). These numbers are tight, but they reflect a consistent pattern: the Zen 5 architecture delivers higher per-core performance. This translates to snappier application launches, faster web browsing, and better performance in older or poorly-threaded games and software. The AMD also has a significant power efficiency edge on paper, with a 28W TDP versus Intel’s 55W, suggesting it can sustain its single-thread advantages in thinner, cooler chassis.

FAQ

Q: Which processor is faster in multi-core rendering?

A: The Intel Core i9-12900HX is substantially faster. It leads by 34.5% in Cinebench R15 multi-core (3566 vs 2336.5) and by 38.3% in Cinebench R23 multi-core (23150 vs 14278.5).

Q: Does the AMD chip win any benchmark at all?

A: Yes, it wins three benchmarks. It takes Cinebench R23 single-core (1954 vs 1912.5) and both Passmark single-thread tests (3872 vs 3745 in both cases). It does not win any of the 12 other head-to-head tests.

Q: How do they compare in memory bandwidth?

A: The AMD Ryzen AI 7 PRO 350 has a listed memory bandwidth of 89.6 GB/s with dual-channel DDR5/LPDDR5X support. The Intel Core i9-12900HX does not have a bandwidth figure listed in the data, but it supports dual-channel DDR4 and DDR5.

Q: What is the difference in core and thread counts?

A: The Intel Core i9-12900HX has 16 cores and 24 threads. The AMD Ryzen AI 7 PRO 350 has 8 cores and 16 threads. The Intel part has double the physical cores, which explains its multi-threaded dominance.

Q: Which chip has the better integrated graphics?

A: The AMD Ryzen AI 7 PRO 350 features the Radeon 860M, while the Intel Core i9-12900HX features the UHD Graphics 770. The benchmark data does not include GPU tests, so a direct performance comparison is not possible from this information.

Q: Are both chips unlocked for overclocking?

A: No. The Intel Core i9-12900HX has an unlocked multiplier, while the AMD Ryzen AI 7 PRO 350 does not. This makes the Intel part more appealing to enthusiasts who want to tweak performance.

Head-to-Head Benchmarks

The Cinebench results tell the story of a generational trade-off. In multi-core, the Intel i9-12900HX is a heavyweight. Its Cinebench R23 multi-core score of 23150 crushes the AMD’s 14278.5, a 38.3% gap. The R15 multi-core test shows a similar 34.5% lead (3566 vs 2336.5). These are not marginal wins; they are decisive victories that will translate into dramatically shorter render times. However, the single-core results flip the script. The AMD Ryzen AI 7 PRO 350 scores 1954 in Cinebench R23 single-core, edging out Intel’s 1912.5 by 2.2%. This is a small but important win, as single-core speed is often the bottleneck in everyday use.

The Passmark suite reinforces the Intel’s multi-threaded dominance. In floating point math, Intel scores 84410 against AMD’s 51639, a 38.8% lead. In integer math, Intel’s 113416 beats AMD’s 84868 by 25.2%. Data compression is another Intel win at 400636 vs 281834 (29.7% lead), and data encryption shows Intel at 22932 vs 14462 (36.9% lead). Even random string sorting, which can be sensitive to memory latency, goes to Intel (43877 vs 31071, a 29.2% lead). The only Passmark test AMD wins is single-thread, where its 3872 beats Intel’s 3745 by 3.4%. The physics test also goes to Intel (2012 vs 1318, a 34.5% lead), and extended instructions favor Intel (24315 vs 19955, a 17.9% lead).

Specification Differences

The core configuration is the most obvious divergence. The Intel Core i9-12900HX offers 16 cores and 24 threads, while the AMD Ryzen AI 7 PRO 350 has 8 cores and 16 threads. This is the primary reason for the multi-threaded performance gap. The base clocks differ slightly, with Intel at 2.30 GHz and AMD at 2.00 GHz; both boost to 5.00 GHz. The TDP is a major differentiator: Intel is rated at 55W, while AMD is rated at 28W. This suggests that AMD’s chip is designed for more power-efficient laptops, while Intel’s is geared toward larger, high-performance machines with better cooling.

Memory support also differs. The AMD supports DDR5 and LPDDR5X with a dual-channel bus and a listed bandwidth of 89.6 GB/s. The Intel supports DDR4 and DDR5 with a dual-channel bus, but no bandwidth figure is provided. The AMD has a smaller die size at 195 mm² versus Intel’s 215 mm², and it is manufactured on a 4nm process by TSMC, while Intel uses a 10nm process at its own foundry. The L3 cache is another stark difference: AMD has 8 MB, while Intel has 30 MB shared. The Intel also has more PCIe lanes (20 Gen 5 lanes) versus AMD’s 16 Gen 4 lanes.

Architecture Differences

The architectural philosophies are fundamentally opposed. The AMD Ryzen AI 7 PRO 350 is built on the Zen 5 architecture, specifically the "Krackan Point" codename, and belongs to the Ryzen AI PRO 300 generation that includes both Zen 5 and Zen 5c cores. It is a 4nm TSMC part with a die size of 195 mm². The Intel Core i9-12900HX is based on the older Alder Lake architecture with the "Alder Lake-HX" codename, built on Intel’s 10nm process with a slightly larger 215 mm² die. The Intel uses a hybrid core design, which is not explicitly stated but is implied by its 16 cores and 24 threads.

Cache hierarchies are notably different. Both have 80 KB of L1 per core, but the AMD has 1 MB of L2 per core, while the Intel has 1.25 MB per core. The L3 cache is where they diverge sharply: the AMD has 8 MB, while the Intel has 30 MB shared. This larger L3 cache likely helps Intel in certain data-heavy workloads, but the benchmark data shows AMD still wins in single-thread tests. The AMD also features the Radeon 860M integrated graphics, while Intel uses UHD Graphics 770. The AMD supports ECC memory, and so does the Intel. The Intel has an unlocked multiplier, while the AMD does not.

The Verdict

The choice hinges entirely on your workload. If your primary tasks involve multi-threaded rendering, video encoding, or heavy number-crunching, the Intel Core i9-12900HX is the clear pick. The data shows a 38.3% lead in Cinebench R23 multi-core and a 38.8% lead in floating point math. These are massive advantages that will translate into real time savings. The Intel also offers an unlocked multiplier for overclocking, which the AMD does not.

If your work is more varied and includes a mix of light and heavy tasks, the AMD Ryzen AI 7 PRO 350 is compelling. It wins the single-thread tests, which means faster everyday responsiveness. Its 28W TDP is dramatically lower than Intel’s 55W, making it better suited for thin-and-light laptops with longer battery life. It also has a newer 4nm process and a smaller die, suggesting better power efficiency. The AMD’s win in Cinebench R23 single-core (1954 vs 1912.5) and Passmark single-thread (3872 vs 3745) shows that its per-core performance is superior, even if its total thread count is half. For users who prioritize a snappy, efficient daily driver over raw multi-core muscle, the AMD is the smarter choice. For those who need maximum throughput and do not mind the power draw, the Intel is the definitive answer.
