AMD Ryzen AI Max+ 388 vs Intel Core Ultra 9 285T Comparison

Head-to-Head Benchmarks

The benchmark data records 15 head-to-head comparisons between the Intel Core Ultra 9 285T and the AMD Ryzen AI Max+ 388. The Intel part wins 13 of those tests, while the AMD part wins 2. The margin of victory, however, varies dramatically by workload type.

The most decisive Intel win comes in Cinebench R23 single-core, where the Core Ultra 9 285T scores 4739 against the Ryzen AI Max+ 388's 1960, a 141.8% advantage. This is the largest delta in the entire comparison. The Cinebench R15 single-core test tells a similar story: 477 versus 298, a 60.1% lead for Intel. These results indicate a substantial per-thread performance gap that carries across generations of the Cinebench suite.

Multi-core rendering also favors Intel, though the gap is smaller. In Cinebench R23 multi-core, the Core Ultra 9 285T scores 33573 versus 18759, a 79% lead. Cinebench R15 multi-core shows 3384 versus 2872, a 17.8% edge. The difference in these two deltas suggests that the Intel part scales better as the workload becomes more demanding, likely due to its higher core count.

The PassMark suite reveals a more nuanced picture. Intel wins floating point math by a wide margin: 137923 versus 72722, an 89.7% advantage. It also leads in find prime numbers by 137.9% (345 versus 145) and in data encryption by 59.6% (32061 versus 20092). Physics testing shows a 54.2% lead (2842 versus 1843). Integer math favors Intel by 20.8% (132433 versus 109588), and multithread performance is 19.2% higher (39931 versus 33486). Random string sorting is closer at 10.4% (47695 versus 43196), and single-thread performance is 9.3% ahead (4576 versus 4185).

The AMD Ryzen AI Max+ 388 wins the remaining two tests. Data compression is its largest victory: 400887 versus 384140, a 4.2% lead. Extended instructions also go to AMD, with a score of 32719 versus 27477, a 16% advantage. These two wins indicate that the AMD part has specific strengths in compression workloads and in extended instruction set execution, areas where its architecture appears better optimized.

The average benchmark score in the database places the Intel part at 51310, while the AMD part sits at 49796. The Intel chip also holds a slightly higher percentile rank among all CPUs at 91, versus 90 for the AMD chip. When placed against their nearest rivals, the Intel Core Ultra 9 285T is 0.6% ahead of the Intel Core i9-14900T, 1.1% ahead of the Intel Core i7-13850HX, and 1.2% ahead of the AMD Ryzen 9 5900XT. It trails the Intel Core i9-13900F by 0.8%. The AMD Ryzen AI Max+ 388 is 0.8% ahead of the Intel Core i5-14600KF, 1.2% ahead of the AMD Ryzen 9 7900, and 1.2% ahead of the AMD Ryzen 7 PRO 5755G. It trails the Intel Core 9 273PE by 0.1%.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 9 285T is built on Arrow Lake architecture with a 3 nm process node from TSMC, while the AMD Ryzen AI Max+ 388 uses Zen 5 architecture on a 4 nm TSMC node. The Intel chip is a desktop part in the Core Ultra Series 2 family, whereas the AMD chip is a mobile part under the Ryzen AI Max series with the Strix Halo codename.

Core and thread counts differ sharply. The Intel part has 24 cores and 24 threads, indicating no hyperthreading. The AMD part has 8 cores and 16 threads, which means simultaneous multithreading is enabled. This core count disparity explains much of the multi-core benchmark behavior. The Intel chip also has a larger L3 cache at 36 MB shared, compared to 32 MB shared on the AMD chip. Per-core L1 and L2 caches are larger on the Intel side as well: 192 KB L1 per core and 3 MB L2 per core, versus 80 KB L1 and 1 MB L2 per core on AMD.

Clock speeds tell a mixed story. The AMD part has a higher base clock at 3.60 GHz versus 1.40 GHz for Intel. The Intel part, however, reaches a higher boost clock at 5.40 GHz versus 5.00 GHz for AMD. Thermal design power also differs: the Intel chip is rated at 35 W, while the AMD chip draws 55 W. The Intel chip is the larger silicon, with a die size of 243 mm² and 17,800 million transistors. The AMD chip uses a dual-die design with two 70.6 mm² dies, and its transistor count is not recorded in the database.

Memory architecture is another major divergence. Intel supports DDR5 with a dual-channel memory bus and 102.4 GB/s bandwidth. AMD supports LPDDR5X with a quad-channel bus and 256.0 GB/s bandwidth, exactly double the Intel figure. Both support ECC memory. PCIe connectivity also differs: Intel offers Gen 5 with 20 CPU lanes, while AMD offers Gen 4 with 16 CPU lanes.

Integrated graphics are present on both parts but differ in branding. Intel uses Arc Xe-LPG Graphics with 64 execution units. AMD uses the Radeon 8060S. The sockets are incompatible: Intel uses Socket 1851, AMD uses Socket FP11. Neither chip has an unlocked multiplier. The Intel part carries the part number SRQD3, while the AMD part is numbered 100-000001980. The Intel chip was released in January 2025, while the AMD chip is dated January 2026 in the database. The Intel part has a launch MSRP of $549; no launch MSRP is recorded for the AMD part.

Where Each One Wins

The Intel Core Ultra 9 285T is the clear choice for rendering workloads. Its Cinebench R23 multi-core score of 33573 is 79% higher than the AMD chip's 18759, and its R15 multi-core score is 17.8% higher. For users running 3D rendering, video encoding, or other heavily threaded content creation tasks, the data strongly favors Intel.

Single-thread performance is also an Intel strength. The 141.8% lead in Cinebench R23 single-core and the 60.1% lead in R15 single-core indicate that applications relying on per-core speed, such as older games or lightly threaded productivity software, will run noticeably better on the Intel part. The PassMark single-thread score confirms this trend at 4576 versus 4185, a 9.3% edge.

Math-heavy workloads favor Intel. Floating point math shows an 89.7% advantage, integer math shows 20.8%, and prime number finding shows 137.9%. Data encryption also goes to Intel by 59.6%. Physics simulation, which often combines math and threading, favors Intel by 54.2%. The multithread PassMark score adds another 19.2% to Intel's column.

The AMD Ryzen AI Max+ 388 wins in two specific areas. Data compression is one: its score of 400887 beats Intel's 384140 by 4.2%. This makes it the better option for file archiving, backup tools, and databases that compress data on the fly. Extended instructions are the other AMD win, with a 16% advantage. Workloads that leverage AVX-512 or similar extended instruction sets may see better throughput on the AMD chip, despite its lower core count.

The AMD chip also offers double the memory bandwidth at 256.0 GB/s versus 102.4 GB/s. While this does not appear in the benchmark scores directly, it suggests that memory-bandwidth-sensitive tasks such as large dataset manipulation or certain scientific computations could behave differently in practice. The quad-channel LPDDR5X memory bus is a structural advantage that the recorded benchmarks may not fully capture.

The Verdict

The benchmark data points to a straightforward conclusion for most workloads. The Intel Core Ultra 9 285T is the superior processor in 13 of 15 recorded tests, with particularly large margins in rendering, single-thread performance, and math workloads. Its 79% lead in Cinebench R23 multi-core and 141.8% lead in R23 single-core make it the default recommendation for users whose priorities align with those tests. The 35 W TDP rating adds to its appeal for systems where power efficiency matters alongside performance.

The AMD Ryzen AI Max+ 388 has a narrower set of advantages. Its wins in data compression and extended instructions are real but limited in scope. Its double memory bandwidth and quad-channel bus are structural advantages that could benefit certain memory-intensive tasks, but the recorded benchmarks do not show those benefits translating into broad performance wins. Its 8-core, 16-thread configuration places it at a significant disadvantage in heavily threaded workloads.

Users who run rendering, compilation, scientific computing, or general productivity software should choose the Intel part based on the recorded data. Users whose workloads specifically involve data compression or extended instruction set execution may find the AMD part competitive, but the overall benchmark record favors Intel by a wide margin. The Intel chip also holds a higher average benchmark score at 51310 versus 49796, and a higher percentile rank at 91 versus 90. For most use cases, the Intel Core Ultra 9 285T is the stronger processor.
