AMD Ryzen AI Max+ PRO 395 vs Intel Core Ultra 9 285K Comparison

The Intel Core Ultra 9 285K and AMD Ryzen AI Max+ PRO 395 represent two fundamentally different approaches to high-performance computing. The Intel part is a desktop flagship built for maximum throughput, while the AMD chip is a mobile processor designed for efficiency in a compact form factor. Benchmark data shows a decisive overall victory for Intel, with 14 wins against a single win for AMD across the shared test suite, yet the AMD processor’s one victory highlights a specific area where its architecture excels.

Where Each One Wins

The Intel Core Ultra 9 285K is the clear winner in almost every measured category, particularly in tasks that stress raw computational throughput. The data shows a dominant performance in floating-point mathematics, where the Intel chip scores 224324 compared to AMD's 120533, a massive 86.1% advantage. This advantage extends to prime number calculation, where Intel leads by 90.5% (541 vs 284), indicating superior single-threaded integer performance. For content creation workloads, the Intel processor is also ahead: in Cinebench R23 multi-core, it scores 42522 versus AMD's 35061, a 21.3% lead, and in the single-core test it wins by 18.1% (2377 vs 2012.5). Data compression and encryption tasks similarly favor Intel, with leads of 23.6% and 75.8% respectively.

The AMD Ryzen AI Max+ PRO 395 secures only a single head-to-head win, but it is a notable one. In PassMark's integer math test, the AMD chip scores 190720 against Intel's 172379, a 9.6% advantage. This suggests that for specific integer-heavy workloads, the AMD architecture's design provides a measurable benefit. However, this lone victory does little to offset Intel's overall dominance across the broader benchmark suite. Intel also wins the multi-thread test by 30.6% (67260 vs 51502) and random string sorting by 35.3% (94927 vs 70150), reinforcing its position as the superior choice for general multi-core and memory-intensive tasks.

Architecture Differences

The architectural split between these two processors is stark. The Intel Core Ultra 9 285K is built on Arrow Lake-S, utilizing a 3 nm process from TSMC. It features 24 cores and 24 threads, indicating a design without hyper-threading. The processor has a base clock of 3.70 GHz and a boost clock of 5.70 GHz. Its cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and a shared 36 MB L3 cache. It supports dual-channel DDR5 memory with a bandwidth of 102.4 GB/s and offers PCIe Gen 5 with 20 CPU lanes.

In contrast, the AMD Ryzen AI Max+ PRO 395 uses the Zen 5 architecture on a 4 nm TSMC process. It has 16 cores and 32 threads, leveraging simultaneous multithreading. Clocks are lower, with a base of 3.00 GHz and a boost of 5.10 GHz. The cache layout is notably different: 80 KB of L1 per core, 1 MB of L2 per core, and a much larger 64 MB shared L3 cache. Memory support is LPDDR5X via a quad-channel bus, offering a significantly higher bandwidth of 256.0 GB/s. The AMD chip also features PCIe Gen 4 with 16 lanes. These differences in core count, cache size, and memory bandwidth are central to understanding the performance results.

The process node difference (3 nm for Intel vs 4 nm for AMD) and the memory bandwidth disparity (256.0 GB/s vs 102.4 GB/s) are the most significant architectural contrasts. While AMD provides more L3 cache and memory bandwidth, Intel’s higher core count and clock speeds appear to be more impactful in the majority of benchmarks. The Intel chip also has a TDP of 125W, while the AMD part is rated at just 55W, indicating a major difference in power envelope and target use case.

Head-to-Head Benchmarks

The benchmark results are heavily skewed toward the Intel Core Ultra 9 285K, but the margin of victory varies significantly by workload. The most lopsided results are in PassMark's floating-point math and prime number tests. In floating-point math, Intel's score of 224324 is a staggering 86.1% higher than AMD's 120533. Similarly, in the find prime numbers test, Intel scores 541 against AMD's 284, a 90.5% lead. These results indicate that for scientific or financial computing tasks that rely on such operations, the Intel chip is in a different league entirely.

The Cinebench tests, which are standard for rendering workloads, also show a consistent Intel advantage. In the R23 multi-core test, Intel leads by 21.3% (42522 vs 35061). The single-core R23 test shows an 18.1% lead for Intel (2377 vs 2012.5). The older R15 versions of these tests show similar margins, with Intel winning multi-core by 23.8% and single-core by 17.3%. This consistency across generations of the benchmark suggests a fundamental performance advantage in both single-threaded and multi-threaded rendering scenarios.

In the PassMark suite, Intel wins data compression by 23.6% and data encryption by a massive 75.8% (57745 vs 32840). The multi-thread test shows a 30.6% lead for Intel (67260 vs 51502), while the single-thread test shows a 24.7% advantage (5087 vs 4078). The physics test is also won by Intel, with a 23.5% margin. The only bright spot for AMD is the integer math test, where it scores 190720 versus Intel's 172379, a 9.6% win. This single result shows the Zen 5 architecture has specific strengths, but they are isolated to a narrow set of operations. Overall, the data paints a picture of an Intel processor that is faster across nearly all computational areas, with AMD's main advantages lying in memory bandwidth and power efficiency rather than raw benchmark performance.
