AMD EPYC 7F72 vs Intel Core Ultra 9 285HX Comparison

The Intel Core Ultra 9 285HX and AMD EPYC 7F72 are both 24-core processors, but they occupy opposite ends of the computing spectrum: the former is a mobile flagship with a 55 W TDP and a 5.5 GHz boost clock, while the latter is a server/workstation part rated at 240 W with a 3.7 GHz boost. Despite these divergent designs, their average benchmark scores are nearly identical—85,124 for the Intel versus 85,072 for the AMD, a 0.1% gap—and both sit in the 97th percentile of all CPUs. In head-to-head testing, the Intel chip wins 12 of 17 benchmarks, while the EPYC takes 5. The data reveals a clear workload split: Intel dominates in floating-point and single-threaded tasks, while AMD leads in integer, memory-throughput, and physics workloads. This analysis examines where each processor excels, what the numbers mean for real-world applications, and which architecture is better suited for specific use cases.

Where Each One Wins

The Intel Core Ultra 9 285HX secures wins across every Cinebench iteration—R15, R20, and R23—in both single-core and multicore tests, with deltas consistently around 18.2–18.4%. For example, Cinebench R23 multicore yields 53,000 for Intel versus 44,829 for AMD, an 18.2% advantage. This pattern indicates a substantial lead in rendering and CPU-intensive productivity tasks. In Passmark, Intel also wins extended instructions (54,810 vs 46,936, +16.8%), floating point math (210,220 vs 108,437, +93.9%), multithread (62,297 vs 52,740, +18.1%), single-thread (4,784 vs 2,384, +100.7%), and find prime numbers (503 vs 498, +1%). The single-thread result is particularly striking—Intel’s score is more than double that of the EPYC, reflecting its higher boost clock and modern 3 nm process.

The AMD EPYC 7F72 claims victory in five benchmarks, all of which are memory-sensitive or integer-heavy. Its data compression score is 808,795 versus Intel’s 709,118, a 12.3% lead. Data encryption shows a narrower margin: 56,261 vs 53,869, a 4.3% advantage. Integer math goes to AMD at 181,103 vs 163,213, a 9.9% win. The largest AMD victory is in physics, where it scores 6,459 against Intel’s 3,970, a 38.5% gap. Random string sorting also favors AMD: 102,436 vs 87,568, a 14.5% difference. These wins align with the EPYC’s hardware: a 192 MB shared L3 cache (versus Intel’s 36 MB) and eight-channel DDR4 memory with 204.8 GB/s bandwidth (versus Intel’s dual-channel DDR5 at 102.4 GB/s). The cache and memory advantages likely drive the compression, sorting, and physics outcomes.

The overall split is unambiguous. Intel owns floating-point arithmetic, single-threaded responsiveness, and multi-threaded rendering. AMD owns integer-heavy data processing, memory-bandwidth-bound tasks, and physics simulation. Neither part is a universal winner; the choice depends entirely on the workload mix.

The Verdict

For users who prioritize rendering, scientific simulation, or any application that relies heavily on floating-point math, the Intel Core Ultra 9 285HX is the superior choice. Its Cinebench scores are consistently 18% higher across all versions, and its Passmark floating-point score is 93.9% above the EPYC’s. Single-threaded performance is nearly double, making the Intel chip ideal for legacy software or lightly threaded code. The 12–5 win count in head-to-head benchmarks further underscores its broader computational strength.

For data-center or workstation roles that involve heavy data compression, encryption, integer math, or physics, the AMD EPYC 7F72 holds a clear edge. Its physics score is 38.5% higher, and it wins data compression by 12.3% and integer math by 9.9%. The EPYC’s 48 threads (versus Intel’s 24) might suggest an advantage in multi-threaded server tasks, but the data shows the opposite: Intel wins the Passmark multithread benchmark by 18.1% despite having half the threads. This indicates that clock speed and architecture efficiency outweigh raw thread count in this comparison.

Given the near-identical average benchmark scores—a 0.1% difference—the decision hinges on specific workloads. The Intel part also operates at a fraction of the EPYC’s power envelope (55 W vs 240 W), which is a critical factor for mobile or power-constrained deployments. The EPYC’s server socket and eight-channel memory make it a better fit for memory-hungry enterprise applications, but the Intel chip’s modern 3 nm process and higher clocks give it a decisive advantage in most general compute scenarios. Both processors are 97th-percentile performers, but they serve different masters.

Head-to-Head Benchmarks

The most lopsided Intel victories come in single-thread and floating-point tests. Passmark single-thread shows 4,784 for Intel versus 2,384 for AMD—a 100.7% advantage, the largest delta
