AMD Ryzen 5 7600X3D vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the Intel Core Ultra 9 285. Out of the 17 head-to-head benchmark comparisons, the Intel part wins 17, with the AMD Ryzen 5 7600X3D taking zero. The margin is not uniform, however, and the distribution of deltas reveals where each architecture is strongest and weakest.

The largest Intel advantage appears in floating-point math. In the PassMark floating point test, the Core Ultra 9 285 scores 194,988 against 44,289 for the Ryzen 5 7600X3D, a delta of -77.3% from the AMD part's perspective. That is the single biggest gap in the entire comparison. Data encryption shows a similar trend, with Intel at 46,949 versus AMD at 16,237, a -65.4% difference. These two tests indicate a substantial advantage in compute-heavy, parallel workloads.

The smallest gap is in the PassMark physics test. Intel scores 3,598, AMD scores 2,906, and the delta is only -19.2%. That is still a clear Intel win, but it is far closer than the floating-point result. Single-thread performance also shows a relatively modest gap: 4,881 for Intel versus 3,605 for AMD in PassMark single-thread, a -26.1% difference. The Cinebench single-core tests tell a similar story, with Intel ahead by -55.6% in R15, R20, and R23 single-core, which is a much larger margin than the PassMark single-thread test suggests.

The multi-core Cinebench results are consistently around -55.5% in Intel's favor. In Cinebench R23 multi-core, Intel scores 48,945 against AMD's 21,758. The R20 multi-core result is 20,556 versus 9,138, and R15 multi-core is 4,933 versus 2,193. These are large, consistent deltas that track closely with the core count difference.

PassMark multi-thread shows Intel at 56,602 versus AMD at 25,855, a -54.3% gap. Integer math is nearly identical in relative terms: 164,869 versus 73,804, a -55.2% difference. The extended instructions test shows a -53.5% delta (45,357 versus 21,108), and random string sorting is -53.4% (73,651 versus 34,318). Data compression is -53.2% (602,121 versus 281,665). The only test with a delta below 49% is find prime numbers, where Intel leads 459 to 234, a -49% gap.

The pattern is clear: the Intel part wins every test, but the margin is smallest in physics and single-thread workloads, and largest in floating-point and encryption. The AMD part never comes within 19% of Intel in any recorded test.

Where Each One Wins

The Intel Core Ultra 9 285 wins every recorded benchmark, so the use-case split is not about one part beating the other in a specific test. Instead, the data shows where the Intel advantage is largest and where the AMD part is least disadvantaged.

The AMD Ryzen 5 7600X3D is closest to Intel in the PassMark physics test, with only a -19.2% gap. It is also relatively competitive in PassMark single-thread performance at -26.1%. If the workload is light-threaded or physics-based, the AMD part trails by a smaller margin than in heavy parallel compute. That said, it still trails.

The Intel part dominates in every multi-threaded and compute-heavy test. Floating-point math shows a -77.3% gap, data encryption -65.4%, and multi-core Cinebench results all sit near -55.5%. For rendering, encryption, compression, or any workload that scales across many cores, the Intel part is decisively ahead. The PassMark multi-thread score of 56,602 versus 25,855 confirms that the Intel part delivers more than double the throughput in that test.

The single-thread story is mixed. PassMark single-thread shows a -26.1% delta, which is modest. But Cinebench single-core tests show a -55.6% delta, which is large. The Intel part wins both, but the PassMark result suggests that in some single-threaded tasks, the AMD part is closer than the Cinebench numbers imply.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen 5 7600X3D has 6 cores and 12 threads, while the Intel Core Ultra 9 285 has 24 cores and 24 threads. The Intel part does not use simultaneous multithreading, so thread count equals core count. The AMD part doubles its threads through SMT.

Base clocks differ substantially: AMD runs at 4.10 GHz, Intel at 2.50 GHz. Boost clocks flip the comparison: AMD boosts to 4.70 GHz, Intel to 5.60 GHz. Both have a 65 W TDP.

The socket and platform are completely different. AMD uses Socket AM5, Intel uses Socket 1851. The AMD part uses the 7000 series with the Raphael codename, while Intel is in the Core Ultra Series 2 with the Arrow Lake-S codename.

Memory support is DDR5 for both, and both use a dual-channel memory bus. Memory bandwidth differs: AMD lists 83.2 GB/s, Intel lists 102.4 GB/s. Both support ECC memory.

PCIe configuration differs. AMD offers Gen 5 with 24 lanes from the CPU, Intel offers Gen 5 with 20 lanes. Integrated graphics also differ: AMD has Radeon Graphics, Intel has Arc Xe-LPG Graphics 64EU.

The Intel part has a higher launch MSRP of $579, while the AMD part launched at $299. Both are listed as Active production status. The AMD part launched on 2024-08-29, the Intel part on 2024-12-31. Neither has an unlocked multiplier.

Architecture Differences

The process nodes differ by two generations. The AMD Ryzen 5 7600X3D uses a 5 nm process from TSMC, with 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 9 285 uses a 3 nm process from TSMC, with 17,800 million transistors on a 243 mm² die. The Intel die is more than three times larger, and the transistor count is roughly 58% higher.

Cache architecture is fundamentally different. The AMD part uses Zen 4 with a 96 MB shared L3 cache. Per-core L1 is 64 KB, per-core L2 is 1 MB. The Intel part uses Arrow Lake with a 36 MB shared L3 cache. Per-core L1 is 192 KB, per-core L2 is 3 MB. The AMD part has a much larger L3, while the Intel part has larger per-core L1 and L2 caches.

The core architecture differs in design philosophy. AMD uses Zen 4 with symmetric cores, where all 6 cores are identical and support SMT. Intel uses Arrow Lake with 24 cores and no SMT, meaning 24 threads from 24 physical cores. The Intel part's boost clock of 5.60 GHz is higher than AMD's 4.70 GHz, which contributes to its single-thread advantage in Cinebench.

The Intel part uses a newer process node and a larger die, which explains its higher transistor count. The AMD part uses a smaller die with a much larger L3 cache, which is characteristic of the X3D line. The Intel part has a higher memory bandwidth figure, and the AMD part has more PCIe lanes from the CPU.

The Verdict

The data is unambiguous. The Intel Core Ultra 9 285 wins all 17 head-to-head benchmarks, with an average benchmark score of 75,488 versus 24,728 for the AMD Ryzen 5 7600X3D. The Intel part sits in the 95th percentile of all CPUs, while the AMD part sits in the 77th percentile.

The Intel part is the choice for multi-threaded workloads. Its 24 cores and 24 threads deliver more than double the PassMark multi-thread score and consistently lead Cinebench multi-core tests by about -55.5%. For rendering, encryption, compression, and floating-point math, the Intel part is decisively ahead. The floating-point gap of -77.3% is the largest in the dataset.

The AMD part is the choice only in a relative sense. It is least disadvantaged in physics workloads, where the gap is -19.2%, and in PassMark single-thread, where the gap is -26.1%. It also has a 96 MB shared L3 cache, which is larger than Intel's 36 MB, and a higher base clock of 4.10 GHz. For lightly threaded tasks, the AMD part trails by a smaller margin.

The Intel part has a higher launch MSRP of $579, compared to AMD's $299. It also has a higher boost clock of 5.60 GHz, a larger die, more transistors, and a newer 3 nm process. The AMD part uses a smaller 5 nm process with a much larger L3 cache and more PCIe lanes.

For any workload that scales across cores, the Intel Core Ultra 9 285 is the clear choice from the recorded data. For single-threaded or physics-based tasks, the AMD Ryzen 5 7600X3D is closer, but it still loses every test. The benchmark results do not show any scenario where the AMD part wins. The Intel part is faster in every measured category.
