AMD Ryzen Embedded 9700X vs Intel Core Ultra 9 285K Comparison

The Verdict

The Intel Core Ultra 9 285K is the dominant processor in this comparison, holding the 96th percentile among all CPUs in the database with an average benchmark score of 83,807. The AMD Ryzen Embedded 9700X sits at the 50th percentile with an average benchmark score of 0, which reflects that no benchmark results have been recorded for it in the database. The Intel part is the clear performance leader across every measurable workload, but the AMD processor offers a fundamentally different design philosophy: 8 cores and 16 threads at a 65 W TDP versus 24 cores and 24 threads at a 125 W TDP. The Ryzen Embedded 9700X is a lower-power, higher-efficiency option for embedded deployments, while the Core Ultra 9 285K is a high-throughput desktop part for users who need maximum multi-threaded performance.

The Intel Core Ultra 9 285K carries a launch MSRP of $589. The AMD Ryzen Embedded 9700X has no recorded launch MSRP in the database.

Where Each One Wins

The Intel Core Ultra 9 285K wins every benchmark category in the recorded data. Its multi-threaded scores are exceptional: Cinebench R23 multi-core reaches 42,522, Cinebench R20 multi-core reaches 24,003, and Cinebench R15 multi-core reaches 6,494. Geekbench multi-core lands at 26,702. These numbers place it far above the AMD part, which has no recorded scores to compare against.

The AMD Ryzen Embedded 9700X wins on power efficiency by specification. It draws a 65 W TDP, nearly half the 125 W TDP of the Intel chip, while still offering 8 cores and 16 threads with a boost clock of 5.50 GHz. The AMD part also provides more PCIe lanes from the CPU: 24 Gen 5 lanes versus 20 Gen 5 lanes for Intel. For embedded systems where thermal headroom and board connectivity matter more than raw compute, the AMD processor is the more practical choice. The Intel chip wins outright in performance, but the AMD chip wins on the metrics that matter in constrained environments: lower power draw and wider PCIe connectivity.

Architecture Differences

The two processors come from different architectural lineages. AMD uses the Granite Ridge codename with Zen 5 (Granite Ridge) generation technology, built on a 4 nm TSMC process. Intel uses the Arrow Lake-S codename with Arrow Lake generation technology, built on a 3 nm TSMC process. The transistor counts differ substantially: AMD packs 8,315 million transistors on a 70.6 mm² die, while Intel packs 17,800 million transistors on a 243 mm² die. The Intel die is more than three times larger in area and holds more than twice the transistor count.

Core configurations diverge sharply. The AMD part has 8 cores and 16 threads with 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Intel part has 24 cores and 24 threads with 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. Intel does not use simultaneous multi-threading, which is why 24 cores produce exactly 24 threads. AMD relies on SMT to double its thread count from 8 to 16.

Clock speeds are close. AMD has a base clock of 3.80 GHz and a boost clock of 5.50 GHz. Intel has a base clock of 3.70 GHz and a boost clock of 5.70 GHz. Intel holds a 200 MHz advantage at boost.

Memory support is DDR5 for both, with dual-channel buses. Intel has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for AMD. Both support ECC memory. Integrated graphics differ: AMD includes Radeon Graphics, while Intel includes Arc Xe-LPG Graphics 64EU. Both processors have unlocked multipliers. The Intel part was released on 2024-10-23, while the AMD part followed on 2025-10-06.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the AMD Ryzen Embedded 9700X has no individual benchmark scores recorded. The Intel Core Ultra 9 285K, however, has a full suite of 19 recorded benchmark results that establish its performance envelope.

Starting with multi-threaded rendering workloads, the Intel chip scores 42,522 in Cinebench R23 multi-core, 24,003 in Cinebench R20 multi-core, and 6,494 in Cinebench R15 multi-core. Single-core results are 2,377 in Cinebench R23, 3,388 in Cinebench R20, and 359 in Cinebench R15. Geekbench results show 26,702 in multi-core and 2,870 in single-core.

PassMark workloads give a broader view of the Intel part's strengths. The multithread score is 67,260, and the single-thread score is 5,087. Integer math scores 172,379, while floating point math scores 224,324. Extended instructions reach 62,277, and data encryption hits 57,745. Data compression is the standout at 790,052. Random string sorting posts 94,927, and physics scores 3,938. Prime number finding scores 541.

The nearest rivals in the database put the Intel chip's standing in context. The Intel Core Ultra 9 290K Plus scores 84,003, which is 0.2% ahead of the 285K. The AMD EPYC 4584PX scores 83,090, which is 0.9% behind. The AMD EPYC 9135 scores 82,980, which is 1% behind. The AMD EPYC 7F72 scores 85,072, which is 1.5% ahead. These deltas show the Core Ultra 9 285K operating in a tight band among high-end server and desktop parts, with all four nearest rivals within 1.5% of its average score.

Because the AMD Ryzen Embedded 9700X has no recorded benchmarks, the head-to-head comparison relies on specification analysis rather than measured scores. The Intel part's 24 cores, 36 MB of L3 cache, and 102.4 GB/s memory bandwidth give it a structural advantage in multi-threaded workloads. The AMD part's 8 cores, 32 MB of L3 cache, and 89.6 GB/s memory bandwidth indicate a more modest throughput ceiling. The 65 W TDP of the AMD part suggests it will sustain lower performance but with far less power draw.

The Intel part's production status is Active, and its part number is SRQD5. The AMD part's production status is also Active, with part number 100-000001404E. Both are current products in the database.
