AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 5 245K Comparison

The Verdict

The database comparison between the AMD Ryzen Embedded 9900X3D and the Intel Core Ultra 5 245K presents a clear split based on workload characteristics. The Intel Core Ultra 5 245K holds a substantial advantage in the recorded benchmark data, achieving an average benchmark score of 54053 and ranking in the 91st percentile of all CPUs. The AMD Ryzen Embedded 9900X3D, by contrast, shows no recorded benchmark scores and sits in the 50th percentile, with an average benchmark score of 0.

The Intel Core Ultra 5 245K delivers its strongest showings in multi-threaded productivity tasks. Its Cinebench R23 multi-core score of 25066 and PassMark multi-thread score of 43047 indicate robust parallel processing capability. The chip also demonstrates strong single-core performance with a Cinebench R23 single-core score of 2132 and a PassMark single-thread score of 4714. These results position the 245K as the more complete processor for users who need consistent performance across both lightly threaded and heavily threaded applications.

The AMD Ryzen Embedded 9900X3D lacks any benchmark entries in the database, meaning no direct performance measurements are available for comparison. Its specifications, including 12 cores, 24 threads, and 128 MB of L3 cache, suggest substantial capability, particularly in cache-sensitive workloads. However, without recorded scores, the data cannot substantiate any performance claims. The Intel part is the only one with measurable results, and those results place it firmly ahead of its nearest rivals, including a 0.7% edge over the Intel Xeon 6505P and a 0.8% edge over the Intel Core i7-14700F. The AMD Ryzen 9 9900X3D sits 1.3% ahead of the 245K in average score, but that comparison uses a different AMD part, not the Embedded 9900X3D analyzed here.

Where Each One Wins

The Intel Core Ultra 5 245K wins every category with recorded data. Its Cinebench R15 multi-core score of 3850 and single-core score of 322 show balanced performance across both test types. The Cinebench R20 results continue this trend, with 15368 multi-core and 2169 single-core. The R23 scores of 25066 multi-core and 2132 single-core reinforce the pattern.

In PassMark tests, the 245K shows specific strengths. The data compression score of 458817 is particularly high, suggesting strong throughput in data-dense operations. The extended instructions score of 37617 and floating point math score of 130678 indicate solid computational breadth. Integer math finishes at 98524, while the find prime numbers test returns 414. The random string sorting score of 55098 demonstrates efficient memory access patterns. Physics simulation scores 3081.

The AMD Ryzen Embedded 9900X3D has no benchmark wins because no benchmark data exists in the database. Its specification sheet shows 12 cores and 24 threads versus the Intel part's 14 cores and 14 threads. The AMD chip also carries 128 MB of L3 cache compared to 24 MB on the Intel side. These numbers suggest the AMD processor could excel in cache-heavy workloads, but the database contains no measurements to confirm such behavior. Users choosing between these two processors on documented performance should select the Intel Core Ultra 5 245K.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X3D belongs to the 9000 series and uses the Granite Ridge codename, built on the Zen 5 architecture. It is manufactured on a 4 nm process at TSMC and contains 16,630 million transistors across a dual-die design with each die measuring 70.6 mm². The chip fits into AMD Socket AM5 and supports PCIe Gen 5 with 24 lanes from the CPU.

The Intel Core Ultra 5 245K is part of the Core Ultra Series 2 and uses the Arrow Lake architecture with the Arrow Lake-S codename. It is built on a 3 nm process at TSMC and contains 17,800 million transistors on a single 243 mm² die. The processor uses Intel Socket 1851 and provides PCIe Gen 5 with 20 lanes from the CPU.

Cache hierarchies differ substantially. The AMD part provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel part offers 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The AMD chip's larger L3 pool gives it a theoretical advantage in workloads that repeatedly access large datasets. The Intel chip's larger per-core L1 and L2 allocations may benefit latency-sensitive single-threaded operations.

Both processors support DDR5 memory in a dual-channel configuration. The AMD chip lists memory bandwidth at 89.6 GB/s, while the Intel chip reaches 102.4 GB/s. Both support ECC memory. The AMD part includes Radeon Graphics as integrated graphics, while the Intel part uses Arc Xe-LPG Graphics with 64 execution units.

The AMD processor releases on 2025-10-06, nearly a year after the Intel chip's 2024-10-23 launch. Both are marked as Active in production status and both have unlocked multipliers. The Intel part carries a launch MSRP of $319, while the AMD part has no listed launch MSRP.
