AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 7 256V Comparison

The Verdict

The database records two processors aimed at entirely different computing environments. The AMD Ryzen Embedded 9900X3D is a 12-core, 24-thread desktop part built for the AMD Socket AM5 with a 120 TDP, while the Intel Core Ultra 7 256V is an 8-core, 8-thread mobile processor with a 17 TDP soldered to Intel BGA 2833. The data shows the Intel part holds a 75th percentile ranking across all CPUs in the database, whereas the AMD part sits at the 50th percentile. However, the AMD processor has no recorded benchmark scores in the database, which means its percentile ranking does not reflect any measured performance data.

The Intel Core Ultra 7 256V has a substantial body of benchmark results: a Cinebench R23 multi-core score of 10399, a single-core score of 1877.5, a Geekbench multi-core score of 8643, and a Geekbench single-core score of 1990. Its average benchmark score across all recorded tests is 21112. The AMD Ryzen Embedded 9900X3D has an average benchmark score of zero and no benchmark entries. This makes direct performance comparison impossible from the recorded data. The Intel part delivers measurable results across every test in the database, while the AMD part contributes no scores.

The AMD processor targets a desktop workstation environment with a 120 TDP, 24 PCIe Gen 5 lanes from the CPU, and ECC memory support. The Intel processor targets mobile computing with a 17 TDP, only 4 PCIe Gen 5 lanes from the CPU, and no ECC memory support. The AMD part has an unlocked multiplier, enabling overclocking, while the Intel part is locked. The AMD part also uses a 4 nm TSMC process with a 16,630 million transistor count across a dual 70.6 mm² die configuration, while the Intel part uses a 3 nm TSMC process with no transistor or die size data recorded.

For a buyer strictly consulting the database, the Intel Core Ultra 7 256V is the only one of the two with verifiable performance metrics. The AMD Ryzen Embedded 9900X3D offers more cores, more threads, a higher base clock of 4.40 GHz, a higher boost clock of 5.50 GHz, and a larger L3 cache of 128 MB, but none of that translates into recorded benchmark scores. The Intel part delivers a lower base clock of 2.20 GHz and a lower boost clock of 4.80 GHz, yet it has a 75th percentile ranking based on its measured results.

The decision rests on which data points matter. The AMD part is for a system builder who needs a 12-core processor with ECC memory, an unlocked multiplier, and 24 PCIe Gen 5 lanes in a desktop socket. The Intel part is for a mobile system builder who needs an 8-core processor with a 17 TDP, integrated Arc 140V graphics, and recorded performance numbers that place it in the 75th percentile of all CPUs. The data does not support a performance winner because the AMD part has no benchmark scores. The Intel part stands as the only processor in this comparison with any measured performance evidence.
