AMD Ryzen Embedded 9900X vs Intel Core Ultra 5 235T Comparison

The AMD Ryzen Embedded 9900X and the Intel Core Ultra 5 235T are two desktop processors with very different design priorities. The AMD part is a 12-core, 24-thread chip built on a 4 nm process with a 120 W TDP, while the Intel part is a 14-core, 14-thread chip on a 3 nm process with a 65 W TDP. The recorded database contains a full benchmark suite for the Intel processor, but no benchmark scores for the AMD processor, so the quantitative comparison relies on the Intel data and the architectural and specification differences between the two parts.

Where Each One Wins

Based on the available data, the Intel Core Ultra 5 235T is the only processor with recorded benchmark scores, so it holds all measured wins in this comparison. The AMD Ryzen Embedded 9900X has no benchmark entries in the database, meaning there is no measured performance data to place it ahead in any test. The Intel part achieves a percentile of 86 among all CPUs, while the AMD part sits at the 50th percentile, which reflects the absence of test scores rather than a direct measurement of inferior performance.

The use-case split follows the specification differences. The Intel Core Ultra 5 235T has 14 cores and 14 threads, which suits workloads that benefit from many physical cores without relying on simultaneous multithreading. The AMD Ryzen Embedded 9900X has 12 cores and 24 threads, which supports heavily threaded workloads that scale with thread count. The Intel chip has a base clock of 2.20 GHz and a boost clock of 5.00 GHz, while the AMD chip has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The AMD part has a higher TDP at 120 W, which allows for sustained high-frequency operation, while the Intel part uses 65 W and is positioned for lower-power environments.

The recorded benchmarks for the Intel part include Cinebench R15, R20, and R23, plus PassMark tests. The Cinebench R23 multicore score is 26232, and the single-core score is 3703. The PassMark multithread score is 30918, and the single-thread score is 4339. The AMD part has no such scores in the database, so any claim of a win for the AMD processor would have no data behind it. The database shows a clear split: the Intel part is the only one with measurable performance, while the AMD part is documented only through its specifications.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename and belongs to the Ryzen Embedded generation built on Zen 5. Its process node is 4 nm, and the foundry is TSMC. The Intel Core Ultra 5 235T uses the Arrow Lake architecture with the Arrow Lake-S codename and belongs to the Core Ultra Series 2 generation. Its process node is 3 nm, also from TSMC.

The transistor counts differ. The AMD part has 16,630 million transistors across a die size of 2x 70.6 mm², which indicates a chiplet-based design with two compute dies. The Intel part has 17,800 million transistors on a single die of 243 mm². The cache hierarchies are substantially different. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Intel processor has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The AMD part has a much larger total L3 pool, which benefits workloads that repeatedly access large data sets. The Intel part has larger per-core L1 and L2 caches, which can help single-threaded and lightly threaded workloads.

Memory support is another differentiator. Both processors support DDR5 memory and use a dual-channel memory bus. The AMD part has a memory bandwidth of 89.6 GB/s, while the Intel part has a memory bandwidth of 102.4 GB/s. The AMD processor supports ECC memory, while the Intel processor does not. This makes the AMD chip suitable for error-sensitive workloads such as embedded computing and data integrity applications. The Intel chip has no ECC support, so it targets mainstream desktop use.

The PCIe configurations differ as well. The AMD processor provides Gen 5 with 24 lanes from the CPU, while the Intel processor provides Gen 5 with 20 lanes from the CPU. Both support the latest PCIe generation, but the AMD part has more available lanes. The integrated graphics also differ. The AMD processor uses Radeon Graphics, while the Intel processor uses Arc Xe-LPG Graphics 24EU. The sockets are not compatible: the AMD part uses AMD Socket AM5, and the Intel part uses Intel Socket 1851.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, so a direct score-by-score comparison cannot be made. What is available is the full benchmark suite for the Intel Core Ultra 5 235T. The most significant multicore result is the Cinebench R23 multicore score of 26232. The Cinebench R20 multicore score is 11017, and the Cinebench R15 multicore score is 2644. These scores show a consistent scaling pattern across the three Cinebench versions.

Single-core performance for the Intel part is recorded in three Cinebench tests: R15 single-core at 373, R20 single-core at 1555, and R23 single-core at 3703. The PassMark suite adds more detail. The single-thread score is 4339, and the multithread score is 30918. The integer math score is 84244, and the floating point math score is 106546. The extended instructions score is 23212, and the data compression score is 295100. The data encryption score is 23457, and the random string sorting score is 35377. The find prime numbers score is 318, and the physics score is 2157.
