AMD Ryzen Embedded 9900X vs Intel Core Ultra 7 265K Comparison

The Verdict

The data in this comparison is one-sided. The Intel Core Ultra 7 265K holds every recorded benchmark score in the database, while the AMD Ryzen Embedded 9900X has no benchmark entries at all. The Intel processor sits at the 94th percentile among all CPUs, with an average benchmark score of 70,879. The AMD part is at the 50th percentile with an average score of zero, reflecting the absence of measured results. For anyone selecting a desktop processor on measured performance alone, the Intel Core Ultra 7 265K is the only option with data to support it.

The AMD Ryzen Embedded 9900X is an active production part aimed at the desktop segment, but the lack of benchmark data means its actual performance cannot be verified from this database. The Intel Core Ultra 7 265K, by contrast, has a full suite of Cinebench, Geekbench, and PassMark results. The choice, strictly from the recorded data, is clear: the Intel part delivers measurable performance, while the AMD part delivers specifications only. Buyers who need verified numbers should pick the Intel Core Ultra 7 265K. Buyers who require an embedded AMD processor with AM5 socket compatibility and Radeon integrated graphics would choose the Ryzen Embedded 9900X based purely on its feature set, not on any measured score.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename and is built on the Zen 5 architecture. It has 12 cores and 24 threads, which means simultaneous multithreading is enabled. The process node is 4 nm, fabricated by TSMC. The Intel Core Ultra 7 265K uses the Arrow Lake-S codename and the Arrow Lake architecture, built on a 3 nm TSMC process. It has 20 cores but only 20 threads, so it does not use hyper-threading; each core corresponds to exactly one thread.

The transistor counts are close. The AMD chip has 16,630 million transistors across a die size of 2x 70.6 mm². The Intel chip has 17,800 million transistors on a single 243 mm² die. The cache layouts differ substantially. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. Intel provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. AMD's larger L3 cache (64 MB versus 30 MB) is the main cache advantage, while Intel has more L1 and L2 per core.

Both support DDR5 memory over a dual-channel bus. The memory bandwidth figures differ: AMD lists 89.6 GB/s, Intel lists 102.4 GB/s. Both support ECC memory. Both use PCIe Gen 5, but AMD offers 24 lanes (CPU only) while Intel offers 20 lanes (CPU only). Both have integrated graphics: AMD uses Radeon Graphics, Intel uses Arc Xe-LPG Graphics with 64 execution units. Both have unlocked multipliers, and both are active production parts.

Head-to-Head Benchmarks

The head-to-head benchmark array in the database is empty, and the wins counters show zero for both processors. However, the Intel Core Ultra 7 265K has a complete set of individual benchmark scores recorded. The AMD Ryzen Embedded 9900X has no scores in any test. This creates an implicit comparison: the Intel part wins every category by default because the AMD part has no recorded results.

Looking at the Intel numbers in isolation, the multi-core performance is strong. Cinebench R15 multicore scores 5,020, Cinebench R20 multicore scores 20,918, and Cinebench R23 multicore scores 35,850. Geekbench multicore reaches 23,085. PassMark multithread scores 58,594, with integer math at 143,242 and floating-point math at 189,629. The single-core results are also solid: Cinebench R15 singlecore scores 708, Cinebench R20 singlecore scores 2,953, Cinebench R23 singlecore scores 2,020, and Geekbench singlecore scores 2,713. PassMark single-thread scores 4,928.

Specialized workloads show Intel's capabilities. PassMark data compression scores 665,554, data encryption scores 48,246, and extended instructions score 54,333. Random string sorting scores 79,752, and physics scores 3,731. Prime number finding is the lowest score at 491, which is typical for that workload. The nearest rivals in the database put these numbers in context. The Intel Xeon 6511P scores 71,051, just 0.2% above the Core Ultra 7 265K. The Intel Xeon Platinum 8270 scores 71,370, 0.7% above. The Intel Core i7-14700KF scores 70,163, 1% below. The AMD Ryzen 7 9700F scores 69,996, 1.3% below. The Core Ultra 7 265K sits within a narrow band of high-end desktop and server parts, effectively matching the Xeon 6511P and edging out the i7-14700KF and Ryzen 7 9700F.

Where Each One Wins

The Intel Core Ultra 7 265K wins every measured category because the AMD Ryzen Embedded 9900X has no recorded benchmark data. In multi-core workloads, the Intel part demonstrates strong throughput with a Cinebench R23 multicore score of 35,850 and a PassMark multithread score of 58,594. In single-core tasks, the Cinebench R23 singlecore score of 2,020 and Geekbench singlecore score of 2,713 indicate solid per-thread performance. In specialized workloads, the PassMark data compression score of 665,554 and extended instructions score of 54,333 show strength in data-heavy and instruction-intensive applications. The Intel part also carries a 94th percentile ranking, placing it above the vast majority of CPUs in the database.

The AMD Ryzen Embedded 9900X wins on specification-driven attributes. It offers more PCIe lanes (24 versus 20) for CPU-only connectivity, which can matter for expansion-heavy systems. Its 64 MB L3 cache is double the Intel part's 30 MB, which can benefit cache-sensitive workloads. It has a higher base clock at 4.40 GHz versus 3.90 GHz and a higher boost clock at 5.60 GHz versus 5.50 GHz. It also uses a smaller dual-die layout at 2x 70.6 mm², which may suit certain embedded form factors. However, none of these advantages are backed by measured performance in the database, so they remain theoretical.
