AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 7 265K Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is one-sided. The AMD Ryzen Embedded 9900X3D has no benchmark scores listed in the database, while the Intel Core Ultra 7 265K has a full set of measurements across Cinebench, Geekbench, and Passmark tests. The head-to-head benchmark array is empty, meaning no direct comparative runs were recorded for these two processors.

The Intel Core Ultra 7 265K delivers a Cinebench R23 multi-core score of 35,850 and a single-core score of 2,020. In Cinebench R20, it records 20,918 multi-core and 2,953 single-core. The older R15 test shows 5,020 multi-core and 708 single-core. Geekbench results indicate 23,085 multi-core and 2,713 single-core.

Passmark scores for the 265K are extensive. Multi-thread performance sits at 58,594, single-thread at 4,928. Integer math reaches 143,242, floating-point math 189,629. Data compression scores 665,554, data encryption 48,246, extended instructions 54,333, physics 3,731, and random string sorting 79,752. Prime number finding records 491.

The database shows the 265K holds an average benchmark score of 70,879 and ranks in the 94th percentile among all CPUs. Its nearest rivals are the Intel Xeon 6511P at 71,051 average score (-0.2% delta), the Intel Xeon Platinum 8270 at 71,370 (-0.7%), the Intel Core i7-14700KF at 70,163 (+1%), and the AMD Ryzen 7 9700F at 69,996 (+1.3%). The 265K sits within roughly one percent of these comparable parts, indicating tight competition in this performance tier.

Because the AMD processor lacks any recorded benchmark entries, no win counts can be assigned. The winsA and winsB fields both read zero. The analysis must therefore rely on architectural specifications and the measured performance of the Intel part alone.

Architecture Differences

The AMD Ryzen Embedded 9900X3D belongs to the Ryzen Embedded series within the 9000 series family. Its codename is Granite Ridge, and it uses the Zen 5 (Granite Ridge) generation. The Intel Core Ultra 7 265K comes from the Core Ultra Series 2, with the Arrow Lake architecture and the Arrow Lake-S codename.

Process nodes differ. The AMD part uses a 4 nm node from TSMC, while the Intel part uses a 3 nm node, also from TSMC. Transistor counts are close: 16,630 million for the AMD, 17,800 million for the Intel. Die size differs substantially. The AMD uses a dual-die design at 2x 70.6 mm², totaling roughly 141.2 mm². The Intel uses a single 243 mm² die.

Cache hierarchies are distinct. The AMD processor provides 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The AMD's 128 MB L3 is more than four times the Intel's 30 MB, a significant difference for workloads that benefit from large on-die caches.

Core and thread counts diverge sharply. The AMD has 12 cores and 24 threads, leveraging simultaneous multithreading. The Intel has 20 cores and 20 threads, with no hyperthreading support. This means the Intel part has more physical cores but the AMD part has more logical threads.

Both support DDR5 memory with dual-channel buses. Memory bandwidth differs: the AMD records 89.6 GB/s, the Intel records 102.4 GB/s. Both support ECC memory. PCIe lanes differ, with the AMD offering Gen 5 with 24 lanes (CPU only) and the Intel offering Gen 5 with 20 lanes (CPU only).

Integrated graphics differ. The AMD uses Radeon Graphics, while the Intel uses Arc Xe-LPG Graphics with 64 execution units. Both are unlocked for overclocking per the multiplier unlocked field. Sockets are platform-specific: AMD Socket AM5 for the AMD, Intel Socket 1851 for the Intel.

Where Each One Wins

The Intel Core Ultra 7 265K has measured data across all major benchmark suites, so its strengths are directly quantifiable. Its 94th percentile ranking among all CPUs indicates strong overall performance. The Cinebench R23 multi-core score of 35,850 demonstrates heavy multi-threaded capability, while the single-core score of 2,020 shows competitive lightly-threaded performance. Geekbench multi-core at 23,085 and single-core at 2,713 reinforce this pattern.

Passmark results for the 265K show particular strength in data compression (665,554) and floating-point math (189,629). Integer math at 143,242 and random string sorting at 79,752 are also notable. The physics score of 3,731 and extended instructions score of 54,333 round out the picture. The 265K's nearest rivals all fall within a narrow band around its average score, with the two Xeon parts slightly ahead and the Core i7-14700KF and Ryzen 7 9700F slightly behind.

The AMD Ryzen Embedded 9900X3D has no recorded benchmark scores, so its wins cannot be measured from the data. However, architectural specifications suggest where it could excel. The 128 MB L3 cache is unusually large and, combined with the Zen 5 architecture, could benefit cache-sensitive workloads such as database operations, scientific simulations, or certain rendering tasks. The 24 threads from 12 cores with SMT could help in heavily parallel workloads where thread count matters more than raw core count.

The AMD part also carries a lower TDP of 120 watts compared to the Intel's 125 watts. The AMD has more PCIe lanes (24 vs. 20), which could matter for systems with many expansion devices. The AMD's dual-die design with 2x 70.6 mm² dies may offer thermal advantages due to smaller individual dies, though the database does not provide thermal measurements to confirm this.

The Verdict

The Intel Core Ultra 7 265K is the only processor in this comparison with recorded benchmark data. Its 94th percentile ranking, average benchmark score of 70,879, and strong results across Cinebench, Geekbench, and Passmark make it a proven performer. The data shows it sits within one percent of its nearest rivals, including the Intel Xeon 6511P, Xeon Platinum 8270, Core i7-14700KF, and AMD Ryzen 7 9700F. The 20 cores, 102.4 GB/s memory bandwidth, and 30 MB of shared L3 cache support its measured output.

The AMD Ryzen Embedded 9900X3D presents a different profile based on specifications alone. Its 128 MB L3 cache, 24 threads, and 120 W TDP indicate a design aimed at cache-heavy and thread-scalable workloads. The 4.40 GHz base clock is higher than the Intel's 3.90 GHz, and both reach 5.50 GHz boost. The AMD part also offers more PCIe lanes at 24 versus 20.

For users choosing between these two, the Intel part has the advantage of verified benchmark results and a 94th percentile standing. The AMD part offers architectural features that could be beneficial in specific scenarios, particularly those that exploit large L3 caches or need more threads than cores. The database records no benchmark scores for the AMD part, so its actual performance cannot be compared numerically. The Intel Core Ultra 7 265K, with its measured performance and established position among rivals, is the better-documented choice. The AMD Ryzen Embedded 9900X3D remains an option for systems where its specific architectural characteristics, such as the 128 MB L3 cache and 24 PCIe lanes, are prioritized over demonstrated benchmark results.
