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

The Verdict

The data in this comparison is one-sided because the AMD Ryzen Embedded 9900X3D has no recorded benchmark scores in the database. The Intel Core Ultra 7 265KF carries the full set of measurements, with a 94th percentile ranking among all CPUs and an average benchmark score of 71,910. The AMD part sits at the 50th percentile with an average score of 0, which reflects the absence of test data rather than a true performance result. For any workload where measured performance matters, the Intel Core Ultra 7 265KF is the only option with verified data. The Ryzen Embedded 9900X3D offers architectural advantages on paper, such as 128 MB of L3 cache and 24 threads, but without benchmark results there is no numerical basis to award it a win in any tested workload. The Intel chip’s nearest rivals, the AMD Ryzen 7 8840HX at 71,797 (0.2% lower), the Intel Xeon Platinum 8270 at 71,370 (0.8% lower), and the Intel Xeon 6517P at 72,350 (0.6% higher), all sit within 1% of its average score, indicating the 265KF is tightly grouped with high-end server and workstation processors.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X3D belongs to the 9000 series, uses the Granite Ridge codename, and is built on Zen 5 architecture at a 4 nm process node from TSMC. It integrates 12 cores and 24 threads, with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The cache hierarchy is distinctive: 80 KB of L1 per core, 1 MB of L2 per core, and a large 128 MB L3 cache. The chip uses AMD Socket AM5, supports DDR5 memory over a dual-channel bus with 89.6 GB/s of bandwidth, and includes ECC memory support. It also carries Radeon Graphics as integrated graphics, which the Intel part lacks entirely.

The Intel Core Ultra 7 265KF is part of Core Ultra Series 2, uses the Arrow Lake codename, and is built on 3 nm process technology, also from TSMC. It provides 20 cores and 20 threads, with a base clock of 3.90 GHz and a boost clock of 5.50 GHz. Its cache layout differs significantly: 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The chip uses Intel Socket 1851, supports DDR5 over a dual-channel bus with higher memory bandwidth at 102.4 GB/s, but does not support ECC memory. Its transistor count is 17,800 million across a 243 mm² die, while the AMD chip uses 16,630 million transistors across a dual-die design of 2x 70.6 mm². Both processors have unlocked multipliers, but the Intel part is the only one with a documented launch MSRP of $379.

The thread count difference matters for scheduling. The AMD chip offers 24 threads from 12 cores, while the Intel chip has 20 threads from 20 cores. That means the AMD part relies on simultaneous multithreading, whereas the Intel part uses only physical cores. The AMD part’s 128 MB L3 cache is more than four times the Intel part’s 30 MB, which can benefit cache-sensitive workloads, though no benchmark data confirms this advantage.

Head-to-Head Benchmarks

There are no head-to-head benchmark results in the database for these two processors. The AMD Ryzen Embedded 9900X3D has an empty benchmarks array, so the comparison cannot be made on equal terms. The Intel Core Ultra 7 265KF, however, has a complete set of measurements across Cinebench, Geekbench, and Passmark tests.

The Intel chip’s Cinebench scores establish a strong baseline. It records 5,013 in Cinebench R15 multi-core and 707 in single-core. In Cinebench R20, it reaches 20,889 multi-core and 2,948 single-core. Cinebench R23 shows 49,736 multi-core and 7,021 single-core. These results place it in the 94th percentile of all CPUs, with an average benchmark score of 71,910.

Geekbench results for the Intel part show 22,913 multi-core and 2,759 single-core. Passmark results cover a broader range of workloads. Multi-thread performance is 58,518, single-thread performance is 4,928, integer math is 143,351, floating point math is 189,431, extended instructions reach 54,513, data compression is 666,589, data encryption is 48,198, physics is 3,633, random string sorting is 79,735, and find prime numbers is 486.

Without any recorded scores for the AMD processor, every one of these metrics is a win for the Intel chip by default. The AMD part’s percentile ranking of 50 and average benchmark score of 0 reinforce that no measured data exists to compare against. The nearest rival data for the Intel chip shows how competitive it is against other processors. The AMD Ryzen 7 8840HX scores 71,797, which is 0.2% lower. The Intel Xeon 6517P scores 72,350, which is 0.6% higher. The Intel Xeon 6724P scores 72,396, which is 0.7% higher. The Intel Xeon Platinum 8270 scores 71,370, which is 0.8% lower. The 265KF effectively trades places with these parts within a narrow band of roughly 1.5% total spread.

Where Each One Wins

The Intel Core Ultra 7 265KF wins in every measured category because it is the only processor with benchmark data. Its Cinebench R23 multi-core score of 49,736 and single-core score of 7,021 show strong rendering performance. Geekbench results of 22,913 multi-core and 2,759 single-core confirm general compute capability. Passmark results cover specialized workloads: floating point math at 189,431, integer math at 143,351, extended instructions at 54,513, data compression at 666,589, data encryption at 48,198, and random string sorting at 79,735. The 94th percentile ranking places it among the top processors in the database.

The AMD Ryzen Embedded 9900X3D has no recorded wins. Its 128 MB L3 cache and 24 threads are notable on paper, but the database contains no measurements to substantiate any performance advantage. The 50th percentile ranking reflects the absence of data, not a measured competitive position. The AMD part does have qualitative advantages that are not benchmarked: ECC memory support, integrated Radeon Graphics, and a lower TDP of 120 W versus 125 W. It also offers 24 PCIe Gen 5 lanes compared to 20 on the Intel chip. These are specification-level differences, not measured performance differences.

For users who rely on verified benchmark results, the Intel Core Ultra 7 265KF is the only choice with data backing it. The AMD part remains an unmeasured option whose architectural traits, such as the large L3 cache and SMT-enabled thread count, cannot be quantified against the Intel chip from the recorded information. The nearest rival comparisons for the Intel chip show it competing within 1% of several Xeon and Ryzen parts, which suggests its measured performance is consistent with high-end server and workstation processors.
