AMD Ryzen Embedded 9900X vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The recorded database contains a full benchmark suite for the Intel Core 9 273PE, while the AMD Ryzen Embedded 9900X has no benchmark entries in this dataset. As a result, the head-to-head comparison is one-sided: every measurable performance figure belongs to the Intel part. The Intel Core 9 273PE posts a Cinebench R23 multi-core score of 31,288 and a single-core score of 4,417. In Cinebench R20, it records 13,140 multi-core and 1,855 single-core. The older Cinebench R15 run shows 3,153 multi-core and 445 single-core.

PassMark results for the Intel chip are extensive. The multi-thread score reaches 36,810, while the single-thread score sits at 3,650. Integer math completes at 139,410, floating point math at 107,884, and extended instructions at 24,630. Data compression scores 405,885, while data encryption achieves 22,719. Prime number finding returns 203, physics processing hits 3,120, and random string sorting ends at 45,098.

The AMD Ryzen Embedded 9900X has zero recorded benchmark scores in this database, which means no direct win comparisons can be drawn. The Intel chip holds all recorded wins by default of data availability. Its average benchmark score is 49,845, placing it at the 90th percentile among all CPUs in the database. The AMD unit sits at the 50th percentile with an average benchmark score of zero, reflecting the absence of test data rather than a performance verdict.

The nearest rivals for the Intel Core 9 273PE provide context for its standing. The AMD Ryzen AI Max+ 388 scores 49,796, a delta of 0.1% above the Intel part, making them statistically tied. The Intel Core i5-14600KF scores 49,394, which is 0.9% lower. The Intel Core i9-13980HX scores 50,398, putting it 1.1% ahead of the 273PE. The AMD Ryzen AI 9 HX PRO 370 scores 50,448, which is 1.2% ahead. These deltas show the 273PE clustering tightly with comparable desktop and mobile parts, neither dominating nor being dominated by any single rival.

Architecture Differences

The two processors diverge sharply on manufacturing process. The AMD Ryzen Embedded 9900X uses a 4 nm process from TSMC, while the Intel Core 9 273PE uses a 10 nm process from Intel. The AMD chip integrates 16,630 million transistors across a die composed of two 70.6 mm² chiplets. The Intel part has no transistor count or die size recorded in the database.

Both CPUs share a 12-core, 24-thread configuration. The AMD part has a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The Intel part runs a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The AMD chip carries a 120 W TDP, while the Intel chip is rated at 65 W. The AMD processor has an unlocked multiplier; the Intel processor does not.

Cache layouts differ considerably. Both use 80 KB of L1 cache per core. The AMD part has 1 MB of L2 per core, while the Intel part has 2 MB of L2 per core. The L3 cache is far larger on the AMD side at 64 MB, versus 36 MB shared on the Intel side. No 3D V-Cache is present on either chip.

Memory support also separates them. The AMD part supports DDR5 only, with a dual-channel bus and 89.6 GB/s of bandwidth. The Intel part supports both DDR4 and DDR5, also dual-channel, with the same 89.6 GB/s bandwidth figure. Both support ECC memory.

PCIe connectivity differs: the AMD chip provides 24 PCIe Gen 5 lanes from the CPU, while the Intel chip provides 16 PCIe Gen 5 lanes. Integrated graphics are present on both, with AMD using Radeon Graphics and Intel using UHD Graphics 730.

The sockets are incompatible. The AMD part uses AMD Socket AM5, and the Intel part uses Intel Socket 1700. The AMD codename is Granite Ridge, part of the Ryzen Embedded series based on Zen 5. The Intel codename is Bartlett Lake, part of the Core 9 generation. The AMD release date is 2025-10-06, while the Intel release date is 2026-03-08. The Intel part has a launch MSRP of $549; no launch MSRP is recorded for the AMD part.

The Verdict

From the recorded data alone, the Intel Core 9 273PE is the only chip with benchmark results, so any selection between them rests entirely on its measured performance and the AMD chip's lack of measurements. The Intel part achieves a 90th percentile standing among all CPUs in the database, with an average benchmark score of 49,845. Its nearest rivals are all within a 1.2% delta, indicating strong competition from both AMD and Intel parts in adjacent segments.

The AMD Ryzen Embedded 9900X offers architectural advantages on paper: a smaller 4 nm process, a larger 64 MB L3 cache, a higher base clock of 4.40 GHz, an unlocked multiplier, and 24 PCIe Gen 5 lanes. It also draws a higher 120 W TDP, which suggests higher power delivery capacity, but no power or thermal measurements exist in the database to confirm performance implications.

The Intel part counters with a higher boost clock of 5.70 GHz, a lower 65 W TDP, dual memory support for DDR4 and DDR5, and a larger L2 cache per core at 2 MB. Its recorded Cinebench R23 multi-core score of 31,288 and PassMark multi-thread score of 36,810 establish a concrete performance baseline. The AMD chip has no such baseline in this database.

For a buyer choosing strictly on measured results, only the Intel part has evidence of performance. For a buyer weighing architecture specifications without test data, the AMD part shows a more advanced process node and larger L3 pool, but those attributes cannot be converted into performance numbers here. The verdict from the data: the Intel Core 9 273PE is the only option with verified benchmark output, while the AMD Ryzen Embedded 9900X remains unquantified in the database.

Where Each One Wins

The Intel Core 9 273PE wins in every category where a benchmark score exists. Its Cinebench R23 multi-core score of 31,288 and single-core score of 4,417 demonstrate strong rendering and single-threaded application performance. The PassMark integer math score of 139,410 and floating point math score of 107,884 indicate solid computational throughput for general and scientific workloads. Data compression at 405,885 and encryption at 22,719 cover storage and security-related tasks. Physics at 3,120 and random string sorting at 45,098 round out the measured workload coverage.

The AMD Ryzen Embedded 9900X wins in no measured category because the database contains no test results for it. However, on specifications alone, it leads in L3 cache capacity at 64 MB versus 36 MB, in PCIe lane count at 24 versus 16, in process node at 4 nm versus 10 nm, and in base clock at 4.40 GHz versus 2.30 GHz. Its unlocked multiplier also allows user-controlled frequency adjustment, a feature the Intel part lacks. These specification advantages cannot be validated with performance data from this dataset.

The Intel part also wins on power efficiency as recorded, with a 65 W TDP against the AMD chip's 120 W TDP, though no thermal or power consumption measurements exist to confirm real-world behavior. The Intel chip supports both DDR4 and DDR5 memory, giving it broader memory compatibility, while the AMD chip is restricted to DDR5. The Intel part has a recorded launch MSRP of $549, but no price comparison is possible since the AMD chip has no launch MSRP in the database.

For specific use cases, the Intel Core 9 273PE shows recorded strength in multi-threaded rendering, single-thread responsiveness, and data processing tasks based on its benchmark suite. The AMD Ryzen Embedded 9900X presents a larger cache pool and more PCIe connectivity, which could benefit workloads that rely heavily on cache residency or high-bandwidth peripheral expansion, but no measured data supports that claim. In the absence of AMD benchmarks, the Intel part stands as the only chip with verified performance coverage across all tested workloads.
