AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 5 245KF Comparison

Where Each One Wins

The Intel Core Ultra 5 245KF holds the clear advantage in measured performance across the board. The database records 17 individual benchmark scores for the Intel part, while the AMD Ryzen Embedded 9900X3D has no recorded benchmark entries. This means every available performance comparison in the database favors the Intel processor, as it is the only one of the two with validated test results.

The Intel Core Ultra 5 245KF delivers its strongest results in multi-threaded workloads. Its Cinebench R23 multi-core score of 36,647 points and Cinebench R20 multi-core score of 15,391 points indicate substantial parallel processing capability. The PassMark multithread score of 43,110 further confirms this strength. Single-thread performance is also solid, with a Cinebench R23 single-core score of 5,173 and a PassMark single-thread score of 4,715.

The AMD Ryzen Embedded 9900X3D, despite lacking recorded benchmarks, presents a different theoretical positioning. Its 12 cores and 24 threads provide simultaneous multithreading, which the Intel part lacks with its 14 cores and 14 threads. The AMD processor carries 128 MB of L3 cache, which is significantly larger than the Intel processor's 24 MB shared L3 cache. This cache configuration is designed for workloads that benefit from large data residency, though no benchmark data in the database confirms this advantage.

The Intel part's 91st percentile ranking among all CPUs in the database places it well above the AMD part's 50th percentile. The Intel processor also records an average benchmark score of 55,093, while the AMD processor shows a score of zero due to absent test data. For workloads like data compression, encryption, extended instruction execution, prime number calculation, floating-point math, integer math, physics simulation, and random string sorting, the Intel processor has measured results that the AMD processor cannot match in the current database.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 9900X3D uses the Granite Ridge codename with Zen 5 architecture, manufactured on a 4 nm process by TSMC. The Intel Core Ultra 5 245KF uses the Arrow Lake-S codename with Arrow Lake architecture, also manufactured by TSMC but on a 3 nm process.

The AMD processor integrates 16,630 million transistors across a dual-die configuration with two 70.6 mm² dies. The Intel processor contains 17,800 million transistors on a single 243 mm² die. This represents a difference in physical layout and manufacturing approach, with AMD opting for a chiplet strategy and Intel using a monolithic die.

Cache hierarchies differ substantially. The AMD part provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel part provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The AMD processor's total cache footprint is far larger, particularly at the L3 level. The Intel processor's per-core L1 and L2 allocations are larger, which can benefit latency-sensitive single-thread operations.

Memory support also differs. Both processors support DDR5 memory with dual-channel buses, but the Intel part achieves a higher memory bandwidth of 102.4 GB/s compared to the AMD part's 89.6 GB/s. The AMD processor supports ECC memory, while the Intel processor does not. This makes the AMD part more suitable for error-correcting workloads in embedded or server-like environments.

PCIe connectivity varies between the two. 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. The AMD part includes integrated Radeon Graphics, whereas the Intel part has no integrated graphics. The Intel processor carries an unlocked multiplier, and so does the AMD processor, allowing overclocking on both platforms.

The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel Socket 1851. The AMD part belongs to the Ryzen Embedded 9000 series with a release date of October 6, 2025. The Intel part belongs to the Core Ultra Series 2 with a release date of October 23, 2024. Both are classified as active production parts in the desktop market segment.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Ryzen Embedded 9900X3D and the Intel Core Ultra 5 245KF. All recorded benchmark data belongs exclusively to the Intel processor. The wins counter shows zero for the AMD part and zero for the Intel part in direct comparisons, reflecting the absence of paired test results.

However, the Intel processor's standalone benchmark scores provide a reference point. In Cinebench R15, the Intel part scores 3,693 in multi-core and 521 in single-core. In Cinebench R20, the scores are 15,391 multi-core and 2,172 single-core. In Cinebench R23, the scores are 36,647 multi-core and 5,173 single-core. These results demonstrate consistent scaling across the Cinebench versions.

The PassMark suite offers additional granularity. Data compression scores 460,123, data encryption scores 33,381, and extended instructions score 37,912. Prime number finding scores 416, floating-point math scores 131,546, and integer math scores 98,854. Multithread performance scores 43,110, physics scores 2,998, and random string sorting scores 55,206. The single-thread PassMark score is 4,715, which appears twice in the database under slightly different test names.

Relative to its nearest rivals in the database, the Intel Core Ultra 5 245KF shows tight competition. It sits 0.6% ahead of the AMD Ryzen 9 9900X3D, which has an average score of 54,762. It trails the Intel Core 7 253PQE by 1.5%, that part scoring 55,919. It trails the Intel Core i9-14900HX by 1.6%, that part scoring 56,004. It sits 1.9% ahead of the Intel Core Ultra 5 245K, which scores 54,053. These small percentage differences indicate that the Intel Core Ultra 5 245KF performs within a narrow band of its closest competitors.

The AMD Ryzen Embedded 9900X3D has no nearest rivals listed and no average benchmark score, so no comparative analysis can be drawn from the database for this part. The Intel processor's 91st percentile versus all CPUs in the database stands in contrast to the AMD processor's 50th percentile, though the latter figure reflects a lack of measured data rather than a confirmed performance level.

Specification Differences

The two processors differ across several key specification fields. Core and thread counts are the most obvious divergence: the AMD part has 12 cores and 24 threads, while the Intel part has 14 cores and 14 threads. The AMD processor enables simultaneous multithreading, giving each core two threads. The Intel processor does not, so its thread count equals its core count.

Clock speeds differ as well. The AMD processor has a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The Intel processor has a base clock of 4.20 GHz and a boost clock of 5.20 GHz. The AMD part runs higher at both ends, though the Intel part's lower clocks are paired with its higher memory bandwidth.

Thermal design power differs slightly. The AMD processor has a TDP of 120 watts, while the Intel processor has a TDP of 125 watts. Both are within a similar power envelope, with the Intel part drawing marginally more.

Process node and die configuration present clear differences. The AMD part uses a 4 nm process, while the Intel part uses a 3 nm process. The AMD part has a dual-die design with two 70.6 mm² dies, while the Intel part uses a single 243 mm² die. Transistor counts are close: 16,630 million for AMD and 17,800 million for Intel.

Cache sizes differ across all levels. The AMD part has 80 KB L1 per core, 1 MB L2 per core, and 128 MB L3. The Intel part has 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. The total cache capacity favors AMD heavily at L3, while Intel provides more per-core L1 and L2.

Memory bandwidth shows Intel ahead at 102.4 GB/s versus AMD's 89.6 GB/s. ECC memory support is present on the AMD part and absent on the Intel part. PCIe lanes favor AMD with 24 lanes versus Intel's 20 lanes, both at Gen 5. Integrated graphics are present on the AMD part as Radeon Graphics, while the Intel part has none.

Sockets and release dates differ. The AMD part uses AMD Socket AM5 and released on October 6, 2025. The Intel part uses Intel Socket 1851 and released on October 23, 2024. The Intel part has a recorded launch MSRP of $294, while the AMD part has no launch MSRP listed. Both parts have unlocked multipliers and are in active production.
