Architecture Differences

The two processors present fundamentally different design philosophies. The AMD Ryzen Embedded 9900X uses the Granite Ridge architecture based on Zen 5, built on a 4 nm process at TSMC. It uses a chiplet design with a die size of 2x 70.6 mm², totaling 16,630 million transistors. The Intel Core Ultra 5 245K uses the Arrow Lake architecture (Arrow Lake-S), built on a 3 nm process at TSMC, with a monolithic die size of 243 mm² and 17,800 million transistors.

The cache hierarchy differs significantly. The AMD processor allocates 80 KB of L1 cache per core and 1 MB of L2 cache per core, with a large 64 MB shared L3 cache. The Intel chip provides 192 KB of L1 cache per core and 3 MB of L2 cache per core, but only 24 MB of shared L3 cache. This means the AMD chip has over 2.5 times the total L3 capacity, which can be advantageous for workloads that repeatedly access large datasets.

Threading is another major divergence. The AMD Ryzen Embedded 9900X supports simultaneous multithreading, delivering 24 threads from 12 cores. The Intel Core Ultra 5 245K does not support hyper-threading, so it offers 14 threads from 14 cores. This gives the AMD part a 10-thread advantage in heavily threaded scenarios.

PCIe connectivity also differs. The AMD processor provides Gen 5 with 24 lanes (CPU only), while the Intel chip provides Gen 5 with 20 lanes (CPU only). Both support DDR5 dual-channel memory, but the Intel part has a higher memory bandwidth rating at 102.4 GB/s versus 89.6 GB/s for AMD. Integrated graphics differ as well: AMD includes Radeon Graphics, while Intel includes Arc Xe-LPG Graphics with 64 execution units.

The Intel processor was released on 2024-10-23, while the AMD processor launched later on 2025-10-06. Both processors are active production parts with unlocked multipliers. The Intel chip has a launch MSRP of $319, while no launch MSRP is recorded for the AMD part.

Head-to-Head Benchmarks

The database contains benchmark results only for the Intel Core Ultra 5 245K, with no recorded scores for the AMD Ryzen Embedded 9900X. Therefore, the comparison relies on the Intel chip's absolute performance and its position relative to nearby rivals.

The Intel Core Ultra 5 245K posts a strong multi-core result in Cinebench R23, scoring 25,066. Its single-core score in the same test is 2,132. In Cinebench R20, it scores 15,368 multi-core and 2,169 single-core. In the older Cinebench R15, it scores 3,850 multi-core and 322 single-core.

PassMark results further characterize the Intel chip. Its multi-thread score is 43,047, and its single-thread score is 4,714. In specialized workloads, the chip scores 458,817 in data compression, 33,286 in data encryption, 37,617 in extended instructions, 414 in find prime numbers, 130,678 in floating point math, 98,524 in integer math, 3,081 in physics, and 55,098 in random string sorting.

The Intel Core Ultra 5 245K achieves a percentile of 91 among all CPUs in the database, with an average benchmark score of 54,053. Its nearest rivals show tight competition. The Intel Xeon 6505P scores 53,701, placing the Ultra 5 245K 0.7% ahead. The Intel Core i7-14700F scores 53,620, putting the Ultra 5 245K 0.8% ahead. The Intel Xeon Phi 7290 scores 53,469, with the Ultra 5 245K 1.1% ahead. The AMD Ryzen 9 9900X3D scores 54,762, which is 1.3% ahead of the Ultra 5 245K.

Across the recorded benchmarks, the Intel chip demonstrates consistent strength in both single-threaded and multi-threaded tasks. Its Cinebench R23 multi-core score of 25,066 indicates solid all-core throughput, while the single-core score of 2,132 shows competent per-thread performance. The PassMark integer math score of 98,524 and floating-point score of 130,678 suggest balanced arithmetic capability.

The Verdict

For users who rely on the recorded benchmark data, the Intel Core Ultra 5 245K is the only processor with verified performance scores in the database. It sits in the 91st percentile of all CPUs, which indicates strong overall performance. Its average benchmark score of 54,053 places it slightly behind the AMD Ryzen 9 9900X3D, which leads by 1.3%, but ahead of several Intel Xeon and Core i7 parts by margins of 0.7% to 1.1%.

The AMD Ryzen Embedded 9900X has no recorded benchmark scores in the database, so its performance cannot be quantified here. However, its architecture suggests advantages in specific scenarios. The 24-thread count from 12 cores with SMT provides more thread-level parallelism than the Intel chip's 14 threads. The 64 MB L3 cache is substantially larger than Intel's 24 MB, which may benefit workloads with large working sets.

The Intel Core Ultra 5 245K offers higher memory bandwidth (102.4 GB/s versus 89.6 GB/s) and a more recent 3 nm process node. It also has a recorded launch MSRP of $319. The AMD chip does not have a recorded launch MSRP in the database.

Users who prioritize verified benchmark performance and a known price point would select the Intel Core Ultra 5 245K. Users who need maximum thread count and large L3 cache, and who are willing to wait for benchmark data on the AMD part, would consider the Ryzen Embedded 9900X.

Where Each One Wins

Based on the recorded data, the Intel Core Ultra 5 245K wins in all categories that have benchmark results. Its multi-thread score of 43,047 in PassMark and 25,066 in Cinebench R23 demonstrate strong all-core performance. Its single-thread score of 4,714 in PassMark and 2,132 in Cinebench R23 show capable per-core performance. The chip also delivers high scores in specific tasks: 458,817 in data compression, 130,678 in floating-point math, and 98,524 in integer math.

The Intel chip wins on memory bandwidth, offering 102.4 GB/s compared to AMD's 89.6 GB/s. It also has a more recent process node at 3 nm versus 4 nm. Its integrated graphics, Arc Xe-LPG with 64 execution units, may provide better graphics capability than AMD's Radeon Graphics, though no benchmark data confirms this.

The AMD Ryzen Embedded 9900X wins on thread count, providing 24 threads versus Intel's 14 threads. This gives it a theoretical advantage in heavily parallel workloads such as video rendering, scientific simulation, and server-side processing. Its 64 MB L3 cache is 2.67 times larger than Intel's 24 MB, which can reduce memory latency for cache-resident workloads. The AMD chip also provides more PCIe lanes (24 versus 20), which supports more expansion devices or storage drives.

The AMD part has a higher boost clock at 5.60 GHz versus 5.20 GHz for Intel, which may translate to better single-thread performance, though no benchmark confirms this. Both processors support ECC memory and have unlocked multipliers, so overclocking potential exists on both sides.

The database does not contain benchmark scores for the AMD Ryzen Embedded 9900X, so its real-world performance remains unverified. The Intel Core Ultra 5 245K, by contrast, has a complete set of scores placing it at the 91st percentile of all CPUs. Users requiring immediate, verified performance data should choose the Intel part. Users prioritizing thread count, L3 cache size, and PCIe lane count, and who can wait for benchmark validation, would evaluate the AMD part based on those architectural advantages.
