AMD Ryzen Embedded 9900X vs Intel Core Ultra 5 245 Comparison

Where Each One Wins

The benchmark data splits these two desktop processors into distinct roles. The AMD Ryzen Embedded 9900X has no recorded benchmark scores in the database, so all measured performance results belong to the Intel Core Ultra 5 245. That asymmetry defines the comparison: the Intel part carries every available data point, while the AMD part is defined by its specifications alone.

The Intel Core Ultra 5 245 sits at the 90th percentile of all CPUs in the database, with an average benchmark score of 48,995. Its nearest rivals bracket it closely: the AMD Ryzen 7 PRO 5755G scores 49,196 (0.4% higher), the AMD Ryzen 9 7900 scores 49,228 (0.5% higher), the Intel Xeon Gold 5318H scores 48,698 (0.6% lower), and the Intel Core i5-14600K scores 48,618 (0.8% lower). This places the Core Ultra 5 245 in a tight cluster where single-digit percentage differences separate it from four comparable processors.

The AMD Ryzen Embedded 9900X shows no wins in the head-to-head table because no head-to-head benchmarks exist. The Intel Core Ultra 5 245 likewise shows zero recorded wins, but it has a full set of 17 benchmark scores across Cinebench and Passmark tests. The use-case split therefore comes from what the Intel measurements reveal about its strengths, and what the AMD specifications imply for workloads that depend on core count, cache size, and memory bandwidth.

Architecture Differences

The two processors take fundamentally different design paths. The AMD Ryzen Embedded 9900X uses the Granite Ridge architecture from the Zen 5 generation, built on TSMC's 4 nm process. It packs 12 cores and 24 threads, with a base clock of 4.40 GHz and a boost clock of 5.60 GHz. The chip contains 16,630 million transistors across two 70.6 mm² dies. Its cache layout gives each core 80 KB of L1, 1 MB of L2, and a shared 64 MB L3 pool. Memory support is DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth, and ECC memory is supported. The CPU provides 24 Gen 5 PCIe lanes and includes Radeon Graphics as integrated graphics. It runs on AMD Socket AM5 with a 120 W TDP, and the multiplier is unlocked.

The Intel Core Ultra 5 245 uses the Arrow Lake-S architecture from the Core Ultra Series 2, built on TSMC's 3 nm process. It has 14 cores but only 14 threads, meaning no hyperthreading, with a base clock of 3.50 GHz and a boost clock of 5.10 GHz. The die contains 17,800 million transistors on a single 243 mm² die. Each core gets 192 KB of L1 and 3 MB of L2, with a shared 24 MB L3. Memory support is DDR5 on a dual-channel bus with 102.4 GB/s of bandwidth, and ECC memory is supported. The CPU provides 20 Gen 5 PCIe lanes and includes Arc Xe-LPG Graphics with 64 execution units. It runs on Intel Socket 1851 with a 65 W TDP, and the multiplier is locked.

The process node difference is small but real: 3 nm versus 4 nm. The Intel chip uses fewer transistors per core but more total transistors, and its single die is much larger at 243 mm² versus the AMD dual-die setup at 70.6 mm² each. The AMD part has a significantly larger L3 cache at 64 MB versus 24 MB, which matters for workloads that repeatedly access large datasets. The Intel part has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s, which favors memory-bound tasks.

Head-to-Head Benchmarks

Because the AMD Ryzen Embedded 9900X has no recorded benchmark scores, the head-to-head section relies entirely on the Intel Core Ultra 5 245's measurements. The Cinebench results show a multicore score of 3,318 in R15, 13,828 in R20, and 32,924 in R23. Single-core scores are 468 in R15, 1,952 in R20, and 4,648 in R23. These figures indicate strong scaling from R15 through R23, with the multicore score growing by roughly 10x from the R15 baseline to the R23 result.

The Passmark suite adds detail. Data compression scores 400,942, which is the single highest result in the entire set. Data encryption scores 30,236, extended instructions score 33,304, and finding prime numbers scores 365. Floating point math scores 120,548, integer math scores 91,187, and multithread scores 38,706. Physics scores 2,569, random string sorting scores 49,140, and single-thread performance scores 4,394 in both the single_thread and singlethread entries.

The multithread score of 38,706 versus the single-thread score of 4,394 suggests a scaling efficiency of roughly 8.8x across the 14 cores, which is reasonable for a chip without hyperthreading. The data compression score of 400,942 stands out as a peak, indicating that the compression workload benefits strongly from the cache and core arrangement. The prime number test at 365 is comparatively low, suggesting that this workload does not play to the architecture's strengths.

The nearest rival data provides context for the average score of 48,995. The AMD Ryzen 7 PRO 5755G is 0.4% higher, the AMD Ryzen 9 7900 is 0.5% higher, the Intel Xeon Gold 5318H is 0.6% lower, and the Intel Core i5-14600K is 0.8% lower. These deltas are all under 1%, meaning the Core Ultra 5 245 performs within a narrow band of its closest competitors. The 90th percentile placement indicates that, despite the tight clustering, it sits above the vast majority of all CPUs in the database.

The Verdict

The data supports a clear division. The Intel Core Ultra 5 245 is the only one of the two with measured performance, so any workload requiring benchmark-verified results points to Intel. Its 90th percentile rank and average score of 48,995 place it among the top 10% of all processors, and its nearest rivals all fall within 0.8% of its score, indicating consistent performance across a range of comparable chips.

The AMD Ryzen Embedded 9900X offers specifications that suggest different strengths, but without benchmark scores, those strengths remain unquantified. Its 12 cores and 24 threads provide more logical threads than the Intel part's 14 cores and 14 threads, which could benefit heavily threaded workloads. Its 64 MB L3 cache is more than double the Intel part's 24 MB, which could reduce memory latency for cache-resident data. Its 5.60 GHz boost clock is higher than the Intel part's 5.10 GHz, which could improve single-threaded responsiveness. Its 120 W TDP is higher than the Intel part's 65 W, which allows more sustained power draw but also implies higher cooling requirements.

For users who need measured performance data, the Intel Core Ultra 5 245 is the only choice with recorded results. For users who prioritize thread count and cache capacity, the AMD part presents a compelling specification sheet, but the absence of benchmark data means its real-world performance cannot be verified from the database. The verdict is straightforward: the Intel part wins on evidence, the AMD part wins on paper, and the gap between those two positions cannot be resolved without additional measurements.
