Head-to-Head Benchmarks

The database contains benchmark data only for the Intel Core 3 305. The AMD Ryzen Embedded 9900X has no recorded benchmark scores, no average benchmark score, and no nearest rivals listed. The Intel chip has an average benchmark score of 18,302.

For the Intel Core 3 305, Cinebench R15 multi-core scored 1,322 and single-core scored 186. Cinebench R20 multi-core scored 5,511 and single-core scored 777. Cinebench R23 multi-core scored 13,123 and single-core scored 1,852.

In PassMark tests, the Intel chip shows strong results in data compression with a score of 146,857, data encryption at 11,019, and extended instructions at 13,543. Integer math scored 32,295, floating point math scored 42,284, and find prime numbers scored 115. The multithread score reached 15,439, physics scored 1,233, random string sorting scored 17,623, and single-thread performance scored 3,977.

The nearest rivals for the Intel Core 3 305 are all within a narrow band. The Intel Core i3-14100 has an average score of 18,318, which is 0.1% higher than the Core 3 305. The Intel Core 5 330 scores 18,345, 0.2% higher. The Intel Core 7 360 scores 18,374, 0.4% higher. The AMD Ryzen 5 2600E scores 18,230, which is 0.4% lower. This places the Core 3 305 in a tightly contested performance cluster where the differences are minimal.

Because the AMD Ryzen Embedded 9900X has no benchmark entries, no head-to-head comparison scores exist in the database. The wins count is zero for both processors, and the head-to-head benchmark array is empty. The data cannot confirm any performance advantage for either chip through direct measurement.

The Verdict

The database shows a clear separation between these two processors in positioning and specifications, but no direct benchmark comparison is possible. The AMD Ryzen Embedded 9900X offers 12 cores, 24 threads, a 5.60 GHz boost clock, 64 MB of L3 cache, dual-channel memory, ECC support, and PCIe Gen 5. The Intel Core 3 305 offers 6 cores, 6 threads, a 4.30 GHz boost clock, 6 MB of shared L3 cache, single-channel memory, no ECC support, and PCIe Gen 4.

The Intel Core 3 305 has recorded performance data and sits in the 72nd percentile, with an average benchmark score of 18,302. Its nearest rivals all score within 0.4% of it, indicating a tightly grouped competitive tier. The AMD Ryzen Embedded 9900X has no recorded benchmark scores and sits in the 50th percentile, which reflects unmeasured or unrated status rather than actual performance.

For users who need measured performance data, the Intel chip has the only available numbers. For users who need maximum core count, thread count, cache capacity, memory bandwidth, and PCIe capabilities, the AMD chip has the stronger specifications on paper. The Intel chip targets mobile systems with a 15 TDP, while the AMD chip targets desktop systems with a 120 TDP.

Where Each One Wins

The AMD Ryzen Embedded 9900X wins on raw specification strength. Its 24 threads double the Intel chip's thread count. The 64 MB L3 cache is substantially larger than the 6 MB shared cache on the Intel chip. Dual-channel memory with 89.6 GB/s bandwidth exceeds the Intel chip's single-channel 59.7 GB/s. PCIe Gen 5 with 24 lanes outperforms PCIe Gen 4 with 6 lanes. ECC memory support is present on AMD and absent on Intel. The unlocked multiplier allows overclocking, while the Intel chip is locked.

The Intel Core 3 305 wins on measured benchmark availability and efficiency. It has 17 recorded benchmark scores across Cinebench and PassMark tests. Its 72nd percentile ranking among all CPUs indicates it performs well relative to the broader processor landscape. The nearest rivals show it within 0.4% of the Core i3-14100, Core 5 330, Core 7 360, and Ryzen 5 2600E. The 15 TDP makes it suitable for low-power mobile applications, and the 3 nm Intel process node is smaller than the AMD 4 nm TSMC node.

The Intel chip also wins on memory flexibility with LPDDR5X support in addition to DDR5. The AMD chip supports only DDR5. The Intel chip has a later release date of April 15, 2026, compared to October 6, 2025 for AMD.

For workloads that depend on multi-threading, large shared cache, high memory bandwidth, and PCIe expansion, the AMD specifications point to advantages. For workloads where measured single-thread and multi-thread scores matter, and where power consumption is critical, the Intel data provides the only recorded evidence. The database contains no benchmark results for the AMD chip, so any performance claim about it remains unverified.
