AMD Ryzen Embedded 9900X vs Intel Core Ultra 5 238V Comparison

Head-to-Head Benchmarks

The database contains no overlapping benchmark records for the AMD Ryzen Embedded 9900X and the Intel Core Ultra 5 238V. The AMD part has an empty benchmark array, while the Intel chip has 17 recorded test scores. Direct head-to-head deltas cannot be computed from the recorded data. What can be analyzed is the Intel part's absolute performance and its position against the nearest rivals listed in the database, alongside the architectural capacity of the AMD part.

The Intel Core Ultra 5 238V posts an average benchmark score of 21,981. This places it at the 75th percentile of all CPUs in the database. Its nearest rival, the Intel Core i7-11700F, averages 21,988, a delta of 0 percent. The AMD Ryzen 5 3600X averages 21,992, also a 0 percent delta. The Intel Core Ultra 5 236V trails by 0.1 percent with an average of 21,952. The AMD EPYC 9534 scores 21,900, a 0.4 percent gap. The 238V essentially sits at parity with three of these rivals and slightly ahead of the EPYC 9534. The largest recorded advantage over a listed rival is 0.4 percent, which is within measurement noise for most workloads.

The AMD Ryzen Embedded 9900X has no benchmark scores in the database, so its average benchmark score is recorded as 0, and its percentile versus all CPUs is 50. The absence of recorded results means no quantitative comparison of compute performance is possible from the database. The Intel part's strongest single benchmark result is in PassMark data compression at 176,532. Its Cinebench R23 multi-core score is 15,645, and its single-core score is 2,208. The R20 results are 6,570 multi-core and 927 single-core. The R15 results are 1,576 multi-core and 222 single-core.

In PassMark integer math, the Intel chip scores 38,889. Floating point math scores 53,160. Extended instructions score 15,377. Find prime numbers scores 174. Random string sorting scores 21,585. The multithread score is 18,407, and the single-thread score is 3,890. Data encryption scores 13,072, and physics scores 1,546.

The AMD part's specifications indicate it should produce far higher multi-threaded scores than the Intel part if benchmarked, because it has 12 cores and 24 threads versus 8 cores and 8 threads. The AMD chip also has a 64 MB L3 cache versus 8 MB shared L3 on the Intel chip. These are structural differences, not measured results. The database does not confirm any performance advantage numerically because the AMD chip has no recorded scores.

Where Each One Wins

The Intel Core Ultra 5 238V wins in every category where recorded data exists, simply because the AMD Ryzen Embedded 9900X has no benchmark entries. The Intel chip's 17 scores cover Cinebench R15, R20, and R23 in both single and multi-core variants, plus seven PassMark workload tests. Each of these is a measurable win for the Intel part in the database as it currently stands.

The AMD part's strengths are architectural and configurational. It supports ECC memory, which the Intel part does not. It offers 24 PCIe Gen 5 lanes from the CPU, while the Intel part offers 4 PCIe Gen 5 lanes. The AMD chip has a 120 W TDP, which indicates a higher sustained power envelope than the Intel chip's 17 W TDP. The AMD chip uses a dual-chiplet design with a die size of 2x 70.6 mm², while the Intel die size is not recorded.

The AMD chip has a higher base clock of 4.40 GHz versus 2.10 GHz, and a higher boost clock of 5.60 GHz versus 4.70 GHz. The AMD chip has 16,630 million transistors, while the Intel transistor count is not recorded. The AMD chip is unlocked, meaning the multiplier can be adjusted. The Intel chip has a locked multiplier.

For workloads that depend on single-thread latency, the AMD chip's higher boost clock suggests an advantage, but no measured score exists to confirm it. For workloads that depend on memory bandwidth, the AMD chip lists 89.6 GB/s of dual-channel DDR5 bandwidth, while the Intel part has no bandwidth figure recorded. For workloads that depend on cache capacity, the AMD chip's 64 MB L3 cache is eight times larger than the Intel chip's 8 MB shared L3.

The Intel chip does have a larger L1 cache per core at 192 KB versus 80 KB on the AMD chip, and a larger L2 cache per core at 2.5 MB versus 1 MB. The Intel chip integrates Arc 130V graphics, while the AMD chip integrates Radeon Graphics. Neither integrated GPU has benchmark scores in the database.

The Intel chip is a mobile part with a 17 W TDP and a BGA 2833 socket, meaning it is soldered and not upgradeable. The AMD chip is a desktop part with an AM5 socket, 120 W TDP, and an unlocked multiplier, meaning it can be replaced or overclocked by the system builder.
