Where Each One Wins

The recorded benchmark data shows a clear split in strengths between the two processors. The Intel Arc G3 EXTREME dominates the AMD Ryzen Embedded 9900X in every benchmark test present in the database, with all scores recorded for the Intel part. The AMD part has no benchmark entries in the database, resulting in zero wins for the AMD processor and a full sweep for the Intel processor.

The Intel Arc G3 EXTREME's wins span multiple workload categories. In Cinebench tests, the Intel part scores 2192 in R15 multicore, 10945 in R20 multicore, and 14655 in R23 multicore. Single-core results follow a similar pattern: 267 in R15 single-core, 1545 in R20 single-core, and 1862 in R23 single-core. These scores place the Intel processor at the 85th percentile among all CPUs in the database, with an average benchmark score of 36699.

PassMark results reinforce the Intel part's dominance. The data compression score of 307094, the floating-point math score of 86929, and the integer math score of 71164 each represent substantial computational throughput. The extended instructions score of 24017 and the random string sorting score of 37331 indicate strong performance in specific algorithmic tasks. The multithread score of 30659 and the single-thread score of 4293 further confirm the Intel processor's capability across both parallel and sequential workloads.

The AMD Ryzen Embedded 9900X, despite its higher core count, threads, and clock speeds, has no recorded benchmark scores in the database. Its percentile ranking of 50 and average benchmark score of 0 reflect this absence of data. Consequently, the use-case split is one-sided: the Intel Arc G3 EXTREME is the only processor with measurable performance evidence, while the AMD part's capabilities remain unquantified in this database.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename and belongs to the Ryzen Embedded generation based on Zen 5 architecture. The Intel Arc G3 EXTREME uses the Panther Lake codename and belongs to the Arc G3 generation.

The manufacturing processes differ significantly. AMD relies on TSMC's 4 nm node, while Intel uses its own 3 nm process. The AMD part integrates 16,630 million transistors across a die size of 2x 70.6 mm². The Intel part has no recorded transistor count or die size in the database.

Cache hierarchies show distinct designs. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Intel processor has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Intel part's larger per-core L1 and L2 allocations contrast with the AMD part's larger total L3 capacity.

Memory support reflects different target platforms. The AMD processor uses DDR5 memory with a dual-channel bus and 89.6 GB/s bandwidth, plus ECC support. The Intel processor uses LPDDR5X memory with dual-channel configuration and 136.5 GB/s bandwidth, without ECC support. PCIe connectivity also differs: the AMD part provides Gen 5 with 24 lanes (CPU only), while the Intel part provides Gen 5 with 4 lanes (CPU only).

Integrated graphics differentiate the two. The AMD processor includes Radeon Graphics, while the Intel processor includes Arc B390 graphics. The Intel part's integrated graphics carry the Arc branding, suggesting a more prominent GPU component.

The Intel Arc G3 EXTREME is classified as a mobile processor with an Intel BGA 2540 socket, while the AMD Ryzen Embedded 9900X is a desktop processor with AMD Socket AM5. The AMD part has an unlocked multiplier, whereas the Intel part does not.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries comparing the two processors directly. All recorded benchmark scores belong exclusively to the Intel Arc G3 EXTREME, with the AMD Ryzen Embedded 9900X having no benchmark data whatsoever.

For the Intel Arc G3 EXTREME, the most significant Cinebench results show a multicore score of 14655 in R23 and a single-core score of 1862 in the same test. The R20 multicore score of 10945 and R15 multicore score of 2192 demonstrate scaling across different test versions. The single-core progression from 267 in R15 to 1545 in R20 to 1862 in R23 reflects consistent performance across test generations.

PassMark results for the Intel part are spread across multiple specialized workloads. The data compression score of 307094 is the highest single metric, followed by floating-point math at 86929 and integer math at 71164. Extended instructions score 24017, random string sorting scores 37331, and data encryption scores 23881. The multithread score of 30659 and single-thread score of 4293 (recorded twice under slightly different test names) round out the profile. The physics score of 2515 and the find prime numbers score of 248 complete the set.

The Intel Arc G3 EXTREME's average benchmark score of 36699 places it at the 85th percentile among all CPUs. Its nearest rivals in the database include the Intel Core Ultra 5 225 with an average score of 36938 and a delta of -0.6%, the AMD Ryzen 5 5600F at 36945 with -0.7%, the AMD Ryzen 5 5500X3D at 37018 with -0.9%, and the AMD Ryzen AI 7 PRO 450 at 37093 with -1.1%. These negative delta percentages indicate that the Intel Arc G3 EXTREME scores slightly below each of these rivals, with the closest competitor being the Intel Core Ultra 5 225, which outperforms it by 0.6%.

The AMD Ryzen Embedded 9900X has no benchmark scores, no nearest rivals, and an average benchmark score of 0. Its percentile ranking of 50 is a default value reflecting the absence of performance data rather than a measured performance level. The recorded data therefore provides no basis for comparing the AMD part's measured performance against the Intel part's measured performance.
