AMD Ryzen Embedded 9900X3D vs Intel Arc G3 EXTREME Comparison

The Verdict

The AMD Ryzen Embedded 9900X3D and the Intel Arc G3 EXTREME serve fundamentally different markets despite both being current-generation parts. The AMD chip is a 12-core, 24-thread desktop processor built for Socket AM5 with a 120 W TDP, while the Intel part is a 14-core, 14-thread mobile processor on BGA 2540 with a 25 W TDP. The database contains no benchmark records for the AMD 9900X3D, so its average benchmark score is recorded as zero and its percentile versus all CPUs is 50. The Intel Arc G3 EXTREME, by contrast, has a full benchmark suite recorded, an average score of 36,699, and an 85th percentile ranking among all CPUs.

Given the data available, the Intel Arc G3 EXTREME is the only one of the two that can be quantitatively assessed. It sits within 1.1% of several established desktop and mobile processors, including the Intel Core Ultra 5 225, AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, and AMD Ryzen AI 7 PRO 450. The AMD 9900X3D, lacking recorded measurements, cannot be placed relative to those rivals. For workloads that rely on the specific benchmark scores present in the database, the Intel part delivers measurable results; for the AMD part, the database shows no comparable data points.

The practical takeaway from the recorded data is straightforward: the Intel Arc G3 EXTREME has verified performance across Cinebench and Passmark tests, and its percentile ranking indicates it outperforms roughly 85% of all CPUs in the database. The AMD Ryzen Embedded 9900X3D, despite its higher core count, larger cache, and higher clock speeds on paper, has no recorded benchmark evidence. Any user comparing these two strictly on the basis of measured results must favor the Intel part simply because it has results. The AMD chip remains an unquantified entry.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen Embedded 9900X3D uses TSMC's 4 nm process and is built on the Granite Ridge codename with Zen 5 architecture, belonging to the Ryzen Embedded (Zen 5 (Granite Ridge)) generation. The Intel Arc G3 EXTREME uses Intel's own 3 nm process with the Panther Lake codename and belongs to the Arc G3 (Panther Lake) generation. Both are actively in production.

Core and thread counts differ significantly. The AMD part has 12 cores and 24 threads, meaning simultaneous multithreading is enabled. The Intel part has 14 cores and 14 threads, with no multithreading per core. The Intel chip has more physical cores, but the AMD chip processes more threads total.

Clock speeds also diverge. The AMD processor has a 4.40 GHz base clock and a 5.50 GHz boost clock. The Intel processor has a 1.90 GHz base clock and a 4.70 GHz boost clock. The AMD part is substantially higher in both metrics.

Cache hierarchies are structured differently. The AMD chip uses 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel chip uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel part has larger per-core L1 and L2 allocations, while the AMD part has more than seven times the total L3 capacity.

Memory support differs by type. The AMD processor supports DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth and ECC memory support. The Intel processor supports LPDDR5X over a dual-channel bus with 136.5 GB/s of bandwidth and no ECC support. The Intel part has roughly 52% more memory bandwidth on paper.

PCIe connectivity is not equal. The AMD chip provides Gen 5 with 24 lanes from the CPU. The Intel chip provides Gen 5 with only 4 lanes. Integrated graphics differ as well: the AMD part includes Radeon Graphics, while the Intel part includes Arc B390 graphics. The AMD processor has an unlocked multiplier, the Intel processor does not. The AMD part is classified as a desktop segment product, the Intel part as mobile.

Where Each One Wins

The Intel Arc G3 EXTREME is the only processor in this comparison with recorded benchmark data, so it wins every measurable category by default. Its Cinebench R23 multi-core score is 14,655, its single-core score is 1,862. In Passmark tests, it scores 30,659 in multithread, 4,293 in single-thread, 86,929 in floating point math, 71,164 in integer math, and 307,094 in data compression. It also scores 23,881 in data encryption, 24,017 in extended instructions, 2515 in physics, 37,331 in random string sorting, and 248 in find prime numbers.

The AMD Ryzen Embedded 9900X3D has no recorded wins because the database contains no benchmarks for it. On paper, the AMD part should dominate in any workload that scales with thread count, given 24 threads versus 14, higher clocks, and a massive 128 MB L3 cache. The 5.50 GHz boost clock is 0.80 GHz above the Intel part's 4.70 GHz boost. The 120 W TDP indicates far more headroom for sustained multi-core loads, while the Intel part's 25 W TDP suits constrained mobile environments.

The Intel part wins in efficiency-oriented scenarios, at least by specification: 25 W versus 120 W is a fivefold difference in power envelope. It also wins in memory bandwidth, with 136.5 GB/s versus 89.6 GB/s, and it has more physical cores. The AMD part wins in thread count, cache size, clock speed, PCIe lane count, ECC support, and socket flexibility, as AM5 is a desktop socket while BGA 2540 is soldered.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark entries for these two processors, and the AMD side has no individual benchmark scores. The only comparable data belongs to the Intel Arc G3 EXTREME, so the analysis must rely on its recorded results versus its nearest rivals.

The Intel Arc G3 EXTREME's strongest recorded result is Passmark data compression at 307,094. Its floating point math score of 86,929 and integer math score of 71,164 show a heavy skew toward floating-point throughput, which is common for graphics-adjacent architectures like the integrated Arc B390. The Cinebench R23 multi-core score of 14,655 and single-core score of 1,862 indicate a ratio of roughly 7.9 to 1 between multi-threaded and single-threaded performance, which is modest for a 14-core part without SMT.

In Cinebench R20, the Intel part scores 10,945 multi-core and 1,545 single-core. In Cinebench R15, it scores 2,192 multi-core and 267 single-core. The scaling from R15 to R20 to R23 reflects both the workload changes and the processor's ability to maintain performance across test revisions. The R23 multi-core score of 14,655 places it within 1.1% of the AMD Ryzen AI 7 PRO 450, which averages 37,093 overall, and within 0.6% of the Intel Core Ultra 5 225, which averages 36,938.

Passmark single-thread results show a score of 4,293, recorded under two test names in the database, passmark_single_thread and passmark_singlethread, with identical values. The multithread Passmark score is 30,659, giving a multi-to-single ratio of about 7.1 to 1. The extended instructions score of 24,017 and encryption score of 23,881 are close, suggesting balanced SIMD and cryptographic throughput. Physics score is 2,515, random string sorting is 37,331, and find prime numbers is 248, the lowest recorded score.

Against its nearest rivals, the Intel part is essentially tied. The delta percentages are all negative, meaning the Intel part is slightly slower than each rival in average score, but the margins are tiny: 0.6%, 0.7%, 0.9%, and 1.1%. These differences fall within normal run-to-run variation for most benchmark suites. The 85th percentile ranking confirms that the Intel part sits above the median CPU in the database, but its nearest rivals cluster tightly around the same performance level.

For the AMD Ryzen Embedded 9900X3D, no comparable numbers exist. The database records zero benchmark scores, zero wins in any head-to-head comparison, and a 50th percentile ranking that reflects the absence of data rather than measured performance. The 50th percentile is the default middle position for an unmeasured part. Without Cinebench or Passmark results, there is no way to state how it would fare against the Intel part or any of the Intel part's rivals.
