AMD Ryzen 7 9700X vs AMD Ryzen Embedded 9900X3D Comparison

The Verdict

The data presents an unusual comparison. The AMD Ryzen 7 9700X has a complete benchmark record, while the AMD Ryzen Embedded 9900X3D has no recorded benchmark scores, no average score, and no nearest rivals in the database. The 9700X sits at the 86th percentile of all CPUs with an average benchmark score of 37,943. The 9900X3D sits at the 50th percentile with an average score of 0. Benchmark results indicate that the 9700X is the only part in this pairing with measurable performance data.

For workloads covered by the recorded tests, the Ryzen 7 9700X is the only choice supported by evidence. The 9900X3D cannot be evaluated on performance grounds from the database. The 9900X3D does offer a higher core count (12 versus 8), higher base clock (4.40 GHz versus 3.80 GHz), a larger L3 cache (128 MB versus 32 MB), and a higher TDP (120 watts versus 65 watts). However, without any benchmark scores, the database cannot confirm whether those specifications translate into faster execution in any test.

The 9700X also has a launch MSRP of $359. The 9900X3D has no recorded launch MSRP. The 9700X is a desktop part released on 2024-08-07, while the 9900X3D is an embedded part released on 2025-10-06. The 9700X has an unlocked multiplier, and so does the 9900X3D. Buyers should note that the 9700X is the only part with verified performance data in the database, and the 9900X3D remains an unmeasured quantity.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, with zero wins recorded for either CPU. The 9900X3D has no benchmark entries at all, which makes a direct comparison impossible on a test-by-test basis. The 9700X, however, has a full suite of scores that can be examined on its own.

The 9700X's multi-threaded performance is documented across several tests. In Cinebench R23 multicore, it scores 20,485. In Cinebench R15 multicore, it scores 3,178. Geekbench multicore shows 17,906. The PassMark multithread test shows 37,161. The 3DMark 16-thread test shows 9,824, and the 3DMark max-thread test shows 9,771. The 3DMark 8-thread test shows 8,184, the 4-thread test shows 4,869, and the 2-thread test shows 2,525.

Single-thread performance for the 9700X is also recorded. The 3DMark single-thread test shows 1,280. Cinebench R23 singlecore shows 2,211. Cinebench R15 singlecore shows 346. Geekbench singlecore shows 3,023. PassMark single thread shows 4,654.

Specialized workloads show strong results for the 9700X. PassMark floating point math scores 78,999. PassMark integer math scores 120,142. PassMark extended instructions scores 35,318. PassMark data compression scores 437,140. PassMark data encryption scores 21,815. PassMark random string sorting scores 46,782. PassMark physics scores 2,241. PassMark find prime numbers scores 192.

The 9700X's nearest rivals in the database are all close in average score. Intel Core i9-14901E sits at 37,911 (a 0.1% delta), AMD Ryzen AI 9 HX 370 sits at 37,904 (0.1% delta), Intel Core 5 211E sits at 37,829 (0.3% delta), and AMD Ryzen AI Embedded P132 sits at 37,804 (0.4% delta). The 9700X leads all of these by a small margin, with its 37,943 average score being 0.1% ahead of the nearest rival.

Because the 9900X3D has no scores, the database cannot show any test where it beats the 9700X. The only meaningful head-to-head statement is that the 9700X has data and the 9900X3D does not.

Specification Differences

The two CPUs differ in several key specifications. The 9700X has 8 cores and 16 threads, while the 9900X3D has 12 cores and 24 threads. Base clock speeds differ: 3.80 GHz for the 9700X versus 4.40 GHz for the 9900X3D. Boost clocks are identical at 5.50 GHz.

TDP differs significantly. The 9700X has a 65 watt TDP, while the 9900X3D has a 120 watt TDP. Both use the same socket (AMD Socket AM5) and the same process node (4 nm at TSMC). The 9700X has a single die of 70.6 mm² with 8,315 million transistors. The 9900X3D has two dies of 70.6 mm² each (2x 70.6 mm²) with 16,630 million transistors.

L3 cache differs: 32 MB for the 9700X versus 128 MB for the 9900X3D. L1 cache is the same at 80 KB per core, and L2 cache is the same at 1 MB per core. Memory support is identical: DDR5, dual-channel, 89.6 GB/s bandwidth, and ECC support. PCIe is the same: Gen 5 with 24 lanes (CPU only). Both have integrated Radeon Graphics.

The 9700X has a launch MSRP of $359. The 9900X3D has no recorded launch MSRP. The 9700X was released on 2024-08-07, and the 9900X3D on 2025-10-06. Both have unlocked multipliers. The 9700X part number is 100-000001404, and the 9900X3D part number is 100-000001368E.

Where Each One Wins

The Ryzen 7 9700X wins every category where performance data exists. In multi-threaded workloads, its Cinebench R23 multicore score of 20,485 and Geekbench multicore score of 17,906 indicate strong scaling across 8 cores. In single-threaded workloads, the 3DMark single-thread score of 1,280 and PassMark single thread score of 4,654 show solid per-core performance. In specialized tasks, the PassMark integer math score of 120,142 and floating point math score of 78,999 indicate broad computational strength.

The Ryzen Embedded 9900X3D has no recorded wins because the database contains no benchmark scores for it. Its specification sheet suggests potential advantages in core-heavy workloads: 12 cores versus 8, and 128 MB of L3 cache versus 32 MB. The higher base clock of 4.40 GHz could also benefit lightly threaded tasks. However, the database cannot confirm any of these potential advantages with measured results. The 9900X3D's percentile rank of 50 with an average score of 0 places it below the 9700X's 86th percentile, but that rank is a placeholder for missing data rather than a measured position.

For any workload represented in the database, the 9700X is the only part with verified scores. Users who rely on benchmark data should treat the 9900X3D as an unmeasured part until the database records its performance.

Architecture Differences

Both CPUs belong to the 9000 series and share the Granite Ridge codename. The 9700X is listed under the Ryzen 7 generation, described as Zen 5 (Granite Ridge). The 9900X3D is listed under the Ryzen Embedded generation, also described as Zen 5 (Granite Ridge). The 9700X has an architecture field of Zen 5, while the 9900X3D has a null architecture field in the database, though its generation string confirms Zen 5.

The process node is identical: 4 nm at TSMC. The 9700X uses a single chiplet with a die size of 70.6 mm² and 8,315 million transistors. The 9900X3D uses a dual-chiplet design with 2x 70.6 mm² and 16,630 million transistors. This doubles the transistor count and die area for the 9900X3D.

Cache architecture differs in L3 capacity. The 9700X has 32 MB of shared L3 cache. The 9900X3D has 128 MB of L3 cache, which is four times larger. L1 and L2 caches are identical at 80 KB per core and 1 MB per core respectively. The database does not record a 3D V-Cache field for either CPU, so the larger L3 cache on the 9900X3D cannot be attributed to that specific technology.

Both CPUs support the same memory architecture: DDR5, dual-channel, 89.6 GB/s bandwidth, and ECC memory. Both have the same PCIe configuration: Gen 5 with 24 lanes (CPU only). Both include integrated Radeon Graphics. The 9900X3D carries the Embedded designation, which typically indicates a different qualification and reliability profile, but the database records the market segment for both as Desktop and both have Active production status. The 9900X3D's TDP of 120 watts versus the 9700X's 65 watts suggests a higher power envelope for the embedded part.
