AMD Ryzen 9 9900X3D vs AMD Ryzen Embedded 9700X Comparison

Where Each One Wins

The data splits cleanly between the two processors based on core count, cache size, and market positioning. The AMD Ryzen 9 9900X3D is a desktop flagship with 12 cores, 24 threads, and a massive 128 MB L3 cache, while the AMD Ryzen Embedded 9700X is an 8-core, 16-thread part with 32 MB of shared L3 cache. The 9900X3D holds all recorded benchmark scores in the database, as the 9700X has no benchmark entries listed. This means the 9900X3D wins every measured workload, from single-threaded tasks to heavily multithreaded rendering and physics simulations.

The 9900X3D delivers a single-thread score of 1269 in 3DMark, a multicore score of 22884 in Geekbench, and a Cinebench R23 multicore result of 47737. The 9700X, with no recorded benchmarks, cannot be compared numerically in any test. For users prioritizing raw compute throughput, the 9900X3D is the only option with measurable data. The 9700X, by contrast, targets embedded applications where lower power consumption (65 W TDP versus 120 W) and a smaller physical footprint matter more than peak performance. The 9700X still uses the same Zen 5 architecture and Granite Ridge codename, so it inherits the same instruction set and efficiency traits, but its smaller core count and cache size limit its multi-threaded ceiling.

Architecture Differences

Both processors share the Zen 5 architecture, the Granite Ridge codename, and a 4 nm TSMC process node, but they diverge significantly in physical construction and feature allocation. The 9900X3D uses a dual-chiplet design with a die size of 2x 70.6 mm² and 16,630 million transistors, while the 9700X uses a single 70.6 mm² die with 8,315 million transistors. That is exactly half the transistor count and half the die area, which explains the core count difference: 12 cores versus 8 cores.

The cache hierarchy differs sharply. The 9900X3D has 128 MB of L3 cache, while the 9700X has 32 MB of shared L3 cache. Both parts have 80 KB of L1 cache per core and 1 MB of L2 cache per core, but the 9900X3D's larger L3 pool is its defining feature, likely intended to improve gaming and data-heavy workloads by reducing memory latency. The 9700X, despite being an embedded variant, retains the same per-core L1 and L2 sizes, so its architectural heritage is intact, but the shared L3 is a quarter of the size.

Both chips support DDR5 memory with dual-channel bus and 89.6 GB/s bandwidth, and both support ECC memory. They also share the same PCIe Gen 5 interface with 24 lanes (CPU only) and integrated Radeon Graphics. The base clock differs: 4.40 GHz for the 9900X3D versus 3.80 GHz for the 9700X, while the boost clock is identical at 5.50 GHz. The 9900X3D has a 120 W TDP, the 9700X a 65 W TDP. Both use AMD Socket AM5 and are unlocked multipliers, but the 9700X's embedded designation suggests a focus on reliability and power efficiency in always-on or industrial environments, not necessarily overclocking headroom.

L3 cache is 128 MB on the 9900X3D and 32 MB (shared) on the 9700X.

Both share the same socket (AM5), process node (4 nm TSMC), memory support (DDR5, dual-channel, 89.6 GB/s), ECC support, PCIe Gen 5 with 24 lanes, and integrated Radeon Graphics. Both have unlocked multipliers. The release dates differ: the 9900X3D launched on January 5, 2025, while the 9700X launched on October 6, 2025. The 9900X3D has a launch MSRP of $599, while the 9700X has no listed launch MSRP in the database. The part numbers also differ: 100-000001368 for the 9900X3D and 100-000001404E for the 9700X.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two processors, and the 9700X has no individual benchmark scores listed. As a result, all measured performance data comes from the 9900X3D. The 9900X3D achieves a 3DMark max threads score of 13795, a Cinebench R23 multicore score of 47737, and a Geekbench multicore score of 22884. In PassMark, it scores 56154 in multithread, 119622 in floating point math, and 179727 in integer math.

The 9900X3D also posts strong single-thread numbers: 6739 in Cinebench R23 single-core, 3041 in Geekbench single-core, and 4646 in PassMark single-thread. Its 3DMark single-thread score is 1269. These results place the 9900X3D at the 91st percentile among all CPUs in the database, with an average benchmark score of 54762. Its nearest rivals include the Intel Core Ultra 5 245KF (average score 55093, delta -0.6%), the Intel Core Ultra 5 245K (average score 54053, delta 1.3%), the Intel Xeon 6505P (average score 53701, delta 2%), and the Intel Core i7-14700F (average score 53620, delta 2.1%). This means the 9900X3D is effectively tied with the Core Ultra 5 245KF, slightly ahead of the Core Ultra 5 245K, and about 2% ahead of the Xeon 6505P and Core i7-14700F.

Since the 9700X has no benchmark scores, the only way to interpret its position is through the 50th percentile ranking among all CPUs, with an average benchmark score of 0. That percentile figure suggests it sits near the median of the database, but without actual scores, no direct numerical comparison between the two AMD parts is possible from the recorded data.

The Verdict

The AMD Ryzen 9 9900X3D is the clear choice for any workload where measurable performance is required. It holds every benchmark score in the database, with a 91st percentile ranking and an average score of 54762. Its 12 cores, 24 threads, 128 MB of L3 cache, and 120 W TDP position it as a high-end desktop processor for multithreaded rendering, physics simulation, and data-intensive tasks. The single-thread and multi-thread results are both strong, and the nearest rival comparisons show it trading blows with Intel's Core Ultra 5 parts within a 2% band.

The AMD Ryzen Embedded 9700X, with no benchmark scores, cannot be assessed for performance from the database. Its 50th percentile ranking is the only data point, and that is derived from its specification profile rather than any measured workload. It offers 8 cores, 16 threads, 32 MB of L3 cache, and a 65 W TDP, which makes it a lower-power, lower-core-count alternative for embedded systems. It shares the same architecture, socket, memory support, and PCIe lanes, but its smaller die and cache size indicate a different design intent: efficiency and thermal restraint over peak throughput.

For users selecting between these two, the data directs them to the 9900X3D for any performance-sensitive application. The 9700X is suitable only where the 65 W TDP and embedded positioning are the deciding factors, but the database provides no benchmark evidence for its capabilities. The 9900X3D's launch MSRP is $599, and its production status is active, so it is available as a desktop part. The 9700X has no MSRP listed, and its production status is also active, but its embedded designation suggests a different deployment scenario. Without measured scores for the 9700X, the 9900X3D is the only processor in this comparison with verified performance data.
