AMD Ryzen 7 5700X3D vs AMD Ryzen 9 6900HS Comparison

Head-to-Head Benchmarks

The benchmark data reveals a fascinating split between these two eight-core, sixteen-thread processors. The AMD Ryzen 7 5700X3D wins 13 of the 23 recorded head-to-head comparisons, while the AMD Ryzen 9 6900HS takes 10. The margins, however, tell a more nuanced story than the raw win count.

The most dramatic result in the entire comparison comes from Cinebench R23 single-core, where the Ryzen 7 5700X3D posts a score of 3157 against the Ryzen 9 6900HS's 1554. That is a 103.2% advantage, meaning the desktop chip more than doubles the mobile chip's score in this particular test. The Cinebench R23 multi-core result is nearly as lopsided: 22366 versus 13445, a 66.4% lead for the Ryzen 7 5700X3D. These are not small margins; they represent fundamental differences in sustained performance capability.

The Ryzen 7 5700X3D also dominates in the PassMark physics test, scoring 2686 against just 1041 for the Ryzen 9 6900HS, a 158% difference. The find-prime-numbers workload shows an even larger percentage gap: 224 versus 58, which works out to a 286.2% advantage. This workload clearly favors the desktop processor's architecture and power envelope.

Geekbench results also favor the Ryzen 7 5700X3D, though less dramatically. The multi-core score of 11086 beats 9451 by 17.3%, while the single-core score of 1849 beats 1733 by 6.7%. Cinebench R15 tells a similar story: the multi-core score of 2254 beats 2161 by 4.3%, and the single-core score of 318 beats 245 by 29.8%.

The Ryzen 9 6900HS, however, has its own set of victories. The 3DMark suite is entirely in its favor. It wins the 16-thread test with 6963 versus 6764, a 2.9% margin, and the max-thread test with 6955 versus 6755, also 2.9%. The low-thread-count 3DMark tests show larger advantages: the 2-thread test goes 1761 to 1575 (10.6%), the 4-thread test goes 3427 to 3097 (9.6%), and the 8-thread test goes 5830 to 5357 (8.1%). The single-thread 3DMark result is the mobile chip's best 3DMark showing at 915 versus 804, a 12.1% edge.

PassMark integer math favors the Ryzen 9 6900HS at 86449 versus 81257, a 6% lead, and floating-point math goes to the mobile chip at 48239 versus 46492, a 3.6% margin. PassMark single-thread also goes to the Ryzen 9 6900HS: 3237 versus 2970, an 8.2% edge in both the single-thread and singlethread entries.

Where Each One Wins

The data paints a clear picture of workload specialization. The Ryzen 7 5700X3D is the stronger choice for heavily threaded rendering and compute workloads. Its Cinebench R23 multi-core score of 22366 is 66.4% ahead, and the PassMark multithread score of 26318 beats 23152 by 13.7%. The 158% lead in the physics test and the 286.2% lead in prime-number finding suggest the desktop chip excels at workloads that stress sustained integer throughput across all cores.

Data compression and encryption also favor the Ryzen 7 5700X3D, with scores of 307237 versus 292842 (4.9%) and 18788 versus 18303 (2.6%) respectively. Extended instruction workloads go to the desktop chip by 5.9% (21202 versus 20015), and random string sorting goes to it by 3.2% (31492 versus 30528).

The Ryzen 9 6900HS, by contrast, shows its strength in lighter-threaded workloads and in the 3DMark suite. Its sweep of all six 3DMark tests, with margins ranging from 2.9% to 12.1%, suggests it handles graphics-related API workloads more efficiently at every thread count. The PassMark single-thread score of 3237 versus 2970 (8.2%) indicates the mobile chip has higher per-core throughput in some integer workloads, and the integer and floating-point math results confirm this: 86449 versus 81257 (6%) and 48239 versus 46492 (3.6%).

The pattern here is that the Ryzen 9 6900HS wins where clock speed and per-core efficiency matter most, while the Ryzen 7 5700X3D wins where cache capacity and sustained multi-core output matter. The desktop chip's 96 MB of shared L3 cache versus the mobile chip's 16 MB is the most plausible explanation for the massive gaps in Cinebench R23 and physics workloads.

Specification Differences

The two processors differ across nearly every major specification category. The Ryzen 7 5700X3D has a base clock of 3.00 GHz and a boost clock of 4.10 GHz, while the Ryzen 9 6900HS runs at 3.30 GHz base and 4.90 GHz boost. Despite the mobile chip's higher clocks, the desktop chip still wins most multi-core benchmarks.

Thermal design power differs substantially: the Ryzen 7 5700X3D carries a 105 W TDP, while the Ryzen 9 6900HS is rated at 35 W, reflecting its mobile positioning. The socket is another major divider: the Ryzen 7 5700X3D uses AMD Socket AM4, while the Ryzen 9 6900HS uses AMD Socket FP7.

Memory support is generational. The Ryzen 7 5700X3D supports DDR4 with dual-channel operation and 51.2 GB/s memory bandwidth, and it supports ECC memory. The Ryzen 9 6900HS supports DDR5, also dual-channel, but with a higher 76.8 GB/s memory bandwidth and no ECC support.

The Ryzen 7 5700X3D has no integrated graphics, while the Ryzen 9 6900HS includes Radeon 680M graphics. Both use PCIe Gen 4 with 20 lanes from the CPU. The Ryzen 7 5700X3D was released on 2024-01-07 with a launch MSRP of $249, while the Ryzen 9 6900HS has no recorded release date or launch MSRP in the database.

Architecture Differences

The architectural split here is more than just a node shrink. The Ryzen 7 5700X3D uses Zen 3 architecture under the Vermeer codename, built on a 7 nm process at TSMC with 8,850 million transistors on a 74 mm² die. The Ryzen 9 6900HS uses Zen 3+ architecture under the Rembrandt codename, built on a 6 nm process at TSMC with a 208 mm² die size.

Cache configuration is the defining difference. The Ryzen 7 5700X3D has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 96 MB of shared L3 cache. The Ryzen 9 6900HS matches the per-core L1 and L2 figures, but its shared L3 cache is only 16 MB. That sixfold difference in L3 capacity is the most likely driver behind the Ryzen 7 5700X3D's massive wins in cache-sensitive workloads like Cinebench R23 multi-core and PassMark physics.

The Ryzen 7 5700X3D belongs to the 5000 series and is marketed as a desktop part, while the Ryzen 9 6900HS belongs to the 6000 series and targets the mobile segment. The Ryzen 9 6900HS also has a larger die despite the smaller process node, which reflects the integrated Radeon 680M graphics and the DDR5 memory controller. The Ryzen 7 5700X3D has no integrated graphics and uses the older DDR4 memory standard, which trades memory bandwidth for the massive L3 cache allocation.

Both processors are currently marked as Active in production status, and neither has an unlocked multiplier. The Ryzen 7 5700X3D's part number is 100-000001503100-100001503WOF, while the Ryzen 9 6900HS uses 100-000000545100-000000561. The transistor count for the Ryzen 9 6900HS is not recorded in the database, and its release date is also unrecorded, which limits direct timeline comparisons between the two parts.
