AMD Ryzen 7 5700X3D vs AMD Ryzen 7 6800H Comparison

Head-to-Head Benchmarks

The head-to-head data shows a clear split personality between these two AMD Ryzen 7 parts. The Ryzen 7 5700X3D takes 15 of 23 benchmark wins, while the Ryzen 7 6800H counters with 8. The margins, however, tell a more nuanced story than the raw win count.

The 5700X3D dominates in heavily threaded workloads. In Cinebench R23 multicore, the desktop chip posts 22,366 against the mobile part's 13,094, a massive 41.5% advantage. The gap is nearly as stark in Cinebench R15 multicore, where the 5700X3D leads by 5.2%. PassMark multithread scoring reinforces the trend: 26,318 versus 23,060, a 12.4% edge for the 5700X3D. Even GeekBench multicore shows a substantial gap, with the 5700X3D at 11,086 compared to 9,642, a 13% margin.

The 5700X3D also crushes the 6800H in specific compute tasks. PassMark find prime numbers shows a 74.6% advantage for the desktop chip (224 versus 57), the single largest delta in the entire comparison. PassMark physics is another outlier, with the 5700X3D scoring 2,686 versus 1,046, a 61.1% lead. These results point to the 5700X3D's superior sustained throughput in integer-heavy and physics-based calculations.

The 6800H fights back in lighter-threaded and single-core scenarios. In 3DMark single-thread, the mobile chip scores 872 against 804, an 8.5% win. PassMark single-thread shows a similar pattern: 3,212 versus 2,970, an 8.1% edge. The 6800H also wins 3DMark 2-thread by 7.6% (1,695 versus 1,575) and 3DMark 4-thread by 3.8% (3,214 versus 3,097). The 8-thread test is nearly a tie, with the 6800H ahead by just 0.7%.

Interesting reversals appear in specific PassMark subtests. The 6800H wins floating point math by 3.2% (47,989 versus 46,492) and integer math by 5.1% (85,397 versus 81,257). Yet the 5700X3D counters in data compression (4.3% ahead), data encryption (2.8% ahead), extended instructions (5.1% ahead), and random string sorting (2.6% ahead). The 6800H's higher boost clock and newer architecture appear to give it an edge in certain arithmetic workloads, while the 5700X3D's large cache helps in data manipulation tasks.

Single-core Cinebench results are notably lopsided in favor of the 5700X3D, which is unexpected given the 6800H's higher clock speed. In Cinebench R23 single-core, the 5700X3D scores 3,157 versus 1,542, a 51.2% advantage. Cinebench R15 single-core shows a 23.7% lead for the 5700X3D (318 versus 242.5). These are the only single-threaded tests where the 5700X3D wins, and the margins are dramatic enough to suggest measurement conditions or platform differences play a role, possibly memory bandwidth or boost behavior.

The 3DMark threaded suite splits along expected lines. The 5700X3D wins 16-thread (6,764 versus 6,560, a 3% margin) and max-thread (6,755 versus 6,532, a 3.3% margin). The 6800H takes the 2-thread, 4-thread, and 8-thread tests. This pattern indicates the 5700X3D scales better as thread counts increase, while the 6800H holds an advantage at lower thread counts where its higher boost clock matters more.

Architecture Differences

The two processors come from different architectural generations and target different platforms. The 6800H uses Zen 3+, codenamed Rembrandt, built on TSMC's 6 nm process. The 5700X3D uses Zen 3, codenamed Vermeer, on TSMC's 7 nm node. The process node difference gives the 6800H a density and efficiency advantage, though the 5700X3D compensates with other architectural traits.

Both chips feature 8 cores and 16 threads, with identical per-core L1 (64 KB) and L2 (512 KB) cache configurations. The critical difference lies in L3 cache. The 6800H has 16 MB shared L3, while the 5700X3D offers 96 MB shared L3. That 80 MB difference, enabled by AMD's 3D V-Cache technology, is the defining architectural feature of the 5700X3D and explains its dominance in cache-sensitive workloads like data compression and physics calculations.

Clock speeds differ substantially. The 6800H runs a 3.20 GHz base clock with a 4.70 GHz boost, while the 5700X3D operates at 3.00 GHz base and 4.10 GHz boost. The 6800H's higher clocks help it win single-thread and low-thread tests, but the 5700X3D's cache advantage overrides clock speed in many multi-threaded scenarios.

Thermal design power reflects their different market segments. The 6800H is rated at 45 W TDP, a mobile-class part. The 5700X3D draws 105 W TDP, a desktop-class component. This TDP gap explains the 5700X3D's ability to sustain higher multi-threaded performance, as it has more thermal headroom to work with.

Memory support diverges sharply. The 6800H uses DDR5 memory with dual-channel support and 76.8 GB/s bandwidth. The 5700X3D uses DDR4, also dual-channel, but with 51.2 GB/s bandwidth. Despite the 6800H's higher theoretical memory bandwidth, the 5700X3D's larger cache mitigates that disadvantage in many workloads. The 6800H does not support ECC memory, while the 5700X3D does.

Integrated graphics also differ. The 6800H includes Radeon 680M graphics, making it suitable for systems without a discrete GPU. The 5700X3D has no integrated graphics, requiring a dedicated GPU. The 6800H uses AMD Socket FP7, a mobile socket, while the 5700X3D uses the desktop AM4 socket. Both support PCIe Gen 4 with 20 lanes (CPU only).

The 5700X3D's transistor count is listed at 8,850 million on a 74 mm² die. The 6800H's transistor count is not recorded, but its die size is 208 mm². The 5700X3D launched on January 7, 2024 with a launch MSRP of $249. The 6800H's release date and MSRP are not recorded in the database.

The Verdict

The data points to the 5700X3D as the stronger processor for multi-threaded and cache-intensive workloads. Its 41.5% lead in Cinebench R23 multicore, 13% edge in GeekBench multicore, and 12.4% advantage in PassMark multithread make it the clear choice for rendering, compilation, and physics simulation tasks. The 74.6% margin in prime number finding and 61.1% lead in PassMark physics reinforce this conclusion. Users running heavily threaded applications should favor the 5700X3D.

The 6800H wins where thread counts are low and clock speed matters. Its 8.5% lead in 3DMark single-thread, 8.1% advantage in PassMark single-thread, and wins in 2-thread and 4-thread tests indicate it handles everyday responsiveness and lightly threaded tasks well. The 6800H also wins floating point math and integer math, suggesting an edge in certain scientific and financial workloads.

The 5700X3D's single-core Cinebench results are the anomaly. A 51.2% lead in R23 single-core and 23.7% in R15 single-core cannot be explained by architecture alone, given the 6800H's higher boost clock. This may reflect platform-level differences in memory latency or boost behavior under test conditions. Regardless, the recorded data shows the 5700X3D ahead in those specific tests.

For mobile users, the 6800H is the only viable option, as the 5700X3D is a desktop part. The 6800H's 45 W TDP and integrated Radeon 680M graphics make it suitable for laptops and compact systems. The 5700X3D's 105 W TDP and lack of integrated graphics require a desktop platform with a discrete GPU.

For desktop builders prioritizing raw multi-threaded performance, the 5700X3D is the superior choice based on the benchmark data. Its 96 MB L3 cache and higher sustained power envelope deliver consistently better results in threaded workloads. The 6800H remains competitive in light-thread tasks but falls significantly behind in heavy compute scenarios.
