AMD Radeon RX 6700 vs AMD Radeon RX 6800M Comparison

The AMD Radeon RX 6700 and the AMD Radeon RX 6800M both rely on the same Navi 22 chip and RDNA 2.0 architecture, yet they are positioned for entirely different environments: one is a desktop card, the other a mobile IGP. The benchmark data reveals a clear split, with the desktop RX 6700 winning 9 of 11 head-to-head comparisons, while the mobile RX 6800M takes the remaining 2. Despite the RX 6800M’s higher raw compute specifications, the RX 6700 consistently delivers superior scores in most legacy and compute-oriented tests, though the RX 6800M shows its strength in modern 3DMark and Vulkan workloads.

Head-to-Head Benchmarks

The most lopsided victory for the AMD Radeon RX 6700 comes in the Passmark DirectX 9 test, where it scores 250 against the RX 6800M’s 147 — a 70.1% advantage. This is not an isolated outlier; the RX 6700 also dominates in Passmark G2D (936 vs 538, a 74% lead) and Passmark GPU Compute (8240 vs 5032, a 63.8% delta). The data suggests the desktop card’s higher base clock of 1941 MHz, compared to the RX 6800M’s 2116 MHz, does not translate into an advantage for the mobile part in these older APIs. Instead, the RX 6700’s Passmark G3D score of 18931 versus 13261 (42.8% ahead) indicates a substantial overall rasterization performance gap.

The RX 6700 also wins decisively in DirectX 11, posting 166 points versus 127 — a 30.7% edge. Even in DirectX 12, where the RX 6800M is built on the same architecture, the RX 6700 leads by 9.2% (71 vs 65). Geekbench results follow a similar pattern: the RX 6700 wins OpenCL with 97841 over 87621 (11.7% ahead) and Metal with 122223 over 113721 (7.5% ahead). The only Passmark loss for the RX 6700 is in DirectX 10, where it still wins 115 vs 101 (13.9% ahead), meaning the RX 6800M’s only Passmark win is none — the mobile part loses every single Passmark subtest.

The RX 6800M’s two victories are concentrated in modern, cross-platform workloads. In 3DMark Steel Nomad DX12, it scores 2238 against the RX 6700’s 2014, a 10% advantage. More notably, in Geekbench Vulkan, the RX 6800M scores 94766 versus 83974 — an 11.4% lead. These wins align with its higher shading unit count (2560 vs 2304) and ray tracing core count (40 vs 36), suggesting that when the workload scales with compute units and uses modern APIs, the mobile chip’s extra hardware matters. However, these two wins are not enough to offset the RX 6700’s dominance in the other nine tests, where the average delta is roughly 30-40% in favor of the desktop card.

Where Each One Wins

The AMD Radeon RX 6700 is the clear choice for anyone prioritizing legacy DirectX performance and general-purpose compute. Its Passmark DirectX 9 score of 250 is 70.1% higher than the RX 6800M, and it also wins DirectX 10 (13.9%), DirectX 11 (30.7%), and DirectX 12 (9.2%). For users running older games or applications that rely on these APIs, the RX 6700 provides a significantly smoother experience. The RX 6700 also dominates in 2D workloads (Passmark G2D 936 vs 538) and GPU compute (8240 vs 5032), making it more suitable for productivity tasks that leverage OpenCL or Metal. Its Geekbench OpenCL score of 97841 is 11.7% higher, and its Metal score of 122223 is 7.5% higher, reinforcing its strength in compute-heavy environments.

The AMD Radeon RX 6800M wins specifically in modern, cross-platform 3D workloads. Its 3DMark Steel Nomad DX12 score of 2238 is 10% higher, and its Geekbench Vulkan score of 94766 is 11.4% higher. These are the benchmarks that stress newer rendering pipelines and ray tracing features. With 40 ray tracing cores versus the RX 6700’s 36, the RX 6800M has a theoretical advantage in RT-heavy games. However, its Passmark G3D score of 13261 is 42.8% lower, so the win is not universal. The RX 6800M’s higher memory bandwidth (384.0 GB/s vs 320.0 GB/s) and larger memory pool (12 GB vs 10 GB) may also help in texture-heavy scenes, but the data shows this advantage only materializes in the two specific tests it wins.

Specification Differences

The most obvious difference is form factor: the RX 6700 is a dual-slot desktop card with a 1x 8-pin power connector, while the RX 6800M is an IGP (integrated graphics processor) with no power connectors and dimensions listed as portable-device dependent. The RX 6700 has a TDP of 175 W, whereas the RX 6800M draws 145 W. Memory configurations differ as well: the RX 6700 has 10 GB of GDDR6 on a 160-bit bus, yielding 320.0 GB/s, while the RX 6800M has 12 GB on a 192-bit bus, yielding 384.0 GB/s. Both use the same 7 nm process and 17,200 million transistors on a 335 mm² die.

Core counts differ, with the RX 6800M having 2560 shading units and 160 TMUs, compared to the RX 6700’s 2304 shading units and 144 TMUs. The RX 6800M also has more ray tracing cores (40 vs 36). Clock speeds are mixed: the RX 6800M has a higher base clock (2116 MHz vs 1941 MHz) and game clock (2300 MHz vs 2174 MHz), but the RX 6700 has a higher boost clock (2450 MHz vs 2390 MHz). Both share the same 64 ROPs, PCIe 4.0 x16 interface, and display outputs differ (the RX 6700 has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RX 6800M’s outputs are portable-device dependent). The RX 6700 lists a suggested PSU of 450 W, while the RX 6800M has none.

Architecture Differences

Both GPUs are built on TSMC’s 7 nm process and use the RDNA 2.0 architecture, with the same Navi 22 chip and identical transistor counts and die size. The fundamental architectural features — DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 — are identical. The difference lies in how the silicon is configured and deployed. The RX 6800M is part of the Navi Mobile generation, while the RX 6700 is from the Navi II desktop generation. The RX 6800M enables more of the chip’s potential: 2560 shading units enabled versus 2304, and 40 RT cores versus 36. This suggests the RX 6700 is a cut-down version of the same die, with fewer active compute units.

The RX 6800M’s higher base and game clocks (2116 MHz and 2300 MHz) allow it to reach a higher FP32 throughput of 12.24 TFLOPS, compared to the RX 6700’s 11.29 TFLOPS. The mobile part also has a higher texture rate (382.4 GTexel/s vs 352.8 GTexel/s), but a slightly lower pixel rate (153.0 GPixel/s vs 156.8 GPixel/s). The RX 6800M’s 12 GB memory configuration is larger, but the RX 6700 has a higher boost clock that may compensate in some scenarios. Both are end-of-life products, with the RX 6700 released on 2021-06-08 and the RX 6800M on 2021-05-30. The RX 6700’s predecessor is Navi, while the RX 6800M’s predecessor is Polaris Mobile.

The Verdict

The data clearly favors the AMD Radeon RX 6700 for desktop users who need consistent performance across a wide range of benchmarks. With 9 wins out of 11 and an average score of 30433 versus 28874, the RX 6700 is the more reliable performer in this comparison. Its 70.1% lead in DirectX 9 and 74% lead in G2D make it the better option for older games and 2D applications, while its 42.8% advantage in Passmark G3D shows it handles standard 3D workloads more effectively. The RX 6700’s higher boost clock (2450 MHz) may explain why it outperforms the RX 6800M despite having fewer shading units and a lower base clock.

The AMD Radeon RX 6800M should be chosen by users who specifically need modern API performance in a mobile form factor. Its wins in 3DMark Steel Nomad DX12 (10% ahead) and Geekbench Vulkan (11.4% ahead) indicate it is better suited for current-generation games that use these APIs, and its 145 W TDP makes it more power-efficient than the RX 6700’s 175 W. The RX 6800M’s 12 GB memory and 384.0 GB/s bandwidth provide a larger memory pool, which could be an advantage in future titles. However, its overall benchmark profile is weaker — it loses all Passmark tests and trails in Geekbench Metal and OpenCL. The verdict is straightforward: the RX 6700 wins on raw performance across the board, while the RX 6800M is a niche pick for Vulkan-centric workloads in a laptop.
