AMD Radeon RX 6700 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The AMD Radeon RX 6700 and NVIDIA GeForce RTX 5070 Mobile represent two very different approaches to graphics hardware: a desktop card from the RDNA 2 era and a modern laptop GPU built on Blackwell. Benchmark data shows a clear overall winner, but the AMD card retains specific advantages that matter for certain workloads. The RTX 5070 Mobile secures 7 of 9 head-to-head wins, yet the RX 6700 counters with a decisive victory in DirectX 9 and a smaller win in 2D tests. Average benchmark scores are nearly identical, with the RX 6700 at 30433 and the RTX 5070 Mobile at 29928, a difference of just 1.7% in the AMD card's favor.

Head-to-Head Benchmarks

The largest single-score gap in the comparison belongs to the NVIDIA GeForce RTX 5070 Mobile in the Geekbench Vulkan test. The RTX 5070 Mobile scores 116960 against the RX 6700's 83974, a 28.2% advantage. This is a substantial margin that indicates the Blackwell architecture's compute efficiency in the Vulkan API is far ahead of the older RDNA 2 design. The OpenCL result follows a similar pattern, with the RTX 5070 Mobile posting 122238 versus 97841 for the RX 6700, a 20% lead. These two compute-oriented benchmarks are the strongest evidence of the RTX 5070 Mobile's modern execution capabilities.

In DirectX-focused PassMark tests, the RTX 5070 Mobile continues its dominance. PassMark DirectX 12 shows the NVIDIA part at 93 versus 71 for the AMD card, a 23.7% delta. DirectX 11 results are closer but still favor NVIDIA, with scores of 192 and 166 respectively, representing a 13.5% gap. The DirectX 10 test shows a narrower 10.9% difference, with the RTX 5070 Mobile at 129 and the RX 6700 at 115. The overall PassMark G3D score, which aggregates 3D rendering performance, lands at 20355 for the RTX 5070 Mobile against 18931 for the RX 6700, a 7% win for NVIDIA.

The AMD Radeon RX 6700 finds its biggest win in the PassMark DirectX 9 test. Here it scores 250 versus 214 for the RTX 5070 Mobile, a 16.8% advantage. This is notable because DirectX 9 remains relevant for older titles and certain emulation workloads. The RX 6700 also wins the PassMark G2D test, scoring 936 against 896, a 4.5% margin. The final benchmark, PassMark GPU Compute, is essentially a tie: the RTX 5070 Mobile scores 8279 against the RX 6700's 8240, a 0.5% difference that falls within noise. Overall, the RTX 5070 Mobile wins 7 of the 9 direct comparisons, but the RX 6700's two wins are in areas where NVIDIA cannot match its legacy DirectX performance.

Where Each One Wins

The RTX 5070 Mobile is the clear choice for modern API workloads. Its Vulkan score of 116960 is not just a win; it is a 28.2% improvement over the RX 6700, suggesting that games and applications built around Vulkan will see significant performance gains. The OpenCL result reinforces this, with a 20% lead that benefits compute-heavy tasks like video encoding or physics simulations that use OpenCL. In DirectX 12, the 23.7% margin means the RTX 5070 Mobile is better suited for current-generation game titles that have moved past DX11. The PassMark G3D result, while a smaller 7% win, still indicates that the NVIDIA part holds the edge in overall rasterized 3D performance.

The RX 6700 wins in two specific niches. The PassMark DirectX 9 score of 250 versus 214 is a 16.8% advantage that matters for older games, particularly those running on engines that were optimized for DX9. This is not a trivial concern for players with large back catalogs of classic titles. The G2D win, 936 versus 896, suggests the AMD card handles 2D rendering tasks like desktop compositing and image processing slightly faster. For users who run legacy software or prioritize 2D application responsiveness, the RX 6700 has a measurable edge. However, these wins are narrow in scope and do not compensate for the RTX 5070 Mobile's overwhelming lead in modern compute and DirectX workloads.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The AMD Radeon RX 6700 uses the RDNA 2.0 architecture on a 7 nm TSMC process, while the NVIDIA GeForce RTX 5070 Mobile uses the Blackwell 2.0 architecture on a 5 nm TSMC process. The transistor counts reflect this generational leap: the RX 6700 packs 17,200 million transistors on a 335 mm² die, while the RTX 5070 Mobile fits 21,900 million transistors on a much smaller 181 mm² die. This results in a transistor density of 51.3M per mm² for AMD versus 121.0M per mm² for NVIDIA, showing the Blackwell design is far more compact.

The compute configurations differ significantly. The RX 6700 has 2304 shading units, while the RTX 5070 Mobile has 4608 shading units, exactly double. Both have 144 texture mapping units, but the AMD card has 64 ROPs versus 48 for NVIDIA. Ray tracing cores are equal at 36 each, but the RTX 5070 Mobile adds 144 tensor cores, which the RX 6700 lacks entirely. The FP32 performance favors NVIDIA, with 13.13 TFLOPS versus 11.29 TFLOPS, a 16% advantage. FP16 performance is more complex: the RX 6700 achieves 22.58 TFLOPS using a 2:1 ratio, while the RTX 5070 Mobile stays at 13.13 TFLOPS with a 1:1 ratio, meaning AMD can process half-precision data faster when the workload supports it.

Memory architecture is another major divergence. The RX 6700 uses 10 GB of GDDR6 on a 160-bit bus with 320.0 GB/s bandwidth, while the RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth. Despite having 2 GB less memory, the NVIDIA part delivers 20% more bandwidth due to the faster GDDR7 standard. The RX 6700's clocks are significantly higher, with a base of 1941 MHz and boost of 2450 MHz, compared to the RTX 5070 Mobile's 907 MHz base and 1425 MHz boost. However, the Blackwell architecture's efficiency makes the lower clocks irrelevant in most benchmarks.

Specification Differences

The most striking specification difference is power consumption. The RX 6700 has a TDP of 175 W and requires a dual-slot cooler with a 1x 8-pin power connector and a 450 W suggested PSU. The RTX 5070 Mobile is an IGP (integrated graphics processor) with a 50 W TDP, no power connectors, and no suggested PSU. This is a 125 W difference, making the NVIDIA part dramatically more power-efficient. The RX 6700 is a physical card measuring 267 mm in length, 110 mm in height, and 40 mm in width, while the RTX 5070 Mobile has no listed dimensions because it is soldered onto a motherboard.

The bus interface differs, with the RX 6700 using PCIe 4.0 x16 and the RTX 5070 Mobile using PCIe 5.0 x16. Display outputs also diverge: the RX 6700 has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the RTX 5070 Mobile's outputs are listed as "Portable Device Dependent," meaning they vary by laptop design. The memory clocks show the GDDR7 advantage, with the RTX 5070 Mobile running at 1500 MHz with 24 Gbps effective speed, while the RX 6700 runs at 2000 MHz with 16 Gbps effective speed. Release dates are far apart: the RX 6700 launched on 2021-06-08 and is end-of-life, while the RTX 5070 Mobile launched on 2025-04-14 and is active. The RX 6700's predecessor is Navi and its successor is Navi III, while the RTX 5070 Mobile's predecessor is GeForce 40 Mobile.

The Verdict

The benchmark data is unambiguous for modern workloads: the NVIDIA GeForce RTX 5070 Mobile is the superior GPU for current and future gaming. Its 28.2% lead in Vulkan and 23.7% lead in DirectX 12 are decisive margins that will translate to better frame rates in contemporary titles. The 20% OpenCL advantage and 7% G3D win further cement its position as the more capable all-around performer. The RTX 5070 Mobile also achieves this with a 50 W TDP versus 175 W, making it dramatically more efficient for laptop use.

The AMD Radeon RX 6700 is not without merit, but its wins are confined to legacy scenarios. The 16.8% DirectX 9 advantage makes it a better choice for players who prioritize older games or run software that relies on DX9. The 4.5% G2D win is a minor bonus for 2D-heavy tasks. However, these two wins out of nine benchmarks do not offset the RTX 5070 Mobile's dominance in every modern API. For anyone building a new system or buying a laptop, the RTX 5070 Mobile is the data-driven choice. The RX 6700 is only recommended for users with a specific need for legacy DirectX 9 performance, where it holds a meaningful and measurable edge.
