AMD Radeon RX 7700 vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the two cards, with the AMD Radeon RX 7700 taking 5 of the 8 head-to-head benchmarks while the NVIDIA GeForce RTX 5070 Mobile wins 3. The largest margin in favor of the AMD card appears in PassMark G2D, where the RX 7700 scores 1206 against 896 for the RTX 5070 Mobile, a 34.6% advantage. The second-biggest AMD win is in PassMark GPU Compute, with 10963 versus 8279, a 32.4% lead. PassMark DirectX 9 also favors AMD by 22%, with scores of 261 and 214 respectively.

The NVIDIA card claims its largest win in PassMark DirectX 10, scoring 129 against 92, a 28.7% margin. Geekbench OpenCL goes to NVIDIA as well, 122238 versus 106028, a 13.3% difference. The narrowest NVIDIA win is PassMark DirectX 11, where 192 edges out 186, only 3.1% ahead.

The remaining benchmarks are close. PassMark DirectX 12 goes to AMD by 3.2% (96 versus 93), and PassMark G3D goes to AMD by 3% (20974 versus 20355). While the RTX 5070 Mobile leads in compute-oriented OpenCL and the older DirectX 10 path, the RX 7700 dominates in 2D performance, compute workloads, and legacy DirectX 9, while holding a slight edge in modern DirectX 12 and overall 3D rendering.

Where Each One Wins

The AMD Radeon RX 7700 delivers its strongest results in 2D graphics, GPU compute, and DirectX 9 workloads. The 34.6% lead in G2D indicates a substantial advantage in 2D rendering tasks, while the 32.4% margin in GPU compute suggests strong general-purpose throughput. The 22% DirectX 9 lead points to superior legacy API performance. In DirectX 12, the AMD card is ahead by 3.2%, and in G3D by 3%, meaning it also holds the edge in modern 3D rendering and the overall 3D composite score.

The NVIDIA GeForce RTX 5070 Mobile wins in Geekbench OpenCL, DirectX 10, and DirectX 11. The OpenCL score of 122238 is the highest single benchmark recorded for either card, and the 28.7% DirectX 10 margin is its largest. The DirectX 11 win is narrow, only 3.1%, which makes that category effectively a toss-up in the recorded data. The NVIDIA card also sits at the 75th percentile across all GPUs, versus the 58th percentile for the AMD card, reflecting its stronger aggregate standing in the database despite losing the direct head-to-head count.

Architecture Differences

The two cards use different architectures and chips. The AMD Radeon RX 7700 is built on RDNA 3.0 with the Navi 32 chip and carries the codename Wheat Nas, part of the Navi III (RX 7000) generation. The NVIDIA GeForce RTX 5070 Mobile uses Blackwell 2.0 with the GB206 chip and belongs to the GeForce 50 Mobile generation. Both are manufactured on a 5 nm process at TSMC, but the transistor counts differ: the AMD chip has 28,100 million transistors on a 346 mm² die, while the NVIDIA chip has 21,900 million transistors on a 181 mm² die. This results in a transistor density of 81.2M per mm² for AMD and 121.0M per mm² for NVIDIA, meaning the NVIDIA die packs transistors more tightly despite having fewer total transistors.

Ray tracing hardware is present on both, with 40 RT cores on the AMD card and 36 on the NVIDIA card. The NVIDIA card also includes 144 tensor cores, while the AMD card has none listed. Shading unit counts differ: 2560 for AMD versus 4608 for NVIDIA, yet the AMD card still achieves higher FP32 throughput at 25.18 TFLOPS versus 13.13 TFLOPS. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card uses a PCIe 4.0 x16 interface, while the NVIDIA card uses PCIe 5.0 x16.

Specification Differences

The most visible difference is memory configuration. The AMD Radeon RX 7700 has 16 GB of GDDR6 on a 256-bit bus with 624.1 GB/s bandwidth. The NVIDIA GeForce RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth. The AMD card offers double the capacity and roughly 62.5% more bandwidth. Clock behavior also differs: the AMD base clock is 1900 MHz with a boost of 2459 MHz and a game clock of 2041 MHz, while the NVIDIA base clock is 907 MHz with a boost of 1425 MHz and no game clock listed. Memory clocks are 2438 MHz (19.5 Gbps effective) for AMD and 1500 MHz (24 Gbps effective) for NVIDIA.

Pixel and texture rates favor AMD: 236.1 GPixel/s versus 68.40 GPixel/s, and 393.4 GTexel/s versus 205.2 GTexel/s. The AMD card has 160 texture mapping units and 96 ROPs, while the NVIDIA card has 144 TMUs and 48 ROPs. Power consumption differs significantly: the AMD card is rated at 200 W TDP and requires dual-slot cooling with 2x 8-pin power connectors and a 550 W suggested PSU, while the NVIDIA card is rated at 50 W TDP and is an IGP with no power connectors and no suggested PSU listed. The AMD card is a dual-slot discrete card measuring 267 mm in length, 135 mm in height, and 50 mm in width, with display outputs of 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The NVIDIA mobile chip has no listed dimensions and its display outputs are described as portable device dependent.

The AMD card was released on 2025-09-17, while the NVIDIA card was released on 2025-04-14. The AMD card lists its predecessor as Navi II and successor as Navi IV, while the NVIDIA card lists its predecessor as GeForce 40 Mobile and has no successor listed. Both are marked as active in production.

The Verdict

The benchmark data indicates that the AMD Radeon RX 7700 wins more head-to-head tests, taking 5 of 8, with decisive margins in G2D (34.6%), GPU compute (32.4%), and DirectX 9 (22%). It also holds smaller leads in DirectX 12 and G3D. Its 16 GB memory configuration and higher bandwidth make it the stronger option for workloads that depend on memory capacity and throughput.

The NVIDIA GeForce RTX 5070 Mobile, despite losing the head-to-head count, records a much higher average benchmark score of 29928 versus 15852 and a 75th percentile ranking. Its wins in OpenCL and DirectX 10, along with its tensor cores and far lower 50 W TDP, position it differently: it is a mobile chip with a compact footprint, no external power connectors, and a modern PCIe 5.0 interface. The AMD card, by contrast, is a 200 W dual-slot discrete card requiring 2x 8-pin connectors and a 550 W PSU.

For users prioritizing raw 2D performance, compute throughput, legacy API support, and memory capacity, the data favors the AMD Radeon RX 7700. For users who need a low-power mobile solution with tensor core support, higher aggregate percentile standing, and stronger OpenCL results, the NVIDIA GeForce RTX 5070 Mobile is the recorded choice. The narrow margins in DirectX 11, DirectX 12, and G3D suggest these cards are closely matched in modern gaming workloads, with the deciding factors coming down to memory size, power envelope, and form factor.
