AMD Radeon RX 7900 GRE vs NVIDIA GeForce RTX 5070 Mobile Comparison

The benchmark data presents a decisive matchup: the AMD Radeon RX 7900 GRE is the overwhelmingly faster GPU, winning 8 of the 9 head-to-head tests. The NVIDIA GeForce RTX 5070 Mobile manages only a single, albeit significant, victory. This is not a close contest; it is a demonstration of the performance gulf between a high-end desktop card and a mobile part.

Head-to-Head Benchmarks

The Radeon RX 7900 GRE's dominance is most pronounced in compute-heavy workloads. In the Passmark GPU Compute test, it scores 15,016 against the RTX 5070 Mobile's 8,279, a massive 44.9% advantage. This is the largest delta in the entire comparison and points to a fundamental difference in raw processing power. The gap is similarly vast in DirectX 11, where the AMD card scores 300 versus 192, a 36% lead, and in DirectX 9, where it wins 310 to 214 (31% ahead).

The pattern continues across the rest of the DirectX suite. In DirectX 12, the RX 7900 GRE leads with a score of 107 compared to 93, a 13.1% advantage. The older DirectX 10 API shows a narrower margin, with the AMD card winning 139 to 129 (7.2% ahead). Even in the 2D test, the AMD card is faster, scoring 1,180 versus 896, a 24.1% lead. The overall gaming performance metric, Passmark G3D, reflects this trend, with the RX 7900 GRE scoring 27,089 against 20,355, a 24.9% victory. The AMD card also wins the OpenCL compute test decisively, scoring 175,758 to the NVIDIA card's 122,238, a 30.5% advantage.

The sole bright spot for the NVIDIA GeForce RTX 5070 Mobile is in the Vulkan API. Here, it scores 116,960, which is 17.1% higher than the Radeon RX 7900 GRE's score of 99,850. This is a notable win, suggesting the NVIDIA architecture has a specific strength in this API that is not replicated elsewhere. It is the only test where the NVIDIA part demonstrates a clear performance advantage, and it is a substantial one.

The Verdict

The data is unambiguous. For any user prioritizing raw performance, the AMD Radeon RX 7900 GRE is the clear choice. Its wins in the majority of benchmarks, particularly the 44.9% lead in GPU compute and 24.9% lead in the G3D gaming metric, establish it as the superior performer for graphics-intensive tasks. The RTX 5070 Mobile's single victory in Vulkan is interesting but does not compensate for its losses elsewhere.

The choice comes down to the platform. The RX 7900 GRE is a dual-slot desktop card with a 260 W TDP and dual 8-pin power connectors, requiring a 600 W power supply. The RTX 5070 Mobile is an integrated graphics processor (IGP) with a 50 W TDP and no power connectors, designed for portable devices. The desktop card's performance is expected given its power envelope, but the data shows that even with that power, it is decisively faster.

Therefore, the verdict is clear: the AMD Radeon RX 7900 GRE is the right choice for a desktop system where performance is the sole objective. The NVIDIA GeForce RTX 5070 Mobile is the only option for a laptop or other portable device, and its Vulkan performance is a point in its favor for that specific use case. The data suggests no scenario where a user would choose the RTX 5070 Mobile for a desktop build if the RX 7900 GRE is available.

Specification Differences

The two GPUs differ in almost every core specification. The AMD Radeon RX 7900 GRE has more shading units (5,120 vs. 4,608), more texture mapping units (320 vs. 144), and far more render output units (160 vs. 48). It also has more ray tracing cores (80 vs. 36). The NVIDIA card has 144 tensor cores, while the AMD card has none listed.

Memory specifications also differ significantly. The RX 7900 GRE offers 16 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of bandwidth. The RTX 5070 Mobile has 8 GB of GDDR7 memory on a 128-bit bus, yielding 384.0 GB/s. Clock speeds are higher on the AMD card, with a 2,245 MHz boost clock compared to the NVIDIA card's 1,425 MHz. The AMD card's TDP is 260 W, while the NVIDIA card is rated at 50 W.

The physical and platform requirements are different. The RX 7900 GRE is a dual-slot card measuring 276 mm in length, while the RTX 5070 Mobile is an IGP. The desktop card uses PCIe 4.0 x16, while the mobile part uses PCIe 5.0 x16. The AMD card's display outputs are specified as 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, whereas the NVIDIA card's outputs are listed as "Portable Device Dependent."

Architecture Differences

The architectural divide is clear. The NVIDIA GeForce RTX 5070 Mobile is built on the Blackwell 2.0 architecture with the GB206 chip, while the AMD Radeon RX 7900 GRE uses the RDNA 3.0 architecture with the Navi 31 chip (codename "Plum Bonito"). Both are manufactured on a 5 nm process at TSMC, but the AMD chip is much larger.

The AMD chip has a die size of 529 mm² and houses 57,700 million transistors, resulting in a transistor density of 109.1M / mm². The NVIDIA chip is smaller at 181 mm² and contains 21,900 million transistors, for a density of 121.0M / mm². This means the NVIDIA chip is more densely packed despite having fewer total transistors.

The AMD card's RDNA 3.0 architecture delivers FP32 performance of 45.98 TFLOPS and FP16 performance of 91.96 TFLOPS (2:1 ratio). The NVIDIA card's Blackwell 2.0 architecture delivers 13.13 TFLOPS for both FP32 and FP16 (1:1 ratio). The AMD card also has a higher pixel rate (359.2 GPixel/s vs. 68.40 GPixel/s) and texture rate (718.4 GTexel/s vs. 205.2 GTexel/s). Both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The NVIDIA card is part of the GeForce 50-series, while the AMD card is from the Radeon RX 7000 series.

Where Each One Wins

The Radeon RX 7900 GRE is the victor in most scenarios. For any user building a desktop PC focused on high-resolution gaming, content creation, or compute tasks, the data shows it is the superior choice. Its wins in DirectX 11, DirectX 12, and the G3D gaming benchmark make it the better option for current and upcoming games. Its massive lead in GPU compute and OpenCL performance also makes it the better choice for rendering, video encoding, and other professional workloads that leverage these APIs.

The NVIDIA GeForce RTX 5070 Mobile's only win is in the Vulkan API, where it is 17.1% faster. This makes it the preferred choice for applications or games that are specifically optimized for Vulkan. However, the primary use case for this GPU is in laptops and other portable devices, as it is an IGP with a 50 W TDP. In that context, its Vulkan advantage is a notable feature, but its lower overall performance is a trade-off for its low power consumption and lack of external power requirements. For a portable system where Vulkan performance is critical, the RTX 5070 Mobile is the clear winner.
