The Verdict

The data paints a clear split between these two GPUs. The AMD Radeon RX 9070 GRE is a desktop part with a higher average benchmark score (57,367 vs 43,667), meaning it sits above the RTX 4090 Mobile in overall database ranking by roughly 13,700 points. The RX 9070 GRE also holds a higher percentile position, 87th versus 84th, indicating it outperforms a larger share of the GPU population in aggregate metrics.

However, the RTX 4090 Mobile demonstrates a decisive single-test advantage in compute workloads. Its Geekbench OpenCL score of 180,831 is 39.6% higher than the RX 9070 GRE's 109,309. This is not a marginal gap; it is a substantial margin that matters for users whose workloads rely heavily on OpenCL compute. The mobile NVIDIA part also offers 16 GB of memory versus 12 GB, a 4 GB difference that could influence large dataset handling.

For a desktop builder seeking the stronger all-around database performer, the RX 9070 GRE is the choice. Its higher average score and percentile rank indicate better overall consistency across a wide range of tests. For a laptop user or someone prioritizing raw OpenCL compute throughput, the RTX 4090 Mobile is clearly superior in that specific domain, despite its lower aggregate average. The RTX 4090 Mobile also draws less power (120 W versus 220 W) and requires no external power connectors, making it suitable for integrated laptop designs.

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL. Here, the NVIDIA GeForce RTX 4090 Mobile wins decisively with a score of 180,831 against the AMD Radeon RX 9070 GRE's 109,309. The delta is 39.6% in NVIDIA's favor, marking this as a significant victory for the mobile part in compute-heavy scenarios.

Beyond this single head-to-head test, the broader benchmark records show different strengths. The RX 9070 GRE delivers 3DMark Steel Nomad DX12 performance at 5,424 points, a test the RTX 4090 Mobile does not appear in. The RTX 4090 Mobile also posts results in several Passmark tests, including 27,212 in G3D and 12,347 in GPU Compute, along with a Geekbench Vulkan score of 170,774; none of these tests have a corresponding entry for the RX 9070 GRE.

The average benchmark score gap is also telling. The RX 9070 GRE averages 57,367, which is 13,700 points higher than the RTX 4090 Mobile's 43,667. This represents a 31.4% advantage for AMD in the aggregate. The RX 9070 GRE's nearest rivals include the Intel Arc A580 (57,756, 0.7% higher) and the AMD Radeon RX 6950 XT (58,392, 1.8% higher), while the RTX 4090 Mobile sits near the NVIDIA Quadro M6000 (43,301, 0.8% lower) and the NVIDIA GeForce RTX 5050 Mobile (43,268, 0.9% lower).

The percentile ranking reinforces this split. At the 87th percentile, the RX 9070 GRE outperforms 87% of all GPUs in the database, while the RTX 4090 Mobile sits at the 84th percentile. This three-point gap in percentile terms is consistent with the average score difference. The single OpenCL test, however, shows that the RTX 4090 Mobile can dramatically outperform the RX 9070 GRE in the right workload, which is a useful reminder that aggregate scores can obscure large per-test swings.

Specification Differences

Memory configuration differs substantially. The RX 9070 GRE has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The RTX 4090 Mobile has 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. That is 4 GB more memory and 144.0 GB/s more bandwidth for NVIDIA.

Clock speeds vary by design. The RX 9070 GRE has a base clock of 1420 MHz, a boost clock of 2790 MHz, and a game clock of 2220 MHz. The RTX 4090 Mobile has a base clock of 1335 MHz and a boost clock of 1695 MHz, with no game clock listed. Memory clocks are identical at 2250 MHz with 18 Gbps effective, but the wider bus gives NVIDIA the bandwidth edge.

Power requirements are very different. The RX 9070 GRE is rated at 220 W TDP and requires dual-slot cooling with two 8-pin power connectors plus a 550 W suggested PSU. The RTX 4090 Mobile is rated at 120 W TDP, uses an IGP form factor, and requires no external power connectors. The desktop card is physically larger and more power-hungry, while the mobile part is designed for integration.

Interface and outputs also differ. The RX 9070 GRE uses PCIe 5.0 x16 and offers 1x HDMI 2.1b plus 3x DisplayPort 2.1a outputs. The RTX 4090 Mobile uses PCIe 4.0 x16, and its display outputs are described as portable device dependent.

Shading resources diverge sharply. The RX 9070 GRE has 3,072 shading units, 192 texture mapping units, and 96 ROPs. The RTX 4090 Mobile has 9,728 shading units, 304 TMUs, and 112 ROPs. Despite far fewer shading units, the RX 9070 GRE achieves a higher pixel rate (267.8 GPixel/s versus 189.8 GPixel/s) and a higher texture rate (535.7 GTexel/s versus 515.3 GTexel/s), driven by its much higher boost clock.

The RX 9070 GRE has a launch MSRP of 549 USD. The RTX 4090 Mobile has no recorded launch MSRP.

Architecture Differences

The RX 9070 GRE is built on RDNA 4.0 architecture using the Navi 48 chip, part of the Navi IV (RX 9000) generation. It is manufactured on a 4 nm process at TSMC with 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million transistors per square millimeter. Its predecessor is Navi III.

The RTX 4090 Mobile uses Ada Lovelace architecture with the AD103 chip, part of the GeForce 40 Mobile generation. It is manufactured on a 5 nm process at TSMC with 45,900 million transistors on a 379 mm² die, giving a density of 121.1 million transistors per square millimeter. Its predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile.

Ray tracing resources differ. The RX 9070 GRE has 48 ray tracing cores, while the RTX 4090 Mobile has 76. The NVIDIA part also includes 304 tensor cores, while the RX 9070 GRE lists no tensor core count. This reflects architectural priorities: NVIDIA's Ada Lovelace emphasizes AI-accelerated workloads with dedicated tensor hardware, while AMD's RDNA 4.0 focuses on traditional compute and ray tracing without a tensor core array.

Compute throughput is close despite these differences. The RX 9070 GRE delivers 34.28 TFLOPS of FP32 and FP16 (1:1), while the RTX 4090 Mobile delivers 32.98 TFLOPS in both. AMD edges ahead by 1.30 TFLOPS, a 3.9% margin, despite having only about one-third the shading units. This is possible because of the RX 9070 GRE's 2790 MHz boost clock versus the RTX 4090 Mobile's 1695 MHz boost clock.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The process node difference, 4 nm versus 5 nm, gives AMD a density advantage, but NVIDIA compensates with a slightly larger die and a much higher transistor count allocated to its tensor and RT cores. The transistor density figures, 151.0M per mm² versus 121.1M per mm², quantify the manufacturing advantage of AMD's smaller node.
