AMD Radeon RX 560X vs NVIDIA GeForce RTX 3070 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between these two mobile graphics solutions. In the two recorded head-to-head tests, the NVIDIA GeForce RTX 3070 Mobile wins both, and by substantial margins.

Starting with Geekbench OpenCL, the RTX 3070 Mobile scores 92,939 points against the RX 560X's 17,020 points. That is a 446.1% advantage for the NVIDIA part. This is not a close contest; the RTX 3070 Mobile delivers more than five times the raw compute throughput in this workload. For context, the RX 560X's average benchmark score of 18,626 places it near the AMD Radeon Pro 5700 XT (18,685, a 0.3% difference) and the NVIDIA Tesla K80 (18,866, a 1.3% difference). The RTX 3070 Mobile's average of 20,534 sits just 0.1% below the Intel Arc B570 (20,556) and 0.2% below the Intel Arc A750 (20,582), showing it competes with a much higher tier of hardware.

In Geekbench Vulkan, the story repeats. The RTX 3070 Mobile posts 86,768 points versus 20,231 for the RX 560X, a 328.9% delta. Vulkan is often considered a more efficient API for AMD hardware, but the data does not support that here. The RTX 3070 Mobile's architecture simply outclasses the older Polaris design in this test.

The overall record is 2 wins for NVIDIA, 0 for AMD. There are no benchmark tests where the RX 560X comes out ahead. The closest the RX 560X gets in any recorded metric is its percentile ranking: 62nd percentile among all GPUs, versus 65th for the RTX 3070 Mobile. That 3-percentile gap is modest, but the raw score differences are enormous. The RTX 3070 Mobile also has a higher average benchmark score (20,534 vs 18,626), which is roughly a 10% gap in aggregate performance.

Architecture Differences

The two GPUs come from different eras and design philosophies. The RTX 3070 Mobile uses the GA104 chip built on Ampere architecture, fabricated on Samsung's 8 nm process. It integrates 17,400 million transistors on a 392 mm² die, yielding a transistor density of 44.4 million per square millimeter. The RX 560X uses the Polaris 21 chip with GCN 4.0 architecture, built on GlobalFoundries' 14 nm process. It has 3,000 million transistors on a 123 mm² die, a density of 24.4 million per square millimeter. The RTX 3070 Mobile has nearly six times the transistor count and roughly three times the die area.

Core configuration differs sharply. The RTX 3070 Mobile has 5,120 shading units, 160 texture mapping units, and 80 ROPs. It also includes 40 dedicated ray tracing cores and 160 tensor cores, features absent from the RX 560X entirely. The RX 560X has 1,024 shading units, 64 TMUs, and 16 ROPs. Pixel rate tells the story: 124.8 GPixel/s for the RTX 3070 Mobile versus 20.40 GPixel/s for the RX 560X. Texture rate is 249.6 GTexel/s versus 81.60 GTexel/s. FP32 compute is 15.97 TFLOPS versus 2.611 TFLOPS, a six-fold difference.

Memory subsystems are also generations apart. The RTX 3070 Mobile uses 8 GB of GDDR6 on a 256-bit bus, with memory clocked at 1750 MHz (14 Gbps effective) for 448.0 GB/s of bandwidth. The RX 560X has 4 GB of GDDR5 on a 128-bit bus, also at 1750 MHz but only 7 Gbps effective, yielding 112.0 GB/s. That is a four-fold bandwidth advantage for NVIDIA.

API support differs. The RTX 3070 Mobile supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The RX 560X supports DirectX 12 (12_0), Vulkan 1.3, and OpenGL 4.6. The RTX 3070 Mobile also uses PCIe 4.0 x16, while the RX 560X uses PCIe 3.0 x8. Power draw is 115 W for the RTX 3070 Mobile versus 75 W for the RX 560X. Neither uses a power connector, but the RX 560X lists a suggested PSU of 250 W.

Where Each One Wins

Given the data, the RTX 3070 Mobile wins in every recorded category. There is no benchmark where the RX 560X takes the lead. The only area where the RX 560X is not dramatically behind is in the percentile ranking, where it sits at 62nd versus 65th for the RTX 3070 Mobile. That suggests the RX 560X is still a competent card for its era, but it is not competitive with the newer part.

The RTX 3070 Mobile is the clear choice for any workload that stresses compute or graphics throughput. Its 446.1% lead in OpenCL and 328.9% lead in Vulkan mean it will handle demanding applications, modern game engines, and compute tasks with far more headroom. The ray tracing cores and tensor cores add capabilities the RX 560X simply does not have, which matters for games or applications that use those features.

The RX 560X, by contrast, shows its age. Its 2.611 TFLOPS FP32 performance and 112 GB/s bandwidth are sufficient for older titles, light workloads, or 1080p gaming at modest settings, but the data does not support it for anything more demanding. Its 75 W TDP and lack of power connectors make it an easy drop-in for systems with limited power delivery, but that is a practical consideration, not a performance one.

For users who prioritize portability or low power draw, the RX 560X may have a niche. But in terms of raw performance, the RTX 3070 Mobile is ahead in every measured test, often by multiples. The RX 560X's 4 GB VRAM and 128-bit bus limit its ability to handle large textures or high resolutions, while the RTX 3070 Mobile's 8 GB and 256-bit bus provide a much larger working set.

The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 3070 Mobile outperforms the AMD Radeon RX 560X in every benchmark recorded. The OpenCL delta of 446.1% and Vulkan delta of 328.9% are not marginal improvements; they represent a generational leap. If the choice is between these two for a new build or upgrade, the RTX 3070 Mobile is the superior option in every performance metric.

The RTX 3070 Mobile is the pick for anyone who needs serious gaming performance, compute capability, or future-proofing. Its 15.97 TFLOPS FP32, 40 ray tracing cores, and 160 tensor cores place it in a different class. Its average benchmark score of 20,534 puts it within 0.1% of the Intel Arc B570 and 0.2% of the Intel Arc A750, while the RX 560X's 18,626 average sits near the AMD Radeon Pro 5700 XT and NVIDIA RTX 2070. That means the RTX 3070 Mobile competes with newer midrange parts, while the RX 560X is closer to older high-end parts from several generations ago.

The RX 560X should only be considered if the system's power budget is extremely tight (75 W TDP versus 115 W) or if the workload is so light that the performance gap does not matter. But even then, the 62nd percentile ranking shows it is not a weak card; it is just outclassed by the RTX 3070 Mobile. For any serious gaming, rendering, or compute task, the recorded data says to choose the RTX 3070 Mobile without hesitation.
