NVIDIA GeForce RTX 5070 Mobile 12 GB vs NVIDIA Switch 2 GPU Comparison

Head-to-Head Benchmarks

The recorded data contains no comparative benchmark scores between the NVIDIA GeForce RTX 5070 Mobile 12 GB and the NVIDIA Switch 2 GPU. Both entries list empty benchmark arrays, zero recorded wins for each side, and an average benchmark score of zero. The nearest rival fields are also empty, meaning the database has no direct performance measurements, percentile comparisons, or delta percentages to draw upon for this matchup.

What the data does provide is raw compute throughput figures that can be contrasted directly. The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 performance, while the Switch 2 GPU reaches 4.301 TFLOPS. That places the mobile part at roughly three times the single-precision throughput of the console GPU. In FP16 workloads, the RTX 5070 Mobile maintains 13.13 TFLOPS with a 1:1 ratio, while the Switch 2 GPU posts 8.602 TFLOPS using a 2:1 ratio. The console part doubles its FP16 rate relative to FP32, but the absolute FP16 advantage still belongs to the RTX 5070 Mobile by a margin of approximately 4.5 TFLOPS.

Pixel throughput tells a similar story. The RTX 5070 Mobile renders 68.40 GPixel/s, compared to 22.40 GPixel/s for the Switch 2 GPU. Texture fill rates stand at 205.2 GTexel/s versus 67.20 GTexel/s. Both products occupy the 50th percentile in the database's all-GPU ranking, though this percentile is based on the aggregate GPU population rather than head-to-head testing. Without actual benchmark scores, the percentile values do not differentiate the two parts.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The RTX 5070 Mobile uses the GB206 chip built on Blackwell 2.0 architecture, fabricated at TSMC on a 5 nm process. The Switch 2 GPU relies on the GA10B chip with Ampere architecture, produced at Samsung on an 8 nm node. The process gap is substantial: 5 nm versus 8 nm translates into different transistor densities and power characteristics, though the database does not list the Switch 2 GPU's transistor count or density.

Die sizes are comparable in physical terms. The RTX 5070 Mobile measures 181 mm², while the Switch 2 GPU is larger at 200 mm². The RTX 5070 Mobile integrates 21,900 million transistors, giving it a density of 121.0 million transistors per square millimeter. The Switch 2 GPU's transistor count is listed as unknown, so no density figure can be calculated.

Core configurations diverge sharply. The RTX 5070 Mobile contains 4608 shading units, 144 texture mapping units, 48 raster operations units, 36 ray tracing cores, and 144 tensor cores. The Switch 2 GPU has 1536 shading units, 48 TMUs, 16 ROPs, 12 RT cores, and 48 tensor cores. The mobile part offers triple the shader count, triple the TMUs, triple the ROPs, triple the RT cores, and triple the tensor cores. Clock speeds differ as well: the RTX 5070 Mobile runs at a 907 MHz base and 1425 MHz boost, while the Switch 2 GPU operates at 561 MHz base and 1400 MHz boost. The boost clocks are close, but the base clock gap is significant.

Memory architecture is another major divergence. The RTX 5070 Mobile uses 12 GB of GDDR7 on a 192-bit bus, producing 576.0 GB/s of bandwidth. The Switch 2 GPU uses 12 GB of LPDDR5X on a 128-bit bus, yielding 102.4 GB/s. Both have the same capacity, but the bandwidth difference is roughly 5.6 times in favor of the mobile part. Memory clocks also differ: 1500 MHz with 24 Gbps effective for the RTX 5070 Mobile, versus 800 MHz with 6.4 Gbps effective for the Switch 2 GPU.

Power targets are close but not identical. The RTX 5070 Mobile carries a 50 W TDP, while the Switch 2 GPU is rated at 40 W. The RTX 5070 Mobile is classified as an integrated graphics product with no power connectors, while the Switch 2 GPU's slot width, power connectors, and power supply requirements are not specified.

The Verdict

The database clearly separates these two products by capability class. The RTX 5070 Mobile delivers roughly three times the FP32 throughput, three times the shader count, and more than five times the memory bandwidth of the Switch 2 GPU. It also uses a newer architecture on a smaller process node. The Switch 2 GPU counters with a lower power draw and a larger die, but none of its recorded specifications close the compute gap.

The RTX 5070 Mobile is the appropriate selection for workloads that demand raw graphics throughput, high-bandwidth memory access, and modern architecture features. Its 50 W TDP and integrated form factor indicate a laptop-class part designed for portable performance. The Switch 2 GPU is a console part with a 40 W TDP, intended for a fixed hardware environment where power efficiency matters and where the 12 GB LPDDR5X pool provides capacity without the bandwidth demands of high-end PC gaming.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical. The RTX 5070 Mobile connects via PCIe 5.0 x16, while the Switch 2 GPU has no listed bus interface. Display outputs are portable-device-dependent for the RTX 5070 Mobile, while the Switch 2 GPU lists no outputs, reflecting its integration into a handheld console system.

The RTX 5070 Mobile is the stronger part on every measured compute metric. The Switch 2 GPU is the lower-power alternative with equal memory capacity but far less bandwidth and throughput.

Where Each One Wins

The RTX 5070 Mobile wins in every recorded computational category. FP32 performance is 13.13 TFLOPS versus 4.301 TFLOPS. FP16 performance is 13.13 TFLOPS versus 8.602 TFLOPS. Pixel fill rate is 68.40 GPixel/s versus 22.40 GPixel/s. Texture fill rate is 205.2 GTexel/s versus 67.20 GTexel/s. The memory bandwidth advantage is decisive at 576.0 GB/s versus 102.4 GB/s. The RT core count is 36 versus 12, and the tensor core count is 144 versus 48. The RTX 5070 Mobile also uses the newer Blackwell 2.0 architecture on a smaller 5 nm node.

The Switch 2 GPU wins in power efficiency per absolute terms: 40 W TDP versus 50 W TDP. It also has a larger die at 200 mm² versus 181 mm², though this is not a performance advantage. The Switch 2 GPU's FP16 throughput of 8.602 TFLOPS is higher than its FP32 figure due to the 2:1 ratio, giving it a relative FP16 efficiency edge over the RTX 5070 Mobile's 1:1 ratio, but the absolute FP16 number still trails.

For use-case segmentation, the RTX 5070 Mobile suits high-performance mobile computing, where its 12 GB GDDR7 pool and 576.0 GB/s bandwidth can feed demanding workloads. The Switch 2 GPU fits a fixed console environment, where its 12 GB LPDDR5X capacity at 102.4 GB/s is sufficient for optimized titles and its 40 W TDP supports portable operation. The RTX 5070 Mobile targets PC gaming and compute tasks; the Switch 2 GPU targets the Nintendo console ecosystem.
