NVIDIA GeForce RTX 5070 Mobile vs NVIDIA Switch 2 GPU Comparison

Head-to-Head Benchmarks

The recorded database does not contain a direct head-to-head benchmark comparison between the NVIDIA GeForce RTX 5070 Mobile and the NVIDIA Switch 2 GPU. The head-to-head benchmark array is empty, and neither product registers a win in the wins columns. This absence of comparative data is itself informative: the two GPUs were not measured under identical test conditions, so any direct score-to-score comparison would be speculative.

What the database does provide is a benchmark profile for the RTX 5070 Mobile and a set of nearest rival comparisons. The Switch 2 GPU has no benchmark entries, no average score, and no rival list, which places it outside the measurable performance hierarchy that the database maintains. Its percentile rank of 50 against all GPUs is a neutral midpoint, but without actual scores, that percentile cannot be tied to specific workload performance.

For the RTX 5070 Mobile, the data shows a Geekbench OpenCL score of 122,238 and a Geekbench Vulkan score of 116,960. The Passmark suite records a G3D score of 20,355, a GPU compute score of 8,279, a G2D score of 896, and legacy DirectX scores of 129 (DX10), 192 (DX11), 93 (DX12), and 214 (DX9). The average benchmark score across all recorded tests is 29,928, placing it at the 75th percentile of all GPUs in the database.

The nearest rivals for the RTX 5070 Mobile show a tight cluster. The NVIDIA GeForce RTX 3070 Ti averages 29,945, which is 0.1% higher than the RTX 5070 Mobile. The AMD Radeon RX 6800 sits 0.6% ahead at 30,095, while the AMD Radeon RX 6700 leads by 1.7% at 30,433. The NVIDIA GeForce RTX 2080 Ti trails by 0.5% at 29,783. These deltas are all within roughly two percentage points, indicating that the RTX 5070 Mobile performs essentially on par with this group, with the RX 6700 holding the largest measured advantage.

Architecture Differences

The two GPUs diverge sharply in their underlying designs. The RTX 5070 Mobile uses the GB206 chip built on the Blackwell 2.0 architecture, fabricated on a 5 nm process by TSMC. The Switch 2 GPU uses the GA10B chip on the Ampere architecture, fabricated on an 8 nm process by Samsung. The node difference is significant: 5 nm versus 8 nm directly affects transistor density and power efficiency, though the database does not quantify the efficiency delta.

The RTX 5070 Mobile packs 21,900 million transistors across a 181 mm² die, yielding a transistor density of 121.0 million per square millimeter. The Switch 2 GPU has an unknown transistor count, a 200 mm² die, and no recorded density figure. Despite the larger die, the Switch 2 GPU carries far fewer execution units: 1,536 shading units, 48 texture mapping units, and 16 render output units. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs, which is three times the shading units, three times the TMUs, and three times the ROPs.

Ray tracing and tensor hardware follow the same pattern. The RTX 5070 Mobile has 36 RT cores and 144 tensor cores. The Switch 2 GPU has 12 RT cores and 48 tensor cores, exactly one third of each. This proportionality suggests the Switch 2 GPU is a scaled-down implementation of a similar architectural family, but the generation gap (Blackwell 2.0 versus Ampere) means the feature sets are not directly comparable.

Memory configurations also differ in capacity and type. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s of bandwidth at a memory clock of 1500 MHz (24 Gbps effective). The Switch 2 GPU uses 12 GB of LPDDR5X on the same 128-bit bus, but bandwidth drops to 102.4 GB/s at 800 MHz (6.4 Gbps effective). The bandwidth ratio is 3.75:1 in favor of the RTX 5070 Mobile, which is larger than the raw memory size difference.

Clock behavior also differs. The RTX 5070 Mobile has a base clock of 907 MHz and a boost clock of 1425 MHz. The Switch 2 GPU has a base clock of 561 MHz and a boost clock of 1400 MHz. The boost clocks are close, but the RTX 5070 Mobile sustains a much higher base clock, which matters for steady-state workloads.

Power envelopes are relatively close: the RTX 5070 Mobile is rated at 50 W TDP, while the Switch 2 GPU is rated at 40 W TDP. The RTX 5070 Mobile is an integrated graphics processor (IGP) with no power connectors and no suggested PSU, while the Switch 2 GPU lists no slot width or power connector details. The Switch 2 GPU has physical dimensions recorded (272 mm length, 116 mm height, 14 mm width) and a launch MSRP of 449 USD, while the RTX 5070 Mobile has no dimensions and no launch MSRP.

Compute throughput reflects the execution unit imbalance. The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 and the same 13.13 TFLOPS of FP16 (1:1 ratio). The Switch 2 GPU delivers 4.301 TFLOPS of FP32 and 8.602 TFLOPS of FP16 (2:1 ratio). The FP32 gap is roughly 3.05:1. In pixel rate, the RTX 5070 Mobile produces 68.40 GPixel/s versus 22.40 GPixel/s for the Switch 2 GPU, a 3.05:1 ratio. Texture rate is 205.2 GTexel/s versus 67.20 GTexel/s, also a 3.05:1 ratio. These consistent ratios indicate that the architectural scaling is uniform across the pipeline.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 Mobile connects via PCIe 5.0 x16 and has display outputs described as portable device dependent, while the Switch 2 GPU has no bus interface recorded and no display outputs.

Where Each One Wins

The RTX 5070 Mobile wins on raw compute across every measured dimension. Its FP32 throughput of 13.13 TFLOPS is more than three times the Switch 2 GPU's 4.301 TFLOPS. Its memory bandwidth of 384.0 GB/s is nearly four times the Switch 2 GPU's 102.4 GB/s. Its pixel rate and texture rate are each roughly three times higher. The 50 W TDP is only 25% higher than the Switch 2 GPU's 40 W TDP, meaning the RTX 5070 Mobile delivers substantially more performance per watt in absolute throughput terms, though the database does not record efficiency ratios.

The RTX 5070 Mobile also wins on architectural generation. Blackwell 2.0 on 5 nm is a newer design than Ampere on 8 nm. The RTX 5070 Mobile has three times the RT cores and tensor cores, which positions it better for ray-traced workloads and AI-accelerated features, assuming software scales with core counts. Its GDDR7 memory is a newer memory type than LPDDR5X, though the Switch 2 GPU's larger 12 GB capacity could accommodate larger data sets in memory.

The Switch 2 GPU wins on memory capacity. At 12 GB versus 8 GB, it holds 50% more data. For workloads that are capacity-bound rather than bandwidth-bound, such as large texture sets or high-resolution assets that fit within 12 GB but spill beyond 8 GB, the Switch 2 GPU could avoid swapping. The database does not include benchmark data to confirm this, but the capacity difference is factual.

The Switch 2 GPU also wins on physical integration. It is a console GPU with a complete device form factor (272 mm by 116 mm by 14 mm) and a 40 W TDP, designed for a fixed, portable system. The RTX 5070 Mobile is an IGP with no dimensions, meaning its physical footprint is defined by the host laptop. The Switch 2 GPU's lower TDP and self-contained design make it suitable for battery-constrained environments, while the RTX 5070 Mobile's higher TDP requires a laptop cooling solution.

The FP16 ratio difference matters for specific workloads. The Switch 2 GPU runs FP16 at 2:1 (8.602 TFLOPS), effectively doubling its FP32 rate in half-precision. The RTX 5070 Mobile runs FP16 at 1:1 (13.13 TFLOPS), meaning it does not gain throughput in half-precision but starts from a higher FP32 baseline. For FP16-heavy workloads, the Switch 2 GPU's relative uplift is larger, but the RTX 5070 Mobile's absolute FP16 score is still 1.53 times higher.

The Verdict

The data supports a clear separation of roles. The RTX 5070 Mobile is a higher-performance mobile GPU that sits at the 75th percentile of all GPUs in the database, with an average benchmark score of 29,928. It matches or slightly trails the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700, all within a 1.7% band. This makes it a competitive option for laptop-class performance in the Blackwell generation.

The Switch 2 GPU has no benchmark scores, no average, and no rivals. Its 50th percentile rank is a default position, not a measured result. The only performance indicators are its architectural specs: 4.301 TFLOPS FP32, 102.4 GB/s bandwidth, and 40 W TDP. These figures place it well below the RTX 5070 Mobile in every compute metric. The Switch 2 GPU's advantages are capacity (12 GB) and integration (console form factor, 449 USD launch MSRP), not throughput.

From the recorded data, the RTX 5070 Mobile is the choice for applications that demand raw compute, high bandwidth, and modern architecture features. Its threefold advantage in shading units, TMUs, ROPs, RT cores, tensor cores, FP32, pixel rate, and texture rate is decisive for graphically intensive tasks. The Switch 2 GPU is the choice for a fixed console platform where power draw is capped at 40 W, physical size is predefined, and memory capacity beyond 8 GB is required. The database does not indicate that the Switch 2 GPU competes in the same performance class.
