Intel Arc G3 vs NVIDIA Switch 2 GPU Comparison

Head-to-Head Benchmarks

The database currently contains no recorded benchmark scores for either the Intel Arc G3 or the NVIDIA Switch 2 GPU. Both entries have an average benchmark score of zero, and the head-to-head benchmark array is empty. This absence of measured data means direct performance comparisons cannot be drawn from numeric results. What can be analyzed, however, is the theoretical throughput derived from each chip's specification sheet, which offers a baseline for understanding their respective computational ceilings.

The Intel Arc G3 delivers a peak FP32 rate of 6.144 TFLOPS, while the NVIDIA Switch 2 GPU reaches 4.301 TFLOPS. This places the Arc G3 roughly 43% ahead of the Switch 2 GPU in raw single-precision compute. In FP16 throughput, the Arc G3 achieves 12.29 TFLOPS (2:1), compared to 8.602 TFLOPS (2:1) for the Switch 2 GPU, a lead of approximately 43% again. These numbers suggest that for workloads relying heavily on shader arithmetic, the Arc G3 holds a clear theoretical advantage.

Pixel throughput tells a different story. The Arc G3 is rated at 48.00 GPixel/s, while the Switch 2 GPU delivers 22.40 GPixel/s. That is a 114% difference in favor of the Arc G3, indicating a substantially higher fill-rate capacity. Texture rate follows a similar pattern: 96.00 GTexel/s for the Arc G3 versus 67.20 GTexel/s for the Switch 2 GPU, a 43% gap. These figures imply that the Arc G3 can drive higher resolution rendering and more complex texture filtering in theory.

The Switch 2 GPU does not come out entirely empty-handed. Its memory configuration is fixed and dedicated: 12 GB of LPDDR5X on a 128-bit bus, yielding 102.4 GB/s of bandwidth. The Arc G3 uses system-shared memory with bandwidth described as system dependent. In a scenario where the host system provides ample memory bandwidth, the Arc G3 could match or exceed the Switch 2 GPU, but the Switch 2 GPU has a guaranteed, consistent bandwidth figure that does not depend on external factors.

Clock speeds also differ notably. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The Switch 2 GPU operates at a base of 561 MHz and boosts to 1400 MHz. The Arc G3's boost clock is 71% higher, which contributes to its higher peak throughput despite having fewer shading units. The Switch 2 GPU compensates with a higher base clock, 87% above the Arc G3's base, which could indicate better sustained performance at lower power states.

Architecture Differences

The Intel Arc G3 is built on the Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation. It uses a 3 nm process node fabricated by Intel. The NVIDIA Switch 2 GPU is based on the Ampere architecture, uses an 8 nm process node from Samsung, and belongs to the Console GPU (Nintendo) generation. The process node difference is substantial: 3 nm versus 8 nm, which typically correlates with significant differences in transistor density and power efficiency, though the exact transistor counts for both chips are listed as unknown.

The Arc G3's die size is unknown, while the Switch 2 GPU has a die size of 200 mm². Without the Arc G3's die dimensions, a direct density comparison is impossible. The Switch 2 GPU's larger process node combined with a known die size suggests it likely uses fewer transistors per square millimeter than the Arc G3, but the database does not provide transistor density figures for either chip.

Core counts differ in several respects. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The Switch 2 GPU has 1536 shading units, 48 texture mapping units, 16 raster output units, and 12 ray tracing cores. The Switch 2 GPU thus has 20% more shading units, 20% more TMUs, and 20% more ray tracing cores than the Arc G3, but 20% fewer ROPs. This is an unusual distribution: more shaders and TMUs with fewer ROPs suggests the Switch 2 GPU is designed for geometry and shading throughput, while the Arc G3's higher ROP count supports faster pixel output.

Tensor cores are present only on the Switch 2 GPU, which has 48 of them. The Arc G3 lists tensor cores as null. This is a key architectural difference, as tensor cores enable accelerated AI and machine learning workloads. The Arc G3's Xe3-LPG architecture does not appear to include a dedicated tensor core array in the recorded data.

Memory architecture diverges sharply. The Arc G3 uses system-shared memory for both size and type, with a system-shared bus width and system-dependent bandwidth. The Switch 2 GPU uses 12 GB of dedicated LPDDR5X memory on a 128-bit bus with a fixed 102.4 GB/s bandwidth. The memory clock for the Switch 2 GPU is listed as 800 MHz, 6.4 Gbps effective. The Arc G3's memory clock is simply described as system shared.

Power consumption figures are recorded. The Arc G3 has a TDP of 25 W, while the Switch 2 GPU has a TDP of 40 W. The Switch 2 GPU consumes 60% more power, which is notable given its lower peak FP32 throughput. This suggests the Arc G3 achieves higher compute per watt in theory, though the system-dependent nature of its memory subsystem could alter real-world efficiency.

The Verdict

The data indicates a clear theoretical performance advantage for the Intel Arc G3 in raw compute and fill-rate metrics. Its FP32 throughput is 43% higher than the Switch 2 GPU, its pixel rate is 114% higher, and its texture rate is 43% higher. These are substantial margins that would likely translate into better performance in shader-bound and fill-rate-bound scenarios, assuming the system-shared memory bandwidth is sufficient.

The NVIDIA Switch 2 GPU counters with a dedicated memory subsystem. Its 12 GB of LPDDR5X on a 128-bit bus delivers a fixed 102.4 GB/s, whereas the Arc G3's bandwidth is entirely dependent on the host system's memory configuration. In a constrained system, the Switch 2 GPU's consistent bandwidth could make it more reliable for memory-intensive workloads, even with lower peak compute.

The Switch 2 GPU also brings tensor cores to the table, which the Arc G3 lacks entirely. For AI inference or machine learning tasks, the 48 tensor cores on the Switch 2 GPU provide a capability that the Arc G3 cannot match. The Arc G3's 10 ray tracing cores versus the Switch 2 GPU's 12 ray tracing cores gives the latter a 20% advantage in that specific area, though the Arc G3's higher overall compute could still produce competitive ray tracing results.

The production status for both is listed as active. The release dates differ: the Switch 2 GPU was released in June 2025, while the Arc G3 has a release date in May 2026. The database includes a launch MSRP of 449 USD for the Switch 2 GPU, while the Arc G3 has no recorded launch MSRP.

Where Each One Wins

The Intel Arc G3 wins in raw compute throughput. Its 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 figures exceed the Switch 2 GPU's 4.301 TFLOPS and 8.602 TFLOPS by 43%. This makes the Arc G3 the stronger choice for shader-heavy workloads, general compute tasks, and any application that scales with FLOPs.

The Arc G3 also wins decisively in fill-rate metrics. Its pixel rate of 48.00 GPixel/s is more than double the Switch 2 GPU's 22.40 GPixel/s. Its texture rate of 96.00 GTexel/s exceeds the Switch 2 GPU's 67.20 GTexel/s by 43%. For high-resolution rendering, heavy texture filtering, or multi-sample anti-aliasing scenarios, the Arc G3 has a theoretical edge.

The Arc G3 wins on power efficiency in terms of compute per watt. It produces 6.144 TFLOPS at 25 W, while the Switch 2 GPU produces 4.301 TFLOPS at 40 W. The Arc G3's power-adjusted throughput is substantially higher, making it the preferable option for thermally constrained environments.

The NVIDIA Switch 2 GPU wins on memory consistency. Its 102.4 GB/s bandwidth is fixed and dedicated, while the Arc G3's bandwidth is system dependent. Applications that require predictable memory performance without reliance on host system configuration would favor the Switch 2 GPU.

The Switch 2 GPU wins on memory capacity. Its 12 GB of dedicated LPDDR5X is a concrete figure, whereas the Arc G3's system-shared memory size is unspecified. For workloads that demand a known minimum memory allocation, the Switch 2 GPU provides certainty.
