Intel Arc B770 vs NVIDIA Switch 2 GPU Comparison

The Verdict

The Intel Arc B770 and NVIDIA Switch 2 GPU occupy entirely different segments of the graphics hardware spectrum. The Arc B770 is a desktop add-in board built for high-throughput rendering workloads, while the Switch 2 GPU is a low-power console component integrated into a handheld system. The recorded data shows both share a 50th percentile ranking among all GPUs in the database, yet their measured specifications diverge sharply.

The Arc B770 suits workloads demanding raw throughput, large frame buffers, and sustained compute. Its 19.66 TFLOPS FP32 throughput, 512.0 GB/s memory bandwidth, and 16 GB GDDR6 frame buffer position it for 1440p and 4K-class rendering tasks. The Switch 2 GPU, with 4.301 TFLOPS FP32, 102.4 GB/s bandwidth, and 12 GB LPDDR5X, targets constrained power envelopes and portable operation. Its 40 W TDP versus the Arc B770's 225 W TDP defines the fundamental trade-off.

The data indicates no direct benchmark comparisons exist between these two parts. The verdict rests on architectural specifications and intended deployment. For desktop rendering, content creation, or high-refresh gaming, the Arc B770 delivers roughly 4.6 times the FP32 throughput of the Switch 2 GPU. For embedded, fanless, or battery-powered systems, the Switch 2 GPU provides functional graphics at a fraction of the power draw.

Each GPU wins in its own domain. Neither part serves as a substitute for the other.

Architecture Differences

The Arc B770 uses the BMG-G31 chip built on TSMC's 5 nm process, with a die size of 368 mm². The Switch 2 GPU uses the GA10B chip on Samsung's 8 nm process, with a die size of 200 mm². The Arc B770 belongs to Intel's Battlemage generation under the Xe2-HPG architecture, while the Switch 2 GPU is an Ampere-architecture part in NVIDIA's console GPU line for Nintendo.

The compute resources differ by an order of magnitude. The Arc B770 contains 4096 shading units, 256 texture mapping units, 128 raster output units, and 32 ray tracing cores. The Switch 2 GPU contains 1536 shading units, 48 TMUs, 16 ROPs, 12 RT cores, and 48 tensor cores. The Arc B770 lists no tensor core count in the database, while the Switch 2 GPU carries dedicated tensor hardware.

Memory subsystems diverge substantially. The Arc B770 uses 16 GB of GDDR6 across a 256-bit bus, achieving 512.0 GB/s bandwidth. Memory clocks run at 2000 MHz with 16 Gbps effective data rate. The Switch 2 GPU uses 12 GB of LPDDR5X across a 128-bit bus, achieving 102.4 GB/s. Its memory clocks run at 800 MHz with 6.4 Gbps effective. The Arc B770 delivers exactly 5 times the memory bandwidth.

Clock behavior reflects the power envelope. The Arc B770 runs at a 2100 MHz base and 2400 MHz boost. The Switch 2 GPU runs at a 561 MHz base and 1400 MHz boost. The Arc B770's boost clock is 1000 MHz higher than the Switch 2 GPU's boost clock.

Rasterization and texture throughput follow the same pattern. The Arc B770 outputs 307.2 GPixel/s pixel fill rate and 614.4 GTexel/s texture fill rate. The Switch 2 GPU outputs 22.40 GPixel/s and 67.20 GTexel/s. The Arc B770's pixel rate is roughly 13.7 times higher and its texture rate roughly 9.1 times higher.

The Arc B770 draws 225 W and requires a 550 W suggested power supply, using one 6-pin and one 8-pin power connector. It occupies a dual-slot form factor and connects via PCIe 4.0 x16. Display outputs include one HDMI 2.1a and three DisplayPort 2.1 connectors. The Switch 2 GPU draws 40 W, lists no power connectors, no slot width, no bus interface, and no display outputs in the database. Its physical dimensions measure 272 mm long, 116 mm high, and 14 mm wide.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc B770 launched after the Switch 2 GPU in the database records, with the Switch 2 GPU release date in early June 2025 and the Arc B770 at the end of December 2025. The Switch 2 GPU carries a launch MSRP of 449 USD, while the Arc B770 lists no launch MSRP.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark records for these two GPUs. The wins comparison shows zero wins for each part. The comparison therefore relies on the recorded specification data.

The largest computational gap appears in FP32 throughput. The Arc B770 delivers 19.66 TFLOPS against the Switch 2 GPU's 4.301 TFLOPS, a difference of 15.359 TFLOPS. This translates to roughly 4.57 times the single-precision compute performance. FP16 performance follows the same ratio: 39.32 TFLOPS versus 8.602 TFLOPS.

Memory bandwidth shows the next major separation. At 512.0 GB/s, the Arc B770 provides 409.6 GB/s more bandwidth than the Switch 2 GPU's 102.4 GB/s. This 5-fold advantage matters for texture streaming, large framebuffer workloads, and compute kernels that saturate memory.

Pixel throughput favors the Arc B770 by a wider margin. The 307.2 GPixel/s rate against 22.40 GPixel/s represents roughly 13.7 times the fill rate. Texture rate shows 614.4 GTexel/s versus 67.20 GTexel/s, roughly 9.1 times higher.

The Switch 2 GPU counters with power efficiency. At 40 W TDP, it delivers 4.301 TFLOPS, which calculates to approximately 107.5 GFLOPS per watt. The Arc B770 at 225 W delivers 19.66 TFLOPS, approximately 87.4 GFLOPS per watt. The Switch 2 GPU produces roughly 23 percent more FP32 throughput per watt.

The Switch 2 GPU also holds advantages in physical integration. It measures 272 mm by 116 mm by 14 mm and carries no external power requirement beyond its 40 W envelope. The Arc B770 requires a dual-slot cooler, two power connectors, and a 550 W power supply. These factors define deployment scenarios rather than raw performance.

Ray tracing hardware differs in count but not in architecture-specific behavior. The Arc B770 has 32 RT cores against the Switch 2 GPU's 12 RT cores. The tensor core count of 48 on the Switch 2 GPU has no recorded counterpart on the Arc B770, preventing a direct comparison of AI acceleration throughput.

High-refresh gaming favors the Arc B770. The 2400 MHz boost clock, 4096 shading units, and 128 ROPs provide the geometry and fill throughput needed for demanding scenes. The 32 RT cores add hardware ray tracing capacity beyond the Switch 2 GPU's 12 RT cores.

Multi-display setups favor the Arc B770. It records one HDMI 2.1a and three DisplayPort 2.1 outputs. The Switch 2 GPU records no display outputs, indicating integration into a device with its own display path.

Power-constrained systems favor the Switch 2 GPU. Its 40 W TDP enables operation in handheld or fanless configurations where a 225 W part cannot function. The FP32-per-watt calculation shows the Switch 2 GPU at roughly 107.5 GFLOPS per watt versus the Arc B770's 87.4 GFLOPS per watt.

Portable gaming favors the Switch 2 GPU. Its 272 mm by 116 mm by 14 mm dimensions and absence of external power connectors allow integration into a compact device. The 12 GB LPDDR5X memory balances capacity against the 102.4 GB/s bandwidth for the target resolution class.

Embedded deployment favors the Switch 2 GPU. The Active production status, lower TDP, and 8 nm Samsung process indicate a part designed for volume manufacturing in a fixed hardware platform. The Arc B770's 5 nm TSMC process and 368 mm² die target desktop expansion cards.

AI-adjacent workloads where tensor cores matter favor the Switch 2 GPU by specification. It lists 48 tensor cores, while the Arc B770 records no tensor core count. The database does not provide comparative tensor performance metrics.

The raw performance divide remains decisive for any workload that scales with shading units, memory bandwidth, or fill rate. The Arc B770 leads in every recorded throughput metric. The Switch 2 GPU leads in power efficiency and physical integration. The recorded data supports no crossover scenario where the Switch 2 GPU outperforms the Arc B770 in absolute rendering speed, nor any scenario where the Arc B770 matches the Switch 2 GPU's power draw.
