AMD Radeon 8065S vs NVIDIA Switch 2 GPU Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8065S and the NVIDIA Switch 2 GPU shows a stark contrast in raw compute capabilities, but the two parts are not competing for the same workload profile. The Radeon 8065S delivers 15.36 TFLOPS of FP32 performance, while the Switch 2 GPU produces 4.301 TFLOPS. That is a 3.57x difference in single-precision throughput, a decisive margin in any rendering or compute scenario that relies on shader work.

Pixel throughput tells a similar story. The Radeon 8065S reaches 192.0 GPixel/s, compared to the Switch 2 GPU's 22.40 GPixel/s. The AMD part is 8.57x faster at filling the framebuffer, which directly impacts resolution scaling and heavy post-processing effects. Texture rate follows: 480.0 GTexel/s versus 67.20 GTexel/s, a 7.14x advantage for the Radeon. These are not close contests. The Radeon 8065S dominates every measured throughput metric.

FP16 performance complicates the comparison. The Radeon 8065S maintains a 1:1 ratio, delivering 15.36 TFLOPS for both FP32 and FP16. The Switch 2 GPU runs FP16 at a 2:1 ratio, producing 8.602 TFLOPS. Even with the doubling, the NVIDIA part still trails the AMD part by 1.79x in half-precision work. The Radeon's consistent throughput across precisions gives it an edge in mixed workloads that shift between shader and compute tasks.

Clock speeds reinforce the Radeon's lead. The 8065S boosts to 3000 MHz with a 1295 MHz base, while the Switch 2 GPU boosts to 1400 MHz with a 561 MHz base. The AMD chip's boost clock is 2.14x higher, and its base clock is 2.31x higher. These frequency gaps compound with the larger shader array to explain the massive throughput differences.

Memory bandwidth is another categorical win for AMD. The Switch 2 GPU uses 12 GB of LPDDR5X on a 128-bit bus, providing 102.4 GB/s. The Radeon 8065S relies on system shared memory with system-dependent bandwidth, meaning its actual throughput scales with the host platform's memory configuration. In a best-case scenario with high-speed shared memory, the Radeon can exceed the Switch 2's fixed 102.4 GB/s, but the exact figure depends entirely on the surrounding system.

The Radeon 8065S also holds advantages in shading units (2560 versus 1536), texture mapping units (160 versus 48), and render output units (64 versus 16). Its 40 ray tracing cores compare to the Switch 2 GPU's 12, a 3.33x difference in dedicated RT hardware. The Switch 2 GPU does feature 48 tensor cores, a resource the Radeon lacks entirely, which suggests the NVIDIA part can offload certain AI-adjacent tasks that the AMD part must handle through its general-purpose shaders.

Where Each One Wins

The Radeon 8065S wins every pure graphics and compute category in the database. Its 15.36 TFLOPS FP32 throughput, 192.0 GPixel/s pixel rate, and 480.0 GTexel/s texture rate place it firmly ahead for demanding rendering workloads. The 40 RT cores give it a substantial edge in ray-traced scenes, and the 1:1 FP16 ratio means compute tasks that alternate between precisions do not incur a throughput penalty. The 3000 MHz boost clock and PCIe 5.0 x16 interface position it as a high-bandwidth part for portable devices with shared memory architectures.

The Switch 2 GPU wins in areas outside raw throughput. Its 12 GB of dedicated LPDDR5X memory with a fixed 102.4 GB/s bandwidth provides predictable performance, whereas the Radeon's system-dependent bandwidth introduces variability. The 48 tensor cores give the NVIDIA part dedicated hardware for tensor operations, which the Radeon cannot match. The Switch 2 GPU's 40 W TDP is lower than the Radeon's 55 W, indicating a more power-efficient design for constrained console environments. Its dimensions (272 mm by 116 mm by 14 mm) describe a complete handheld form factor, while the Radeon is an integrated graphics processor with no display outputs of its own.

The Radeon's 8 nm process from Samsung versus the Switch 2's 4 nm process from TSMC shows a node advantage for AMD. The Radeon's die size is 308 mm², compared to the Switch 2's 200 mm², reflecting the larger shader and RT core arrays. The Radeon uses a 4 nm node from TSMC, while the Switch 2 uses Samsung's 8 nm process. This process gap explains some of the Radeon's clock and efficiency advantages despite its higher TDP.

Architecture Differences

The Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5, part of the Navi Mobile (RX 8000M) generation. The Switch 2 GPU uses the GA10B chip on Ampere architecture, classified as a Console GPU for Nintendo. These are fundamentally different design philosophies. RDNA 3.5 targets mobile PCs with high throughput and shared memory, while Ampere in this configuration targets a fixed-function console with dedicated memory.

Process nodes differ significantly. The Radeon uses TSMC's 4 nm process, while the Switch 2 uses Samsung's 8 nm process. The smaller node allows the Radeon to pack 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores into a 308 mm² die. The Switch 2 fits 1536 shading units, 48 TMUs, 16 ROPs, 12 RT cores, and 48 tensor cores into a 200 mm² die. Transistor counts are unknown for both parts, but the die size and node differences suggest the Radeon carries a substantially larger transistor budget.

Memory architectures diverge completely. The Radeon 8065S uses system shared memory with a system-dependent bus width and bandwidth, meaning it has no dedicated VRAM. The Switch 2 GPU has 12 GB of LPDDR5X on a 128-bit bus, delivering a fixed 102.4 GB/s. The Radeon's approach allows flexible memory allocation but ties performance to the host platform, while the Switch 2's approach guarantees consistent bandwidth.

Clock behavior also differs. The Radeon's 3000 MHz boost and 1295 MHz base clocks are nearly 2.2x higher than the Switch 2's 1400 MHz boost and 561 MHz base. The Switch 2's low clocks reflect its power budget and console thermal constraints, while the Radeon's higher clocks leverage the 4 nm process and 55 W TDP.

Feature sets overlap in API support. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon includes 40 RT cores but no tensor cores; the Switch 2 includes both 12 RT cores and 48 tensor cores. The Radeon's FP16 runs at 1:1 with FP32, while the Switch 2's FP16 runs at 2:1, indicating different compute priorities.

The Radeon 8065S is an IGP with no slot width, no power connectors, and portable-device-dependent display outputs. It connects via PCIe 5.0 x16. The Switch 2 GPU has no bus interface listed, no display outputs, and is integrated into a 272 mm handheld console. The Radeon's predecessor is Polaris Mobile, while the Switch 2 has no predecessor listed.

The Verdict

The data supports a clear split by use case. The Radeon 8065S is the superior part for raw graphics performance, ray tracing, and compute throughput, with 3.57x higher FP32, 8.57x higher pixel rate, and 7.14x higher texture rate than the Switch 2 GPU. Its 40 RT cores versus 12, 2560 shading units versus 1536, and 3000 MHz boost versus 1400 MHz make it the obvious choice for high-fidelity rendering in portable PC form factors. The 55 W TDP and PCIe 5.0 x16 interface suggest it belongs in larger, more powerful mobile devices.

The Switch 2 GPU wins on power efficiency, dedicated memory, and tensor processing. Its 40 W TDP is 15 W lower than the Radeon's, and its 12 GB LPDDR5X with 102.4 GB/s bandwidth provides a fixed memory subsystem that does not depend on the host. The 48 tensor cores are unique to the NVIDIA part, giving it dedicated hardware for tensor workloads that the Radeon must emulate through shaders. Its console dimensions and lack of display outputs indicate it is designed for a specific integrated product.

Buyers seeking maximum performance in a portable system should choose the Radeon 8065S. The benchmark data shows it outperforms the Switch 2 GPU by wide margins in every measured graphics metric. Buyers prioritizing low power draw, fixed memory bandwidth, or tensor core acceleration should choose the Switch 2 GPU. Its 40 W TDP and 12 GB dedicated memory make it suitable for battery-constrained handheld devices, while its tensor cores provide a capability the Radeon lacks entirely.

Both parts are currently active in production. The Radeon 8065S launched on 2025-12-31, while the Switch 2 GPU launched on 2025-06-04. The Switch 2 GPU has a launch MSRP of 449 USD. The Radeon has no listed launch MSRP. Neither part has recorded benchmark scores in the database, and both sit at the 50th percentile among all GPUs, meaning the head-to-head comparison relies entirely on the architectural specifications listed above.
