Neither GPU has any benchmark scores listed, and their average benchmark scores are both zero. The percentile versus all GPUs is identical at 50 for both parts, which places them at the median of the database distribution, though this is based on the absence of measured data rather than any direct comparison.

The AMD Radeon AI PRO 9600D shows a raw FP32 throughput of 24.82 TFLOPS, which is more than double the 12.01 TFLOPS of the NVIDIA N1 20SM. This 2.07x difference in raw compute is the largest numerical gap between the two products. The texture rate favors AMD as well, with 387.8 GTexel/s versus 375.4 GTexel/s, a modest 3.3% advantage. Pixel throughput tells a different story: the AMD card renders 193.9 GPixel/s, which is 3.44x the 56.30 GPixel/s of the NVIDIA part.

Memory bandwidth heavily favors the AMD card. The Radeon AI PRO 9600D delivers 576.0 GB/s over a 256-bit bus, while the N1 20SM provides 273.2 GB/s on the same 256-bit width. That is a 2.11x bandwidth advantage for AMD. However, the NVIDIA part has a massive capacity edge: 128 GB of LPDDR5X versus 32 GB of GDDR6. The AMD card uses faster memory at 18 Gbps effective, while the NVIDIA part runs at 8.5 Gbps effective.

Clock speeds show an interesting split. The AMD card has a higher base clock at 1080 MHz versus 741 MHz, but the NVIDIA part has a higher boost clock at 2346 MHz versus 2020 MHz. The AMD card also lists a game clock of 1080 MHz, which matches its base clock, while the NVIDIA part has no game clock specified.

Shader core counts differ by 512 units. The AMD Radeon AI PRO 9600D carries 3072 shading units, 192 texture mapping units, and 96 render output units. The NVIDIA N1 20SM has 2560 shading units, 160 TMUs, and only 24 ROPs. The ROP count difference is substantial and explains the large pixel rate gap. AMD also has 48 ray tracing cores, while NVIDIA has 20 RT cores but adds 80 tensor cores, a feature AMD does not list.

Where Each One Wins

Based on the specification data, the AMD Radeon AI PRO 9600D wins in raw compute throughput, memory bandwidth, pixel fill rate, and texture fill rate. Its 24.82 TFLOPS FP32 performance makes it the stronger choice for general compute workloads that use standard shader instructions. The 576.0 GB/s memory bandwidth supports data-heavy rendering tasks, and the 193.9 GPixel/s pixel rate gives it a clear edge in fill-limited scenarios such as high-resolution rasterization with heavy overdraw.

The NVIDIA N1 20SM wins on memory capacity, boosting clock speed, and tensor core availability. Its 128 GB of LPDDR5X memory is four times the capacity of the AMD card, which suits workloads that require very large datasets resident on the GPU, such as certain inference or simulation tasks. The higher boost clock of 2346 MHz indicates the NVIDIA part can reach higher instantaneous frequencies under load, even though its base clock is lower. The presence of 80 tensor cores gives the N1 20SM a dedicated path for tensor operations, while the AMD card lists no tensor core count at all.

The AMD card wins on power efficiency indicators. Its TDP is listed at 150 W, while the NVIDIA part has an unknown TDP, making direct comparison impossible. The AMD card also has a defined power connector requirement of one 16-pin and a suggested PSU of 450 W. The NVIDIA part uses no power connectors and is an IGP form factor, which suggests it is designed for integration rather than discrete installation.

The AMD part wins on API support. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1 20SM lists N/A for DirectX, OpenGL, and Vulkan. This means the AMD card is ready for current graphics APIs, while the NVIDIA part has no recorded API compatibility.

The AMD card also wins on display output flexibility with one DisplayPort 2.1a connector, while the NVIDIA part has one HDMI output. Both use PCIe 5.0 x16 for host connection.

Architecture Differences

The AMD Radeon AI PRO 9600D uses the RDNA 4.0 architecture on the Navi 48 chip, fabricated on TSMC's 4 nm process. The NVIDIA N1 20SM uses the Blackwell 2.0 architecture on the GB20B chip, fabricated on TSMC's 5 nm process. The node difference gives AMD a density advantage: 151.0M transistors per mm² versus no density data for NVIDIA.

AMD's architecture is built around a wide shader array with 3072 shading units and a high ROP count of 96. This configuration prioritizes pixel throughput and general compute. The 48 RT cores handle ray tracing workloads. NVIDIA's architecture uses 2560 shading units but only 24 ROPs, which limits pixel output. The 20 RT cores are fewer, but the 80 tensor cores add a dedicated matrix math engine that AMD does not list.

Memory architecture differs in fundamental ways. AMD pairs GDDR6 with a 256-bit interface and achieves 576.0 GB/s. NVIDIA pairs LPDDR5X with a 256-bit interface but achieves only 273.2 GB/s. The capacity difference is stark: 32 GB versus 128 GB. This suggests AMD optimizes for bandwidth per watt, while NVIDIA optimizes for capacity per package.

Clock strategy differs between the two architectures. AMD uses a conservative 1080 MHz base and game clock with a 2020 MHz boost. NVIDIA uses a low 741 MHz base but a high 2346 MHz boost, indicating a more aggressive dynamic clocking approach. The AMD card has a defined 150 W TDP, while NVIDIA does not disclose power consumption.

API support reflects architectural priorities. AMD lists full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. NVIDIA lists N/A for all APIs, which, combined with the IGP form factor and no power connectors, suggests the N1 20SM is designed for a different deployment context than a traditional discrete GPU.

The AMD card has a defined physical footprint: single-slot, 241 mm long, 111 mm tall, 19 mm wide, with one DisplayPort 2.1a output. The NVIDIA part is IGP with no dimensions and one HDMI output. The AMD card has a predecessor (Radeon Pro Vega), while NVIDIA has none listed.

The Verdict

The data shows two GPUs with different design philosophies. The AMD Radeon AI PRO 9600D is a discrete, single-slot card with a 150 W TDP, full API support, and high bandwidth. It delivers 24.82 TFLOPS FP32, 576.0 GB/s bandwidth, and 193.9 GPixel/s pixel rate. The NVIDIA N1 20SM is an IGP with 128 GB of memory, 80 tensor cores, and a high boost clock of 2346 MHz, but it has no API support listed and no power figures.

For users who need raw shader throughput, memory bandwidth, and pixel fill, the AMD card is the clear choice based on the recorded specifications. Its 24.82 TFLOPS is more than double the NVIDIA part, and its 576.0 GB/s bandwidth is more than double as well. The AMD card also supports current graphics APIs, making it suitable for standard rendering workloads.

For users who need maximum memory capacity for large datasets, the NVIDIA part is the only option. Its 128 GB of LPDDR5X is four times the AMD card's 32 GB. The tensor cores provide a dedicated path for tensor operations, which AMD does not offer. The NVIDIA part also has a higher boost clock, which may help in short bursts of compute activity.

The AMD card is built for traditional GPU workloads: rendering, rasterization, and compute with standard shaders. It has the ROP count, texture units, and bandwidth to sustain those tasks. The NVIDIA part is built for capacity and tensor acceleration, but its 24 ROPs and lower bandwidth limit its traditional rendering performance.

The production status is active for both, and both use PCIe 5.0 x16. The AMD card has a defined power requirement of 150 W with a 450 W suggested PSU, while the NVIDIA part has no power connectors, reflecting its IGP design.

The release dates differ by about six months, with AMD launching on 2025-12-10 and NVIDIA on 2026-05-31. The AMD card has a predecessor in the Radeon Pro Vega, while the NVIDIA part does not.

The database shows no benchmark results for either GPU, so real-world performance cannot be confirmed. The specification analysis indicates the AMD card wins on compute throughput, bandwidth, and pixel rate, while the NVIDIA card wins on memory capacity and tensor cores. The choice depends on whether the workload prioritizes bandwidth and shader throughput or capacity and tensor operations.
