Architecture Differences

The AMD Radeon PRO W7800 is built on the Navi 31 chip with the RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Radeon Pro Navi (Navi III Series) generation. It is fabricated at TSMC on a 5 nm process and contains 57,700 million transistors on a 529 mm² die, resulting in a transistor density of 109.1M per mm². The NVIDIA N1X 48SM uses the GB20B chip with the Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. It is also fabricated at TSMC on a 5 nm process, but its transistor count is listed as unknown and its die size is 382 mm² with no transistor density data.

The compute configurations differ significantly. The AMD Radeon PRO W7800 has 4,480 shading units, 280 texture mapping units, 128 ROPs, and 70 ray tracing cores, with no tensor cores listed. The NVIDIA N1X 48SM has 6,144 shading units, 384 texture mapping units, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The higher TMU count on the NVIDIA card supports its texture rate of 900.9 GTexel/s, while the AMD card reaches 707.0 GTexel/s.

Memory architecture diverges sharply. The AMD Radeon PRO W7800 uses 32 GB of GDDR6 with a 256-bit bus and 576.0 GB/s bandwidth, running at 2250 MHz (18 Gbps effective). The NVIDIA N1X 48SM uses 128 GB of LPDDR5X with a 256-bit bus and 273.2 GB/s bandwidth, running at 1067 MHz (8.5 Gbps effective). Although the NVIDIA card has quadruple the capacity, its bandwidth is less than half of the AMD card's.

API support also differs. The AMD Radeon PRO W7800 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan, which aligns with its IGP classification and lack of dedicated graphics API compatibility in the database. The AMD card is a dual-slot PCIe 4.0 x16 add-in board with 2x 8-pin power connectors and a suggested 600 W PSU, while the NVIDIA card is an IGP with PCIe 5.0 x16 interface, no power connectors, and no suggested PSU.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Radeon PRO W7800 and the NVIDIA N1X 48SM, and the NVIDIA card has no individual benchmark scores recorded. Therefore, comparison must rely on the AMD card's recorded results and architectural data.

The AMD Radeon PRO W7800 records a Geekbench OpenCL score of 154,366 and a Geekbench Vulkan score of 175,422. These scores place the card at the 97th percentile among all GPUs in the database. The NVIDIA N1X 48SM sits at the 50th percentile with no benchmark scores, meaning its position reflects only the default unmeasured baseline rather than tested performance.

The closest comparable data comes from the AMD card's nearest rivals. The Radeon PRO W7800's average score of 164,894 trails the NVIDIA RTX A5500 (165,217) by 0.2% and the NVIDIA RTX 4500 Ada Generation (166,094) by 0.7%. It leads the NVIDIA A100 PCIe 40 GB (162,504) by 1.5% and trails the AMD Radeon Pro W6900X (168,574) by 2.2%. These deltas show that the Radeon PRO W7800 is effectively performance-competitive with a cluster of high-end workstation GPUs, with all differences under 2.5%.

In raw throughput metrics, the AMD card leads in FP32 compute at 45.25 TFLOPS versus 28.83 TFLOPS for the NVIDIA card, and in FP16 at 90.50 TFLOPS (2:1) versus 28.83 TFLOPS (1:1). The AMD card also leads in pixel rate at 323.2 GPixel/s versus 112.6 GPixel/s. The NVIDIA card leads in texture rate at 900.9 GTexel/s versus 707.0 GTexel/s, and in shading unit count at 6,144 versus 4,480.

The Verdict

The recorded data indicates that the AMD Radeon PRO W7800 is the performance-validated product, with a 97th percentile standing and two Geekbench scores confirming its capability. The NVIDIA N1X 48SM has no benchmark results, placing it at the 50th percentile by default. Any selection between the two based on measured performance must favor the AMD card, as it is the only one with verified scores.

The AMD Radeon PRO W7800 also offers higher FP32 and FP16 compute throughput, higher pixel rate, significantly higher memory bandwidth, and full workstation API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. It uses GDDR6 memory and a conventional dual-slot form factor with 2x 8-pin power connectors, making it suitable for standard workstation installations.

The NVIDIA N1X 48SM distinguishes itself with 128 GB of LPDDR5X memory, 6,144 shading units, 384 texture mapping units, and 192 tensor cores. Its IGP form factor with a single HDMI output and PCIe 5.0 x16 interface suggests a different deployment context, but the absence of benchmark data and unsupported graphics APIs in the database limits its measurable appeal. Users requiring verified compute performance and broad graphics API compatibility would select the AMD Radeon PRO W7800 based on the evidence available.
