AMD Radeon PRO W7800 vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison scenario. The AMD Radeon PRO W7800 has two benchmark entries in the database, while the NVIDIA N1 16SM has no recorded benchmarks. The database shows the W7800 scoring 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan, resulting in an average benchmark score of 164,894. The N1 16SM holds an average benchmark score of 0, with an empty benchmark array. This absence of measured performance data for the N1 16SM means the head-to-head comparison relies on the W7800's positioning against its nearest rivals rather than direct N1 16SM comparisons.

The W7800 sits at the 97th percentile among all GPUs in the database. Its nearest rival, the NVIDIA RTX A5500, posts an average score of 165,217, which places it 0.2% ahead of the W7800. The NVIDIA RTX 4500 Ada Generation averages 166,094, a 0.7% advantage over the W7800. The AMD Radeon Pro W6900X reaches 168,574, putting it 2.2% ahead. The NVIDIA A100 PCIe 40 GB trails the W7800 by 1.5%, with an average score of 162,504. These deltas are all within a narrow band, suggesting the W7800 competes closely with professional workstation GPUs from the previous generation.

The N1 16SM's 50th percentile ranking reflects its lack of benchmark data. Without scores, the database cannot compute deltas or establish a performance relationship between the two cards. The W7800's 97th percentile places it firmly in the upper tier of all recorded GPUs, while the N1 16SM's position is a placeholder pending measurement results.

The Verdict

The data points to a clear distinction in roles. The AMD Radeon PRO W7800 delivers measurable compute performance, with its 45.25 TFLOPS FP32 throughput and 90.50 TFLOPS FP16 throughput (2:1 ratio) placing it among high-end workstation accelerators. Its nearest rivals all fall within a 2.2% window of its average benchmark score, indicating a competitive field. The W7800's 97th percentile ranking confirms strong standing in the database.

The NVIDIA N1 16SM presents a different profile. Its FP32 throughput of 9.609 TFLOPS matches its FP16 throughput at a 1:1 ratio, a configuration that suggests different design priorities. With no benchmark scores recorded, the database cannot validate its real-world performance. The N1 16SM's 50th percentile is an artifact of missing data, not a measured result.

Workstation buyers with compute workloads would find the W7800's benchmark records useful for comparison against RTX A5500 and RTX 4500 Ada Generation cards. The N1 16SM, as an IGP with a PCIe 5.0 x16 interface and no power connectors, targets a different integration model. Its 128 GB of LPDDR5X memory with 273.2 GB/s bandwidth suggests a memory-capacity-oriented design, but the absence of measured scores leaves its compute position unresolved.

Architecture Differences

The two chips come from different architectural lineages. The AMD Radeon PRO W7800 uses the Navi 31 chip built on RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA N1 16SM uses the GB20B chip built on Blackwell 2.0 architecture and belongs to the Blackwell IGP (N1x) generation. Both are fabricated by TSMC on a 5 nm process.

Transistor counts differ sharply. The W7800 packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The N1 16SM's transistor count is listed as unknown, though its die size measures 382 mm². The W7800 is a large discrete GPU, while the N1 16SM's IGP form factor points to an integrated solution.

Compute resources diverge significantly. The W7800 features 4,480 shading units, 280 texture mapping units, 128 ROPs, and 70 ray tracing cores. The N1 16SM has 2,048 shading units, 128 TMUs, 24 ROPs, and 16 ray tracing cores. The N1 16SM includes 64 tensor cores, while the W7800 lists no tensor core count. Clock behavior also differs: the W7800 runs at a base of 1895 MHz with a 2525 MHz boost, while the N1 16SM operates at a 741 MHz base and 2346 MHz boost.

Memory architectures show different priorities. The W7800 uses 32 GB of GDDR6 on a 256-bit bus, achieving 576.0 GB/s bandwidth with 18 Gbps effective memory speed. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus, reaching 273.2 GB/s bandwidth with 8.5 Gbps effective speed. The N1 16SM trades bandwidth for capacity, offering four times the memory at less than half the bandwidth.

API support separates them completely. The W7800 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A. Display outputs also differ: the W7800 provides three DisplayPort 2.1 and one mini-DisplayPort 2.1, while the N1 16SM offers a single HDMI output.

Power delivery reflects their form factors. The W7800 carries a 260 W TDP, uses two 8-pin power connectors, and requires a 600 W suggested PSU. It occupies a dual-slot design at 280 mm length, 110 mm height, and 40 mm width. The N1 16SM has an unknown TDP, no power connectors, and an IGP slot width with no listed dimensions.

Where Each One Wins

The AMD Radeon PRO W7800 wins on raw compute metrics. Its 45.25 TFLOPS FP32 and 90.50 TFLOPS FP16 throughput dwarf the N1 16SM's 9.609 TFLOPS in both precisions. The W7800 also leads in texture rate at 707.0 GTexel/s versus 300.3 GTexel/s, and pixel rate at 323.2 GPixel/s versus 56.30 GPixel/s. The W7800's 576.0 GB/s memory bandwidth supports bandwidth-hungry workloads, and its 70 ray tracing cores enable hardware-accelerated ray tracing. Its benchmark scores place it at the 97th percentile, with nearest rivals within a 2.2% margin.

The NVIDIA N1 16SM wins on memory capacity. Its 128 GB of LPDDR5X exceeds the W7800's 32 GB by a factor of four, which suits workloads that require large datasets resident in memory. The N1 16SM also includes 64 tensor cores, a feature the W7800 does not list. Its IGP form factor with no power connectors and unknown TDP suggests low integration overhead. The PCIe 5.0 x16 interface provides a newer bus generation than the W7800's PCIe 4.0 x16. The N1 16SM's 1:1 FP16 to FP32 ratio indicates consistent throughput across both precisions, contrasting with the W7800's 2:1 ratio.
