AMD Radeon PRO W7700 vs NVIDIA N1 16SM Comparison

Where Each One Wins

The recorded data splits these two parts cleanly by workload category. The AMD Radeon PRO W7700 has two benchmark entries in the database: Geekbench OpenCL at 108,245 and Geekbench Vulkan at 129,706. Its average benchmark score across recorded tests is 118,976, which places it in the 95th percentile of all GPUs tracked. The NVIDIA N1 16SM, by contrast, has no recorded benchmark scores in the database, an average benchmark score of zero, and sits at the 50th percentile. On raw compute performance, the AMD part wins every measured comparison.

The AMD Radeon PRO W7700 delivers 31.95 TFLOPS of FP32 compute and 63.90 TFLOPS of FP16 compute at a 2:1 ratio. The NVIDIA N1 16SM delivers 9.609 TFLOPS of FP32 and 9.609 TFLOPS of FP16 at a 1:1 ratio. That means the AMD part provides roughly 3.3 times the FP32 throughput and roughly 6.6 times the FP16 throughput when the AMD part uses its accelerated path. For any task that relies on raw shader throughput, the W7700 is the clear winner.

However, the N1 16SM has one decisive advantage: memory capacity. The NVIDIA part carries 128 GB of LPDDR5X memory on a 256-bit bus, versus 16 GB of GDDR6 on a 256-bit bus for the AMD part. The AMD part has higher memory bandwidth at 576.0 GB/s versus 273.2 GB/s, but the N1 16SM has eight times the capacity. For workloads that need to hold very large datasets in local memory without spilling to system RAM, the N1 16SM wins on capacity alone.

The AMD part also wins on display output flexibility. It offers four DisplayPort 2.1 connections, while the N1 16SM offers a single HDMI output. The AMD card is a dual-slot PCIe 4.0 x16 add-in board with a single 8-pin power connector and a suggested 450 W power supply. The N1 16SM is an integrated graphics processor with no power connectors and a PCIe 5.0 x16 interface. The W7700 is a discrete workstation card; the N1 16SM is an IGP.

Architecture Differences

The two parts come from different architectural families. The AMD Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas. It is part of the Radeon Pro Navi generation (Navi III Series). The NVIDIA N1 16SM uses the GB20B chip built on Blackwell 2.0 architecture, listed as part of the Blackwell IGP generation (N1x). Both are manufactured on a 5 nm process at TSMC, but the similarity ends there.

The AMD chip contains 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2M per mm². The NVIDIA die is slightly larger at 382 mm², but its transistor count is listed as unknown, so no density figure can be computed. The AMD part has 3,072 shading units, 192 texture mapping units, and 96 render output units. The NVIDIA part has 2,048 shading units, 128 TMUs, and only 24 ROPs. The AMD part has 48 ray tracing cores; the NVIDIA part has 16 ray tracing cores. The NVIDIA part includes 64 tensor cores, while the AMD part does not list tensor cores at all.

Clock behavior differs substantially. The AMD part runs at a 1900 MHz base clock and a 2600 MHz boost clock. The NVIDIA part runs at a 741 MHz base clock and a 2346 MHz boost clock. The NVIDIA part has a much lower base clock but a boost clock that approaches the AMD part. Memory clocks also differ: the AMD memory runs at 2250 MHz with 18 Gbps effective, while the NVIDIA memory runs at 1067 MHz with 8.5 Gbps effective.

The memory subsystems are different in type and capacity. The AMD part uses 16 GB of GDDR6 with a 256-bit bus and 576.0 GB/s of bandwidth. The NVIDIA part uses 128 GB of LPDDR5X with a 256-bit bus and 273.2 GB/s of bandwidth. The pixel and texture rates reflect the ROP and TMU counts: the AMD part achieves 249.6 GPixel/s and 499.2 GTexel/s, while the NVIDIA part achieves 56.30 GPixel/s and 300.3 GTexel/s.

API support also separates the two. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists DirectX, OpenGL, and Vulkan as N/A. The AMD part is a PCIe 4.0 x16 card; the NVIDIA part uses PCIe 5.0 x16. The AMD part has a 190 W TDP and a dual-slot cooler; the NVIDIA part has an unknown TDP and is an IGP form factor. The AMD part measures 241 mm in length and 111 mm in height; the NVIDIA part has no recorded dimensions.

The release dates also differ. The AMD Radeon PRO W7700 was released on November 12, 2023, with a launch MSRP of 999 USD. The NVIDIA N1 16SM has a release date of May 31, 2026, and its production status is listed as Active. The AMD part's predecessor is the Radeon Pro Vega; the NVIDIA part has no listed predecessor or successor.

The Verdict

The data supports a clear split by use case. For compute performance, the AMD Radeon PRO W7700 is the only part with recorded benchmark scores, and those scores are strong. Its average benchmark score of 118,976 places it in the 95th percentile, and its nearest rivals in the database include the NVIDIA GB10 at 117,393 (1.3% behind), the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (1.6% behind), the NVIDIA Tesla V100 SXM2 16 GB at 114,395 (4% behind), and the NVIDIA RTX A5500 Mobile at 113,944 (4.4% behind). The W7700 leads all of them in the database's average score.

For memory capacity, the NVIDIA N1 16SM is the only option. Its 128 GB of LPDDR5X is eight times the capacity of the AMD part's 16 GB. That is a decisive advantage for workloads that need to keep large models or datasets resident in GPU memory. The N1 16SM also has tensor cores (64 of them), which the AMD part does not list, and it consumes no dedicated power connectors as an IGP.

The AMD part wins on bandwidth, pixel rate, texture rate, FP32 throughput, FP16 throughput, display outputs, and API support. The NVIDIA part wins on memory capacity, tensor core availability, PCIe 5.0 interface, and a smaller physical footprint (IGP versus dual-slot card). The database contains no head-to-head benchmark results between these two parts, so all comparisons rely on the separately recorded specs and the W7700's benchmark entries.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark comparisons between the AMD Radeon PRO W7700 and the NVIDIA N1 16SM. However, the W7700's recorded benchmark scores and the N1 16SM's absence of recorded scores create a clear performance gap. The W7700's Geekbench Vulkan score of 129,706 is its higher result, while its Geekbench OpenCL score of 108,245 is lower. The average of 118,976 puts it ahead of its nearest recorded rivals: the NVIDIA GB10 scores 117,393 (1.3% lower), the NVIDIA RTX 4000 SFF Ada Generation scores 117,088 (1.6% lower), the NVIDIA Tesla V100 SXM2 16 GB scores 114,395 (4% lower), and the NVIDIA RTX A5500 Mobile scores 113,944 (4.4% lower).

The largest single-spec win for the AMD part is in FP16 compute. The W7700 delivers 63.90 TFLOPS at a 2:1 ratio, versus 9.609 TFLOPS at a 1:1 ratio for the N1 16SM. That is more than a sixfold advantage. The FP32 advantage is smaller but still substantial: 31.95 TFLOPS versus 9.609 TFLOPS, or roughly 3.3 times.

The largest single-spec win for the NVIDIA part is memory capacity. The N1 16SM has 128 GB versus 16 GB for the W7700, an eightfold difference. The N1 16SM also has a larger die at 382 mm² versus 346 mm², though its transistor count is unknown, so density cannot be compared. The N1 16SM lists 64 tensor cores; the W7700 has none listed. The N1 16SM uses a PCIe 5.0 x16 interface versus PCIe 4.0 x16 for the W7700.

The AMD part wins on bandwidth by a factor of roughly 2.1 (576.0 GB/s versus 273.2 GB/s). It wins on pixel rate by a factor of roughly 4.4 (249.6 GPixel/s versus 56.30 GPixel/s). It wins on texture rate by a factor of roughly 1.7 (499.2 GTexel/s versus 300.3 GTexel/s). It has more shading units (3,072 versus 2,048), more TMUs (192 versus 128), more ROPs (96 versus 24), and more RT cores (48 versus 16). The AMD part supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4; the NVIDIA part lists all three as N/A.

The AMD part has a boost clock of 2600 MHz versus 2346 MHz for the NVIDIA part, and a base clock of 1900 MHz versus 741 MHz. The AMD memory runs at 18 Gbps effective versus 8.5 Gbps effective for the NVIDIA part. The W7700 uses a single 8-pin power connector with a 190 W TDP and a suggested 450 W power supply; the N1 16SM uses no power connectors and has an unknown TDP. The W7700 is a dual-slot card measuring 241 mm by 111 mm; the N1 16SM is an IGP with no recorded dimensions.

The benchmark data confirms that the AMD Radeon PRO W7700 is the compute-oriented part, while the NVIDIA N1 16SM is the capacity-oriented part. The W7700's 95th percentile ranking and its leading average score among its nearest rivals indicate strong general compute performance. The N1 16SM's 50th percentile ranking with no recorded scores leaves its actual performance unmeasured in the database, but its 128 GB memory pool and tensor cores define its role differently.
