AMD Radeon RX 7700S vs NVIDIA N1 16SM Comparison

The Verdict

The database shows two fundamentally different mobile graphics solutions. The AMD Radeon RX 7700S is an active, shipping discrete GPU with recorded benchmark scores and a strong 78th percentile ranking among all GPUs. The NVIDIA N1 16SM is a Blackwell IGP with no recorded benchmarks, an average score of zero, and a 50th percentile placeholder. For any workload represented by the available measurements, the RX 7700S is the only option with demonstrated performance data. The N1 16SM cannot be evaluated on raw speed because the database contains no test results for it. Its 128 GB memory capacity and PCIe 5.0 interface are notable specifications, but without benchmark scores, those features do not translate into measurable performance. The RX 7700S is the choice for any user requiring validated graphics performance today. The N1 16SM is a future product, dated later in the database, with architectural advantages on paper but zero verified results.

Architecture Differences

The AMD Radeon RX 7700S uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi Mobile generation within the RX 7000M family. It is fabricated on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die. The NVIDIA N1 16SM uses the GB20B chip on Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation, also fabricated at TSMC but on a 5 nm process. Its die size is 382 mm², notably larger, while its transistor count is listed as unknown.

The RX 7700S implements DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan support as N/A. The RX 7700S has 32 ray tracing cores and no tensor cores. The N1 16SM has 16 ray tracing cores and 64 tensor cores, indicating a different compute focus. The RX 7700S delivers 20.48 TFLOPS FP32 and 40.96 TFLOPS FP16 at a 2:1 ratio. The N1 16SM delivers 9.609 TFLOPS FP32 and the same 9.609 TFLOPS FP16 at a 1:1 ratio. The RX 7700S uses a 128-bit GDDR6 memory interface with 8 GB capacity, while the N1 16SM uses a 256-bit LPDDR5X interface with 128 GB capacity. Both are integrated or portable-device solutions: the RX 7700S is listed with slot width IGP and power connectors None, as is the N1 16SM, though the N1 16SM has one HDMI display output while the RX 7700S has portable device dependent outputs.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Radeon RX 7700S and the NVIDIA N1 16SM. The RX 7700S has its own benchmark suite, however, and those results place it in a specific performance tier. In 3DMark Steel Nomad DX12, the RX 7700S scores 2185. In Geekbench OpenCL, it scores 62983. In Geekbench Vulkan, it scores 36380. Its average benchmark score across all tests is 33849, which places it at the 78th percentile among all GPUs in the database.

The RX 7700S's nearest rivals in the database provide context. The AMD Radeon HD 7950 has an average score of 33951, which is 0.3% higher than the RX 7700S, a negligible difference. The AMD Radeon RX 480 has an average score of 33997, 0.4% higher. The NVIDIA GeForce GTX 1060 5 GB has an average score of 33694, which is 0.5% lower. The NVIDIA RTX A5000 has an average score of 33622, which is 0.7% lower. These deltas are all within one percentage point, meaning the RX 7700S sits in a tight performance cluster around the 33850-point mark.

The N1 16SM has no benchmark scores whatsoever. Its average benchmark score is zero, and its percentile is a placeholder 50. There are no nearest rivals listed for it, and no wins recorded for either GPU in head-to-head testing because no such tests exist. The data shows that the RX 7700S has verified performance across multiple API workloads, while the N1 16SM remains unmeasured.

Where Each One Wins

The AMD Radeon RX 7700S wins in every category where performance data exists. In FP32 compute, it delivers 20.48 TFLOPS, more than double the 9.609 TFLOPS of the N1 16SM. In FP16 compute, the RX 7700S delivers 40.96 TFLOPS versus 9.609 TFLOPS, a fourfold advantage. Pixel fill rate favors AMD at 160.0 GPixel/s versus 56.30 GPixel/s. Texture fill rate favors AMD at 320.0 GTexel/s versus 300.3 GTexel/s, a smaller but still positive margin. The RX 7700S has 64 ROPs versus 24, and 32 ray tracing cores versus 16. It also has a higher boost clock at 2500 MHz versus 2346 MHz, and a much higher base clock at 1500 MHz versus 741 MHz.

The NVIDIA N1 16SM wins in memory capacity, offering 128 GB versus 8 GB. It also has a wider 256-bit memory bus versus 128-bit, though its bandwidth is lower at 273.2 GB/s versus 288.0 GB/s. The N1 16SM has 64 tensor cores, which the RX 7700S lacks entirely. It uses a newer PCIe 5.0 x16 interface versus PCIe 4.0 x16. Its die is larger at 382 mm² versus 204 mm², and it uses a smaller 5 nm process versus 6 nm. The N1 16SM also has a later release date in the database.

For gaming workloads, the RX 7700S is the only GPU with DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists no API support. For compute workloads involving tensor operations, the N1 16SM has dedicated tensor cores, but no benchmark data confirms their performance. The recorded data shows the RX 7700S as the only GPU with validated scores across DirectX, OpenCL, and Vulkan. Users needing immediate, measurable graphics performance should select the RX 7700S. Users prioritizing memory capacity or tensor core availability may consider the N1 16SM, but its performance remains unverified in the database.
