AMD Radeon RX 7700 vs NVIDIA N1 16SM Comparison

The Verdict

The recorded data presents a stark contrast between two very different products. The AMD Radeon RX 7700 is a conventional, active discrete graphics card with a substantial benchmark footprint, while the NVIDIA N1 16SM is an integrated graphics processor (IGP) with no recorded benchmark scores in the database. For any task requiring measurable graphics performance, the RX 7700 is the only viable option based on available measurements. The N1 16SM, despite its newer architecture and massive memory allocation, offers no verified performance data, making it impossible to recommend for any workload where rasterization, compute, or DirectX performance is required. The RX 7700 sits in the 58th percentile of all GPUs, while the N1 16SM sits in the 50th percentile, though that percentile for the N1 is based on no recorded average score, which limits its analytical usefulness.

Architecture Differences

The two chips come from different architectural lineages. The AMD Radeon RX 7700 uses the Navi 32 chip built on RDNA 3.0 architecture, belonging to the Navi III (RX 7000) generation with the codename "Wheat Nas." The NVIDIA N1 16SM uses the GB20B chip built on Blackwell 2.0 architecture, belonging to the Blackwell IGP (N1x) generation. Both are fabricated on a 5 nm process at TSMC, but the similarities end there. The AMD chip contains 28,100 million transistors on a 346 mm² die, resulting in a transistor density of 81.2M per mm². The NVIDIA chip's transistor count is unknown, though its die size is listed at 382 mm², which is slightly larger than the AMD die.

Memory configurations diverge dramatically. The RX 7700 uses 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus, but only achieves 273.2 GB/s of bandwidth. The N1's memory clock is 1067 MHz (8.5 Gbps effective), compared to the RX 7700's 2438 MHz (19.5 Gbps effective). Despite having eight times the capacity, the N1's bandwidth is less than half that of the RX 7700, which indicates a significant memory throughput disadvantage.

Compute resources also differ. The RX 7700 has 2560 shading units, 160 texture mapping units, and 96 ROPs. The N1 16SM has 2048 shading units, 128 TMUs, and only 24 ROPs. The RX 7700 includes 40 ray tracing cores; the N1 includes 16 RT cores and 64 tensor cores. The RX 7700 has no tensor cores listed. The RX 7700's FP32 performance is 25.18 TFLOPS with matching FP16 at a 1:1 ratio. The N1 16SM delivers 9.609 TFLOPS FP32 and FP16, which is roughly 38% of the AMD card's compute throughput.

Clock speeds reveal part of the story. The RX 7700 runs at a base clock of 1900 MHz, a game clock of 2041 MHz, and a boost clock of 2459 MHz. The N1 16SM runs at a base clock of 741 MHz and a boost clock of 2346 MHz. The N1's boost clock is only slightly lower than the RX 7700's, but its base clock is substantially lower, suggesting a wider power and thermal envelope for the AMD part.

The RX 7700 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This means the N1 has no recorded API compatibility for standard graphics workloads, which is a critical limitation. The RX 7700 uses a PCIe 4.0 x16 interface and requires a 550 W suggested power supply with two 8-pin connectors. The N1 uses PCIe 5.0 x16 and has no power connectors, consistent with its IGP classification. The RX 7700 is a dual-slot card measuring 267 mm in length, 135 mm in height, and 50 mm in width, with display outputs of one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C. The N1 has a single HDMI output.

Where Each One Wins

Based strictly on recorded data, the AMD Radeon RX 7700 wins every measurable category. It has higher pixel rate (236.1 GPixel/s versus 56.30 GPixel/s), higher texture rate (393.4 GTexel/s versus 300.3 GTexel/s), and higher FP32 throughput. The RX 7700 has more shading units, more TMUs, more ROPs, and more RT cores. Its memory bandwidth advantage is substantial at 624.1 GB/s versus 273.2 GB/s.

The NVIDIA N1 16SM wins in memory capacity with 128 GB versus 16 GB, which could theoretically benefit workloads that need to hold extremely large datasets in local memory. It also has 64 tensor cores, which the RX 7700 lacks entirely, indicating a potential advantage for AI or machine learning inference workloads, though no benchmark data confirms this. The N1 also uses a newer PCIe 5.0 x16 interface versus the RX 7700's PCIe 4.0 x16. The N1 is an IGP with no power connectors, which means it requires no separate power delivery and could be suitable for compact systems, but the RX 7700's 200 W TDP and dual-slot design are typical for a performance discrete card.

The RX 7700 has nine recorded benchmark scores across multiple test suites. Its strongest results include a PassMark G3D score of 20974, a Geekbench OpenCL score of 106028, and a 3DMark Steel Nomad DX12 score of 2865. It also records PassMark GPU Compute at 10963, PassMark DirectX 11 at 186, PassMark DirectX 9 at 261, PassMark DirectX 10 at 92, PassMark DirectX 12 at 96, and PassMark G2D at 1206. The N1 16SM has no recorded benchmarks, so no direct comparison can be made.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two products, and the N1 16SM has no individual benchmark scores recorded. The comparison therefore relies on the RX 7700's measured performance and the N1's architectural specifications.

The RX 7700's largest measured wins come from its compute and rasterization scores. Its Geekbench OpenCL score of 106028 reflects strong general-purpose compute capability. Its PassMark G3D score of 20974 places it above several rivals in the database. Its 3DMark Steel Nomad DX12 score of 2865 confirms modern DirectX 12 performance. The PassMark DirectX 11 score of 186 and DirectX 12 score of 96 show legacy and current API performance, while the DirectX 9 score of 261 and DirectX 10 score of 92 cover older workloads.

The N1 16SM's only listed advantages are architectural. Its 128 GB memory capacity is the largest in this comparison, and its 64 tensor cores provide a resource the RX 7700 does not have. Its boost clock of 2346 MHz is close to the RX 7700's 2459 MHz boost, but its base clock of 741 MHz is far lower. Its pixel rate of 56.30 GPixel/s and texture rate of 300.3 GTexel/s are both below the RX 7700's respective rates of 236.1 GPixel/s and 393.4 GTexel/s.

The RX 7700's nearest rival data provides context for its standing. Its average score of 15852 is effectively tied with the R9 370X at a delta of -0.1%. It trails the RX 9060 by 1% and the RTX 3060 Ti by 1.7%. It leads the Pro W5500 by 1.1%. This places the RX 7700 in a competitive mid-range segment. The N1 16SM has no nearest rival data and no average score, so its standing cannot be quantified.

The RX 7700's transistor density of 81.2M per mm² on a 346 mm² die contrasts with the N1's unknown transistor count on a 382 mm² die. The RX 7700 achieves its performance with 28,100 million transistors, while the N1's transistor budget remains unlisted. The N1's memory clock of 1067 MHz is less than half the RX 7700's 2438 MHz, which explains the bandwidth gap despite identical bus widths.

Release timing also differs. The RX 7700 has a release date of September 17, 2025, with a predecessor in Navi II and a successor in Navi IV. The N1 16SM has a release date of May 31, 2026, with no predecessor or successor listed. Both are marked as active in production status. The RX 7700 is a dual-slot card with a 200 W TDP; the N1 is an IGP with no slot width beyond the IGP designation and an unknown TDP.

The RX 7700's 16 GB GDDR6 memory operates at 19.5 Gbps effective, producing 624.1 GB/s. The N1's 128 GB LPDDR5X operates at 8.5 Gbps effective, producing 273.2 GB/s. The RX 7700's ROP count of 96 versus the N1's 24 ROPs explains the large pixel rate difference. The RX 7700's TMU count of 160 versus the N1's 128 explains part of the texture rate gap, though the clock speed difference also contributes.

For software compatibility, the RX 7700 supports a full modern API stack. The N1 lists no API support, which means no DirectX, OpenGL, or Vulkan workloads can be confirmed from the data. The RX 7700's display outputs include HDMI 2.1a, two DisplayPort 2.1, and USB Type-C, while the N1 lists only a single HDMI. The RX 7700's PCIe 4.0 x16 interface is one generation older than the N1's PCIe 5.0 x16, but no benchmark data exists to show whether the newer interface provides any measurable benefit.

The database records the RX 7700 at the 58th percentile of all GPUs and the N1 16SM at the 50th percentile. With no average score for the N1, that percentile is based on no measured performance data. The RX 7700's average benchmark score of 15852 is the only verifiable aggregate performance figure in this comparison.
