AMD Radeon RX 7700 vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The AMD Radeon RX 7700 has a full set of benchmark results, while the NVIDIA N1X 48SM has no recorded benchmark scores in the database. The head-to-head benchmark array is empty, with winsA and winsB both at zero. This means there are no direct measurement comparisons available between these two parts.

The AMD Radeon RX 7700 shows an average benchmark score of 15852 across its tested workloads. Its performance distribution places it at the 58th percentile of all GPUs in the database. The NVIDIA N1X 48SM sits at the 50th percentile, but this figure is based on no recorded measurements; its average benchmark score is listed as zero.

Without direct head-to-head scores, the nearest rival data for the RX 7700 provides context. The RX 7700 trails the AMD Radeon RX 9060 by 1% (16014 vs 15852). It is 1.7% behind the NVIDIA GeForce RTX 3060 Ti, which scores 16129. Against the AMD Radeon Pro W5500, the RX 7700 leads by 1.1% (15679). The closest competitor is the AMD Radeon R9 370X, which scores 15862, a delta of -0.1%, effectively a statistical tie.

The N1X 48SM has no nearest rivals listed. Its database entry contains no benchmark tests, no percentile rivals, and no comparable scores. The only quantitative performance indicators are its raw compute specifications, not measured outcomes.

The RX 7700's individual test scores show a wide spread across APIs. In PassMark G3D, it records 20974, while its GPU compute score is 10963. The Geekbench OpenCL result is 106028. PassMark DirectX 11 returns 186, DirectX 9 returns 261, DirectX 10 returns 92, and DirectX 12 returns 96. The 3DMark Steel Nomad DX12 test yields 2865. The PassMark G2D score is 1206.

These scores cannot be compared to the N1X 48SM because the latter has no recorded data. Any statement about which part wins a given benchmark is impossible from the database. The comparison is therefore one of specifications and architecture, not measured performance.

The Verdict

The data indicates that the AMD Radeon RX 7700 is a fully characterized discrete graphics card with an active production status, a 200 W TDP, and a dual-slot cooler requiring two 8-pin power connectors. Its performance profile places it near the AMD Radeon RX 9060 and the NVIDIA GeForce RTX 3060 Ti, within a 1.7% band. This is a mid-pack result, reflected in its 58th percentile ranking.

The NVIDIA N1X 48SM is an integrated graphics processor (IGP) built on the Blackwell 2.0 architecture. It has no TDP listed, no power connectors, and no measured benchmarks. Its memory configuration is 128 GB of LPDDR5X, which is unusual and suggests a specialized or embedded platform rather than a consumer add-in board. Its PCIe 5.0 x16 interface and IGP slot width reinforce this interpretation.

From the recorded data, the RX 7700 is the only part with verifiable performance. It delivers 25.18 TFLOPS FP32, a texture rate of 393.4 GTexel/s, and a pixel rate of 236.1 GPixel/s. The N1X 48SM lists higher theoretical numbers: 28.83 TFLOPS FP32, 900.9 GTexel/s texture rate, but a lower pixel rate of 112.6 GPixel/s. However, without benchmark scores, these specifications do not translate into confirmed real-world results.

The verdict is straightforward: the RX 7700 is the only part with database-measured performance. The N1X 48SM cannot be assessed for gaming or compute workloads from the available evidence. A user choosing based on recorded data would select the RX 7700, as it has an active production status, a known TDP, and a set of benchmark results.

Where Each One Wins

The RX 7700 wins on any benchmark category where measurements exist. Its PassMark G3D score of 20974 and compute score of 10963 indicate a functional discrete GPU. Its 3DMark Steel Nomad result of 2865 confirms DirectX 12 capability. The RX 7700 also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which are standard for modern gaming workloads.

The N1X 48SM wins on theoretical specifications. It lists 6144 shading units versus 2560 for the RX 7700, 384 TMUs versus 160, and 192 tensor cores versus none for the AMD part. Its FP32 throughput of 28.83 TFLOPS exceeds the RX 7700's 25.18 TFLOPS. Its texture rate of 900.9 GTexel/s is more than double the RX 7700's 393.4 GTexel/s. It also has 48 RT cores versus 40 for the RX 7700.

The N1X 48SM has a memory capacity advantage: 128 GB of LPDDR5X versus 16 GB of GDDR6. However, its memory bandwidth is lower at 273.2 GB/s versus 624.1 GB/s. The RX 7700's 256-bit bus carries GDDR6 at 19.5 Gbps effective, while the N1X 48SM uses the same bus width with LPDDR5X at 8.5 Gbps effective.

The RX 7700 wins on bandwidth, pixel rate, and confirmed software API support. The N1X 48SM lists no DirectX, OpenGL, or Vulkan support in its database entry, which is a significant limitation for conventional gaming applications.
