AMD Radeon RX 7700 vs NVIDIA N1X 40SM Comparison

Where Each One Wins

The recorded data splits these two parts cleanly by intent. The AMD Radeon RX 7700 is a discrete graphics card with a full benchmark suite: nine separate tests covering DirectX 9 through DirectX 12, OpenCL compute, and 2D graphics. Its average benchmark score sits at 15,852, placing it in the 58th percentile of all GPUs in the database. The NVIDIA N1X 40SM, by contrast, is an integrated graphics processor (IGP) with zero recorded benchmarks and an average score of zero. It holds the 50th percentile by default, not by measured performance.

The use-case split is therefore stark. The RX 7700 wins every measurable workload because it is the only part with measurements. The N1X 40SM shows no wins in any test, simply because no test data exists. This does not mean the NVIDIA part is non-functional; it means the database contains no evidence of its performance. For any workload that appears in the benchmark list, the RX 7700 is the only part with a score to cite.

The RX 7700's benchmark profile shows particular strength in DirectX 11, where it scores 186, and in 3D graphics overall, where PassMark G3D returns 20,974. Its OpenCL score of 106,028 indicates substantial compute throughput. The DirectX 9 score of 261 and the DirectX 10 score of 92 complete the legacy API picture. The 2D score of 1,206 is the lowest of its results, which is typical for a card optimized for 3D rendering rather than desktop compositing.

For the N1X 40SM, the absence of benchmarks means its wins are structural rather than measured. It uses an IGP form factor with no power connectors and no suggested PSU, which makes it suitable for systems where a discrete card cannot be installed. It also supports PCIe 5.0 x16, a newer bus interface than the RX 7700's PCIe 4.0 x16. These are not performance wins; they are platform compatibility advantages that the data records but cannot quantify in frames per second or compute scores.

Architecture Differences

The two parts come from different architectural lineages. The RX 7700 uses the Navi 32 chip built on RDNA 3.0, with the codename Wheat Nas, and belongs to the Navi III (RX 7000) generation. The N1X 40SM uses the GB20B chip built on Blackwell 2.0, belongs to the Blackwell IGP (N1x) generation, and has no codename recorded. Both are fabricated by TSMC on a 5 nm process, so the manufacturing node is identical.

The transistor counts differ sharply. The RX 7700 packs 28,100 million transistors onto a 346 mm² die, giving a density of 81.2 million transistors per square millimeter. The N1X 40SM has an unknown transistor count but a larger die at 382 mm². With no transistor figure recorded, the density cannot be calculated. The die size difference of 36 mm² is modest, but the RX 7700 crams far more transistors into less space, which suggests a denser logic design.

The compute layouts diverge significantly. The RX 7700 has 2,560 shading units, 160 texture mapping units, 96 ROPs, and 40 ray tracing cores. The N1X 40SM has 5,120 shading units, 320 TMUs, 40 ROPs, and 40 ray tracing cores. The NVIDIA part has double the shading units and double the TMUs, but less than half the ROPs. It also adds 160 tensor cores, which the AMD part lacks entirely. These are architectural choices: AMD allocates more hardware to pixel output, NVIDIA allocates more to shader throughput and tensor operations.

Clock behavior also differs. The RX 7700 runs a base clock of 1900 MHz, a game clock of 2041 MHz, and a boost clock of 2459 MHz. The N1X 40SM starts much lower at 741 MHz base but boosts to 2346 MHz, which is close to the AMD boost. The memory clocks diverge even more: the RX 7700 runs memory at 2438 MHz for 19.5 Gbps effective, while the N1X 40SM runs at 1067 MHz for 8.5 Gbps effective. The AMD part is clocked far more aggressively in both compute and memory domains.

The memory subsystems reflect different priorities. The RX 7700 has 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The N1X 40SM has 128 GB of LPDDR5X on the same 256-bit bus, but only 273.2 GB/s of bandwidth. The capacity is eight times larger on the NVIDIA side, but the bandwidth is less than half. This indicates the N1X 40SM is built for capacity-bound workloads such as large model residency, while the RX 7700 targets bandwidth-bound rendering.

The API support also separates them. The RX 7700 lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists N/A for all three. This means the AMD part has explicit driver-level support for modern graphics APIs, while the NVIDIA part's API support is unrecorded or absent. For gaming or graphics workloads, this is a decisive difference.

The Verdict

The data points to a clear division of purpose. The RX 7700 is a discrete, actively produced graphics card with measured performance across nine benchmarks, a 58th percentile ranking, and an average score of 15,852. The N1X 40SM is an integrated processor with no benchmarks, no average score, and a 50th percentile that reflects absence of data rather than measured capability.

Any user seeking a part for rendering, gaming, or compute workloads that appear in the benchmark suite should select the RX 7700, because it is the only part with scores in those tests. The RX 7700 also has a 200 W TDP, dual-slot cooling, and two 8-pin power connectors, all of which indicate a conventional discrete card installation. It requires a 550 W suggested PSU and a PCIe 4.0 x16 slot.

The N1X 40SM suits systems where a discrete card cannot fit. Its IGP form factor, lack of power connectors, and 128 GB of memory point toward specialized or embedded use cases. The PCIe 5.0 x16 interface is a forward-looking choice. But with no benchmark scores, the database cannot confirm any performance advantage.

The nearest rivals for the RX 7700 provide context. The AMD Radeon R9 370X scores 15,862, which is 0.1% higher. The AMD Radeon RX 9060 scores 16,014, which is 1% higher. The AMD Radeon Pro W5500 scores 15,679, which is 1.1% lower. The NVIDIA GeForce RTX 3060 Ti scores 16,129, which is 1.7% higher. These deltas are all within a narrow band, indicating the RX 7700 sits in a tightly contested performance tier. The N1X 40SM has no rivals listed, so no such comparison is possible.

The verdict is not about which part is better in absolute terms. It is about which part has evidence of performance. The RX 7700 has that evidence. The N1X 40SM does not.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty. No shared tests exist between the two parts, so no direct comparison scores are recorded. The RX 7700's individual scores stand alone, and the N1X 40SM has no scores at all.

The largest wins for the RX 7700 are therefore implicit. In PassMark G3D, it scores 20,974. In Geekbench OpenCL, it scores 106,028. In 3DMark Steel Nomad DX12, it scores 2,865. In PassMark GPU Compute, it scores 10,963. These are the only numbers available, and they all belong to the AMD part.

The N1X 40SM cannot register any win because it has no data. The closest the database comes to a head-to-head is the RX 7700's nearest rivals, all of which are other discrete cards. The NVIDIA GeForce RTX 3060 Ti scores 16,129, which is 1.7% higher than the RX 7700's average. The AMD Radeon RX 9060 scores 16,014, 1% higher. The AMD Radeon R9 370X scores 15,862, 0.1% higher. The AMD Radeon Pro W5500 scores 15,679, 1.1% lower.

These deltas show the RX 7700 within 1.7% of the RTX 3060 Ti and within 1% of the RX 9060. The margin against the R9 370X is negligible at 0.1%. The only recorded rival that the RX 7700 beats is the Pro W5500. Every one of these comparisons uses average scores from the database, and none of them involve the N1X 40SM.
