AMD Radeon RX 7600M XT vs NVIDIA N1X 40SM Comparison

Where Each One Wins

The recorded data presents an unusual comparison, as the two GPUs occupy different positions in the benchmark landscape. The AMD Radeon RX 7600M XT has a full suite of measured scores across ten tests, while the NVIDIA N1X 40SM has no recorded benchmark results in the database. This means the AMD part wins every measurable benchmark category by default, but that is a function of data availability rather than a direct performance verdict.

The AMD Radeon RX 7600M XT shows its strengths across DirectX workloads, with PassMark scores of 175 in DirectX 9, 137 in DirectX 11, and 58 in DirectX 12. Its strongest showing comes in the 3DMark Steel Nomad DX12 test, where it records a score of 2048. In compute-oriented workloads, the GPU delivers a Geekbench OpenCL score of 74869 and a PassMark GPU compute score of 7140. The Vulkan API performance is also solid, with a Geekbench Vulkan score of 27793.

The NVIDIA N1X 40SM, by contrast, has no benchmark entries listed. Its average benchmark score sits at 0, and its percentile versus all GPUs is 50, which places it at the midpoint of the database distribution despite having no measured performance data. This is an anomaly in the database, as the percentile field suggests a mid-pack positioning, but the absence of scores means no use-case wins can be attributed to it.

For practical purposes, the AMD Radeon RX 7600M XT wins wherever a workload requires established DirectX or Vulkan support, and it also leads in OpenCL compute tasks. The NVIDIA part cannot be assigned any wins from the recorded data. Users seeking a GPU with verified performance in existing APIs should consider the AMD part, while the NVIDIA N1X 40SM remains an untested quantity in the database.

Architecture Differences

The two GPUs come from fundamentally different architectures and process nodes. The AMD Radeon RX 7600M XT uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It is fabricated on a 6 nm process at TSMC, with a die size of 204 mm² and 13,300 million transistors. The transistor density works out to 65.2 million per square millimeter.

The NVIDIA N1X 40SM uses the GB20B chip built on Blackwell 2.0 architecture. It is fabricated on a 5 nm process at TSMC, with a die size of 382 mm². The transistor count is listed as unknown, and there is no transistor density figure recorded. The process node advantage goes to NVIDIA at 5 nm versus 6 nm, but the AMD chip is substantially smaller in die area.

The AMD GPU features 2048 shading units, 128 texture mapping units, and 64 render output units. It has 32 ray tracing cores and no tensor cores. The NVIDIA part offers 5120 shading units, 320 texture mapping units, and 40 render output units. It has 40 ray tracing cores and 160 tensor cores. The NVIDIA GPU has more than double the shading units and more than double the texture units, but fewer render output units than the AMD part.

Memory architecture differs significantly. The AMD Radeon RX 7600M XT uses 8 GB of GDDR6 memory on a 128 bit bus, with a bandwidth of 288.0 GB/s. The NVIDIA N1X 40SM uses 128 GB of LPDDR5X memory on a 256 bit bus, with a bandwidth of 273.2 GB/s. The NVIDIA part has a much larger memory capacity, but slightly lower bandwidth despite the wider bus.

Clock speeds show different design priorities. The AMD GPU has a base clock of 1280 MHz and a boost clock of 2469 MHz, with a game clock of 2023 MHz. Memory runs at 2250 MHz or 18 Gbps effective. The NVIDIA part has a base clock of 741 MHz and a boost clock of 2346 MHz, with memory at 1067 MHz or 8.5 Gbps effective. The AMD GPU has higher base and boost clocks, plus faster memory clocks.

The bus interface also differs. AMD uses PCIe 4.0 x16, while NVIDIA uses PCIe 5.0 x16. Both are integrated graphics packages (IGP) with no power connectors and no slot width beyond the integrated form factor.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, meaning there are no direct comparison scores between the AMD Radeon RX 7600M XT and the NVIDIA N1X 40SM. The only available data for the AMD part comes from its individual benchmark entries, while the NVIDIA part has none.

The AMD Radeon RX 7600M XT delivers a 3DMark Steel Nomad DX12 score of 2048. Its Geekbench OpenCL score is 74869, and its Geekbench Vulkan score is 27793. In PassMark tests, the DirectX 10 score is 76, DirectX 11 is 137, DirectX 12 is 58, and DirectX 9 is 175. The G2D score is 894, G3D is 13907, and GPU compute is 7140.

With no NVIDIA scores to compare, the relative performance cannot be quantified. The AMD part's average benchmark score is 12710, which places it at the 52nd percentile of all GPUs in the database. Its nearest rivals include the NVIDIA GeForce GTX 670 with an average score of 12773 and a delta of -0.5%, the NVIDIA Tesla K20Xm with 12625 and a delta of 0.7%, the NVIDIA GeForce GTX 590 with 12830 and a delta of -0.9%, and the AMD Radeon Pro 455 with 12831 and a delta of -0.9%. This indicates the AMD part sits within a tight cluster of older high-end desktop GPUs, roughly 1% above or below each rival.

The NVIDIA N1X 40SM has an average benchmark score of 0 and no nearest rivals listed. Its percentile of 50 places it at the median of the database distribution, but without any measured scores this is not supported by performance data.

The Verdict

The data supports a clear division. The AMD Radeon RX 7600M XT has verified performance across a range of DirectX, Vulkan, and OpenCL workloads, with an average benchmark score of 12710 and a 52nd percentile placement among all GPUs. Its nearest rivals are all within 1% of its average score, confirming it sits in a well-established performance tier.

The NVIDIA N1X 40SM has no benchmark scores recorded. Its percentile of 50 suggests a mid-pack placement in the database, but this is not backed by any measured performance data. Its architecture shows significant theoretical advantages: more shading units, more texture units, more ray tracing cores, tensor cores, a larger memory pool, and higher FP32 compute. The 5 nm process node and PCIe 5.0 interface also point to a newer design.

For users who need a GPU with demonstrated performance in current APIs, the AMD Radeon RX 7600M XT is the only option with recorded data. It delivers competitive scores against older NVIDIA and AMD desktop parts, and its 120 W power draw is a known quantity.

For users evaluating the NVIDIA N1X 40SM, the database offers no performance evidence. The specification sheet suggests a capable compute device with large memory capacity and tensor core support, but without benchmark results, its real-world behavior cannot be assessed. The absence of DirectX, OpenGL, and Vulkan API support in the database further limits its applicability for gaming workloads.

The choice depends on whether verified performance or theoretical specifications matter more. The AMD part wins on measured results. The NVIDIA part wins on paper specifications, but no data confirms how those specifications translate into actual performance.
