AMD Radeon RX 9070 XT vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Radeon RX 9070 XT versus the NVIDIA N1X 48SM. The head-to-head array is empty, and neither part registers a win in a shared test. However, the AMD Radeon RX 9070 XT carries a full suite of ten individual benchmark results, while the NVIDIA N1X 48SM has no recorded scores in any test. This absence of overlapping data means a direct numeric comparison of rendering performance cannot be established from the database.

The AMD Radeon RX 9070 XT delivers a 3DMark Steel Nomad DX12 score of 7260, which represents its strongest single-test result. In Geekbench Vulkan, it records 65879, and in Geekbench OpenCL it scores 17428. Passmark results show 26795 in G3D, 15864 in GPU Compute, 1328 in G2D, 353 in DirectX 9, 292 in DirectX 11, 154 in DirectX 10, and 78 in DirectX 12. Its average benchmark score across these entries sits at 13543, placing it at the 55th percentile among all GPUs in the database. The NVIDIA N1X 48SM, by contrast, has an average benchmark score of 0 and sits at the 50th percentile, a position that reflects no recorded test data rather than a measured performance level.

The nearest recorded rivals for the AMD part illustrate its standing. The AMD Radeon HD 7770M averages 13536, which is 0.1% lower. The NVIDIA GeForce GTX 570 averages 13515, 0.2% lower. The NVIDIA P106-090 averages 13470, 0.5% lower. The AMD Radeon Pro 555 averages 13407, 1% lower. These deltas confirm that the Radeon RX 9070 XT edges out each of these four parts by a narrow margin in average score, but the comparisons are close, all within a 1% spread. The NVIDIA N1X 48SM has no nearest rivals listed, so no similar relational analysis is possible for that part.

Where Each One Wins

The AMD Radeon RX 9070 XT wins in pure rasterization throughput based on its recorded specifications. Its FP32 compute of 48.66 TFLOPS is higher than the NVIDIA N1X 48SM's 28.83 TFLOPS. Its pixel rate of 380.2 GPixel/s exceeds the NVIDIA part's 112.6 GPixel/s. Its memory bandwidth of 644.6 GB/s is more than double the NVIDIA part's 273.2 GB/s. Its boost clock of 2970 MHz is higher, and its base clock of 1660 MHz is more than double the NVIDIA part's 741 MHz. The AMD part also holds the advantage in API compatibility, supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the NVIDIA part lists these as N/A.

The NVIDIA N1X 48SM wins in several specification categories. It has 6144 shading units versus 4096, 384 texture mapping units versus 256, and 192 tensor cores versus none recorded. Its texture rate of 900.9 GTexel/s is higher than the AMD part's 760.3 GTexel/s. Its memory capacity of 128 GB is eight times the AMD part's 16 GB. Its die size of 382 mm² is larger than the AMD part's 357 mm². The NVIDIA part also uses an IGP form factor with no power connectors, which indicates a different physical integration approach than the AMD part's dual-slot, 2x 8-pin design.

For workloads that depend on FP32 compute, pixel fill, memory bandwidth, and high clock speeds, the data favors the AMD Radeon RX 9070 XT. For workloads that depend on shading unit count, texture throughput, tensor operations, and large memory capacity, the data favors the NVIDIA N1X 48SM. The NVIDIA part's 128 GB of LPDDR5X memory stands out as its most distinctive advantage, offering far more capacity than the AMD part's 16 GB, though at lower bandwidth.

The Verdict

The recorded data presents a clear split. The AMD Radeon RX 9070 XT is the stronger choice for conventional GPU workloads that rely on FP32 compute, pixel fill, memory bandwidth, and modern API support. Its 48.66 TFLOPS FP32 rating, 380.2 GPixel/s pixel rate, 644.6 GB/s bandwidth, and DirectX 12 Ultimate support position it as a fully featured discrete graphics solution. Its ten recorded benchmark scores, including a 3DMark Steel Nomad DX12 result of 7260 and a Geekbench Vulkan score of 65879, provide measurable evidence of its performance. Its average benchmark score of 13543 places it slightly above four nearest rivals, all within a 1% margin.

The NVIDIA N1X 48SM is the better fit for scenarios where memory capacity and compute unit count matter most. Its 128 GB of LPDDR5X memory is the largest capacity in this comparison by a wide margin. Its 6144 shading units and 384 texture mapping units exceed the AMD part, and its 192 tensor cores add a capability the AMD part does not list. Its texture rate of 900.9 GTexel/s is also higher. However, the absence of any recorded benchmark scores for the NVIDIA part means its real-world performance cannot be verified from the database.

The database shows zero head-to-head benchmark entries and zero wins for either part. No direct performance comparison is possible. The AMD Radeon RX 9070 XT has a 55th percentile ranking among all GPUs, while the NVIDIA N1X 48SM sits at the 50th percentile, but that ranking reflects no recorded test data. The AMD part has a launch MSRP of 599 USD; the NVIDIA part has none recorded. The AMD part is an active discrete GPU with a full specification sheet, while the NVIDIA part is an active IGP with several unknown fields, including transistor count, TDP, and all API support. The data supports the AMD Radeon RX 9070 XT for users prioritizing measured performance and standard feature support, and the NVIDIA N1X 48SM for users prioritizing memory capacity, shading unit count, and tensor hardware in an integrated form factor.
