AMD Radeon RX 9070 XT vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data contains benchmark results for the AMD Radeon RX 9070 XT, while the NVIDIA N1X 40SM has no benchmark entries in the database. This makes a direct score comparison impossible. The AMD Radeon RX 9070 XT delivers an average benchmark score of 13543 across all recorded tests. Its percentile ranking against all GPUs is 55, while the NVIDIA N1X 40SM sits at percentile 50 with an average score of 0.

The nearest rivals to the AMD Radeon RX 9070 XT provide context for its performance tier. The AMD Radeon HD 7770M averages 13536, a delta of 0.1 percent. The NVIDIA GeForce GTX 570 averages 13515, a delta of 0.2 percent. The NVIDIA P106-090 averages 13470, a delta of 0.5 percent. The AMD Radeon Pro 555 averages 13407, a delta of 1 percent. These deltas are all positive, meaning the RX 9070 XT leads each of these four rivals by a narrow margin.

The RX 9070 XT scores 7260 in 3DMark Steel Nomad DX12. In Geekbench OpenCL it records 17428, while Geekbench Vulkan reaches 65879. Passmark results include DirectX 9 at 353, DirectX 10 at 154, DirectX 11 at 292, and DirectX 12 at 78. The Passmark G2D score is 1328, G3D is 26795, and GPU Compute is 15864. These figures establish a baseline for the RX 9070 XT within the database, but no corresponding figures exist for the N1X 40SM.

Because the N1X 40SM lacks recorded benchmark scores, the head-to-head comparison rests on architectural and specification differences rather than measured performance. The data shows a clear disparity in expected compute capability. The RX 9070 XT delivers 48.66 TFLOPS FP32, exactly double the 24.02 TFLOPS of the N1X 40SM. The pixel rate tells a similar story: 380.2 GPixel/s versus 93.84 GPixel/s. Texture rate is nearly identical, with 760.3 GTexel/s for AMD and 750.7 GTexel/s for NVIDIA.

Where Each One Wins

The AMD Radeon RX 9070 XT wins in raw compute throughput. Its FP32 figure of 48.66 TFLOPS is double the N1X 40SM's 24.02 TFLOPS. The FP16 figures match the FP32 figures on both parts, each at a 1:1 ratio, so the same doubling applies. Pixel fill rate favors AMD by a wide margin, 380.2 GPixel/s against 93.84 GPixel/s. Memory bandwidth also favors AMD: 644.6 GB/s versus 273.2 GB/s, a difference driven by GDDR6 at 20.1 Gbps effective versus LPDDR5X at 8.5 Gbps effective.

The NVIDIA N1X 40SM wins in shading unit count, with 5120 shading units against 4096. It also has more texture mapping units, 320 versus 256. Tensor cores exist only on the NVIDIA side at 160, while the AMD part has no tensor core field populated. The N1X 40SM carries 128 GB of LPDDR5X memory, which is 8 times the 16 GB on the RX 9070 XT, though at lower bandwidth.

The AMD part wins on clock speeds. Base clock is 1660 MHz versus 741 MHz, and boost clock is 2970 MHz versus 2346 MHz. The RX 9070 XT also has a defined game clock of 2400 MHz, while the N1X 40SM has no game clock recorded. The AMD card uses a 304 W TDP and requires a 700 W suggested PSU, whereas the N1X 40SM has no TDP or PSU figure recorded. The AMD card is dual-slot with two 8-pin power connectors; the N1X 40SM is an integrated graphics processor with no power connectors.

Architecture Differences

The AMD Radeon RX 9070 XT uses the Navi 48 chip built on RDNA 4.0 architecture. The process node is 4 nm at TSMC. The transistor count is 53,900 million on a die size of 357 mm², giving a transistor density of 151.0 million per square millimeter. The NVIDIA N1X 40SM uses the GB20B chip on Blackwell 2.0 architecture. Its process node is 5 nm at TSMC, one step larger than the AMD part. The die size is 382 mm², slightly larger than AMD's, but the transistor count is listed as unknown, so density cannot be calculated.

Memory architecture differs substantially. The RX 9070 XT uses 16 GB of GDDR6 on a 256 bit bus at 2518 MHz, producing 644.6 GB/s. The N1X 40SM uses 128 GB of LPDDR5X on a 256 bit bus at 1067 MHz, producing 273.2 GB/s. Both use the same bus width, but the memory type, capacity, and effective data rate differ. The AMD memory clock runs at 20.1 Gbps effective, while the NVIDIA memory runs at 8.5 Gbps effective.

Ray tracing hardware differs. The RX 9070 XT has 64 RT cores, while the N1X 40SM has 40 RT cores. The N1X 40SM has 160 tensor cores; no tensor core count is listed for the RX 9070 XT. Render output units differ significantly: 128 ROPs on AMD versus 40 on NVIDIA. The shading unit count favors NVIDIA at 5120 versus 4096, and TMUs favor NVIDIA at 320 versus 256.

API support is a major differentiator. The RX 9070 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This indicates the NVIDIA part does not expose standard desktop graphics APIs in the recorded data. The RX 9070 XT also offers 1x HDMI 2.1b and 3x DisplayPort 2.1a outputs, while the N1X 40SM lists only 1x HDMI.

The AMD card belongs to the Radeon RX 9000 series and the Navi IV (RX 9000) generation, with a predecessor of Navi III. The NVIDIA part belongs to the Blackwell IGP (N1x) generation, with no predecessor listed. Release dates differ: the RX 9070 XT launched on 2025-03-05, while the N1X 40SM has a release date of 2026-05-31. The AMD card has a launch MSRP of 599 USD.

The Verdict

The data supports the AMD Radeon RX 9070 XT for any workload that depends on standard graphics APIs, raw FP32 throughput, pixel fill rate, or memory bandwidth. It has double the FP32 compute, roughly 4 times the pixel rate, and more than double the memory bandwidth. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which makes it suitable for conventional desktop rendering workloads. Its 55th percentile ranking and average score of 13543 place it above all four recorded nearest rivals.

The NVIDIA N1X 40SM is an integrated graphics processor with no recorded benchmark scores, no API support, and no TDP data. Its advantages are limited to specific hardware features: 5120 shading units, 320 TMUs, 160 tensor cores, and 128 GB of memory capacity. The 128 GB capacity could matter for memory-bound tasks that fit within a 256 bit bus, but the 273.2 GB/s bandwidth limits that capacity. The N1X 40SM has no power connectors and occupies an IGP slot, which suggests a different deployment context than a dual-slot add-in card.

For gaming and general GPU compute, the RX 9070 XT is the only option with measured performance data. The N1X 40SM cannot be compared on benchmark scores because none exist in the database. The RX 9070 XT also has a higher boost clock, 2970 MHz versus 2346 MHz, and a defined game clock of 2400 MHz. The lack of API support on the N1X 40SM makes it unsuitable for standard DirectX or Vulkan applications.
