AMD Radeon RX 9070 vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data shows a substantial performance gap between the AMD Radeon RX 9070 and the NVIDIA N1X 48SM, though the comparison is limited by the availability of measurements. The AMD Radeon RX 9070 has ten recorded benchmark scores across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads. The NVIDIA N1X 48SM has no recorded benchmark scores in the database, leaving its average benchmark score at 0.

The AMD Radeon RX 9070 posts an average benchmark score of 23877 across its suite of tests. Its percentile ranking among all GPUs is 69, placing it above the median. The NVIDIA N1X 48SM sits at the 50th percentile with no recorded scores, which means the database cannot currently establish any head-to-head wins for either part in direct benchmark comparisons. The head-to-head field is empty, and both win counters stand at zero.

The nearest rivals for the AMD Radeon RX 9070 provide context for its scoring. The NVIDIA GeForce RTX 2080 SUPER averages 24170, which is 1.2 percent higher than the RX 9070's average. The AMD Radeon RX 6800S averages 24063, 0.8 percent higher. The NVIDIA GeForce GTX TITAN Z averages 23736, 0.6 percent lower. The NVIDIA GeForce RTX 3080 Mobile averages 23628, 1.1 percent lower. These deltas indicate the RX 9070 sits within a tight cluster of previous-generation desktop and mobile parts, with no rival in its immediate vicinity exceeding a 1.2 percent difference.

Among its individual scores, the AMD Radeon RX 9070 delivers its strongest result in the Geekbench OpenCL test with 131539 points. The Geekbench Vulkan score reaches 58705. In the Passmark suite, the GPU compute score is 14737, the G3D score is 25381, and the G2D score is 1280. Legacy DirectX tests show 343 in DirectX 9, 281 in DirectX 11, 141 in DirectX 10, and 74 in DirectX 12. The 3DMark Steel Nomad DX12 score is 6290. These figures establish the RX 9070 as a capable performer across both modern and legacy workloads.

Because the NVIDIA N1X 48SM lacks any benchmark entries, no direct score comparisons can be drawn. The database shows the N1X 48SM with zero recorded average score and no rival list. This absence of data means the analysis must rely on architectural specifications to differentiate the two products.

Where Each One Wins

The AMD Radeon RX 9070 wins in every category where measurements exist. It has recorded scores in ten separate benchmarks, covering three major test suites: 3DMark, Geekbench, and Passmark. Its 69th percentile ranking among all GPUs confirms that it outperforms a majority of the database's tracked graphics processors. The NVIDIA N1X 48SM, by contrast, has no scores in any benchmark, placing it at the 50th percentile by default and giving it no measurable wins.

For users running DirectX 9, 10, 11, or 12 titles, the RX 9070 offers recorded scores across all four API levels. The Passmark DirectX 9 score of 343 is the highest of its legacy results, while the DirectX 12 score of 74 is the lowest. This suggests the RX 9070 handles older APIs particularly well relative to its own results, though the absolute values across these tests should be interpreted within the context of each benchmark's scaling.

OpenCL and Vulkan workloads also favor the RX 9070, with Geekbench scores of 131539 and 58705 respectively. These figures indicate strong compute throughput for general-purpose GPU tasks and cross-platform graphics. The Passmark GPU compute score of 14737 reinforces the compute-oriented strengths of the part.

The NVIDIA N1X 48SM wins only in the absence of data, which is not a meaningful victory. No benchmark results exist to establish a use case where it outperforms the RX 9070. The database records no wins for either side in head-to-head testing, so the practical takeaway is that the RX 9070 is the only one of the two with verified performance data.

Architecture Differences

The two products differ fundamentally in their underlying designs. The AMD Radeon RX 9070 uses the Navi 48 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. The die measures 357 mm² and contains 53,900 million transistors, yielding a transistor density of 151.0 million per mm². The NVIDIA N1X 48SM uses the GB20B chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. Its die measures 382 mm², though its transistor count is listed as unknown.

Clock speeds show notable differences. The RX 9070 has a base clock of 1330 MHz, a boost clock of 2520 MHz, and a game clock of 2070 MHz. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz, with no game clock specified. The RX 9070 runs its memory at 2518 MHz, translating to 20.1 Gbps effective, while the N1X 48SM runs memory at 1067 MHz, or 8.5 Gbps effective.

Memory configurations diverge sharply. The RX 9070 carries 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The N1X 48SM carries 128 GB of LPDDR5X on a 256-bit bus, but bandwidth is only 273.2 GB/s. The N1X 48SM has eight times the capacity but less than half the bandwidth.

Compute resources also differ. The RX 9070 has 3584 shading units, 224 texture mapping units, 128 render output units, and 56 ray tracing cores. It has no tensor cores listed. The N1X 48SM has 6144 shading units, 384 texture mapping units, 48 render output units, 48 ray tracing cores, and 192 tensor cores. The N1X 48SM has more shading units and texture units, but fewer render output units.

Rates and throughput figures reflect these configurations. The RX 9070 achieves a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s. The N1X 48SM achieves 112.6 GPixel/s and 900.9 GTexel/s. Floating point performance shows the RX 9070 at 36.13 TFLOPS for both FP32 and FP16, while the N1X 48SM delivers 28.83 TFLOPS for both. The RX 9070 leads in pixel rate and FP32, while the N1X 48SM leads in texture rate.

API support differs completely. The RX 9070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This is a decisive difference for gaming and general graphics applications, as the RX 9070 supports all major contemporary APIs while the N1X 48SM records none.

Power and physical specifications also diverge. The RX 9070 has a TDP of 220 W, uses dual-slot cooling, requires two 8-pin power connectors, and suggests a 550 W power supply. The N1X 48SM has an unknown TDP, is an IGP (integrated graphics processor) with no slot width, uses no power connectors, and lists no suggested power supply. The RX 9070 is a discrete add-in board, while the N1X 48SM is designed for integration.

Display outputs differ as well. The RX 9070 provides 1x HDMI 2.1b and 3x DisplayPort 2.1a. The N1X 48SM provides only 1x HDMI with no version specified. Both use a PCIe 5.0 x16 bus interface.

The RX 9070 was released on March 5, 2025, with a launch MSRP of 549 USD. The N1X 48SM has a release date of May 31, 2026, and no launch MSRP recorded. The RX 9070 succeeds the Navi III generation, while the N1X 48SM has no predecessor listed. Both are marked as active in production.

The Verdict

The data points to a clear choice for most users. The AMD Radeon RX 9070 has verified performance across ten benchmarks, a 69th percentile ranking, and an average score of 23877. The NVIDIA N1X 48SM has no recorded benchmarks, no average score, and a default 50th percentile. Any user requiring measured graphics performance should select the RX 9070 based on the available evidence.

The RX 9070 also offers broader software compatibility. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1X 48SM lists no supported APIs. For gaming, content creation, or compute workloads that rely on these APIs, the RX 9070 is the only viable option in this comparison.

The N1X 48SM does have advantages in specific hardware specifications. It offers 128 GB of memory versus 16 GB, 6144 shading units versus 3584, 192 tensor cores versus none, and a higher texture rate of 900.9 GTexel/s versus 564.5 GTexel/s. These specifications suggest potential strengths in memory-heavy or tensor-focused workloads, but without benchmark data, those strengths remain unverified.

The RX 9070 counters with higher clock speeds, more memory bandwidth, higher pixel rate, and higher FP32 throughput. Its 644.6 GB/s of bandwidth versus 273.2 GB/s gives it a substantial advantage in bandwidth-bound scenarios. Its 36.13 TFLOPS FP32 exceeds the N1X 48SM's 28.83 TFLOPS by roughly 25 percent.

For users building a discrete graphics system, the RX 9070 is the rational choice. It has proven performance, a defined power envelope of 220 W, standard display outputs, and broad API support. The N1X 48SM may serve a niche role as an integrated processor with large memory capacity, but the database currently provides no evidence of its real-world performance.
