AMD Radeon RX 9070 GRE vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The AMD Radeon RX 9070 GRE and the NVIDIA N1X 40SM occupy very different positions in the database, and the recorded measurements reflect that divide. The RX 9070 GRE posts a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. The N1X 40SM has no recorded benchmark entries, so direct head-to-head scores are unavailable. The database instead tracks average benchmark scores and percentile placement, which shows the gap between these two parts.

The RX 9070 GRE sits in the 87th percentile among all GPUs, with an average benchmark score of 57367. The N1X 40SM sits in the 50th percentile, with an average benchmark score of 0, meaning no completed tests have been logged. The RX 9070 GRE has four nearest rivals in the database: the Intel Arc A580 at 57756, the AMD Radeon RX 5600 OEM at 58085, the Intel Arc A570M at 58239, and the AMD Radeon RX 6950 XT at 58392. The RX 9070 GRE trails each of these by narrow margins, with deltas of -0.7%, -1.2%, -1.5%, and -1.8% respectively. Those are close results, indicating the RX 9070 GRE clusters tightly with that group in aggregate scoring rather than pulling ahead or falling behind by a large margin.

The N1X 40SM has no nearest rival entries and no average score, so the database cannot compute its relative standing beyond the 50th percentile marker. That percentile places it at the median of all recorded GPUs, but the lack of completed benchmarks makes any comparison provisional. In practical terms, the RX 9070 GRE delivers measurable results across both DX12 and OpenCL workloads, while the N1X 40SM has no comparable figures in the database.

Architecture Differences

The architectural split is substantial. The AMD Radeon RX 9070 GRE uses the Navi 48 chip on RDNA 4.0 architecture, built on a 4 nm process at TSMC. The NVIDIA N1X 40SM uses the GB20B chip on Blackwell 2.0 architecture, built on a 5 nm process, also at TSMC. The RX 9070 GRE packs 53,900 million transistors on a 357 mm² die, giving a transistor density of 151.0M per mm². The N1X 40SM die is larger at 382 mm², but its transistor count is listed as unknown, so a density figure cannot be computed.

The compute resources diverge sharply. The RX 9070 GRE has 3072 shading units, 192 texture mapping units, and 96 raster operating units. The N1X 40SM has 5120 shading units, 320 TMUs, and only 40 ROPs. The ray tracing configuration differs as well: the RX 9070 GRE carries 48 RT cores, while the N1X 40SM has 40 RT cores. The N1X 40SM also includes 160 tensor cores, a feature the RX 9070 GRE does not list. Clock speeds tell a different story. The RX 9070 GRE runs at a 1420 MHz base clock, a 2790 MHz boost clock, and a 2220 MHz game clock. The N1X 40SM runs at a 741 MHz base clock and a 2346 MHz boost clock, with no game clock listed. The RX 9070 GRE boosts substantially higher, which explains some of its throughput advantages despite fewer shading units.

Memory configurations are also far apart. The RX 9070 GRE uses 12 GB of GDDR6 on a 192-bit bus, with memory clocked at 2250 MHz for 18 Gbps effective, producing 432.0 GB/s of bandwidth. The N1X 40SM uses 128 GB of LPDDR5X on a 256-bit bus, with memory at 1067 MHz for 8.5 Gbps effective, producing 273.2 GB/s of bandwidth. The N1X 40SM has far more capacity, but the RX 9070 GRE delivers significantly more bandwidth. Pixel and texture rates reflect these differences. The RX 9070 GRE outputs 267.8 GPixel/s and 535.7 GTexel/s, while the N1X 40SM outputs 93.84 GPixel/s and 750.7 GTexel/s. The RX 9070 GRE wins on pixel throughput by a wide margin, while the N1X 40SM wins on texture throughput.

Compute throughput follows the expected pattern. The RX 9070 GRE reaches 34.28 TFLOPS for both FP32 and FP16, at a 1:1 ratio. The N1X 40SM delivers 24.02 TFLOPS for both FP32 and FP16, also at 1:1. The RX 9070 GRE leads by roughly 10 TFLOPS in each precision class. The power and physical profiles differ just as much. The RX 9070 GRE is a dual-slot card with a 220 W TDP, two 8-pin power connectors, and a suggested PSU of 550 W. The N1X 40SM is an IGP with no listed TDP and no power connectors. The RX 9070 GRE uses PCIe 5.0 x16 and offers one HDMI 2.1b port plus three DisplayPort 2.1a outputs. The N1X 40SM also uses PCIe 5.0 x16 but provides only a single HDMI output. API support diverges completely: the RX 9070 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan.

Where Each One Wins

The data separates these two parts into distinct roles. The RX 9070 GRE wins on raw rendering throughput in every measured category that has numbers. Its FP32 output of 34.28 TFLOPS is 42.7% higher than the N1X 40SM's 24.02 TFLOPS. Its pixel rate of 267.8 GPixel/s is nearly triple the N1X 40SM's 93.84 GPixel/s. Its memory bandwidth of 432.0 GB/s exceeds the N1X 40SM's 273.2 GB/s by a wide margin. Higher clock speeds, from the 1420 MHz base to the 2790 MHz boost, support those output rates. The RX 9070 GRE also brings full API support for modern graphics workloads, while the N1X 40SM has no API entries in its record.

The N1X 40SM wins where capacity and parallel width matter. Its 5120 shading units outnumber the RX 9070 GRE's 3072 by roughly two-thirds. Its 320 TMUs exceed the RX 9070 GRE's 192. Its 128 GB of memory dwarfs the RX 9070 GRE's 12 GB, and its 256-bit bus is wider than the 192-bit bus on the AMD part. The 160 tensor cores give the N1X 40SM a dedicated AI processing path that the RX 9070 GRE does not list. The N1X 40SM also consumes no external power connectors and is classified as an IGP, so it fits into systems without a discrete power delivery path.

The RX 9070 GRE's nearest rival data places it in a competitive cluster. It sits just 0.7% behind the Intel Arc A580, 1.2% behind the AMD Radeon RX 5600 OEM, 1.5% behind the Intel Arc A570M, and 1.8% behind the AMD Radeon RX 6950 XT in average score. These margins are small enough that the RX 9070 GRE trades places with those parts depending on the workload. The N1X 40SM has no such comparisons, so its standing in the database rests on the 50th percentile alone, which indicates a median position among all recorded GPUs.

The Verdict

The recorded data points to different buyers for each part. The AMD Radeon RX 9070 GRE is a discrete graphics card with completed benchmark results, a 87th percentile standing, and a launch MSRP of 549 USD. It delivers 34.28 TFLOPS of FP32 compute, 267.8 GPixel/s of pixel throughput, and 432.0 GB/s of memory bandwidth. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it carries a 220 W TDP with dual-slot cooling. Anyone building a system around a PCIe 5.0 x16 slot with two 8-pin connectors and a 550 W PSU can use the RX 9070 GRE for graphics workloads, and the benchmark data confirms it performs near the level of the Intel Arc A580, the AMD Radeon RX 5600 OEM, the Intel Arc A570M, and the AMD Radeon RX 6950 XT.

The NVIDIA N1X 40SM is an integrated graphics processor with no completed benchmarks, no average score, and no nearest rivals in the database. It has more shading units, more TMUs, more memory, and tensor cores, but its clocks are lower, its pixel rate is far lower, and its memory bandwidth is lower. Its place in the 50th percentile suggests a median performer among all GPUs, but without recorded test scores, the database cannot verify its real-world speed. Systems that need a single HDMI output, no external power connectors, and a 128 GB unified memory pool would align with the N1X 40SM's specifications.

The choice depends on what the data shows. For measured graphics performance, the RX 9070 GRE has the scores. For integrated deployment with massive memory capacity and no power connectors, the N1X 40SM has the specifications. Both parts are listed as Active in production status, and both use PCIe 5.0 x16. The RX 9070 GRE released on 2025-05-07, while the N1X 40SM has a release date of 2026-05-31. The RX 9070 GRE belongs to the Radeon RX 9000 series with a predecessor in Navi III, while the N1X 40SM has no predecessor listed. No successor is listed for either part.
