AMD Radeon RX 9070 GRE vs NVIDIA N1 20SM Comparison

The Verdict

The data positions the AMD Radeon RX 9070 GRE as the clear performance leader between these two, with an average benchmark score of 57,367 and an 87th percentile ranking across all GPUs in the database. The NVIDIA N1 20SM, by contrast, sits at the 50th percentile with no recorded average score, placing it in a fundamentally different performance tier. The RX 9070 GRE is for users who need discrete graphics horsepower; the N1 20SM is an integrated graphics part with a massive 128 GB memory pool, suited to specific workloads that demand capacity over throughput.

The RX 9070 GRE delivers 34.28 TFLOPS FP32 compute against 12.01 TFLOPS for the N1 20SM, a 2.85x advantage in raw shader output. The RX 9070 GRE also leads in pixel throughput at 267.8 GPixel/s versus 56.30 GPixel/s, and texture rate at 535.7 GTexel/s versus 375.4 GTexel/s. The only category where the N1 20SM offers a clear edge is memory size: 128 GB of LPDDR5X versus 12 GB of GDDR6. For gaming and standard rendering, the RX 9070 GRE is the only viable choice, while the N1 20SM serves niche, memory-bound compute scenarios.

Architecture Differences

The RX 9070 GRE 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 packs 53,900 million transistors, yielding a density of 151.0M per mm². The N1 20SM uses the GB20B chip on Blackwell 2.0 architecture, fabricated on a 5 nm process, with a larger die at 382 mm² but an unknown transistor count. The RX 9070 GRE belongs to the Navi IV generation within the Radeon RX 9000 series, while the N1 20SM is classified as a Blackwell IGP in the N1x generation.

Core configs differ sharply. The RX 9070 GRE has 3,072 shading units, 192 texture mapping units, 96 ROPs, and 48 ray tracing cores, with no tensor core count listed. The N1 20SM has 2,560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The RX 9070 GRE thus has 20% more shading units, 20% more TMUs, and 4x the ROP count. The N1 20SM brings dedicated tensor cores, a feature absent from the RX 9070 GRE's listed specifications.

Clock behavior differs substantially. The RX 9070 GRE runs a base clock of 1420 MHz, a boost of 2790 MHz, and a game clock of 2220 MHz. The N1 20SM has a much lower base of 741 MHz and a boost of 2346 MHz. Memory architecture also diverges: the RX 9070 GRE uses 12 GB GDDR6 on a 192-bit bus at 2250 MHz (18 Gbps effective), delivering 432.0 GB/s bandwidth. The N1 20SM uses 128 GB LPDDR5X on a 256-bit bus at 1067 MHz (8.5 Gbps effective), delivering 273.2 GB/s bandwidth. The RX 9070 GRE has 58% more memory bandwidth despite the smaller bus width and capacity.

The RX 9070 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM reports N/A for all three APIs, indicating it is not positioned for standard graphics API workloads. The RX 9070 GRE is a dual-slot discrete card with 2x 8-pin power connectors and a 220 W TDP, while the N1 20SM is an IGP with no power connectors and an unknown TDP.

Head-to-Head Benchmarks

Direct benchmark comparisons in the database are unavailable, as the head-to-head benchmark list is empty and the N1 20SM has no recorded benchmark scores. However, the recorded data for the RX 9070 GRE alone provides reference points. In 3DMark Steel Nomad DX12, the RX 9070 GRE scores 5,424. In Geekbench OpenCL, it scores 109,309. The N1 20SM has zero recorded scores in either test, so no direct numerical comparison can be made from the database.

The nearest rivals for the RX 9070 GRE illustrate its standing. The Intel Arc A580 averages 57,756, a 0.7% delta above the RX 9070 GRE. The AMD Radeon RX 5600 OEM averages 58,085, 1.2% higher. The Intel Arc A570M averages 58,239, 1.5% higher. The AMD Radeon RX 6950 XT averages 58,392, 1.8% higher. These deltas show the RX 9070 GRE sits just below a cluster of comparable GPUs, within a tight 1.8% band. The N1 20SM has no nearest rivals listed, reflecting its unique positioning with no comparable entries in the database.

The performance gap between the two target parts is substantial based on compute metrics. The RX 9070 GRE delivers 34.28 TFLOPS FP32, while the N1 20SM delivers 12.01 TFLOPS. The RX 9070 GRE also leads in FP16 at 34.28 TFLOPS versus 12.01 TFLOPS, both at 1:1 ratios. Pixel rate favors the RX 9070 GRE at 267.8 GPixel/s versus 56.30 GPixel/s, a 4.8x advantage. Texture rate favors the RX 9070 GRE at 535.7 GTexel/s versus 375.4 GTexel/s, a 1.4x advantage.

Where Each One Wins

The RX 9070 GRE wins decisively in compute throughput. Its 34.28 TFLOPS FP32 and FP16 output dwarfs the N1 20SM's 12.01 TFLOPS in both formats. It also wins in pixel fill rate at 267.8 GPixel/s versus 56.30 GPixel/s, and texture fill rate at 535.7 GTexel/s versus 375.4 GTexel/s. The RX 9070 GRE has a 432.0 GB/s memory bandwidth advantage over the N1 20SM's 273.2 GB/s, which matters for high-resolution rendering and texture-heavy workloads. It supports the full DirectX 12 Ultimate feature set, making it suitable for modern gaming and graphics applications. Its 8th percentile ranking among all GPUs (87th) confirms broad performance competence.

The N1 20SM wins exclusively on memory capacity. Its 128 GB LPDDR5X pool is more than 10x the RX 9070 GRE's 12 GB, which suits workloads that load very large datasets into memory. It also has 80 tensor cores, a feature the RX 9070 GRE does not list, potentially benefiting AI inference tasks that use tensor operations. The N1 20SM's IGP form factor with no power connectors means it can be integrated into systems without discrete power wiring, though its TDP is unknown. Its 50th percentile ranking places it at the median of all GPUs, but with no average score recorded, its practical performance level remains unquantified in the database.

For gaming, rendering, and standard graphics workloads, the RX 9070 GRE is the clear pick from the data. For memory-capacity-bound compute tasks that require 128 GB of unified memory, the N1 20SM is the only option, but its 12.01 TFLOPS compute ceiling limits its usefulness for compute-heavy operations.
