AMD Radeon RX 7600S vs NVIDIA N1X 40SM Comparison

AMD Radeon RX 7600S and NVIDIA N1X 40SM represent two fundamentally different approaches to mobile graphics, and the recorded data shows they target distinct usage scenarios. The RX 7600S arrives with a complete benchmark suite and an average score of 16696, while the N1X 40SM has no recorded benchmark scores, an average score of 0, and a percentile rank of 50 compared to the RX 7600S's 60th percentile. The N1X 40SM offers vastly more memory and shading resources, but the RX 7600S holds all measurable performance data in the database.

Where Each One Wins

The RX 7600S wins in every measurable benchmark category, simply because it is the only one of the two with recorded scores. The database lists ten separate test results for the RX 7600S, spanning DirectX variants, OpenCL, Vulkan, and compute workloads. Its strongest results appear in Geekbench Vulkan with a score of 73868, followed by Geekbench OpenCL at 68012. The Passmark G3D score of 15408 and Passmark GPU Compute score of 6520 provide additional evidence of its capability across different rendering APIs and general-purpose compute tasks.

The N1X 40SM wins in no recorded benchmark categories, as its benchmark array is empty. However, its hardware specifications suggest a different type of workload entirely. With 128 GB of LPDDR5X memory on a 256-bit bus delivering 273.2 GB/s of bandwidth, the N1X 40SM is configured for large data sets and memory-intensive operations, not for traditional gaming benchmarks. Its 5120 shading units, 320 texture mapping units, and 160 tensor cores far exceed the RX 7600S's 1792 shading units, 112 TMUs, and 28 ray tracing cores, indicating a design oriented toward compute throughput rather than rasterization speed. The data shows the RX 7600S owns the gaming and conventional graphics benchmark space, while the N1X 40SM appears built for workloads where massive memory capacity and raw shader count matter more than benchmark scores.

Architecture Differences

The architectural split between these two GPUs is stark. The RX 7600S uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, fabricated on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die. It belongs to the Navi Mobile generation within the RX 7000 series. Its transistor density reaches 65.2 million per square millimeter. The N1X 40SM uses the GB20B chip on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC with a die size of 382 mm², though its transistor count is listed as unknown. It belongs to the Blackwell IGP generation under the N1x family designation.

Neither GPU uses external power connectors, and both are classified as IGP slot width, meaning integrated graphics packages. The RX 7600S connects via PCIe 4.0 x16, while the N1X 40SM uses PCIe 5.0 x16, a newer interface generation. The RX 7600S 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, suggesting it may not target conventional graphics APIs at all or that its API support is not yet recorded. The RX 7600S has portable device dependent display outputs, while the N1X 40SM lists a single HDMI output.

Clock behavior also differs. The RX 7600S has a base clock of 1500 MHz, a boost clock of 2200 MHz, and a game clock of 1865 MHz, with memory running at 2000 MHz or 16 Gbps effective. The N1X 40SM has a much lower base clock of 741 MHz but a higher boost clock of 2346 MHz, with memory at 1067 MHz or 8.5 Gbps effective. This suggests the RX 7600S maintains higher sustained clocks while the N1X 40SM relies on aggressive boost behavior.

Head-to-Head Benchmarks

Since the N1X 40SM has no recorded benchmark scores, direct head-to-head comparisons must rely on the RX 7600S's nearest rivals to contextualize its performance. The RX 7600S's average benchmark score of 16696 places it in close competition with the NVIDIA T400 4 GB, which scores 16792, a delta of -0.6 percent, meaning the RX 7600S trails that card by less than one percent. Against the NVIDIA T400, which scores 16508, the RX 7600S leads by 1.1 percent. The NVIDIA GeForce RTX 5090 D V2 scores 16504, giving the RX 7600S a 1.2 percent advantage. The NVIDIA Tesla M4 scores 16932, putting the RX 7600S behind by 1.4 percent.

These narrow deltas indicate the RX 7600S sits in a tight performance cluster where single-digit percentage differences separate it from its nearest competitors. The RX 7600S's individual benchmark results show its strongest relative performance in Vulkan and OpenCL compute tests, with Geekbench Vulkan at 73868 and Geekbench OpenCL at 68012. Its Passmark DirectX 9 score of 211 and Passmark G2D score of 776 show reasonable legacy and 2D performance, while Passmark DirectX 11 at 140 and DirectX 12 at 65 indicate weaker results in those specific API tests. The 3DMark Steel Nomad DX12 score of 1888 provides a modern gaming workload reference point.

The RX 7600S's 60th percentile ranking among all GPUs in the database places it above the N1X 40SM's 50th percentile, though the N1X 40SM's lack of benchmark data makes this comparison mostly nominal. The data shows the RX 7600S delivers consistent, measurable performance across a range of tests, while the N1X 40SM offers no comparable numbers to evaluate.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The RX 7600S uses 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth, while the N1X 40SM uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth, a 16x capacity advantage and a 6.7 percent bandwidth advantage. The RX 7600S has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, with no tensor cores listed. The N1X 40SM has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores.

Pixel and texture rates diverge significantly. The RX 7600S achieves 140.8 GPixel/s pixel rate and 246.4 GTexel/s texture rate. The N1X 40SM achieves 93.84 GPixel/s pixel rate, which is 33 percent lower, but 750.7 GTexel/s texture rate, which is 205 percent higher. Compute throughput shows the RX 7600S at 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 with a 2:1 ratio, while the N1X 40SM reaches 24.02 TFLOPS FP32 and 24.02 TFLOPS FP16 with a 1:1 ratio, indicating the latter does not double FP16 throughput.

The RX 7600S has a power draw of 75 W, while the N1X 40SM lists unknown power draw. Process nodes differ at 6 nm versus 5 nm, both TSMC. The RX 7600S has a release date of January 3, 2023, while the N1X 40SM lists May 31, 2026. The RX 7600S names Polaris Mobile as its predecessor, while the N1X 40SM has no predecessor listed. Both are active production status and neither has a successor.

The Verdict

The data supports a clear division of roles. The AMD Radeon RX 7600S is the only one of the two with measurable benchmark performance, and its results place it in a competitive cluster with NVIDIA T400 series cards and the GeForce RTX 5090 D V2, with deltas ranging from -1.4 percent to 1.2 percent. Its 60th percentile ranking, 75 W power draw, and full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 make it a functional graphics solution for gaming and conventional rendering workloads. Its 8 GB memory and 128-bit bus are modest, but its 256.0 GB/s bandwidth and 15.77 TFLOPS FP32 provide a balanced profile for its class.

The NVIDIA N1X 40SM presents a different proposition entirely. With no benchmarks, no API support listed, and unknown power draw, it cannot be evaluated on traditional graphics performance. Its 128 GB memory, 5120 shading units, 160 tensor cores, and 750.7 GTexel/s texture rate indicate a design for massive parallel compute tasks, likely in AI or data processing contexts where memory capacity and tensor throughput dominate. Its 382 mm² die on 5 nm and PCIe 5.0 interface suggest a modern, high-bandwidth platform, but the absence of recorded data means no performance conclusions can be drawn. The RX 7600S wins the benchmark battle by default, but the N1X 40SM's specifications target a different battlefield where scoreboards may not apply.
