AMD Radeon RX 7900M vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The benchmark database contains three recorded test results for the AMD Radeon RX 7900M, while the NVIDIA N1X 40SM has no recorded benchmark scores. This asymmetry makes direct head-to-head comparisons impossible, but the available data for the AMD part can still be positioned against the broader GPU landscape.

The AMD Radeon RX 7900M posts a 3DMark Steel Nomad DX12 score of 4201. In Geekbench OpenCL, it records 129499 points, and in Geekbench Vulkan, it reaches 158760 points. These three results produce an average benchmark score of 97487 for the AMD part, placing it in the 94th percentile of all GPUs in the database.

The NVIDIA N1X 40SM, by contrast, holds a 50th percentile ranking with an average benchmark score of 0, reflecting the absence of any recorded test results. The database shows no head-to-head benchmark entries between these two products, and neither side registers a win in direct comparison.

When examining the AMD Radeon RX 7900M against its nearest rivals, the data reveals a tight cluster of performance. The AMD Radeon Pro VII averages 97131, which is 0.4% below the RX 7900M. The NVIDIA Quadro RTX 6000 averages 101872, putting it 4.3% ahead of the RX 7900M. The AMD Radeon Instinct MI60 averages 92466, trailing the RX 7900M by 5.4%. The NVIDIA RTX A4500 averages 91671, sitting 6.3% behind the RX 7900M.

These results indicate that the RX 7900M holds a narrow edge over several professional workstation GPUs, but it does not lead the field. The Quadro RTX 6000 stands as the strongest competitor among the recorded rivals, outpacing the RX 7900M by roughly 4 percentage points in average score. The margin between the RX 7900M and the Radeon Pro VII is essentially negligible at less than half a percentage point, meaning the two effectively trade blows in aggregate performance.

For the NVIDIA N1X 40SM, the absence of benchmark data means no performance claims can be derived from the database. Its 50th percentile placement is a neutral default rather than a measured outcome, and the lack of nearest rivals further underscores the absence of comparative evidence.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 7900M is the only one of the two products with measurable performance. Its 94th percentile ranking and average score of 97487 place it among the stronger GPUs in the database, though not at the very top. The NVIDIA Quadro RTX 6000 demonstrates that other parts can still exceed it by a few percentage points.

The NVIDIA N1X 40SM offers no benchmark evidence to support any performance conclusion. With an average score of 0 and no rivals listed, the database provides no basis for recommending it over the RX 7900M or any other GPU. Its 50th percentile ranking carries no analytical weight without underlying test results.

For a user choosing between these two specific products, the data points decisively toward the AMD Radeon RX 7900M. It has verified scores across three distinct benchmark suites, a high percentile placement, and a set of comparable rivals that bracket its performance. The N1X 40SM, by contrast, exists in the database without any recorded measurements, making any performance-based selection in its favor unsupported by the available information.

The RX 7900M also shows clear strengths in specific workload categories. Its Geekbench Vulkan score of 158760 exceeds its OpenCL score of 129499 by roughly 23%, suggesting particular efficiency in Vulkan-based compute or graphics tasks. The 3DMark Steel Nomad DX12 result of 4201 provides a separate data point for DirectX 12 workloads, and while no direct rival comparison exists for that specific test, the score contributes to the overall average that places the card in the 94th percentile.

Specification Differences

Architecture Differences

The AMD Radeon RX 7900M belongs to the Radeon RX 7000 series and uses the Navi 31 chip with RDNA 3.0 architecture. Its codename is Plum Bonito, and it comes from the Navi Mobile generation within the RX 7000M family. The predecessor is listed as Polaris Mobile, and there is no successor recorded.

The NVIDIA N1X 40SM uses the GB20B chip with Blackwell 2.0 architecture. It belongs to the Blackwell IGP generation under the N1x naming scheme. No codename, predecessor, or successor is recorded for this part.

The architectural differences extend to the compute and memory designs. The RX 7900M uses GDDR6 memory with a 256-bit bus and a high 576.0 GB/s bandwidth, consistent with a discrete-class mobile GPU design. The N1X 40SM uses LPDDR5X with the same 256-bit bus but only 273.2 GB/s bandwidth, suggesting a different memory strategy focused on capacity rather than throughput.

The RX 7900M includes dedicated ray tracing hardware with 72 cores, and its FP16 throughput is double its FP32 throughput, indicating a 2:1 ratio typical of consumer gaming architectures. The N1X 40SM includes 160 tensor cores, which the RX 7900M lacks entirely, and its FP16 throughput matches its FP32 throughput at a 1:1 ratio. This suggests the N1X 40SM is designed with a different compute philosophy, potentially prioritizing tensor operations for certain workloads over conventional FP16 acceleration.

The RX 7900M supports a full modern API stack including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists no API support in the database, which may reflect its unverified status or a different software interface model. The RX 7900M also carries a higher transistor density at 109.1M per mm², while the N1X 40SM has no density figure recorded.

The ROP count difference is particularly stark: 192 ROPs on the RX 7900M versus 40 ROPs on the N1X 40SM. This explains the pixel rate gap of 401.3 GPixel/s versus 93.84 GPixel/s. The RX 7900M is built for high fill-rate rendering, while the N1X 40SM appears oriented toward compute throughput with its higher TMU count and tensor core array.

The power delivery approach also differs. The RX 7900M has a recorded 180 W TDP, while the N1X 40SM has no TDP listed. Both are IGP slot width with no power connectors. The RX 7900M uses PCIe 4.0 x16, while the N1X 40SM uses PCIe 5.0 x16, giving the NVIDIA part a newer bus interface.

The release timeline places the RX 7900M in late 2023 and the N1X 40SM in mid-2026, suggesting the NVIDIA part is a newer design despite its lack of benchmark data. The architectural differences reflect two distinct design goals: the RX 7900M emphasizes rasterization performance, memory bandwidth, and FP32/FP16 compute, while the N1X 40SM emphasizes memory capacity, tensor cores, and texture throughput.
