AMD Radeon RX 7900M vs NVIDIA GeForce RTX 4070 AD103 Comparison

The AMD Radeon RX 7900M and NVIDIA GeForce RTX 4070 AD103 represent two distinct approaches to high-performance mobile graphics, built on different architectures and targeting different segments of the laptop market. The RX 7900M uses the Navi 31 chip with RDNA 3.0 architecture, while the RTX 4070 AD103 uses the AD103 chip with Ada Lovelace architecture. The recorded data shows that the RX 7900M holds a significant performance advantage in the benchmarks available, with a percentile rank of 94 against all GPUs compared to the RTX 4070 AD103's percentile rank of 50. However, the RTX 4070 AD103 has an average benchmark score of 0 in the database, meaning no comparable performance data exists for it, while the RX 7900M has an average benchmark score of 97487. This creates an unusual comparison where one part has extensive performance data and the other does not, requiring careful analysis of the architectural and specification differences to understand the expected performance gap.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon RX 7900M and the NVIDIA GeForce RTX 4070 AD103. There are no shared test scores, no comparison fields, and no win counts for either product. The RX 7900M has three recorded benchmark scores: 4201 in 3DMark Steel Nomad DX12, 129499 in Geekbench OpenCL, and 158760 in Geekbench Vulkan. The RTX 4070 AD103 has an empty benchmarks array, meaning no individual test scores are recorded for this specific variant.

The absence of head-to-head data means the performance relationship must be inferred from the overall average scores and the architectural specifications. The RX 7900M's average benchmark score of 97487 places it in the 94th percentile of all GPUs. Its nearest rivals in the database include the NVIDIA Quadro RTX 6000 with an average score of 101872, which is 4.3 percent higher, the AMD Radeon Instinct MI60 with an average score of 92466, which is 5.4 percent lower, and the NVIDIA RTX A4500 with an average score of 91671, which is 6.3 percent lower. The AMD Radeon Pro VII is nearly identical with an average score of 97131, only 0.4 percent lower than the RX 7900M. These comparisons show the RX 7900M sits in a competitive range among professional and workstation-class GPUs.

The RTX 4070 AD103 has an average benchmark score of 0 and no nearest rivals listed, which indicates the database has no performance measurements for this product. The percentile rank of 50 is the midpoint of the distribution, but without actual score data, this rank carries no practical meaning for performance comparison. The GPU's compute capabilities are substantial on paper, with 29.15 TFLOPS of FP32 performance and 29.15 TFLOPS of FP16 performance, but the lack of recorded benchmarks prevents any direct quantitative comparison with the RX 7900M's 38.52 TFLOPS of FP32 and 77.05 TFLOPS of FP16.

The RX 7900M's FP32 throughput is 32 percent higher than the RTX 4070 AD103's FP32 throughput based on the recorded specification data. In FP16 workloads, the RX 7900M's 77.05 TFLOPS is 2.6 times higher than the RTX 4070 AD103's 29.15 TFLOPS, reflecting the AMD part's 2:1 FP16 ratio versus NVIDIA's 1:1 ratio. Pixel throughput also favors the RX 7900M, with 401.3 GPixel/s compared to 158.4 GPixel/s for the RTX 4070 AD103, a difference of 2.5 times. Texture throughput shows a smaller gap, with the RX 7900M delivering 601.9 GTexel/s versus 455.4 GTexel/s for the NVIDIA part, a 32 percent advantage.
