AMD Radeon RX 7800M vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the AMD Radeon RX 7800M, which takes 7 of the 10 recorded head-to-head tests. The most striking margin comes in the Geekbench Vulkan test, where the AMD part scores 126,668 against the NVIDIA GeForce RTX 3070 Ti Mobile's 100,027, a 26.6% advantage. This is the largest single-test gap in the entire comparison and suggests a substantial lead in modern graphics API workloads.

The 3DMark Steel Nomad DX12 test, which represents a current-generation gaming workload, also favors the RX 7800M by a healthy margin: 2,994 versus 2,572, a 16.4% difference. This result aligns with the broader pattern of the AMD card leading in newer API scenarios. The PassMark DirectX 12 test reinforces this, with the RX 7800M scoring 89 against the RTX 3070 Ti Mobile's 73, a 21.9% advantage.

Compute workloads show a similar story. In the PassMark GPU Compute test, the RX 7800M posts 9,342 points versus 7,504 for the NVIDIA card, a 24.5% gap. The Geekbench OpenCL test follows the same trend: 120,778 for AMD against 106,022 for NVIDIA, a 13.9% lead. These results indicate that the Radeon part holds a consistent edge in raw compute throughput across multiple benchmarking suites.

The DirectX 11 test also goes to AMD, with 176 points against 153, a 15% lead. The PassMark G2D test, which measures 2D graphics performance, shows the RX 7800M ahead by 13.9%, scoring 892 versus 783.

The NVIDIA card does claim victories, but they are narrower and concentrated in older or less demanding workloads. The PassMark DirectX 10 test goes to the RTX 3070 Ti Mobile by 20.2%, scoring 124 against 99. The DirectX 9 test also favors NVIDIA, 196 versus 174, an 11.2% margin. The PassMark G3D test, which aggregates overall 3D performance, is essentially a tie: NVIDIA edges ahead by just 0.6%, scoring 17,727 against 17,613.

The overall average benchmark score reflects this split. The RX 7800M averages 27,883 points across its recorded tests, while the RTX 3070 Ti Mobile averages 23,518, a difference of roughly 18.6%. The AMD card also sits at the 73rd percentile of all GPUs in the database, compared to the 69th percentile for NVIDIA. Interestingly, the RX 7800M's closest rivals by average score are the AMD Radeon Pro Vega 20 (0.2% behind), the AMD Radeon Pro W5500X (0.3% ahead), and the NVIDIA GeForce GTX 980 Ti (0.5% ahead).

Architecture Differences

The two GPUs come from different architectural generations and foundries. The AMD Radeon RX 7800M is built on RDNA 3.0 architecture, uses the Navi 32 chip, and is manufactured on a 5 nm process at TSMC. The NVIDIA GeForce RTX 3070 Ti Mobile uses the Ampere architecture with the GA104 chip, fabricated on an 8 nm process at Samsung. The process node difference is significant: the AMD chip packs 28,100 million transistors into a 346 mm² die, yielding a transistor density of 81.2 million transistors per mm². The NVIDIA chip contains 17,400 million transistors on a larger 392 mm² die, giving a density of just 44.4 million per mm². The RX 7800M therefore achieves roughly 83% higher transistor density despite the smaller die.

The compute layout differs substantially. The RX 7800M has 3,840 shading units, 240 texture mapping units, and 96 render output units. The RTX 3070 Ti Mobile has 5,888 shading units, 184 TMUs, and 96 ROPs. Although NVIDIA's card has more than 50% more shading units, the AMD card achieves higher throughput: 35.87 TFLOPS FP32 versus 16.60 TFLOPS for NVIDIA. The same pattern appears in texture and pixel rates: the RX 7800M reaches 560.4 GTexel/s and 224.2 GPixel/s, while the RTX 3070 Ti Mobile manages 259.4 GTexel/s and 135.4 GPixel/s.

Ray tracing hardware differs in configuration. The RX 7800M has 60 ray tracing cores, while the RTX 3070 Ti Mobile has 46. The NVIDIA card additionally includes 184 tensor cores, which the AMD card does not list. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity is complete.

The production status also differs: the RX 7800M is listed as Active, while the RTX 3070 Ti Mobile is End-of-life. The AMD card was released on September 10, 2024, whereas the NVIDIA card launched on January 3, 2022, making it roughly two and a half years older.

Specification Differences

Memory configuration is a key differentiator. The RX 7800M offers 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The RTX 3070 Ti Mobile offers 8 GB of GDDR6 on a wider 256-bit bus, achieving 448.0 GB/s. The NVIDIA card has a slight bandwidth advantage of 3.7%, but the AMD card has 50% more memory capacity, which can matter in high-resolution or texture-heavy scenarios.

Clock speeds favor AMD significantly. The RX 7800M has a base clock of 1295 MHz and a boost clock of 2335 MHz, with a game clock of 2145 MHz. The RTX 3070 Ti Mobile runs at 915 MHz base and 1410 MHz boost. The memory clock also differs: AMD's runs at 2250 MHz (18 Gbps effective), while NVIDIA's runs at 1750 MHz (14 Gbps effective).

Power draw is another clear distinction. The RX 7800M has a TDP of 180 W, while the RTX 3070 Ti Mobile has a TDP of 115 W. The AMD card consumes 56.5% more power, which is a meaningful consideration for laptop thermal design and battery life. Both cards use PCIe 4.0 x16 interfaces and have no external power connectors listed, with display outputs described as "Portable Device Dependent."

The remaining specifications are identical or not applicable: both have 96 ROPs, both support the same API set, neither has listed dimensions or a suggested PSU, and neither has a launch MSRP recorded in the database.

The Verdict

The data points to the AMD Radeon RX 7800M as the stronger performer in the majority of workloads. It wins the modern API tests, the compute tests, and the overall average score comparison. Its 26.6% lead in Vulkan and 16.4% lead in 3DMark Steel Nomad suggest that it is better suited to current and future game engines. The 24.5% advantage in GPU compute and 13.9% lead in OpenCL make it the better choice for general-purpose compute tasks.

The NVIDIA GeForce RTX 3070 Ti Mobile, however, retains relevance in specific legacy scenarios. Its 20.2% win in DirectX 10 and 11.2% win in DirectX 9 indicate that older titles or applications built on those APIs may run better on the NVIDIA hardware. The near-tie in PassMark G3D (0.6% margin) also shows that in aggregated 3D performance, the two cards are effectively equivalent.

For buyers prioritizing future-proofing, modern API support, and compute throughput, the RX 7800M is the clear pick from the recorded data. For those whose workloads are anchored in older DirectX versions, the RTX 3070 Ti Mobile has a measurable edge. The 50% larger memory capacity of the AMD card (12 GB versus 8 GB) further strengthens its case for texture-heavy or large-dataset workloads, even though the NVIDIA card has slightly higher raw bandwidth.

Where Each One Wins

The AMD Radeon RX 7800M wins in seven categories: 3DMark Steel Nomad DX12, Geekbench OpenCL, Geekbench Vulkan, PassMark DirectX 11, PassMark DirectX 12, PassMark G2D, and PassMark GPU Compute. These wins span current-generation gaming, general compute, and 2D graphics, making it the more versatile card overall. The Vulkan result is particularly strong, and the compute results suggest the card handles non-graphics workloads with ease.

The NVIDIA GeForce RTX 3070 Ti Mobile wins in three categories: PassMark DirectX 10, PassMark DirectX 9, and PassMark G3D. The DirectX 10 and 9 wins are substantial, but they apply to aging API levels. The G3D win is marginal at 0.6%, so it does not represent a meaningful overall 3D advantage. The RTX 3070 Ti Mobile also carries a lower TDP of 115 W versus 180 W, which may make it more attractive for thinner laptops or longer battery life, though this comes with lower peak performance.

In summary, the RX 7800M is the default recommendation for anyone running modern games, Vulkan titles, or compute-heavy applications. The RTX 3070 Ti Mobile remains a reasonable option for legacy DirectX 9/10 software or for users who prioritize lower power consumption over peak performance. The recorded data does not show any scenario where the NVIDIA card wins on both performance and efficiency simultaneously.
