AMD Radeon RX Vega M GH vs NVIDIA GeForce RTX 3070 Ti Comparison

The NVIDIA GeForce RTX 3070 Ti and AMD Radeon RX Vega M GH occupy vastly different tiers of the GPU market, and the benchmark data reflects this clearly. The RTX 3070 Ti, a discrete desktop card from the Ampere generation, outperforms the Vega M GH, an integrated graphics processor (IGP) from AMD's GCN 4.0 architecture, by a massive margin in all shared tests. The data shows the RTX 3070 Ti is the unequivocal choice for any workload demanding high frame rates or compute throughput, while the Vega M GH’s only advantage lies in its integration and power profile, not performance. This comparison is less about a fair fight and more about illustrating the generational and design gap between a high-end add-in board and a mobile-oriented IGP.

The Verdict

Who should pick which, strictly from the data? The answer is straightforward for anyone building a desktop system with a dedicated graphics card: the NVIDIA GeForce RTX 3070 Ti is the only viable option for serious performance. Its average benchmark score of 29,945 places it in the 75th percentile of all GPUs, while the Vega M GH scores 29,197 on average, sitting at the 74th percentile. The similarity in these percentile rankings is deceptive, as the RTX 3070 Ti dominates in raw compute, with an FP32 rating of 21.75 TFLOPS compared to the Vega M GH's 3.656 TFLOPS.

The RTX 3070 Ti wins both head-to-head benchmark tests outright. In Geekbench OpenCL, it scores 119,718 against 27,125 for the Vega M GH, a delta of 341.4%. In Geekbench Vulkan, the lead is even larger at 346.3%, with scores of 139,541 and 31,268 respectively. The data indicates that the RTX 3070 Ti is not just faster; it is in a different performance class entirely. The Vega M GH, conversely, is an end-of-life IGP with a 100 W TDP, designed for compact or portable systems where a dedicated card is impossible. It should only be considered by users who are constrained to a platform with no PCIe slot for a discrete GPU and require any level of 3D acceleration beyond basic integrated graphics.

Where Each One Wins

Based on the benchmark wins, the RTX 3070 Ti wins in every measurable category. The head-to-head data shows it leading in both OpenCL and Vulkan compute tests. Its 8 GB of GDDR6X memory on a 256-bit bus delivers 608.3 GB/s of bandwidth, which is 3x the 204.8 GB/s available to the Vega M GH's 4 GB of HBM2 on a 1024-bit bus. This memory advantage, combined with 6144 shading units versus 1536, makes the RTX 3070 Ti the clear winner for any GPU-intensive task, including gaming at high resolutions, 3D rendering, and compute workloads like OpenCL.

The Vega M GH's only "win" is in its physical and power characteristics. It is an IGP with no power connectors, a 100 W TDP, and a "Portable Device Dependent" display output, making it suitable for ultra-compact laptops. It has no dedicated rivals in terms of performance, but its nearestRivals list includes the AMD Radeon RX 470, which is only 0.7% ahead in average score. This shows the Vega M GH is roughly comparable to a low-end discrete GPU from several years prior, but it cannot compete with the RTX 3070 Ti, which sits near the performance of an AMD Radeon RX 6800 (which is 0.5% ahead of the 3070 Ti) or a GeForce RTX 2080 Ti (which is 0.5% behind).

Architecture Differences

The two GPUs are separated by generation, process node, and design philosophy. The NVIDIA GeForce RTX 3070 Ti uses the GA104 chip built on Samsung's 8 nm process. It contains 17,400 million transistors on a 392 mm² die, achieving a transistor density of 44.4M / mm². It is based on the Ampere architecture, which includes 48 RT cores and 192 tensor cores, enabling hardware-accelerated ray tracing and AI features like DLSS. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. The card has a 290 W TDP, is dual-slot, and requires a 600 W power supply and a single 12-pin power connector. It was released on May 30, 2021, and is now end-of-life, with a launch MSRP of 599 USD.

In contrast, the AMD Radeon RX Vega M GH is built on the much older Polaris 22 chip using GlobalFoundries' 14 nm process. It packs 5,000 million transistors into a 208 mm² die, for a density of 24.0M / mm². This is a GCN 4.0 architecture part, which lacks dedicated RT or tensor cores. It supports DirectX 12 (12_0), but not the Ultimate feature set, and Vulkan 1.3. The Vega M GH is an IGP with a 100 W TDP, no power connectors, and no specified dimensions, as it is soldered onto a motherboard. It was released on January 31, 2018, and is also end-of-life. The differences in process node (8 nm vs 14 nm) and architecture (Ampere vs GCN 4.0) explain the massive performance gulf, with the newer NVIDIA part having over three times the transistor count and nearly double the die area.

FAQ

Head-to-Head Benchmarks

The head-to-head data is limited to two tests, but the results are decisive. In Geekbench OpenCL, the NVIDIA GeForce RTX 3070 Ti scores 119,718, which is 341.4% higher than the AMD Radeon RX Vega M GH's score of 27,125. This test measures general-purpose compute performance, and the NVIDIA card's 21.75 TFLOPS of FP32 throughput dwarfs the AMD part's 3.656 TFLOPS. The delta of 341.4% means the RTX 3070 Ti is roughly 4.4 times faster, which aligns with the difference in shading units (6144 vs 1536) and texture rate (339.8 GTexel/s vs 114.2 GTexel/s).

The second test, Geekbench Vulkan, shows an even larger lead. The RTX 3070 Ti scores 139,541 against 31,268 for the Vega M GH, a delta of 346.3%. This is slightly higher than the OpenCL gap, indicating the newer Ampere architecture has a more efficient Vulkan driver or better hardware utilization for this API. The RTX 3070 Ti's support for DirectX 12 Ultimate and Vulkan 1.4, versus the Vega M GH's older DirectX 12 (12_0) and Vulkan 1.3, likely contributes to this margin.

The data for the RTX 3070 Ti also includes several other benchmarks not run on the Vega M GH, such as 3DMark Steel Nomad DX12 (score of 3478) and Passmark G3D (score of 23356). These scores confirm its strong standing in the 75th percentile of all GPUs, with nearest rivals including the RTX 5070 Mobile (0.1% ahead) and RTX 2080 Ti (0.5% behind). The Vega M GH, with only its two Geekbench results, is in the 74th percentile, surrounded by much older or lower-end parts like the AMD FirePro W8000 (0% delta) and Intel Arc A370M (0.1% delta). This comparison shows that while the percentile rankings are close, the RTX 3070 Ti is competing with modern high-end hardware, while the Vega M GH is matched against legacy professional and entry-level mobile GPUs.
