AMD Radeon RX Vega M GH vs NVIDIA GeForce RTX 5070 Mobile Comparison

# Head-to-Head Benchmarks

The benchmark data between these two mobile GPUs is decisively one-sided. In the two shared tests — Geekbench OpenCL and Geekbench Vulkan — the NVIDIA GeForce RTX 5070 Mobile wins both, and by margins that are difficult to overstate. The OpenCL result shows the RTX 5070 Mobile scoring 122,238 against the RX Vega M GH's 27,125, a 350.6% advantage. That is not a marginal generational gain; it is a category-level difference in compute throughput. The Vulkan result tells the same story, with the RTX 5070 Mobile posting 116,960 versus 31,268 for the Vega part, a 274.1% lead.

Looking at the broader average benchmark score, the RTX 5070 Mobile lands at 29,928, which puts it within 0.1% of the RTX 3070 Ti (29,945) and 0.5% ahead of the RTX 2080 Ti (29,783). The Vega M GH's average of 29,197 places it just 0.1% behind the AMD FirePro W8000 (29,211) and essentially level with the Intel Arc A370M (29,175). The delta between the two GPUs in average score is only about 2.5%, but that small gap masks the massive divergence in modern API workloads — the RTX 5070 Mobile's lead in Vulkan (274.1%) and OpenCL (350.6%) is where the real performance separation lives.

The RTX 5070 Mobile also shows strong legacy DirectX results in its own benchmark suite: Passmark DX11 scores 192, DX9 scores 214, and DX10 scores 129, with a Passmark G3D score of 20,355 and a GPU compute score of 8,279. The Vega M GH has no comparable DirectX or Passmark entries in the data, so cross-comparison there is not possible — but the two Geekbench tests are sufficient to establish the hierarchy.

# Architecture Differences

The architectural gulf between these two parts is enormous, reflecting nearly seven years of GPU development. The RTX 5070 Mobile uses the GB206 chip built on Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It packs 21,900 million transistors into a 181 mm² die, yielding a transistor density of 121.0 million per mm². The Vega M GH, by contrast, uses the Polaris 22 chip with GCN 4.0 architecture, built on a 14 nm process at GlobalFoundries. It contains 5,000 million transistors spread across a larger 208 mm² die, giving a density of just 24.0 million per mm². That density difference — 121.0 vs 24.0 million per mm² — is the single clearest indicator of how much more modern the NVIDIA part is.

The feature sets diverge even more sharply. The RTX 5070 Mobile includes 36 ray tracing cores and 144 tensor cores, both of which are absent entirely from the Vega M GH (the data lists null for both). The NVIDIA part also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Vega M GH tops out at DirectX 12 (12_0) and Vulkan 1.3. Memory technology is another major split: the RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s of bandwidth, while the Vega M GH uses 4 GB of HBM2 on a massive 1024-bit bus but delivers only 204.8 GB/s. That HBM2 setup gives the Vega part a much wider bus but less than half the bandwidth.

Clock behavior is also telling. The Vega M GH runs a higher base clock (1063 MHz vs 907 MHz) and a lower boost clock (1190 MHz vs 1425 MHz) relative to the RTX 5070 Mobile. The NVIDIA part's 1425 MHz boost is substantially higher, and combined with the architectural efficiency of Blackwell 2.0, it produces 13.13 TFLOPS of FP32 performance versus the Vega's 3.656 TFLOPS. That is a 3.6x raw compute advantage for the RTX 5070 Mobile, consistent with the OpenCL delta.

# Where Each One Wins

The RTX 5070 Mobile wins every benchmark category where both parts have data. In OpenCL, its 350.6% lead indicates vastly superior general-purpose compute throughput, which matters for GPU-accelerated productivity tasks, rendering, and machine learning workloads. In Vulkan, the 274.1% lead shows that modern game engines and low-overhead APIs run dramatically better on the NVIDIA part. The RTX 5070 Mobile also brings ray tracing hardware and tensor cores, which the Vega M GH entirely lacks — so any workload involving ray-traced lighting or DLSS-class AI upscaling is simply unavailable on the AMD part.

The Vega M GH's only potential advantages are indirect. Its 100 W TDP is double the RTX 5070 Mobile's 50 W, which suggests the NVIDIA part achieves its massive performance lead at half the power draw. That is not a win for the Vega, but it does indicate the RTX 5070 Mobile is operating in a completely different efficiency class. The Vega part's 64 ROPs versus the RTX 5070 Mobile's 48 ROPs gives it a higher pixel rate (76.16 GPixel/s vs 68.40 GPixel/s), which could theoretically benefit fill-rate-bound scenarios at low resolutions — but with no benchmark data to confirm this, and given the overall compute gap, this is a theoretical edge at best.

The RTX 5070 Mobile also wins on longevity. It is an Active production part released in April 2025, while the Vega M GH is End-of-life and was released in January 2018. For anyone buying into a platform today, the NVIDIA part is the only one with a forward-looking driver and feature roadmap.

# The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 5070 Mobile outperforms the AMD Radeon RX Vega M GH in every shared benchmark, with leads of 350.6% in OpenCL and 274.1% in Vulkan. It does so while consuming half the power (50 W vs 100 W), using a modern 5 nm process versus 14 nm, and supporting newer APIs (DirectX 12 Ultimate and Vulkan 1.4 vs DirectX 12 and Vulkan 1.3). The RTX 5070 Mobile also has ray tracing and tensor cores, which the Vega M GH lacks entirely.

The average benchmark scores are close — 29,928 vs 29,197 — but that metric is misleading. The RTX 5070 Mobile sits in the 75th percentile of all GPUs, while the Vega M GH is at the 74th percentile. When modern workloads are measured, the NVIDIA part is in a different league. The Vega M GH does have a higher pixel rate (76.16 vs 68.40 GPixel/s) and more ROPs (64 vs 48), but no benchmark data supports a real-world win there.

Anyone choosing between these two should pick the RTX 5070 Mobile without hesitation. It is newer, faster, more efficient, feature-rich, and still in active production. The Vega M GH is an end-of-life part from 2018 that cannot compete in any meaningful modern workload. The only scenario where the Vega M GH makes sense is if you are specifically tied to an older platform that requires its IGP bus interface — but even then, the performance gap is so large that upgrading the platform is the better path.
