AMD Radeon RX 6700 vs AMD Radeon RX Vega M GH Comparison

The AMD Radeon RX 6700 and AMD Radeon RX Vega M GH represent two distinct approaches to graphics processing, separated by process technology, memory design, and intended use case. The RX 6700 is a discrete, end-of-life desktop part from the Radeon RX 6000 series, built on the RDNA 2.0 architecture with a 7 nm process. The RX Vega M GH is an integrated graphics processor from the Vega generation, using the older GCN 4.0 architecture on a 14 nm process, designed for portable devices. Benchmark data shows the RX 6700 leads decisively in the two shared tests, but the RX Vega M GH occupies a different performance tier. The analysis below walks through the specific wins, architectural disparities, and the practical implications of each card’s data.

Where Each One Wins

The data presents a clear split in capabilities. The AMD Radeon RX 6700 wins every head-to-head benchmark available, with a 100% win rate across the two shared tests. Its average benchmark score of 30433 places it in the 75th percentile of all GPUs, indicating it sits above the majority of graphics hardware. The RX Vega M GH, by contrast, has an average benchmark score of 29197, placing it in the 74th percentile—a close overall standing, yet one achieved through a very different benchmark profile.

The RX 6700’s wins are substantial in compute-oriented workloads. In the Geekbench OpenCL test, it scores 97841 against the Vega M GH’s 27125, a delta of 260.7%. This indicates the RX 6700 is overwhelmingly faster in general-purpose compute tasks that leverage OpenCL. In the Geekbench Vulkan test, the RX 6700 scores 83974 versus 31268, a 168.6% advantage, showing dominance in modern graphics APIs as well.

The RX Vega M GH’s wins are not in raw performance but in efficiency and form factor. As an IGP with a 100 W TDP, it requires no power connectors and is portable-device dependent for display output. The RX 6700, with a 175 W TDP and a dual-slot design requiring a 450 W PSU, cannot match this integration. For users prioritizing a compact, low-power solution, the Vega M GH is the only option between the two, though its benchmark scores lag significantly.

Head-to-Head Benchmarks

The head-to-head data is limited to two tests, but both show a dominant performance from the RX 6700. In Geekbench OpenCL, the RX 6700 scores 97841 against the RX Vega M GH’s 27125. The delta of 260.7% is the largest margin in any comparison between the two. This means the RX 6700 delivers roughly 3.6 times the OpenCL compute performance of the Vega M GH. Such a gap suggests the RX 6700 is vastly better suited for compute-heavy applications like rendering or scientific workloads that rely on OpenCL.

In Geekbench Vulkan, the RX 6700 scores 83974, while the RX Vega M GH achieves 31268. The 168.6% delta translates to the RX 6700 being about 2.7 times faster. Vulkan is a low-overhead graphics API used in modern games and professional applications, so this result indicates the RX 6700 will provide a smoother experience in Vulkan-based titles. The gap is smaller than in OpenCL, but still substantial.

The RX 6700 also shows a broader benchmark coverage, with scores available across 3DMark Steel Nomad DX12, Geekbench Metal, Passmark DirectX 9/10/11/12, Passmark G2D, G3D, and GPU Compute. The RX Vega M GH only has scores for Geekbench OpenCL and Geekbench Vulkan. This lack of data for the Vega M GH in other tests means its overall capability in DirectX or Passmark workloads cannot be directly compared, but the available data consistently favors the RX 6700.

Specification Differences

The two GPUs differ across nearly every core specification. The RX 6700 has 2304 shading units, 144 texture mapping units, and 64 ROPs. The RX Vega M GH has 1536 shading units, 96 TMUs, and 64 ROPs. The RX 6700 also features 36 ray tracing cores, while the Vega M GH has none. Clock speeds are significantly higher on the RX 6700, with a base of 1941 MHz and a boost of 2450 MHz, compared to the Vega M GH’s 1063 MHz base and 1190 MHz boost.

Memory configurations are also divergent. The RX 6700 uses 10 GB of GDDR6 memory on a 160-bit bus, yielding 320.0 GB/s of bandwidth. The RX Vega M GH uses 4 GB of HBM2 on a 1024-bit bus, producing 204.8 GB/s. Despite the wider bus, the Vega M GH’s lower memory clock of 800 MHz results in less bandwidth. Pixel rate on the RX 6700 is 156.8 GPixel/s, double the Vega M GH’s 76.16 GPixel/s. Texture rate is 352.8 GTexel/s versus 114.2 GTexel/s, and FP32 performance is 11.29 TFLOPS compared to 3.656 TFLOPS.

The RX 6700 is a dual-slot card with a 1x 8-pin power connector and a suggested PSU of 450 W. The RX Vega M GH is an IGP with no power connectors and no suggested PSU. The RX 6700 has a 267 mm length, 110 mm height, and 40 mm width, while the Vega M GH has no listed dimensions. The RX 6700 supports PCIe 4.0 x16, while the Vega M GH uses an IGP bus interface.

Architecture Differences

The architectural gap is generational. The RX 6700 uses RDNA 2.0, AMD’s second-generation Radeon DNA architecture, which introduces hardware ray tracing and a redesigned compute unit layout. It is built on a 7 nm process at TSMC, with 17,200 million transistors on a 335 mm² die, yielding a transistor density of 51.3M / mm². The RX Vega M GH uses GCN 4.0, the Graphics Core Next architecture from 2018, which lacks dedicated ray tracing hardware. It is built on a 14 nm process at GlobalFoundries, with 5,000 million transistors on a 208 mm² die, for a density of 24.0M / mm².

The FP16 performance differs markedly. The RX 6700 achieves 22.58 TFLOPS FP16 with a 2:1 ratio, meaning it can double its FP32 throughput for half-precision workloads. The RX Vega M GH achieves 3.656 TFLOPS FP16 with a 1:1 ratio, meaning it has no FP16 acceleration advantage. This makes the RX 6700 more capable in emerging workloads that leverage FP16, such as certain AI inference tasks.

API support also differs. The RX 6700 supports DirectX 12 Ultimate (12_2), which includes features like variable rate shading and mesh shaders. The RX Vega M GH supports DirectX 12 (12_0), lacking those advanced features. Vulkan support is version 1.4 on the RX 6700 versus 1.3 on the Vega M GH. Both support OpenGL 4.6. The RX 6700’s display outputs include 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Vega M GH is portable-device dependent, meaning its outputs vary by the host system.

The Verdict

The data points to a clear choice for most users. The AMD Radeon RX 6700 is the superior performer in every shared benchmark, with a 260.7% lead in OpenCL and a 168.6% lead in Vulkan. Its higher average benchmark score of 30433 versus 29197, combined with a larger feature set including ray tracing and DirectX 12 Ultimate, makes it the appropriate pick for any desktop build where performance is the priority. Its 10 GB of memory and 320.0 GB/s bandwidth also provide more headroom for modern game textures and compute tasks.

The AMD Radeon RX Vega M GH, however, is not without a role. Its 100 W TDP and IGP form factor mean it can be integrated into portable devices without discrete power connectors, something the RX 6700 cannot offer with its 175 W TDP and dual-slot design. For a user building or buying a compact system where power draw and physical space are the primary constraints, the Vega M GH is the only feasible option between the two. Its 4 GB of HBM2 memory on a 1024-bit bus still provides respectable bandwidth for its class, and its 74th percentile ranking shows it is not a slouch relative to all GPUs.

The verdict is straightforward: the RX 6700 wins on absolute performance, architectural modernity, and feature support. The RX Vega M GH wins on integration and power efficiency. The choice depends entirely on whether the system is a desktop with room for a discrete card or a mobile/compact platform requiring an IGP. For any workload where benchmark scores matter, the RX 6700 is the definitive answer.
