AMD Radeon RX 570 vs AMD Radeon RX Vega M GH Comparison

AMD Radeon RX Vega M GH and AMD Radeon RX 570 are both GCN 4.0 parts from AMD, but they target completely different use cases: one is an integrated graphics processor (IGP) for portable devices, the other a dual-slot, PCIe add-in board. Benchmark results are unambiguous here. The RX 570 wins both head-to-head tests decisively, leading by 15.5% in Geekbench OpenCL and 26.9% in Geekbench Vulkan. The data shows a clear performance hierarchy, but the Vega M GH’s existence is justified by its form factor and power envelope rather than raw throughput.

Head-to-Head Benchmarks

The only two shared benchmark results are Geekbench OpenCL and Geekbench Vulkan, and the RX 570 dominates both. In Geekbench OpenCL, the RX 570 scores 32,084 against the Vega M GH’s 27,125, a delta of -15.5% for the Vega part. That is a substantial gap, roughly equivalent to the difference between the RX 570 and its nearest rival, the AMD Radeon RX 6800M, which sits only 0.4% below it. The Vulkan test is even more lopsided: the RX 570 posts 42,752 versus 31,268 for the Vega M GH, a 26.9% deficit. In Vulkan, the RX 570 is not just ahead; it is in a different performance class, with a lead larger than the gap between the Vega M GH and its own nearest rival, the AMD FirePro W8000 (which trails by a negligible 0.1%).

Context matters when interpreting these numbers. The Vega M GH’s average benchmark score across all tests is 29,197, while the RX 570’s is 28,766. That means the RX 570’s Vulkan score is an outlier on the high side, whereas the Vega M GH is more consistent. However, in the tests that matter for gaming and compute workloads, the RX 570’s advantage is consistent and large. The Vega M GH does not win a single head-to-head benchmark in this comparison; the RX 570 takes both, giving it a 2-0 record. There is no scenario in these results where the integrated part closes the gap, even at lower resolutions or with API overhead.

Where Each One Wins

The RX 570 wins on raw compute performance in both OpenCL and Vulkan workloads. Its higher shading unit count (2,048 vs 1,536) and texture units (128 vs 96) give it a structural advantage that shows up in every synthetic test. The FP32 throughput of 5.095 TFLOPS versus 3.656 TFLOPS is a 39.4% advantage in raw math, and the texture rate of 159.2 GTexel/s versus 114.2 GTexel/s reinforces that lead. For any workload that stresses shader cores or texture fetch — gaming, rendering, GPU compute — the RX 570 is the clear pick.

The Vega M GH wins on integration and efficiency, though not on any benchmark score. It is an IGP with a 100 W TDP, versus the RX 570’s 150 W TDP. It requires no power connectors, no PCIe slot, and no dual-slot cooler; it is designed to be soldered onto a motherboard. Its memory setup is also fundamentally different: 4 GB of HBM2 on a 1024-bit bus, yielding 204.8 GB/s of bandwidth. That is lower than the RX 570’s 224.0 GB/s on GDDR5, but the HBM2 implementation achieves this with far less physical space and power. The Vega M GH also has a higher pixel rate (76.16 GPixel/s vs 39.81 GPixel/s) despite fewer ROPs (64 vs 32), which suggests it can handle fill-rate-bound tasks like high-resolution UI compositing or certain post-processing effects more efficiently. For a thin-and-light laptop or a compact mini-PC, the Vega M GH is the only viable option here.

Architecture Differences

Both GPUs use the same GCN 4.0 architecture and are fabricated on GlobalFoundries’ 14 nm process, but the underlying chips are distinct. The Vega M GH uses Polaris 22, a chip with 5,000 million transistors on a 208 mm² die, giving a transistor density of 24.0M/mm². The RX 570 uses Polaris 20, with 5,700 million transistors on a 232 mm² die, at a slightly higher density of 24.6M/mm². The extra 700 million transistors on the RX 570 go toward compute resources: 2,048 shading units, 128 TMUs, and 32 ROPs. The Vega M GH has 1,536 shading units, 96 TMUs, and 64 ROPs — the higher ROP count is a notable inversion, but it does not compensate for the compute shortfall.

Clock speeds also differ. The RX 570 runs at 1168 MHz base and 1244 MHz boost, while the Vega M GH is at 1063 MHz base and 1190 MHz boost. Memory is where the architectures diverge most sharply: the Vega M GH uses HBM2 at 800 MHz with a 1600 Mbps effective data rate on a 1024-bit bus, while the RX 570 uses GDDR5 at 1750 MHz with 7 Gbps effective on a 256-bit bus. The result is a bandwidth gap of 224.0 GB/s (RX 570) versus 204.8 GB/s (Vega M GH), but the Vega M GH achieves this with far fewer physical traces and less power. Both support DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RX 570 has a PCIe 3.0 x16 interface; the Vega M GH is an IGP with no external bus. The RX 570 also has a 241 mm dual-slot cooler with 1x 6-pin power and a 450 W suggested PSU, while the Vega M GH is "Portable Device Dependent" for display outputs and has no power connectors at all.

FAQ

Q: Which GPU has higher compute throughput?

Q: Does the Vega M GH have any memory advantage?

A: It uses HBM2 on a 1024-bit bus, which is a wider interface than the RX 570’s 256-bit GDDR5, but its bandwidth (204.8 GB/s) is still lower than the RX 570’s 224.0 GB/s.

Q: What is the power requirement difference?

A: The Vega M GH has a 100 W TDP and no power connectors, while the RX 570 has a 150 W TDP and requires a 1x 6-pin connector and a 450 W suggested PSU.

The Verdict

The data is unambiguous: the AMD Radeon RX 570 is the faster GPU by a wide margin. It wins both head-to-head benchmarks, with leads of 15.5% in OpenCL and 26.9% in Vulkan. Its compute resources are larger across the board — 2,048 shading units, 128 TMUs, and 5.095 TFLOPS FP32. For anyone building a desktop with a PCIe slot and a 450 W PSU, the RX 570 is the obvious choice. Its 4 GB GDDR5 on a 256-bit bus delivers more bandwidth (224.0 GB/s) and it has a full set of display outputs (1x DVI, 1x HDMI 2.0b, 3x DisplayPort 1.4a). The RX 570’s launch MSRP was 169 USD, and while it is end-of-life, its performance profile remains competitive in its class.

The Vega M GH is not a competitor to the RX 570; it is a solution to a different problem. As an IGP with a 100 W TDP, no power connectors, and no external bus, it exists for systems where a discrete GPU is physically impossible. Its HBM2 memory on a 1024-bit bus provides 204.8 GB/s of bandwidth in a compact package, and its pixel rate (76.16 GPixel/s) is actually higher than the RX 570’s. If the choice is between the Vega M GH and nothing, the Vega M GH is clearly better. But if the choice is between the Vega M GH and the RX 570, the benchmark results dictate one answer: the RX 570, by a significant margin. The Vega M GH’s 0 wins versus 2 losses in head-to-head testing is not a close call — it is a verdict.
