AMD Radeon RX Vega M GH vs NVIDIA GeForce GTX 1630 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a clear overall victory for the AMD Radeon RX Vega M GH, which wins both available tests. The most decisive margin appears in the Geekbench Vulkan workload, where the AMD part scores 31,268 against the NVIDIA GeForce GTX 1630's 23,695, a 32% advantage. That is a substantial gap for a single API test, indicating that the Vega M GH has a significant edge in compute-heavy tasks that leverage Vulkan's low-level access.

In the Geekbench OpenCL test, the lead is narrower but still firmly in AMD's favor. The Radeon RX Vega M GH posts 27,125 while the GeForce GTX 1630 manages 24,858, resulting in a 9.1% delta. While not as dramatic as the Vulkan result, this still represents a consistent performance advantage across both recorded workloads. The data shows no scenario in the database where the GTX 1630 pulls ahead.

Looking at the broader context, the AMD part sits at the 74th percentile among all GPUs in the database, while the NVIDIA card sits at the 70th percentile. The average benchmark score for the Radeon RX Vega M GH is 29,197, compared to 24,277 for the GeForce GTX 1630. That is a difference of roughly 4,920 points, or about 20% higher for the AMD product.

The nearest rivals for each card put these numbers into perspective. The AMD Radeon RX Vega M GH sits within 1.1% of the AMD Radeon RX 6800M (average score 28,874) and within 0.7% of the AMD Radeon RX 470 (28,996). It essentially trades blows with the Intel Arc A370M (29,175, only 0.1% behind) and the AMD FirePro W8000 (29,211, effectively tied). For the NVIDIA side, the GeForce GTX 1630 is nearly identical to the GTX 780 Ti (24,236, 0.2% difference) and the RTX 2080 SUPER (24,170, 0.4% difference). It also sits close to the Radeon RX 6600 XT (24,442, 0.7% lower) and the RX 6800S (24,063, 0.9% higher). In other words, the AMD Vega M GH competes in a higher performance tier entirely, while the GTX 1630 lands among much older or lower-tier parts.

Where Each One Wins

The AMD Radeon RX Vega M GH wins in both recorded benchmark categories, so the use-case split is straightforward. The Vulkan result is particularly telling: a 32% lead suggests that applications or games that use Vulkan will see a pronounced advantage on the AMD side. The OpenCL result, while smaller, still shows a healthy 9.1% lead, meaning general-purpose GPU compute tasks that rely on OpenCL should also favor the Vega M GH.

For the NVIDIA GeForce GTX 1630, there are no benchmark wins in the database. However, this does not mean the card is without merit. Its 75 W TDP is lower than the AMD part's 100 W, which can matter in thermally constrained systems. Additionally, it is a single-slot card with no external power connectors, making it easier to drop into pre-existing builds with modest power supplies. The GTX 1630 also supports DirectX 12_1, while the Vega M GH only reaches DirectX 12_0, so titles that specifically require 12_1 features might behave differently, though no benchmark data exists to quantify this.

The GTX 1630's memory configuration uses GDDR6 across a 64-bit bus, delivering 96.00 GB/s of bandwidth. The AMD part uses HBM2 across a 1024-bit bus, delivering 204.8 GB/s, which is more than double. That bandwidth advantage likely explains much of the AMD card's compute lead, especially in Vulkan workloads that are sensitive to memory throughput.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon RX Vega M GH uses the Polaris 22 chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 5,000 million transistors into a 208 mm² die, giving a transistor density of 24.0M per mm². The NVIDIA GeForce GTX 1630 uses the TU117 chip based on Turing architecture, built on a 12 nm process at TSMC. It contains 4,700 million transistors on a 200 mm² die, with a density of 23.5M per mm². The two dies are similar in size, but AMD packs slightly more transistors into a slightly larger area.

The compute resources differ dramatically. The Radeon RX Vega M GH has 1,536 shading units, 96 texture mapping units, and 64 raster operations pipelines. The GTX 1630 has just 512 shading units, 32 TMUs, and 16 ROPs. That is a 3x difference in shading units and TMUs, and a 4x difference in ROPs, which explains the large performance gap. Pixel rate for the AMD card is 76.16 GPixel/s versus 28.56 GPixel/s for NVIDIA, and texture rate is 114.2 GTexel/s versus 57.12 GTexel/s.

Clock speeds tell a different story. The GTX 1630 runs at a base clock of 1740 MHz and boosts to 1785 MHz, while the Vega M GH is much lower at 1063 MHz base and 1190 MHz boost. Despite the lower clocks, the AMD card's massive resource advantage wins out. FP32 throughput is 3.656 TFLOPS for AMD versus 1.828 TFLOPS for NVIDIA, exactly a 2x difference. Interestingly, FP16 throughput is identical at 3.656 TFLOPS for both, but for different reasons: AMD achieves it with a 1:1 ratio, while NVIDIA uses a 2:1 ratio.

The AMD card is an integrated graphics processor (IGP) with a portable-device-dependent output, meaning it is designed for laptops or compact systems. The GTX 1630 is a discrete single-slot card measuring 145 mm in length, 69 mm in height, and 18 mm in width, with outputs including 1x DVI, 1x HDMI 2.0, and 1x DisplayPort 1.4a. The bus interface for NVIDIA is PCIe 3.0 x16, while AMD uses an integrated bus interface. The NVIDIA card supports Vulkan 1.4, while AMD supports Vulkan 1.3. Both support OpenGL 4.6.

The Verdict

The benchmark data is unambiguous: the AMD Radeon RX Vega M GH outperforms the NVIDIA GeForce GTX 1630 in every recorded test. The Vulkan score shows a 32% advantage, and the OpenCL score shows a 9.1% advantage. The average benchmark score difference is roughly 20% in favor of AMD. Anyone looking for raw compute performance should choose the Vega M GH.

However, the GTX 1630 has clear practical advantages. It is a discrete, single-slot card with a 75 W TDP and no power connectors, making it far easier to install in a standard desktop. It also offers newer API support with DirectX 12_1 and Vulkan 1.4. The Vega M GH, by contrast, is an integrated GPU with portable-device-dependent outputs, meaning it is not a drop-in upgrade path for a typical desktop.

The choice comes down to the system context. In a compact or integrated platform where the AMD IGP is available, the Vega M GH delivers superior performance with its massive memory bandwidth and compute resources. In a conventional desktop where a low-power, physically small discrete card is needed, the GTX 1630 is the more practical option, even if its performance is clearly lower. The data shows that the AMD part belongs to a higher performance tier, while the NVIDIA card trades performance for flexibility and ease of integration.
