AMD Radeon RX Vega M GH vs NVIDIA TITAN RTX Comparison

The data presents a stark contrast between two end-of-life graphics solutions: the NVIDIA TITAN RTX, a dual-slot 280 W add-in card, and the AMD Radeon RX Vega M GH, a 100 W integrated graphics processor. Across the two shared benchmark tests, the TITAN RTX records an average benchmark score of 31,676, placing it in the 76th percentile of all GPUs, while the Vega M GH averages 29,197, sitting just two percentile points lower at 74th. This narrow percentile gap, however, belies the massive performance chasm between them, as the TITAN RTX wins both head-to-head tests by margins exceeding 335%.

The Verdict

Based strictly on the benchmark data, the NVIDIA TITAN RTX is the decisive choice for any workload where raw compute and graphics throughput are the sole criteria. Its Geekbench OpenCL score of 144,858 is 434% higher than the AMD Radeon RX Vega M GH’s 27,125, and its Geekbench Vulkan score of 136,073 is 335.2% higher than the Vega M GH’s 31,268. With two wins out of two head-to-head tests, the TITAN RTX is categorically superior in every measurable shared test.

The AMD Radeon RX Vega M GH, while significantly slower, is not without a niche. Its 100 W TDP and IGP (integrated graphics processor) slot width indicate it is designed for portable or compact systems where the 280 W TDP and dual-slot footprint of the TITAN RTX are physically impractical. For users constrained by power and space, the Vega M GH offers a functional, if modest, graphics solution. However, the data offers no scenario where the Vega M GH outperforms the TITAN RTX in raw speed; its advantage is purely in its integration profile.

The decision is therefore not a matter of application or workload, but of form factor and power envelope. If a system can accommodate a 280 W, dual-slot, 267 mm card with a 600 W suggested PSU, the TITAN RTX is the only rational choice based on performance data. If the requirement is an embedded or space-constrained design, the Vega M GH is the available option, but with the understanding that its performance is a fraction of the discrete card’s.

Where Each One Wins

The NVIDIA TITAN RTX wins in every benchmark category where both products have data. In Geekbench OpenCL, the TITAN RTX delivers a score of 144,858, which is 434% higher than the Vega M GH’s 27,125. In Geekbench Vulkan, the TITAN RTX scores 136,073, a 335.2% improvement over the Vega M GH’s 31,268. These are not marginal victories; they represent a generational gulf in compute capability.

The AMD Radeon RX Vega M GH wins in no benchmark comparisons, as it has zero head-to-head victories. Its only advantage lies in its physical and power characteristics. With a 100 W TDP and an IGP slot width, it requires no dedicated power connectors and fits into a portable device's motherboard. The TITAN RTX, by contrast, requires 2x 8-pin power connectors and a 600 W suggested PSU. The Vega M GH’s "win" is therefore not a performance metric but a design constraint. It is the only option of the two for a system that lacks the space or power delivery for a discrete card.

Furthermore, the Vega M GH’s nearest rivals include the AMD Radeon RX 470 with a deltaPct of 0.7% and the AMD Radeon RX 6800M at 1.1%, indicating its performance sits in a similar bracket to those mobile and desktop parts. The TITAN RTX’s nearest rivals, such as the NVIDIA RTX PRO 4500 Blackwell with a deltaPct of 0.5%, show it competes with far more modern and powerful workstation cards. This positioning reinforces that the TITAN RTX is in a different performance league entirely.

Architecture Differences

The architectural divide between these two GPUs is substantial. The NVIDIA TITAN RTX is built on the Turing architecture using a TU102 chip fabricated on a 12 nm process at TSMC. It contains 18,600 million transistors on a 754 mm² die, yielding a transistor density of 24.7M per mm². In contrast, the AMD Radeon RX Vega M GH utilizes the GCN 4.0 architecture with a Polaris 22 chip, built on a 14 nm process at GlobalFoundries. This chip houses 5,000 million transistors on a 208 mm² die, with a transistor density of 24.0M per mm².

The TITAN RTX’s compute resources are vastly larger. It features 4,608 shading units, 288 texture mapping units (TMUs), and 96 render output units (ROPs). It also includes 72 RT cores and 576 tensor cores, which are absent entirely from the Vega M GH, which lists null values for both. The Vega M GH has 1,536 shading units, 96 TMUs, and 64 ROPs. This difference in raw hardware translates directly to the performance gap.

Clock speeds and memory architectures also differ. The TITAN RTX has a base clock of 1350 MHz and a boost clock of 1770 MHz, while the Vega M GH runs at 1063 MHz base and 1190 MHz boost. Memory is another major differentiator: the TITAN RTX uses 24 GB of GDDR6 on a 384-bit bus, achieving 672.0 GB/s bandwidth at 14 Gbps effective. The Vega M GH uses 4 GB of HBM2 on a 1024-bit bus, achieving 204.8 GB/s bandwidth at 1600 Mbps effective. The TITAN RTX’s FP32 throughput is 16.31 TFLOPS, while the Vega M GH manages 3.656 TFLOPS. The TITAN RTX also offers FP16 at 32.62 TFLOPS (2:1 rate), whereas the Vega M GH’s FP16 is 3.656 TFLOPS (1:1 rate).

Head-to-Head Benchmarks

The head-to-head data is limited to two tests, but both are decisive. In Geekbench OpenCL, the NVIDIA TITAN RTX scores 144,858 against the AMD Radeon RX Vega M GH’s 27,125. This is a deltaPct of 434%, meaning the TITAN RTX is over five times faster in this compute workload. This test likely reflects general-purpose GPU compute, where the TITAN RTX’s 4,608 shading units and 576 tensor cores provide overwhelming parallelism compared to the Vega M GH’s 1,536 shading units and lack of tensor cores.

In Geekbench Vulkan, the TITAN RTX scores 136,073 against the Vega M GH’s 31,268, a deltaPct of 335.2%. This graphics API test shows a similar, though slightly less extreme, margin. The TITAN RTX’s advantage here is likely driven by its higher clock speeds (1770 MHz boost vs. 1190 MHz boost) and vastly superior memory bandwidth (672.0 GB/s vs. 204.8 GB/s). The Vega M GH’s HBM2 memory, while on a wider 1024-bit bus, operates at a much lower effective speed of 1600 Mbps, which cannot compensate for the TITAN RTX’s 14 Gbps GDDR6.

The TITAN RTX also has additional benchmark data that the Vega M GH lacks, including a Passmark G3D score of 20,491 and a Geekbench Vulkan score of 136,073. While these cannot be directly compared, they provide context for the TITAN RTX’s overall capability. Its 3DMark Steel Nomad DX12 score of 3,794 and Passmark GPU Compute score of 10,034 further illustrate its strength in both gaming and compute scenarios. The Vega M GH’s lack of these results means its performance profile is less well-documented, but the two available tests are sufficient to establish a clear hierarchy.

Specification Differences

The specification sheets for these two GPUs diverge on nearly every major point. The most significant differences are in memory, compute units, and power. The NVIDIA TITAN RTX offers 24 GB of GDDR6, while the AMD Radeon RX Vega M GH has 4 GB of HBM2. The TITAN RTX’s memory bandwidth is 672.0 GB/s versus the Vega M GH’s 204.8 GB/s.
