AMD Radeon Vega 11 vs NVIDIA RTX A2000 Mobile Comparison

The AMD Radeon Vega 11 and NVIDIA RTX A2000 Mobile represent two fundamentally different approaches to mobile graphics: one is a power-sipping integrated processor from 2019, the other a dedicated workstation-oriented GPU from 2021. The benchmark data shows a stark performance chasm, but the story is more nuanced than raw scores alone, as the Vega 11’s efficiency and the RTX A2000 Mobile’s feature set tell different tales.

Head-to-Head Benchmarks

The head-to-head results are decisively one-sided. In the Geekbench OpenCL test, the NVIDIA RTX A2000 Mobile scores 56,518, dwarfing the AMD Radeon Vega 11’s 13,392. This represents a 76.3% deficit for the AMD part, meaning the RTX A2000 Mobile delivers over four times the compute throughput in this cross-platform API. The Vulkan results tell a nearly identical story: the RTX A2000 Mobile posts 53,146 versus the Vega 11’s 12,273, a 76.9% gap. In both tests, the NVIDIA part wins with a margin that is not incremental but transformative.

These aren’t borderline victories. The data shows the RTX A2000 Mobile is in a completely different performance tier. For context, the Vega 11’s average benchmark score across all tests is 14,352, placing it at the 56th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce GTX TITAN, scores 14,373, a mere 0.1% difference. The RTX A2000 Mobile, by contrast, averages 13,821 across its broader test suite, sitting at the 55th percentile, with its closest competitor being the AMD Radeon 660M at 13,812 (0.1% delta). Despite the RTX A2000 Mobile’s massive wins in the head-to-head tests, its overall average is dragged down by other benchmarks, showing that its dominance is not uniform across all workloads.

Architecture Differences

The architectural divide is enormous. The AMD Radeon Vega 11 is built on GlobalFoundries’ 12 nm process, packing 4,940 million transistors into a 210 mm² die. Its transistor density is 23.5 million per square millimeter. In contrast, the NVIDIA RTX A2000 Mobile uses Samsung’s 8 nm node, housing 8,700 million transistors in a slightly smaller 200 mm² die, achieving a density of 43.5 million per square millimeter—nearly double. This density advantage is a direct enabler of the NVIDIA part’s higher compute throughput.

The compute configurations are worlds apart. The Vega 11 fields 704 shading units, 44 texture mapping units, and just 8 raster output pipelines. The RTX A2000 Mobile counters with 2,560 shaders, 80 TMUs, and 48 ROPs. This translates to a theoretical peak of 1.971 TFLOPS for FP32 on the AMD part versus 8.637 TFLOPS on the NVIDIA part—a 4.4x raw advantage. The RTX A2000 Mobile also boasts dedicated hardware the Vega 11 lacks entirely: 20 RT cores for ray tracing and 80 Tensor cores for AI acceleration. Furthermore, the NVIDIA part’s FP16 throughput matches its FP32 at 8.637 TFLOPS (1:1), while the AMD part’s FP16 is halved to 3.942 TFLOPS (2:1). The RTX A2000 Mobile supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Vega 11 is limited to DirectX 12 (12_1) and Vulkan 1.3.

Where Each One Wins

The RTX A2000 Mobile wins outright in raw compute, but the Vega 11 has its own territory. The AMD part integrates directly into the system as an IGP, meaning its memory bandwidth is "System Dependent," sharing system RAM. This makes it a zero-cost addition to a laptop, drawing a mere 15 W of power. The RTX A2000 Mobile, however, is a 95 W part with 4 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 192.0 GB/s of bandwidth. For memory-bound tasks, the NVIDIA part’s dedicated VRAM is a clear advantage, as the Vega 11’s bandwidth is entirely contingent on the host system’s memory configuration.

For workloads leveraging ray tracing or AI features, the RTX A2000 Mobile is the only option. The Vega 11 has no RT or Tensor cores, so any application using DXR or DLSS-style acceleration will either fail to run or run on the CPU. Conversely, the Vega 11’s low power draw and IGP nature make it suitable for ultra-light, fanless or passively-cooled designs where the RTX A2000 Mobile’s 95 W TDP would be impossible to manage. The data also shows the Vega 11’s nearest rivals include the Intel Iris Xe MAX Graphics, with a score of 14,315 (0.3% delta), indicating it is competitive with entry-level discrete options from the same era.

The Verdict

Strictly from the data, the NVIDIA RTX A2000 Mobile is the superior performer for any computationally intensive task. Its 76.3% lead in OpenCL and 76.9% lead in Vulkan are not close calls. For users running professional 3D rendering, scientific compute, or modern game engines that utilize DirectX 12 Ultimate features, the RTX A2000 Mobile is the only choice. The presence of RT and Tensor cores further cements its position for future-proofed workloads.

However, the AMD Radeon Vega 11 is not without merit. Its 15 W TDP is a fraction of the NVIDIA part’s 95 W, and its integrated nature means no additional cost or space in a system. For basic 2D desktop acceleration, video playback, and light, older games, the Vega 11’s 1.971 TFLOPS is sufficient. The benchmark data shows it holds a 56th percentile ranking, which is respectable for an IGP. The choice is clear: the RTX A2000 Mobile for performance, the Vega 11 for efficiency and simplicity. There is no middle ground in the data.
