AMD Radeon RX Vega 11 vs NVIDIA RTX A2000 Mobile Comparison

The AMD Radeon RX Vega 11 is an integrated graphics processor from 2019, while the NVIDIA RTX A2000 Mobile is a dedicated laptop GPU from 2021. Benchmark data shows a decisive overall victory for the NVIDIA part, which won both head-to-head tests by substantial margins. The RTX A2000 Mobile’s average benchmark score of 13821 sits just below the Vega 11’s 14385, but that aggregate figure masks a massive performance gulf in compute workloads, where the NVIDIA GPU’s dedicated memory and Ampere architecture produce results that are categorically different from the AMD IGP.

Head-to-Head Benchmarks

The two available direct comparisons are Geekbench compute tests, and the NVIDIA RTX A2000 Mobile wins both by overwhelming margins. In Geekbench OpenCL, the RTX A2000 Mobile scores 56518 against the Vega 11’s 12525, a delta of -77.8% from the AMD part’s perspective. That means the NVIDIA GPU delivers roughly 4.5 times the OpenCL performance of the AMD IGP. The result is not close to parity; it is a generational gap that reflects the fundamental differences between a 15 W integrated solution and a 95 W dedicated mobile GPU.

Geekbench Vulkan tells a similar story, though the gap narrows slightly. The RTX A2000 Mobile posts 53146, while the Vega 11 manages 13543, yielding a delta of -74.5%. Even at its best showing relative to the NVIDIA part, the AMD IGP still trails by nearly three-quarters in raw compute throughput. The Vega 11’s Vulkan score of 13543 is actually higher than its OpenCL result of 12525, suggesting the GCN 5.0 architecture handles Vulkan workloads with slightly better efficiency, but that advantage is meaningless against a GPU that more than quadruples both scores.

Interpreting these numbers through the nearestRivals data adds context. The RTX A2000 Mobile’s average score of 13821 places it within 0.1% of the AMD Radeon 660M (13812) and 0.6% ahead of the AMD Radeon RX 7900 XT (13745). That last comparison is striking: the RTX A2000 Mobile edges out a flagship desktop card in average benchmark score, though the delta is small enough to be within noise. Meanwhile, the Vega 11’s average of 14385 puts it 0.1% behind the NVIDIA GeForce GTX 965M (14404) and 0.5% ahead of the Intel Iris Xe MAX Graphics (14315). The AMD IGP is competitive with older mid-range mobile GPUs, but it cannot touch the dedicated Ampere part.

Where Each One Wins

The NVIDIA RTX A2000 Mobile wins every head-to-head benchmark listed, so there is no test category where the AMD Radeon RX Vega 11 comes out ahead. The NVIDIA GPU’s wins span both OpenCL and Vulkan compute, which are the only direct comparisons available. For workloads that rely on general-purpose GPU compute—such as OpenCL-based rendering, physics simulation, or Vulkan compute shaders—the RTX A2000 Mobile is the clear choice. Its 8.637 TFLOPS of FP32 performance and 8.637 TFLOPS of FP16 performance (at 1:1 ratio) provide a level of throughput that the Vega 11’s 1.971 TFLOPS FP32 and 3.942 TFLOPS FP16 (2:1) cannot approach.

The AMD Radeon RX Vega 11’s only “win” is in the aggregate average benchmark score, where its 14385 edges out the RTX A2000 Mobile’s 13821. That difference is driven by the fact that the Vega 11 has three Geekbench scores (Metal, OpenCL, Vulkan) while the RTX A2000 Mobile has nine PassMark scores plus two Geekbench scores. The PassMark DirectX 9/10/11/12 results for the RTX A2000 Mobile are very low (115, 57, 68, and 47 respectively), likely reflecting driver or workload characteristics that drag down its average. For legacy DirectX workloads, the Vega 11’s higher average might suggest an edge, but there is no direct head-to-head data to confirm this.

For gaming, the RTX A2000 Mobile’s dedicated 4 GB of GDDR6 memory with 192.0 GB/s bandwidth versus the Vega 11’s system-shared memory is a decisive advantage. The Vega 11’s pixel rate of 11.20 GPixel/s and texture rate of 61.60 GTexel/s are dwarfed by the NVIDIA part’s 80.98 GPixel/s and 135.0 GTexel/s. The RTX A2000 Mobile also has hardware ray tracing cores (20) and tensor cores (80), which are entirely absent from the AMD IGP.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The AMD Radeon RX Vega 11 uses the Picasso chip with GCN 5.0 architecture, built on a 12 nm process at GlobalFoundries. The chip contains 4,940 million transistors on a 210 mm² die, yielding a transistor density of 23.5M per mm². In contrast, the NVIDIA RTX A2000 Mobile uses the GA107 chip with Ampere architecture, fabricated on Samsung’s 8 nm process. This chip packs 8,700 million transistors into a slightly smaller 200 mm² die, achieving a much higher density of 43.5M per mm².

Core configuration differences are stark. The Vega 11 has 704 shading units, 44 texture mapping units, and 8 ROPs. The RTX A2000 Mobile has 2,560 shading units, 80 TMUs, and 48 ROPs. The NVIDIA GPU also includes 20 ray tracing cores and 80 tensor cores, features that the AMD part lacks entirely. Clock speeds favor the NVIDIA GPU as well: the RTX A2000 Mobile runs at a base of 1215 MHz and boosts to 1687 MHz, while the Vega 11 has a 300 MHz base and 1400 MHz boost.

Memory architecture is fundamentally different. The Vega 11 uses system-shared memory with system-dependent bandwidth, meaning its performance scales with the host system’s RAM. The RTX A2000 Mobile has 4 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 192.0 GB/s of bandwidth. The memory clock is 1500 MHz with 12 Gbps effective transfer rate. This dedicated memory is a primary reason for the NVIDIA GPU’s massive compute advantage, as it does not compete with the CPU for bandwidth.

Power and interface differences are equally significant. The Vega 11 is an IGP with a 15 W TDP and no power connectors, while the RTX A2000 Mobile is a 95 W part that also has no power connectors but connects via PCIe 4.0 x16. The Vega 11’s bus interface is simply “IGP,” meaning it communicates through the motherboard. API support also differs: the Vega 11 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, while the RTX A2000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data points to a single conclusion: the NVIDIA RTX A2000 Mobile is the superior GPU for any compute-intensive task. Its head-to-head wins in OpenCL (56518 vs 12525) and Vulkan (53146 vs 13543) are not marginal—they represent a 77.8% and 74.5% advantage, respectively. The dedicated 4 GB GDDR6 memory with 192.0 GB/s bandwidth, combined with 2,560 shading units and 8.637 TFLOPS of FP32 throughput, makes it suitable for professional workloads like ray tracing, tensor-based AI inference, and high-resolution rendering that the Vega 11 cannot handle.

The AMD Radeon RX Vega 11 is not without merit, but its strengths are limited to specific contexts. Its 15 W TDP makes it suitable for thin-and-light laptops where power efficiency is paramount, and its system-shared memory means no dedicated VRAM allocation is needed. Its average benchmark score of 14385 is higher than the RTX A2000 Mobile’s 13821, but that figure is skewed by the different benchmark suites used for each GPU. For legacy DirectX workloads, the Vega 11’s higher average may indicate acceptable performance, but there is no direct head-to-head evidence to support a win.

For anyone choosing between these two, the decision hinges on workload. If the task involves modern compute APIs, ray tracing, or any GPU-accelerated professional application, the RTX A2000 Mobile is the only rational choice. If the priority is an integrated solution with minimal power draw and the workload is limited to basic graphics or older DirectX titles, the Vega 11 can suffice. Given the RTX A2000 Mobile’s 95 W TDP versus the Vega 11’s 15 W, the NVIDIA part requires a system designed for dedicated GPUs, but the performance payoff is undeniable. The benchmark data is unambiguous: the RTX A2000 Mobile wins both head-to-head tests by margins that exceed three-quarters, and its architecture offers features—ray tracing, tensor cores, dedicated memory—that the Vega 11 simply does not have.
