AMD Radeon Pro Vega II vs AMD Radeon RX 6650M Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall winner in direct comparison: the AMD Radeon Pro Vega II takes both available head-to-head tests, but the margin tells a more nuanced story about workload types. In Geekbench OpenCL, the Pro Vega II scores 99,048 against the RX 6650M's 65,800, a commanding 50.5% advantage. That is a massive gap, one that reflects the Pro Vega II's raw compute throughput and its place in the professional compute segment.

The Vulkan result is closer but still favors the Pro Vega II. It posts 99,621 versus 77,735 for the RX 6650M, a 28.2% lead. That narrower margin suggests that the RX 6650M's newer architecture helps it close some of the gap in modern graphics APIs, even if it cannot overcome the older card's sheer hardware resources.

Looking at the broader database averages, the Pro Vega II holds an average benchmark score of 109,617, which places it at the 94th percentile of all GPUs. The RX 6650M averages 71,768, sitting at the 91st percentile. The percentile difference is smaller than the raw score gap, indicating that both cards occupy the upper tier of recorded hardware, but the Pro Vega II is clearly further up the performance curve.

The Pro Vega II's closest rivals in the database include the AMD Radeon PRO W7900 at 110,725 (1% ahead), the NVIDIA RTX A5500 Mobile at 113,944 (3.8% ahead), and the AMD Radeon Pro W6600X at 107,342 (2.1% behind). The RX 6650M, by contrast, sits near the NVIDIA TITAN X Pascal at 72,098 (0.5% behind) and the AMD Radeon Pro Vega 64 at 72,379 (0.8% behind). This positioning confirms that the Pro Vega II competes with workstation-class hardware, while the RX 6650M trades blows with older enthusiast cards.

Where Each One Wins

The Pro Vega II is the clear pick for compute-heavy workloads. Its 50.5% OpenCL lead and 28.2% Vulkan lead indicate that applications leveraging raw GPU compute, such as rendering, simulation, or data processing, will see substantially better throughput on the Pro Vega II. The card also carries 32 GB of HBM2 memory on a 4096-bit bus, delivering 825.3 GB/s of bandwidth. That memory configuration is aimed squarely at large datasets and professional visualization tasks where capacity and bandwidth trump efficiency.

The RX 6650M, despite losing both head-to-head tests, has its own territory. It is built on RDNA 2.0 with 28 ray tracing cores, making it the only one of the two with dedicated hardware for ray-traced effects. Its support for DirectX 12 Ultimate (12_2) and Vulkan 1.4 gives it a modern API feature set that the Pro Vega II lacks. For gaming or applications that leverage DirectX 12 Ultimate features, the RX 6650M is the more capable option despite its lower raw compute numbers. Its 120 W TDP and IGP form factor also make it suitable for portable systems, whereas the Pro Vega II is a quad-slot card with an 850 W suggested power supply.

In short, the Pro Vega II wins on pure compute performance and memory bandwidth, while the RX 6650M wins on architectural modernity, ray tracing support, and power efficiency.

Specification Differences

The two cards differ in nearly every major specification category. The Pro Vega II uses 4096 shading units, 256 texture mapping units, and 64 ROPs. The RX 6650M has 1792 shading units, 112 TMUs, and 64 ROPs. The RX 6650M includes 28 ray tracing cores; the Pro Vega II has none.

Memory is another stark divide. The Pro Vega II ships with 32 GB of HBM2 across a 4096-bit bus, while the RX 6650M has 8 GB of GDDR6 on a 128-bit bus. Bandwidth figures reflect this: 825.3 GB/s for the Pro Vega II versus 224.0 GB/s for the RX 6650M.

Clock speeds favor the RX 6650M. Its base clock is 2068 MHz and boost clock is 2416 MHz, with a game clock of 2222 MHz. The Pro Vega II runs at 1574 MHz base and 1720 MHz boost. Memory clocks also differ: the RX 6650M runs at 1750 MHz (14 Gbps effective), while the Pro Vega II runs at 806 MHz (1612 Mbps effective).

Pixel and texture rates tell a mixed story. The RX 6650M has a higher pixel rate at 154.6 GPixel/s versus 110.1 GPixel/s for the Pro Vega II. The Pro Vega II counters with a 440.3 GTexel/s texture rate, well ahead of the RX 6650M's 270.6 GTexel/s.

Power and physical specs differ dramatically. The Pro Vega II is rated at 475 W TDP with a quad-slot form factor and an 850 W suggested power supply. The RX 6650M is rated at 120 W TDP, uses an integrated form factor (IGP), and requires no power connectors.

The bus interface also differs: the Pro Vega II uses Apple MPX, while the RX 6650M uses PCIe 4.0 x8. Display outputs are 1x HDMI 2.0b and 4x Thunderbolt for the Pro Vega II, versus portable-device-dependent outputs for the RX 6650M.

Architecture Differences

The Pro Vega II is built on the Vega 20 chip using GCN 5.1 architecture, fabricated on a 7 nm process at TSMC. It packs 13,230 million transistors on a 331 mm² die, giving a transistor density of 40.0 million per mm². The RX 6650M uses the Navi 23 chip with RDNA 2.0 architecture, also on TSMC's 7 nm node, with 11,060 million transistors on a 237 mm² die and a higher density of 46.7 million per mm².

The architecture generations reflect different design philosophies. GCN 5.1 is a mature compute-oriented design that scales well with large numbers of shading units and wide memory buses. RDNA 2.0 is a gaming-first architecture with a focus on efficiency, featuring 28 ray tracing cores and support for DirectX 12 Ultimate (12_2). The Pro Vega II supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3; the RX 6650M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

FP32 throughput favors the Pro Vega II at 14.09 TFLOPS versus 8.659 TFLOPS for the RX 6650M. FP16 numbers follow the same pattern: 28.18 TFLOPS for the Pro Vega II and 17.32 TFLOPS for the RX 6650M, both at a 2:1 ratio.

The production status for both cards is end-of-life. The Pro Vega II released in 2019 as part of the Radeon Pro Mac (Vega Series) generation, while the RX 6650M launched in 2022 in the Navi Mobile (RX 6000M) generation, succeeding Polaris Mobile. The Pro Vega II carries a launch MSRP of 2,199 USD, while no launch MSRP is recorded for the RX 6650M.
