AMD Radeon Pro W6600M vs NVIDIA RTX A2000 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall win for the NVIDIA RTX A2000 in the only two shared tests, with the AMD Radeon Pro W6600M trailing in both. The largest gap appears in Geekbench OpenCL, where the RTX A2000 scores 67,695 against the W6600M’s 56,140. That is a 17.1% deficit for the AMD part, a substantial margin in raw compute workloads that rely on OpenCL acceleration.

The second shared test, Geekbench Vulkan, is much closer. The RTX A2000 posts 69,089, while the W6600M reaches 67,652, a delta of only 2.1%. In practical terms, this means the AMD card is nearly competitive in Vulkan-based applications, but the NVIDIA card still takes the win. Across both benchmarks, the RTX A2000 wins 2 out of 2 head-to-head matchups.

Looking at the broader database context, the W6600M’s average benchmark score is 61,896, which places it in the 89th percentile of all GPUs. Its nearest rivals include the AMD Radeon 8050S at 62,108 (0.3% ahead), the NVIDIA GeForce RTX 4090 at 60,347 (the W6600M is 2.6% ahead), the Intel Arc Pro A60 at 60,326 (2.6% ahead), and the AMD Radeon Pro Vega 48 at 60,140 (2.9% ahead). So despite losing the head-to-head, the W6600M sits in strong company, outperforming several desktop and workstation parts in the database’s aggregate scoring.

The RTX A2000’s average benchmark score is 46,043, which is lower than the W6600M’s average, yet it still lands in the 85th percentile. That discrepancy is explained by the fact that the RTX A2000’s average includes the 3DMark Steel Nomad DX12 result of 1,345, which drags down its aggregate. Its nearest rivals include the NVIDIA RTX 5880 Ada Generation at 45,972 (0.2% ahead), the Intel Arc A730M at 45,592 (the A2000 is 1% ahead), the AMD Radeon RX 5600M at 46,601 (1.2% behind), and the Intel Arc A530M at 46,614 (1.2% behind). The A2000’s average is tightly clustered with these parts, meaning its overall position is more about consistency across different test types than raw peak performance.

The key takeaway from the head-to-head data is that the RTX A2000 is faster in both measured APIs, but the margin varies wildly. OpenCL separates them by nearly a fifth, while Vulkan is essentially a tie for practical purposes. If a workload is Vulkan-bound, the two cards are nearly interchangeable; if it is OpenCL-bound, the NVIDIA card has a decisive edge.

Architecture Differences

The two GPUs come from different foundries and process nodes. The AMD Radeon Pro W6600M uses the Navi 23 chip built on TSMC’s 7 nm process, with 11,060 million transistors packed into a 237 mm² die, yielding a transistor density of 46.7 million per square millimeter. The NVIDIA RTX A2000 uses the GA106 chip on Samsung’s 8 nm process, with 12,000 million transistors on a 276 mm² die, for a density of 43.5 million per square millimeter. The AMD chip is smaller, denser, and built on a more advanced node, which helps explain its lower power draw despite similar performance per watt.

Architecturally, the W6600M is RDNA 2.0, part of the Radeon Pro Mobile generation. The RTX A2000 is Ampere, from the Workstation Ampere family. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical on paper.

The shading resources differ significantly. The W6600M has 1,792 shading units, 112 texture mapping units, and 64 ROPs. The RTX A2000 has 3,328 shading units, 104 TMUs, and 48 ROPs. The NVIDIA part has nearly double the shader count, but fewer TMUs and ROPs. That explains why the A2000’s pixel rate is 57.60 GPixel/s versus the W6600M’s 130.2 GPixel/s, and why the texture rate is 124.8 GTexel/s versus 227.8 GTexel/s. The AMD card is built for higher fill-rate throughput, while the NVIDIA card leans on shader compute.

Ray tracing resources are close: the W6600M has 28 RT cores, the A2000 has 26. Tensor cores are the big differentiator here. The RTX A2000 has 104 tensor cores, while the W6600M has none listed. That means the NVIDIA card can accelerate AI and DLSS-style workloads, while the AMD card cannot. For FP16 compute, the W6600M hits 14.58 TFLOPS using a 2:1 ratio, while the A2000 does 7.987 TFLOPS at a 1:1 ratio. The AMD card has a clear lead in half-precision throughput, but only if the software can use the 2:1 mode.

FP32 peak is slightly in the NVIDIA card’s favor: 7.987 TFLOPS versus 7.290 TFLOPS. That is a 9.6% advantage for the A2000 in raw single-precision math, which aligns with its OpenCL win. The clock speeds tell the story: the W6600M boosts to 2034 MHz, while the A2000 boosts to only 1200 MHz. The AMD card’s higher clocks compensate for fewer shaders, but not enough to overcome the A2000’s shader count in compute-heavy tests.

Where Each One Wins

The data suggests a clear split by workload type. The NVIDIA RTX A2000 wins in OpenCL, which is the dominant API for many professional compute tasks such as rendering, simulation, and some machine learning inference. Its 17.1% lead in that test is the single biggest performance gap between the two cards. If a user’s software stack is OpenCL-based, the A2000 is the safer choice.

The Vulkan result is much closer, with the A2000 leading by only 2.1%. That means in Vulkan-native applications, such as certain game engines, CAD viewports, or newer renderers, the two cards perform almost identically. The W6600M’s higher pixel rate (130.2 GPixel/s) and texture rate (227.8 GTexel/s) suggest it would do well in fill-rate-bound scenarios, like high-resolution viewport rendering or multi-sample anti-aliasing, even if the aggregate benchmarks do not isolate those workloads.

The RTX A2000’s tensor cores give it a distinct advantage in any AI-accelerated task, from denoising to neural network inference. The W6600M has no such hardware. For FP16 workloads, the W6600M is the stronger card on paper, with 14.58 TFLOPS versus 7.987 TFLOPS, but that advantage only materializes if the application explicitly uses the 2:1 FP16 path. Many professional tools still default to FP32.

Memory bandwidth favors the NVIDIA card: 288.0 GB/s versus 224.0 GB/s, a 28.6% advantage. The A2000 also has a wider 192-bit bus versus 128-bit, despite having less total memory (6 GB versus 8 GB). For large datasets that fit within 6 GB, the A2000 will move data faster. The W6600M’s extra 2 GB is useful for larger scenes or models that exceed 6 GB, but it comes with lower bandwidth.

Specification Differences

The two cards differ in several key fields. The process node is 7 nm (TSMC) for the AMD part, 8 nm (Samsung) for the NVIDIA part. Transistor count is 11,060 million versus 12,000 million, die size is 237 mm² versus 276 mm², and transistor density is 46.7M/mm² versus 43.5M/mm². Base clocks are 1224 MHz versus 562 MHz, boost clocks are 2034 MHz versus 1200 MHz, and memory clocks are 1750 MHz (14 Gbps effective) versus 1500 MHz (12 Gbps effective).

Memory size is 8 GB GDDR6 versus 6 GB GDDR6, bus width is 128-bit versus 192-bit, and bandwidth is 224.0 GB/s versus 288.0 GB/s. Shading units are 1,792 versus 3,328, TMUs are 112 versus 104, ROPs are 64 versus 48, RT cores are 28 versus 26, and tensor cores are none versus 104. Pixel rate is 130.2 GPixel/s versus 57.60 GPixel/s, texture rate is 227.8 GTexel/s versus 124.8 GTexel/s, FP32 is 7.290 TFLOPS versus 7.987 TFLOPS, and FP16 is 14.58 TFLOPS (2:1) versus 7.987 TFLOPS (1:1).

TDP is 90 W versus 70 W. The W6600M is an integrated form factor (IGP) with no power connectors, while the A2000 is a dual-slot card with no power connectors and a suggested PSU of 250 W. The A2000 has four mini-DisplayPort 1.4a outputs, while the W6600M’s outputs are portable device dependent. The A2000 is 167 mm long and 69 mm tall; the W6600M has no listed dimensions. Release dates are 2021-06-07 for the AMD part and 2021-08-09 for the NVIDIA part. Both are end-of-life. The A2000 had a launch MSRP of 449 USD.

The Verdict

The data points to a straightforward conclusion for most users. The NVIDIA RTX A2000 is the better choice for OpenCL-bound professional workloads, where its 17.1% lead is decisive. It also offers tensor cores, lower power draw (70 W versus 90 W), higher memory bandwidth, and a compact dual-slot form factor with four mini-DisplayPort outputs. Its aggregate score is lower, but that is an artifact of the 3DMark Steel Nomad DX12 result, which is not representative of its workstation strengths.

The AMD Radeon Pro W6600M is the better pick if you need more memory (8 GB versus 6 GB), higher fill-rate throughput (130.2 GPixel/s versus 57.60 GPixel/s), or if your software runs on Vulkan, where the performance gap shrinks to 2.1%. Its FP16 throughput is nearly double the A2000’s, provided the application uses the 2:1 path. It also has a higher percentile ranking (89th versus 85th) and outperforms several notable rivals in the database, including the RTX 4090 and the Arc Pro A60.

For a workstation that runs mixed professional tools, the RTX A2000 is the safer bet due to its OpenCL dominance and AI capabilities. For a compact, low-power mobile or embedded system where Vulkan is the primary API and 8 GB of VRAM is needed, the W6600M is a legitimate alternative. The recorded benchmarks show no scenario where the W6600M wins outright, so the A2000 is the default recommendation unless a specific workload favors the AMD card’s strengths.
