NVIDIA PG506-232 vs NVIDIA RTX 6000D Comparison

The data presents a direct comparison between two very different NVIDIA professional cards: the PG506-232, a server-oriented Ampere part, and the RTX 6000D, a Blackwell workstation GPU. The benchmark results show a decisive victory for the newer architecture, but the specifications reveal that these are fundamentally different tools designed for different workloads. This analysis breaks down where each card excels and which one is the appropriate choice based on the data.

Head-to-Head Benchmarks

The only shared benchmark between the two cards is Geekbench OpenCL, and the results are not close. The NVIDIA RTX 6000D scores 388,405 points, while the NVIDIA PG506-232 scores 225,124 points. This represents a 42% delta in favor of the RTX 6000D, meaning the RTX 6000D is roughly 72% faster than the PG506-232 in this specific compute test. This is a massive generational leap, reflecting the fundamental architectural differences between the two cards.

While the RTX 6000D wins the only direct head-to-head test, the PG506-232 holds its own in the broader competitive landscape. The PG506-232's average benchmark score of 225,124 places it in the 99th percentile of all GPUs, which is higher than the RTX 6000D's 98th percentile. This is an important nuance. The PG506-232 is an extremely capable compute card in its own right, even if it is outpaced by the newer RTX 6000D. Looking at the PG506-232's nearest rivals, it is 2.4% ahead of the AMD Radeon PRO W7900D and 8.7% ahead of the NVIDIA A100 PCIe 80 GB. It trails the NVIDIA L20 by 10.4%. This shows the PG506-232 is a top-tier performer among its contemporaries.

The RTX 6000D's average score of 195,964 is actually lower than the PG506-232's average score, but this is a statistical artifact. The RTX 6000D's average is dragged down by its second benchmark, the 3DMark Steel Nomad DX12 test, where it scores 3,522 points. This is a gaming-oriented test, and the PG506-232 has no equivalent score, meaning the averages are not directly comparable across the two cards. In the only test where they meet, Geekbench OpenCL, the RTX 6000D is the clear winner. The RTX 6000D's nearest rivals further contextualize its performance: it is 0.8% ahead of the Tesla V100S PCIe 32 GB, 4.7% ahead of the A100 SXM4 40 GB, and 6.1% ahead of the RTX 5000 Ada Generation. However, it is 5.4% behind the A100 PCIe 80 GB. This suggests the RTX 6000D's performance profile is strong but not uniformly dominant against the previous generation's top-tier compute cards.

The Verdict

The choice between these two cards is clear-cut based on the data. The NVIDIA RTX 6000D is the superior performer in raw compute, as evidenced by its 42% lead in the Geekbench OpenCL test. It also offers a massive generational leap in specifications, with a newer architecture, more memory, and higher clock speeds. For any workload that relies on FP32 compute, the RTX 6000D is the definitive choice.

The NVIDIA PG506-232, despite being an older card, is not without merit. Its 99th percentile ranking shows it remains a highly capable compute accelerator. It is a low-power, server-oriented part (165 W TDP) that was designed for specific professional workloads where its HBM2 memory and high transistor density are beneficial. It is not a direct replacement for the RTX 6000D, but rather a different tool for a different job. If a user is looking for maximum compute performance in a professional workstation and has the power budget (600 W TDP) and the budget for the 8,565 USD launch MSRP, the RTX 6000D is the only logical choice. If the workload is constrained by power and requires a specific server form factor, the PG506-232 remains a viable, end-of-life option.

Specification Differences

The two cards differ in nearly every major specification category. The RTX 6000D is built on a newer 5 nm process node, while the PG506-232 uses a 7 nm node. The RTX 6000D has a significantly higher base clock of 1992 MHz and boost clock of 2430 MHz, compared to the PG506-232's 930 MHz base and 1440 MHz boost. The RTX 6000D also has a much larger memory capacity of 84 GB of GDDR7, while the PG506-232 has 24 GB of HBM2. The bus interface also differs, with the RTX 6000D using PCIe 5.0 x16 and the PG506-232 using PCIe 4.0 x16. The RTX 6000D has a much higher TDP of 600 W with a 1x 16-pin power connector, while the PG506-232 has a 165 W TDP and an 8-pin EPS connector. The RTX 6000D also features 4x DisplayPort 2.1b outputs, whereas the PG506-232 has no display outputs. Finally, the RTX 6000D is 304 mm long, while the PG506-232 is 267 mm long.

Architecture Differences

The architectural differences are profound and explain the performance disparity. The PG506-232 is based on the Ampere architecture with the GA100 chip, which is a compute-focused design with 54,200 million transistors on a 826 mm² die. In contrast, the RTX 6000D uses the Blackwell 2.0 architecture with the GB202 chip, containing 92,200 million transistors on a slightly smaller 750 mm² die. This results in a much higher transistor density for the RTX 6000D (122.9M / mm²) versus the PG506-232 (65.6M / mm²). The RTX 6000D also has a massive advantage in core counts, with 19,968 shading units, 624 TMUs, and 192 ROPs, compared to the PG506-232's 3,584 shading units, 224 TMUs, and 96 ROPs. The RTX 6000D also has 156 dedicated RT cores and 624 tensor cores, while the PG506-232 has no RT cores and 224 tensor cores. This makes the RTX 6000D a much more versatile processor, capable of handling graphics and ray tracing workloads that the PG506-232 cannot. The RTX 6000D also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 APIs, while the PG506-232 has no listed API support.

Where Each One Wins

The RTX 6000D wins in every measurable benchmark and in most practical use cases. Its 97.04 TFLOPS FP32 performance, versus the PG506-232's 10.32 TFLOPS, makes it the dominant choice for any general-purpose compute task, including AI training, scientific simulation, and complex 3D rendering. Its 1.40 TB/s memory bandwidth and 84 GB of VRAM provide a significant advantage for large datasets and high-resolution textures. The RTX 6000D is also the only card with display outputs and ray tracing support, making it a true workstation GPU that can handle both compute and graphics workloads. Its 156 RT cores enable hardware-accelerated ray tracing, a feature entirely absent from the PG506-232.

The PG506-232's wins are more situational and tied to its specific design. Its primary advantage is its efficiency: a 165 W TDP versus the RTX 6000D's 600 W TDP. This makes it suitable for dense server deployments where power and cooling are limited. Its 933.1 GB/s of bandwidth and 3072-bit memory bus make it a capable card for memory-bandwidth-sensitive workloads from the Ampere generation. Its 99th percentile ranking indicates it is a top-tier compute card, but it is clearly outclassed by the newer RTX 6000D in raw performance. The PG506-232 is a specialist tool for a specific era of server compute, whereas the RTX 6000D is a general-purpose powerhouse for the current generation of professional workstations.
