NVIDIA PG506-232 vs NVIDIA RTX 6000 Ada Generation Comparison

NVIDIA’s RTX 6000 Ada Generation and PG506-232 are both end-of-life workstation and server accelerators, but they occupy different tiers of the performance spectrum. The data shows a clear overall winner in the RTX 6000 Ada, which leads the only shared benchmark by a substantial margin, yet the PG506-232 retains distinct advantages in power efficiency and physical footprint that matter for specific deployments.

Head-to-Head Benchmarks

The sole direct comparison available is the Geekbench OpenCL test, and the result is decisive. The RTX 6000 Ada Generation scores 311,629, while the PG506-232 scores 225,124. That translates to a 38.4% advantage for the RTX 6000 Ada, a massive gap that underscores the generational leap between the two architectures. In practical terms, this means the RTX 6000 Ada completes compute workloads nearly 1.4 times faster than the PG506-232 in this test.

Context from the nearest rivals reinforces this gap. The RTX 6000 Ada’s average benchmark score is 287,237, placing it 1.1% ahead of the NVIDIA L40 (284,111) and 14.4% ahead of the NVIDIA L20 (251,147). It trails the AMD Instinct MI300X (317,994) by 9.7% and the NVIDIA L40S (295,763) by 2.9%. The PG506-232, by contrast, averages 225,124, which is 2.4% ahead of the AMD Radeon PRO W7900D (219,827) and 8.7% ahead of the NVIDIA A100 PCIe 80 GB (207,124). However, it falls 10.4% behind the NVIDIA L20 (251,147) and 14.9% behind the NVIDIA RTX 6000D (195,964). The RTX 6000 Ada’s lead over the PG506-232 is therefore not just a matter of one benchmark; it reflects a fundamental performance tier difference, with the Ada card competing against top-tier accelerators while the PG506-232 sits closer to mid-range options.

The RTX 6000 Ada also wins the Vulkan benchmark with a score of 262,845, though the PG506-232 has no recorded Vulkan result, so this cannot be compared directly. Still, the OpenCL delta alone is sufficient to establish the RTX 6000 Ada as the superior compute performer in this pairing.

Architecture Differences

The RTX 6000 Ada is built on the Ada Lovelace architecture using the AD102 chip, manufactured on a 5 nm process at TSMC. It packs 76,300 million transistors into a 609 mm² die, yielding a transistor density of 125.3 million per mm². The PG506-232, in contrast, uses the Ampere architecture with the GA100 chip, built on a 7 nm process. It contains 54,200 million transistors on a larger 826 mm² die, resulting in a lower density of 65.6 million per mm². The newer process node gives the RTX 6000 Ada a significant efficiency and density advantage.

The RTX 6000 Ada features 18,176 shading units, 568 texture mapping units, and 192 ROPs. It also includes 142 ray tracing cores and 568 tensor cores. The PG506-232 is far more modest, with only 3,584 shading units, 224 TMUs, and 96 ROPs. It has no dedicated ray tracing cores (the field is null), but it does include 224 tensor cores. The RTX 6000 Ada’s shading unit count is over five times higher, which directly explains its superior FP32 compute throughput.

Memory architectures also differ fundamentally. The RTX 6000 Ada uses 48 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The PG506-232 uses 24 GB of HBM2 memory on a wider 3072-bit bus, achieving 933.1 GB/s. Despite the wider bus, the PG506-232’s bandwidth is slightly lower due to slower effective memory clock speeds (2.4 Gbps vs. 20 Gbps). The RTX 6000 Ada also has a higher base clock (915 MHz vs. 930 MHz, interestingly the PG506-232 has a slightly higher base) but a much higher boost clock (2505 MHz vs. 1440 MHz), which drives most of its performance advantage.

Specification Differences

The two cards diverge across nearly every specification. The RTX 6000 Ada has a 5 nm process node versus the PG506-232’s 7 nm. Transistor count is 76,300 million for the RTX 6000 Ada and 54,200 million for the PG506-232. Die size is 609 mm² versus 826 mm², meaning the RTX 6000 Ada packs more transistors into a smaller area. Transistor density is 125.3M/mm² versus 65.6M/mm².

Clock speeds differ significantly: the RTX 6000 Ada has a base clock of 915 MHz and a boost of 2505 MHz, while the PG506-232 has a base of 930 MHz and a boost of 1440 MHz. Memory capacity is 48 GB (GDDR6) versus 24 GB (HBM2). Bus width is 384-bit versus 3072-bit. Memory bandwidth is 960.0 GB/s versus 933.1 GB/s. The RTX 6000 Ada has 18,176 shading units versus 3,584, 568 TMUs versus 224, 192 ROPs versus 96, 142 ray tracing cores versus none, and 568 tensor cores versus 224.

Power and physical specs also differ: the RTX 6000 Ada has a TDP of 300 W with a 1x 16-pin power connector and a suggested PSU of 700 W. The PG506-232 has a TDP of 165 W with an 8-pin EPS connector and a suggested PSU of 450 W. Both are dual-slot and identical in dimensions (267 mm length, 112 mm height). The RTX 6000 Ada has 4x DisplayPort 1.4a outputs, while the PG506-232 has no display outputs. API support also differs: the RTX 6000 Ada supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the PG506-232 has no recorded API support.

The Verdict

The benchmark data is unambiguous: the RTX 6000 Ada Generation is the superior performer, winning the only head-to-head test by 38.4% and posting an average score 27.6% higher than the PG506-232. Its lead over the PG506-232 is larger than its deficit to the top-tier AMD Instinct MI300X (-9.7%) and comparable to its advantage over the NVIDIA L40 (+1.1%). For any compute workload where raw performance is the priority, the RTX 6000 Ada is the clear choice.

However, the PG506-232 is not without purpose. Its 165 W TDP is nearly half the RTX 6000 Ada’s 300 W, and its suggested PSU requirement of 450 W is substantially lower than 700 W. For dense server environments where power draw and thermal output are constrained, the PG506-232 offers a more efficient footprint. It also retains a 99th percentile ranking, so it is far from a weak card—it simply competes in a lower performance tier. The RTX 6000 Ada’s 48 GB memory capacity also doubles the PG506-232’s 24 GB, which is critical for large model inference or massive datasets. Ultimately, the RTX 6000 Ada wins on every performance metric, while the PG506-232 wins on power efficiency and lower system requirements.

Where Each One Wins

The RTX 6000 Ada Generation is the winner for any application that demands maximum compute throughput. Its 91.06 TFLOPS FP32 performance dwarfs the PG506-232’s 10.32 TFLOPS, making it ideal for high-fidelity rendering, complex simulation, and AI training workloads. The 48 GB GDDR6 memory with 960.0 GB/s bandwidth provides ample headroom for large batch sizes or high-resolution texture sets. Its ray tracing cores (142) enable hardware-accelerated ray tracing, a feature entirely absent from the PG506-232. For workstation users needing display outputs, the RTX 6000 Ada’s 4x DisplayPort 1.4a is essential, while the PG506-232 offers none.

The PG506-232 wins in scenarios where power efficiency and system integration are paramount. Its 165 W TDP allows for denser server deployments with lower cooling requirements, and its 8-pin EPS connector is a standard server power interface, whereas the RTX 6000 Ada requires a 16-pin connector. The PG506-232’s HBM2 memory, while lower in capacity, still delivers 933.1 GB/s bandwidth, which is competitive for memory-bound workloads. Its 99th percentile ranking means it outperforms the vast majority of GPUs, and its 2.4% lead over the AMD Radeon PRO W7900D shows it holds its own against modern rivals. For headless server installations where raw performance is secondary to power budget and physical constraints, the PG506-232 is the pragmatic pick.
