NVIDIA GB10 vs NVIDIA PG506-232 Comparison

Head-to-Head Benchmarks

The database records one direct comparison between the NVIDIA PG506-232 and the NVIDIA GB10: the Geekbench OpenCL test. In this workload, the PG506-232 scores 225,124, while the GB10 scores 120,137. The PG506-232 wins by a delta of 87.4%, a substantial margin that places the two accelerators in different performance tiers for OpenCL compute.

Contextualizing the PG506-232's result, its average benchmark score of 225,124 puts it in the 99th percentile of all GPUs in the database. Its nearest rivals include the AMD Radeon PRO W7900D at 219,827, which the PG506-232 outperforms by 2.4%. The NVIDIA A100 PCIe 80 GB trails at 207,124, a delta of 8.7% in favor of the PG506-232. Against the NVIDIA RTX 6000D, the PG506-232 leads by 14.9%, with that card scoring 195,964. The only listed rival ahead of the PG506-232 is the NVIDIA L20, which reaches 251,147, a 10.4% advantage over the PG506-232. These figures indicate that the PG506-232 sits comfortably among high-end server compute accelerators, just below the top of the measured range.

The GB10, by contrast, records an average benchmark score of 117,393, placing it in the 95th percentile of all GPUs. Its nearest rival is the NVIDIA RTX 4000 SFF Ada Generation at 117,088, a difference of only 0.3% in favor of the GB10. The AMD Radeon PRO W7700 scores 118,976, which is 1.3% ahead of the GB10. The NVIDIA Tesla V100 SXM2 16 GB trails at 114,395, a 2.6% gap, and the NVIDIA RTX A5500 Mobile scores 113,944, 3.0% behind. The GB10's score cluster is tight, with all four rivals within roughly 3 percentage points, suggesting that the GB10's compute performance in this test is closely matched with mid-range workstation and mobile accelerators.

The head-to-head result is decisive for OpenCL: the PG506-232 delivers nearly double the raw score of the GB10. However, the GB10 also has a Vulkan result in the database, scoring 114,648, which is slightly lower than its OpenCL score of 120,137. No Vulkan result is recorded for the PG506-232, so the comparison between the two in that API cannot be drawn from the available data.

When interpreting the 87.4% delta, it is important to note that the PG506-232 is an end-of-life server part with a 165 W thermal design power, while the GB10 is an active integrated graphics processor with a 140 W TDP. The performance gap in OpenCL aligns with the architectural and specification differences between the two, which are detailed in the sections below. The data does not suggest the GB10 is intended to compete with the PG506-232 in raw compute throughput; rather, the two occupy different segments of the accelerator market.

The Verdict

The recorded data points to a clear split in intended roles. For applications that prioritize OpenCL compute throughput, the NVIDIA PG506-232 is the stronger choice. Its 225,124 OpenCL score is 87.4% higher than the GB10's 120,137, and its 99th percentile rank among all GPUs places it above the overwhelming majority of measured hardware. The PG506-232 also leads several established server accelerators, including the NVIDIA A100 PCIe 80 GB by 8.7% and the NVIDIA RTX 6000D by 14.9% in average score. Users whose workloads depend on sustained compute performance in this benchmark should favor the PG506-232.

The NVIDIA GB10, however, offers a different set of characteristics that may be more relevant to other use cases. Its average benchmark score of 117,393 places it in the 95th percentile, which is still high overall, but its closest rivals are mid-range workstation and mobile parts. The GB10 trails the AMD Radeon PRO W7700 by 1.3% and leads the NVIDIA RTX 4000 SFF Ada Generation by only 0.3%. This suggests the GB10 is competitive with the middle tier of workstation accelerators, not with the high-end server segment occupied by the PG506-232.

The GB10 also holds advantages in areas outside raw compute benchmarks. It has a 128 GB memory capacity compared to the PG506-232's 24 GB, and it uses LPDDR5X memory rather than HBM2. The GB10 includes 48 ray tracing cores, while the PG506-232 has none recorded. The GB10 is an active, in-production part with a PCIe 5.0 interface, while the PG506-232 is end-of-life and limited to PCIe 4.0. The GB10 also has a display output, a single HDMI port, whereas the PG506-232 has no display outputs. These factors make the GB10 a more flexible, current-generation product for systems that need graphics output or larger memory pools.

The decision rests on workload requirements. If the primary metric is OpenCL compute performance, the PG506-232 is the clear winner in this comparison. If the system needs current-generation features, a larger memory footprint, ray tracing support, and a lower thermal envelope, the GB10 is the appropriate selection. The data does not support a single universal recommendation; it supports matching the hardware to the task.

Architecture Differences

The NVIDIA PG506-232 is built on the GA100 chip using the Ampere architecture, fabricated on a 7 nm process at TSMC. It belongs to the Server Ampere generation. The GB10 uses the GB20B chip with the Blackwell 2.0 architecture, manufactured on a 5 nm process, also at TSMC, and belongs to the Server Blackwell generation. The shift from 7 nm to 5 nm represents a process node advancement, though the database does not record a transistor count for the GB10, so a direct density comparison is not possible. The PG506-232 contains 54,200 million transistors on a die size of 826 mm², yielding a transistor density of 65.6 million per square millimeter. The GB10's die size is 382 mm², but its transistor count and density are unknown.

The PG506-232's GA100 die is larger than the GB10's GB20B die, but the GB10 compensates with a more advanced process node and higher clock speeds. The PG506-232 has a base clock of 930 MHz and a boost clock of 1440 MHz, while the GB10 runs at a base clock of 1665 MHz and a boost clock of 2418 MHz. The GB10's boost clock is substantially higher, which contributes to its higher FP32 throughput despite a smaller die.

The memory architectures differ fundamentally. The PG506-232 uses 24 GB of HBM2 on a 3072-bit bus, delivering 933.1 GB/s of bandwidth. The GB10 uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The PG506-232's memory bandwidth is roughly 3.4 times higher, while the GB10's capacity is more than five times larger. The GB10's memory clock is recorded at 1067 MHz with 8.5 Gbps effective, while the PG506-232's memory runs at 1215 MHz with 2.4 Gbps effective.

The GB10 has 6144 shading units, 384 TMUs, 48 ROPs, 384 tensor cores, and 48 ray tracing cores. The GB10 has more shading units and tensor cores, but fewer ROPs. The PG506-232 has no ray tracing cores recorded. The PG506-232 achieves a pixel rate of 138.2 GPixel/s and a texture rate of 322.6 GTexel/s. The GB10 records 116.1 GPixel/s and 928.5 GTexel/s. The GB10's texture rate is nearly three times higher, while the PG506-232 holds a modest lead in pixel rate.

The API support also differs. The PG506-232 has no recorded DirectX, OpenGL, or Vulkan support. The GB10 lists DirectX, OpenGL, and Vulkan as N/A. Neither part exposes conventional graphics APIs in the database, but the GB10 does have a Vulkan benchmark score recorded. The PG506-232 has no display outputs, while the GB10 includes one HDMI output.
