NVIDIA RTX 6000D vs NVIDIA Tesla V100 SXM2 32 GB Comparison

NVIDIA’s RTX 6000D and Tesla V100 SXM2 32 GB represent two distinct eras of professional GPU design, and the benchmark data reflects a generational chasm. The RTX 6000D, built on Blackwell 2.0 architecture, delivers a 194.9% higher Geekbench OpenCL score than the Volta-based V100. The V100 SXM2 32 GB, however, remains a competent compute card for legacy workloads, holding a 96th percentile rank among all GPUs. The decision between them is not about raw capability—the RTX 6000D wins that outright—but about compatibility, power constraints, and whether the workload can leverage the newer architecture’s features.

The Verdict

The RTX 6000D is the clear choice for any modern, performance-driven workstation. Its average benchmark score of 195,964 places it in the 98th percentile of all GPUs, and it leads the V100 SXM2 32 GB by a substantial margin in the only shared test. In Geekbench OpenCL, the RTX 6000D scores 388,405 versus the V100’s 131,696—a 194.9% advantage. This is not a close contest; it is a landslide. For any user running current software that supports Blackwell’s feature set, the RTX 6000D is the only sensible pick.

The Tesla V100 SXM2 32 GB is for a very specific niche: those locked into legacy Tesla Volta infrastructure. Its average score of 137,731 and 96th percentile ranking show it is still a capable compute device, but it is end-of-life and lacks any display outputs. If your software stack is tied to CUDA 9.x-era code or you require the SXM2 form factor for an existing server chassis, the V100 remains functional. Otherwise, the data shows no reason to choose it over the RTX 6000D.

For mixed environments, consider the power envelope. The V100 SXM2 32 GB consumes 250 W, while the RTX 6000D draws 600 W. If power delivery is a hard constraint, the V100 is easier to accommodate. But if performance per watt matters, the RTX 6000D’s massive lead in raw compute efficiency—achieving nearly three times the OpenCL score at 2.4 times the power draw—makes it the better investment.

Architecture Differences

The RTX 6000D is built on the GB202 chip using Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. It packs 92,200 million transistors onto a 750 mm² die, yielding a transistor density of 122.9 million per square millimeter. The V100 SXM2 32 GB uses the GV100 chip with Volta architecture, manufactured on a 12 nm process. Its 21,100 million transistors occupy a larger 815 mm² die, with a density of just 25.9 million per square millimeter.

Memory technology separates them completely. The RTX 6000D uses 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The V100 SXM2 32 GB uses 32 GB of HBM2 on a massive 4096-bit bus, but only achieves 898.0 GB/s. The RTX 6000D also has a much higher memory clock at 1560 MHz (25 Gbps effective) versus the V100’s 877 MHz (1754 Mbps effective).

Compute resources differ dramatically. The RTX 6000D has 19,968 shading units, 624 TMUs, and 192 ROPs, with 156 RT cores and 624 tensor cores. The V100 SXM2 32 GB has 5,120 shading units, 320 TMUs, and 128 ROPs, with no RT cores but 640 tensor cores. Clock speeds also favor the newer card: 1992 MHz base and 2430 MHz boost for the RTX 6000D versus 1290 MHz base and 1530 MHz boost for the V100.

The RTX 6000D supports PCIe 5.0 x16, while the V100 SXM2 32 GB is limited to PCIe 3.0 x16. The RTX 6000D offers 4x DisplayPort 2.1b outputs; the V100 has none. API support differs as well: the RTX 6000D supports DirectX 12 Ultimate (12_2), while the V100 peaks at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

The RTX 6000D wins in every measured benchmark category. It has a 194.9% advantage in Geekbench OpenCL, and it holds the only head-to-head win in the dataset. The data also shows it is 4.7% ahead of the NVIDIA A100 SXM4 40 GB and 6.1% ahead of the RTX 5000 Ada Generation in average score, indicating broad superiority over recent professional cards.

The V100 SXM2 32 GB does not win any head-to-head benchmark against the RTX 6000D, but it has strengths in specific contexts. Its nearest rival data shows it is only 0.9% behind the AMD Radeon PRO V620 and 1.4% ahead of the AMD Radeon Pro W6800X Duo, meaning it remains competitive within its own generation. The V100 also wins on power efficiency in absolute terms—250 W versus 600 W—and its SXM2 form factor is designed for dense server deployments where the RTX 6000D’s dual-slot, 304 mm length might not fit.

For ray tracing workloads, the RTX 6000D has a definitive edge with 156 dedicated RT cores; the V100 has none. For pure tensor operations, the V100’s 640 tensor cores are numerically more numerous than the RTX 6000D’s 624, but the newer architecture’s higher clocks and FP16 throughput (97.04 TFLOPS versus 31.33 TFLOPS) suggest the RTX 6000D is faster in practice.

Contextualizing this score, the RTX 6000D’s average benchmark score of 195,964 puts it 4.7% ahead of the A100 SXM4 40 GB and 6.1% ahead of the RTX 5000 Ada Generation. The V100 SXM2 32 GB’s average of 137,731 places it just 0.2% behind the Tesla V100 PCIe 16 GB and 0.9% ahead of the AMD Radeon PRO V620. The RTX 6000D is not merely better than the V100; it outperforms the V100’s entire peer group by a wide margin.

The V100’s best showing in its rival set is against the AMD Radeon Pro W6800X Duo, where it leads by 1.4%. The RTX 6000D’s worst relative performance is against the A100 PCIe 80 GB, where it trails by 5.4%. This suggests the RTX 6000D sits near the top of the professional GPU hierarchy, while the V100 SXM2 32 GB is a mid-pack performer from a prior generation.

Specification Differences

The process node is a major divider: 5 nm for the RTX 6000D versus 12 nm for the V100 SXM2 32 GB. Transistor counts follow suit—92,200 million versus 21,100 million—on die sizes of 750 mm² and 815 mm² respectively. The RTX 6000D’s transistor density of 122.9M per mm² dwarfs the V100’s 25.9M per mm².

Clocks are uniformly higher on the RTX 6000D. Base clock is 1992 MHz versus 1290 MHz; boost clock is 2430 MHz versus 1530 MHz. Memory clock is 1560 MHz (25 Gbps effective) versus 877 MHz (1754 Mbps effective). These clock advantages compound the architectural improvements.

Memory configuration differs fundamentally: 84 GB GDDR7 on a 448-bit bus versus 32 GB HBM2 on a 4096-bit bus. Bandwidth favors the RTX 6000D at 1.40 TB/s versus 898.0 GB/s. Shader resources are also skewed: 19,968 shading units, 624 TMUs, and 192 ROPs for the RTX 6000D; 5,120 shading units, 320 TMUs, and 128 ROPs for the V100.

The RTX 6000D has 156 RT cores; the V100 has none. Tensor core counts are close (624 versus 640), but FP16 performance differs: the RTX 6000D achieves 97.04 TFLOPS at 1:1 ratio, while the V100 manages 31.33 TFLOPS at 2:1 ratio. Pixel rate is 466.6 GPixel/s versus 195.8 GPixel/s, and texture rate is 1,516.3 GTexel/s versus 489.6 GTexel/s.
