NVIDIA RTX 6000 Ada Generation vs NVIDIA RTX 6000D Comparison

The Verdict

The data presents a clear generational split. The NVIDIA RTX 6000 Ada Generation and the NVIDIA RTX 6000D are both top-tier workstation cards, but they serve different points in the product lifecycle. The RTX 6000 Ada is an end-of-life product built on the Ada Lovelace architecture, while the RTX 6000D is an active product built on the newer Blackwell 2.0 architecture. Based strictly on the benchmark results, the RTX 6000D is the faster card in compute workloads, posting a 19.8% higher score in the Geekbench OpenCL test. However, the RTX 6000D’s average benchmark score is significantly lower than its predecessor’s, which complicates a simple "buy the newer one" recommendation. The RTX 6000 Ada’s average score of 287,237 places it in the 99th percentile of all GPUs, while the RTX 6000D’s average score of 195,964 places it in the 98th percentile. This suggests that while the RTX 6000D wins the single head-to-head test, the RTX 6000 Ada may be more consistently performant across a broader range of workloads.

The verdict depends on the specific workload. For users prioritizing raw compute in a single, well-optimized API like OpenCL, the RTX 6000D is the choice, as it delivers 388,405 points versus the RTX 6000 Ada’s 311,629 points. For users needing a more balanced, proven performer with a higher average score across all benchmarks, the RTX 6000 Ada is the safer pick. The RTX 6000D’s lower average score, despite its newer architecture, indicates that its wins may be concentrated in specific tests rather than spread across the board. The RTX 6000D also offers substantially more memory (84 GB versus 48 GB) and a wider memory bus, which matters for large datasets. The RTX 6000 Ada, however, has a much lower TDP (300 W versus 600 W), making it easier to integrate into existing systems.

Architecture Differences

The two cards are built on fundamentally different architectures. The RTX 6000 Ada uses the AD102 chip based on the Ada Lovelace architecture, while the RTX 6000D uses the GB202 chip based on the Blackwell 2.0 architecture. The process node is the same for both — TSMC’s 5 nm process — but the chip designs differ significantly. The RTX 6000 Ada has 76,300 million transistors on a 609 mm² die, resulting in a transistor density of 125.3M per mm². The RTX 6000D has 92,200 million transistors on a larger 750 mm² die, with a slightly lower transistor density of 122.9M per mm².

The memory subsystems are also distinct. The RTX 6000 Ada uses 48 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The RTX 6000D uses 84 GB of GDDR7 memory on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The newer GDDR7 standard and wider bus give the RTX 6000D a clear advantage in memory-intensive tasks. The clock speeds also differ: the RTX 6000 Ada has a base clock of 915 MHz and a boost clock of 2505 MHz, while the RTX 6000D runs at a much higher base clock of 1992 MHz and a boost clock of 2430 MHz. The RTX 6000D’s higher base clock suggests better sustained performance under load.

Core counts are higher on the RTX 6000D across the board. It has 19,968 shading units versus 18,176, 624 texture mapping units versus 568, and 624 tensor cores versus 568. The RTX 6000D also has more ray tracing cores: 156 versus 142. The RTX 6000 Ada has a slightly higher pixel rate at 481.0 GPixel/s compared to 466.6 GPixel/s, but the RTX 6000D has a higher texture rate at 1,516.3 GTexel/s versus 1,422.8 GTexel/s. The FP32 and FP16 performance figures are both 91.06 TFLOPS for the RTX 6000 Ada, while the RTX 6000D achieves 97.04 TFLOPS in both. The RTX 6000D also uses PCIe 5.0 x16, while the RTX 6000 Ada uses PCIe 4.0 x16, and the RTX 6000D features DisplayPort 2.1b outputs versus DisplayPort 1.4a on the Ada card.

Head-to-Head Benchmarks

The only direct head-to-head benchmark available is Geekbench OpenCL, and the RTX 6000D wins decisively. The RTX 6000D scores 388,405 points, while the RTX 6000 Ada scores 311,629 points. This is a 19.8% difference in favor of the RTX 6000D. This is a substantial margin, indicating that the Blackwell architecture’s higher core count and faster memory provide a significant advantage in OpenCL compute workloads.

However, the average benchmark scores tell a different story. The RTX 6000 Ada has an average benchmark score of 287,237, which is 46.6% higher than the RTX 6000D’s average score of 195,964. This discrepancy is critical. The RTX 6000D’s single OpenCL win is impressive, but its overall average is dragged down by other tests. The RTX 6000 Ada’s nearest rivals include the NVIDIA L40S (295,763, 2.9% higher) and the AMD Instinct MI300X (317,994, 9.7% higher), while it leads the NVIDIA L40 (284,111, 1.1% higher) and the NVIDIA L20 (251,147, 14.4% higher). The RTX 6000D’s nearest rivals are older data center parts: it leads the NVIDIA Tesla V100S PCIe 32 GB (194,415, 0.8% higher) and the NVIDIA A100 SXM4 40 GB (187,147, 4.7% higher), but trails the NVIDIA A100 PCIe 80 GB (207,124, 5.4% lower) and the NVIDIA RTX 5000 Ada Generation (184,664, 6.1% higher).

The RTX 6000D also has a 3DMark Steel Nomad DX12 score of 3,522, which is not available for the RTX 6000 Ada, so no direct comparison can be made there. The RTX 6000 Ada has a Geekbench Vulkan score of 262,845, which is not available for the RTX 6000D. The data shows that the RTX 6000D is the clear winner in the one test where both are measured, but the RTX 6000 Ada’s superior average score suggests it is more consistent across a wider range of applications.
