Where Each One Wins

The RTX PRO 6000D Blackwell Max-Q wins the only directly comparable benchmark in the database, and it wins by an 88.5 percent margin in the Steel Nomad DX12 test. Beyond that single result, the data also supports a clear use-case split. The RTX PRO 6000D Blackwell Max-Q is suited for workloads that demand ray tracing and tensor core acceleration, as it is equipped with 188 ray tracing cores and 752 tensor cores, features entirely absent from the GTX 1660 SUPER. Its 110.1 TFLOPS of FP32 performance and 110.1 TFLOPS of FP16 performance indicate capacity for compute-heavy professional tasks. Its 96 GB of GDDR7 memory on a 512-bit bus with 1.79 TB/s bandwidth supports large datasets and high-resolution workloads that would immediately exhaust the 6 GB GDDR6 frame buffer of the GTX 1660 SUPER. The RTX PRO 6000D Blackwell Max-Q also supports DirectX 12 Ultimate, a newer API specification than the DirectX 12 (12_1) supported by the GTX 1660 SUPER.

The GTX 1660 SUPER holds advantages in other areas. Its average benchmark score of 12,986 across all recorded tests is higher than the RTX PRO 6000D Blackwell Max-Q's average of 11,088, although that average for the RTX PRO 6000D is based on a single test. The GTX 1660 SUPER also ranks at the 53rd percentile among all GPUs, three points above the RTX PRO 6000D Blackwell Max-Q's 50th percentile. Its nearest rivals in the database are all cards with average scores within 0.9 percent of its own, showing that it competes in a dense, well-populated performance tier. The GTX 1660 SUPER requires less power, with a 125 W TDP compared to 300 W, and a 300 W suggested power supply compared to 700 W. It is also physically shorter at 229 mm versus 267 mm, which may fit in more compact systems. The GTX 1660 SUPER offers a DVI output in addition to HDMI 2.0 and DisplayPort 1.4a, which could matter for legacy display connections. Its transistor density of 23.2M per mm² and 12 nm process are older, but the card remains a functional option for its performance class.

The Verdict

The data supports a clear split decision. For users whose priority is raw 3D rendering performance in the Steel Nomad DX12 workload, the NVIDIA RTX PRO 6000D Blackwell Max-Q is the definitive choice. Its score of 11,088 versus 1,278 represents an 88.5 percent advantage, and its architectural resources, including 188 ray tracing cores, 752 tensor cores, and 110.1 TFLOPS of FP32 throughput, position it for demanding professional and compute-oriented tasks. The 96 GB GDDR7 memory pool with 1.79 TB/s bandwidth further cements its suitability for memory-intensive workflows. The RTX PRO 6000D Blackwell Max-Q also carries DirectX 12 Ultimate support, PCIe 5.0 x16 connectivity, and four DisplayPort 2.1b outputs.

For users whose requirements match the GTX 1660 SUPER's profile, the older card remains a viable option within its measured performance band. Its average benchmark score of 12,986 places it at the 53rd percentile, and its nearest rivals include the RTX 3050 Ti Mobile, RX 580, and Radeon 740M, all within 0.9 percent. The GTX 1660 SUPER consumes 125 W with a 300 W suggested power supply, making it far less demanding on system power delivery. Its 229 mm length and dual-slot profile allow for easier installation in space-constrained cases. Its DVI output provides compatibility with older monitors. The GTX 1660 SUPER, released in 2019 and now end-of-life, should be selected by users who need a modest, lower-power card in a well-established performance tier, not by those seeking the highest possible benchmark scores.

The RTX PRO 6000D Blackwell Max-Q, released in 2025 and active, should be selected by users who need maximum compute resources, extensive memory capacity, and modern API support. The recorded data shows no scenario where the GTX 1660 SUPER outperforms the RTX PRO 6000D Blackwell Max-Q in a direct head-to-head test. The only benchmark where both were measured side by side is a complete mismatch in favor of the newer card. The verdict from the database is unambiguous: the RTX PRO 6000D Blackwell Max-Q dominates in raw performance, while the GTX 1660 SUPER offers a lower-power, more compact alternative in a different performance class.
