NVIDIA Quadro RTX 6000 vs NVIDIA RTX 4000 SFF Ada Generation Comparison

The NVIDIA RTX 4000 SFF Ada Generation and the NVIDIA Quadro RTX 6000 represent two distinct eras of professional graphics. The data shows a clear split: the RTX 4000 SFF Ada dominates in OpenCL compute workloads, while the Quadro RTX 6000 holds a significant edge in Vulkan performance. The RTX 4000 SFF Ada is the modern choice for compute-heavy tasks requiring high efficiency, whereas the Quadro RTX 6000 remains competitive for specific API workloads and offers larger memory capacity, though it is end-of-life and power-hungry.

The Verdict

The benchmark results dictate a clear separation of use cases. If your primary applications rely on OpenCL, the NVIDIA RTX 4000 SFF Ada Generation is the unequivocal winner. Its OpenCL score of 124,812 is a staggering 68.3% higher than the Quadro RTX 6000's 74,179. This is the card for compute-centric tasks like rendering, simulation, or data processing that leverage OpenCL.

Conversely, if your software stack is built around Vulkan, the NVIDIA Quadro RTX 6000 is the better performer. Its Vulkan score of 129,564 exceeds the RTX 4000 SFF Ada's 109,364 by 15.6%. This makes it the stronger choice for Vulkan-based game engines, real-time visualization, or other workloads that heavily utilize this API.

The overall average benchmark scores also favor the RTX 4000 SFF Ada. It posts an average score of 117,088, placing it in the 95th percentile of all GPUs, while the Quadro RTX 6000 averages 101,872, sitting in the 94th percentile. This suggests the RTX 4000 SFF Ada is generally the more capable card across mixed workloads. However, the Quadro RTX 6000's 24 GB of memory versus the RTX 4000 SFF Ada's 20 GB makes it the better option for datasets that push beyond 20 GB, even if compute performance is lower. Choose the RTX 4000 SFF Ada for raw compute efficiency and modern architecture; choose the Quadro RTX 6000 for Vulkan-specific performance and larger memory capacity.

Architecture Differences

The two cards are built on fundamentally different architectures. The RTX 4000 SFF Ada uses the Ada Lovelace architecture on a 5 nm process from TSMC, housing the AD104 chip with 35,800 million transistors on a 294 mm² die. This results in a transistor density of 121.8M per mm². In contrast, the Quadro RTX 6000 uses the older Turing architecture on a 12 nm process, featuring the TU102 chip with 18,600 million transistors on a much larger 754 mm² die, yielding a transistor density of only 24.7M per mm².

These architectural differences lead to divergent core configurations. The RTX 4000 SFF Ada has 6,144 shading units, 48 RT cores, and 192 tensor cores. The Quadro RTX 6000 has fewer shading units at 4,608 but more RT cores at 72 and a significantly higher count of 576 tensor cores. Memory configurations also differ: the RTX 4000 SFF Ada uses 20 GB of GDDR6 on a 160-bit bus with 280.0 GB/s bandwidth, while the Quadro RTX 6000 uses 24 GB of GDDR6 on a 384-bit bus with 672.0 GB/s bandwidth. The newer card's FP32 compute is higher at 19.17 TFLOPS versus 16.31 TFLOPS, but the Quadro's FP16 performance is higher at 32.62 TFLOPS (2:1) compared to the RTX 4000 SFF Ada's 19.17 TFLOPS (1:1).

Power and physical requirements are drastically different. The RTX 4000 SFF Ada has a 70 W TDP, requires no power connectors, and needs only a 250 W suggested PSU. It also uses a PCIe 4.0 x16 interface. The Quadro RTX 6000, on the other hand, has a 260 W TDP, requires 1x 6-pin and 1x 8-pin power connectors, needs a 600 W suggested PSU, and uses the older PCIe 3.0 x16 interface. The RTX 4000 SFF Ada is also much smaller at 168 mm in length, compared to the Quadro's 267 mm.

Where Each One Wins

The benchmark wins are split exactly one-to-one, but the magnitude of those wins tells the story. The RTX 4000 SFF Ada's OpenCL victory is monumental. A 68.3% lead over the Quadro RTX 6000 is not a marginal improvement; it is a generational leap in compute throughput. This makes the RTX 4000 SFF Ada the clear winner for scientific computing, AI inference, video encoding, and any professional application that relies heavily on OpenCL compute shaders.

The Quadro RTX 6000's Vulkan win is also substantial, with a 15.6% lead. This indicates that while the Turing architecture is older, its Vulkan driver implementation and hardware design are still highly effective. This card is the better choice for real-time rendering in Vulkan-based engines, such as those used in some architectural visualization or game development tools. Its 24 GB memory buffer also provides a headroom advantage for massive textures or complex 3D scenes that might not fit in the RTX 4000 SFF Ada's 20 GB.

Beyond raw benchmark scores, the RTX 4000 SFF Ada's efficiency is a massive practical win. Its 70 W TDP and lack of power connectors mean it can be installed in systems with modest power supplies and in space-constrained or thermally-limited chassis. The Quadro RTX 6000's 260 W TDP and 600 W PSU requirement demand a more robust system, limiting its deployment flexibility.

The results suggest that a user's choice of API is the single most critical factor in deciding between these two cards.

Specification Differences

The specification sheets for these two cards reveal a complete generational overhaul. The most obvious difference is in the process node: the RTX 4000 SFF Ada uses a 5 nm process, while the Quadro RTX 6000 uses a 12 nm process. This drives the massive difference in transistor density (121.8M / mm² vs 24.7M / mm²) and die size (294 mm² vs 754 mm²). The chip design also differs, with the RTX 4000 SFF Ada using the AD104 and the Quadro RTX 6000 using the TU102.

Core counts and memory specs are also starkly different. The RTX 4000 SFF Ada has 6,144 shading units, 192 TMUs, and 64 ROPs, while the Quadro RTX 6000 has 4,608 shading units, 288 TMUs, and 96 ROPs. The RTX 4000 SFF Ada has 48 RT cores and 192 tensor cores, while the Quadro RTX 6000 has 72 RT cores and 576 tensor cores. Memory size is 20 GB vs 24 GB, with bus widths of 160-bit vs 384-bit, leading to bandwidths of 280.0 GB/s vs 672.0 GB/s. The base and boost clocks are also lower on the RTX 4000 SFF Ada (720 MHz / 1560 MHz) compared to the Quadro RTX 6000 (1440 MHz / 1770 MHz), yet the newer card still achieves higher FP32 throughput.

Power and physical specifications could not be more different. The RTX 4000 SFF Ada is a 70 W card with no power connectors and a 250 W suggested PSU, while the Quadro RTX 6000 is a 260 W card needing 1x 6-pin and 1x 8-pin connectors and a 600 W PSU. The RTX 4000 SFF Ada is a compact 168 mm card with 4x mini-DisplayPort 1.4a outputs, while the Quadro RTX 6000 is a longer 267 mm card with 4x DisplayPort 1.4a and 1x USB Type-C. Finally, the bus interface differs, with the RTX 4000 SFF Ada using PCIe 4.0 x16 and the Quadro RTX 6000 using PCIe 3.0 x16. The Quadro RTX 6000 has a launch MSRP of 6,299 USD.
