NVIDIA GeForce RTX 4090 D vs NVIDIA Quadro RTX 6000 Comparison

Head-to-Head Benchmarks

The benchmark database shows a decisive performance gap between the NVIDIA GeForce RTX 4090 D and the NVIDIA Quadro RTX 6000. Across the two shared tests, the RTX 4090 D wins both, with margins that are nothing short of dramatic. In Geekbench OpenCL, the RTX 4090 D scores 278,621 against the Quadro RTX 6000's 74,179. That is a delta of 275.6%, meaning the newer card delivers nearly quadruple the raw compute throughput in this API. The Vulkan test tells a similar story, albeit with a narrower spread: the RTX 409 D posts 246,941 versus 129,564 for the Quadro, a 90.6% advantage.

Looking at the average benchmark score across all recorded tests, the RTX 4090 D sits at 178,050, while the Quadro RTX 6000 languishes at 101,872. This places the RTX 4090 D in the 98th percentile of all GPUs in the database, while the Quadro RTX 6000 holds the 94th percentile. The gap in aggregate scoring is roughly 74.8%, which aligns with the individual test results. The RTX 4090 D's nearest rivals in the database are the NVIDIA RTX PRO 5000 Blackwell (average score 182,109, just 2.2% ahead), the NVIDIA A100 SXM4 80 GB (183,725, 3.1% ahead), and the NVIDIA RTX 5000 Ada Generation (184,664, 3.6% ahead). In other words, the RTX 4090 D is within striking distance of those higher-tier workstation cards, despite being a consumer-oriented product.

For the Quadro RTX 6000, its nearest rivals paint a different picture. It sits 4.5% ahead of the AMD Radeon RX 7900M (average score 97,487) and 4.9% ahead of the AMD Radeon Pro VII (97,131). However, it trails the AMD Radeon Pro Vega II Duo (106,750) by 4.6% and the AMD Radeon Pro W6600X (107,342) by 5.1%. So while the Quadro RTX 6000 is not at the bottom of the stack, it is clearly outclassed by the RTX 4090 D's modern architecture. The data shows no scenario in these shared tests where the Quadro RTX 6000 takes the lead.

Architecture Differences

The two cards represent entirely different generations of NVIDIA GPU design. The RTX 4090 D is built on the Ada Lovelace architecture, using the AD102 chip, fabricated on a 5 nm process at TSMC. The Quadro RTX 6000 uses the Turing architecture, with the TU102 chip, on a 12 nm process, also from TSMC. This process jump is the single most important architectural distinction. The RTX 4090 D packs 76,300 million transistors into a 609 mm² die, yielding a transistor density of 125.3 million per square millimeter. The Quadro RTX 6000, by contrast, contains 18,600 million transistors on a larger 754 mm² die, for a density of just 24.7 million per square millimeter. That is a 5.1x density advantage for the newer part, which explains how the RTX 4090 D fits vastly more compute hardware into a smaller physical footprint.

The shading engine differences are stark. The RTX 4090 D has 14,592 shading units, 456 texture mapping units, and 176 render output units. The Quadro RTX 6000 has only 4,608 shading units, 288 TMUs, and 96 ROPs. The RTX 4090 D also carries 114 ray tracing cores and 456 tensor cores, versus 72 RT cores and 576 tensor cores on the Quadro. Interestingly, the Quadro has more tensor cores, but the Ada Lovelace tensor cores in the RTX 4090 D are architecturally more advanced, supporting newer precision formats and higher throughput per core. The FP32 compute rate is 73.54 TFLOPS for the RTX 4090 D, versus 16.31 TFLOPS for the Quadro. The FP16 rate is 73.54 TFLOPS (1:1) on the RTX 4090 D, while the Quadro achieves 32.62 TFLOPS (2:1), meaning the Turing card's FP16 performance is halved relative to its FP32 rate, whereas Ada Lovelace offers a full 1:1 ratio.

Memory architecture also diverges. Both cards have 24 GB of VRAM, but the RTX 4090 D uses GDDR6X on a 384-bit bus, delivering 1.01 TB/s of bandwidth. The Quadro RTX 6000 uses GDDR6 on the same 384-bit bus, but only reaches 672.0 GB/s. Clock speeds tell the rest of the story: the RTX 4090 D runs at a base of 2280 MHz and boosts to 2520 MHz, while the Quadro RTX 6000 sits at 1440 MHz base and 1770 MHz boost. The memory clock is 1313 MHz (21 Gbps effective) on the newer card versus 1750 MHz (14 Gbps effective) on the older one. Pixel rate is 443.5 GPixel/s versus 169.9 GPixel/s, and texture rate is 1,149.1 GTexel/s versus 509.8 GTexel/s.

The Verdict

The data is unambiguous. The RTX 4090 D outperforms the Quadro RTX 6000 in every recorded benchmark, with deltas ranging from 90.6% to 275.6%. For anyone prioritizing raw compute, ray tracing, or rasterization throughput, the RTX 4090 D is the clear choice. Its 98th percentile ranking versus the Quadro's 94th percentile confirms that it sits in a higher performance tier overall. The only reason to consider the Quadro RTX 6000 would be if specific workstation features or software certifications matter, but the benchmark data itself does not support that choice on performance grounds.

The Quadro RTX 6000 does retain one advantage: it is a dual-slot card with a 260 W TDP, versus the RTX 4090 D's triple-slot 425 W design. It also uses more conventional power connectors (1x 6-pin + 1x 8-pin) and has a lower suggested PSU rating of 600 W versus 800 W. For constrained systems, the Quadro may be easier to integrate. However, the performance deficit is so large that the RTX 4090 D is the only sensible pick from a pure benchmark perspective.
