AMD Radeon RX 550X vs NVIDIA Quadro 6000 Comparison

AMD Radeon RX 550X and NVIDIA Quadro 6000 are both end-of-life graphics cards, but they target entirely different workloads and come from different eras of GPU design. The RX 550X is a modern, low-power Polaris part from 2018, while the Quadro 6000 is a 2010-era Fermi professional card with a legacy workstation pedigree. Benchmark data shows the Quadro 6000 edges out the RX 550X in the only shared test, but the overall picture is far more nuanced when you factor in architecture, memory, and feature support.

Where Each One Wins

The NVIDIA Quadro 6000 wins the only direct head-to-head benchmark available, posting a Geekbench OpenCL score of 9846 compared to the RX 550X’s 9662. That is a slim 1.9% margin, but it places the Quadro 6000 at the 47th percentile of all GPUs, while the RX 550X sits at the 49th percentile. Despite being older, the Quadro’s larger memory bus and higher bandwidth give it a slight edge in raw compute throughput in this specific test.

The AMD Radeon RX 550X wins in every other practical category that matters for modern usage. It has a much higher average benchmark score of 10481 versus the Quadro’s 9846, placing it among rivals like the AMD Radeon RX 6500M (10362) and NVIDIA Tesla C2075 (10400). The RX 550X also supports Vulkan 1.3 and DirectX 12 (12_0), while the Quadro 6000 has no Vulkan support and only DirectX 12 (11_0). For any modern game or compute application leveraging those APIs, the RX 550X is the only viable option.

The RX 550X also wins decisively on efficiency and physical footprint. Its 50 W TDP and 250 W suggested PSU requirement contrast sharply with the Quadro 6000’s 204 W TDP and 550 W suggested PSU. The RX 550X draws no auxiliary power connectors and measures 145 mm, while the Quadro 6000 requires both a 6-pin and 8-pin connector and stretches to 248 mm in length. For compact or low-power builds, the RX 550X is the clear choice.

FAQ

A: The Quadro 6000 scores 9846, which is 0.7% above the GeForce GTX 1070’s average score of 9780. It also sits 0.1% above the Quadro M2000M and 0.4% above the AMD FirePro W5000.

Head-to-Head Benchmarks

The sole direct comparison is the Geekbench OpenCL test, where the NVIDIA Quadro 6000 wins with a score of 9846 against the RX 550X’s 9662. That is a 1.9% advantage for the Quadro. While this is the only shared test in the data, it is importantly the RX 550X’s average benchmark score across all tests (10481) is actually higher than the Quadro’s single OpenCL result (9846). This suggests that the RX 550X performs better in other workloads, even though it loses this specific OpenCL test.

The RX 550X’s average score of 10481 places it 1.2% above the AMD Radeon RX 6500M and 0.8% above the NVIDIA Tesla C2075. It also sits 1% above the AMD Radeon R9 M275X and 1.4% above the AMD Radeon RX 6600S. The Quadro 6000’s average of 9846, meanwhile, is nearly identical to the Quadro M2000M (9832, 0.1% delta) and the FirePro W5000 (9803, 0.4% delta), but 1.1% below the GeForce GTX 870M (9959).

Looking at raw compute specifications, the RX 550X delivers 1,211.4 GFLOPS of FP32 performance, which is roughly 17.9% higher than the Quadro 6000’s 1,027.7 GFLOPS. The RX 550X also has higher pixel rate (18.93 GPixel/s vs 16.07 GPixel/s) and texture rate (37.86 GTexel/s vs 32.14 GTexel/s). Yet the Quadro still wins the OpenCL test, likely due to its 384-bit memory bus and 143.4 GB/s bandwidth, which reduces memory bottlenecks in compute workloads.

Specification Differences

The most glaring difference is process node and physical design. The RX 550X uses a 14 nm process at GlobalFoundries, packing 2,200 million transistors into a 103 mm² die. The Quadro 6000 uses a 40 nm process at TSMC, with 3,100 million transistors on a massive 529 mm² die. This explains the transistor density gap: 21.4M per mm² for the RX 550X versus 5.9M per mm² for the Quadro.

Memory configurations also diverge sharply. The Quadro 6000 offers 6 GB of GDDR5 on a 384-bit bus with 143.4 GB/s bandwidth, while the RX 550X has 4 GB of GDDR5 on a 128-bit bus with 96.00 GB/s bandwidth. Memory clock speeds differ too: the Quadro runs at 747 MHz (3 Gbps effective), while the RX 550X runs at 1500 MHz (6 Gbps effective). The RX 550X compensates for its narrower bus with a faster clock.

Core counts and output capabilities are distinct as well. The RX 550X has 512 shading units, 32 TMUs, and 16 ROPs. The Quadro 6000 has 448 shading units, 56 TMUs, and 48 ROPs. The Quadro has more TMUs and ROPs but fewer shading units. Display outputs differ: the RX 550X offers 1x DVI, 1x HDMI 2.0b, and 1x DisplayPort 1.4a, while the Quadro has 1x DVI, 2x DisplayPort, and 1x S-Video. The RX 550X uses a PCIe 3.0 x8 interface, while the Quadro uses PCIe 2.0 x16.

Architecture Differences

The AMD Radeon RX 550X is built on the GCN 4.0 architecture, part of the Polaris (RX 500X) generation. It uses the Lexa chip and supports modern APIs including DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. Its FP16 performance matches FP32 at 1,211.4 GFLOPS (1:1 ratio), indicating a unified shader design without dedicated tensor or ray tracing cores.

The NVIDIA Quadro 6000 is based on the Fermi architecture, specifically the GF100 chip, from the Quadro Fermi (x000) generation. It supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan support and no FP16 capability listed. The Fermi architecture is significantly older, lacking the compute and API features that modern software expects.

The process node difference is stark: 14 nm for the RX 550X versus 40 nm for the Quadro 6000. This accounts for the RX 550X’s vastly higher transistor density (21.4M vs 5.9M per mm²) and much lower power draw (50 W vs 204 W). The RX 550X is also a successor to Polaris and predecessor to Vega, while the Quadro 6000 succeeds Quadro FX Tesla and precedes Quadro Kepler. These architectural generational leaps explain why the RX 550X can achieve higher raw FP32 throughput with far fewer resources.

The Verdict

For modern compute or gaming workloads, the AMD Radeon RX 550X is the clear pick. It supports Vulkan 1.3 and DirectX 12 (12_0), delivers 1,211.4 GFLOPS FP32, and has a higher average benchmark score of 10481. Its 50 W TDP and 250 W PSU requirement make it suitable for systems where the Quadro 6000’s 204 W draw and 550 W PSU would be prohibitive. The RX 550X also offers faster memory clocks (1500 MHz vs 747 MHz) and a more recent 14 nm process.

For legacy workstation compute with large memory demands, the NVIDIA Quadro 6000 has merits. Its 6 GB memory capacity and 384-bit bus with 143.4 GB/s bandwidth are superior to the RX 550X’s 4 GB and 96.00 GB/s. It also wins the only direct OpenCL benchmark (9846 vs 9662), and its 47th percentile ranking sits just below the RX 550X’s 49th. The Quadro’s 448 shading units, 56 TMUs, and 48 ROPs provide strong rasterization throughput for its era, and its 1,027.7 GFLOPS FP32 is still respectable.

The data ultimately favors the RX 550X for any user who values API support, efficiency, and overall benchmark performance. The Quadro 6000 remains relevant only for specific compute tasks that leverage its larger memory bus and capacity, or for systems that cannot use a modern card due to software lock-in. With the RX 550X being end-of-life and the Quadro 6000 even older, neither is a future-proof investment, but the RX 550X is the more capable and practical choice in almost every scenario.
