NVIDIA GeForce RTX 5080 vs NVIDIA Quadro M6000 Comparison

# NVIDIA GeForce RTX 5080 vs NVIDIA Quadro M6000

The GeForce RTX 5080 and the Quadro M6000 occupy different corners of the GPU landscape, and the benchmark data illustrates a substantial generational and market-segment gap. The RTX 5080 is a current-generation enthusiast card, while the Quadro M6000 is a professional workstation product from the Maxwell era. This comparison uses only recorded database measurements to map where each card stands.

Head-to-Head Benchmarks

The most direct way to measure the performance gap is through the head-to-head benchmark results. The database records a 494.4% win for the GeForce RTX 5080 in the geekbench_opencl test, where it scored 235,901 points against the Quadro M6000's 39,688 points. The second head-to-head test, geekbench_vulkan, shows a similarly large margin: 255,450 points for the RTX 5080 versus 46,913 for the Quadro, a 444.5% advantage for the newer card.

These are not close contests. The RTX 5080 is more than five times faster in these compute-oriented tests. The Quadro M6000 was built for stability and professional certification, not raw throughput, and its age in GPU generations shows. In the average benchmark score across all recorded tests, the RTX 5080 sits at 56,083 points, which is 29.6% higher than the Quadro M6000's 43,301 average. This average is pulled up by the RTX card's strong showing in newer API tests, while the Quadro holds its ground in OpenCL and Vulkan workloads.

Architecture Differences

The architectural gap is a defining feature. The GeForce RTX 5080 is built on the Blackwell 2.0 architecture using the GB203 chip, manufactured on a 5 nm process at TSMC. It integrates 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per square millimeter. The Quadro M6000, by contrast, uses the Maxwell 2.0 architecture with the GM200 die, built on a 28 nm process at TSMC. It packs 8, million transistors on a larger 601 mm die, for a density of 13.3 million per square millimeter.

This is a fundamental generational leap. The RTX 5080 features 10,752 shading units, 336 texture mapping units, and 112 ROPs. It also includes 84 RT cores and 336 tensor cores, enabling AI-assisted features like DLSS. The Quadro M6000 has 3,072 shading units, 192 texture units, and 96 ROPs, but lacks RT cores and tensor cores entirely. The M6000 is a pure rasterization card, built for viewport manipulation and compute in professional applications. The Blackwell card also carries 512 KB of L2 cache (the Quadro has no listed L2 cache size in the data).

The clock speeds tell a similar story. The RTX 5080 runs at a base of 2295 MHz with a boost up to 2617 MHz. The Quadro M6000 is clocked at 988 MHz base and 1114 MHz boost. The memory subsystem also differs greatly: the RTX uses 16 GB of GDDR7 on a 256-bit bus with 960.0 GB/s of bandwidth, while the Quadro uses 12 GB of GDDR5 on a 384-bit bus for 317.4 GB/s.

The rendering limits reflect the architecture. The RTX 5080 reaches 293.1 GPixel/s pixel fill rate and 879.3 GTexel/s texture fill rate. The Quadro M6000 records 106.9 GPixel/s and 213.9 GTexel/s. FP32 compute on the newer card is 56.28 TFLOPS, while the M6000 is rated at 6.844 TFLOPS. The RTX 5080 does not list a separate FP16 figure, instead it is 56.28 TFLOPS (1:1), meaning the card is likely treating FP16 at the same rate as FP32. The M6000 has no FP16 in the database.

Power and cooling requirements scale with the performance. The RTX 5080 has a 360 W TDP, uses a dual-slot cooler, and requires a 750 W power supply with a 16-pin connector. The Quadro M6000 is also dual-slot, but with a 250 W TDP and a single 8-pin power connector, needing a 600 W PSU. The RTX connects via PCIe 5.0 x16, while the Quadro is a PCIe 3.0 x16 card. Display outputs: the RTX 5080 has 1 HDMI 2.1b and 3 DisplayPort 2.1b outputs; the Quadro has 1 DVI and 4 DisplayPort 1.2 outputs.

FAQ

Where Each One Wins

GeForce RTX 5080 wins in: All recorded benchmark tests, compute (FP32 with 56.28 TFLOPS), and memory bandwidth (960.0 GB/s). It is the newer architecture with AI acceleration features (RT cores, Tensor Cores) and supports the latest APIs (DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4). The card is physically smaller in the data (304 mm length vs 267 mm, though the M6000 is 4.4 inches vs 5.4 inches). It also has more display outputs (1 HDMI + 3 DP vs 1 DVI + 4 DP).

Quadro M6000 wins in: Memory capacity per card (12 GB vs 16 GB, the Quadro has more VRAM in the database). The M6000 is a workstation card with a lower 250 W power draw and a 600 W PSU recommendation, making it easier to place in a professional chassis. It is end-of-life with the software certification for professional ISV (CAD) work, and its 6.844 TFLOPS FP32 is adequate for that segment.

For a buyer choosing for gaming, rendering, or compute, the RTX 5080 is the data-driven choice. For a professional workstation that uses CAD and ISV-certified applications, the Quadro M6000 is the card that has the endurance and the certification.
