Visualization real-time ray tracing, AI, compute, engineering simulation, and immersive VR professionals required NVIDIA RTX A6000 that delivers designers and engineers to meet demands from their desktop.

84 second-generation RT Cores,

336 third-generation Tensor Cores, and

10,752 CUDA cores with

48 GB of graphics memory.

Connect two RTX A6000s with NVIDIA NVLink for 96 GB of combined GPU memory. And access the power of your workstation from anywhere with remote access software.

Application Performance

Experience fast, interactive performance—powered by the latest NVIDIA Ampere architecture-based GPU—with ultra-fast, on-board graphics memory technology and optimized software drivers for professional applications.

  1. With 84 RT Cores to accelerate photorealistic ray-traced rendering up to 80% faster than the previous generation. Hardware accelerated Motion BVH (bounding volume hierarchy) improves motion blur rendering performance by up to 7X when compared to previous generation.
  2. With 336 Tensor Cores to accelerate AI workflows, the RTX A6000 provides the power necessary for AI development and training workloads. Incredible inferencing performance, combined with enterprise-class stability and reliability, make RTX A6000-powered desktop workstations ideal for professional AI training and inferencing deployments.
  3. Scale application performance even more with NVIDIA NVLink technology that lets you combine two RTX A6000 cards to double the effective GPU memory and performance in a single workstation chassis to 96 GB.
  4. ISV Support: NVIDIA support of the latest OpenGL, DirectX, Vulkan, and CUDA standards, deep independent software vendor (ISV) developer engagements, and certification with over 100 professional software applications.
  5. NVIDIA-tuned, tested, certified, and maintained containers for the top deep learning frameworks, as well as third-party managed high-performance computing (HPC) containers, NVIDIA HPC visualization containers, and partner applications.
  6. Experience stunning imagery through movie-quality, anti-aliasing techniques, high-dynamic range (HDR) color support, higher refresh rates, and up to 8K screen resolution at 60 Hz from a single cable with the DisplayPort 1.4a standard.
  7. Remotely monitor and manage NVIDIA professional products in your enterprise by integrating the NVIDIA Enterprise Management Toolkit (NVWMI) in your IT asset management framework.
  8. Scale up NVIDIA RTX Enterprise driver deployment to hundreds of workstations using NVWMI’s powerful driver installer.

RTX 3090 with 24GB of RAM

  1. Nvidia’s GeForce RTX 3090 consumer board based on the same graphics processor features a different GPU configuration containing 10,496 CUDA cores, 328 tensor cores, 82 RT cores, and a 384-bit memory interface for 24GB of GDDR6X memory.
  2. GeForce RTX 3090, it uses slower memory and therefore features 768 GB/s of memory bandwidth, which is 18% lower than the consumer graphics card (936GB/s), so it will not beat the 3090 in gaming. Meanwhile, because the RTX A6000 has 48GB of DRAM onboard, it will perform better in memory-hungry professional workloads.
  3. While all GeForce RTX graphics cards come with Nvidia Studio drivers that support acceleration in some professional applications, they are not designed to run all professional software suites.


  1. In contrast, professional ISV-certified drivers of the Quadro series and Nvidia RTX A6000 make them a better fit for workstations.


  1. The combination of the Nvidia GeForce RTX A6000 drivers, 48GB of GDDR6, a slightly different GPU configuration, Quadro Sync support, enhanced reliability, a different display output configuration, and a blower-type cooler (which is preferable for multi-GPU configurations.


Application Performance

  1. Nvidia RTX A6000 48GB outperformed its predecessor by 46.6% ~ 92.2% in all four rendering. GPU-accelerated rendering applications benefit require enormous onboard memory capacity when it comes to large scenes.
  2. Compared to Redshift 3, V-Ray 5 scales better with the increase of GPU horsepower and onboard memory capacity in GPU-accelerated rendering workloads.
  3. Modern video editing and color correction applications, such as DaVinci Resolve 16.2.8 and Adobe Premiere Pro 14.8, can also accelerate some of the tasks using GPUs.
  4. Adobe After Effects and Adobe Photoshop can take advantage of GPUs. Yet, both programs are CPU bottlenecked in many cases, which means that any decent graphics processor (not necessarily a professional one) is usually enough for both suites.
  5. Creators need more capacity than standard gaming-class graphics cards provide when editing 8K videos or processing other tasks.
  6. Upgraded RT and tensor cores in Ampere GPUs help with playing ray traced games at 1440p and 4K resolution with the RTX 20-series.
  7. Several creative applications now support Nvidia’s OptiX technology, which lets them tap into the specialized capabilities of RT and tensor cores to speed up tasks.
  8. In addition to the raw denoising and ray tracing speed boosts in rendering tasks, the 2nd-gen RT cores inside the RTX 3090 now support hardware acceleration for ray-traced motion blur, and applications can now support Nvidia’s DLSS technology to speed up their real-time visualizations.
  9. The D5 Render tool for architects already supports DLSS.


  • Poor value for pure gamers
  • Very large, potentially limiting multi-GPU deployment
  • 8K gaming hit and miss
  • Only 1 HDMI 2.1 port
  • 12-pin power adapter


Similarility: Professional and Consumer Cards

Nvidia teamed up with Micron to create GDDR6X, the ultra-fast new memory in the RTX 3080 and 3090. It uses advanced “PAM4” signaling technology that can send up to four possible values per cycle, rather than the usual two. That lets GDDR6X move data twice as fast as previous generation.
