Compare every NVIDIA Professional GPU
Explore every current GPU across the Ampere, Ada and Blackwell generations, from entry-level low-profile models through to flagship cards. In addition, the Blackwell flagship is available in three cooling variants—Workstation, Max-Q and Server—all featuring the same underlying GPU architecture but optimised for different deployment environments.

How different workloads use your GPU
Rendering performance comparison
Blender GPU rendering provides one of the clearest ways to compare performance across GPU generations. At the flagship level, three generations of architectural improvements deliver up to three times the rendering performance. Likewise, at the mid-range, Blackwell provides around a 40% improvement over Ada while maintaining the same power envelope and form factor.
AI Performance across GPU generations
For local AI inference, performance depends on three key factors: the model must first fit into VRAM, memory bandwidth determines how quickly data can be processed, and Tensor core throughput sets the theoretical performance ceiling. As a result, Blackwell delivers improvements across each of these areas, making it well suited to modern AI workloads.
Video encoding comparison: Ampere vs Ada vs Blackwell
| Capability | Ampere | Ada Lovelace | Blackwell |
| NVENC generation | 7th gen | 8th gen | 9th gen |
| NVDEC generation | 5th gen | 5th gen | 6th gen |
| AV1 encode | No | Yes | Yes – UHQ |
| 4:2:2 10-bit hardware decode | No | No | No |
| NVENC engines, flagship | 1x | 2x | 3x |
For multi-channel ingest, playout, and transcode, the relevant silicon is NVENC and NVDEC — not CUDA cores. Engine count sets the channel ceiling. Format support determines whether the pipeline runs in hardware or falls back to CPU.
4:2:2 10-bit is the chroma format broadcast cameras, ProRes, and most professional codecs record in. On Ampere and Ada that decode work falls to the CPU — on Blackwell it runs in dedicated silicon. AV1 encode roughly halves the bitrate of H.264 at equivalent quality, which matters as soon as streams leave the building. Three NVENC engines on the PRO 6000 Blackwell lets one card replace what previously needed a row of transcode hardware.
Which Blackwell GPU should you upgrade to?
Because each new GPU generation pushes performance further up the product stack, replacing an Ampere card with its direct successor often results in more performance than many users actually need. Instead, the best Blackwell upgrade is frequently one tier below the equivalent Ampere model, delivering similar or greater performance while improving efficiency, memory bandwidth and overall value.
| RTX A6000 Ampere flagship – 300 W – 48GB – 768 GB/s – Dual-slot If you only need to match performance and stay within 300 W, step down one tier. | →RTX PRO 5000 Blackwell Upper-mid – 300 W – 48 GB – 1,344 GB/s – Dual-slot Same slot, same power, more cores and +75% bandwidth. Step up to the PRO 6000 only if 96 GB VRAM or maximum render throughput is required. |

RTX PRO 6000 Blackwell: Workstation vs Max-Q vs Server
The three RTX PRO 6000 Blackwell editions — Workstation, Max-Q, and Server — run identical silicon: 24,064 CUDA cores, 96 GB GDDR7, 1,792 GB/s. They differ only in power envelope and cooling.
The Max-Q caps at 300 W — half the Workstation Edition — and gives up approximately 10–12% in mixed creative workloads. That is close to 1.8× the performance-per-watt. For builds running two to four GPUs on a single PSU, the Max-Q is the variant that makes the density possible. The Server Edition is passively cooled and depends on chassis airflow for rack deployment.
