NVIDIA Quadro RTX 8000 NVLINK

At STH, we have looked at a wide variety of graphics cards that span from entry-level to very high end. At the high-end level, we looked at the NVIDIA Titan RTX and even reviewed two Titan RTX’s in NVLINK. To match the Titan RTX level, we examined a single NVIDIA Quadro RTX 8000, which offered an even up-rated feature set. Today we round out our high-end graphics cards with two NVIDIA Quadro RTX 8000’s in NVLINK. The Quadro RTX 8000 matches many of the Titan RTX specifications. Perhaps the biggest delta is with memory, which gets boosted from 24GB to 48GB with ECC support. In an NVLINK configuration, we now have a massive amount of memory at 96GB total. e7-4850 v4

 

At this time, the Quadro RTX 8000 is the pinnacle of PCIe workstation GPU horsepower offered by NVIDIA, suitable for high-end workstations and servers where we can find 8x Quadro RTX 8000’s installed. NVIDIA’s Quadro line of graphics cards is certified for data center use, while the Titan RTX is not. Data-Center use is a big deal not only for certifications but the cooling design is essential in an environment where 8x GPUs can be installed. With the Quadro RTX series, we find blower type cooling fans used, which perform better in tight installations.

NVIDIA recently announced the New NVIDIA A100 PCIe version but that is focused more on the server market and availability the Quadro RTX 8000 is much better at the time we are writing this.

In content creation workstations, having a considerable amount of installed memory can have a significant impact on workflow were very large video or CAD data files are processed quickly with reduced render times. With deep learning and AI workloads, this means a larger number of batches or batch sizes can be evaluated, resulting in faster training times and larger inferencing networks.

NVIDIA Quadro RTX 8000 Overview

We reviewed a Quadro RTX 8000 in November 2019, which can be found here. For this review, we will double up and test the Quadro RTX 8000’s in NVLINK mode. The primary GPU is the same, and we will show the product pictures here again for completeness.

NVIDIA Quadro RTX 8000 is a dual-slot GPU with a length of 10.5″ long. The outside case is very stylish with shinny chrome covering and bright green band across the middle. It is an impressive looking graphics card, be warned, it will attract fingerprints on the chrome surfaces.

While the Titan RTX includes a backplate which we like, the Quadro RTX 8000 does not.

At the end of the Quadro RTX 8000, we find the video outputs, which are 4x DisplayPort 1.4 and 1x VirtualLink port for VR head-mounted displays.

Power connections located at the end of the Quadro RTX 8000, which should be more comfortable for server mountings. These are 1x 6-Pin and 1x 8-Pin connections.

We will use a Quadro branded SLI Bridge to enable NVLINK on the two RTX 8000’s.
