Whereas AMD’s pitch for its recent workstation GPUs has been very much value for money, Nvidia has focused more on absolute performance – and premium price points.Īccordingly, the three new cards slot in at the top end of its Quadro line-up, with the RTX 5000 and RTX 6000 essentially superseding the older P5000 and P6000.Īs you can see from the table below, each has roughly the same price point as its predecessor, but more CUDA cores, with an attendant increase in single-precision floating-point compute performance. The new Quadro RTX 5000, 60: powerful cards for artists with deep pockets If you want the fine detail, Anandtech has a thorough analysis of the Turing architecture. Other changes in the Turing cards include the introduction of GDDR6 memory, which provides a moderate increase in data transfer rates over the GDDR5X memory used in the higher-end Pascal GPUs. Switching from GDDR5 and GDDR5X memory to the new GDDR6 While that’s less than Nvidia’s ballpark figure of 25x, it’s still a pretty respectable 8x performance boost.Ĭhaos Group has also posted a tech demo of Project Lavina, its work-in-progress real time ray tracing technology, rendering a 300-billion-triangle scene at 25fps on a single Quadro RTX 6000. In most cases, that currently just seems to mean ‘the software will run on Turing GPUs’, but there is one hard figure in the list: Otoy reports that the path tracing kernel in its upcoming OctaneRender 2019.x runs at 3.2 GigaRays/s on the new Quadro RTX 6000 compared to 0.4 GigaRays/s on the existing Quadro P6000. In its launch announcement, Nvidia claims that over two dozen key software firms are supporting Turing. So how much faster will that actually make DCC software? Turing also supports hybrid rendering – a mixture of ray tracing and rasterisation, intended to further accelerate complex jobs – with Nvidia claiming a 6x rasterisation speed boost over Pascal. Nvidia claims that the Turing architecture accelerates ray tracing operations by 25x over the earlier Pascal architecture still used in most of its current Quadro cards. The Turing cards are the first commercial outing for RTX, Nvidia’s hardware acceleration technology for the new DirectX Raytracing capabilities within DirectX 12.Įach features a set of RT cores – new dedicated ray tracing processors – alongside the two core types in Nvidia’s current-gen Volta architecture: CUDA, for general GPU compute, and Tensor, for AI inferencing. Nvidia’s new Turing architecture: new dedicated ‘RT cores’ to accelerate ray tracing The cards – the first to be based on Nvidia’s new Turing architecture, and billed as “the world’s first ray tracing GPUs” – were announced at Siggraph 2018. Nvidia has announced three new additions to its Quadro range of professional workstation graphics cards: the Quadro RTX 5000, Quadro RTX 6000 and Quadro RTX 8000.
