One of the core values of Puget Systems is transparencyWe detest hype in the midst of an industry that is full of it. Our mission is to provide the highest quality hardware and consultation services to our customers, and to back up our decisions by freely sharing what we've learned along the way. To earn a place in our product line, a computer component undergoes rigorous testing. We apply the results of our testing, along with our years of experience in learning reliability trends and manufacturer characteristics, to make prudent decisions about what we can put our name behind, whether that's an individual part or an entire computer. With the following articles, we are writing up the results of these internal processes and discussions, and taking them public. We feel we can take this on with a unique perspective as we evaluate each topic with the experience, resources, and objectivity of a system builder. If there is a topic you'd like us to write about, email us at !
GPU based renderers like OctaneRender and Redshift make use of the video cards in a computer to process ray tracing and other calculations in order to create photo-realistic images and videos. The performance of an individual video card, or GPU, is known to impact rendering speed - as is the number of video cards installed in a single computer. But what about the connection between each video card and the rest of the system? This interconnect is called PCI Express and comes in a variety of speeds. In this article, we will look at how benchmarks for these programs perform across PCI-E 3.0 and 2.0 with x1, x4, x8, and x16 lanes.
We found previously that stacking multiple RTX 2080 video cards next to each other for multi-GPU rendering led to overheating and significant performance throttling, due to the dual-fan cooler NVIDIA has adopted as the standard on this generation of Founders Edition cards. Now that manufacturers like Asus are putting out single-fan, blower-style cards we can repeat our testing to see if the throttling issues are resolved and find out how well these video cards scale when using 1, 2, 3, or even 4 of them for GPU-based rendering in OctaneRender and Redshift.
OctaneRender is a GPU-based rendering engine, and as of version 3.08 is compatible with NVIDIA's Turing graphics architecture in the GeForce RTX 2080 and 2080 Ti cards. Let's take a look at how these new GeForce models compare to the previous generation.
The new GeForce RTX series cards perform well in GPU based rendering, as individual cards, and have great potential for the future thanks to their new RT cores. However, when stacking them together to measure multi-GPU scaling we ran into some serious problems.
GPU rendering engines like OctaneRender and Redshift utilize the computational power of the graphics processing chips on video cards to create photo-realistic images and animations. The more powerful the video card, the faster the rendering process goes - and multiple video cards can be used together to further improve performance. But can those video cards be a mix of different models, or do they all need to be identical?
Now that OctaneRender has been updated to support the Volta GPU architecture, how well does its performance scale when using multiple Titan Vs? And how does that compare to other popular rendering cards like the GeForce GTX 1080 Ti?
OctaneRender is a GPU-based rendering engine, so the bulk of the processing it does is carried out on the video cards in a system. Different processors and motherboards can impact the number of cards that can fit in a single system, but do they matter beyond that? Does the CPU itself have any impact on rendering speed/performance?
Benchmark results demonstrating that PCI-Express x8 vs x16 speeds don't impact GPU rendering performance.
This article looks at several motherboard chipsets, including X299 and X399, comparing how well they handle performance scaling across multiple GPUs in OctaneBench 3.06.2.
