NVIDIA Lite Hash Rate GPU Performance

Written on October 26, 2021 by William George

In an attempt to make their GeForce line of consumer video cards less appealing to crypto miners, NVIDIA has updated many of their GPUs with "lite hash rate" versions. These are supposed to reduce effectiveness for mining of currencies like Etherium by about 50%, without impacting game performance or other applications, but to be sure of that we put a pair of GeForce RTX 3070 cards - one with LHR and one without - to the test.

Should you upgrade to Windows 11 for Rendering?

Written on October 8, 2021 by Kelly Shipman

Windows 11 is finally here, however, many popular rendering applications like Redshift and V_ray have not officially offered support for the new OS. So what kind of performance could be expected as of the launch of Windows 11?

PCI-Express 4.0 vs 3.0 Video Card Performance

Written on November 30, 2020 by William George

PCI-Express has been the standard for connecting video cards and other expansion devices inside of computers for many years now, and several generations of the technology have now passed. With each of those generations, the amount of data that can be transferred over the PCIe connection has increased. How much impact does that have on modern video cards? Is there any benefit to running a PCIe 3.0 card in a 4.0 slot, or loss if using a 4.0 card in a 3.0 slot?

Quad GeForce RTX 3090 in a desktop - Does it work?

Written on October 20, 2020 by Matt Bach

NVIDIA's new GeForce RTX 3090 24GB is an incredibly powerful GPU, but the power consumption makes it difficult to use even two cards in a desktop workstation. Are three or even four GPUs possible, or is the heat and power draw too high to be feasible?

NVIDIA GeForce RTX 2080 Ti PCI-Express Lane Scaling in OctaneRender and Redshift

Written on October 15, 2018 by William George

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.

GeForce RTX 2080 Multi-GPU Scaling in OctaneRender and Redshift

Written on October 12, 2018 by William George

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.

NVIDIA Dual-Fan GeForce RTX Coolers Ruining Multi-GPU Performance

Written on September 28, 2018 by William George

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.

Can You Mix Different GPUs in Octane and Redshift?

Written on June 28, 2018 by William George

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?
