Blender 2.81 Benchmarks On 19 NVIDIA Graphics Cards - RTX OptiX Rendering Performance Is Incredible

Tue, 11/26/2019 - 20:46
Last week marked the release of Blender 2.81 with one of the shiny new features being the OptiX back-end for the Cycles engine to provide hardware-accelerated ray-tracing with NVIDIA RTX graphics processors. Long story short, OptiX is much faster for Blender than using NVIDIA's CUDA back-end -- which already was much faster than the OpenCL support within Blender. For your viewing pleasure today are benchmarks of 19 different graphics cards looking at the CUDA performance from Maxwell to Pascal to Turing and then for the RTX graphics cards also the OptiX performance.

Linux 5.5's Scheduler Sees A Load Balancing Rework For Better Perf But Risks Regressions

Tue, 11/26/2019 - 19:45
Ingo Molnar sent in the kernel's scheduler changes along with the other material he is overseeing for Linux 5.5. With this next version of the Linux kernel comes a rework to the Completely Fair Scheduler's load balancing logic. This is helping some workloads at least but with the intrusive change runs the risk of possible regressions...

Linux 5.5 To Finally Wire Up EFI RNG Code For x86 As Another Source Of Entropy

Tue, 11/26/2019 - 16:14
Since 2016 the Linux kernel on ARM has invoked the EFI random number generator (RNG) protocol for serving as an additional source of entropy during early boot. With Linux 5.5 in early 2020 that code is finally happening for x86/x86_64...

AMD Ryzen Threadripper 3970X / 3960X Linux Benchmarks

Mon, 11/25/2019 - 22:00
After the embargo on the Intel Core i9 10980XE expired a few hours ago, now we are allowed to share the performance numbers on the new AMD Ryzen Threadripper 3960X and 3970X processors. These new Zen 2 HEDT CPUs pack a real performance punch, but do come in as more expensive than the i9-10980XE and there is one boot-stopping Linux bug to mention with a workaround... But besides that lone Linux support caveat, the Threadripper 3960X and Threadripper 3970X absolutely dominate in performance.

The Workaround To Boot Linux On AMD Threadripper 3960X/3970X Systems

Mon, 11/25/2019 - 22:00
As outlined in our AMD Ryzen Threadripper 3960X / 3970X Linux review, these new Zen 2 Threadripper processors are phenomenal processors that offer significant uplift over earlier Threadripper CPUs and easily dominate over Intel's Core i9 HEDT competition. But there is one big issue right now with the Linux support: on Ubuntu and the like, it doesn't boot without a workaround. Here's that workaround for easy future reference...
