Up until November 18, 2020 I would have suggested against the purchase of an AMD GPU for VFIO. But yesterday AMD launched its Radeon RX 6800 line of GPUs. Are the AMD Radeon 6800/6800XT suitable for VFIO?Continue reading “AMD Radeon 6800/6800XT for VFIO?”

A question that frequently pops up in VFIO or GPU passthrough forums is which graphics card to buy: AMD or Nvidia? And the answer often depends on whom you ask.
Some people will tell you to stay clear of Nvidia graphics cards since their driver detects the virtual machine and quits.
Others mention the “reset bug” that’s been haunting AMD graphics cards for the last couple of years (see Wendells video interview of Linux kernel maintainer Greg Kroah-Hartman). So what’s the story?Continue reading “Graphics Cards: AMD vs Nvidia”
I’ve been contemplating a PC upgrade for more than a year (see my post here). At first I considered staying with Intel and getting an i9-9900K CPU with integrated GPU on a Z390 motherboard.
Along came the AMD Ryzen 9 3900X that topped the benchmarks, including the Adobe Lightroom and Photoshop benchmarks (to be precise, it ranked #4 in the Adobe Lightroom benchmark, and a narrow #1 in the Adobe Photoshop benchmark). These good news about the AMD Ryzen 3900X were soon followed by reports about BIOS issues and VFIO incompatibility. At the very least, it looked like VGA passthrough was more challenging.
Then I read Bryan Steiner’s GPU passthrough tutorial for the AMD Ryzen 9 3900X and an Ubuntu-based Pop!_OS Linux host. Several users on the VFIO Reddit forum reported successful VFIO VGA passthrough with the AMD Ryzen 9.Continue reading “Upgrading my PC to an AMD Ryzen 9 3900X System”
More than a year has passed since I’ve posted about building a new PC. So what is holding me back from the upgrade? Time and money are considerations, but not the reason.
On paper, the AMD Ryzen 9 has outperformed Intel in most if not all tasks. The Ryzen 9 3900X beats the Intel i9 9900K as well as the Intel i9 10900X in multi-threaded workloads. The Intel i9 9900K can barely hold its ground on single-threaded tasks. Numerous benchmarks have shown that AMD is a clear winner.Continue reading “Hardware upgrade or what’s holding me back?”
