Show HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG A few months ago, I ordered a Minisforum UM690 for work. For less than 500 bucks, this little beast is equipped with the incredibly powerful 8 cores / 16 threads Ryzen 9 6900HX (4.9GHz) and an integrated RDN2 680M graphics card (the single thread performance of this mobile CPU is just 10% lower than my home 5800X desktop PC). I do some light gaming on my lunch break, and I was pretty impressed by the gaming performance of the 680M. Because of budget constraints at the time of ordering, I could only afford a single stick of Gskill - RipJaws 16 Go DDR5 4800 MHz CL34. I made a few benchmarks on multiple games, but most games I play do not come with a proper benchmark loop, so I used Unigine Superposition Benchmark to make a proper benchmark. Single 16 GB stick, 1080p, medium settings: 3022 (18.85 min fps, 22.61 avg fps, 31.85 max fps) Those results were good for an IGPU, but I saw a few articles saying that having two sticks instead of one could improve performance (never backed up with benchmarks or hard numbers). So I bought another stick. Here are the results with two sticks: Dual 16 GB sticks, 1080p, medium settings: 4969 (31.66 min fps, 37.17 avg fps, 48.96 max fps) Yep, this is a whopping +65% with two sticks! So, if you use a CPU with an integrated graphics card, you should use 2 sticks! February 15, 2023 at 03:55PM
Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
