The Mighty Buzzard writes:Congrats to the wannabe APK noobtard for advancing the site's codebase despite me having extremely limited time to play. I added three lines of code and now Spam modded comments (and comment trees) auto-collapse and you can still moderate a comment as Spam even if it's already at the minimum score. Honestly, the folks using any other downmod on obvious Spam annoy me more than the noobtard does but that annoyance at least is now history. Changes are to hot code only, I'll put them in the repo as part of my next pull request.Suck it, noob. --TMBRead more of this story at SoylentNews.

takyon writes:Nvidia has announced its latest generation of gaming-oriented GPUs, based on the "Ampere" microarchitecture on a customized Samsung "8nm" process node.The GeForce RTX 3080 ($700) has 10 GB of GDDR6X VRAM and will be released on September 17. TDP is up significantly, at 320 Watts compared to 215 Watts for the RTX 2080. The GeForce RTX 3070 ($500) has 8 GB of GDDR6 and a TDP of 220 Watts. The GeForce RTX 3090 ($1500) is the top card so far with a whopping 24 GB of GDDR6X VRAM. The GPU is physically much larger than the other two models and it has a 350 Watt TDP.Nvidia's performance benchmarks should be treated with caution, since the company is often using ray-tracing and/or DLSS upscaling in its comparisons. But the RTX 3070 will outperform the RTX 2080 Ti at less than half the launch price, as it has 35% more CUDA cores at higher clock speeds.Nvidia also announced some new features such as Nvidia Reflex (4m53s video), Broadcast, Omniverse Machinima, and RTX IO. Nvidia Broadcast includes AI-derived tools intended for live streamers. RTX Voice can filter out background noises, greenscreen effects can be applied without the need for a real greenscreen, and an autoframing feature can keep the streamer centered in frame while they are moving. Nvidia RTX IO appears to be Nvidia's response to the next-generation consoles' use of fast SSDs and dedicated data decompression.NVIDIA GeForce RTX 30 Series | Official Launch Event (39m29s video)Previously: Micron Accidentally Confirms GDDR6X Memory, and Nvidia's RTX 3090 GPUOriginal SubmissionRead more of this story at SoylentNews.
