Nvidia has introduced that it’s going to take steps to make sure RTX 3060 GPUs wind up within the fingers of avid gamers, not crypto miners. On Thursday, the corporate mentioned it could launch a brand new lineup of CMP (Crypto-Mining Processor) playing cards, whereas additionally proscribing the utmost efficiency of the RTX 3060 when mining Ethereum.

RTX 3060 GPUs will solely mine Ethereum at 50 p.c of their potential hash fee attributable to driver-level restrictions. In keeping with Nvidia, its new CMP playing cards will run at full velocity. These playing cards lack video outputs and so they provide each decrease peak voltage and decrease most core clocks, with the intention to enhance mining effectivity.

Nvidia claims CMPs shouldn’t be known as video playing cards or GPUs as a result of they lack the elemental hardware to satisfy that position. That is true, so far as it goes, nevertheless it’s not as a result of the playing cards really lack help for “RTX real-time ray-tracing, DLSS AI-accelerated picture upscaling expertise, [and] Reflex super-fast response rendering for the very best system latency.” All of that functionality continues to be baked into the CMP — you simply can’t make sensible use of it.

This initiative is supposed to extend the availability of RTX 3060 playing cards in-market.

Nvidia’s push to rebrand mining GPUs as “CMPs” makes some goal sense, because you actually can’t use these playing cards for gaming or video output, however an precise custom-designed CMP wouldn’t simply be lacking some video outputs.

A processor designed for mining Ethereum could be thought of a particular sort of ASIC. A GPU design repurposed for mining Ethereum with none further customization work would at the very least embody further processing cores quite than dedicating the bodily silicon to ineffective gaming options. Nvidia calling this iteration of the RTX 3060 a CMP is smart from a advertising perspective, however from a technical one you’d anticipate the chip to be a bit of extra specialised than these playing cards really are.

Will This Truly Assist Something?

We’re glad to see Nvidia making an attempt to repair this case, nevertheless it’s not clear how a lot that is going to assist. We must always see some enchancment in RTX 3060 availability, however GPUs are laborious to seek out proper now throughout the product spectrum, and meaning there’s further upward worth stress on any out there GPU, even when we ignore cryptocurrency mining demand.

If TSMC and Samsung are at present capacity-constrained and transport each chip they’ll manufacture, then splitting the pile of RTX 3060 GPUs into “CMP” and “GPU” buckets simply means there are much less chips out there to fill demand in each segments. Unmet demand for CMP playing cards will waterfall into the GPU area, even when GPUs are disfavored for these workloads. Specialised playing cards may blunt the impression, nevertheless it’s uncertain they’ll fully offset it.

If the complete market wasn’t provide constrained, Nvidia would have extra choices. Effectively-priced CMP playing cards might be counted on to divert consumers from the GPU market, and there could be sufficient stock to satisfy demand. With GPUs laborious to come back by at each worth level and each TSMC and Samsung operating at most manufacturing, this seems to be a bit extra like subdividing the identical pie to carve out one other slice. We’d prefer to be improper on this, as a result of the semiconductor market wants all the assistance it may get. But it surely’s not clear that limiting the RTX 3060 alone on this style will meaningfully enhance GPU provides in and of itself. We’re hopeful this may assist on the margins, however solely ramping up

On October 25, Apple will release iOS 15.1 and iPadOS 15.1. What we know so far




Apple released important updates for iOS 15 and iPadOS 15 on Tuesday, to address several issues and a severe security hole affecting the two platforms. Now, according to reports, Apple is working on iOS 15.1 and iPadOS 15.1 builds for iPhone, iPod touch, and iPads.

Also, Twitter user named RobertCFO received confirmation from an Apple Product Security Team member about the final build’s release date. On October 25th, according to a leaked email that was then deleted from Twitter, iOS 15.1 and iPadOS 15.1 will be released, a week after Apple holds its conference.

This follows Apple’s general software upgrade policy, which is to release new updates a week after its events.

PSA: Mining Chia on an SSD Will Completely Wreck It in No Time Flat

When SSDs first started transport in shopper merchandise, there have been comprehensible issues about their longevity. Time, steadily enhancing manufacturing methods, and a few low-level OS enhancements have all contributed to solid-state storage’s popularity for sturdiness. With experiences praising SSDs as provisionally extra dependable than arduous drives even beneath heavy utilization, it’s straightforward to see how individuals may not see the brand new Chia cryptocurrency as a serious trigger for concern.

It’s. Chia is first plotted after which farmed, and whereas farming Chia takes little or no in the way in which of processing sources, plotting it should completely hammer an SSD.

It’s been years since we talked about write amplification, but it surely’s a difficulty that impacts all NAND flash storage. NAND is written in 4KB pages and erased in 256KB blocks. If 8KB of information must be changed out of a 256KB block, the drive might want to learn the unique 256KB block, replace it, write the brand new block to a unique location on the drive, after which erase the earlier block.

Write amplification has been an issue for NAND for the reason that starting and a substantial amount of work has gone into addressing these issues, however Chia represents one thing of a worst-case situation. Right here’s an excerpt from a latest Chia blog post:

Producing plot recordsdata is a course of known as plotting, which requires short-term space for storing, compute and reminiscence to create, kind, and compress the information into the ultimate file. This course of takes an estimated 256.6GB of short-term house, very generally saved on SSDs to hurry up the method, and roughly 1.3TiB of writes in the course of the creation.

The ultimate plot created by the method described above is simply 101.3GB. There seems to be an order of magnitude of distinction between the full quantity of drive writes required to create a Chia plot and the storage capability mentioned plot requires when accomplished.

Motherboard producers have gotten in on the motion, with one Chia-compliant board providing 32 SATA backplanes.

Right here’s what this boils right down to: A number of shopper SSDs are actually unhealthy decisions for mining Chia. TLC drives with SLC / MLC caches will not be really useful as a result of they provide poor efficiency. Low-end and midrange shopper drives will not be really useful, as a result of they don’t provide excessive sufficient endurance. It’s important to watch out through which SKUs you buy and enterprise and enterprise drives are extra extremely really useful normally.

Don’t purchase a QLC drive to mine Chia.

Optane would appear to be a near-perfect match for Chia, given its a lot greater endurance, however I can’t discover any data on whether or not individuals have tried deploying it in massive sufficient numbers to have some concept of what efficiency and endurance seem like beneath the 24/7 load Chia plotters are placing on their hardware. Possibly any individual will put a rig collectively utilizing it, as a lot out of curiosity as the rest.

Past that, ExtremeTech recommends customers not try and plot Chia on any SSD they aren’t snug with dropping, and to not purchase an SSD for the aim until you don’t thoughts throwing it away if it dies far more rapidly than anticipated. Chia plotting is a worst-case situation for SSD longevity and it needs to be handled as such.

One notice of fine information: To this point, Chia mining has had a a lot stronger affect on high-capacity arduous drive costs than on SSDs and smaller drives. Hopefully, this continues to be the case.

Microsoft adapts OpenAI’s GPT-Three pure language expertise to mechanically write code



Microsoft CEO Satya Nadella introduces the brand new GPT-Three integration into Energy Apps in a recorded keynote tackle for the corporate’s digital Construct convention.

Microsoft unveiled new tools for automatically generating computer code and formulation on Tuesday morning, in a brand new adaptation of the GPT-Three natural-language expertise extra generally identified for replicating human language.

The aptitude, to be supplied as a part of Microsoft’s Power Platform, is among the fruits of the corporate’s partnership with OpenAI, the San Francisco-based synthetic intelligence firm behind GPT-Three. Microsoft invested $1 billion in OpenAI in 2019.

“The code writes itself,” stated Microsoft CEO Satya Nadella, saying the information in a recorded keynote tackle to open the corporate’s Build developer conference.

The characteristic is named Power Apps Ideas. It’s a part of a broader push by Microsoft and different expertise corporations to make software program growth extra accessible to non-developers, often called low-code or no-code growth.

Microsoft fine-tuned GPT-Three to “leverage the mannequin’s current strengths in pure language enter to offer Energy Apps makers the power to explain logic similar to they’d to a good friend or co-worker, and find yourself with the suitable system for his or her app,” says Ryan Cunningham of the Energy Apps staff in a publish describing the way it works.
