Re: Will high GPU prices kill off PC gaming?

A NAS would probably be a better solution than keeping backups, but who has that kind of $? You mean in addition to keeping backups, I hope. A copy of your data on a NAS doesn't mean it's a backup just because it's not in your local machine... On-topic, it does appear that GPU prices are returning ...

Re: Will high GPU prices kill off PC gaming?

Most of my HDD failures have been more gradual. I wish I could say the same. Almost every drive failure I've experienced has been very sudden with very little time to respond, if any. SMART monitoring helps dramatically in terms of detecting an impending failure, but the last few drives I've had fa...

Re: Will high GPU prices kill off PC gaming?

Sigh. I shouldn't respond, but WTH. Sure, waco, a few things. 1) I'm specifically talking about the $/GB value of a crap no-RAM-cache TLC drive against 7200RPM HDDs in a RAID 0+1 configuration - keep that in mind for the below. 2) SSDs are tiny and in my experience, never less than 75% full at any ...

Re: Will high GPU prices kill off PC gaming?

JBI, the good news is that a lot of older MLC drives are still available on the market for essentially the same price as the new crappy RAM-less TLC drives. For as long as that's still the case it's possible to get more for your money. Inherent unsustainability is unhappy-making, though, and it's g...

Re: Will high GPU prices kill off PC gaming?

High end PC gaming costs have gotten out of control IMO. As long as this system stays working I'm done buying anything for many years unless I can sell off this 1070 later for a decent amount. IMO, they're the cheapest they've been in...ever...really. Look at what $500 could purchase a decade ago, ...

Anything that's memory latency or bandwidth bound that doesn't fit in GPU memory. In my line of work, that's basically all of the problems we run (physics simulations).

Re: Dumb idea/thought experiment

HBM's performance isn't ideal for CPU-side use. If the workload is all about sequential bandwidth, it's great, but if you've got more random access patterns, it's garbage. I disagree with this statement. A very slight increase in memory latency (on the order of 15% or so, worst case) isn't enough t...

Re: Safest way to prep a laptop for sale

Modern drives tend to have firmware and parameters on a track that's only readable by the drive and not by the host. If you use a bulk eraser on them then you have likely erased that and the drive is useless. Given the high coercivity of modern media, you need a fairly powerful magnet to degauss re...

Not really the same thing, but SMR drives actually *do* partially erase previous valid data with new data: https://en.wikipedia.org/wiki/Shingled_magnetic_recording Yep.

I never got the idea of multi-pass erasing. If old data can be read after being overwritten, why don't HDD manufacturers use that to double or triple the capacity? :) Because recovering that data is *incredibly* slow and expensive. :P I don't even get the option of a DoD or NSA approved erase...I g...

Why does the router interface matter at all? If you don't have more than 1 Gbps of Internet connectivity, it's literally a non-issue. It matters when most home networks simply connect to the router making it the de facto switch for the network. I could get a 5G or 10G switch and route the entire ne...

The router assigns the internal IP addresses, no? Doesn't all internal traffic pass through the router at some point? Wouldn't the slowest link in the chain constrict all traffic to that speed? Only internal traffic that needs to leave your local network is routed through your routers WAN port. Swi...

Dunno about routers, but the ASUS XG-C100C that launched is a ~$100 10Gbps NIC. It also specifically supports 2.5GBASE-T and 5GBASE-T links. Given ASUS already makes some 10GBASE-T switches I would tend to think that means ASUS will be launching some updated consumer routers within the year that pe...
