    Question The Ampere architecture is designed more towards compute task vs sheer gaming?

    Good point. For production workloads, the CUDA license prohibits most companies from using consumer grade hardware anyways. But for research/hobbyist use, datacenter/cloud doesn’t make a lot of sense if your utilization is above 10% or so (based on current AWS prices, with 1yr amortization, I...

    Question The Ampere architecture is designed more towards compute task vs sheer gaming?

    The Ampere series is quite impressive for DL performance (of course, AMD lacking a coherent strategy in this space, and ROCm not "quite" working on even Navi just yet, etc etc). Performance scaleups more than potentially 2x 2080 ti makes the 3080 possibly the best buy in the space, even compared...

    I know Seagates are prone to failure but are they really THIS bad?

    Have one of those (rather, the 4TB model) in an external - after getting failures, I dug the drive out of the external casing and started using it as an internal backup drive. After the 500th reallocated sector or so, it wasn't good for even that (causing backups to fail every few days), and has...

    Laptop for playing recent Sims games (as well as average apps)?

    Hi, I mod for the Sims. Generally the Sims is not GPU bottlenecked, except in the most absurd scenarios. (it is a very old game for that reason). A HD 4400 would deliver adequate performance at medium: http://www.notebookcheck.net/Computer-Games-on-Laptop-Graphic-Cards.13849.0.html However...

    Should I get a 780 Ti?

    Probably more sense to go shopping for bargain basement 290s from ebay at this point: I've seen reference cards go for around $200+shipping and some aftermarkets go for $250 (no Tri-x though). Those probably still have an effective warranty that you can utilize in case of fan death or something...

    How long could an SSD for read only purposes last?

    Something I've always wondered: is degradation a Poisson process, or does it result in catastrophic failure? I'm referring to a particular usage app that has recently gained popularity: storing private keys (cryptocurrencies, etc) in vaults for decades by writing the key hundreds of thousands of...

    What happened to edge only anti-aliasing?

    As I mentioned, implementing MSAA directly on deferred rendered engines (the vast majority of "new-ish" games) does not work. You need to get the actual geometry (which means that developers need to spend time modifying their engines; or you have someone like Boris who does it for free in ENB)...

    What happened to edge only anti-aliasing?

    Compare the performance of MSAA + transparency AA + temporal AA vs some MLAA technique like FXAA. Then realize that most people still have relatively low res monitors / TVs that hide the blurriness of FXAA / don't allow the advantages of MSAA to be apparent. As a developer, what would you likely...

    What happened to edge only anti-aliasing?

    Also - deferred rendering techniques (which produces many of the "fancy modern effects" in today's games) are generally not compatible w/ multisampling techniques without "a lot of work" (work, being relative). http://en.wikipedia.org/wiki/Deferred_shading Still, things like ENB (developed by a...

    Anyone else getting bored with PC hardware?

    The movement has been away from the middle to the extremes. (Think of the "hollowing of the middle class" that's been a global phenomenon since, say, the 50-60s). Ultra light weight / portables: Mobile, watches, wearables, smart "everything". Ultra high-end computing: Big data, simulations...

    Does A Person Really Use Over 1TB Of Storage

    One of the emerging areas is scientific data. I'm a relative lightweight (only a few dozen GB of microscopy images here and there), but stuff like raw sequencing data can run into an entire TB PER sample. It's no surprise that any moderately productive sequencing lab can rotate through entire...

    Forcing Triple Buffering Externally for Skyrim - Why?

    If you're speaking about the complete absence of physics on Morrowind, you'd be right. I presume Havok is the cause of a lot of bugs in Oblivion and Skyrim (more so in Skyrim, now that the (well understood) animation system was replaced by Havok Behavior, while admittedly superior, is...

    Forcing Triple Buffering Externally for Skyrim - Why?

    As a um... consumer and (mod) developer for Gamebryo from the 2000s (yea, Morrowind), yes it's possible to get Gamebryo in a state where it doesn't crash. It's also possible to get a 100 on your organic chemistry exam, or run a three-minute mile, or make your Windows install perfectly secure...

    Beginning to hate my rig -- microstutter!

    Wondering ... how's your DPC latency? Run LatencyMon or DpcLat and see what you get. Windows 8 was known for latency issues, but it's certainly not unique to that.

    Mining cards starting to hit the used market

    Crashplan: Seed Drive Super Slow

    Set dedupe to minimal or off. I don't have the blog post handy, but default dedupe settings scale as a function of O(log(n)) [with CPU power (usually limited), not bandwidth (usually not limited, with modern cable connections)], which is terrible if your dataset is millions of files / TB in...

    How to protect your data guide

    Backblaze / crashplan. Make sure your client also has some way to protect the settings panel (with a password DIFFERENT from your account password). A malicious attacker could possibly wipe out your backups, if determined/spiteful enough.

    what is double precision useful for?

    There are (very) few instances where double precision in general (not talking about graphics here) makes sense in gaming -- generally, they tend to be similar to the scientific applications (in other words, "simulation"). I believe EVE Online uses double precision internally, which is necessary...

    Would a gtx 780 TI be enough to power this

    Most games probably (though Crysis 3 could do with a bit lower settings), but search for the 5760x1200 scores on Bench (http://anandtech.com/bench/) and add a bit to account for 1080p instead of 1200. Oh right 780 TI is not on there. Guess you could compare it to, say, the 690.

    Game smoothness with single GPU

    Is this true microstuttering or just stuttering? Microstuttering is a specific phenomenon that occurs with multi-GPU setups. Stuttering can be caused from everything from background processes, to overclocks, to disk accesses.

    When my ssd arrives, I can use my old primary drive as a backup...

    Yes, you can. No, you still want (rather, need) an external, or better yet offsite backup solution. Fires, floods, lightning, thieves don't care whether your data is on an SSD or a hard drive.

    We've all heard this before... friend had a drive failure (IDE).

    +1 to online backup and Crashplan (my favorite provider). 2TB backup drive died a few months ago (oddly it was one of the newer drives, but just past the warranty). Crashplan had no problem restoring nearly 1TB of data over the cloud in a week (also thanks to Comcast), and the only thing lost...

    Password list security

    Cryptocoin Mining?

    Bitcoins are to "blue chip stocks" as altcoins are to "small caps". During each recession/bear market, there is a flight to safety. During each bull market, there is a flight to risk. Has been this way for hundreds of years.

    280x Prices up 20%?

    Here's the thing though: both AMD and Nvidia cards can game as well as mine. Prices there right now (for both companies) are dictated by mining performance, not gaming performance. It's just your personal assessment of which is more important to you, right now as well as in the lifetime of the card.

    nVidia equivalent of r9 280x?

    Chip-wise, a 770 is basically identical to a 680 ( http://www.anandtech.com/show/6994/nvidia-geforce-gtx-770-review ) but with 7Ghz ram. So, one or the other depending on sales/ebay/etc.

    280x Prices up 20%?

    In that case, you might just as well buy the coins. (This has been discussed ad infinitum on another thread, so I won't go there). It's the people that are sinking in mining rigs that cost the same as a car, without regarding difficulty that I'm worried about.

    280x Prices up 20%?

    But difficulty has been increasing by over 100% a month recently. So $1200 the first month, $600 the 2nd (and that's assuming that prices remain at these currently lofty levels). Very timing sensitive. And good luck trying to dump your now chronically oversupplied GPU in a slow (post-Christmas)...

    280x Prices up 20%?

    Yea, the pricing is so wacked out right now that I'll be getting an upgrade from a 7950 to a 780 (with newegg's current deal) for the price of a decent dinner. In fact I can't remember any other video card purchase that I actually made money on (mining profits excluded).
