    can signs of static damage be identified?

    Individual components are very small. You don't have to use dark side of the force levels of energy from your fingertips to damage something. In the case of static electricity, it is the energy.

    can signs of static damage be identified?

    Finished electronic products will have protection built in to resist static from causing damage. That doesn't mean they wont be, but it can take reasonable abuse and continue working. With components the requirements are different to that of a finished product. Major components like ICs will likely have some level of protection on their pins. Other components are generally less sensitive. It's practically impossible to tell how much damage there is. One day it'll work. Each zap can make it weaker, until some point it doesn't work right any more. Take some basic precautions and things will be fine. I've been building on and off of many years, and never killed anything, at least not by static...
  3. Is Teams able to host external facing conference calls then? I think that was a big limiting factor which means S4B is still the primary tool where I work. Maybe I'm not deep enough into Teams but is it even possible to have multiple things open at once? Only good thing about Teams is that I will be involved with certification testing for it, and in process of getting a load of new hardware to play with.
  4. Having a little thought exercise while I wait for it to arrive. Wont be until next week some time. I'm a little cautious with comparing across generations, as there were process changes with Kaby Lake which may give that a little advantage. Thinking more, the T series are probably binned for operation at lower voltage than standard chips.

    M.2 sata ssd to usb

    SATA interface is up to 6 Gbit/s, and USB3.0 is rated at 5.0 ~Gbit/s. How much you get out at the end will be further reduced by how efficient the controller is, and protocol overheads as user data is not same as connection data.
  6. I have too much stuff... so last night I bought a system containing a 6700T off ebay. Doh! The logic behind it was, I want a small, lightweight portable system for VR. Currently I have a 6600k based system in a Silverstone SG13 and it gets a bit toasty. It used to have a 6700k in it before I stole it for other uses. I also wanted the boost to thread count. Anyway, 6700T, I think should give a nice improvement to thermals, or will it? That's the question. The 6700k at a base clock of 4.0 GHz is 91W TDP, same as the 6600k at 3.5 GHz base. Now, the 6700k all core turbo is same as base so we can take this as an upper limit. The 6600k is 3.5 base, 3.6 GHz all core turbo. It should be less power in practice. Onto the 6700T, this is 2.8 base 3.4 all core turbo, rated at 35W TDP. What would be the actual power at 3.4 though? Still looking at quad cores of the era, the 6400 is 2.7 base 65W TDP. It's going to be interesting testing this one... in practice it might not be much less than the 6600k unless I use power limiting.
  7. Bandwidth. Before Turing, the SLI bridge gave 1 or 2 GB/s depending on version (from memory). PCIe 3.0 is roughly 1 GB/s per lane. So at the minimum 8x per card requirement, the bulk of available bandwidth is vis PCIe. There may be some other considerations, like only using GPU lanes and not chipset lanes which would immediately bottleneck you. With Turing nvlink gives 50GB/s so way more than before. Maybe they still keep the PCIe requirement as it is still available bandwidth.

    Intel to release 9990XE? Auction only part...

    I don't know how the auctions are being held beyond what's claimed earlier, but if they can compete against investor types who likely have very deep pockets, why not? Also...
  9. Was there a saving getting them together? I never saw the bundles on offer where I am so to me they practically don't exist. Price and capacity are two sides of the same problem. Configuration wasn't difficult, no worse than setting up a raid. It wont be for everyone, and they didn't expect that. It targeted a performance niche. As storage not cache, if you want random read performance, this is the only game in town. Nothing else short of a ram disk comes anywhere close, and that's going to cost you a lot more per capacity putting aside lots of other problems. You're over thinking it. It is no more difficult to use than any other drive. BTW I have Optane devices in the system I'm typing this reply on.
  10. I think the main scenario for Optane as cache is for the less than tech smart buyer who uses PCs. I have friends in this category. They're just not going to learn tech and want something that works. The scenario I'm thinking of is a laptop with Optane module, and a 1TB HD. Yes, you could arguably get a SSD+HD for similar cash, but the Optane route means the user doesn't have to care about where things are saved. It's the same device. It should also easily beat SSHDs as the cache in those is too small to be useful.

    Intel to release 9990XE? Auction only part...

    From: https://www.anandtech.com/show/13804/intel-core-i9-9990xe-up-to-5-ghz-auction-only So... basically it's a special product for HFT.
  12. There might be one reason to want to defrag a SSD, and that reason is filesystem fragmentation. While it doesn't matter much where the data is on the drive, you can get excessive fragmentation in the logical filesystem and that can slow Windows down. Now, this is in theory only. I've never taken any action on this myself, but I saw it in MS documentation a while back.
  13. They do have FP64, just not a lot of it. It is a segmentation decision to include or not include a given performance level. We had decent relative FP64 performance up to... whatever the nvidia 500 series was, and the last AMD card I had with decent FP64 was the 280X. It was downhill from there as the 28nm stagnation kicked in, and they nerfed FP64 on consumer devices to redirect that towards expanding other resource. Was kinda hoping the move to 7nm would be a return to those old days, but I guess not. The way things are going, Zen2 might be better value than their GPUs in this area.
  14. I'm looking at FP64 performance. Wx is comparable to consumer cards and doesn't come close to MI series.
  15. Ok, that blows the MI50 out of consideration for a FP/$ metric. The Titan V hangs in there, with Radeon 7 about 20% better bang for buck on up front cost. A concern for the Titan V is its ram bandwidth may be more of a limiting factor. I also did a rough estimate based on an i3-8100 and i7-7800X, CPU only, excludes other components required. They're still competitive in that sense, but of course would fall way behind once you do add necessary system parts. They're also competitive on bw/flop. Not enough info to do a good estimate on performance/W but it is probably on the lower end along with the 7, with the Titan V and MI50 in another league.
