Topic: Meltdown and computer update

Was going to update the computer, but was not in time that like even it is good with the registration of the latest news. On what now that to look? To go over in camp AMD from them Threadripper? How it generally, tried who? Or not so it is terrible Meltdown as synthetics paints also a horse-radish with it and ? The computer is necessary for programming,  and operations from a photo (1-2 Gb of a photo in the Photoshop). It is a lot of kernels more shortly (well 6 at least), it is a lot of storage (well 32 at least) and that it is not so noisy. Under the budget for 4 without the monitor to get out not hunting. The computer did not collect years 10 as well as after Meltdown learned about modern lines  a lot of the new. Councils, recommendations?

Even if do not let out any changes for kernels, except stupid switch-off of display, always there will be a possibility it is switch-off to forbid - threat not that level forcedly to disconnect display at everything, sensitively losing in productivity.

I think, here speech of, whether procorfs of productivity as a result of patches are terrible, instead of whether vulnerability is terrible. Too much more patches frighten me than a problem which they solve.

Too much more patches frighten me than a problem which they solve. So it is possible not to put patches, or to look for possibility of switch-off of modes which they install.

G> in ten with it of a problem. A C other OS exactly same that MacOS that Linux. And it is correct. Meltdown - a piece very easily exploited. With Spectre not so it is terrible.

In respect of productivity cheaper ryzen (5 1600 or 7 1700), for the account  numbers of kernels they have total productivity the best i7-7700k, but in an one-flow more slowly. Though with a patch from meltdown on some types of loading now will explicitly faster)) If in operation you do not use intel-specific things/not you climb on processor level, amd probably the best variant. Or to wait year-two the following architecture in which correct problems with access check to storage.

To go over in camp AMD from them Threadripper? How it generally, tried who? Or not so it is terrible Meltdown as synthetics paints also a horse-radish with it and ? Looking with what to compare Threadripper.  productivity from meltdown goes in a specific juz-case - context switching. Considering that processors from Intel in an one-flow faster AMD if not to look at the price, the Intel will be better. If to look, AMD and to Meltdown were better in a budgetary segment, as far as I know. MA> the computer is necessary for programming,  and operations from a photo (1-2 Gb of a photo in the Photoshop). It is a lot of kernels more shortly (well 6 at least), it is a lot of storage (well 32 at least) and that it is not so noisy. On - you is ideally suited 8700K, if hunting to be confused, the dispersed. Judging by the description of your tasks, kernels at you will stand idle 99 % of time, productivity in the remained 1 % of time therefore is important and much bigger productivity of Intel here will be by the way. ThreadRipper it is ideal for those whom to eat than load all kernels for a long time, thus it would be desirable to take the effective decision at the price either to receive ECC or to receive many PCI-lines. Still a variant - to wait for following generation of Intel (I think half a year-year a maximum), there promise the 8-nuclear processor which will work most likely on the same 5GHz, as well as current leaders. Noise depends on cooling system, instead of from the processor. At me  is more silent, than , though power incomparable.> under the budget for 4 without the monitor to get out not hunting.

The photoshop now uses a multithreading in a tail and in a mane, therefore all kernels  will be involved. And still  actively uses  mathematical libraries. There is a probability that the same calculations on Rajzene give on the order (it is had similar  from users). Therefore I would take Rajzen to test on purpose a software is exceptional, but not for the main operation.

Same not remote control over my computer - at the best the password what steal, and that is should be added so much, that it turned out. Thus everywhere where it is important - two-factor authentication so too it is not terrible. It it is necessary to know whom and what for to break. Here  it is terrible. And vulnerability is terrible, and on typical   it is terrible - from the point of view of productivity falling.

SVZ> Therefore I would take Rajzen to test on purpose a software is exceptional, but not for the main operation. Taking into account noticeable reduction of price, 1900 now even will be cheaper, than 8700. And it already and for the main operation (taking into account Meltdown) can quit very much even very much.
