Devian666 posted:A good question. All of the CPUs I'm using for work and home (excluded my laptop) are all getting rather old (the memory in my workstation is DDR3 - I'm assuming this is rubbish by today's standards). An 1800x would be a major upgrade and with the fast floating point could be a leap forward that's faster than what I'm expecting. Could I make an alternative suggestion for your CFD workload? http://natex.us/S2600CP2J-Custom/ That, plus 2x E5-2670's, and 128GB of ECC DDR3 on 8 memory channels = 16 cores and 80-120 Gb/sec (edit: typo+realism) of memory bandwidth for ~$750. You can compare it to threadripper, but I don't think it can match the old dual Sandy Xeons in memory bandwidth per dollar. Assuming your current workstation memory is ECC you have spare parts there, and could even pick up a backup motherboard, and still stay under $1k.

Do you folks think it's fair to say AMD is the primary innovator in chip design, and Intel's the innovator in fab process design? Looking at 21st century CPU improvements, it seems like (correct me if I'm wrong) AMD was first to market for most of the major innovations: x86-64, multi-core, on-die GPU (Intel HD graphics came with Westmere, but AMD bought ATI in '06 and talked at the time of doing integrated graphics), integrating the northbridge, and now MCM to squeeze more performance while chips butt up against Moore's Law.

Most people don't think a lot about Intel hiring settlers for design work, you probably don't, but for some people their consciences and infinitesimal culpability nags and eats at them. Buying AMD, for those people, is a way to achieve what you've already achieved: not having to consider politics when they look at their computer cases. Let it be.

It's not that windows are bad per se, just that when you look into a PC case, it's an incredibly boring view. Like compare how much time you look in the case window compared to the monitor. It's not like it's giving you anything, except maybe smoke or burst piping, you could use to diagnose a problem with it. But to look into it for more than 10 minutes means admitting to yourself that this hobby might be boring, and being on a computer is a boring use of a life. But then you look back at the monitor.

If anyone ran OpenFOAM benchmarks on this new chip, that would test + stress the memory system in an important & common type of calculation. I can't afford to upgrade old sandy, but I could help walk an adopter thru a simulation. There isn't much to it, OpenFOAM has cases which are ready-to-calculate in their tutorial for laminar and turbulent flow regime cases. You can especially test core performance scaling, which levels out at around 8-10 real cores today.

Paul MaudDib posted:apropos of nothing but analogue TV has always been kind of a cool concept to me, since in contrast to modern systems where we are encoding information that then gets translated to outputs, analogue TV is basically "alright let's just broadcast the waveforms used to control the beam and the receiver can amplify them and push them into the hardware". You aren't broadcasting information, you're broadcasting a control scheme to get an electron gun to draw the information for you. It's a pretty elegant engineering solution to make the receiver as simple and cheap as possible. And the Philo Farnsworth fella who did a lot of work towards the development of television, also developed a home fusion reactor.

Man it's tempting to pick something up. This chip is to DDR4 what sandy bridge-to-haswell was to DDR3. Part of the longevity of that system is explained by how easy it's been to find DDR3 ram. When memory fabs, intel, AMD all switch over to DDR5, Zen2 and 3 will forever be the quickest chips to pair with all the world's DDR4. Maybe in five years I'll grab one of your old systems... this ivy bridge is just as fast as it was on the day I got it

Man these are tempting... I gotta wait for DDR5 tho. I'm doing big calculations on the old x220 Sandy laptop but the thing just runs so hot and it stutters in CAD. "It's just as fast as when I bought it" is still true tho, for a work laptop... But my calculations are memory-bandwidth limited... I will absolutely upgrade in late 2022. <2 years from InfFabric2.0 and DDR5's free boost. Seems like a choice of getting the best-ever DDR4 platform the fabs will ever make, or the worst DDR5.

To my mind, I'm fine buying $$$ DDR5 modules, if I can wear them out over the 2020s. Memory is typically the first thing to die, them and HDDs. All we know is that Zen 3 will be the fastest architecture using DDR4, but Zen 4 will be one of the slowest to use DDR5. So better odds of wearing the memory out, getting my money's worth, out of DDR5 modules than 4, since I can upgrade CPUs (thankfully AMD's got the ball, during the memory transition). It's both a good time to upgrade, and a good time to wait! I really like the idea of free ECC and crazy mem bandwidth for fluid dynamics simulations, kinematic simulations.

DrDork posted:Are you the type to overvolt the gently caress out of your RAM? Because absent that, I don't think I've ever heard of RAM dying in normal use in under like 5 years, and even then the only deaths I've seen have been at enterprise level installs (outside DOA / infant-mortality deaths, anyhow). I don't overclock, just intend to use it till it breaks. I think I've replaced 4 DDR3 sticks from age, between 2 computers. But the workstation had pre-owned 8x8GB -- Murphy's Law. I also skipped desktop DDR4/USB3. Don't want to be caught holding the bag (of old computer parts). I'm really just waiting for my old stuff to break. I'm holding the bag now on 320GB of 10x32 DDR3-1866, the fastest, fattest DDR3 memory ever made, that I found on SA-Mart, years ago, and justified for $300 (any homelabbers want it? If you need big capacity for a calculation, you're in used DDR3 world. Just as fast as when they were made, and unused by me...) I think that answers it, actually, for me. For big memory capacity calculations, I'll accumulate DDR4. I most typically run out of RAM in a big calculation. Just not going to make the mistake I did with DDR3, getting really specific server parts, and letting construction of a big old RAM workstation become a whole thing.

Fujitsu also designs laptops where RAM, SSD, wifi, battery are all user-serviceable. Mine also has a slot which normally holds a 2nd battery, but can also serve as 2nd HDD caddy, or bluray player. Handsome Japanese design, all around, I'm not sure why they aren't more widely used. Low prices on ebay, for those in the know.
