Fsck me! Seriously.

You understand the concepts of economic curves crossing, correct? Please step up, or shut up.

Like, seriously... I'm surprised the moderators tolerate your noise (perhaps they find you amusing; a bit like a court jester (and we all know what happens to them)).

 2021-11-10, 21:06 #13 VBCurtis     "Curtis" Feb 2005 Riverside, CA 13·397 Posts If you had to change your motherboard because of a new GPU card, that would mean the market for that GPU would be tiny- a 2021 GPU can be plugged in to a ~2012 machine, or even older. That's by design, and it won't be changing in the next two generations. It's possible an upcoming GPU will require PCI 3.0, but that has been around a while. The power plugs for GPUs also have not changed in a while- as long as your power supply has the right plug, it matters not which generation the GPU is. You could plug a GeForce 3xxx or 2xxx into your current motherboard; you don't need a new computer. you might need some new fans to exhaust the heat, or a bigger power supply, but the motherboard isn't a restriction.

I'd rather to have a new machine since my current old PC already has some cooling problems.

I'll have the 1000W power supply to support the new machine, so the fans and heat won't be the issue again.

The DDR5 memories will be nice to have because they are likely to speed up the P-1 tasks. Intel 12900K is better from this perspective which AMD Threadripper probably won't support this format until the Zen 4 edition.

If I have 2 machines, 1 new and 1 old, then I can assign

P-1 to old PC CPU, TF 2^73 to 2^76 to old PC GPU
PRP to new PC CPU, TF 2^76 to 2^79 to new PC GPU.

You are of course aware your SNR is approaching zero? Easy to reflect against, though.

Look up "New Clothes" if you have the time to learn...

Complaints do not improve the ratio.

I point out that a new GPU works in your old PC to communicate that worrying about a 2024 GPU in a 2022 PC is unnecessary.

The size of your power supply has nothing to do with the quality of your cooling- you still need fans, and you still need to worry about heat. You're connecting two things (power supply and cooling) that have nothing to do with each other.

You are also mistaken about 12900 on DDR5 being better bandwidth than Threadripper on DDR4. Two channels of DDR5 (well, four half-sized channels as 12900 has) is less bandwidth than TR's 4 channels of DDR4. If you want memory bandwidth, gotta go threadripper or Xeon.

What I meant was the bandwidth per price. If I were to buy the Threadripper PC, the total price tag would be more in the $5,000+ instead of the$3,000+ for Intel 12900K.

Also that Threadripper 5970X seemed to take forever to reach the market, has been delayed at least twice.

It'll always be possible to add 2 more DDR5-5200 memory sticks with the cheaper price tag 1 or 2 years later which accumulate to 64 MB memories total.

AMD Threadripper Zen 4 6970X with DDR5 memories I assume, but I'm not going to wait that long.

Intel has tried to appeal to the middle class users who want the not so expensive CPU while gaining some upgradable options. It was indeed AMD's misstep that they didn't launch Threadripper 5970X this autumn as originally planned.

I really don't want stick with the DRR4 3200 memories, their prestige is no longer the best.

I have very deep nearsightedness and astigmatism, I cannot see the parts very clearly even using the flashlights during the daytime.
