Re: Intel 10th-generation Comet Lake in 2020 on 14+++++ nm

Was there any hope in expecting that I could use the same Coffee Lake socket, or am I just naive? Comet Lake 14+++++ nm desktop CPUs (based on their existing Skylake microarchitecture from Core 6000, 7000, 8000 & 9000 CPUs) will use a new LGA1159 socket Right, I meant before this fact was revea...

Re: Subscription drops from Gold to Silver?

A dynamic downgrade from gold to silver seems like an oversight; the fairer policy would be to lock you into a tier at the time of purchase.

I thought with most things, it is the on/off cycle where most of the wear occurs. It this also generally true of compressors and other electric motor-driven stuff? However, there's another part that frequent on-off cycling can kill: the thermostat. What do you do if you can't find the original part...

To extend the life of those plastics, you may be able to use some lithium-based or silicon-based food safe greases.

I get that, but will the speed of running on only 4x K80's offset access to 28 cores that I can partition across my jobs?

If you want to agonize over numbers without any testing, you can look up the X470 VRM list to see if you're really buying a proper VRM for your Ryzen. If you want 144 Hz gaming, I would say that is still intel's territory. In real life most people are not going to pair a $300 CPU with a $1200 GPU a...

Vega 56 is a pretty good GPU. If I was you I'd hold on both, and start shaving shekels for a six core CPU of some sort. More headroom for the 600,000 random processes in a typical Windows deployment, something that usually isn't captured very well in a benchmark/review rig. Yeah, IK, but a new moth...

Yes, the problem is that CPU frame time can only be decreased by upping processing power, whereas GPU frame time is easily tweaked in graphics settings. If you choose wrong with the CPU, you're out hundreds of dollars, whereas with the GPU you can always pick whatever is within your budget and make ...
