Re: Any Spam eaters here(Yes the canned meat product)?

I will not eat it from a can.
I will not eat it just like ham.

I will not eat green eggs and Spam!
Sam I am!

Just kidding. I don't eat it often but thin sliced and crisped spam goes great in a lot of recipes and even makes a good bacon substitute (sacrilege I know).

Speaking of Buffaloes, with the top-end Epyc chip supposedly costing north of $4000, that pretty much dashes my hopes of getting a 2P Epyc server with 256-512GB RAM.

I really could've used all 128 h/w threads, too. *sob* :cry:


Just buy two single-socket servers and make a cluster.

Re: End of an E®A

When I was a kid my parents would drag me (often unwillingly) through every hick town you can think of in the back country of Pennsylvania.

My metric for whether a town was civilized or not was that civilized towns had a Radio Shack.

Re: Skylake X: Bye Bye Rings, Hello Mesh

The more we advance, the more nuanced process layout and memory access have to be. That said, it probably won't make much difference for consumers. Intel could easily "tile" 4+ cores into a node without much engineering if they've already done 2. They generally aren't so shortsighted to d...

Last week, Newegg on Ebay had a 1080 Ti (Gigabyte non FE edition with 3 fans) for the same price. Is a 4GB Rx 480 really more efficient for mining than a 1080 Ti?

yeah it seems the only time intel really pushes hard for change is when AMD gives them a reason to do so, otherwise they coast along barely inovating.

So there was quite a bit of commentary about the purported RyZen price cut. recently. And it does appear that some retailers did cut the for-sale prices of RyZen chips. That's not being denied.

NVLink may still have some advantages for dedicated high-end Nvidia GPU systems, but it's never going to be a standard that will replace PCIe in the vast majority of systems, even for GPUs.

Re: PCIe 4.0 ALMOST Ready

It could definitely be useful.

Even so, we will still be better off increasing the number of lanes instead. Will we? Lane...
