General Computer Thread

Looks like AMD has got intel running scared. With the approach of the Ryzen 3Ks, it's being claimed that intel are going do drop their prices.

While not quite matching intel's pure performance the AMD chips are beating the pants off them on a bang per buck basis.

And speaking of Ryzen. the mother-in-law found her Dell with the spinning rust was too slow so back to Costco it went. Now has one with a Ryzen 7, 16GB ram and 512GB SDD. Much much quicker due to the SSD though personally I don't think the screen is quite as good even though they're both same model range from Dell - the first one had a touch screen.

Though don't think either of the dell screens are as good as the IPS panel on the wife's Asus Vivo book.
 
Performance per watt is also great with Ryzen, and they don't have the security holes Intel has, in bad case scenarios you'll lose between 18% and 40% performance...
 
I think we're pretty close at what is possible with the current generation of tech, 7nm, okay, 5nm okay, below that, no idea, creating reliable CPU's is getting harder and harder, the smaller the production node the more fragile they become, old Pentium chips had a 10 year warranty on them, scientists say that those old CPU could last about 30 years or more in constant use.
But there are new technologies explored so who knows what happens next.

But isn't it the smaller the transistors get they start having effects that hinder performance?
 
Yep, electromigration breaking stuff, transistors source to drain leakage and other neat scientific stuff, I think heat also will become a problem, smaller CPU dies have a smaller surface area so heat can't be transferred away as easily.

I read something about quantum effect when you make dies at super small scales.

Just because I like to push my hardware, I decided to see just what the Ryzen could handle on a typical day, if everything was needed at once.
So I started up Plex, had a few movies running on a few TVs that way.
Then I started up VR, and ran a simple VR game.
Started GTA V in highest settings.
Ran a system diagnostic across the board.
Loaded up my favorite image editor and started working on a 100 MB image file.
Opened all of my web browsers (I have three), and loaded about two dozen tabs in each, all on various websites.
All at the same time.

The computer handled it all like a champ. No freezing, no slow downs, the movies kept playing without a hiccup, too. Have I mentioned how much I love AMD and couldn't wait to switch back to it after years of having to stick with Intel? (I still love that little FX-6300 chip and am going to donate a system to a family in need, so they get to enjoy it too!) If not, let me say it again: I love AMD, have been an AMD fan for all of my adult life, and am so tickled that the Ryzen's just one HELL of a chip.

That is bigly impressive.. Ryzen looks like it's very versatile and powerful.

I'm still using an FX 6300 because it is all I can afford at the time and my 4 year old GPU runs nearly everything on high at 1080p
 
I think heat also will become a problem, smaller CPU dies have a smaller surface area so heat can't be transferred away as easily.
I think you have that the wrong way round as a general principle. Small things lose heat more easily. Surface area scales as R^2; volume, mass and total heat capacity as R^3. Therefore, the larger an object, the slower it cools down. Small animals have trouble retaining their body heat in cold climates.
 
How convenient! Isn't it?
Same kind if "accident" happened halfway '90's with RAM chips, a factory of epoxy resin suddenly was destroyed in a fire and RAM prices surged.. coincidently Windows 95 came out JUST THAT YEAR! which needed 8MB RAM while most computers had 4 MB or less.. I still have so called topless simms in my collection, they supposed to use less resin.

some of the posters who responded to the article on anandtech did wonder about the convenience of it though some of them brought up the flooding that screwed up HDD production a few years back.

Before Windows 95 there was was a big spike in ram prices are few years prior that pretty much killed off OS/2.
