> There's a very slight advantage of Intel CPUs in non-GPU constrained games (which means more or less 1080p only...). Very slight. Price/performance falls on Ryzen 3 so hard it's foolish to get an Intel for sure. it's not a huge advantage, but I'm not sure I would go so far as to call it foolish to buy intel at this point. if your only serious workload is gaming, intel seems like the obvious choice to me. you can ac…

We are talking a few percentage fps, at 1080p, where you are going from 200 fps to 220 fps. To call that a "significant" performance lead is silly.

Thats a 10% gain which might help you in some games to stay above the 144Hz or even 200Hz refresh rate of your monitor. Does not matter for most of us, but some hardcore esports gamers might care. I guess that's a very small minority though.

The best time to buy an EPYC Rome server was 10 years ago. The next best time is today. Edit: Okay, since some people are downvoting my joke, a more serious answer -- if your server farm is running out of space, and you're currently looking at renting additional space to accommodate your growth, EPYC Rome will take up substantially less space for a given level of performance. This is one case where it may make sense…

Physical space is almost never a constraint in data centers. It's power and cooling that are almost always the limit. If AMD's chips offer better performance/watt, that would make them attractive. The capital cost of purchasing a server tends to be a smaller number than the cost of the power to run and cool it over its lifetime. However, what also matters is vendor support. Lots of companies have contracts for pricin…

Less physical space = less cooling requirements

> "We designed this part to compete with Ice Lake, expecting to make some headway on single threaded performance. We did not expect to be facing re-warmed Skylake instead. This is going to be one of the highlights of our careers" Looks like AMD expected Intel would actually start to fight back a few years ago when AMD started the Zen and Rome cores, and AMD has been running full steam ahead since then. Meanwhile, in…

Intels 10nm node has been a disaster for years. This comes off as less "Intel has been doing nothing forever" and more "what they planned to do blew up in their face". That being said, if AMD never made Ryzen, you can bet your bottom dollar we would have been really enjoying ourselves 6 core hyperthreaded Ice Lake desktop and 16-24 core server CPUs next year for prices that AMD is now pushing 12 core and 48 core chip…

From what I heard, Intel 14nm was running a little late and management pushed the engineering team really hard.

As a result a bunch of the greybeards left, so for 10nm a bunch of institutional knowledge was completely missing and they had to learn everything again the hard way.

> I can't buy a Ryzen 3900X without paying substantially inflated ebay prices. I'm experiencing the opposite. There has been so many deals on 3900X that I have to constantly tell myself I don't need an upgrade.

I am genuinely intrigued. I've been going to my local Microcenters in the DC VA area for weeks now and they said they have gotten ZERO shipments in since release day of the 3900X and have a couple 3700X maybe on shelves. This doesn't necessarily completely invalidate my point though - distribution by AMD is clearly needing some work when one region is drowning in 3900X processors and a very wealthy metro area has non…

Consumer doesn’t really matter. Pretty much any IT admin I know is ordering one directly through wholesalers. I’m actually surprised people physically go to stores anymore.

The thing is you can't even get Ryzen inside a Dell or Lenovo machine - so for businesses it's kind of hard to get onboard with they hype. So intel is going to keep up market share until AMD can get into some prebuilt systems.

In laptops, you can. Lenovo launched the T495 and T495s a couple of months ago. AMD being a part of the venerable T-series is a huge testament to their come back. Not sure about desktops.

It's also available at lower price points. Typing from E495 which set me back like 600 EUR.

I don't care about getting it at a discount, I care about getting it at MSRP...

Then check out the discounted deal and mail them you'd like to pay extra

Good Morning Sir,

I hope this letter finds you in good health. Since I've seen that you are offering AMD 3900X at a discount, I'd like to inform you that I am not like those pleebs and would therefore like you to pay in full MSRP. Please let me know where I can send the goats.

I have the honor to be your obedient customer.

Zen was originally led by the same person as Opteron/K8/Hammer, Jim Keller... who now works for Intel. I think the situation is a bit different this time around though as AMD’s bet on TSMC is paying off in a major way while Intel continue to flounder in the fab space.

> AMD’s bet on TSMC is paying off in a major way Going back a bit further, AMD spinning off GlobalFoundries and then shopping around for fabs on the open market is definitely looking like a very good decision with hindsight. GF has also, since then, run into problems rolling out a next-gen node, and eventually cancelled their 7nm. Hard to say how much you can credit AMD for foresight there vs getting lucky, but being…

I don't think the foresight is in a particular manufacturer but in the fact that each successive fab generation was becoming more prohibitively expensive and more dominated by economies of scale.

I kind of want to see an analysis of the minimum viable volume of product to justify a new fab process going back over the years. Today it's just not feasible, compared to Noyce et al who could do it in their lab.

> For those with little time: at the high end with socketed x86 CPUs, AMD offers you up to 50 to 100% higher performance while offering at a 40% lower price. Unless you go for the low end server CPUs, there is no contest: AMD offers much better performance for a much lower price than Intel, with more memory channels and over 2x the number of PCIe lanes. These are also PCIe 4.0 lanes. What if you want to more than 2 T…

I'll be interested to see how long it will be before this devastates Intel's business. At the moment, there's literally no reason to buy an Intel desktop or server processor, so how many of the Intel purchases coming from OEMs and big cloud companies are just because of contracts that might let up in a few years?

For desktops gaming still drives a huge market segment where 9700k/9900k still have higher performance (esp if you overclock).

I think the one reason is that if you need the best gaming desktop performance Intel still dominates, but that little extra performance is coming at a very steep price. My next desktop of will be AMD+Nvidia. Now if only I could avoid the Nvidia tax for deep learning...

I’ve looked at a lot of the benchmarks and the difference was in the ballpark of 1-5%, which isn’t dominating from my perspective... did I miss a few?

Part of it is intel k parts have quite a bit of overclocking headroom while zen 2 has none.
