AMD Ryzen 2 (Pinnacle Ridge)

Recommended Posts

Next step down is i7 9700k for $420 but might as well go Ryzen at that point.

So price per value is a great topic which I recently saw a great summary by Linus and it has been my feelings as well for a long time.

Go to 1 minute 10 seconds (on mobile so cant put it in myself)

Well I did find one reason to wait if I'm assuming this next system to last 3-6 years. Interesting in the new AVX-512 instructions that Cannon/Cascade and Ice Lakes will bring, in particular the VNNI instruction and maybe the VAES instruction set.

I'm fairly certain Intel 10nm isn't coming anytime soon.  There have been multiple insider reports that the yields are currently atrocious (<10%) and that they have no clue how to fix them. 
I have a personal rule when it comes to technology about not extrapolating or reading too deeply into far off announcements.  It's one thing to delay a purchase because a new GPU/CPU launch is right around the corner (ryzen 3000 series being a good example), but it's totally different when you're delaying because Intel might one day figure out how to make their 10nm chips work. 

I clicked through that linus tech video and wanted to blow my brains out.  Even in his "gaming" segment his charts are recommending spending 40%+ of the budget on a cpu/mobo.  That's going to leave you with a real shitty system considering current RAM prices, not to mention a PSU or more importantly GPU.  The idea of calculating value add is a decent one, but I don't like his methodology. 

Again, looking from a price/performance ratio (and that's being kind and ignoring current intel availability problems) the ryzen 2000 series provides very similar performance across most tests for dramatically lower cost.  I personally would have a really hard time justifying buying a 9900k or 9700k when I could pick up a ryzen 2700x instead.  Again it's not that the 9900k is a bad CPU, it's currently the best "mainstream" CPU, but it's priced like there's no competition.

I can only tolerate Linus for short periods of time but I usually agree with this conclusions. 

In that video he does not recommend the 9900k in any of his configurations:

Rampant speculation.  Currently AMD is going to be giving a keynote at CES in January.  Most people expect serious CPU/GPU announcements, followed by a launch a bit later. 

This guy's channel has very long form videos that go over various tech news and speculation.  His AMD speculation is that we'll be getting a new Ryzen series (that looks similar to Intel) the Ryzen 9 series will be 16c/32t.  They might also do a silly 50th anniversary chip which looks something similar to Intel's i7 8086k. 

Overall if AMD does end up pushing all the core/thread counts up substantially, this could be scary times for Intel, mostly in the data center market, where they're already starting to lose ground.  On the system builders market, I've heard Intel is straight up slashing production and sending chips to their data center unit because yields are low and they can't meet current demand for new CPUs.  That's part of the reason why some of the new Coffee Lake Refresh is so hard to find in stock. 

EDIT: Here's a chart showing basically the same set of leaks.

This is interesting.  A while back there was some weird benchmarking with 32 core threadripper CPUs and someone finally figured out the issue is a windows problem.  I wonder how this will affect the AMD 3000 series as the rumors are these CPUs will run all the way up to 16c/32t.

Been researching a bit of AMD cpu's because my desire for Ryzen 3000 is growing daily. Found this interesting tidbit on CS:GO performance with Ryzen and the poor performance between CCX.

Yeah people have been talking about CCX being an issue since the beginning. I remember people were wondering if AMD would release a CPU without a CCX, just 4 cores alone but I don't think that ever happened
I do not recall if they planned on reducing latency of CCX for zen2
