AMD ZEN 2 7nm CPUs on Track

Not to diverge too much from topic, but I assume you're partially referring to the mem compatibility issues that plagued Ryzen 1 and it's chipsets? If so, do you know if those issues lied in the chipset or the CPU? Reason I ask is two-fold: if the memory compatibility issues is with the chipset, this largely invalidates the advantage of AM4 handling multiple gens of CPUs if you need to upgrade chipset to avoid issues; 2) I am doing a Ryzen 2600 + x370 build this weekend (and JHC, I had a helluva time getting my 1st Ryzen platform working due to memory issues)

It's all in the bios, bios fixed the issues and B350 boards even A320's can run good memory timings.

I'm super excited about Ryzen but I want to wait for Gen 3 in 2019. Hoping for the same clock for clock performance as intel at a much reduced price.

Saw the 2700x was almost as fast as the 8700K but at the same cost. For me, doesn't make sense to buy Ryzen just yet.

However, if they can get the Gen 3 Ryzen to say, 10 or 12 cores and 4.5+ Ghz on all cores at 20% to 25% cheaper than Intel @ the same exact performance or better, then I will make the move. And, it could happen.

I'm going to assume the 9700K is gonna stomp all over AMD.

I love competition!

Gen 3 Ryzen is gen 2 Zen. We are talking about Ryzen 3, due in 2019, here. I always find it confusing when they have different numbering for Ryzen and Zen. Gen 2 Ryzen is actually Zen refresh or Zen+. So hopefully Ryzen 3 can be a massive performance leap and dominate Intel, 7nm should help.

Well at least they are keeping the update pace they said they would.

My bad. I forgot the topic of the thread. I was thinking about client desktops and latops at non tech firsm when I wrote that. Datacenter execs certainly would be more informed. But he did say it was not a tech company

I clearly assumed you were talking about buying an EPYC system for home use /s

Please AMD, no 3-5% “improvements” like your competition. You have seen what that strategy has done to Intel over the last 12 years or so. You were nearly bankrupted due to your own incompetence, I hope you have learned your lessons.... The gain from Zen+ will be very telling of your capabilities and what lies in your future.

Do you think its super easy to just pull 10%+ IPC improvements without a massive redesign?

AMD may have another 10% this time, but I don't think we will see that past this release. They are going to rely on clockspeed, which is all they need since they match Intel now with a fairly large clock speed deficit.

The 2700x is very good compared to intel lately, I think this will be another "big bang" if you will... Hoping AMD may have an "intel buster" in the next year or so.

3-5% improvements generation over generation are perfectly fine.

Keep in mind, it is infinitely more technically challenging to increase performance today than it was 10-15 years ago when there was last competition between the two.

What many people don't talk about with Intel's rather small generation to generation performance improvements over the last 10-15 years is that, sure, the 3-5% improvements were small for each gen, but their tick-tock approach lead to rather rapid generation updates. Individually these 3-5% improvements are rather small, but they behave much like compound interest, and once added on top of one and other turn into something more substantial.


If we just assume an average of 4% per gen:



Now, agreed, this is not as fast as it was during the height of CPU advancement, but as previously discussed, CPU advancement is much more difficult today with current node sizes than it once was, and it's only going to get more and more difficult.

Don't get me wrong. I am curious about Epyc in part because my server in my basement could use an upgrade, but more because I look at Epyc as some evidence of what might come next in the consumer space.

Sometimes I get confused as to which thread I am in

I'm sure there will be growing pains for both sides when the switch to ddr5/pcie 4.0 happens. But since the cats out of the bag for ryzen amd doesnt have to really worry about being ultra secretive about it like they were for first gen ryzen.

I think the issue came down to AMD taking up as much processing capacity for CPU’s to ensure stock.

Honestly if they do that it ain't going to be 20-25% cheaper. Heck for once amd deserve the money. Pay the man if they deliver you what you want. I would happily pay 399.99 for a 10-12 core chip that will do 4.5ghz if that is 2700x replacement. But I think you will likely see amd stick to 8 core for now. I don't see much need for 10-12 cores for the mainstream chips they are targeting. They will leave more cores to epyc. I am sure you will see more core speed though.

I agree with pay the man. I’ve enjoyed going back to AMD again, reminds me of the old days moving to the competition. I only have one intel system running now and it’s a celeron media PC lol.

This is not about strategy. It is about being bound by physical laws. SS OoO designs have hit an IPC wall.

Personally I am expecting ~7% IPC gains for Zen2.
