my motherboard is ready.

I still haven't decided which one, but i'm guessing the 3700x @ msi x470 gaming pro carbon.
(I have a bad feeling about 3900x that it may suffer from latency issues - but again i haven't seen dies of 3700 model anyway.)
Yeah that's the thing. If it turns out that 8 cores on 1 chiplet via 3700x and 3800x, performs better for gaming vs 12 cores on 2 chiplets via 3900x, I may end up going for 8 cores only. Tripling my current core count would have been nice though. XD

Given that games need no more than six cores at most to top off performance, and need single-core performance at the same time for real games, the six core parts and twelve core parts that use two six core die should perform similarly. The eight core parts might be even slower due to heat on the one CPU die.

I do stress might- there're still unknowns surrounding what AMD got right and what they might not have.

This would be very interesting if true (6/12 being better than 8)

Although you mention the 6 core being need at most like its absolute fact. People kept saying that with i5's long after it wasn't the case.

Do you have any links to back that claim up. I am not really saying that it is wrong or right, would just love to see some conclusive data.

I'd link [H] reviews, but they're worth reviewing on their own, using a 7700K 4 / 8 part. Kyle did his own thread with an 8600K, which is a 6 / 6 part.

If you keep clockspeed steady on the architecture being compared, you find that if you strip a system down for benchmark runs your frametimes with four cores and eight threads are equivalent. Going up to six cores (SMT or no) gives you just enough overkill so that you don't have to worry (much) about the normal background stuff that your average enthusiast would be running in the background while gaming.

I haven't done proper testing like you mention with the same architecture. But I have seen my own system recently struggle with an i5 Haswell even at 4k. Swapping with a 6/12 5820k fixed the issue.

I would be curious to see a 6/6 compared to say a 6/12 or even 8/16 on all other things considered. I imagine someone has done that testing with some intel 9xxx chips.

My 2500k was dogging at 1440p60. The first upgrade I did was to a 6700k, a 4 / 8 part, and it ran significantly better. I've only upgraded it since then for the purpose of entertaining other workloads.

Plenty have, and there are gains to be seen depending on application and type of game, but with respect to real-time responsiveness, largely when measured with frametimes (not framerates!), the difference is in the noise, that I've seen.

If performance is to my liking I may side grade to an 8 core with an ASRock motherboard for the TB3 ports with an eye on shifting to 16 cores next year. If not I may just drop an 8 core into my z370.

8 Core cpus will be the new sweet spot as far as gaming goes I'm thinking. Right now Intel and AMD are increasing core counts faster than game devs can adapt.

That's where I'm at. It's hard to recommend anything other than an R7 2700 / R7 2700X today for most gaming uses. Exceptions would largely center around trying to keep frametimes down at high framerates (120Hz+), which I do, but I understand that that's far from a universal desire let alone requirement.

Looking at the Ryzen 3600 as a potential plex server baremetal build. Paired with an unlocked P400 for transcoding I'm pretty confident that'll serve quite well at 4k media duties(transcoding as needed).

Jim AdoredTV posted an interesting video on his Ryzen 3000 analysis which is think is pretty spot on. In summary, he thinks the chiplets on the Ryzen 9 will be better binned, therefore are clocked higher at lower TDP and may offer better gaming performance irrespective of core count. I tend to agree. I’m which case, if you want the best CPU for productivity and gaming, you’re better off with the Ryzen 9.

Looking forward to reviews. Going to be deciding between the 3700x and 3800x depending on how they do in games.
I am looking at these chips as well. Seeing that they are both X models there doesn't seem to be much difference between the two if we compare them to the naming scheme of Ryzen 2.

I see the TDP difference but assume that is out the window once OCing takes effect.

I really want to get zen2 but I will want something at or near 5ghz al core to make the switch unless ipc is just stupid fast. I run an 8086k @ 5ghz all core and really don’t need anything faster for what I do. But I would like to move back to and provided I gain some performance. Not looking to side grade.

I'm interested but waiting for reviews. It sounds like the MOBOs are going to be pretty spendy and I think this will be the last AM4 platform

I really want the 3700x i wish i could pre-order it or something. I'm dead convinced this is the chip for upgrading my workstation from a 2600 overclocked to 41.5Ghz. I could really use the extra 2 cores and 4 threads.

If you're running your 2600 at 41.5Ghz, you shouldn't be upgrading anything ;)

I read this is Doc Brown's voice.

Waiting for zen2 threadripper. 16c with ~400mhz higher speeds, 15% higher ipc and quad channel ram with minimum 180-200w to push through it sounds like the sweet spot to me.

Zen2 Threadripper, aka Threadripper 3, may very well debut with 24-core / 48-thread as the entry level...

3920X - 24C/48T
3950X - 32C/64T
3970WX - 48C/96T
3990WX - 64C/128T

It may, but if am4 tops out at 12 and we don't get the 16c before tr4 gen3, they'll start at 16c. They may overlap anyway, like they did with tr4 gen1.

It wont
AMD had completely redesigned the infinity fabric and all the flaws that were of the old have been eliminated. Zen 2 is not a refresh of zen 1. It's an entirely redesigned and improved arch. It Carrys over some of the core design etc but many many things have changed. Gaming shouldn't matter between 6 and 12 cores performance wise at all.

And now we can overclock the uncore portion as well as the processor cores.

Do you have a reference for the cores themselves being different?

My understanding is that Zen2 mostly just gets the uncore (etc) 'out of the way', where it was holding Zen / Zen+ back with stuff like being tied to memory clockspeed, being overly sensitive to memory latency, having excessive latency between CCXs and worse between dies, and having poor clock headroom.

If the independent benchmarks hold what AMD is selling, they'll have improved on all the other stuff, though they're still lacking in corespeed a bit.

No. You didn't. You said:



"Entirely redesigned" <> "slightly refined"

Just pointing out your own words to you. I got no dog in this fight.
Who in the hell cares?

Redesigned doesnt mean brand new. It means take what is already designed and redo it again while making changes. I never said brand new.

Stop being pedantic sigh

Intel has thrown down the gauntlet!...as it pertains to gaming performance, Intel issued an indirect challenge to AMD to "beat us in real-world gaming" if it wants to claim the performance crown..."So you’re going to hear a lot about gaming CPUs this week...They may or may not come from certain three letter acronyms...That said, here’s what I want to challenge you...I want to challenge you to challenge them...If they want this crown come beat us in real world gaming, real world gaming should be the defining criteria that we use to assess the world’s best gaming CPU," Jon Carvill, Intel's VP of marketing, told PCGamesN..."I challenge you to challenge anyone that wants to compete for this crown to come meet us in real world gaming. That’s the measure that we’re going to stand by."...
