AMD Zen 3 (5000 Series), rumored 17% IPC gain.

17% uplift or go home AMD:D

mid be happy with 10% ipc and 200mhz clock speed. Because that's enough to dethrone Intel as the fastest gaming cpu

Zen 3 at all core 4.5ghz/4.6ghz and +10% IPC = Intel better start running for the hills because their "Intel is the best for gaming" shilling won't work anymore

'Hits' but does it keep on hitting for 4 hours? I want to believe I could buy a 3900X/3950X and fire up a CPU demanding game and the 3 or 4 cores running the game's most demanding workload (AI for example) would steam along at 4.6Ghz (I believe Windows scheduler assigns fastest cores to the most demanding tasks these days) making short work of the most CPU demanding tasks of the game and using the best resources available to remove any potential bottlenecks. What I suspect I'd get is one or two threads bouncing up to 4.6Ghz momentarily while doing little or no meaningful work while the other cores/threads would be chugging long at 4.1-4.2ghz. If that is genuinely not what we see now then I'm happy to be corrected but 'boost' speeds that don't exist in any meaningful way do AMD a disservice. A 17% IPC ST uplift would mean clock speed will become a moot point and I really want it to happen but I'd prefer a 17%IPC AND 10% clock speed uplift from Zen 3, its the only way to be sure!

My 3950x when stock will bounce around between 4.5ghz and 4.6ghz on 2 cores when doing single thread heavy workload. It is able to hold that clock speed range as long as temps are good. In Multithread it just drops everything down to 3.9ghz. I do more multi thread stuff so I just run all core 4.3ghz. I'd be happy with Zen 3 can give me all core 4.5/4.6ghz, with that extra IPC it will be the best at work and gaming

No probably not, I don't monitor it extensively to be fair so I can't say but they are definitely reaching advertised clocks was my point. I came from a Zen 1 1700 that wouldn't clock past 3.85Ghz so the performance boost was around 15% IPC plus ~15% clock boost so I was very happy with that.

I hope they can extract more IPC and clock like they promise but I will probably skip Zen3 and wait for Zen4 and a new socket anyway.
 
So annoying that by waiting for Zen 3 I’ll be on the last chipset before the new one with new memory tech...again.

Really want DDR5 but sick of waiting to upgrade.

3100x/3300x release I'm gonna guess. They mention it in regard to a filler part and something down the low end of the product stack (currently the 3600). Maybe mixed in with some new information on Zen 3 in regards to a chipset/socket restriction (AM4+ etc)

But they never said it would be compatible.

They fulfilled their promise through to 2020.

I'll get the video where they say this.

edit:

Here it is. Note they start discussing 3000 series being supported. Then move onto talking about AM5. Listen for a few minutes.

"Third Gen Ryzen is launching and that will obviously it will go into 2020, and there it is, that's AMD making good on that promise we made 3 years ago".

Sounds like zen 3 should be supported for down to x370 as well, as long as the mobo vendors make the update.

No, they are talking about Ryzen 3rd gen. The 3000 chips. Not Zen 3.

There is no guarantee Zen 3 is supported on AM4. That's the point I was making.

With Zen 2 (Ryzen 3000 chips) they fulfilled their promise. They are now free to do whatever they want.

If anyone has assumed that Zen 3 will be supported by current AM4 board, then that has been pure speculation.

They sorta make it sound like as long as the socket doesn't change it will be supported. Maybe that's just how i'm interpreting what they're saying.

He does say it would require something big to change for them not to support it. Something requiring a pin count change or the data pins on the processor changing.

But he doesn't rule out that it can happen next release. For example, he refuses to say whether DDR5 could be the trigger, he just says it could be.

Fingers crossed :)
 
I just watched a very disturbing video shared by BuildZoid.

it features benchmarks of a 9900k at 5ghz on water cooling vs a 3800x at 5ghz on LN2. Both system using 3733mhz cl14 memory with tuned timings.

Cinebench looked promising it the 3800x demolishing the 9900k by scoring 575 single core points to the 9900k's 520.

But that's where the wins stopped, despite the big advantage the 3800x has it still lost to the 9900k in games... this should not have happened

This tells me that if all zen 3 has is higher clocks and higher ipc it won't do anything for gaming, we have a bottleneck somewhere else. What that bottleneck is I don't know but Im willing to beat it's the high memory latency on zen 2.

Hopefully AMD has found a way to fix this bottleneck so that the extra clocks and ipc actually improve gaming performance cause on zen 2 it does very little - the 3800x gaming performance from stock to all core 5ghz only improved by 5%
