AMD Zen 2 Architecture: Socket AM4, 2019, Code-named "Matisse"

[R-T-B]

Right.. which we are saying isn't relevant. Just as Huffy makes a bike that goes 50 MPH, that doesn't mean ALL bikes made by Huffy go 50 MPH... which is, seemingly, the point he keeps harping on. There are too many differences in uarch and other things which make that point, well, utterly useless.

The whole thing started with birdies troll comment on Intel being the only 5 GHz node, you realize.

It looks like you all got trolled into a pointless debate.

Ha, lol, I don't see his posts unless I click to view...

For balance, don't forget the fact that Intel still on an old architecture, e.g. no nvme direct channel into CPU as with Ryzen AM4. All those pci lanes and any devices other than graphics card on Z370 have to share a DMI pcie x4 link from the chipset. Check out the block diagrams

 

[EarthDog]

Some boards are actually CPU connected for Intel... I think on the X299 platform.. not sure about Z270...

 

[Frick]

Thing is , I don't want them to start a clock speed race again.

"I thought this was an enthusaists forum."

Someone had to say it.

Personally I find it interesting how ok it has suddenly become with insane TDPs and power draws in consumer chips. Things are moving on the high end as well!

 

[Lynton]

@EarthDog only HEDT x99/299 as you say on the Intel side connect pcie lanes direct to cpu. nothing on mainstream does this from the blue team

 

[EarthDog]

Yep.

Now give me a holler when that matters to the masses it hasnt found its way to intel mainstream. We'll chat again in a couple years.

I think his only real point is that GloFo has a process capable of doing higher clocks than the lpp Zen is using today.

I too believe that the LPP is holding Zen back.

I think Zen is held back by the current node but to what extent it's hard to say. Claiming it will hit X Ghz guaranteed it's nothing more than a supposition.

But you gained a lot of performance in the process too. OK so yeah chips can draw up to 2-3 times more power that the ones from a decade ago but they are also significantly faster. I'm fine with that tradeoff.

It will be exciting to see Zen's performance with better clocks. It scales so well with Mhz at the moment.

As much as people hate Intel, they are currently the only company in the semiconductor industry which can churn out high speed (as in high frequency) 14nm chips, soon to be followed by 10nm.

I wouldn't call 15 mo minimum soon given how 10nm has been playing out for them
And really, that's probably many months more generous than reality given that mobile parts will likely not make it till the end of next year.

Curious... how can you tell that when it 'overclocks' 400 mhz?

 

[Xajel]

You mean at least 5GHz

There's no exact official TDP number for the Z14 PU, but a rough calculation put each Z13 PU (previous gen.) at about 180~200W...

There is a couple of other articles about it - that the overclock also brings speed bumps to other parts of the chip (not just the core) which helps to lower the cache latency of the chip - and when you combine OC+Memory OC that 400Mhz brings a huge increase in performance. My 1800x went from 1650 cb to 1830 cb going from 3.7 to 3.95 w/ 3200mhz ram and some bios tweaks.

Ryzen seems a bit bottle necked - if refinement of the cache latency and higher clocks can alleviate some of those constraints it will be a really competitive product.

 

[EarthDog]

Yes, using faster memory helps those CPUs quite a bit in gaming. Part of that result is also it being a few % slower in general (IPC) with more headroom to grow vs Intel chips closer to the performance ceiling already being clocked higher stock and better IPC.

As far as your CB results, that is about right for 300 Mhz and increased memory speeds, maybe low, actually.

EDIT: Depends on the title too... Here is one that just came out at Anand...

I guess I'm not entirely sure I can buy into that as a blanket statement, especially without a comparison saying its better than others.

Anyone else heard anything beforehand about the new chipsets?

Their corresponding chipsets, the 400 series, will also become available in March 2018 with X470- or B450-based motherboards to be the first to hit the store shelves. The chipsets are still designed by ASMedia and its orders for the chipsets are expected to grow dramatically starting January 2018.

Yet another low power optimized node doesn't sound great to me. And I sure as hell hope they don't start doing that chipset after chipset crap Intel is doing.
