AMD Zen 2 Deceitfulness

When an 3950X @750USD Lags Behind the I9 9900k @ 500 USD Released a Year Earlier & with 14nm , AMD fans will say the 3950X is not a gaming cpu , a productivity one with look at the CPU utilizations thing when they say min fps lagging. Forgetting the Old FX days ( High cores #  with luclaster per core performance behind the scenes) .

Old Song &  Dance .. Again & Again ..

Here Come AMD PreRelease Hype Train Slides that made many foaming hard.

PS:

I own an I9900k + Maximus Z390 Extreme XI + ... and a friend gifted me an R9 3900x +  X570 Aorus Xtreme ... Test by your self then drop the hype train.

Some Insight:

I9 9900k: October 2018
3950x: November 2019

I9 9900k: 14nm++++
3950x : 7nm

I9 9900k: 500 USD
3950x : 750 USD
Difference: 250 USD

I9 9900k : 5Ghz (Boost) 1st Two Cores , No IPC Increase
3950x :  4.7 Ghz (Boost) 1st Core , 25% IPC Increase

When AMD fails , AMD users will always say: it has another purpose

Each AMD release get many foaming and perceive Intel get doomed . Why do all the AMD fans feel the need to prove themselves?   Just get over it already AMD fans. Stop trying to justify your purchase.

Re: AMD Zen 2 Deceitfulness

Nice comparison and thanks for sharing.

NB:Totally unrelated but a friend gifted you an OLED LG 55 inch TV and a friend gifted you a 3950x? Can your friends be my friends ? :) (j/k)

I am my own friend, I gifted myself last year :)

Hehehe me too. But due to the current USD situation and the banks limits, I don't think i can gift myself this Christmas!

Re: AMD Zen 2 Deceitfulness

It's more like, you're trying to justify your purchase...

3950x is a 16 cores CPU in an AM4 socket.
9900k is a 8 cores CPU and microwave.

Why are you even comparing the price?
Single threaded performance is still obviously in Intel's favor... by a small margin of 10% and almost negligible on 1440p+, and no body denied that. If you're purely into gaming, and you don't do anything else at all with your desktop, and you care about that extra ~10fps then by all means go with Intel.
If you wanna compare that i9900k to an AMD CPU, you should do the comparison with 3600x-3700x CPUs.

Price to performance ratio is always in favor of AMD given the higher number of cores for a lower price. A friend bought a 2700x from the US for $130 3 days ago... do the math.

Also, if you want to look at the Threadripper CPU and Intel's competitor, enjoy some Linus videos:

Re: AMD Zen 2 Deceitfulness

While IPC is favoring Intel only on very high frequency, AMD is moving forward to take that place and in few months this minor IPC gap will be closed, meanwhile Intel has no response except adding an extra + to their dying 14++++++++ nm, I saw a news post on the web saying that Intel now is seeking Samsung help to be able to respond, the long awaited 10nm will be waited more and more

Re: AMD Zen 2 Deceitfulness

I am not being with Intel or AMD ,  I am a fan of max performance X or Y , A or B.

Nevertheless , What is the point of shrink the lithography while Zen 2 7nm still lags Intel 14 nm ++++ Coffe Lake Refresher ( based on aging skylake architecture ) in lightly and tightly threaded applications such as gaming ,  and when AMD in the premarketing slides said the 3950x has "effortless 1080p gaming that matches the i9 9900k" yet it fails now upon release. AMD paid a lot in R&D as a result they dropped the trend of " our cpu are for the masses" and moved to a new pricing schema with all Zen 2 .Yet with nwith a less tempting performance not matching expectations and pre marketing "hype" slides.

It is not all about a die shrink ,  it is about the engineering innovation. Intel mesh interconnect architecture is a multi-core system interconnect architecture that implements a synchronous, high-bandwidth, and scalable 2-dimensional array of half rings. in order to interconnect multiple physical cores together efficiently. This had proven successful from Skylake days and tuned untilq0 Coffelake Refreshers.

Prerelease marketing  slides and announcement get many foaming hard.

Let alone helming next gen console releases with Zen 2 based CPUs.

No need to rush ,  AMD with 7nm ( which in theory should be efficient enough to cross the 5ghz with a 25%  IPC boost and destoy Intel in everything still delivering underwhelming performance tier  ( for 7nm vs 14nm with a high pricing schema now.  What is  weired from AMD side is :

Their  low margin to OC out of the box ( on their advertised boost clocks) ?

Failing to hit their advertised boost clocks on multiplr cores  ( long debate of cpu internal triggers  and window scheduler)

Relatively high Vcore out of the box ( 1.29V)

This is at least with my 3900x and decent VRM board ,(X570 Aorus Xtreme)

Questions:

Is that what 7nm is all about ?

Does AMD released Zen2   by  sequzeeing every inch of their performance out of the box - to leverage their competition and compete more ? To match their prerelease marketing hype slides that set all of expectations?

Does lithography shrink alone creates the major performance gap or engineering inovation inside the cpu balance it and in some cases better( Intel Mesh architecture ).
