1900x vs 1800x

[Tim613]

AMD Ryzen Threadripper 1900X	8/16	32 MB	180 W	3.8 GHz	4.0 Ghz	Yes	$549
AMD Ryzen 7 1800X	8/16	16 MB	95 W	3.6 GHz	4.0 GHz	Yes	$499
AMD Ryzen 7 1700X	8/16	16 MB	95 W	3.4 GHz	3.8 GHz	Yes	$399
AMD Ryzen 7 1700	8/16	16 MB	65 W	3.0 GHz	3.7 GHz	Yes	$329

 

does anyone think there will be much perfomance difference between them? gaming or multitasking? i would assume that the 1900x wouldn't use a game mode as well? how will the 2 active dies split the 8 cores?

I expect some differences due to the number of memory channels, the amount of cache, and the additional intercommunication needed (notice these things go in different directions). Also clocks could be a bit better. Ultimately, I don't think any of these things could lead to a performance difference that justifies the motherboard price premium you will have to pay for X399. Hence, I think the 1900X would only make sense if you really need the X399 features (like memory bandwidth having a huge impact in your use case, or many PCIe lanes needed).

 

PS: notice all the "expect", "believe", "think", etc in my post - conjecture mode enabled

I think gaming performance will be much worse on the 1900x. 

The 1900x is basically two highest binned 1500x dies on one PCB. The interconnection latency between the two dies are killing the gaming performance. (if you get the game running at all ffs)

 

We actually already see this with the 1950x which lacks behind the 1800x even if you use the "gaming mode" which deactivates one die including RAM completly...

They wont do that, it will be a single die. If its not, the 1900x is dead.

but they are. gaming mode will be a 1500x. this cpu is really pointless..... it does not appeal to the hardcore benchmarkers or the hedt platform. at least its better than the 7740x and 7640x....

no one has the 1900x yet?

I disagree. I mean, I agree it won't appeal to gamers or benchmarkers. I also think that producing CPUs for a handful of money-wasting gamers or benchmarkers is what's pointless  

 

The 1900 is simply meant for people who can use 64 PCIe lanes and/or quad-channel RAM, but are fine with 8 cores - sometimes they are even license-limited to 8 cores on the software side. Same reason why there's an 8-core Epyc server CPU.

 

Gamers naturally won't see the point in paying more for features they don't need, but pointless for gamers doesn't equate pointless in general.

I don't think you can have quad channel and all the lanes by using only one die, which would make the 1900x an 1800x on a more expensive platform - kind of Kaby Lake-X nonsense. So I'd say that if they do use a single die, then 1900x is dead.

No I don´t think anyone has it yet. It will come later in August if I remember correctly

This is correct it cant have quad channel if its not two dies.

Well makes no sense to release it on TR4 then. Without two die design there will be no quad channel and less pci-e lanes. Its just made for "miners" LOL

Interesting to note for sure!

 

I was considering the 1900x mostly as an intro cpu to get into the TR4 platform.

 

I figured it would have been a highly binned 1800x slapped onto a tr4 die, guess not.

 

Great information here for sure!

the 1950x are two highly binned 1800x dies on one PCB ^^

1920x are two highly binned 1600x dies on one PCB

1900x will be two highly binned 1500x dies on one PCB

Well there go my THREADRIPPER dreams lol

 

Rather just build a ryzen 1700 and OC it up then.

yepp, same for me either r71700 with very high speed RAM (3600) or  i7 8700k.

sounds like what im gonna do too or wait to see how coffee lake is, i already pre ordered a x399 board so it looks like i may have to return it lol

Tbh, if coffee lake dishes out an affordable i7 6core not on x299...I'd look into that.

so i should look for xeon on ebay? cheaper and better than ryzen?

[Tim613]

looks like it just listed in india from this article https://www.techpowerup.com/236531/amd-ryzen-threadripper-1900x-starts-selling-in-india and it had to say this about it "the 8-core/16-thread Threadripper 1900X features 16 MB of L3 cache, as opposed to 32 MB on the 1920X and 1950X. This could mean that AMD is configuring the two "Summit Ridge" dies on the 1900X in a 2+2+2+2 CCX configuration, with 4 MB of L3 cache per CCX, just like on the Ryzen 5 1400."

 

so what would that mean for the perfomance?
