Topic: When will the Bitmain L4 miner come out? (Read 991 times)

14nm vs 16nm is for most purposes nothing more than terminology.

 The actual PERFORMANCE of the nodes is pretty much identical - variations on EACH show a wider range of performance difference than the variations between the two.

 I also don't buy into the theory that the TSMC "12nm" process is really 12nm - even TSMC calls it an "upgrade to their 16nm process" NOT a new process node with smaller feature size - which just raises questions as to what the ACTUAL feature size on their "in the works" 7nm node are going to actually be.

 ANOTHER of the reasons I'm not buying fully into the "7nm" hype is that it's been pretty widely reported that most of the folks that have announced "7nm" (TSMC and GF in specific) are not really going to a true 7nm gate size, they're going to end up very close on ACTUAL feature size to Intel's "10nm" process.

 Samsung MIGHT be an outlier there, they've been keeping details of their "7nm" work very close.

 The "new announced" more efficient miner I'll have to see in action before I believe the announced specs - but it's certainly not impossible, BitFury was showing the capability to hit that performance level with THEIR current chip if you ran it at a low enough voltage.
 Bitmain current chip IN THEORY could get close to that announced efficiency level as well, but they apparently had too many "variation in performance" issues when they tried on the early S9 batches, so they backed off some on pushing lower volts for better efficiency in the name of better reliability.


 The last time Bitmain did the "3 units ganged together" thing was the S5+ - which was NOT a rack-mount miner that they reserve their even-number models for.
 The S5+ in retrospect also seems to have been the initial experiment with their current "heat sink on the chip" type design that they used in the S7 and later.

Not to pile on too much, in one of the other threads, mention was made of a new BTC miner using a 14nm process and the performance was almost identical to BM's S9 with 16nm chips. The only apparent gain was a 20% decrease in power consumption.

and bitmain will generate only a new Version if they think they can a lot of money with that, currently the LTC is quite high and still a lot of units coming online...

A L4 is going to be nothing more than 2-3 L3+'s jammed together. Barring a major investment from Intel, you aren't getting smaller chips.

People are used to the idea of a new generation of miners showing up every 6 months to a year (in Bitcoin, in Scrypt it was more like every OTHER year even when they weren't caught up to semi state of the art).

 Too many of them don't understand why that *CAN'T* continue any more.

Its strange that people just assume new miners are going to come out left and right when there is zero evidence or information that would even make a sane person assume that was the case.

There almost definitely won't be a "L4" model - Bitmain reserved the even numbers for big rackmount-type miners that they haven't done at ALL for years.

 L5 - won't happen 'till a new semiconductor process node becomes available for a significant efficiency gain, be it called "10nm" (Intel) or "7nm" (pretty much everyone else).

 The days of miner manufacturers doing a new, much more efficient miner model whenever they choose to spend the money are OVER - they ended when Bitmain released the S9 ON THE CURRENT STATE OF THE ART SEMICONDUCTOR PROCESS NODE.

Here? No, this is Bitcoin only section.  Ask this in the altcoin section. 

Hi.
Does anyone know when the L4 will come out?

I've never boughten any miner before, so can anyone tell me if it will be worth it to buy an L3 or L4 when it comes out?
Ive heard they can get some real good profits. But can I have any feedback from here
