9900KFC with possible edram

might be worth the upgrade to this given fact that most laptop can't take advantage of high clocks due to heat, and especially more for clevo since it can't use iGP anyway.

problem is if there will be binned chips sold or will it end with just 9900k from SL/caseking.

 

Finger-lickin' good.

 

K, ok we know means unlocked. F is kind of new no? meaning no integrated graphics, or most likely cpus that have defective integrated graphics which in the past would be discarded, but in this day of age with extreme shortage of intel 14nm chips have become a viable commercial product. The C referring to the extra eDRAM, no? Which purpose is to increase the performance of the integrated graphics, no? which according to the F nomenclature is disabled?
Damn, Intel better get that 10nm mass production going......

 

haha im loving it (McD pun intended )!

 

Maybe the eDRAM can be used as a really fast cache? Just wondering.

 

Yes

On the 5775C it greatly reduces latency in repeatedly used datasets between the size of L3 cache (6Mb in those 4 core Broadwells) and the L4 size of 128Mb. The Userbenchmark latency chart shows this nicely.

That (and better IMC/SA) improved IPC over Haswell, decently in some cases by 10-15% in games for example

If dual channel ringbus is holding the 9900K chip back, it may help, but I'm not seeing any evidence of that. The difference between 2133 and 4000mhz DDR4 on 9900K is ~10% at CPU-bottleneck low res tests, dropping to 1-2% at 4K.

Also, many of those IMC and System agent improvements were implemented in Skylake.

The edram was on a separate chip under the IHS so shouldn't require a new die, only a CPU PCB.

But the recent leak of 9th gen mobile chips in an Intel document didn't show a KFC flavour of 9900, only K and KF
(actually, I wonder if it showed 9900T? Hmm will check that)

I think it was a typo in the aida64 changelog, after all C is next to F on a standard US keyboard...

 

that 128mb edram would be so worth buying for many of the cpu tasks considering this laptop is already a dead end just like many other intel laptops dies after 1-2yrs.

for actual benefits in terms of improvements will be based of software used and actual testing
