Intel Kaby Lake Refresh: The up gunned CPU Refresh... More cores = more performance?

Intel has leaked even more specs and details for the new line of CPUs that are set to appear at this final quarter of 2017 as well as a couple of confirmed Laptop ULV (Ultra Low Voltage) CPUs to the market.

Desktop

Starting with the Desktop CPUs. We'll definitely expect a HyperThreaded CPU in this line as its consumer flagship. As far as leaks go, it'll be a 6 Core CPU, with 12 threads. This will place it pretty much along the lines of examples like the X99 LGA 2011 based CPUs like the i7 5820K, and its successors the i7 6800K and 6850K SKUs. With the K suffix, we should expect nice gains from overclocks. Personally as far as the flagship X Series CPUs go, I judge the 6800 series as running real hot and requires some High End coolers to handle this TDP. But because of the efficiency of Kaby Lake which we should expect abit more for this one, I really hope this will become less of an issue.

But down the mainstream and cheaper line, things start to get plenty interesting. The i5s should get a Hex Core non-Hyperthreaded which is a really heavy boost compared to a Quad Core. It'll probably give performance that is almost as comparable as the old i7s. For i3s details are even juicier. The 8350K is specced as a Quad Core. As far as rumours about HyperThreading go, it might have it, it might not. Regardless of the case, I actually really am intrigued and interested on finding out its performance and heck, I wouldn't even mind if it doesn't have hyper threading. If 4 cores on an i3 remains true, that would be really nice and can bash the Ryzen 3 and 5s. All eyes on the i3s at least because this is gonna be interesting if even a non-Hyperthreaded Quad Core delivers the goods expected of it.

PROS: Big Competition on the budget side. True 4 core and 6 Core CPUs
CONS: Suspect high price.

Laptop

We have confirmed specs of their new ULV Laptop SKUs which just recently launched.

Core i7 8650U (4C8T, 6MB Cache)
Core i7 8550U (4C8T, 6MB Cache)
Core i5 8350U (4C8T, 4MB Cache)
Core i5 8250U (4C8T, 4MB Cache)

Compared to all the other Ultra Low Voltage Laptop chips prior to this, these two chips remains as true Quad Cores with Hyper Threading as we usually regard i7s as. The last generation was stuck with 2 Cores on the i7 7600U and 7500U so should be a big upgrade. Sure, base clock speeds will be lower in turn, but I reckon their Multi Threaded performance will definitely thrash some of the Quad Core i5 that popped up since Skylake. The 8650 and 8550 are specced at 15 Watts but can boost to 25 Watts TDP if required. The 8650U has a 1.9 GHz base to 4.2 GHz Turbo for a single core, which should give more than adequate Single threaded performance and the 8550U at 1.8 to 4.0. Also the other big difference with this Kaby Refresh, is doubling the Cache from 4MB to 8MB.

That should effectively increase the performance of ULV i7s by as much as 40-50% over their predecessors, especially their Multi-Threaded performance. Sure it won't be the regular 35W TDP cousins, but compare that with say the Quad Core i5 6300HQ, 6440HQ, 7300HQ and 7440HQ, for less TDP and with more Cores, should match the i5s at a respective level. It remains to be seen about the true performance of these Quad Cores, especially the i5 8350U and 8250U when it comes out.

The improvements don't stop there, the i5 Refresh do carry this Quad Core WITH hyperthreading trend. And it runs pretty well. Notebookcheck (German Region) did a review of the Acer Swift 3 that comes with an i5 8250U, and it matches up well with the i5 7300HQ, edging out the latter in both the Single and the Multi-Threaded scores on Cinebench.

SMRT and the MRT Breakdowns: Get your act together, this is 2017.

I refer to the following article in light of the recent MRT incidents and stuff that I really should write in this blog of Paul's Tech Insights.

http://www.jeraldinephneah.com/singapore-mrt-breakdown/

It's not Computer Related, but in a way still Tech because of the systems involved in this government operated transport system. This is such a well written article questioning the reliability of the SMRT transport system. What the writer wrote got it absolutely spot-on.

 For myself, the plus side is I like taking the train, I like the system itself; I think it's pretty damn awesome but never like the breakdowns and the recent frequencies that it does.

After a few years of constant breakdowns and disruptions, it is time for SMRT to have a huge reality check. After all the price hikes and us commuters have to fork, we expect any bugs to be mostly ironed out, reliability back to where it should be. There's no excuse to leave themselves in denial of all this.

 For many, especially for #2 point Jeraldine highlighted, the MRT just can't afford to break down on people that doesn't have any other transport option whether the bus stop is so ulu, or change here change there on the bus....The public is just so dependant and needs to rely on it to run safely and fuss free as much as possible.

C'mon, it's 2017 now, and the system is well over 35 years old. And so many incidents of breakdowns and by now surely sensible protocols should have been thought up by now to avoid breakdown issues or accident issues.

This morning's breakdown was significant because it was taking place on an Exam day. The thing is MOE took SO LONG to post their reassurances that no penalties will be taken against them. And SMRT took SO LONG to deploy measures and stuff. Clearly, never learning from their past breakdowns and there's no more excuses anymore that just leave a bad taste in everybody's mouths. And from all the photos whenever a train breaks, SMRT's Crowd Control SUCKS, tell ya plain.

You know whenever you play for a concert or gig and it acts like a rehearsal to make the next one better. Every breakdown is a rehearsal for the following but not only it didn't improve, it just got worse.

But what about those without Facebook I wonder?
And what about the students too man? Entering the state of increasing Kanchiong-ness if you will when, the train breaks on a pivotal date. Who would want to take the exam in a mental state like this?
And what about logistics for both invigilators and students alike? 

Think about that. Any responsibilities from their affected results lies completely with SMRT because MOE within their capacity to be fair, cannot do anything about transport issues, cause' they ain't the root cause of the disruption chain.

No student should ever have to go through such an ordeal.

Speaking of accidents, look at the recent LRT incident where a man, I know drunk but then still..., got ran over not once, but twice. Whatever safety measures there is pretty much non-existent and no plans down the pipeline to make this line safer for commuters. Ridiculous! Furthermore, Not long ago, two workers got slammed by the MRT earlier. I don't see why in 2017, things like this still happen.

SMRT, you better get your act together. I wanna emphasise again, this is 2017, we should look towards much higher reliability in terms of way less or even no more breakdowns especially in the thick of moments. And less accidents, please. We also don't want any waste of life caused by safety lapses, do we?

Some help for trading (Singapore Only!) towards the ITX build that I held off for so long.

Heya all, I need some help with trading stuff or buy these parts from me. For a long time I've been holding off my ITX build for so long because I just don't have the budget. Now that I do, but also need to do a complete cleanup of so many parts here and there that now I need to do some consolidating here.

The ITX build although it was working under Ben, the Power Supply wasn't really doing much good till it died. Changing the Power Supply would do wonders there. So here is the parts that are certainly working.

MSI Z87I Board
Coolermaster Elite 120
Drives
RAM

And here is all this crap that I'm trying to sell or trade.
Look at all this stuff.


Quite a whole butt load of parts that I'm trying to sell for updated parts, if you guys can help me that'll be great!

Here's what I have there:

Graphics Cards
GTX 970: MSI Armor Edition
GTX 970: Palit Vanilla Edition.
Quadro 600
Radeon R9 290
Radeon 6950 (For parts, may not be working)
Radeon 5850 (Still works quite well there!)

CPUs:
Intel Core i7 2600K - LGA1155 4C8T
Intel Xeon W3565 - LGA1366 4C8T
Intel Core i3 4330 - LGA 1150 2C4T
Intel Core i3 2100 - LGA 1155 2C4T
Pentium G3258 - LGA1150 2C2T

Sounds quite a lot right?

What I am looking for are the following:
Core i7 4790K with a decent Low Profile Cooler
16GB in 2x8 if possible
GTX 1070.
650W PSU

So yup, some help to get my ITX build up and running would be great!
