Hi guys, my 1st post here but i had to sign up and ask a question if i may ?

There is clearly a lot of well informed guys here so my thinking is who better to ask so..

Talking from the POV of a desktop cpu for a HTPC and on chip gpu, doesn't it seem strange that the broadwell has GT4e @ 128mb cache in that the new skylake will only have GT4e @ 64mb and again with kaby lake, although i do see a mobile there with GT4e & 2x 128mb it's not desktop, it looks like a step backwards to me, to top it off it's over two upcoming chips with nothing matching the broadwell igpu.

Am i missing something here?

Well, Skylake does have DDR4 memory support. The faster DRAM should help the performance of the memory subsystem, and reduce the need for the eDRAM cache.

But also, I suspect that they are running against the limitation of what they can physically fit on the package. If Skylake is a bigger chip than Broadwell, they may need to use a smaller eDRAM chip to fit both of them under the heat spreader.

Big news, but let's take it with a grain of salt:

Intel Ditching Cannonlake In Favor of Ice Lake, FVIR Is History For Skylake and Kabylake


I don't see anything new in this news. Also there is nothing about "Ditching Cannonlake In Favor of Ice Lake" in their source.

So you think they made it up?

Hardwareluxx (the source) implies Ice Lake succeeds Kaby Lake (desktops):

Now, FIVR seems to be history for the upcoming "Skylake" and "Kaby Lake" processors, as Intel plans to release the two upcoming CPU generations without it. However, "Ice Lake" as the generation after next is codenamed, will then one again use a FIVR.

Hmmm ye the DDR4, true i never thought of that, thx buddy.

Looks like we might see a lot of IGPU tests between the BW & the Future SL & KL cpu's interesting to see which is better of course given that all clock speeds are equal DDR4 w/64mb of eDRAM vs more eDRAM (128MB+).

Welcome. Just like NTMBK said, I vote for die/package size limitation. That's probably the reason why Haswell Iris Pro didn't make it to LGA1150, 14nm finally allows it.

They don't say Cannonlake is cancelled, so I think they are just confused with Kabylake. On desktop Cannonlake might be dead like Broadwell but this is nothing new.

Congrats -- that's a great chip. What did you upgrade from?

Thanks . I upgraded from Athlon 750K and radeon 6870. Got 4690K,pretty good perf. jump imo and GTX960 -more than 2x faster than old radeon.

I assembled the build and I'm pleased so far. Had no time to test it much, it booted fine in BIOS and board has plethora of options for tweaking. I use stock cooler for now -it's ok for the purpose but I will be buying WC along with a new case next month. I'm done with upgrading for at least 2 or 3 years. My old Athlon (PD based) served me well for more than 2 years now, it was time to upgrade.

I now see that i5 6500 will supposedly be below 200$ which is a nice price for that chip, but it won't come that soon on the market and I already got a chip that with board will cost approx. the same (counting in the initial price gouging by retailers).

In this Roadmap Broadwell-E still exists. Roadmap publish date obviously something between April-June.

Broadwell-EP/EX was also still on the cards in that presentation from late May. If they dumped big Broadwell it must be a very recent decision, no surprise here.

Some interesting points:

- Higher clocked Haswell-E parts this quarter.
- Higher clocked Broadwell-K parts in Q4-2015.
- Core i7 6700, Core i5 6600 and Core i5 6500 still launching this quarter (likely September).
- Full Core i3 and Pentium/Celeron Skylake-S lineup in Q4-2015.
- Higher clocked Skylake-S parts in Q1-2016.

That's awesome

The machine I'm writing this on is an i5 4590 (w/ H81 board) + GeForce GTX 960 and it's a joy to use.

Where do you see that..?

Its normal yes. It usually means a faster bin. With the reservation not to. Been so last 10 years or more.

Microsoft has now finalized Windows 10, ready for its release later this month. Sources familiar with Microsoft's plans tell The Verge that the software giant has selected build 10240 as the final release to manufacturing (RTM) copy, allowing PC makers to start loading the software onto new machines ready for release. We understand that Microsoft is signing off on the build internally today, and may announce the RTM publicly by the end of the week or choose to ignore the milestone and focus on the launch. While Microsoft is planning to launch Windows 10 on July 29th, new PCs with the software won’t be available until some weeks later.

Windows 10 RTM ready, but likely no Windows 10 PCs until some weeks after July 29th.
Just in time for Skylake? I can imagine OEMs updating some of the existing Haswell/Broadwell stuff to the new OS but they might be waiting Skylake to release the cool & new design wins.

Carrizo probably was affected by OEM's wait for Windows 10 too and now it will face mobile Skylake. Not that it would have many design wins otherwise anyway.

I'm seeing a new i3 class in there, t3 for skylake, maybe an unlocked cpu? Before anyone says there's no -k there the unlocked Pentium hasn't it too... one can dream

Or the Iris Pro i3

But an unlocked i3 isnt impossible to imagine after the Pentium.

Shh, don't scare AMD.


Intel Surges 8%: Q2 Revenue, EPS Beat; Q3 Rev View ; Trims Year View
By Tiernan Ray
Chip giant Intel (INTC) this afternoon reported Q2 revenue and earnings that topped analysts’ expectations, and beat with its Q3 revenue view as well, and trimmed its year outlook. The shares surged in late trading.

Revenue in the three months ended in June rose to $13.2 billion, yielding EPS of 55 cents.
Analysts had been modeling $13 billion and 50 cents per share.

Intel’s revenue from its “client computing group” dropped 14%, while its “data center group,” which sells server chips, saw a 10% jump.

CEO Brian Krzanich said the results “demonstrate the transformation of our business,” and that the company expects the debut of its new “Skylake” chip later in the year, and the roll-out of Microsoft’s Windows 10, will “bring excitement to client computing.”

For the current quarter, the company sees revenue of 13.8 billion to $14.8 billion, which, at the midpoint, is above consensus for $14.06 billion.

For the full year, the company trimmed its outlook, with revenue expected down 1%, versus a view back in April for revenue to be flat. That is still better than the consensus for a 2% decline this year.

Intel stock is up $2.35, or almost 8%, in late trading.
