HDMI is typically, what, 1-2m

bwDraco

HDMI 2.1 cables are not going to be cheap.

Michael Frank

> Q: When will the HDMI 2.1 Compliance Test Specification be available?

A: The HDMI 2.1 Compliance Test Specification (CTS) will be published in Q2-Q3 2017.

I guess we won't know the max length until then?

Bob

cat7a is supposedly able to do 40gbit at 50m and 100gbit at 15m...

@bwDraco meh. as always, depends where you buy em

bwDraco

They're going to have to be STP cables, for starters (you could get away with UTP cables with earlier versions of HDMI).

Michael Frank

Oh... you need to register as an HDMI adopter to get the HDMI 2.1 spec sheet :(

bwDraco

12:04 AM

Dec 7 '15 at 19:45, by bwDraco

We're coming to a point where ordinary, low-cost copper cabling is going to be inadequate for cable runs of more than a few feet.

Michael Frank

HDMI can(could?) currently sustain full bandwidth up to 10 metres. So not quite at that point.

bwDraco

Again, highly dependent on cable quality at this point.

Michael Frank

There probably won't be a defined maximum length. All serious cable makers will be sending their cables in for certification anyway.

Bob

still kinda meh

displayport can do, what, 25gbit over 4 lanes

with a defined max of 5m but a more practical max of 3m

bwDraco

> practical max of 3m

That's going to be an issue with double the bandwidth.

UTP cables will not cut it.

Dog

12:09 AM

So Dell lied about their thunderbolt laptops...

Bob

9 mins ago, by Bob

HDMI is typically, what, 1-2m

bwDraco

There are home theater applications that require longer cable runs than this.

Bob

we're not talking cross-house or even cross-room runs here, y'know

bwDraco

In some cases, up to 10m, in fact.

Bob

if you're doing longer runs, then you do something else. pay more.

doesn't mean shorter but still useful lengths are impossible

Dog

12:11 AM

@Bob Chances are the vast majority of cable runs are less than that

Bob

@Dog yup

5m was the max certifiable, and 3m was just a 'common and not too expensive' number

Michael Frank

@Dog About what?

Bob

2m is the longest most people would need. 1m would work for many cases

Dog

I'd say like, >90% of people use HDMI or DP to connect a PC to a monitor or console to a TV, etc.

bwDraco

Well, none of our HDMI cables are more than 2m long, but I can see how a generic cable, even just 2m long, will have trouble carrying 48 Gbps without serious signal integrity issues.

Dog

12:13 AM

Heck 1m is too long for some of my uses

I think the vast majority of bundled cables work for the vast majority of people. I think they're 1m or 1.5m, not too sure

If you need >2m you go out and choose and buy your own cable anyway

Bob

@Dog yea, I'm thinking 2m for monitor to under desk, or very large tv to console. 1m for normal tv to console. 0.5m for pc next to monitor. 3m for tv mounted on wall.

Michael Frank

ha, bundled cables? Nobody just GIVES away an HDMI cable.

bwDraco

@MichaelFrank My Acer H226HQL came with a full complement of cables: VGA, DVI, and HDMI. All cables were 1m long.

Dog

@Bob I used a 5m for my PC under desk to loft bed monitor on a swing arm. Was longer than I needed but my flatmate had it lying around spare

He used the 5m for running HDMI from his desktop in one room to VR headset in a different room

Bob

@Dog I can barely stretch a 1.5m from pc (under desk) to second monitor a bit further than primary

so 2m would've been more comfortable

5m would be... uh, mostly coiled up

Dog

12:15 AM

Before that we used to use the 5m to run from the AV receiver at one end of the room to the projector on the ceiling at the opposite end

@Bob Yeah, mine do have to stretch a bit and are too short to route neatly around the monitor stand arms

Bob

@bwDraco but, really, if you're doing home theatre... you can figure something out.

mount a NUC to the TV/projector, even

there, now a 30cm cable will work fine

Dog

So aside from the single 5m HDMI cable we shared between the two of us over 3 years, every other cable we have/need/use is <2m

I wouldn't mind a 10m active thunderbolt 3 cable tbh

Bob

:34555741 uh, yea, no

Michael Frank

At the end of the day, someone that's buying an 8K TV, is not going to be going out and finding the cheapest "Generic" HDMI 2.1 cable they can find.

Bob

as much as you might love STP, UTP is perfectly fine...

coiled or not

@MichaelFrank at the same time, they shouldn't need to pay $100 for some fancy cable

Dog

12:21 AM

@MichaelFrank They advertise it as Thunderbolt 3 up to 40Gbps but it's actually only capable of Thunderbolt 1/2 speeds.

Michael Frank

@Bob But don't you want to make sure all the 1s and 0s make it?!

@Dog That sucks.

Dog

@Bob Meh. I suspect if I plan on using Thunderbolt 3 as a poor man's substitute for 10GbE, I'm going to have to pay a premium for cables to avoid paying a premium for 10GbE cards

@MichaelFrank Yup

Hennes

uhm, no

Bob

@Dog well... you'd need an active cable apparently o.O

Hennes

I got TB3 for that purpose in my new desktop.

Dog

12:23 AM

Not just a software/firmware bug either - the electrical schematics show it's only wired with half the lanes

Hennes

And the cheap solution turned out to be $37 for TWO 10Gbit cards.

And while we are on the subject of cables..... and Eur 40 for a cable

Dog

@Hennes Try get a modern, well supported 10GbE card with transcievers that supports SR-IOV for less than $100, good luck

Bob

@Dog ow

Dog

@Hennes Or in the case of Thunderbolt, $0 because the "cards" already come with your machine, and maybe $10 for a cable if you don't have one already

Should also point out... try getting a $37 10GbE card for a laptop...

Hennes

Uhm, they came with the machine... but I had to get a motherboard Eur 40 more expensive than the board I wanted but which did not have TB3

Dog

12:26 AM

@Bob Yeah. Until now I was mighty impressed with the thoroughness of Dell's TB3 implementation... :-(

Hennes

The cards I got where a pair of Mellanox ConnectX-2 Single-Port SFP+ 10GBE NICs.

Dog

They had the most robust and complete TB3 implementation of anyone to date.

Bob

@Dog wait, are you talking about the new ones, or all of them?

and how did you find out?

Dog

@Hennes So no transceivers, doesn't support PCIe 3, and impossible to fit in a laptop... Useless

Hennes

Does not do PCIe v3, does not need PCIe v3.
8 lanes at PCI-e v2 speed is (8x 5Gbit/sec) is more than the card needs.

If put in a x4 slot it is still more than needed

Dog

12:31 AM

@Bob Article

@Hennes Expresscard and MiniPCIe only have one lane

Hennes

One? How did you manage that? expresscard slot to full sized PCI-e thing?

Easy solution, replace it with a desktop motherboard

Dog

Yeah, I'm going to glue a desktop motherboard to the back of my laptop. Real practical.

Hennes

Which is easy for me to say, because a desktop is large and connot be moved,
And a laptop is small, tied to a desk with a cable and will not be moved

Dog

@Bob: Still trying to find the article but got 100 pages of CES news in the way -_-

Michael Frank

Hennes

12:33 AM

right middle is for the answer on dog

Bob

@Dog oh, thought you tested for yourself

so old models or the newly announced ones too?

Dog

@Bob That would involve me having one

Though if I had one I probably would mind less cause I'd have the Alienware with its own proprietary graphics port anyway

No sign of a new Surface Pro at CES it seems

Bob

hmmmm

maybe I should wait another year

Burgi

@Hennes i think the joke is that there is no answer

Bob

for a CPU that supports PCIe 4.0

Hennes

12:41 AM

@Burgi Look below search, Below the ea part

then vertical down to the right lower corner

Michael Frank

Yea, the answer is actually there.

allquixotic

@Bob annoyingly, with Intel at least, the first PCIe 4.0 boards/CPUs will be of the -E series, probably, if history is any judge.

maybe Skylake-E or Kaby Lake-E

or even Cannonlake-E

Dog

@Bob: notebookcheck.net/…

> Schematics of the XPS 9350 show that its TB3 controller is hardware-limited to speeds half of those advertised. This may affect all notebooks with a single TB3 port, including the XPS 9360, 9550, 9560, M5510, and M5520.

Bob

@allquixotic dammit. not Coffee Lake then?

Journeyman Geek

>_>

What needs all the bandwidth?

Dog

12:47 AM

@Bob Coffee lake is not going to be on all platforms, probably laptop only

Bob

@JourneymanGeek me?

Journeyman Geek

not who, what? ;p

PCIe x8 v3 is enough for most modern graphics cards... and x4 for NVMe storage ;p

Hennes

Impatient people?

Bob

@Dog ach. and Cannonlake is Y only...

@JourneymanGeek more bandwidth on 1x slots

Journeyman Geek

ah. for? ;p

Bob

12:49 AM

most/all non-graphics (i.e. chipset) slots are 1x

Hennes

@JourneymanGeek That is what I have atm. x8 for graphics, x8 for 10Gbit, and NVME at x4

Neh, then you just have the wrong boards

Bob

@Dog ah. thanks for reminding me H is mobile -_-

dammit. then the next desktop parts would be 2018/19

Hennes

My X58 board was x16/0 (or x8/x8) and x16 and x4 and x1

Bob

in that case I might as well go in with kaby and worry about PCIe 4.0 in 2020

Dog

@Bob Actually there's talk of 6-core Coffee Lake-X

Journeyman Geek

12:51 AM

;p

Hennes

Fileserver has three physical zx16s (at 16/0, 8/8 and 4)

Dog

And 4/6 core DT Coffee-Lake-H

Hennes

Not sure out of the top of my head for my main desktop, but it was imilar-ish

Dog

So either they changed it or this is a different leaked roadmap

Bob

@Dog X costs too much :P

allquixotic

12:51 AM

@Dog BGA desktop? O_O

Bob

and that'd be 2018 anyway, possibly late 2018

Dog

@Bob We don't know what X is anyway

allquixotic

!! s/possibly late 2018/probably mid to late 2019, knowing Intel/

Bob

@Hennes I'd rather any USB or SATA cards I add don't take bandwidth from the GPU

dunno how AMD chipsets handle it

Dog

It's going to be a new platform, new socket, and very different to the existing -E/-EN/-EP series

allquixotic

12:53 AM

and fucking with my server broke cavil ofc

Hennes

I never had a shortage of USB ports. No need for add-in cards to add more.

Journeyman Geek

@allquixotic its probably not your fault ;p

Dog

For one, it'll have integrated graphics. For two, it won't use the same socket as the -E/Xeon E5's

Journeyman Geek

ah

Hennes

As for SATA cards. Yeah (though in my case two HW SAS RAID cards)

Bob

12:53 AM

@Dog Oh, I was thinking along the lines of E :\

as in, i7-6xxxX

Journeyman Geek

@Bob I suppose raid is a reasonably compelling reason

allquixotic

@JourneymanGeek of course it is; I rebooted the server

Dog

Bob

@Hennes eh. USB 3.x

since z270 mobos apparently use custom controllers for USB 3.1

Hennes

On the X58 board: No need. eSATA pendrives are plenty fast.
The other came with it.

Bob

12:54 AM

and custom controllers have traditionally been quite dodgy

allquixotic

Linux thinks my physical NIC iface is already bound to a bridge, but brctl doesn't show it, so I can only conclude that macvlan for lxd somehow claims a device as a "bridge"

Dog

Burgi

@Hennes @MichaelFrank you are going to have to highlight it for me

Dog

Well that's not confusing at all

Journeyman Geek

@Dog wait, so they'll release two families at once, with the newer family being cheaper, and I supposed more nerfed than the older family whaaaaat?

Bob

12:56 AM

@Dog wat

Journeyman Geek

... that makes even more sense... not

Michael Frank

@Burgi 3 down, 8 across. diagonally down to the right.

Bob

uhhh

I assume the newer gens will be clocked higher?

so TDP limits => fewer cores?

only way this'd make sense...

Burgi

@MichaelFrank huh...

Dog

1 min ago, by Dog

Well that's not confusing at all

Journeyman Geek

12:57 AM

that vaguely makes sense

but you could just call them the same name and differenciate by name

Bob

dunno why they'd even bother with Skylake-X at this point though

Dog

@Bob There is no sense. Intel lost it when they renamed Core M's to Core i7s

Bob

considering Kaby's supposed to be nearly identical and have a more mature process? :\

@Dog well, we'd already long past the point where any real pattern for their CPU naming existed

Dog

Ah. that's the one I was thinking of

Coffee Lake will only be Iris Pro U and DT-H

U/Y will supposedly skip straight to Cannonlake

Bob

Q: Write speed requirement : 1.1GB/s possibilities?

We will have a machine at work, that on peak performance, should be able to push 50 ("write heads") x 75GB of data per hour. That's peak performance of ~1100MB/s write speed. To get that from the machine, it requires two 10GBi lines. My question is what kind of server+technology can handle/store ...

Dog

1:00 AM

Which contradicts the other site's "leak" but this one says Intel on it so...

Oh wait that's the mobile-only roadmap

@Bob I'll take the 28w quad-core with Iris Pro tyvm

There's only one laptop I know of with a 28w Skylake-U and Iris Pro, and it's performance is awesome

Bob

@Dog yea but you're buying portable machines

I'm buying a giant box

Dog

I might buy that Eurocom laptop with a i7-7700K in it

Bob

ok, not-so-portable machines :P

Dog

I've figured I can kill three birds with one stone. Solve my gaming laptop problem, solve my desktop problem, and solve my too-many-machines problem.

Buy a laptop, that's faster than my desktop and use it as a DTR

And with a socketed i7 7700k it'll be able to upgrade to an 8800k or whatever the 6-core Coffee Lake processors will be called

I only wish the 45w HQ processors weren't soldered BGA's.... would be perfect to get a regular 45w gaming laptop and upgrade it to CFL in a year's time

Bob

@Dog solve your too-many-machines problem by buying a new machine :P

(yea, replacing the old ones, but it still sounds funny)

Burgi

1:07 AM

the recruiters have forwarded me that linux sysadmin job again if anyone is interested

Dog

@Bob lol yeah

Well the main issue was one tablet, one gaming laptop, one desktop = three machines

Whereas gaming laptop as DTR + tablet = two machines.

Also no issue with having to copy stuff back and forth off my desktop to laptop when I go on a trip because it'll be the same machine

So it looks like anyone wanting to watch Netflix 4K on an Iris-equipped quad-core will have to wait till the middle of 2018

Bob

I understand that modern computers use UEFI not BIOS. And i've heard of EFI partition as something that computers with UEFI have. Do all computers nowadays then have and require an EFI partition?

and it not then what's the advantage?

Bob

hm

I'll probably have to pick out a cooler for Kaby, sooo...

I suppose default is the ol' EVO 212

Journeyman Geek

@barlop EFI partitions let you run software preboot.

so stuff like your bootloader can sit there, and its generally just a little faster

barlop

is it necessary though?

Bob

@barlop UEFI is a standard. "BIOS" is a generic term, but usually means a clone of the legacy IBM PC BIOS in this context. Motherboard firmware these days do implement the UEFI standard, yes, but they also usually implement the legacy BIOS in a compatibility mode.

UEFI exists because BIOS never was a proper standard.

@allquixotic ^ and two lines below that ;p

@barlop UEFI is a firmware standard

Bios is vaguely a firmware standard

barlop

i'm not disputing that.

anyhow, what I was asking, is can you have a UEFI with no EFI partition and still boot windows..?

Journeyman Geek

3:24 AM

er

I think so

you might need to throw it in compatibility mode though

barlop

Is it always 100MB?

Bob

@barlop The UEFI standard itself requires support for booting from an EFI System Partition. So every motherboard that implements the UEFI standard must support it.

Journeyman Geek

I think that's what MS does

Bob

It also allows an alternative Compatibility Support Module that pretends to be a legacy BIOS.

Most (desktop) motherboard firmware implements that too.

Some don't. Especially laptops.

Journeyman Geek

Don't forget though, with gpt, there's no "3+1(x)" partitions

Bob

3:27 AM

Tablets usually don't have CSM.

Journeyman Geek

and 100mb is... meh on modern systems

Bob

Basically: whether you can boot from a non-EFI config will depend on the specific firmware, not the UEFI standard overall.

Journeyman Geek

and yeah, everyone seems to say 100mb is the minimum

3:29 AM

There's technically no reason you can't boot GPT from legacy BIOS (or via CSM). GRUB will happily do that.

Buuuuuuuut Windows specifically requires GPT-formatted disks to boot via UEFI, and MBR-formatted disks to boot via BIOS(/CSM).

@barlop read this, it's a good primer: happyassassin.net/2014/01/25/…

But, basically, there's a difference between what the UEFI standard requires, what the UEFI standard allows, and what a specific firmware implementation does.

@JourneymanGeek Is that the famous Sandra?

Journeyman Geek

@Bob no

That one is actually halfway competent

Bob

@Conor Connect to? Connect through? What exactly are you trying to do?

@bwDraco which cooler did you go with?

bwDraco

@Bob For the current proposed Alastor build, it's a Corsair H80i v2.

(Closed-loop liquid cooler, 120mm radiator with push-pull fans)

@bwDraco Ah, liquid. I looked at em, but I want something quiet.

Liquid's always got that pump noise going on.

bwDraco

My main requirement isn't bringing noise to a bare minimum as it's not in a home theather or other extremely noise-sensitive environment. I just want robust cooling with reasonable noise levels under load.

I'm kinda used to 50+ dBA noise from my laptop under maximum load...

Dog

@Bob liquid is quiet.

A properly configured pump is inaudible. Quieter than the quietest CPU cooler fan at minimum speed.

Bob

@Dog :\

I've never used liquid... was just going by a couple reviews

@JourneymanGeek Kaby Lake is a bit of an aberration. It was never meant to exist, and quite literally as Ars says, just a filler so OEMs can stick a new label on products shipping this cycle while Intel remain too incompetent to have learnt from their mistakes and had to shove something in at the last minute after the "real" product remains miles away

@Bob well if you use a stock AIO system, maybe. But even a cheap crappy noisy pump can be made inaudible with some basic modding.

By basic I mean as simple as dangling it by the tubing instead of screwing it to the case (or use silicone isolation studs) and connecting to a 7v molex

Journeyman Geek

dangling it by the tubing is a terrible idea

Dog

It works

Journeyman Geek

lol

Dog

Tubing works 80% as well as dedicated decoupling foam or rubber pads

I mean it is basically rubber hose anyway.

Bob

...I'll stick with air, probably :P

could always switch to liquid later anyway

Dog

If you don't want to dangle it with tubing but are too cheap for special screws you could just ad well dangle it with rubber bands or string

Water is overrated.

Bob

not like I'm gonna be doing any real OCing

Dog

I get just as good an overclock with a low-noise low-profile mini-ITX air cooler as I did with my £350 dual-double radiator custom loop

Mind you the main reason I got the water cooling was to cool the ridiculous furnace that was the Radeon 290X but ended up returning that and getting a GTX 970 instead which used half the power
