@Burgi Why not ask your minion? ;p

Dog

Leaked Zen benchmarks show it "soundly beats" a 3.0 Ghz 10-core Broadwell but fails to beat a 2.2 Ghz 10-core Broadwell in the same benchmark -_-

I think someone has reading the chart the wrong way round.

Aibobot

arn't xeons often but not always more powerful than core i7s?

Bob

@Aibobot ...that's exactly that I was thinking!

djsmiley2k

'We are very busy at the moment'

Dog

@Aibobot Xeons tend to have more cores, but usually lower clockspeeds than HEDT i7s

In this case, it "beats" a 3.0 Ghz i7 but not a 2.2 Ghz Xeon. Wat

Aibobot

@Dog was about to say, core i7s tend to have better single core performance...

Bob

9:39 AM

@Dog For 3D rendering? Isn't that pretty much the optimal use-case for more cores?

Dog

@Bob Same core count on both. Same cache. Same socket. Same generation.

Aibobot

*single thread

Dog

Same physical chip with a few bits in the CPUID string flipped.

Bob

@Dog Yea, I'm talking about the whole "among Xeon, beats i7" quote :P

Aibobot

unless they mean something like a xeon D

;p

Bob

9:40 AM

eww

@Dog Wait. Doesn't Xeon usually have more cache?

Dog

@Bob They're quoting a 10-core Broadwell Xeon vs. a 10-core Broadwell i7

@Bob No, it's the exact same chip

Exact same cache.

Heck if you're lucky they forget to lock the multiplier on the Xeon as well and it's literally an i7 Extreme with ECC.

Aibobot

for some reason I'm thinking Xeon v5s are essentially mainstream core equivilents...

soooo

if this is the 32-core part

Dog

@Aibobot E3's are literally the same chip as their same-socket i5/i7 brethren (LGA 115x)

E5's are literally the same chip as their same-socket i7 brethren (LGA 2011x)

Bob

:\

Aibobot

yup

Bob

Could be anything, but if it is the 32-core part... congrats, your 32 cores are on par with 10 Skylake cores?

Aibobot

lol

Dog

9:43 AM

@Bob Previous behnchmarks published by AMD have been using an 8-core part though

Aibobot

which might make sense for some workloads

the 32 core part might be handy for virtualisation

Dog

I somehow doubt they'd be publishing 8-core benchmarks if they had a 32-core available on release day

Bob

@Dog Published... how did those benchmarks measure up anyway? I haven't been keeping up.

Dog

@Bob Very biased, but competitive with Broadwell on IPC in the one very specific scenario they detailed

Aibobot

@Dog essentially they want the same core design to scale from laptops to servers

Bob

9:44 AM

I'm curious how much they can actually accomplish with 32 cores. TDP limits and all.

Aibobot

so 32 core would be the opteron equivilent

Dog

@Aibobot Sorta, but so did Intel, yet Intel still delays release of >10-core parts by a year, and >20 core parts by 2 years

Aibobot

Does AMD even have a server part at the moment?

Dog

@Aibobot They still sell Opterons

Bob

@Dog Which Microsoft uses

Aibobot

9:45 AM

@Dog practically tho, intel have what 2-3 different core families?

atom's not dead...

Bob

protip: never ever get an A1 to A4 VM from Azure

Dog

@Aibobot Well if you count Atom, yeah, but I've never had one and never will

Bob

because single-thread performance is atrocious

Aibobot

@Dog I do

Dog

Aside from Atom, the Core core goes from <5w tablet to >150w server

Aibobot

9:45 AM

there's some roles where its really nice

Dog

Atom on the other hand goes nowhere... mwahahaha :-P

Aibobot

yeah

Bob

@Aibobot The Atom brand is effectively dead now, but the arch lives on in Celeron/Pentium

Dog

But if you want to specifically include low-end parts, AMD has an ARM core too

Aibobot

I thought they were doing the x3/x5/x7 thing

Dog

9:46 AM

Opteron A

Bob

@Aibobot Nah, they ditched that earlier this year

Aibobot

ah

Dog

Derp

Aibobot

they're a bit confused on the low end

Dog

They also renamed some Core M's i5's and i7's

Bob

9:47 AM

They're still making/selling them, but no plans for a new gen last I checked

They're going with Celeron branding on laptops, and otherwise Core-M I think

Aibobot

heh

Dog

So Atoms have become Core M's and Core M's have become i7's?

wtf

Aibobot

I do actually have a use for atom-lerons

Bob

@Dog Core-M is still Skylake, not Airmont

Airmont is only Celeron/Pentium N**** now, IIRC

Or maybe J****too

Dog

What can you do with a 3w Atomeron you can't do with a 3w i5?

Bob

9:48 AM

@Dog Save $$?

Aibobot

@Dog that's a good question

yup

Dog

@Bob Sorry, save $$ isn't in my vocabulary

Aibobot

I run an atom-celery box for my home server/dl box

Bob

@Dog Hm. Then these leaks might be a 16-core part?

Since they're apparently beating 10-core Skylake

Or possibly higher clocked

Dog

@Bob Broadwell. There is no 10-core Skylake

Bob

9:50 AM

Or maybe they took a fairly big jump in the last few months

@Dog Argh. Damn model numbers messing with my head :(

Dog

Remember AMD's part is already hitting 4Ghz+ though, and the 10-core Broadwell it beat is a 2.2Ghz

Or 3.0

Aibobot

wait. 4ghz+

Dog

I'm sure the chart is upside down

Because beating a chip at 3.0Ghz and not the same chip at 2.2Ghz just makes zero sense

Aibobot

granted clockspeeds mean little but...

Bob

@Dog The chart is a bit funny

How is the E5-2690 v2 even faster?

It's Ivy Bridge(-EP?), FFS.

Dog

9:55 AM

Oh shit I think I've caught infectious mononucleosis

Bob

Even better is the X5680 up there.

Dog

No, wait, that's a sugar stain from last night

How did that get there... I wasn't even using that part of my body to consume sugar last night

Bob

6-core Westmere-EP at 3.33 GHz base/3.60 GHz boost.

Beating a 10-core Broadwell part at 3.00 GHz base...

Maybe it was dual-X5680?

Dog

I wonder of dual-socket configurations are listed there without a "2x" prefix

Then again, the X5680 was a Westmere part

Maybe 3.3Ghz base but easily overclockable to 5Ghz base.

Well OK not easily - easily overclockable to 4.6Ghz base, 5.0 required a bit of work. But still it was a hugely overclockable part

Bob

@Dog That would explain all the older Xeons above the more modern i7s.

Dog

10:00 AM

5Ghz x 6 = 30Ghz
2.2Ghz x 10 = 22Ghz

So four generations of IPC improvements aside, it's almost feasible

Bob

Guess we'll see next year.

Dog

@Bob No! We must speculate this to oblivion NEW ZEALAND

OOer "The Government suffered a major defeat over Brexit today as High Court judges ruled that MPs must be given a vote before Theresa May (right) starts the EU exit process. The Lord Chief Justice handed down a damning verdict for the Government on a case brought by Remain campaigners"

djsmiley2k

I've always had huge ones, bu because I've never had any issues all the doctors just kind of shruged and went we won't remove them unless somethings wrong

few years later I finally get diagnosed with sleep apnea, and my consultant takes notice when I say about my huge tonsils, he refers me, and I get to 'choose' which hospital to go to

so I chose the private one, the doc took about a 5 second look at my tonsils, goes 'yup there huge and need to come out' and sent me away :D

Route flapping

In computer networking and telecommunications, route flapping occurs when a router alternately advertises a destination network via one route then another (or as unavailable, and then available again) in quick sequence. A closely related term is interface flapping where an interface on a router has a hardware failure that will cause the router to announce it alternately as "up" and "down". Route flapping is caused by pathological conditions (hardware errors, software errors, configuration errors, intermittent errors in communications links, unreliable connections, etc.) within the network which...

Or maybe

Routing loop problem

A routing loop is a common problem with various types of networks, particularly computer networks. They are formed when an error occurs in the operation of the routing algorithm, and as a result, in a group of nodes, the path to a particular destination forms a loop. In the simplest version, a routing loop of size two, node A thinks that the path to some destination (call it C) is through its neighbouring node, node B. At the same time, node B thinks that the path to C starts at node A. Thus, whenever traffic for C arrives at either A or B, it will loop endlessly between A and B, unless som...

djsmiley2k

yeah ty

couldn't think of the term

Ah well, I've emailed them about it and now we fall asleep

rather large important customer, with a VIP visiting, requested it be fixed this morning after ignoring it for like a week :/

I'm not sure exactly what's happening, as I left a ping running and occasionally it arrives successfully.

it's like route flapping but one route is just blackholing it

22 hours ago, by allquicatic

is engine.execute doing connection pooling?

Thanks for the pointer :D

djsmiley2k

surely with connection pooling, it shouldn't have used them all up tho?

instead, it'll reuse them?

bwDraco

Most home networking equipment is not designed to cope with loops.

allquicatic

1:00 PM

@djsmiley2k a connection pool with a max pool size of a sufficiently large size is indistinguishable from an unbounded connection leak

djsmiley2k

@bwDraco I hope to god this isn't some home equipment...

@bwDraco don't forget I'm at work.

@allquicatic true, how large was the pool set to o_O? :D

bwDraco

Managed switches should have ways of dealing with this like STP.

However, I've seen consumer-grade networking hardware in a few small-business environments. While most simpler networks should never experience a loop, low-cost networking gear typically assumes a star topology, possibly with extra branches like Ethernet switches for expansion, and assume that there is only one path to each host.

Dog

@djsmiley2k That's called a routing loop

bwDraco

Hmm. I though Layer 3 networks had ways to deal with loops built in since each router should have enough intelligence to choose a (close to) optimal path...

There's an echo in here ;p

Bagpuss

Bagpuss is a British children's television series, made by Peter Firmin and Oliver Postgate. The series of 13 episodes was first broadcast from 12 February 1974 to 7 May 1974 through their company Smallfilms. The title character was "a saggy, old cloth cat, baggy, and a bit loose at the seams". Although only 13 episodes were made, it remains fondly remembered, and was frequently repeated in the UK for 13 years. In 1999 Bagpuss topped a BBC poll for the UK's favourite children's TV programme. == Format == Each programme began in the same way: through a series of sepia photographs, the viewer is...
