Discussion Intel current and future Lakes & Rapids thread

[dangerman1337]

I really cannot see Intel having RPL-R take on Zen 5 & Zen 5 V-Cache if that's true (though DigiTimes AFAIK have been inaccurate at times with MTL partially having TSMC N3), because if they can't get MTL-S out then they have to get ARL-S out ASAP even if it's just a less ambitious core count. They can't afford to mess that up.

Alder Lake is 10+++.

Yes, I totally forgot about

Cannon Lake 10nm 3.2GHz
Ice Lake 10+ 4.1GHz
Tiger Lake 10++ 5GHz
Alder Lake 10+++ 5.5GHz
Raptor Lake 10++++ 6GHz
Raptor Lake Refresh 10+++++

Now we're back in the "+" business again!

What frequency improvements could RLR bring?

It being mobile focused is nothing to do with it being their first attempt at chiplets.

MTL/RWC just isn't good enough to be worth bringing to desktop. ST perf gains just ain't there against desktop RPL.

EDIT: Also I have no clue what the whole CPU+SoC+IO die thing is all about. That's just nonsense.

I have heard this too. Lion cove in arrow lake is the next desktop platform.

 

[poke01]

if arrow lake desktop is on tsmc 3nm then Apple and AMD better watch out.

no more with Arrow Lake desktop, Intel will go to TSMC 3nm according to rumours.

Intel Xeon W9-3495X Reviews are going to be released today at 9 a.m PT make sure to tune to STH, PugetSystem, Phoronix and a few others, there arent going to be many

Why the heck would I do that?! I'll just check this thread for your posts. Jeez...

Uh isn't it officially stated to be 18A? Unless I'm confusing it with something else...

You are. Intel's communications have been confusing, but ARL is using some combination of N3 and 20A, with the latest rumor being N3 for desktop, and 20A for mobile.

It's not a good showing I'm afraid

Sapphire rapids seems like an utter failure, cant even beat Zen3 in nether ST or MT performance, while sucking down much more power ?

Intel Xeon W-3400 Content Creation Preview

Intel has announced their latest Xeon processor families, including the W-2400 and W-3400 lines. While there is still several months to go before the sales embargo, we are able to give a preview of how these processors perform in various content creation applications.

Sapphire rapids OC = 1100w in Geekbench5 @ 4200mhz and only 1000mv (limited to above 1k amps!)

Anyone wanna guess overclocked powerfigures for AVX512 ?

Might make sense for other reasons to stick with Raptor Refresh... DDR5 prices, N3 wafer prices...

 

[nicalandia]

Holy Cow.

I am

Me too, I was expecting to at least be 5% Higher than Zen3 based TR PRO

 

[Hitman928]

At first glance, it seems like Intel's attempt at doing "chiplets" is even less efficient than AMD's method from a perf/w perspective and maybe even just performance. Losing to Zen3 on single/lightly threaded work is very surprising to me. I expected that to be a clear win for SPR with a minor win overall in MT. Losing outright is a shock. No wonder Intel is pushing their accelerators so hard in their PR presentations.

 

[Saylick]

142W idle power for the high performance setting... Wtf is going on there?

It's getting warmed up for all the hard work it has to do!

I agree.

Okay I feel stupid, because I thought 18A to start, realised that Lunar Lake is the one that's 18A and that ARL is 20A instead and then wrote 18A anyway

Though that being said I didn't know about the desktop one utilising N3.

Der8auer has a stock 3495X on a better MB, This times it's basically tied with The Zen3 Based Threadripper PRO 5995WX, but it consumes Over 500 Watts of Power.

That's wall power but even still, that means the CPU has to be spiking well over 500W to get that much power draw from the wall. Like closer to 800W.

Considering the boards were designed and ready for release many months ago it's genuinely very surprising to see what I can only assume is half baked firmware causing that excessive idle power.

I mean it can't be EMIB causing it, one of the biggest reasons it's even there is because it saves a tonne of power (at a given bandwidth) compared to normal packaging techniques.

So basically with the power limits removed, i.e. not really "stock". I would say it's out of the box performance rather than stock.
