Intel Core i9-7900X reviews are going live!

Just watched the early part of the hexus review and (probably from a previous video) it shows that skylake x has 2 substrates. Any idea as to how/why they would do this?

Sticking my nose in, without reading all 12 pages, is any-one swapping out their 5930k@ 4.5 for any of these chips? Worth the swap?

I'd say not really.

If you want lots of multi-thread performance you should get AMD Threadripper in July/August.

If you want lots of single-thread performance you should wait for 6-core Coffeelake on the mainstream platform.

Skylake-X would only be attractive to someone with a 5930k if you have very deep pockets and want a balance of single/multi-thread by getting the 10-core $1000 chip. And a very beefy cooler to cope with its heat.

By beefy he means custom loop. AIO coolers are barely keeping it under 100c and thats in an air controlled office :o
Warm little buggers.

you're on a 5820k I guess? to be honest there's little point in upgrading as long as yours can OC well.

you've always got the option of a 5960x upgrade in the future, the J code ones seem to overclock better (last batch) and ive seem them go as low as £500 new on ebay.

but to be honest even swapping to a 5960x at 4.6ghz wouldn't change your minimums much, 6 cores is more than enough for gaming.

faster ram might help? some games in particular seem to love ram speed increases.

5820k yes, it's a J batch but i wouldn't put much faith in that, mine is probably an average clocker. Not bad though by any means and still decent.

At the time i first upgraded, i had a 2400mhz 16gb kit of ram, but later got a refund and ended up with 32gb of 2800mhz.. which i guess is almost within the sweet spot today for cost/performance. The kit is over 200 quid now and i only ended up paying around 150 or so for it. If i change out my ram kit i think it would just be added cost for little/no noticeable benefit.

Maybe I'll just wait it out until a worthy improvement comes along, what that is though I'm not sure of yet.

I only game tbh, so that's the only performance in mind, if OC'd for OC'd if I got 20% increase I'd probably make the move, it feels like I've been on X99 forever. so 20% faster or not?

That's probably me out then, I use a H110i and would be overclocking to the max, I don't want a proper liquid cooled system as I like to swap component's out often and it'd make it into a big task.

Anything else out this year?

I remember a certain poster claiming Ryzen TDPs were innacurate.

http://www.anandtech.com/show/11550...-core-i9-7900x-i7-7820x-and-i7-7800x-tested/8

Interesting power consumption for 140W TDP chips.
Click to expand...
That's not full consumption but throttled one.
Without motherboard/BIOS constantly standing on "TDP brakes" it sucks over 200W under full load at stock.
For any overclocking it requires nuclear reactor's cooling system to handle actual load.

As mentioned, we had to use Alphacool's Eiszeit Chiller 2000 to achieve usable overclocking results. More conventional thermal solutions just wouldn't cut it. All-in-ones like Corsair's H100i and Enermax's LiqTech 240 hit their limits at stock frequencies under Prime95. The custom loop threw in the towel at 4.6 GHz.

And even if cooling can keep temperatures under control there's question how long motherboard's VRM (+socket) can handle that kind power draws without something burning up.

The majority of people using this forum plus people who game and don't care much for more than 8 cores. It's an overclocking forum after all.
Click to expand...
With Coffee Lake being basically just rehashed Kaby Lake it's good bet that six core Coffee Lakes draw more power under full load at stock than 8 core Ryzen.
So wouldn't expect much of sensible overclocking from them.
And I mean overclocking CPU, not overvolting/overheating it...
(as in 1,25VID Q9550 at 1,2V and 3,7GHz)

If manufacturing process didn't cap max boost clocks in Ryzen under lower load Intel would be hard pressed to maintain performance lead in most test.

The last 3 years when I priced up an upgrade, that's how long I've been waiting to upgrade, it would be around £650. The big difference from then to now are the motherboard prices.
Click to expand...
Yeah I think Linus' Skylake-X video mentioned that motherboards would be in the $300-500 range. I remember being horrified at forking out nearly £250 for mine 8 years ago. :/

I guess inflation and all that...
 
Having gone through the screaming deltas at 5000rpm 10 or 15 years back and latterly an FX9590 creating a sauna in the back bedroom, I have outgrown maxpowa for maximum cool or at least quiet.

Ah yes I remember those times when I thought it was OK to cool with delta fans. Those things could be heard throughout the entire house, I don't think I'll be doing that again lol.
