7980XE vs 9980XE?

[sproggit]

So having spent a silly amount of time saving for a completely over-the-top new system, I get right to the edge of pushing the button on an order, only to see Intel announce effectively a replacement for my CPU of choice.

 

From what I can make out, the 9980XE runs faster, can be over-clocked, but has a soldered IHS (so no de-lidding and liquid metal upgrades).

 

I appreciate that the right thing to do will be to wait for someone to run a side-by-side comparison between these two processors, but I am interested in asking around to see what the prevailing view is. I think my choices might boil down to paying a silly premium for the 9980XE, or maybe hoping for a slight dent in the price of the 7980's once the newer model ships.

 

But I'm a long way from being a CPU expert. Is there anything else I should think about in terms of the CPU selection? (Constructive...) feedback gratefully received...

 

TIA

 

Rest of build:-

Asus RoG VI EE X299 with EKWB water block

G.Skill Trident 4266MHz RAM (4 x 16Gb kits) [Yes, I know that RAM speed is way more than the Mobo will support, but hoping it will be stable if I OC the rest of the build...

2 x (Gigabyte) 2080Ti's, both wate rcooled with EKWB full coverage blocks, in SLI

3 x Samsung NVMe SSDs ( 1 x 1Tb [Office], 1 x 2Tb [Gaming], 1 x 512Gb [Linux] ). Note that this will require the "riser card" supplied with the RoG mobo to get 3 x M2s connected...

9980XE is just a soldered 7980XE, with no IPC gains or anything like that. Tbh you're better off delidding and applying liquid metal to the 7980XE if you just want performance.

The difference is 0.4Ghz Base speed and 0.2Ghz Turbo Boost Speed. Everything else appears to be the same. Now mind you I have not taken into account any sort of new features that his CPU exhibits over the previous generation such as for ex: 7th gen CPUs having dedicated hardware encoders for 4K.

 

However, considering price for price they are similar enough at current *NEW* pricing the 9980XE is the a better choice IMO (7980XE 1903$ on Amazon, 9980XE MSRP of 1979$). If we are talking about a 76$ difference in a 300$ CPU then this is a much different story. Of course you may be able to find offloaded or even used 7980XE's for cheaper since it is not new. Then again, the solder will already make it so you don't need to de-lid so that is 1 thing you don't have to worry about unless you already had an LGA2066 de-lidding tool.

 

Final note is that, the base speed of +0.4Ghz for 3.0Ghz is pretty important if you don't plan on overclocking and will make use of all 18 cores simultaneously. This is dependent on temperature as well.

both are really slow and only designed for poor people, you want to wait for the W3175X to truly be in the pc master race.

It's hard to tell whether or not the solder will be a good thing here. As der8auer pointed out, in the consumer series they made the die a bit too thick and so even despite the solder the thermals aren't really the best. Well, liquid metal improved thermals even in Broadwell-E chips but not so much as here.

 

I'd wait to see how they did it in HEDT because you might be looking at potentially terrible thermals without die lapping. 

 

Also, it's just me but I'm not alone in this - the Asus Apex x299 looks better than Extreme. And has cooler name if you're into that sort of thing

Would be an interesting video: 7980XE with liquid metal vs 9980XE stock. xD

In a round-about way that's been done already.  Just look at the current 7980XE benchmark videos from GamersNexus and Jayz2Cents and compare them to their 9980XE videos.
