7900X reviewed!

Up until now, Intel has typically given desktop users a choice; do you want massive single-thread performance (Core i7-7700K); or would you prefer genuine multi-core goodness (Core i7-6950X)? AMD Ryzen made multi-core potential available for less, but the Core i9-7900X is the first chip to legitimately excel in both scenarios.

It is practically as fast as the Core i7-7700K in terms of straight-line speed, and with 10 cores able to maintain 4GHz under load, the Core i9 raises the bar in Handbrake and Cinebench. Impressive IPC and massive mega-tasking capabilities in one $999 chip. Is that your wallet opening I hear?

Overclocking:

They were able to achieve 4.7GHz at 1.25V, that's EXTREMELY impressive! (Without a delid)

Overclocked benchmarks:

If the CPU was delidded, higher clocks would have been possible

Power consumption:

Price/performance is not great, but, honestly, that's not unexpected

Very very promising CPU with hot price. Looking foward enthusiast war. Intel you impressed me this time. Gj, you've didnt impress me since Skylake reveal.

impressive chip!

[LegendKillerRG]

Meh.. ThreadRipper.

[NumLock21]

Way out of reach for many...

The 7900X is, but the 7820X and the 7800X aren't

[Sauron]

1000$? Threadripper will offer 16 cores for less than that. Sure, in single threaded workloads it won't be nearly as good but... who cares? You aren't going to buy this for games anyway. I guess it will be good for the extremely niche audience that are professional streamers.

[Mister Snow]

I love how "mega-tasking" is a thing now.

Even more impressive if you compare it to the 6950X, it significantly outperforms it in pretty much every single test!

And in AVX workloads, when using AVX the 7900X will destroy the 16 core threadripper

Any thermal results lol?

Don't rush too much. We haven't seen Threadripper in action

 

[HKZeroFive]

Not surprising to be honest. Intel makes some excellent but absurdly priced processors... on even more absurd platforms altogether.

[VagabondWraith]

Oh boy oh boy oh boy. Can't wait to get my hands on that 7820X! VERY impressing showing. Now you can have BOTH single thread AND multi thread on one CPU. No more one or the other!  

 

Cant wait for Monday for the rest! ???

IPC of Kaby Lake

OC headroom of Kaby Lake

More cores

TR is Ryzen x 2.  It's performance isn't going to be surprising.

We don't have to, since we already know that Ryzen's AVX performance is very bad:

[Carclis]

Performs better than expected, but I gotta say it really looks like Intel's pushing that silicon/design to it's limits. In the video encoding scenario perf/watt starts to get thrown out.

Better than Kabylake  Thanks to the larger L2 cache

Agreed, you'll get more multi-threaded performance with Threadripper and more value.  That's what AMD is for.

 

If you want the best of both worlds, you'll have to pay more.  That's what Intel is for. 

 

This applies to almost everything in life.  

 

Guys who use their rigs for work and play will love having high single-threaded and multi-threaded performance.

[21rkosta]

id say the usefullness to price of this cpu definitly depends on the price of AMD's Threadripper

Probably because of H.265 which uses AVX

ok but still maybe they made little tweaks to architecture without annoucing it.

Nope, they didn't Threadripper is just 2x Ryzen

If they had a new stepping their marketing team would be all over it calling it Zen+ v2.0 Extreme X Edition

Instructions sets are "tweaks" you're not likely to see happen within an architecture without a complete refresh or something equivalent.  Even then, I highly doubt it.
