Skylake-X (Core i9) - Lineup, Specifications and Reviews!

Nightfire said:
So niether the review you linked and the review I linked offer a good picture of gaming performance?

I am sure we can find a review where the 1950x gets more than a 15% gain in mt.

Talk about cherry picking. Find the one game that shows a 31% difference and ignore everything else including the review you actually linked.

Are you trolling us?

I only mentioned the game where the i9-7900X is 31--38% faster because I wanted to demonstrate you that the SA review of games was incomplete. SA only tested four games where both chips are close (the higher gap measured was only 9%). I am not taking that game and ignoring the rest. I have said to you that the average gap between both chips is 10--20% for gaming as other reviews have found. The average is 10--20% because the i9 is 31% faster in some games, and only 5% faster in other games.

The 15% gain in MT applications is an average of 13 applications. You can find specific workloads where TR is 30--40% faster, but the average is only 10--15%.

Why is so difficult to understand than the i9 is better from a global point of view? From the review:

In the end Intel’s i9-7900X appears to offer the best combination of singlethreaded performance, multithreaded performance, and efficiency at the $1000 price point. It’s not as fast as AMD’s Ryzen Threadripper in well threaded tasks, but it offers significantly stronger performance in single and lightly threaded workloads while remaining more efficient than the competition. More to the point its performance in multithreaded workloads is really quite good. Given the massive disadvantage it has in core count, the gap in performance is smaller than one would expect.

:cool:
 
Anyone seen any reviews of the larger i9's? I'm curious if they're made with another process than the smaller (10 and below). They seem to have a bigger die, so maybe they overclock better?

Reviews are hard to come by for x299. But I want to see if larger L3 can improve the performance even more. In some apps and games that don't push past 4 cores, the 7900x is a bit faster than the 7820x even at the same clocks. The 7800x does even worse with its smaller L3.

Since the lower clocked 7980x always does better than the 7700k, and the 7700k always does better than the 1800x, the only way this would make sense is if the game scales to 6 cores max. I would expect the 8700k to get equal or better scores than the 7980xe.

Or the single thread performance of the 1800X is simply too weak to handle the main worker thread. Zen IPC is more on SB level than not these days.

7980XE can turbo cores up to 4.4Ghz.

I know you love baiting with that Ryzen=sb ipc crap and I am sure you can dig up a 5 month old obscure review, but my point is that it is evident that a 8700k would match or beat the 7980xe weather it is game, gpu, or cpu limited.

Did I hear Sandy Bridge? ;)

R3 1200 ~ i5 2500k ~ R3 1300X.

I know some AMD fanboys like to pretend that RyZen IPC has increased since launch thanks to magic BIOS/AGESA updates, but it is not true. The above review is less than two months old.

This is SOP for the IDF crew. Exactly as I called it. Obscure link, unknown ACTUAL bios date, test perameters, etc.

It is a well-known and respected review from HFR. I provided the link dozen of times. Parameters are stock for chips, latest AGESA/BIOS, 1080p,...

And yet you keep getting called out on it...

http://www.guru3d.com/articles_pages/amd_ryzen_threadripper_1950x_review,10.html

Here we see Ryzen between Broadwell and SKL.

TR reviews are always 1.0.0.6 afaik. That is why I like to use them. Ryzen is there as well, but of course, it is the same.

Tell ya what: show me ANY IPC comparison on ANY review site where SB matches TR, and I will go away. Promise!

(i)
I already gave you an average gaming bench where Zen IPC is at the Sandy-Bridge level,

4C/4T Zen @ 3.1GHz (stock) ~ 4C/4T SB @ 3.3GHz (stock) ~ 4C/4T Zen @3.5GHz (stock)

but they aren't CineBench. Remember Cinebench is a favorable case for Zen.

(ii)
Guru3d get higher CB15 scores for AMD chips than other reviews.

(iii)
The only AGESA that did bring performance optimizations was 1.0.0.4, which reduced latency about 6ns. Next graphs is from HFR review older than the one that I gave you before

The 1.0.0.6 version has not improved performance at same clocks, simply provided more stability and levels for overclock.

It's so fast it should be illegal. 7980XE is the only one with all the L3 Cache intact in respect to their Xeon brothers.

As someone buying a pair of said Xeon brothers, this makes me happy ! That processor is about the same cost as the Xeon 6144.

:D
 
How much faster is the 7820x than my 5960x clock for clock?
I game at 4k, Rift, and browse.
