Intel's Future Chips: News, Rumours & Reviews

https://videocardz.com/69457/specifications-of-intels-core-x-i9-and-i7-series-supposedly-leaked

Not shocked; called it last week.

Prediction: The same people who boast about how Ryzen wins in synthetics will complain that these CPUs won't offer any advantage in gaming performance.

The full lineage and specs

With IPC above Kabylake and turbo up to 4.5GHz, the new i9 series will be excellent choices for gamers

Prediction: Price >$2K

Is it seriously i9 or is it actually i7 Extreme Edition?

To be fair, more cores using the same architecture would beat Ryzen is pretty much every benchmark under the sun, by virtue of the existing IPC advantage Intel has.

Skylake-X > Skylake's IPC. Skylake-X bumps the L2 cache from 256KB per core to a whooping 1MB per core. Also, it supports AVX512. Add to that the architectural improvements of Skylake, and it becomes a different beast. lol

Oh, and one question. Does Haswell-E have more IPC than Haswell at the same clock and core count due to the increased L3 cache? Or is the increase nonexistent?

Depends if you factor L3 performance into the IPC equation.

I typically lump all processing impacts aside from Clock Speed under "IPC" when I do my comparisons [Performance = Clock * IPC * Num_Cores; its simplest form], because there's no real way to figure out processing impacts at that low a level. So by my metrics, yes, "IPC" goes up by virtue of the chip being every so slightly faster at the same clock (assuming the extra cores aren't doing anything).

Others here would argue otherwise, using a more narrow definition for IPC.

If the data is not in the L3 cache the CPU has to access the main memory which is very slow and implies the CPU will lost cycles waiting for the needed data to continue with its work. Those extra cycles increase the CPI, (cycles per instruction), and thus reduces the IPC (instructions per cycle)

CPI = (1 / IPC)

Similar thoughts about L2 and L3 caches. If data is in the L2 cache then CPU doesn't waste cycles accessing the slower L3 cache. The L2 increase on SKL increases the IPC on workloads are sensible to this. Cinebench is one example.

Come on now, it's not that bad unless you actually need 10+ cores...
Depending on pricing, I'm looking at the 7740k or the 7800x.

Jayz take on The Intel line up , I thought it was interesting and he brings in Amd's new 16 core 32 thread ,threadripper as well .

Skylake-X much faster than originally expected, will have 6C / 8C / 10C / 12C / 14C / 16C and 18C variants

Waiting to see the pricing, especially on the 7820x.

And I'll say it again: People are going to instantly complain that these CPUs will offer no tangible benefit in gaming the minute they get benchmarked. These CPUs serve limited purpose except to take away any momentum AMD may gain.

This must be true for the models with the highest core counts, which are focused for workstation applications. However, the 8-core model is going to be a serious choice for gaming. It has higher IPC than Skylake and the same single core turbo that the quad-core 7700k. It would play low-threaded games like the 7770k, whereas destroying it on well-threaded games.

Caveat: OC headroom. In that price range, OC is indeed a variable to consider. If the 8C variants OC poorly, then the 7700K might still be relevant for games even with a performance disadvantage.

Cheers!

Good point. SKL-X uses an improved 14nm+ process. I guess the new 8C model will get 4.7GHz on air without problems.

Looks like the final pricing is even better than I did heard.

Take this with a grain of salt, but it is coming from someone that I think is well-informed

CFL-S 6C/12T 350$
SKL-X 6C/12T ~440$
SKL-X 8C/16T ~620$
SKL-X 10C/20T ~1100$
SKL-X 12C/24T ~A lot

The change in the cache hierarchy alone produces 20% higher IPC in some benches.

 

[goldstone77]

It's exciting! I can't wait to see how the i9 and R9 measure up! Thank you AMD for giving us competition, so we won't have to buy the same CPU from Intel for the next 10 years!

 

[Phaaze88]

So it's down to the 7820x or 7800x. The 7740x and 7640x seem rather redundant, unless they don't burn up as easily as their little brothers do, and even then, the pricing(7700k & 7600k) may drop on them as well.

About overclocking, 10C SKL-X already hits 5.8GHz on LN2. For comparison 8C RyZen does 5.2GHz, whereas 8C BDW-E does 5.0GHz, both averages.
