Skylake-X review: Intel Core i9-7900X and the X299 platform

Introduction Intel's new X-Series consists of i5, i7, and reissued i9 processors, all of which require the same X299 chipset that comes with the LGA2066 socket. The S-series processors will continue to be used with the 200 chipset. In some applications and games, we've encountered performance trends that didn't match our expectations. Considering that Skylake X has a speed advantage due to higher clock speeds as well as new architectural... Intel has reduced the shared Last Level Cache (LLC-L3) and transferred it from an inclusive to a non-inclusive (but exclusive) approach. This was done with the help of an efficient caching algorithm that improves the hit rate of the L2 cache ... The Basin Falls X299 chipset The Kaby Lake-X and Skylake-X processors sit in an LGA2066 socket (R4), powered by an X299 chipset with 6 watts of power, underscoring Intel's strategy of using server chipsets for their HEDT- Li...

Grand Theft Auto V (DX11)

GTA V restores the old pecking order and also shows two things. First, it's still an Intel domain, but AMD has made up for it with the Ryzen CPUs! It's really amazing how you can increase so clearly with a little fine tuning even after the launch. Intel will probably have to follow suit with other applications.

If you look at the frametime variances and the Uneveness index, the Intel CPUs are far less ahead than the FPS figures initially suggest.

 

Hitman (DX12)

Exactly this assessment also applies to Hitman, because the FPS numbers are not everything:

With the frametime variances, the whole thing is a little bit relative again. The slowest in the field, the Ryzen 7 1800X, offers the most balanced result:

 

Shadow of Mordor (DX11)

There are also games where the CPU used is actually sausage. Of course, we don't want to leave out such classics, because often enough it almost doesn't matter what you screw under the graphics card as a subset.

The details also prove the relative tie of all test candidates:
