Project CARS & Far Cry Primal
Project CARS is a CPU-intensive title that promotes parallelism by breaking tasks into smaller chunks and spreading them among available cores.
Intel's high IPC throughput is clearly a factor as the Core i7-7700K and i9-7900X cruise to a substantial lead.
Ryzen Threadripper 1920X offers higher clock rates than then 1950X, which helps it secure a narrow victory.
The Core i7-7820X suffers due to its comparatively low core count.
Far Cry Primal
Threadripper 1920X shines when we overclock it. Notably, the chip yields a 14.9ms 99th percentile measurement, while the overclocked -7900X registers a much higher 18.2ms.
The Core i7-7700K suffers several extreme frame time outliers.

Judging from Threadripper 1950X versus the Threadripper 1900X we can infer that a difference of 400 megahertz is worth the tdp of 16 whole threads.
I never realized HT / SMT was that efficient or is AMD holding something back with the Threadripper 1900x?
I think the better question is, "Where is AMD going from here?"
The first revision Socket SP3r2/TR4 mobos are simply amazing, and AMD has traditionally maintained (and improved!) their high-end stuff. I can't wait to see how they use those 4094 landings and massive bandwidth over the next few years. The next iteration of the 'Ripper already has me salivating :ouch:
I'll take 4X Summit Ridge 'glued' together, please !!
"We maintained a 4.1 GHz overclock"
Per chart "Threadripper 1920X - Boost Frequency (GHz) 4.0 (4.2 XFR)"
So you couldn't get the XFR to 4.2?
If I understand correctly manually overclocking disables XFR.
So your chip was just a lotto loser at 4.1 or am I missing something?
EDIT: Oh, you mean 4.1 All core OC I bet.
A big die shrink like that would be helpful but I think that Ryzen suffers from other architectural limitations.
Ryzen has a clock speed ceiling of roughly 4.2Ghz. It's difficult to get it past there regardless of your cooling method.
Also, Ryzen experiences nasty latency when data is being shared over the Infinity Fabric. Highly threaded work loads are being artificially limited when passing between dies.
Lastly, the Ryzen's IPC lags behind Intel's a little bit. Coupled with the relatively low clock speed ceiling, Ryzen isn't the most ideal CPU for gaming (it holds up well in higher resolutions to be fair).
Threadripper and Ryzen only look as good as they do because Intel hasn't focused on improving their desktop chips in the last few years. Imagine if Ivy Bridge wasn't a minor upgrade. If Haswell, Broadwell, Skylake, and Kabylake weren't tiny 5% improvements. What if Skylake X wasn't a concentrated fiery inferno? Zen wouldn't be a big deal if all of Intel's latest chips were as impressive as the Core 2 Duo was back in 2006.
AMD has done an amazing job transitioning from crappy Bulldozer to Zen. They're in a position to really put the hurt on Intel but they can't lose the momentum they've built. If AMD were to address all of these problems in their next architecture update, they would really have a monster on their hands.
At 1440p and 2160p the gaming performances is the same, however your multi-threading performances are still better than the overprices Intel chips.
