He is comparing coffee lake vs skylake-x, not skylake-x vs skylake-x refresh. The coffee lake chips do over clock better than skylake-x even with a delid. I have not seen any 7820x or 9800x reach 5 GhZ for daily use. While there are tons of 9900ks hitting over 5 GhZ.

I have a x299 and a z390 system. Gave the wife the x299 for her business and built the z390 for myself. My x299 consists of a 4.8ghz 7820x with cache overclocked at 3.2. the ram is running at a tuned 3600mhzcl15 with tight secondaries, as this is key for the mesh architecture. It is also delidded. My z390 is running a 9900k at 5.1 GhZ with a ringbus set to 4.7. the ram is running at an XMP profile of 3400mhzcl16 I set the 9900k stock and compared both rigs with a 2080ti. The 9900k was around 5-12% faster at resolutions of 1440p to 4k depending on the game. The 9900k also ran cooler stock. But what I noticed recently, using battlefield v with HDR and RTX on, the 9900k was almost 20% faster. I have no explanation for this, other than ray tracing requiring much better single core performance (it also trounced my buddies 2700x). But for your use cases, I would go with the x299 setup with fast ram and tight timings.

My guess is the HDR models will be around 1500 compared to the 1300 of today's models. HDR is worth it when it works, when I gamestream to my HDR tv it's night and day compared to sdr. I bought one of the first gsync monitors from Asus when they launched, spent 1k on it as a guinea pig. I have never regretted my decision until playing in a UW. Might as well be a guinea pig with the new models.

Was watching widescreen monitor reviews today after trying a friend's lg widescreen monitor (I can't look at my 1440p 16:9 g sync monitor in the same way anymore). Does anyone have any official dates for the new Asus and acer HDR versions besides q4 2018? Or should I just get the z35p, anyone with experience with it can chime in? Checked out this review and it looks great:

1) sucks for all those people who bought a 488gtb instead of a zr1, think about the money they could of saved..... 2)tons of people buy modified cpus from silicon lottery, they are binned and delidded with not much of an extra cost added onto the cpu. I don't see how this proves how bad basin falls is. 3)TLbleed only impacts you if your PC is already compromised. I am willing to bet AMD is impacted in some way as well....oh did you forget this: https://www.cnet.com/news/amd-has-a-spectre-meltdown-like-security-flaw-of-its-own/

1) Money is not always a factor, many people want the best and are willing to pay. 2) I already mentioned if he does not want to overclock get a 8700k 3) My own experience with my 7820x was an example to prove the potential of Skylake-X. I was willing to pay for the best 8 core possible, so I bought it already delidded from silicon lottery, that came with their warranty. Forget about the 1900x, my 8 core can can hold its own in MT applications against a 1920x and smoke it in single core applications and that is a 12 core cpu.

Tons of misinformation about x299 performance in this thread. Simple question if your not overclocking, get a 8700k. Money aside, if you want to overclock, this includes getting a good set of memory and tweaking memory sub timings, then you will love any x299 cpu. The Skylake-X cpus have the same issue as ryzen in terms of memory latency. By getting fast memory and tuning for the lowest latency possible out of em, you will see huge gains in games.

This video (hardware unbox in general) completely misrepresented x299. The platform today is much more stable, if you can manage the heat, it overclocks extremely well. With a little tweaking (especially for the 8 cores or more chips) the performance in games can hang with a oc 8700k and smoke ryzen.

Install the 4000 MHz ram then test your latency with aida64, if you get under 60ns your golden, if not begin tweaking. Also make sure your mesh min and max ratio are at 32/32. Also I noticed with Intel Turbo core 3.0 while it will boost 2 cores to 4.5, it does not boost the rest of the cores over 4.0 for an ample amount of time. Since I am overclocked I deactived the tool on my PC.

The 7740x does not use mesh core connectivity. Its a higher clocked 7700k on a bigger die.

Can't emphasis this enough, skylake-x is very sensitive to ram due to the mesh structure of interconnected cores. The bios update will help, 0802 (September) is your best bet from Asus, but with ram speeds of 2166/2666 you will most likely not beat your 5820k. The initial tests of skylake-x had it behind in some games compared to Broadwell-E and to some extent haswell-e in certain games. But after the x299 mess was sorted out, it is now quicker than last gen extreme processors in majority of scenarios (take a look at digital foundries test of x299) at stock clocks, and blows past them when both are overclocked. Update your bios and set your xmp profile to at least have the ram run at 2666, then re-test. The gap will close, but the ram is still too slow.

Garbage for gaming Skylake-X I noticed my GPU clocks at 4K are much lower than 1080P, with the exact same temps. Need to figure this out as i think i can hit 4800 at 4K.

The main issue is your ram speed and latency and you may be phantom throttling. If you do not want to play with the bios/update ram I would advise to return the x299 stuff and get a 8700k. The x299 platform needs to be played with to get its full potential, while z370 is just install and go.

And here is the full Reddit thread:

Fix your ram issue, update your bios, and if u don't want to overclock the cpu, at least overclock your mesh. Below is a 7900x@4.8, with different combo of ram and mesh oc
