2400g vs 6700k @ 4Ghz - Zen 2 for future comparison
 
I picked up a 2400g along with a Prime x470-Pro board to test performance and I'll also be picking up the next 4c/8t Zen 2 chip to compare it as well @ 4Ghz.

I split my current raid0 850 Evos and 32GB 3200Mhz G.Skill kit between the two and both are running fine with the XMP profile in dual channel of course. Both have the latest bios on the boards, fresh Windows 10 Pro install along with latest drivers. The 6700k is running using my loop, the 2400g is using a Wraith Max with a max temp of 67c(not throttling.) Aside from gaming let me know what you want me to compare before the Zen 2 release. I have both plugged into the iGPU for a fair comparison.

Rendering test:

Cinebench R20:

Ryzen 5 2400g average: 1971.3
Core i7 6700k average: 2133.7

Corona 1.3 Benchmark:

Core i7 6700k average: Time: 3:52 Rays/sec: 2,088,583.3
Ryzen 5 2400g average: Time: 4:19 Rays/sec: 1,869,559.2

Memory benchmark:

I am curious to know how the two compare for snappiness/responsiveness in applications. It's difficult to compare as it's subjective but I know you would do a good job of it.

1% and 0.1% would be much appreciated.

I'll have to test further but that's actually something I noticed right away that the Ryzen setup felt a bit sluggish when using the Windows GUI. It also took longer to install Windows even though I used the same model SSD and exact same flash drive and a USB 3.0 port on both. Browser and Handbrake felt the same.

I'm more interested in the Linux results once I finish these followed by macOS.

How much of a hit does disabling hyper threading cause? The latest research suggests that hyper threading needs to be turned off along with software mitigations to make a system fully immune so speculation attacks. Most of the guys with older computers are complaining that if they disable hyper threading the CPU doesn't handle multiple threads as well, which makes their old equipment unable to preform. Basically they have to upgrade.

Obviously if going the route of disabling Hyper Threading, the multi-threaded workloads will be even more impacted. I trust the sources I download my software from so I do not need to turn off hyper-threading. It's only those that don't trust the software mitigations that will disable HT. 8th and 9th gen already have hardware fixes for MDS.

Why CR2 on Intel and CR1 on AMD?

The Level 1 cache bandwidth is double that of Ryzen. Interesting.

That's the default that the AMD board set it to when using the XMP profile. I'll have to look at all the timings since the Intel system crashes when trying to run it at CR1. Curious if the Ryzen board sets one of the timings much looser than the Intel board.

Unfortunately, the same Hardware Fixes make these cpu more vulnerable to another type of exploit called - Fallout. It's never ending.
