They should be also compared with their previous models (1600,2600, or 1800X and 2700x) so that we can see the improvements.
I bet is better then what Intel had between its generations.
The CPU-Z look fake that look at 3 in 3600
Ok, so 9900K at 5Ghz gets ~6000 points with 3200Mhz memory. This AMD 3800X sample (w/ memory at 2133Mhz), gets 5406 points at 4.5Ghz. If we raise the AMD at 5Ghz, we would get ~6000 points. So, even with handicapped memory it gets the same IPC as Coffee Lake. In the end I expect to see 5-10% better IPC, which is nice to see from AMD. Still, Intel is launching Ice Lake in June, which uses Sunny Cove core that will have 18% more IPC compared to Coffee Lake. So we're back to AMD having 10% IPC deficit compared to Intel.
The only luck that AMD has now is that Intel cannot manufacture Ice Lake for desktop at high speeds.
Are you sure? All I've seen is Intel saying 18% IPC over SKYLAKE for sunny cove, ie over 3 year old hardware... AMD are saying 15% IPC improvement for zen2 over zen+Quote:

Also, there is a geekbench score for Ice Lake and from the looks of it, it has quite a bit more performance per core compared to Zen 2. https://www.reddit.com/r/Amd/comments/c2hhev/ice_lake_vs_zen_2_ipc_in_geekbench_4/
Let's look at that. Intel are launching thin/mobile chips on Ice lake. These aren't going to compete with the 3800X in the slightest.Quote:

So yeah, well done Intel.
If you would had the patience to read till the end I said: "The only luck that AMD has now is that Intel cannot manufacture Ice Lake for desktop at high speeds."
Also, the difference between Skylake and Coffee Lake is close to null (only bigger L3 cache). Lets not get over ourselves thinking Intel has slept during all these years. They worked on new architectures, also a totally new uArch. Sure, I admire AMD for what they achieved. I hope they will spank Intel hard. But don't you ever think Intel is will leave IPC leadership to AMD.
All in all, the paradigm is shifting from single core to many cores. So, I guess AMD will have a big advantage a few years thanks to the bet that they have done with using chiplets.
Intel isn't bringing the Sunny Cove microarchitecture to the desktop in 2019. From the outside it's impossible to know why: they might not have good enough yields on 10nm to do high core counts, they might be having trouble reaching high clock speeds, or they may just be limited by current production capacity at 10nm and chose to prioritize new laptop chips first.
AMD, in contrast, chose to prioritize desktop and server in 2019. Laptops are just getting a shrink of the existing APUs to the 12nm process rather than 14nm.
Intel has not yet announced when desktops and servers will get the new microarchitecture and/or the 10nm process. But rest assured that it will happen. Meanwhile AMD will work on further microarchitecture improvements and will probably bring Zen 2 to laptops in 2020. So this story is far from over.
