What's lower and higher resolution in the context of your comment? Lower is 1080p and less higher is 2160p and up?

Based on that the performance differences with x265 and x264 become larger with the slower presets, not smaller.

Most likely due to better cpu utilization on slower presets.

Does anyone know more than just rumors regarding Zen2 APUs?
Will we get some before the end of the year?

I would really like to upgrade to Zen2, but I also like iGPUs, especially considering global system and idle efficiency.
It's hard to beat my i5-7500 in that regard.

The 3400G is a bit of a slap in the face to be honest...

The "3000" Zen+ APUs only released quite recently, so it will probably be quite a while.

Apus are always 1gen behind. You will have to wait for zen3 to gdy zen2 apu.

My hope was based on this:
https://wccftech.com/exclusive-amds-...nm-ryzen-apus/

If true, 7nm APUs could come earlier than their predecessors.
I just hope it's actually an AMD source and not just rumors...

Don't get your hopes up on so-called leaks from wccftech.
Look at their previous "leaks" from a supposed source inside AMD, majority has been proven quite wrong once the actual releases rolled around.

OK then... I'll try to live with the 7500 a year longer...

Wow - so the new Ryzen chips are faster than last year’s best Threadripper? Will have to keep an eye on this.

In general, the IPC of AMD's Ryzen 3000 series is higher even than latest Coffee Lake 9000 series from Intel after many, many years.

So, in order to find the fastest CPU you have to look at the number of threads utilized by the app (single threaded vs multi threaded) and the clock.

Generally speaking, Intel has still the clock advantage but AMD has both IPC and more threads than Intel.

x265 encoding runs a lot faster nowadays for Ryzen 3000 than Core 9000 at the same price:

Ryzen 3900X vs Core i9 9900K

It's relative to the number of cores in question, and the quality/speed tradeoffs as well. But yeah, HD versus UHD is a pretty good demarcation. The jump from 1080p to 2160p is a lot bigger than 720p to 1080p. And with HEVC WPP gives us parallelism proportional to frame height.

Ohh I am so excited about the new TR generation. If I get a 16c or 24c clocking with 4,3Ghz PBO that'll kick ass....

You have to wait for September for 16C and October for 24C/32C/48C/64C.

Isn't the 16C in September the 3950x, not a Threadripper II?

Yes, that will be a normal consumer chip with few PCIe and memory lanes.

But still has $300-400 motherboards.

But they do have PCIe 4.0.

Which I don't think is of much use for video encoding. However, there seems to be about a 10% performance hit using a X470 chipset mobo instead of a X570 for a new Ryzen 3xxx for video encoding.
