Okay so I’m back.
Yes it did. And in fact for my use case difference between 12S+ variant fall as low as 8% which while still makes me a little bit salty, is still considerable improvement from claimed 15% drop indicated by benchmarks on website. That was TL;DR version, now into details:
I don’t think I’ll give more than minimal attention to CCR1009 performance in this comparison because it got so obliterated by both CCR2004’s that I didn’t even really feel like testing it beyon initial run.

Those are results well known to me, result that I have seen long before and results that were far from satisfying for me since my machines were always connected by 10G link. Yeah sure, CCR1009 was in fact able to hit 10G but it required using fastpath and that simply wasn’t an option in my setup. It’s 9000 jumbo result. With normal frames it barely exceeded 1G. It’s 100% single core use case and router was obviously hammered on single core to 100%. After that initial benchmark I copied core parts of config to CCR2004-12S+ and re-run the same tests with following result:

Which was quite okay but felt like device is on the edge and indeed CPU usage looked like this:
[lapsio@CCR2004SWAG] /ip/firewall/nat> /system/resource/cpu/print
Columns: CPU, LOAD, IRQ, DISK
# CPU LOAD IRQ DISK
0 cpu0 0% 0% 0%
1 cpu1 0% 0% 0%
2 cpu2 100% 100% 0%
3 cpu3 0% 0% 0%
So being kinda worried that CCR2004-PC would fall below 10G if CCR2004-12S+ barely reaches it, I proceeded to test CCR2004-PC

And I don’t f*cking get it. CPU load was also 99-100% but transfers were much more stable and higher despite lower CPU clocks. But that could be just result of PIPE thingy on 12S+ so I decided to go lower with MTU, to 1500:

Bruh.
After some digging around I realized that it’s most likely down to difference between RouterOS version. Both devices were with factory ROS version but since CCR2004-PC was much more recent, it had 7.12 while CCR2004-12+ had something like 7.5 or 7.8 I don’t remember. Anyhow - after upgrading both routers performance of CCR2004-12+ significantly improved. Results with 9k jumbo now were almost 1:1 the same as CCR2004-PC and 1500 frames results flipped:
CCR2004-12S+

So it seems that CCR2004-12S+ was quite quirky device that suffered some significant performance issues. Though I’m kind of sad that CCR2004-PC has lower performance with most recent ROS version and performs noticably worse than with factory image - I believe it may be just related to all-round performance rebalancing and optimizing more common use cases than mine.
Overall I’m observing 2.3 Gbps vs 2.5 Gbps difference between CCR2004-12S+ and CCR2004-PC which is not all that bad. It’d be cool if it was smaller difference but I guess it is what it is. It still obliterates CCR1009. So I guess I won’t be returning it after all. Instead I’m gonna proceed to cry why it’s not 2.5 Gbps in use case that isn’t even my actual use case because I apparently have 9k jumbo everywhere in network so… welp.
I honsetly thought it’s not gonna reach 10G in full software with no fasttrack or anything and I thought I’ll have to go for CCR2116. So it’s quite pleasant surprise. Now I’m gonna go for bunch of Intel E810 and pursue 100G in full software XD
