Single thread/IPC performance since Intel 8th gen?

[eddiew]

Hey folks,

Niche question, but does anyone have a good resource or even anecdotal evidence for how single threaded performance has changed over the past few years? I have an [email protected] (sort of; avx-workloads will down-clock to 4.6), and I've largely been assuming that it's not very far behind a 'modern' CPU on the ST front but... am I wrong?

Basically, I threw Cinebench r15 and r23 at it, and it's scoring like it's on stock clocks (!??), and it's significantly (40%) behind the ST scores of a stock 12th gen equivalent. Even 'just' a stock 5600X is ~30% ahead on the score board.

And it's not that I don't care about multi thread, but most of what I do responds to between 1 and 4 cores. I've been ignoring Ryzen because I didn't think it had anything to offer outside of "moar cores", but I am wondering if I'm actually just an ignorant fool who hasn't kept up with the times...

Thanks for any info!

That's a fair shout. Ran the CPU benchmark and got exactly the same score as an 8086k. Which turbos to 5ghz. Which is my overclock

Ok, well now I know what to look for in stock for stock comparisons Does look like new CPUs are a solid step up, actually. I might have to ponder this...

Roughly:

Good summary, tbh, thank you

So a Zen 3 core on a wide range of workloads should be about 35% faster than an Intel 8th gen core, which is inline with your observation.

Great to have it confirmed, thank you ^^

Well, I might end up considering a 12th gen i5 to replace this 8th gen i7 then... same core count, a lot more performance per core. Could hit the spot in a few places
