Benchmark CPU at same Frequency?

[MadSheep]

I'm currently on Sandy Bridge, 2600k, OC to 4.3G

I can't compare how well my CPU is doing against say....7700k because I can't figure out how much 7700k has improved on a clock by clock basis.

 

Please tell me if you know any sources out there that compared the perf between generations 

 

I think I'm suppose to look at IPC (Instructions per cycle), but this is a relative metric. I want to know how much faster will 7700k be say....running x264 encoding (without quick sync) at the same frequency as my 2600k. Are there any data out there?

There's two that I could find, at least for Skylake (you can bump up the performance by 10% and get an approximation for Kaby Lake)

actually not too bad for a sandy bridge chip, it will probably outperform an i5 7600k in some cases

Yeah, shows how much Intel has rested on their laurels over the last few generations of CPUs.

Laughing in 4770k and no reason to upgrade... (the 8700k does seem appealing though, but not for that price!).

yea because AMD hasnt bothered to to make a new architecture for 5 years

Dunno, if the 8700K costs $350 or less, it will be very appealing IMHO 

 

(Yes, I am planning on getting an 8700K)

I want it but it really comes down to reviews if I will be able to justify it.

If it will have 1% low better by about 20FPS+ than my OC 4770k then it will be very appealing.

I am not sure I follow...

I can't recommend Ryzen enough but it's not for my usage of PC.

I would definitely like the 8-core EPYC but that would be overkill for a home server.

i mean before ryzen and ryzen's singel threaded performance is also more comparable to something like a ivy bridge cpu

The FX single core was far behind Sandy and IvyBridge.

Ryzen is toe to toe with my 4770k on the same clocks in Cinebench.

Here are some Cinebench rankings. You have to do some searching to find your target CPUs at the clockspeed your looking for.

This is perfect! Thank you so much. So I guess my suspicion was true. Looking at this, we only see 15-20% perf increase over....6 generations? That's pretty sad.

I'm pretty sad. There is really no way up.

I hope Ryzen can be a wake up call. I'm seriously considering the 12core Ryzen because it's a good match for my workloads.

Those are also quite helpful. 

 

Man, this community is pretty resourceful and amazing. I really appreciate everyone's help.

I'd like to see similar comparisons done across more generations, including ...

 

4004 -> 4040 -> 8008 -> 8080 -> 8085 -> 8086 -> 286 -> 386 -> 486 -> Pentium -> Pentium II - > Pentium III -> Netburst -> Core -> Penryn -> Nehalem -> Westmere -> Sandy Bridge -> Ivy Bridge -> Haswell -> Haswell Refresh / Devil's Canyon -> Broadwell -> Skylake -> Kaby Lake -> Coffee Lake, and so on.

 

Of course you can't run ALL of those CPUs at the same clock speed (I'm sure 4004 won't run at 4.5 GHz even under LHe, nor does 8700K have the option to be underclocked to 740 kHz), so you'd have to group them somehow.

For example, you could probably group everything from Pentium III all the way up to Coffee Lake together, cause Pentium IIIs could natively hit 800 MHz, and CFL can be underclocked to 800 MHz.  Then, maybe do like 386 or 486 through P3 (underclocking the higher-clocked/newer CPUs), and so on back.  Then, on the borders between the groups, you run the same CPU at 2 clock speeds - for example Pentium III would run at 800 MHz and at, I'm guessing, 100 MHz (FSB speed).

 

 

P.S. I had a bunch of LTT tabs open in another window (and on my phone) and was going through deciding to take the time to reply to the ones I had planned to, just not gotten around to yet.  Some are older, although this one didn't yet have the message at the bottom saying this thread was quite old.
