Im starting to think that Sapphire Rapids is going to come too soon for me to want to upgrade. I said i was going to upgrade once it came out but i really dont think im going to want an upgrade that soon. I7 4790K is too stonk

    What do you know about Sapphire Rapids?  (Links would be fine too.)  I thought it might be the one after Tiger Lake, but idk.  (Also idk if it might be primarily a server architecture.)

     

     

     

    I'm still on the 4790K too.  I'm getting to where I'm wanting an upgrade soon, but no current products meet my needs at a price I'm willing to pay.  I'm tentatively planning to upgrade when DDR5 comes out.  But, I'm concerned that even with AMD's increased pace of innovation (99.999% not going Intel this time) the performance/price uplift will be nowhere near where I want before I upgrade.

     

     

     

     

    Benchmark example:

     

    Dad bought 286-10 system in Jan 1989.  Invoice didn't give CPU price separately, but online magazines say 287-10 (FPU but probably similar silicon) was around $280.

    Wikipedia's Instructions Per Second page says 286-12 was 1.28 MIPS.  (I'd estimate 286-10 ~ 1.0667 MIPS.)

    Dad got 486 DX4-120 CPU in Oct 1995 for $102.

    Wiki says DX4-100 was 70 MIPS.  (Guessing 486DX4 ~ 84 MIPS.)

     

     

    That's a 78.75x performance bump, and probably a 2.75x price drop, or about 216x boost in performance/price, in 6 years 9 months.

     

     

    I bought my 4790K in Jan 2015.  Six years nine months later would be Oct 2021....

     

     

     

     

    For a more real-world example:

     

    I ran a couple audio & video encoding tests on my 4790K several months ago.  Set up 2 hours of video & audio to transcode, did audio first then started on video but aborted a few weeks into the project.  (Yes, WEEKS!  I do have a gamer grade laptop I've been using as my daily driver, and yhe 4790K had sat unplugged for a year or so.)

     

    Video sources were all 4K 100mbps H.264 from my Panasonic FZ1000.

    In Handbrake, I was transcoding to H.265 / HEVC, keyint=1 (so all frames are keyframes making editing easier / finer, could cut/paste *anywhere*), q=0 (highest quality - Handbrake says q=0 is lossless when encoding H.264), and placebo setting.

     

    Audio sources were extracted tracks from the videos, converted to 48 kHz 16-bit stereo PCM Wave.

    I was using a multi-threaded front-end to LAME to encode to 320 kbps, stereo, 48 kHz, with checksums, etc.

     

     

    Transcoding the entire 2 hours of audio to mp3 took about 2 minutes.

     

    Transcoding just a single 4-minute video to H.265 took about ... 4 ... DAYS!

     

     

    I aborted the video encoding, as I said, after a few more had completed.  I didn't even get to one that was 15 minutes long, and ended up removing it from the audio encode queue.  This was due to the rest being 20 seconds to 4 minutes or so each, when the rest were done the 15-minute one was still encoding, and the multi-threading audio encoding was working only for multiple simultaneous encodes, not when there's only one active.  With the 15 minute file added I think it was taking about 4-5+ minutes for the audio encode.

     

     

     

    Anyway... I'd like something that at MINIMUM does that video encoding in real time (with a sub-$300 CPU, before considering GPU acceleration), and preferably as fast as my 4790K encodes mp3 (when it isn't choked by trying to encode one long file).

     

    My previous camera maxed out at 640x480, and I skipped over 1080p, jumping straight to 4K with the FZ1000.  I don't want to get a camera capable of 8K recording until a Celeron / Athlon could encode a 2 hour H.265 / HEVC video at max settings in under 2 minutes, or as fast as my 4790K was encoding those mp3s earlier.

    Dont know much about Saphire Rapids to be honest, but it seems to be coming up fast if you keep up with the tech news. I just remember seeing it on a roadmap placing it only a few years away recently which is way before i want an upgrade. Im sticking with my I7 4790K until it dies or i end up with a stack of money burning my pocket and a compelling platform comes around. Ryzen 3000 is awesome, but its really not Haswell and X570 is just straight up not as good as Z97 in my eyes.

     

    I have the cheapest Z97 motherboard i could find and have no issues with power components overheating, no issues with the chipset needing more cooling and any RAM i stick in it works well even at 5.1GHz 1.4V core. You just dont get that with more recent platforms it seems and thats not just belting on AMD, Intel are just as bad at this point and they have no value proposition at all.

     

    CPU power is also in no way moving as fast today as it did in the 80s and 90s, but finally its picking up the pace a bit with competition becoming a reality rather than a dream :D

    H.265/HEVC isn't mature enough for a decent shortness of time to encode yet IMO. H.264 is still the goto for a short encode time currently. - hardware accelerated I mean.
