    I just want all 8 cores of my 3800x to do 4.5 at the same time.

  • comment-avatar

    feck ya Rob!

  • comment-avatar

    Ok. Technically, my 3700X not only reaches 4.4ghz as advertised, but it also goes up to 4.425Mhz with PBO enabled on a "just" 180€ motherboard, as MSI MPG Gaming Plus, which has a very decent VRAM and cooling structure on there. BUT I would love to see how does really affects that EXTRA boost on better MoBo of 200, 300 or 500€, because I haven't seen it yet, and would definitely confirm that AMD was true and rightful all the time. (at least to date)

    I bought a Ryzen 2600 2 weeks ago and it can do that too, is it because of a new driver update? it's really amazing how it can boost itself all the way up to 4.6Ghz with only 0,012 extra (1.412Ghz total)

  • comment-avatar

    that sounds really good but isn't that going to reduce CPU's lifespan? Also it would be wonderful to give that feature to ryzen 3

  • comment-avatar

    Hey look after the stock hz First im planting to buy the amd 3800x that have the stock mhz at 3,9 its only 700 mhz to 4,7 ghz so buy the highest stock hz to get there!

  • comment-avatar

    hi i just update new bios that release 9/18, i don't know why it's show 3.58Ghz now. it's 3700x

    Dear fellow Youtube watcher, please consider reporting this video for misleading information/fraud.

  • comment-avatar

    robert looks like Wallace lmao

    Well, this video is still bullshit – at least from @3:45 onwards

    sorry for being rude, but it is not was PBO obviously does

    Since AGESA 1.0.0.3 ABBA my 3700X can reach a 44x multiplicator on all cores at some point (mit 100 MHz BCLK that equals 4.4 GHz) – thx for that, great job – now finally my CPU works as printed on the box (~ 2,5 % higher scores in cinebench now, in gaming benchmarks ~ 0,5 % increase in framerates – acutally it was no big deal, but at least it works now

    BUT – if you enable PBO and tell it to overclock by 200 MHz (the maximum you can tell Ryzen Master or the BIOS at the moment) in theory the 3700X should be able to clock to 4.6 GHz (at some point on a single core) if Mr. Hallock here is right

    what PBO actually does with this settings is unclear, but it does allow the CPU to clock higher average clocks (like the first part of the video) – but it does not exceed the frequency printed on the box – it looks like it is just an "on demand allcore OC" (in my case to around 4,2 GHz my CPU consumes about 120 Watt instead of 90 Watt in a Cinebench R20 multicore load and i get about 3 to 3,5 % higher scores and the temps go up to 75-80°C – without PBO they stay at ~ 65-70°C – but on any singlecore load the multiplier does not exceed 44x nor does the frequency exceed 4400 MHz

    if you manually overclock the CPU on a single core it works just fine and is stable

    My results so far: (x570 AORUS Pro with Dark Rock Pro 3 – so no fancy stuff):

    at 4,6 GHz stable at ~ 68°C (Cinebench R20 single core score is 517 Points) above that, the CPU gets unstable

    So PBO would be worth switching on if it increased the multiplier of the fastest clock – in the current state it is just a waste of energy – you'll achieve more by raising BCLK a few MHz and overclock your memory and infinity fabric and let the default boost algorithm (thx again, it works) to the job it is designed to do

  • comment-avatar

    How is PBO different than Turbo-Boost? both seem to boost core frequency when needed and return to normal afterwards.

  • comment-avatar

    Don't really understand why this video is still up ????….. AMD please remove this video smh.

  • comment-avatar

    what about XFR2? does it stay the same as in gen 2?
    and are they both available only on b450 (or better) mobos and on the X models (eg. the 3600x and not the 3600)?

  • comment-avatar

    If the anticipated September 10th updates deliver anything near what this guy said he will likely get to keep his day job.

  • comment-avatar

    Ye, but in reality x570 + 3700x + best cooling solution + pbo enabled == 4.375ghz boost speed MAX. When 4.4 ghz is stated on the box specs. What overclocking are we talking about, mister?

  • comment-avatar

    I like AMD, but this is anti-marketing to itself, lol.

  • comment-avatar

    where is my 4.6 to my 3900x ???

  • comment-avatar

    I like what AMD has done with Zen 2, but this marketing and talk of clock is just fantasy. Most people struggle to hit advertised clocks and if there do it's usually very briefly. Just tell us what we realistically can expect to hit consistently and let the performance speak for itself.

    It's better to under promise and over-deliver than the other way around.

  • comment-avatar

    Bunch of marketing BS.

  • comment-avatar

    AMD, are you going to retract this video? This is blatant false advertising. The whole community is pissed off that you have lied about boost clocks. Zen2 CPUs struggle to reach their on-the-box stock clocks let alone 200mhz extra boost!! This is a complete lie! You should be ashamed. 👎

  • comment-avatar

    I came from intel and using 3900X now. It is an amazing chip out of the box. So, you tell me that i can even get better performance and what I need to do is just turning on the PB and the PBO, is that right? The question is how?

  • comment-avatar

    Gather round people and experience one of the most profound examples of marketing BS.

  • comment-avatar

    Mortar B450 not work the pbo with r3600….

  • comment-avatar

    Well i gotta say that this is so much of bullshit, asus x570 tuf / 3600x boosting only 4.25ghz/allcore 4100mhz , dont matter is pbo on or not, old defected normal 3600 was boosting only 4085mhz/ allcore 3998mhz.. so there is ALOT of extra on power and ALOT of extra on cooling(kraken x62@68c allcore test / single 48c).. i think i haven't even see the cpu taking 90w on pbo/auto oc on at allcore test…

  • comment-avatar

    so… B450 mainboard is dead for PBO..?
    I'm currently using 3600X + B450 Tomahawk, after enabling the PBO at BIOS, I don't notice any difference.
    PBO Enable or Not, The clock speed, always stays at 4.25GHz on gaming, nothing changes.

  • comment-avatar

    Well that was a f***king lie

  • comment-avatar

    This video is, at the moment, a complete lie. You're lucky to get the advertised boost clock on these CPUs right now. That's not to say they're bad, but it is disappointing to receive less performance than advertised, even if the difference is almost too small to notice.

  • comment-avatar

    This is just marketing BS.

  • comment-avatar

    In my experience my new 3700x does not even get to speeds displayed on the retail box. So this video to me is nothing but marketing BS.

  • comment-avatar

    The Ryzen3000 chips are awesome, I got one and it completly meets my expectations.
    However … this video is just false advertising. I guess it does more harm than good.

  • comment-avatar

    Well, this turned out to be entirely bullshit. Shame on AMD for misleading all of us. The chips are good, but this video is pure fantasy. I didn't need to be TRICKED into getting a new chip. This video just taught me that AMD will lie when there is a good enough marketing reason. Keeps me focused on reviews instead of believing the source so that's good I suppose.

  • comment-avatar

    I was really a fan of AMD, but after this charade I will think twice before buying a AMD product.

  • comment-avatar

    4.75ghz… Yeh… nice troll.

  • comment-avatar

    4.55??? 4.75??????????????
    Are you serious?
    Or in your dreams?

  • comment-avatar

    I did everything in bios and my 3600X will go as high as 4316ghz.
    I have Aorus X570 Elite + DarkRock4 CPU cooler + TridentZ Royal 3600mhz ram + 1TB Pcie 4.0 m.2 SSD inside be quite! Silent Base 601
    I know my build is nothing special but my choice in parts should not be consider weak sauce either.

  • comment-avatar

    i double dare you to do a live demonstration of this. it's marketing BS, the chips barely reach the printed on the box speed on a single core fore more then a split second forget about going above that speed even if your motherboard can deliver 4-5 times the power the chip can use.

  • comment-avatar

    Is this video a lie? no ryzen 3000 chip boost 200mhz higher than the advertized boost speed, they barely hit the advertized boost speed

  • comment-avatar

    Ok. PBO up to 4.7Ghz(with LN2)

  • comment-avatar

  • comment-avatar

    Does PBO still void warranty?

  • comment-avatar

    Why did you lie Robert? Your product is amazing. You're ahead in ipc, core counts, and far more flexible with upgrade paths.

    You didn't need to lie to us like this. This bad press just takes away from how great 3rd gen Ryzen is too. Which is sad, because it's an amazing product without the lies.

  • comment-avatar

    Is that why my 3900X on a X570 TAICHI per default is on 1,37V under all core load running into thermal issues(95C) after 5 mins blender render?

  • comment-avatar

    very impressed with his ability to write backwards and right to left.

  • comment-avatar

    Why the hell are you talking about something like PBO (Precision Boost Overdrive) which will automatically void your warranty if you implement it?

    Ever actually thought of telling people that you marketdroid cretin?

    You should look for a job at The Verge.
