Todaywe'regonnatalkspecificallyaboutbottlenecking, a topicwehaven't reallycoveredonthischannelinquite a longtime.

Andthenifyoudon't I don't knowwhatsuddenly a lighttodo.
I thinkyoucanplaywiththeratioandbringitdown.
I justdon't thinkyoucanoverclock.
Butanyway, thisisan 8700 K thatwhatwe'vedonesofar.
Asyoucansee, wehavetoact.
Ofcourse, becauseweturneditintobasically a 71 100 now, yes, I knowthecashvaluesaredifferent.
Yes, I knowthecashfrequencyandallthatstuffisdifferent.
ThisisnotintendedtobelikeHere's howperformanceson a 71 181 100 in 83.
Butthat's notwhatwe'redoingtoday.
We'reshowingyouexamples.
What?
But I'm likinglookslikein a realcasescenariowithrealgameandstuff.

Wealsohaveoursettingsthatsaidtohighestrightnow, whichiskindofunfairforthistest a littlebitbecauseofthefactthatifwereallywantedtosee a CPUboundtestwherewe'rebottlenecking, we'd wanttohavelesspostprocessingfiltersgoingandforhireframerates, whichwouldpushourCPUevenharder.

Sohere's whatwedid.
Weoverclockeditto 5.2 gigahertz, with a 50 ratioonthecash.
That's notsomethingthatexists.
It's notsomethingthatyoucaneventrytodowithyourown 8100 because a memberofthelochtoCPU.
Sothat's whyweuseSIpueslike 8700 k andthenno.
900 k todoouremulationoremulatingofothersipuesbecausewecantakeitanddialittowherewewanttoseewhattheoreticalperformances, likeatdifferentfrequenciesthatyoucouldn't otherwiseDubaijustpoppingin 8100.
Soalthoughthecashamountis a littlebitdifferent, I don't believethatisenoughdifferencebetweentheseapewstoinvalidateourtest.
Like I said, thestart, though, thisisalltheoreticaltoshowyouwhatbottleneckinglookslike.
Oneofthereasonswhywe'renotactuallydoinglike a 14 40 PierreFourcadetestisbecause, um, ifwe'retalkingaboutbottleneckingandthosethatarerunninglowNCpews, I thinkit's extremelyrarethatyou'regonnafindsomeonerunning a 71 100 orin 8100 with a four K panel, possibly a 14 40.

So I betyouanythingifwe'rein a 99 100 K oranotherCPUwithmorethreads, we'd probablyseeevenhire a P s withthesameGPsayswe'regoingtoNowwe'regonnapopin a 16 60 whichis a muchmoremidrangegraphicscardwiththesamelowNCpews, andwe'regonnaseeexactlyhowitcompared.

That's whywith 16 60 wesaw a very, verytightlineacrosstheboard, evenallthewaydowntothe 7 100 I wassurprisedthatwewereonly 63% GPUboundwiththe 16 60.
I thoughtitwasgonnabe a lothigher, whichgoestoshowthattheCPraceoverthelastseveralyearshasdefinitelymadeCPexperienceforgamers a wholelotbetterintermsofbottlenecking, becauseyouhavetotryprettyhard.
