yesterday it was "all reviews no stock" and now it's "all stock no reviews"
i don't say this lightly; please take your meds
>the 7900X3D and the 7950X3D are the same CPU
moron alert
open up wide retard
>youtube "review"
I mean an in depth technical review by the likes of TechpowerUp, not some fat retard spouting his opinion for zoomers
not even worth a (You).
based
steve seems really lazy to me for only testing with 4-6 outdated/irrelevant games. at least other youtubers make the effort to bench 10-40 newer games
they should at least replace rainbow 6 and cs:go at this point
No. Who gives a fuck about benchmarks in trash like cyberpunk or goywards. People actually play siego and cs:go compared to them it's basically a synthetic benchmark. If you feel like playing any of them just save your moneyand drink some extra corn syrup, it's the same
Can you point to a time where TechpowerUp has significantly differed in conclusions to GamersNexus?
>conclusions are all that matter, I like my reviews in 30 seconds or less.

nice projection homosexual retard
Most YouTube reviewers are shit but Gamers Nexus is actually good. This guy knows how to test.
>in-depth review
>does not do micro ops level benchmarking
?????????
100% of benchmarking for cpu are worthless heaps of trash, they does not compare microcode implementations (cycles, latency, branch prediction, etc), who the fuck care about cinebench or whatever else trash? you already know cpu hierarchy from specsheets...
I learn more about a gen from official dev guides and guides for compiler people, same for gpu and most of hardware.
How is this vs a 13900K?
Go for the 13900.
Look at this chart.
what the fuck its nearly 6000 better!
ordering now
wait for the Xeon w9-3495X instead, its 79595 bigger than the 13900k
did you have this ready or did you make it on the spot?
it's over
factually bulletproof

You want to give $700 to a company but they won't take it, another great launch from AMTurd
>""12"" cores
>actually 6 cores when xbox game bar detects a game
The fact they need xbox game bar to park the cores is hilarious, fuck AMD.
Why is it hilarious
>I'm retarded
oh, sorry
>I don't know what I'm talking about so I'll just proceed with insults
What the fuck did I say that was wrong you absolute mongaloid? Why the fuck should your CPU need some 3rd party intrusive software to park your cores? Kill yourself.
Game bar is not a 3rd party software, it is literally part of the Windows OS by default.
It is no different than how Microsoft had to make updates to Windows to support scheduling for Alder Lake, except now you get more control as a user.
>Windows OS
Ah yes, AMD's first party operating system Windows
lol
>AMD's first party operating system Windows
correct, it is the primary target platform
you think CPU and chipset support in Windows is all Microsoft’s doing?
They fact that Intel needs a BIOS hotkey to disable cuck cores is hilarious, fuck Intel.
>They fact
I accept your concession.
this. what the fuck AMD I dont want any microsoft spyware on my PC
>you need xbox game bar installed even if you don't need it
>if it doesn't detect your game, or it mistakenly detects some other app as a game, you can lose a lot of performance
>you can't use X3D chips for gaming on Linux without a massive performance drop
this looks like a future nightmare having to check which cores are being used for every program, game and general use.
I'm sticking with intel
Intel also has issues with big and little cores. Scheduling is already a nightmare.
AMD
>will this thread run better on a core with a lot of cache, or on a core with higher frequency?
Intel
>will this thread run better on a P core where it may only get half due to HT, or will it run better on a slower E core but exclusively?
I want to go back
Intel's approach is very simple unlike amd's whitelisting approach
>P-core if program is in foreground (high priority)
>E-core otherwise
I think Intel are better at answering that question than AMD.
For Intel there is a clear hierarchy of performance. Dedicated P core > E core with dedicated L2 > E core with shared L2 > P core hyperthread in nearly any application. It gets more complicated when thermal and power constraints enter the picture, but the thread director can provide the utilisation metrics needed for those granular scheduling decisions.
For AMD an application may perform better on v cache or may perform better with better frequencies. Additionally there's inter-CCD latency. And I don't know how AMD is able to monitor the runtime utilisation of each core for making more granular scheduling decisions.
It's much more complicated irl because not all threads are created equal. Like in that second picture T1 and T2 are put on dedicated P-cores, but then they start waiting on I/O and doing nothing while T3 and T4 do some work, so the scheduler has to shuffle them, and then T1 and T2 return to work so they have to be put back, all of which produces overhead and cache misses, which the scheduler also has to take into account when deciding how often it wants to shuffle threads.
The key difference to AMD here is that the scheduler at least can have most of the information required to make decisions, while with the half-X3D chips there is no way for it to know which thread will benefit from extra cache (even if developers somehow test their software and provide that info, that'll only work for the current amount of V-cache and behave unpredictably if cache tiles of different capacity are introduced)
>buy an expensive 16-core CPU thinking you can do a lot of shit in parallel
>run video encoding on half the cores
>run game
>xbox game bar sees game, shuts down half the cores
>both your encoding and your game run slow
7900X3d is same but it's only 6 cores
I thought this was deboonked. The "parking" of the non-3D-cache CCD just basically means they don't do anything if they aren't needed, but on a modern system that's basically never going to be true and effectively it's just "hey these whitelisted games have priority on these 3D cache cores".
It has, he's just a retard who can't read.
>what is taskset
>you can't use any chips for gaming on Linux without a massive performance drop
FTFY. You're welcome.
good day gentleman
It's a weird in-between product. 7950X3D and 7800X3D both get a full 8C CCX with the extra cache, 7900X3D only gets 6C with extra cache.
This is a lie, you can set it in BIOS to always prefer the cache chiplet and it works without needing any special software in the OS. Applies to Windows as well, of course.
There's an option to manually override game detection on a per-program basis if a game is not identified automatically.
>you can set it in BIOS to always prefer the cache chiplet
Yeah I sure love to either reboot every time I switch from games to using other software, or lose a double digit percentage of performance.
>parks the cores so game is forced onto 3Dv cores, other cores are allowed to wake as required
reading comprehension is hard.
>Here's your E cores bro.
>reading comprehension
it is when you dont understand that the scheduler is getting it wrong and thinking games are programs
>"thread scheduler kills the 6 other cores"
>"no, that's wrong"
>"well thread scheduler doesn't perfectly identify games 3 days after release"
give the goalposts back jamal.
like I said, reading comprehension.
I'm not taking about games scheduling.
re-read the posts slowly and you'll get there.
this is who I was replying to, both mentioned game bar and how it detects games. are you sure I'm replying to you? are you a schizo?
>AMD paper launch
AMD know its a mistake, thats why.
if you're spending $600+ on a CPU you'll get a 7950 or 7950X3D
if you're a gamyer you'll get a 7800X3D.
the 7900X3D has no market whatsoever
People screeched at them to make all 3 happen, AMD obliged and people are whining that they did.
Can't win either way.
maybe people wouldn't be so mad if amd had set expectations right before the parts launched
their pr and marketing departments are pretty bad at doing their jobs
And what expectations did they mismanage?
Their PR graphs were more or less on point with testing so far.
You know, actually communicating how the scheduling is done and what to expect to see while using the processor
Like how intel actually did demoes about their thread director during their announcement/launch events.
People asked for cache on both CCDs
those caches would have to be seperate per CCD and the windows core schedueler would need to force threads to specific CCDs for them to be useful. How long did it microsoft take to fix the other simple task to not spread all threads among all CCDs but to leave space for one to turbo boost? 2 years? It makes no sense for AMD to deliver an expensive hardware feature that microsoft will not enable for years.
Which would make no sense for desktop market. I'm honestly surprised that AMD even bother with doing dual-CCDs. I thought they were going to just pull a 7700X3D (6-core) and 7800X3D (8-core) and call it a day.
>People screeched at them to make all 3 happen
Did they really? Or did they ask for more X3D version? Or just only X3D cpus?
People are screeching because they literally half-assed it.
AMD couldn't handle the idea of being spanked in pure 1T shit so they made the CPUs worse for the people who actually wanted the cache.
The 7900X3D could have been interesting because it's only 6 cores sharing all that L3 cache rather than 8
But it seems it didn't matter that much
>The 7900X3D has no market whatsoever
People desperate for V-cache but don't to pay scalpers prices 7950X3D and 7800X3D which are both going to near-unobtainum for most of 2023. 7950X3D is already being scalped north of $1K.
>7950X3D is already being scalped north of $1K.
Makes me said this is where we are at with the DIY PC market.
Sad part is it seems like mobo companies are beginning to understand what they can get away with when you have so many retards buying off emotion.
im going to wait until 7800X3D reaches 300 euros and build a new pc
am4 still works fine and everything its overpriced
I’ll still get a Threadripper PRO, with real 24 cores, all the same, and 8 memory channels and 128 pcie lanes. For me only the best
so the 7800XD only has 8 cores with cache so it cant be a victim of this scheduling horror show?
That's right. All cores are created equal on 7800x3d.
Yeah.
it's 12cores in dual ccx and only six have 3dcache.
no buy
Always
Mad
Decisions
Why did they only put cache on one CCD?
Does a fifth chiplet really make so much production cost difference on a $700+ CPU?

>7900x3d review
that was hard
youtube reviews are by unqualified gamers for zoomers with ADHD, not real reviews.
Just stick to the two Steves and, if he happens to cover your topic, Buildzoid.
if a review isn't 20 pages long, takes an hour to read and goes into exhaustive painstaking detail about features that I dont even understand, then it isn't a review at all.
This, but unironically.
I forgot to mention, I’m autistic and trans as well, if that’s relevant.
I'm autistic too. Not trans so far but growth mindset!
it's just not an interesting part
either wait for 7950x to be in stock or 7800x3d
Should I get a 7900X3D or a 7950X
7950x
productivity will be better and gaming will probably be about the same
7800X3D for gaming, 7950X if you render and shit. The X3D really fixes shitty optimized games.
>0 reviews
AMD didn't sample them because they're mediocre value, aside from the shitshow that is Xbox bullshit and it needing to park cores. Really dumb product. At this point I'm not hyped for the lowest end variant, with the crappy clock speeds but we'll see. At least the top end is the best gaming chip now.
I don't think you understand what "park" cores means, it just means they won't be used unless required.
> 7900X3D
I wouldn't even torrent that crap if it was possible.
When will AMD make cpus with v cache on both CCDs?
Never will happen. If you more cache across CCDs, you are going have go with Epycs/Threadripper Pros.
Pluton smells like rotten corpse.
Imagine seeing shit like this in the windows kernel
if (ApplicationName == "BF5.exe") {
CoreMask = CCD_1_ONLY;
} else if (ApplicationName == "gta6.exe") {
CoreMask = CCD_1 | CCD_2;
} else if (...) {
...
}
what? why
When will intel make their own version of V-cache?
shittiest cpu ever
2 ccd, only one is vcache, both are not 8 core
Sounds like the 8350 all over again. They haven't learned squat.
Why would anyone care about the higher end variants
only the 8 core one matters for gamers
Because we are in a market where people just have to have the highest end shit even if it's meaningless.
Actually, like that the 5800X3D was the only 3D cache CPU as it singled out the consumerist gaymer idiots who had to make the decision between the actually good CPU for gayming and the highest-end CPU.
