ICYMI, AMD Claims to have Caught Up with Core i9-12900K Gaming Performance Even Before Zen 4
The Ryzen 3000XT line of processors were the kind of stop-gap products that make people wary of stop-gap products, and AMD plans to remedy this. The new Ryzen 7 5800X3D is an upcoming Socket AM4 processor designed with the singular purpose of matching the Intel Core i9-12900K "Alder Lake" processor at gaming performance, so Intel doesn't have free reign until much later in the year, when AMD debuts "Zen 4" and AM5. It's also a means for AMD to signal consumers as well as investors to the sheer engineering depth the company enjoys these days.
The Ryzen 7 5800X3D isn't a a 5800X with an insane CPU overclock that throws efficiency out of the window. In fact, it has lower clocks! Instead, it leverages a new feature addition AMD did to its existing "Zen 3" microarchitecture, called 3D Vertical Cache. This is basically 64 MB of fast SRAM physically stacked on top of the CPU core die (CCD), giving it 96 MB of last-level cache. The company has already debuted this with its EPYC "Milan-X" enterprise processors, and the Ryzen 7 5800X3D would be the first client-segment product with this CCD.
With 3D Vertical Cache tech in place, "Zen 3" enjoys a gaming performance boost akin to a generational update, with AMD claiming anywhere between 10 to 40 percent gaming performance gains over the Ryzen 9 5900X despite four fewer cores; which helps it sneak behind the Core i9-12900K "Alder Lake-S," currently Intel's flagship desktop processor.
AMD CEO Dr Lisa Su was specific about who the 5800X3D was for—those who use their PCs for one thing only, gaming. The chip has 8 CPU cores, with SMT enabling 16 logical processors. Each of these has 512 KB of L2 cache, and share 96 MB of L3 cache. The processor ships with lower clock speeds than the 5800X, with a base frequency of 3.40 GHz (compared to 3.80 GHz of the 5800X); and boost frequency of 4.50 GHz (vs. 4.70 GHz of the 5800X). The processor's TDP is the same as the 5800X, at 105 W. As we mentioned, this isn't a case of the designers running the chip at eleventy GHz and several hundred Watts of TDP.
The 5800X3D, as a Socket AM4 part, is drop-in compatible with AMD 500-series and 400-series chipset motherboards, with a BIOS update. Since its TDP is unchanged at 105 W, it doesn't come with any special VRM requirements (at least nothing different from what the 5800X needs).
Intel has already reacted to this development, by announcing the Core i9-12900KS, a variant of the i9-12900K with a massive 5.50 GHz boost frequency for the P-cores, which it hopes will ward off the 5800X3D. Intel is missing the point here. The 5800X is a $400-something part, priced rivaling the i7-12700K, and while the pricing of the 5800X3D is unknown, it's highly likely to end up with an enormous gaming price-performance advantage over Intel. The 5800X3D releases this Spring.

I also do not understand why AMD would slow the CPU down so much, I guess heat from the cache, and it's not offset enough by the process shrink? That's simply squandering the advantage they have with the 3D cache, and will mean much lower performance with applications and games that do not benefit from more cache. I hope this is just some marketing or TDP thing, and that it can be overclocked by a few hundred MHz, at least!
If this really is it, then AMD could well have jumped the shark. I hope that AM5 has DDR4 support, then instead of this, I'll upgrade to that. If there's no DDR4 support on AM5, then I'll pick up a 5950x to upgrade my 3900x instead. No way am I loosing cores to one-up some overheating Intel CPU in 3 or 4 games, which I don't play anyway, and loose tonnes of performance at everything else.
Why would i be upset? you think i cry because AMD has come up with something to match ADL, grow up.
I don't give a crap what i use be it AMD or Intel, as i have stated umpteen times, the only reason i got the ADL board and CPU is because it was a gift, otherwise i would be still using the AMD rig i had. Unlike some morons, i am not loyal to either AMD or Intel, i am loyal to performance.
The reason it is a crutch is because AM4 will be using it. There was no reason to implement it on AM3 only to beat ADL in gaming, hence a crutch. I don't give a crap if you agree or not as it is my opinion.
Nothing is certain till there are CPU's in the hands of testers, people always hoot about this % increase or that, but it is piss in the wind till it is confirmed.
3d cache was not AMD's innovation, it was TSMC's, AMD are just using it that is all

Seriously why is everything coming from btarunr such garbage work?
Slapping a bunch of L3 on the die might be a costly way to add a tiny bit of performance, but for a niche market it might be worth it.It's a stop-gap solution. A lot of people are "needing" new computers before Zen4 arrives, and DDR5 availability is a huge problem for Alder Lake.
Intel does much much wider and more expensive R&D than AMD.
Not everyone is a native english speaker and not everyone understands slang terms.
Using this in an international environment is ridiculously stupid, especially when it's supposed to be a form of journalism.
When I'am on a foreign speaking site, I tend to go to Rome, and expect that it's not written for me, and that I may need to work some things out for myself.
Too bad TPU is using that as a guideline for what's normal. Very telling too ... I guess they like association with the sewers of the internet :confused:o_O
I mean you're on the internet. On a tech forum.
Surely just... google it?
What's the point? Being trendy and making people google?
LOL, just like the 3000XT models ended up with enormous price-perf advantages, right? Oh wait, those were overpriced lemons that only suckers and fanboys bought... AMD realised this, which is why they're only releasing a single model of this stop-gap rubbish, in limited quantities, priced through the roof, to separate more suckers and fanboys from their money.
I particularly like how the slides don't show the actual FPS numbers. They could be getting 1 FPS, at which point 1.4x FPS in Watch Dogs Legion seems a little less impressive. It's almost like they're hiding those numbers fro precisely that reason... but like I said, suckers and fanboys.ICYMI is internet slang that's entered the common vernacular, e.g. www.bbc.co.uk/news/av/world-59777677 - you're just an old man who's out of touch :p
AMD already did to get to 29% , 35/45 is just hype training the shituation.
I too expected a product line not a product, but this close to Am5 , I, and anyone like me were being naive.
AMD just needed a market awareness nudging campaign and price cuts in reality plus they Do want to sell the stock presently in the channel.
I don't see why so many people have issue with this. I'm older than most, I got my first computer in 1991. I don't use social media at all, I've never had a Facebook or Twitter account.
However google is very well known, it's quick and easily accessible. Pretty simple no matter what your native language. I assume the author is not native English.
You learn something new every day.
At the same time, its feedback on the author's style of writing.
As commonplace as it might be, its still feedback. The most important part of that feedback, I think, is that ICYMI adds literally zero to the content presented. After all if you DIDN't miss it, you won't be reading the article to begin with. And for everyone else... it strikes me as hipster speak that serves influencer clicks. I get that typical snowflake effect from it. Dunno why, is it because I'm old (35...:rockout: ) or because I'm still sane? Whatever, it just feels that way, and it clearly got in the way of directing the reader's attention to the content rather than the writing style. And apparently, I'm far from unique in feeling that way.
Another thought is that many things 'common' today are really not cool at all. And most do originate from the internet slang that develops in the gutter of social media. So again, I ask, is that what TPU wants to associate with? Do its users? The same BBC that copied it, is old media that happily copies every Twitter fart and Facebook trend to make news. :kookoo: All the while wondering why people have such short attention spans.
My point being... let's apply some critical thinking over what we so shamelessly copy 'because people do it', and whether it actually serves a purpose or is just there so you can be part of the flock.
But it's a dead horse we're beating here so that's all I wanted to add.
