14900 KS - the fastest Intel processor ever just launched

[BoggledBeagle]

Sorry for interrupting your lively discussion about heat, temperature and efficiency, but has anybody of you bought 14900KS yet?

I was planning to do so and compare 14900K and KS at fixed frequencies (5000/4000, 5200/4200, 5500/4400) and power limited to 120, 180 and 250W. All that with three different load intensities - 6, 16 and 32 threads of Cinebench.

I prepared tables for the measurements:



And then I cancelled my order.

Somebody from Techpowerup, who is paid for his work, should fill the numbers in this table... I would really like to see them.

Outside the United States, this CPU won't be available for at least a couple of months still. So no. But I've been asking the same question in general.

 

[BoggledBeagle]

They are/were available in Europe. Mine was ready for pick-up.

Well I didn't bring up the 7800X3D, kapone did. Look at the chart and decide for yourself how efficient these processors are.

It's perfectly possible to get good gaming performance when reducing power limits. You just have to set the voltage/frequency yourself and do a per core tune. Power limiting alone runs off the stock voltage frequency curve so it's not surprising lowering it reduces single core clocks.

How did I bring up the 7800X3D, when I was responding to your post about the 7800X3D?

I think this is a little outside the TPU wheelhouse. The reviews here are for the 'everyperson'. Default Windows settings, same RAM across platforms, etc.. That's not a bad thing as most people don't care to the level of interest displayed in this thread.

There's really nothing about a KS CPU that requires a review and a strategic buying process. You either want it or you don't. If you have a minimum improvement you need to see to decide, it's probably not for you. That doesn't even take into account sample to sample variance. Even at this level of binning, some will be better/worse than others.

Four posts before mine regarding 7800X3D, so you weren't the first to bring it up, but it's only being talked about as people are trying to say it's faster in games as a way to attack "the fastest CPU", when it's a toss up between the two, depending on the games you play and the resolution. I know for a fact that a 14900KS not limited by 6000 MT memory and an air cooler to make it an "all else equal" test bench against AMD can certainly stretch it's legs more.

No. I feel compelled to acknowledge that it's the fastest CPU in MT only, while its use case for a gaming only scenario is highly questionable due to its inefficiency and high price.


It's difficult to accomplish due to no clear definition on what "idle" really means.

A non-K CPU is different, because it's not an underclocked, undervolted version, just one with a lower power limit. At least my 11700 non-K is. The TPU review of the 14900K at various power limits is good for this.

Really? ~20% faster single threaded than the 7950X doesn't support that claim. Just because in singleplayer gaming the cache of the X3D brings the two brands neck and neck doesn't mean that the 14900KS isn't the fastest in both ST and MT, considering the cache really doesn't help much outside gaming. Hence "the fastest CPU". Even 13600K has faster ST performance than the 7950X. Stock 14900KS multicore of 42500 compared to 38000 isn't too shabby either.

1817 vs 2410 ST 7800X3D vs 14900KS, I hope the games where 3DVCache works are worth it if you want to cling to 7800X3D is the fastest. I know that mine doesn't always seem as fast as what other tuned Intel rigs can do in the multiplayer games I play, and I'm running a balls to the wall BCLK and RAM tune with the best ambient cooling money can buy. Of course, either is a fantastic gaming experience, but you're trying to claim that the 14900KS isn't the fastest in ST, and that's factually incorrect, by quite a margin.

Speaking as objectively as possible, every post you make is an attack on AMD chips. The Gaming benchmarks from the review show that it is the fastest Gaming CPU TPU has tested. Let's nor bring in the other X3D chips that have a 5.6+ Ghz boost on the non V cache cores for other tasks. No matter how you try to spin it the 14900KS is a waste for most applications. A max 500W power draw vs 90 or 108 is very glaring.

 

[kapone32]

Really? Is that why I use an AMD chip?

Perhaps you're just not used to hearing something other than "AMD is the best at everything". A shocking perspective I know. But then what I do is to focus on details and correct inaccuracies, both technical and lingual, and I do get a bit tired of seeing constant anti Intel sentiment that isn't even based on fact.

Every post you have made in this thread belies the general sentiment regarding the chip. You even argued with me that a 360 AIO could cool 500W just as good as 90W. You make claims like the 12 core chips are garbage because they "Only" have 6 cores. You tell me how slow my 7900X3D is when you have never used one. I see that you have a 7800X3D but it still does not take away from the fact that you bash AMD on a regular basis. It is to the point where ardent Intel users like your posts.

 

[KedsDead]

All you have to do is, take every time you said AMD and replace it with Intel. Then, replace Intel with AMD for each time you mentioned it.. viola, we have an argument that was exactly like it was 5 years go.

44 W (KS) vs 41 (7950X) or 17 (7800X3D) ST

374 W (KS) vs 254 W (7950X) vs 77 W (7800X3D) MT

Where is 500W? 90? 108? Oh, I see, you're comparing overclocked chips in synthetic multicore against stock chips in gaming, very fair.

I'm not arguing, it's a fact, despite your misquoting of "500 W". 14900KS with a 360 mm AIO gets 85 C stock at 376 W, 7950X hits 95 C even at less than half that wattage, since it's designed to boost till that temperature, and the IHS is crap.

 

[ThrashZone]

It has, but when every thread re intel gets posts that are it seems to me just an excuse to bash them, why post at all?

Hi,
If you have to ask that you haven't been paying very close attention hehe

This stuff goes both ways.

Intel fanism rejects out of box verses out of box differences so when this happens it's just circular bios edit blah.... my favorite response is repeating "Who runs default like that" and actually talks smack about reviewers running like that hehe

AMD wise they really don't have to go past this point because it's drop the mic time no matter what PL deduction a user of K or ks or HX chips can do not all of them can.

I just get a good laugh out of the whole back and forth tripping over their own bias perspective personally until I get tiered and ignore at least 2 of them so far hehe

How much power does a 7900X3D use. Or let's use a 7950X3D instead. Even if we just use Gaming the 14900KS uses way more power than any X3D chip. The world already knows that X3D chips are within 10% of non X3D chips at about 1/3 the power draw. When you talk about Gaming I see about 55-65 Watts CPU usage,

So? If you make a point please at least try and get your numbers right, or I'll have to correct you again.

Right now you're throwing "500 W" around because you saw it on a overclocked power limits removed chart somewhere, while directly comparing it to other numbers from a different test, as if that makes any sense or lends credence to your argument.

If you're asking what temperatures do 7900X3D/7950X3D hit under full multicore synthetic load, it's 89 C, since that's the X3D target as programmed by AMD. Still hotter than Intel at 376 W.

It's not a "10% performance difference for 1/3 the power draw" either. 7950X3D uses 140 W vs 7950X 254 W, for 35769 vs 38036 in Cinebench MT. So another number you've made up.

Noone is arguing that a KS doesn't use more power while gaming, it's the rest of the falsehoods being thrown around that are the issue.

And every post you make is righteous, divine judgment of Good (AMD) versus Evil (Intel/NVIDIA), this according to your own words. You'll never see eye to eye with each other for the same reason we don't see eye to eye most of the time, you have a quasi-religious attachment to AMD and you are not interested in the technicalities and details of each product, the fact that one is from AMD comes first and outweighs the rest.

Let me ask you. Has AMD ever had to pay a settlement to avoid a court case that would effect their share price? Is there any post that AMD is acting like a cartel in the GPU market? Have we seen AMD GPU partners leaving them for their tactics? Do we see that AMD reference cards are just as fast as AIB cards eating into their value? There is no denying the success of V cache in the DIY market and AMD have been dropping the mic on Intel for the last 4 years at least. I respond when people make claims about products they do not own. Just like how you tell me my 7900X3D/7900XT/MP700 PC is slow for 4K because you feel it will be. I could use Freesync and FSR as well but I will settle on Mantle to show AMD's dedication to the community.

What about AMD is worse than Intel in Gaming. We will watch the MSI Claw fail because it can't even keep up with a Steam Deck but people will go on.

For this specific thread people are defending the 14900KS when there really is nothing that makes it worth the cost vs a 14700K much less a 7800X3D for Gaming. I guess that is why dgianstefani talks about the 14900KS so admirably even though he owns a 7800X3D.

1. Yes https://www.theverge.com/circuitbre...ertising-class-action-lawsuit-bulldozer-chips
2. They don't have market share. They can't act like a cartel if they are losing on every segment.
3. MBA reference GPUs are always worse than their AIB counterparts
4. Again defending your PC when no one else brought it up
5. AMD's "dedication" is some dead API that was supported on a grand total of 5 games? Please.

Well i have 13700K and could easily buy the 14900KS (i know the right people ) but I won't buy the 14900KS because it's stupid and not worth the time to take out my 13700K and put the 14900KS in.

On my previous PC I upgraded 8700K to 9900K and that was worth it.

 

[BoggledBeagle]

I won't buy the 14900KS because it's stupid

It has 8 cores more than your current CPU, it is the best silicon for the LGA 1700 socket and is totally worth buying!!!

If I were you I would get it and downclock / power limit it to protect this precious chip.

Then you can fill-in the table I posted above...

 

[dgianstefani]

It's called not being biased or having insecurity over my personal purchase.

I'm able to admire the 14900KS because it's an impressive CPU. End of story.

Too bad I'm busy playing Helldivers 2, I can't have any down time for some insignificant upgrades .

Btw my pal with 14900K has constant crashing in Helldivers 2 with everything at stock, the fix was to disable turbo boost and run an all p-cores clock of 5.5ghz, the same clocks I run my 13700K at

See everybody?!

Even this normal 14900K could not work at its extreme stock frequencies, nobody can convince me the 14900KS is a TRULY viable and reliable product at its even more extreme speed.

My 14900K just wiggled its corner as an appreciation that I run it only at 5200 MHz.

If a CPU is having trouble at stock, it's defective and you should send it back, not run some half hearted underclock. The reality is more likely to be "I messed up the component choices/build/BIOS settings/software, and now my system is unstable".

I know which of those two scenarios (defective or user error) I'm more inclined to believe.

 

[BoggledBeagle]

If a CPU is having trouble at stock, it's defective ...

The manufacturing process Intel uses to make these products is not up to running at these extreme frequencies.

All these CPUs are ticking bombs, and they will explode sooner or later depending what conditions and load are they subjected to.

The frequencies I was proposing above for comparison of 14900K with 14900KS are not just accidental, I consider 5000/4000 MHz as safe frequencies for these CPUs, 5200/4200 should be still pretty safe and 5500/4400 is probably the absolute maximum, which most likely is not safe anymore.

 

[dgianstefani]

The manufacturing process Intel uses to make these products is not up to running at these extreme frequencies.

All these CPUs are time bombs, and they will explode sooner or later depending what conditions and load are they subjected to.

That's your opinion. The evidence of people running Raptor Lake silicon at high frequencies for the last two years would suggest otherwise, along with Intel's history of releasing products certified for ~20 years of use.
