I used to tune ram with PiMod to gather efficiency. Each iteration goal was to be as near exact same time as the previous. And back then essentially on DDR2 systems PiMod was heavy enough to call the ram tuning pretty stable if it passed.Speaking of RAM the dynamic memory frequency tuning looks like a neat way to tune performance and efficiency further.
20% extra performance for 200% extra power draw seems absurdly stupid, but unfortunately the manufacturers find this totally OK and ship the CPUs with these settings! And all that in a general movement towards energy savings, global warming mitigation and enviroment protection...Just for comparison, my ryzen 7900 gets around 18000 points in cinebench at 44Watts. At stock 65Watts its 24000 points and 30000 points at 180Watts (on 15C-20C ambient). Imo its like exponentially increasing waste of electricity so it's wiser to lower performance a bit during gaming to achieve much better energy consumption.
You can simply tune the RAM timings to regain the lost 5-10 FPS with only 1-2 Watts extra on RAM.

I am afraid that memory timings tuning is a matter of the most serious PC enthusiasts, for example I am a technical enthusiast but in computers I never reached that level. So I will gladly accept the small drop in performance and not bother with this mysterious stuff...

14900K has a chance to be a better quality silicon than 14700K and for given frequency it can require lower voltage, and thus to be more energy efficient.

A bigger silicon is always easier to tune for efficiency. A smaller silicon (edit: from the same architecture), on the other hand, doesn't have to be tuned, and is way cheaper, too.Well, 14700K certainly it a better value for money than 14900K, and very good value for a 20 core CPU generally.

I am not sure if you are speaking about 14700K, because it in terms of inefficiency out of the box is nearly as bad as 14900K.A smaller silicon (edit: from the same architecture), on the other hand, doesn't have to be tuned, and is way cheaper, too.
These "slow cores" provide a majority of multithread performance and when the CPU is power limited contribute greatly to its mutithread performance efficiency.I don't see 14900K or 14700K as a 28 and 20 core count CPUs really. They have 8 powerful cores and a bunch of slow ones.

If I needed multithreadded performance along with top tier gaming performance I would buy 7950X3D or Zen 5 in a few months. I wouldn't need a 360 AIO either and I would be able to use a newer AM5 chip in a few years too.I am not sure if you are speaking about 14700K, because it in terms of inefficiency out of the box is nearly as bad as 14900K.
These "slow cores" provide a majority of multithread performance and when the CPU is power limited contribute greatly to its mutithread performance efficiency.
They concluded that with given silicon area 8P+16E config has better multithread performance than 12 P cores alone. That is all.And I can see you bought into the marketing by stating 14700K as a 20 core CPU when in reality it's 8 cores + a bunch of cinebench cores
...
An Intel CPU with true 16C/32T would probably eat 700-800 watts.
This is why Arrow Lake and 20A/18A process is going to be a very important node for Intel. ... If they pull this off in 2024, they will be on par with TSMC. Lets hope Meteor Lake and Arrow Lake will be good.

Monolithic chip with 16 P cores would be probably pretty large and expensive for consumer PCs. Such chip would draw only as much power as you would allow it to.
I am curious who will win the 1 thread perfomance race: Arrow lake or Zen 5?
Single thread performance don't matter much anymore. AMD won gaming by increasing cache while lowering clocks and gamers should look into a balance here. 7800X3D beats 14900K in gaming with 1/3 the power usage and ~1 GHz lower clockspeeds.
Intel now has 3 different cores in Meteor lake, new are 2 small cores hidden in IO tile which can handle some system and low performance tasks as video playback. Really smart IMO.Having a fixed number of IDENTICAL CORES is the best thing for DESKTOP. Software can then use whatever and perform as expected.

Huh? You are mixing 2 things together. General performance and performance of a specialised CPU for gaming. Single thread performance is the most important thing, everything depends on that.

Probably because a single low power cpu core can do the job drawing less power than most if not any gpu can. I'd love to see some numbers on that though.I don't see why that is smart, my GPU handles video playback
Single thread is not really the most important thing these days. Most apps and games are multithreadded at this point

If you mean video playback, any Intel iGPU or Nvidia GPU (or even AMD up to RDNA 2) can do that with much less power than a CPU.Probably because a single low power cpu core can do the job drawing less power than most if not any gpu can. I'd love to see some numbers on that though.

7800X3D has the lowest clock of all newer CPUs and still wins in most games because of cache, but yeah a few games tends to prefer high clockspeeds, not alot thoProbably because a single low power cpu core can do the job drawing less power than most if not any gpu can. I'd love to see some numbers on that though.
Single thread is still a very relevant metric, while a lot of games can make use of multiple cores, single thread performance often dictates fps cap.
Beagle is right though, the 14700 might be 99 of the 14900, but better binned silicon means a slightly higher clock or slightly less voltage for the same one which is a win.
What I'd like to know is where does the efficiency peak at now and have we gotten the best fps/w moved further up the clock speed. We've talked about 14900K metrics being good (thirsty untuned), but does a given wattage cap (say 65 or 95) give better fps than the 12900/13900 (if you attempt to ignore ipc)

Didn't you read above?Where???
Are you suggesting reviews should be done without XMP? That would be silly right?"My 14900K will draw less power if I disable hyper-threading" is about as smart as "my body will require less food if I cut off both of my legs". If you buy a $600 CPU only to immediately disable half of its features just to get acceptable power draw, you're not being smart - you are, in fact, being the exact opposite.
I'm getting really tired of seeing these "Intel CPUs can be power efficient too" threads/posts. Nobody cares that they can be, the point is that, at stock, they are not. The fact that it's possible to make these CPUs consume sane amounts of power is not the saving grace that everyone who uses them seems to think it is. If it's not good out of the box, i.e. how the vast majority of users will experience it because most users don't tweak CPU power consumption, it's not good period.
Funny enough, he's not. Intel is dropping HT for 'rentable units' as early as the next generation of Intel CPUs.I too can make random shit up.

XMP is another bucket of worms. If the compatibility is poor the user experience may be riddled with problems (hello AM4, not sure about modern Intel).Are you suggesting reviews should be done without XMP? That would be silly right?
Someone should, in particular the vendors producing the product. Out of the box experience effects brand reputation so someone should care or your going to lose money to a competitor.Nobody cares about what majority of people will do.
Reviewers typically ignore non-K CPU's. When making a purchasing decision for building your own PC are you more likely to go with a product nobody is providing feedback for?If majority of people care about efficiency then they shouldn't buy a K cpu and run it out of the box, that would be idiotic. There are non k and T versions - the most efficient CPUs on planet Earth, buy those instead.
