This is not correct and I have to comment since it's coming from a mod on a respected website. You should know better. Or ask someone.
Single-thread performance will always be important. It's the foundation of computing.

The reason why today we see CPUs evolving more in core count than in per-core performance is very simple.
Having a multi-core CPU in a PC is a fairly young idea. They've only been around for ~15 years.
We're not saturated on the core count yet, so the easiest way to make a CPU faster today is by adding cores. But this won't last forever.

And of course we have technologies that will let us make CPUs running at 10GHz or safely operate well over 100*C.
But they are more expensive than adding cores, so they have to wait for their turn.

I further commented on what I meant by that.

The problem is that most cpu architectures name it x86, power pc, arm, ... all are hitting some kind of wall in single thread performance where all architectures perform about the same.

The differentiation is long ago outside of that single thread performance, its the number of cpu cores, power (consumption), features, integration (soc/accelerators/gpu/...), ...
It's already 2020.

The 10 series does look like a fun overclocking platform. I like that Intel is adding these nifty features like per-core HT toggling. Intel XTU being a requirement is a bummer as it is on Windows only.

I want to see the new XTU features in action for an overclock. I am curious on how many 'weak' or 'strong' cores are in the 10 core on average. Intel is giving us a lot more control and I like it.

I wonder what the intent behind per core HT is. I guess more options are always nice. I wonder if it will work like Renoir or the new Xbox where without HT a core can clock say 200-300MHz higher.

Some of the cores will clock higher and with less power draw when HT is disabled and you don't need it enabled for all tasks and on all cores at the same time.
Push your 6(example) fastest and "lowest power drawest" cores to the max without HT to run your game the best way possible,have all the others with HT on and clocked at stock to deal with your background crap.

Seriously, don't plan to use a CPU bought today for the next 10 years. Not with all the tech that we might see in this decade.

Oh i wouldn't use one myself for 10 years but i got a network of like 5 computers that gets parts rotated around when i do upgrades. In theory for basic browsing a 16 thread today should work fine. I mean in 2018 i used a Q6600 with a tape mod for a 3ghz chip in a Dell Oem and it worked just fine with a dedicated gpu and ssd. Some stuff was a tad bit slower but i wasn't pulling out my hair either. It was in the realm of good enough.

Many others in the thread Virtual Larry started about x58/C2D users still got their 10+ year old X58 rocking xeons EVEN still to this day. Sure its all dated but heck at least it is usable while a Pentium 4 barely was usable like 5 years out from its initial deployment? Computers today have a insanely larger shelf life then ever before.

I do stand by my comment about 10 years as a basic browser, for power users yeah we prob should rotate every other "generation" . I say generation like that cause well Intel isn't exactly doing generation jumps here. This is how little Intel has done since the 6000 series if anything to really demand upgrades unless you need threads.

No,just because there are benchmarks that have been "ported" to all the architectures and use the same amount of IPC in all versions doesn't mean that all architectures have hit the same wall.

As far as I've seen Intel has not confirmed that. It is purely reasonable speculation based on the fact that HT can be turned on/off per core.

Run some games on ultra others on medium others on high just to make your point look valid..the video.

They already have this(determining which core can clock highest with the least power) for X CPUs,
yes it's a guess but what else would it be?

Well i can't help their settings, i max out everything when i can. They aim for more cpu bottelenecked situations but refuse to drop below 1080p as 720p benchmarks will trigger most prob more then settings most may run on like lets say a 1060 6gb for example?. Also if you got a lesser gpu on a lesser cpu then those numbers could also help there if your questioning what should be upgraded before its the bottleneck. I had no agenda despite what ya may believe.

I love my 7700k for what it can do but if you watched the video nothing besides a 5.1ghz Intel screams upgrade to me when it comes to fps. I gain very little in most games with the 3900x but at least i gain threads. I need threads anyways and well those will keep a cpu going quite a bit longer.

if you got a issue with the benchmarks, you might wanna hit up Tech Jesus about that but honestly your the first one i prob ever seen dispute posted numbers from him. He is prob one of the top if not the best hardware reviewer i seen on youtube YET.

Even look at the 8c parts. Intel's 65w 8c parts have a 2.9GHz base clock. AMD's 8c 65w part has a 3.6Ghz clock. Stock-for-stock, the 3700X will deliver significantly higher sustained throughput with the factory HSF.
Intel's TDP =! AMD's TDP. And Zen 2's IPC advantage over Skylake is well in the margin of error (even the Stilt's extensive clock for clock ipc tests produced a virtual tie), and most likely due to reviewers bowing to pressure from rabid AMD fans insisting on Intel chips running at lower memory speeds, mitigation patches, and clock for clock ipc tests, all for that hollow "victory." This, when most DIYers, and especially gamers; heck, these same AMD fans download Ryzen DRAM Calculator the first chance they get. Point being, in the real world, gamers, and enthusiasts in general, hardly run anything at stock, and here, the Intel platform gains a lot more through RAM and CPU overclocking. The latter is virtually dead with Zen 2.


The use of "rabid AMD fans" is inflammatory,
and is no different than "fanboys". This type
of behavior is not allowed in the tech forums.

Thats true for the top 8-10 Core SKUs, but the 4-6 cores are not that much more power costly than the competition.
Also, I don't hear anyone talking about idle power consumption (where most systems spend their time until a task is being performed). The Zen 2 chips are mostly burning double the power at idle, while doing nothing, which in the long run could add up significantly.

I often wonder why this isn't brought up, i am not bugged by it but your right though. I can't defend this as a 3900x owner either. My tower really never does sit idle though as even when i go to bed the monitor is off and the 1080ti is folding. On my 7700k its loading upwards of like 19% at times just doing that. Obviously will be less when the 3900x is installed but its usually only pushing 1 good thread anyways.

I would ask why it idles higher but not wanting this to go off topic, maybe a good conversation for the 3000 builders thread in the cpu section? I would really like to see why and i would follow the conversation there.

Say what you want about IPC, it's close enough but I would give the edge to AMD as they can compete at a lower clock rate. But you cannot say that AMD is the same or less power efficient, that is just false. And it seems that is what you are implying with Intel TDP != AMD TDP. Unfortunately its hard to find benchmarks for non-k 65W Intel CPU's. And no reputable reviewer is going to bow to rabid fans. You can prefer Intel but don't try to twist facts.

strange everyone came to this thread to talk about how great amd is ;/

Not a whole lot else to talk about. @AtenRa is at least trying to be positive by mentioning the prices, but I'm not convinced that availability will be good enough for consumers to see prices like that. And these CPUs are so LATE. It's not a good look for Intel.

this is a anti intel thread you can say what ever you like! the last intel chips i bought are either xeon or sandybridge 3930k / 2500k/2600k of course you can use a cpu for 10 years ((switched to a 2700k and then to a 3600 amd in hopes of using less power)) now if we start needing to control robots or some strange task that requires a new awesome cpu in 5 years then sure you wont be able to use your 3900x hehe.

5-7% is not margin of error.

Clock-for-clock testing is flawed, we've gone over this multiple times in the past.
Point being, in the real world, gamers, and enthusiasts in general, hardly run anything at stock,
Gamers!=enthusiasts. If by enthusiasts you mean those who overclock anything at all, then they constitute an overwhelming minority and are not representative of the gamer demographic.

Can we please move past the "buying top-tier CPUs for longevity" discussion?

This is no longer the Sandy Bridge era, both vendors considerably improve their offerings every year, and today's $300+ CPU is very likely to be matched and/or beaten in one or two years by the $200 model. People looking to maximize value over time will buy according to their needs and upgrade more often, at equal or lower TCO. Buying a 12-core just for longevity is at best a low yield investment. It makes sense for top performance today, but that's it.



  • When it came out the, 3600 at $200 matched or beat the 2700(X) at $299/$329. The R5 4600 will make Zen1 look ancient.
  • When it comes out, i5 10600(KF) at $213/$237 will match the i7 8700K/9700K at ~ $380. The RKL-S will walk all over Skylake in the most important metrics for current Intel customers: ST and gaming performance, while later on Alder Lake will do at 100W what Skylake does at 250W.

Except we aren't.
We're making CPUs pretty much the same way we had been for decades - using silicon. That's what is hitting a wall.
But we've known alternative semiconductors for years. They're being developed mostly by research institutions, so it is a slow process. Once big enterprises take the leading role, we'll probably see some actual products.

It's not just about single-core performance either. Density is a real problem and we're already experiencing it.
Think about 3950X. It needs fairly robust cooling to stay under that 95*C limit.
Even if AMD can sell such a CPU for $150 in the future, it could never be accepted as a mainstream product, because there's no way to cool by the kind of cooling small OEM desktops offer.

But the solution is extremely simple. You make a similar CPU on a silicon that tolerates higher temperatures.
You end up with a CPU that still uses 100-150W, but with cores that don't mind 200*C. Hence, you don't need a 240mm AiO anymore. A decent slim air cooler will do.
The differentiation is long ago outside of that single thread performance, its the number of cpu cores, power (consumption), features, integration (soc/accelerators/gpu/...), ...
It's already 2020.
It's precisely 2020, not "already". As I said: at this moment improving CPUs by adding cores is cheaper and still makes sense.
That's because even with mixed, casual/work scenarios it's not that hard to benefit from 6-8 cores, and we've only getting to that in the mainstream segment.

But now, going to 12, 16, 64 cores etc - a lot of people won't see a significant improvement.
People who are dependent on single-thread loads will not accept being stuck in 2020. They'll gladly pay a premium to see some progress.

So who knows - maybe the CPU market will fork? We'll have CPUs with less but faster cores (probably very expensive at first) and CPUs with more but slower cores (probably the more "budget-friendly" option).

Maybe heterogenous processors are the answer. If I could choose between a 3950X and a "3700X with extra 2 cores hitting 8 GHz", I'd certainly take the latter. Even for the same cash.
This is no longer the Sandy Bridge era, both vendors considerably improve their offerings every year, and today's $300+ CPU is very likely to be matched and/or beaten in one or two years by the $200 model. People looking to maximize value over time will buy according to their needs and upgrade more often, at equal or lower TCO.
This only applies to DIY PCs (so like 5% of the market?).
For most consumers and companies a PC that is expected to last for as long as possible, with 4-5 years being a typical lower limit.
