Why do they say intel's 8700k performs better in games than AMD's TR4 cpu's ?

Solution


As Matt notes, that has nothing to do with a bottleneck. There's something else going on in your rig, heat-wise. What are your temperatures like? If you have some combination of poor airflow, improperly installed cooler, and dust, it's possible that you're getting throttling at load. Because your CPU should *not* be causing a problem.

Games only take advantage of up to 2 cores (extremely rare cases up to 4). All the extra cores and lanes won't help a game that doesn't want to utilize more than it's designed to. Intel has better single core performance (frequency does not equal performance when comparing different brands) and more than enough cores for any game.

Workstation tasks (like rendering) split up the work across all available cores (if you set it up that way), which is why Threadripper is mainly a workstation CPU.

Your current processor isn't a bottleneck (it shouldn't be, my 4770k is maybe a 10% bottleneck for a 1080Ti according to several other threads and forums). As for the "game mode", it's probably a power saving feature that sets a few cores to boost higher and shuts down unnecessary cores that aren't being used (at least that's the best technical reasoning I can come up with, ask an AMD rep for the actual truth)... but I suspect marketing has a lot to do with it.

so your saying i should get the 8700k ? and totally forget about AMD and their TR4 ? mate ?

If I was only gaming, upgrading anyway, and had the budget: definitely. It's half the price and you won't be able to tell the difference. Though I can't imagine your current CPU being a bottleneck; it doesn't sound like you need to upgrade. Oh well, that's just my opinion.
 
Games only use 4 threads in rare cases ??

Maybe 2 years ago but absolutely not true today.

A quad core can hit 100% usage easily with a lot of new titles ,especially multi player stuff.
There's a reasom why both amd & intel have gone 6 core with their mainstream chips now.

But yeah I absolutely agree , the tr4 is not a gaming cpu in any way,shape or form.
The coffee lake i7 is way,way better for gaming.

No need, I was just curious. 6600k shouldn't bottleneck GTX 1080, but that also depends on the games.
Are you running with a single ram stick? Then it would be a ram bottleneck if you are.
 


Clearly some have not looked at Battlefield 1 benchmarks/cpu core scaling recently...

Saying the dual cores are adequate for today''s games is is so far off the mark, I...don't even know how to comment further. :)

TR4 scaling in games, however, is indeed horrendous, as the extra cores are not only not helpful, they are a hindrance.

Your exaggerating a bit (and missed the bit in parenthesis). Sure, I was a bit out of date with how many games take advantage of more than 2 cores. But the majority of games still don't use enough cores for you to be speechless. Give me a break, man (or woman). :p

In all seriousness, even if games take 4 cores, the 6600K should be plenty for now. And an upgrade to the coffee lake i5 or i7 is a better deal for gaming than the Threadripper CPU.

The difference is not that huge unless you are 100% gamer of old dx11 titles. Newer games and future apps will all utilize multiple cores and even multiple GPUs more efficiently. In that sense a future proof CPU is definitely not the 8700. AMD Ryzen 2700X seems to be the CPU that is best in all regards.

no my ram is dual channel . the bottleneck calculator on the web says the cpu is bottleneck to that gpu

WIth the onset of such reasonable pricing of the R5-1600 and i5-8400, I could never tell someone to intentionally purchase an i5-6600...(3 years ago, ...perhaps; 4c/4t designs,if not quite a laggard today, will be so this time next year.)

At least we do seemingly agree on...don't buy TR4 for gaming....! :)

the glowing MSI is my gpu , it's not much new , i bought it for the watercool . it's basically a 1080

All games are made for consoles (those that aren't are those that run on 2 cores)
Current gen of consoles( xbone/ps4 )have one completely free quad and one they have to share with the OS so most games run with 4 cores max,some with more but only a few.
Even if the next gen of consoles with more cores had come out a year ago the 4core would still be ok for the next 2-3 years because that's how long it takes for a shift to happen.
Just think about when the xbone/ps4 where first released and what year we have now where it's still just a few games that cause issues for a quad.
(because they a badly coded but anyway)
 
DSzymborski has asked essentially the really important question here.

While there are some titles that use more than 4 cores kaby/sky/coffee lake all have exactly the same ipc .

They are strong chips for gaming full stop.You'rs is overclockable & at 4.5ghz the core performance is so strong it goes a long way to alleviate any restrictions it has being a straight quad core.

Hot & noisy ?? Thats a cooling/airflow issue , nothing to do with being bottlenecked , stick a 8700k or a TR in there which both run hotter & require more power & you'll intensify any cooling issues not solve them.

Whats your case model ? What's your cpu cooler ? What case fans do you have fitted?
