i7-4790k vs i7-9700k How big is the difference?

[keavlar]

Hey all, 

 

So I am about to upgrade my PC parts, and decided to check the difference between the 2 CPU, and there are some points that make me wonder, how they benefit me. 

userbenchmark Comparison

 

cpubenchmark comparison

 

wikipedia Hyper-threading

 

But what I noticed is that the 9700k doesn't have Hyper-threading, which I wasn't able to understand to the end.

And I will be happy if someone will explain it in simple words.  

 

The base clock speed is 3.6 vs 4.0, how exactly it is noticeable.

Hyperthreading is scheduling to better utilize the cores. It's like using 2 hands to feed a mouth instead of 1 hand. 

 

What are you using the system for? You can look up cpu benchmarks for your usage whether it be for a particular application or game.

cant answer this without knowing your uses. From performance perspective, 8 core no HT performs like 6 core with HT. In other words, ignoring IPC gains, 50% faster clock for clock in all core workloads than your 4790k.

Well, mostly I game on the PC and browse.

Which games are you playing and what graphics card are you using? 

There are plenty of benchmarks online and likely of the games you're playing that compared performance with various cpus.

I'd probably just not do that upgrade. New Ryzen chips seem like a better buy but benchmarks and all that.

[GoldenLag]

Probably wait for Ryzen 3k instead.

 

The 4790k is good enough to hold on. Only the non-ht quadcores are starting to struggle a lot

Well, the specs are in my info. GTX 1070 msi gaming X  , + samsung m2 960 .

Games, not that big of a deal, PUBG, and maybe BF

Going to the 9700k isn't going to make much if a difference for gaming performance unless you're currently struggling to stream or otherwise multitask while gaming.

You can see how it compares to the stock 7700k which is a decent analog to an oc'ed 4790k.

Are you currently unsatisfied with the gaming performance?

Given how the 4790k performs in games, Id assume the 9700k will be a lot better. I didn't feel like getting on of the boards at the time and got an 8700k instead. It can actually keep up with a modern card with the current games even with bad optimization. 

[Epoxe]

Going from a 4770k to a 9900k while keeping my 1070gtx I didnt notice a huge increase in top end, but my lowest 1% fps went up dramatically making games feel much smoother. No regrets. (I use the CPU for more than gaming, hold onto your panties the bUt ThE 9900k iS StUPiD fOr GaMiNg lunatics lol)

Darn.. sorry for long delay. 

I am not that happy with some lag on PUBG, not sure which is slowing me done. MOnitor, GPU or something else. ANy way, upgrade is mainly done is to use old pcpart to build new for me mother. 

Instead of buying a new one.

Is it only PUBG? What kind of lag? Are you encountering stuttering?

I am not sure, It might be only a monitor. Or connection over internet. I mean server issues. 

Any way. 

Yesterday I was thinking to building a mew Pc, but this morning, I am again thinking about upgrading mine. 

I mean, in teh future, I will propab;y will upgrade my Pc eventually, so why not now, and that way I can use my spare parts, so to call

But need to decide on a better MB

Scratch that, I will build just a new pc for mother. I wont upgrade mines for now
