4770k and Looking for a new CPU

1) When will a new CPU be avail to replace the 4770k that is at least 50% faster?

2) Same question but 100% faster?

3) What is the expected performance increase that can be expected if spending $300 on a new CPU?

CPU performance updates seem to be so dreadfully slow over the past few years...

Each generation is about 7-10% faster, so you've got a while to wait.

Even longer to wait.

Your CPU is the best you can do for your platform, unless you also want to buy a new motherboard and RAM.

It's been roughly a 7-10% increase each generation after Sandy Bridge was released in 2011.
 
Yeah I don't expect to see 100% CPU performance over my i5-4670 anytime soon myself. Now that said we might get 100% in overall computer performance by building an entire new rig. But even that could just be a maybe at best.
 
Just buy a new CPU around when the new consoles come out (2020). Even if the single thread isn't much more than a 4.8 4770K the extra cores and fast DDR4/DDR5 would come in handy.
 
Thanks guy... Yes I have an SSD and a 970 GTX... My rig's primary function is for flight simulation so a strong CPU is as advantageous as a good video card...

I will probably build a whole new rig when the next gen video cards hit the "Ti" series (about 1 year from now, I think)... New CPU, etc for a dedicated VR machine... I usually get the best CPU I can for ~$300 each time I build and no more than $500 for a video card but it seems the cards have risen more than the CPUs relatively speaking (and not just because of mining). Most of the flight sims don't really take advantage of multi-threading but when I build the next rig, I'll bias more towards that as long as the single core performance is not sacrificed much...
 
Your best bet is a 5 GHz 8700k/8086k. That with DDR4 3200+ will provide a noticeable boost.
 
Well... I could go as early as this fall but probably will be Fall of 2019. That said, will a 100% be possible by then?

What defines the 7-10% per "generation"... As in i7 generations? Looks like 4770K is a Haswell 4th gen and now Intel is at a Coffelake 8th gen so maybe 40% boost over what I have now... That's pretty good I guess... Seems like new gen about every 9 mos on avg?
 
Flight simulators are extremely dependent on high clock speeds and core IPC. An 8700K should be a large boost for you over a 4770K.

I would be very surprised if a 8700K would be anywhere close to 40% faster than a 4770K for your flight sim performance, unless it also happens to be massively multi-threaded, which, as you say, it isn't.

At most, we're looking at a 10-20% improvement and that is due to a combination of higher IPC, clockspeeds and memory bandwith.

Note that we are only essentially looking at one generation of IPC improvements because the 6th, 7th and 8th gen chips are actually all based on the same architecture, the main difference is that the 8th gen has up to 6 cores.
 
Wow... So maybe by next build if I wait to Nov 2019, I might see a 40-50% improvement on CPU? I remember those heady days of the 8086 to 80386 jump... Now that was really awesome...
 
It all depends on whether you overclock your 4770K. What speeds are you running it at? The 8700K turbo's to 4.7GHz and overclocks easily.
 
8700K has 50% more threads and higher clocks, so in multi-threaded stuff, 50% faster than 4770K is probably in the ball park.
Single thread, 20% or so.
 
It also depends i would think on the resolution you run you sims at, 1080p or 1440p or higher. Also if your screen can do more than 60fps. Because let's say you get 90 fps with your 4770k/970gtx on a 60 fps screen, even if you get a better cpu that runs 120 fps, you won't see a difference at all.

The 8700K is clocked around 7% higher than your current CPU and is approximately 5% faster per clock in most legacy code. Truth be told, we may never see a 40-50% improvement in single-threaded performance over what you have, aside from with dedicated instruction sets or baring some major breakthrough in material science. Clockspeed improvements are diminishing and IPC has hit a wall with current architectures.

If the next generation of flight sims are better threaded it will be a different story. Since hitting a wall, AMD and Intel are adding more cores instead.

in what specific task(s)?

because i think thread ripper might have the first two covered.

i know, you're probably inferring intel, but i couldn't help being "that guy"
 
What else do you do on the PC ? If your main concern is games, I need you to relax and take a deep breath. Your current CPU hopefully OCed is just fine for games. You need a video card upgrade if you want to enjoy games at high resolution and high graphics settings and AA and FXAA and what not. Look my CPU takes 7 percent of its power to run Unreal Tournament Alpha which IMO is the best engine the thickest engine,, not just textures thrown around. This is the only game I play and I get 60fps @ 1920x1200 high settings and 16x CSAA and vsyncOn and all that jazz. Today's games barely use a Thread or two out of the 8 that you have on your CPU. maybe 1 or maximum 3 worst case 4 threads is what todays games demand. You have that covered. Now if you tell me you do 3D modeling, and CAD, and Video Editing 2 hour films or DAW or rendering of any kind then you can upgrade your CPU. If it's for games, then your waisting your time.

Nearly every game I play loves hyperthreading, and can utilize more than 8 cores. Without hyperthreading, I cannot get 180 fps on my 180hz in the FPS I play the most.

The only games I play that are single threaded bound are DX9 titles.

Yeah man, just stick with the 4770k at least until DDR4 prices return to a sane level. Hardware Unboxed tested the 4770K v. 8700K in a good variety of games, and concluded it is a waste of money to upgrade unless already determined to spend on a high end card.
