Replace my i5 2500k 4.5 Ghz for i7 7700K or wait ?

jasonsony735 · 12 Jul 2017 at 15:10

Its going to cost me £600 to upgrade to a new CPU and Board & Memory ! Is it worth the upgrade ? As I believe at best all i am going to get is maybe 20 FPS boost on my games.

More info required..

Do you only game on your PC
What types of Games do you play?
Do you Alt tab a lot between Game and Browser and do you have a lot of tabs open?
Do you Stream while you play?
Do you use only 1 monitor?
You have a 2500k, i assume you will not be upgrading for a good while after this upgrade?
What GPU are you using?

I went from an i5-760 @ 3.8 to a Ryzen 1700 @ 3.7 and it gives me much higher and more stable frame rates in BF4 & BF1. Kept the same RX480 GPU. I now get normally get 120-144fps in BF1 when before it was around 50-70fps depending on how much was going on , on screen and which 64 player map I was playing on.

It really depends what you are trying to achieve. More modern games make use of extra cores, older games may not.

Pointless going for 4 cores these days, the next 12 months onwards will have developers using more than 4 cores in development. AMD have sent out hundreds of developer kits to push multi core use. Look to the future and get 6 core if yo'ure going to get anything.

For longevity and to save £140 and get yourself a Ryzen 1600.

Easy.
R7 1700 goes for ~£280-285 (comes with good cooler supporting OC also to ~3.9Ghz, if you try to keep the voltage low).
Asus Strixx B350 (very good B350 board) less than £120

Check here for RAM the latest file
https://www.asus.com/uk/Motherboards/ROG-STRIX-B350-F-GAMING/HelpDesk_QVL/

You need minimum 3200Mhz DDR4 to get most of the Ryzen CPUs. Anything less and you cut from the performance due to the way the Infinity Fabric works.
So according to the file
GALAXY HOF4CALCS3600K17LD162C (16 GB)
or
CORSAIR CMK16GX4M2B3600C18

However if you want to fiddle with settings for higher speeds, make sure you get Samsung-B die ram.

EDIT: MSI B350 Tomahawk, is a great board also, with much much bigger RAM support at 3200Mhz+
https://www.msi.com/Motherboard/support/B350-TOMAHAWK.html#down-manual

Ofc you can go for X370 board, and my personal choice could be Gigabyte K7 (~£200) or MSI Titanium (£250)

If you are playing games then the 7700K is still king and will be for years to come.

GAC · 12 Jul 2017 at 19:38

id honestly have a butcher of a few review sites for comparisons to what your get between your current cpu and the others but honestly unless i was seeing a huge gain i wouldn't change and just hold on to your coins until the next gen of gpu's hit where cpu's will be more useful and hopefully games use more cores.

wouldnt do anything at the moment wait till august/september time.

IvanDobskey · 13 Jul 2017 at 07:14

I went from 2500k to a 6700k and it's definitely more consistent FPS when gaming. Very few dips now.

It's not night and day better, but I'm happy enough with the upgrade.

worth a read ! I got more then the average 15FPS found here for yours but mine was an i7 860

More to the point of this thread...

2500K @ 4.5Ghz vs 1700X @ 3.9Ghz: the 1700X is a whopping 60% faster.

No 1600X OC result but given that 6 core scores identical to the 8 core 1700X at the same Mhz the 1600 @ 3.9Ghz will score the same as the 1700X.

The 7700K (7740X) @ 5.1Ghz is only a few % faster... for £140 more money.

The Ryzen 1600 is the one to go for.

Edit: TPU..... similar results even with 2400Mhz RAM.

No point upgrading from one Intel quad to another. For £600 you really should be looking at a AM4 8 core system.

greatash · 13 Jul 2017 at 16:34

Bad time to upgrade to a quad core, especially when they are just about reaching end of life after years of Intel domination.

Ryzen is a good upgrade path or wait for coffeelake if you really want Intel since they are replacing mainstream i5/i7s with 6 cores.

DONOHUE07 · 13 Jul 2017 at 18:26

Honestly don't know why anyone would buy Intel at the moment, from 1400 all the way to 1700x AMD is the way to go.

Not said that that for many years!

Actually given the perf shown for the Ryzen 9 1920X & 1950X today, AMD all way to 16 core CPUs

Intel has nothing to compare it for perf/price

In addition

Ofc OC 1700 is much much better value for same perf.

Ooh havnt seen this, thanks for Sharing. My guess is these chips are going to go for silly money? £700+ plus?

jigger · 13 Jul 2017 at 23:46

About £50 per core it seems.

We shall see for the Threadripper series.
Atm we know that the 1920X 12core will go for $799, and the 1950X $999 (top of the range) 16 core 32 thread with XFR @ 4Ghz.
But there are another 6 CPUs missing from the lineup. 3 between 1920X and 1950X and 3 between 1800X and 1920X.

Apparently the 1920X is faster than the 7900X. And the 1950X just leaves the rest eating dirt.

Check after 1:20

EDIT: Guru3d added the AMD benchmarks on their charts just to show some indication what we have here. We do not know RAM speeds though, so results could improve significantly.

I've done some more tests myself : Example Witcher 3 4K Max on my system I got a constant Max 70 FPS and LOW 58 and that is on i5 2500k at 4.5 ghz - From that result I will not be paying £600 to upgrade just yet for 5 or 10 FPS gain. ! No point.
