hey everyone,

i'm going to make my first build soon and have sort of settled on pairing the i3 6100 with an r9 280x, i was planning on going with a b150 motherboard which will allow me to install a second 280x in crossfire in a couple of years (when this one becomes too slow)

should i want to overclock the gpu (working with the base clock) i would have to invest in a z170 board and a better cpu cooler, in total this would be an extra 60-70 euros.

would that investment be worth it? considering my build? i'd be working with 1833 ddr3 ram.

already thanks for all your help,
kindest greetings,
monstreys

In a couple of years time, I very much doubt you will want to buy another GPU in SLi. By then, Nvidia and AMD will have both bought out a much faster GPU with twice the memory etc for less money, which will be even faster than 2 of your GPU in sli.

Buying a Skylake i3 is not a bad idea, but only if you plan to upgrade it to a Skylake i5 in a couple of years time (before intel change the socket again). Otherwise, if you can afford it, buy an i5 now - will last you years and years.

FX is simply not a good idea. Fallout 4 is a very demanding title, and the FX 9590 loses to an i3 6100. FX is old, and its age is showing. FX has been stagnant, while Intel keeps making minor improvements. Future titles being more multithreaded, is not going to magically make FX better, than i5. The cost to overclock an FX 8350, to match an FX 9590, would surpass the cost, of just getting the i5. Not to mention the more powerful PSU you would need, to handle it all.

Witcher 3 is pretty demanding. The 9590 does do better, vs i3, but still loses to an older locked ivy bridge i5.

Actually it is not, because it still wouldn't beat a stock i5, and would cost more.

Ddr3 1866 ram runs at too high of a voltage for skylake, nor are there many DDR3 capable Z170 boards. Skylake is better paired with DDR4.

hey everyone,

thanks for all your notes, for now i'm going to stick with the b150 (improved audio, sata express, m2) and keep the extra money in stock to invest in a newer gpu several years down the line, stock i3 will be good for now and in 2 or 3 years i might buy a secondhand i5 to install instead

Except you are not paying more for Intel. An i3 can keep up with, or even beat an FX 8350, while being a good deal less. FX 8350, with a proper board, and cooling, would cost as much, if not more than an i5, that doesn't need a more expensive board or cooling. Lower wattage/less expensive psu's can be used with Intel too.
 
Really? Let's try a little fact checking.


Not necessarily. A CPU offering more logical cores only helps if the game has been programmed to run on multiple threads. Just because a game is "multi-threaded" doesn't mean it will instantly use every core your CPU has available. A game that has only two threads is still multi-threaded. But that game won't care whether you've got four cores or eight, it still can't use them all. The vast majority of games now use four cores or less. So, considering Intel currently has better per-core performance, and considering that most games can only use up to four cores, why do you think a game will run better on four slower AMD cores than on four faster Intel cores? On games that can use more, yes an FX might have a little benefit, but let's explore that below.


Here we go, what you said you didn't actually say. You've said repeatedly that the 8350 is more powerful than a Skylake i5, though you didn't bother to quantify what that means. The only supporting evidence you gave is a Guru3D link and specifically the Espresso and Handbrake benchmarks. So, you're suggesting that because the 8350 beats an i5 in just one test ( since you haven't offered any other supporting points ), it must be a far more powerful CPU than the i5.

I suggest you look more closely at benchmarks before you provide them as support for your arguments. In the Espresso test, the 6600K loses to the 8350 by two seconds ( 47s to 49s ), but only when AVX acceleration is disabled. Turn on AVX and the i5 can do the task in 12 seconds The i5 actually beats every FX CPU on that list in the Handbrake portion. I'm unsure how you reason these results are evidence of the FX being "a way more powerful CPU" than a Skylake i5. The fact that a CPU with twice the cores as an i5 barely beats it in only one out of three tests suggests to me that the i5 has almost twice the efficiency per core of the 8350. So, even if it can't handle all eight threads of some extremely threaded game, it seems to me it can deal with each of those threads almost twice as fast as the 8350. So by juggling the threads around it could have almost the same overall performance.


Well I would hope so, because an OC'd 6300 platform costs more than a regular i3 platform.


Whew, I guess it's a good thing that the i3, i5, and most of Intel's CPUs are multi-threaded then, isn't it!

So, all in all, that's another big swing and a miss. Care to try for strike three?


Now then, we have rules here at TH. One of those rules is to not mislead other users asking for advice by giving them false information or presenting opinions as though they were fact. If you insist on making controversial statements, I suggest you back them up with supporting evidence ( the more sources the better, usually ). We enforce the rules here, so breaking them leads to consequences. And if you cannot understand what I have written here, I suggest you take a deep breath and read it more slowly.

You don't need a different board to overclokc the GPU. That can be done on all of em.

You won't be balke to OC the CPU. Also your CPU will be a noticeable bottleneck in the system from the beginning. I would invest the 60-70 euros in a basic i5 or go AMD with a fx-8350

Overclocking on non Z170 boards would disable hyperthreading (Unless it's that one H170 board from supermicro.)

Wouldn't beat a stock i5?
It depends,
Core i5 beats the FX 8350 in single threaded apps and gaming,
But in games that are optimized for more than 4 cores the FX 8350 will offer equal or better performance.
but the FX 8350 beats a stock i5 in multi threaded apps.

so a z170 board would be necessary anyway to get get full crossfire capability? i know it's always better to go with an upgrade bur if adding a second card would make it usable an extra year or so i'd maybe risk it... i'd only be adding the second card in one or two years anyway

since the price of the 8350 and the i5 are the same i would go for the i5 for sure... he can go for a 6300 which can be overclocked as hell...... my mistake for suggesting the 8350 and no most of the games doesnt need more than few cores so the i5 out performs it but in the future more cpu intensive games will require more cores and at that point the 8350 will out perform the i5 plus the 8350 can be overclocked a fare amount which will give it more performance.... if hes in a budget i suggest get a 6300k and a am3+

Even clocked to 4.6ghz, it lost in frame time, to the i3. When the i3 6100 was paired with faster memory, it beat the 4.6ghz FX. Crysis 3, is a multithreaded title. When first released, THG recommended an i7, to get the most out of it. Also most multiplayer games, are MMO's, which are notorious for being poorly threaded.
 


Again : all single player benchmarks

Single player doesn't mean it isn't a well threaded title, just as much as multiplayer doesn't mean it is well threaded. Crysis 3 and fallout 4 are single player, but well multithreaded. WoW is multiplayer, but is notorious for being poorly threaded, as are most MMO's. I do outdoor 40 vs 40 man pvp battles, quite regularly. World bosses can be tagged by as many people that show up to take it down.
 
The cpu work load in a multiplayer map is much higher . More threads will help , but total usable cpu horsepower is more important . And since an FX 8350 is more powerful than even a skylake i5 the i3's weaknesses appear .
Even an overclocked FX6300 will be better than an i3 in loads like that .

But would I build using FX cpu's at this point? Probably not . But you are not correct in making the kind of comparison you have since it is largely meaningless . Bad test = bad results
 


You are right . Multiplayer and multithread is not the same thing . But in those games that support multithreading then multi thread processors perform relatively better under a high multiplayer load.

As for the relative power of an FX 8350 I suggest you read this
http://www.guru3d.com/articles-pages/core-i5-6600k-processor-review-desktop-skylake.html
Note the heavy lift scenarios of encoding and transcoding .......................... and that the FX is usually beating even the skylake i5 .
When the software suits the FX it is still more than competitive
 

This. Apparently, most benchmarks, for most games (there are exceptions), show that those games are better-suited to higher per-core performance. Rendering and transcoding are not gaming. Rather than try to poke holes in data presented by others, I believe it would be more useful for you to present some data of your own.
