FX vs i5

[JNB]

At stock speeds what is faster an Intel core i5 3550 or an AMD FX 8150? Also what would be faster overclocked?

What do you intend to use the processor for? Gaming, video editing etc

 

[sarinaide]

Probably the i5, if you could notice it.

 

[jaguarskx]

Stock speed = i5
Overclocked = FX by a little bit (only the i5 "K" models can be OC'ed)

Gaming

 

[jaguarskx]

i5.

 

[SteelLAD]

If gaming then definitely the i5 all the way, demolishes the FX chips.

 

[iam2thecrowe]

for gaming? then even the i3 gives the fx 8 core a run for its money. Take any i5 SB/IB over any AMD chip for gaming.

 

[crisan_tiberiu]

in a "single threaded world" the intel arhitecture its the best. 99% of games are not multi core optimized

 

[JNB]

But what if i got the FX overclocked to 5ghz? What would be best for gaming then?

 

[rds1220]

Overclocked I5 vs an overclocked Bulldozer the I5 is still going to win out.

 

[JNB]

yeah but you can't overclock the i5 unless it is a K and a K is out of my budget, so would and overclocked FX beat the i5 at stock speeds in gaming?

 

[amuffin]

You wouldn't be able to reach 5ghz easily, regardless the i5 will outperform the overclocked bulldozer.

It's roughly 20% faster than a BD processor.

What made the FX processors so bad then?

No. In fact an FX 8120 at 4.2Ghz is equal to or even quite a bit less than an i3 2100 is gaming performance.

For gaming the best FX processor is the FX 4170. If you have to buy AMD you are better off with an old Phenom II X4 975-980 or a Thuban core X6 1090T-1100T.

The i5-2500k is only about $10 more than the 3550, you should grab that then.

That would take a page to explain. Here is a good article explaining it.

Well, Intel looks like the best way to go. Comparing the i5's would i notice a difference when gaming between the entry level i5 3450 @ 3.1GHz and the top end i5 3570k @ 3.4GHz?

 

[amuffin]

No.

 

[JNB]

I'll definitely settle on the 3450 now then, as it's £31 cheaper than the 3570k and £16 cheaper then the FX 8150. Thanks for all the input

 

[Deleted member 217926]

^ Agree. No.


But with the K model processor you can overclock to ~4.5Ghz with good air cooling and Sandy/Ivy Bridge CPUs at 4.5Ghz are amazingly fast. Hell they are fast at stock.

Well you pretty much already got your answer and that is no. Even when the Bulldozer is overclocked it will still get beaten out by a stock I5.

Bad time to be buying FX anyways, with Piledriver out in September. When making a choice on CPU its ultimately your needs, the FX is not the best CPU out but it is good enough to do everything at well above playable framerates. The better choice is a Intel I5, but if you are on a budget then a $160 8120 + 990fx combo will net you $100+ towards other components.

In your opinion then, would it be better to hold off the build of this PC to see what Piledriver is like? Also i was going to wait for the gtx 660 and use that or will a 7870 be better?

grab the i5!
