I7 vs I5 for next Gen Gaming

[Kuzma]

When you code for 8 APU-Like Cores, we're having a total different conversation.

 

I think HT will be a bigger deal from now on.

just got a i5-4670k and are tinking in getting a intel 6/8 core in maybe 1,5 years - 2 years (if they exist by then)

[Demonking]

Get a I5 3570K or a I5 4670K if you have the budget if not get a FX 8320 i do not recommend a 8350 its the sames as the 8320 just over clock it to 4ghz & save 50$.

You know, the FX-8350 can overclock too  Crank it up to 4.6 or 4.8 if you like, most can do that if I remember correctly....

I thought that wasn't the case as much anymore with their 5ghz CPU's

i7 doesn't have any more cores than an i5 (LGA 1150 SKUs anyway).

It has more threads which r like cores, theoretical cores

I'm gonna be "that guy" and just leave this here for everyone that just TL:DR'd Glenwing's post on the last page about hyperthreading.

Hyperthreading is NOT more cores.  Current games do not take advantage of hyperthreading.  Future games MAY take advantage of hyperthreading, however that is hard to say because most of the talk as of late seems to be about games optimizing for cores, not threads.  An i7 is a good investment if you are running programs that will benefit from hyperthreading such as (much of) the adobe suite, and other professional software.  For gaming, an i5 is all you could possibly need.  They are extremely powerful and capable.  I don't have much experience with AMD's cpus (with the exception of their APUs) so i don't really have much to say about them, however, im sure they are perfectly capable. 

 

TD:DR - if youre building this rig just game game on, an i5 is all you will need.  If you plan on doing video editing, photo editing, etc, and i7 would be worth the investment.  Also hyperthreading =/= more cores.

I've checked some benches earlier and...

 

PassMark CPU Mark - October 2013

 

Mooshi's Core i5 2500 @ 4.5Ghz OC'd  8,226 / Intel Core i5 2500K (quadcore) 6,370 *stock* 3.3Ghz

 

AMD FX-8350 (8-core) *stock* 4.0Ghz 9,086 (Q4 2012)
Intel Core i5 2500K (quadcore) OC'd 4.5Ghz 8,226 - (Q1 2011)
AMD FX-8320 (8-core) *stock*  3.5Ghz 8,169  (Q4 2012)
AMD FX-6300 (6-Core) *stock* 3.5Ghz 6,369 (Q4 2012)

 

This old quadcore is still keeping up with the higher cores. :V

 

I still thrash AMD on the single threaded performance, but not bad for the multithreading all things considered with a non HT chip from 2011.

[MrSuperb]

AMD FX 8350 / 8320 isn't a 'real' 8-core either

AMD FX 8350 / 8320 draw significantly more power

 

Although future games might use more cores, not everything in games is parallelizable (aka multi-threadable), many of those 'side-calculations' are probably less complex and you won't see 100% usage on all you cores. Futhermore not only the count of processor cores but rather the total performance for all cores is.

Listen every one i dont want an AMD processor i want an z87 motherboard like the asus gryphon because of the armor kit OKKKKKKKOKKKKKK

[kkzee123]

I already answered this, read the last post on the first page.

Sorry i was ragging and thank u for the descriptive answer it was incredibly useful but just to clarify u dont think the I7 isn't better because games don't recognize the threads properly but we don't know yet for future games  

[Razarza]

Well get a Haswell i5 then.

That a cool board.  I like the thermal armor :I  anyway.... If this rig is a predominantly gaming rig, then get and i5.  If you plan on running other complex programs and whatnot, (like video editing) then you will benefit from an i7.  At this point in time you WILL NOT benefit from hyperthreading in videogames, which is the ONLY difference in the i5 and i7.  Also as someone stated earlier, hyperthreading can actually decrease  performance (although marginally) in some games.

No thanks, i saw actual benchmarks showing tangible performance boosts over an i5, it's sufficient.

[TheRisingMyth]

Read what @Glenwing posted. It better explains what I was trying to say.

 

The thing is, even if HT doesn't represent that much of a performance boost, it is still a thread, and can effectively being taken advantage of.

 

In the context of coding light code that gets heavily multi-threaded on the 8 Core CPU (which i'm sure two of will be easily outdone by a theoritical single-core Hyperthreaded Intel Haswell CPU) (of the porting is done properly on PC) this may result in actual percievable results.

You can't think of hyperthreading as increasing the performance.  Physically, there aren't any more transistors on an i7 than on an i5.  The max amount of calculations it is possible for it to do is no different between the two chips.

 

What hyperthreading does is not to increase performance, but to prevent performance decrease, by holding backup tasks for cores to do whenever a thread is stalled.  When the CPU is being used inefficiently, hyperthreading recycles the lost CPU time and uses it for something else in the meantime, to reclaim the efficiency, whereas on an i5 that unused CPU time would remain unused and simply go down the drain.

 

Of course, if the program is such that the CPU is already making efficient use of its resources, then there is nothing being lost for hyperthreading to recover.  The CPU is already operating at high capacity.

 

This is the case with games, the CPU cycles are already being used efficiently.  "Optimizing code for hyperthreading" would essentially consist of taking a step backwards in game programming and writing games to be less efficient, so that hyperthreading can recover that lost efficiency and bring performance back to where it should have been in the first place if it had been programmed efficiently... If that makes any sense.

[AvoK95]

i5 and i7 = almost identical performance. In some cases the i7 even performs slightly less. 

[ACatWithThumbs]

I would say go with the 8350 it just seems the better option for "Next Gen" games.

[FireFox]

Except the i7 has hyperthreading, and next gen games seem to support more cores.

 

But isn't a single Intel core equal to two AMD cores or something?

Basically HT is a queueing technology or something right?

[nokturrduk84]

i7 for sure! You can see that BF4 has better fps with i7 comparing to i5 and I believe i7 will be better for future games.

[WoodenMarker]

It's not simple. Intel tends to have more powerful cores though.

In short, yes. 

[TechFan@ic]

A single Intel core is as large an AMD Module (two cores), but an AMD Module is roughly 50% more powerful than an Intel core.

More in-depth info here for anyone interested : https://linustechtips.com/main/topic/48571-intel-amd-architectural-discussion-how-far-ahead-intel-really-is/

[Glenwing]

Each AMD module has two integer clusters and one floating point unit.  Games do like floating point so in that regard it's similar to a quad-core, however integer performance still counts, so it's an 8-core in that area.  Can't really call it a quad or an 8-core, it's both, for different types of operations.
