What is the big difference between i5 and i7 intel cores?
>>51779731
hyperthreading
cache
clockspeed
Nothing.
>>51779731
about i2
i5 - i7
=> -2i
Overall ~25% better multi-core performance for nearly twice the price. Yeah...
Also i5s have no hyperthreading so they can't pretend to have 8 threads like i7s can.
i7s are a meme

Even if synthetic benchmarks were accurate, you could not use them as a ratio. A 25% higher score does not correspond to 25% higher performance. Synthetic benchmarks are pretty bad at simply ordering processors, but they're utterly worthless in trying to see how much faster one processor is.
>>51780046
I hate to agree with tripfag but i7s really only bring about 25% better OVERALL performance. i5s and i7s literally have the same single-core performance.
See better benchmark in pic related.
>>51779731
Hyperthreading
>>51780141
I thought i7s had slightly worse single core performance because of the hyperthreading?
>>51780046
Depends on task. It's safer to turn off the hyperthreading meme off though.
>>51780180
whoops meant to quote >>51780158
Basically you only need an i7 if you run virtual machines or whatever otherwise an i5 is just as good
Hyperthreading is pretty much just a gimmick on CPUs. Cache is important, and so are the virtualization features.
Most vidya gaems are programmed horribly and don't aptly use more cores or cache anyways, so just get an i5 if that's the most you'll be doing.
>>51780218
FX-8xxx series CPUs are better for VMs since they use "real" threads.
Take the frame rate of a game running on an i3. For example let's say, this game runs at 30fps.
Divide the i3 into thirds, so each i is 10fps.
i2 would therefore be 20fps.
To answer your question, in this case the difference between an i5 and an i7 for this particular game would be 20fps.
Obviously the fps would fluctuate from game to game but the basic ballpark percentage will be the same in everything.
>>51780250
They're cheaper too.
>>51780309
well memed friend
>>51780250
CMT is really not much better than SMT.
>>51780360
True but AMD is still the better choice because of the lower price, at least for VMs.
i7-4770K: ~ $320
FX-8350: ~ $160
The performance difference between these two processors is like 10% too which can be equalized by OC the FX ~400 Mhz with a $40 aftermarket cooler. You still save over $100 with AMD.
>>51780512
whats a compatible cpu for laptops to run VMs
i5s are for casualfags and their gayming/facebook machines
>>51780559
i7s I'm afraid. AMD offers no good CPUs to run VMs on a laptop.
If you want to run VMs stick to a desktop with AMD else things will get super fuckton expensive with jewtel based laptops.
>>51780586
i7s are for goys

Well shit i ordered the wrong one and paid more for nothing lol oh well.
>>51780665
Don't speak so soon. If you play games, future games are only going to use more and more cores. You'll see more benefits in a couple of years anon.
>>51780647
All you really need to run VMs are at least a dual core cpu, and at least 4gb of RAM. I've had to use VMware Workstation for 17 weeks straight on an HP Notebook 2000 and a 2tb ext HDD.
>le ebin i7
>>51780688
The 4790k still has only four cores. Hyperthreading doesn't work with homogeneous workloads, which are common in games.
>>51780692
And the processor in that HP Notebook 2000 is a shitty AMD E-300 APU.
>>51779764
iApprove
>>51779978
If you don't do any power work on a PC, that is
>>51780141
Anyone buying an i7 should know this
>tfw Premiere Pro, LR, and most new games slam the processor to 100% on all 12 "cores"
>>51780712
That must have been excruciatingly painful.

I remember I have a Hyperthreading Pentium 4 and cant play Witcher 1
Hyperthreading is a meme
>>51780793
>Pentium 4
>>51780728
i7s are still a meme because if you need to do CPU intensive tasks like video encoding and ray tracing, xeons are better.
For example just one E5-1620 costs ~$300 (even less on ebay). They also have around the same performance as i7s too. Put 4 of those xeons on a quad cpu motherboard and you now have a fuckton of raw cpu power.
>>51780814
You better get that neck checked out rick.

>>51780734
Nope. It was usable.

Jesus christ anon, get it together.
>>51779731
an i5 is an i7 that had defects in the cache and intel turned hyperthreading off
>>51780910
Not true, else i7s would have the same multi-core performance as i5s.
>>51780829
Xeons have:
- slower cache
- unofficial support on non-server motherboards
- lower clock speeds
- no OC
Skylake Xeons won't even post in a non-server board with the right chipset now and that's how all Xeons will be from now on out.
>>51780909
I'm sorry anon
>>51779790
kek
>>51780647
This isnt true. Look at their new "pro" line of APUs

>>51780945
>Xeons have:
> - slower cache
Nobody gives a shit, x264.exe certainly doesn't
> - unofficial support on non-server motherboards
Well duh, they're server CPUs.
> - lower clock speeds
This only matters in vydia gaems.
> - no OC
Again, only matters in vydia gaems.
>Skylake Xeons won't even post in a non-server board with the right chipset now and that's how all Xeons will be from now on out.
uhg...
>>51781081
>clock speed only matters in games
idiot detected, enjoy your server hardware for facebook.
>>51781100
He was talking about video encoding and ray tracing you niger. Do you have any idea what four e5-1620s (32 threads) are capable of doing?
Of course Xeons are shit for everyday use which is why only encoders/3d artists would use them
>>51781162
Name 1 AAA game that will max out even 4 cores. 32 cores is worthless.
>>51781236
I want 1000 cores
>>51781236
I know what you are now, you can't phase me now.
but the i7 performs better in the newest games
>>51779731
Nothing. Especially since you can OC an i5 to the same speed as an i7.
Can someone send the children talking about their toys back to >>/v/ please? The adults are trying to talk here.
>>51779731
Intel's level of jewing your money for little to no difference if you don't need hyperthreading
>>51781282
The difference is like 5% better frame rates. Not worth giving jewtel more shekels.
>>51781299

>>51780664
Correct.
Xeon is where it's at.
>>51780309
And for almost half a minute I tried to figure out what you say
I should to go bed
>>51780180
How can I turn off HT from my i7?=
>>51781162
>Of course Xeons are shit for everyday use
The hell they are.
Xeons make excellent daily drivers. What common task are you going to be doing a Xeon can't handle?
>>51781455
muh vydia gaems
>>51779731
You buy one if you're a dumb poor fag, and the other if you're not.
>>51781537
They can play games just fine.
>>51781236
Metal Gear Solid V: Ground Zeroes uses around 12 cores on my system (13 showing in afterburner but I assume one is my OS).
They're not maxed out, but they don't really have to be.
>>51781650
GZ was so fucking good, the level design and the difficulty of it all + the wa yyou could play it in 20 different ways.
Fucking TPP sucked ass
Dark Souls using 8 cores. Most of it is focused on one, but it puts little tasks here and there on separate threads.
>>51780734
For you
>>51781650
>all those 0% loads
you need 24 core mang
>>51781885
I do need 24 cores, gaming isn't the only thing I do.
>>51781889
If you ever get the time I would love to see the result of this with dolphin emulator's multithread option. I max out my 2500k with it on f-zero.
>>51782186
Poor results. Dolphin requires a high clock speed on a single core for best performance.
I've tried F-zero GX and I could not sustain 60 fps. Twilight Princess is playable due to being locked to 30fps.
If one is buying a computer solely for gaming I recommend a CPU which can reach 4ghz, since this unlocks Dolphin and adds literally hundreds of very high quality games to your options.
But I didn't buy my computer solely for gaming, so I'll have to live with Dark Souls II instead of Skyward Sword.
>>51781816
What's the max FPS you can get with that?
>>51781650
>>51781816
at least make it fucking white or something. jesus
>>51780158
Only if you're running an OS that's bad at scheduling.
>>51781055
What about them? They're exactly the same as the consumer range just with Pro written on them, they're no different in hardware.
>>51782379
Depends on the game and settings. Dark Souls will only go up to 60fps with DSfix, and I easily hit that mark.
If I dial back settings I can go over 100 fps on many games, but that's not particularly impressive. For actual PC games (not emulated) the CPU isn't often going to be the bottleneck.
A few disabled cores here and there is the only difference between i5 and i7.
Functionally, they should be about identical. There's also the obvious conclusion that the i7s, being higher binned chips, would overclock better.
>>51782387
Pink is the default color on afterburner, ya noob
>>51782349
> If one is buying a computer solely for gaming I recommend a CPU which can reach 4ghz
implying 4ghz on bulldozer is the same performance as 4ghz on haswell or above
> what is IPC??
>>51782658
4ghz is just the starting point in the choice. I'm sure someone has overclocked a Pentium 4 up to 4ghz and that probably wouldn't do well either.
>>51782580
Thanks. I was mostly interested in what you could get in Dark Souls.
Didn't know DSFix limited you to 60. I was hoping for 120 when I eventually build my PC, but I know it's a pipe dream for most games.
GRID 2 using 14 cores completely maxed out on all settings. This is an "old" game.
Games from good developers usually do what they can to take advantage of higher core counts. You don't get complete utilization, but every little bit helps.
>They didn't get a 4790k last year for $280
>>51783594
What would you do with it cheaper CPU couldn't do?
>>51783641
Everything, seeing as how I didn't buy a cheaper CPU.
>>51783696
You don't need a powerful CPU for gaming.
Xeons are better for real work.
I'm afraid you may have fallen for a meme, anon.
>>51781162
Are opterons any good for that too? Or are they shit compared to xeons for everything?
>>51783741
Opterons can be fine too, depending on the model. But many of them you find will be very low clock speeds.
>>51783720
>falling for the server processor meme
People are just buying Xeons to be edgy.
>I reject your onboard graphics and substitute my L3 cache
The ones that actually match or outperform i7s are more expensive.
>>51779731
Best one is i9
>>51779790
