I5 3570k vs i7 3770k vs wait for haswell

[destwong]

CPU=??
GPU=2x gtx670
MOBO= mis Mpower


so which cpu should i take ???
gaming & minor multitasking together.

If you're gaming, 3570. I would get the K model however, last longer cause you can overclock it.

 

[stantheman123]

Whats your current rig. also i was in the same spot. just for you to know lga 1155 is dead. and i didnt have a pc for gaming. so i bought a amd 6300 since its on the am3+ socket where steamroller will be on. Risky decision on my part since what if steamroller isnt even fastesr than ivy bridge haha. anyway if you Can wait def get haswell. if not just ride that 3570k. i wouldnt recmoned what im doing since its a risk idk how good steamroller will be and ur getting sli so either 3570k or if you can wait haswell

phenom 2 1055t with gtx 670

Why 3570 guys? I mean 3770 is better and can act quite better isn't it?

 

[stantheman123]

You have a phenom? Definltly hold out till haswell. Overclock it a bit if you can. like i said lga 1155 is dead. and true blood in gaming theres 0% diffrence the only diffrence between i7 and i5 is hyper threading which helps in applications that acctually uses it which games dont

 

[Guest]

I got it mate

 

[azed3000]

Id personally wait for haswell, but if you really want a computer now just get the ivy bridge, it's only going to perform 10% lower to the haswell, which is barley noticeable. Also keep in mind we are yet to know its overclock-ability, if you noticed the ivy bridge cant oc as high as the sandy bridge, even though it outperforms sandy bridge core per core, once sandy bridge hits a high enough clock, it out does the ivy, so yea there's both pros and cons to waiting. In the end upto you.

i planing to sli but my mobo do not support it
this is my main reason to change cpu

 

[stantheman123]

Well unless your on 1440p or 1600p or higher i wouldnt really say SLI/crossfire is needed. If you really wanna sli then jump on a i5 3570k and maybie a asrock extreme 4 z77. if you want

i going for a 3d gaming so sli will help a lot haha
previously i looking at msi z77 Mpower but asrock mobo really cheap price point catches my eye. Is it realizable? (going to keep it for at less 2 years with with 2 years interval GPU upgrade)

i know is off topic but what sound card should i go for? mid range or high end? (around $100 or at $200 range?)
will i notice any difference in sound quality ??

The i7-3770 has Hyper Threading (HT) and it does not have an unlocked multiplier for overclocking.

Games do not make use of HT, over the past several years benchmarks have shown that on average HT decreases game performance by about 1% - 2%. Unless you use programs that can make use if HT, then you are not really getting any benefit from HT.

oh sorry i forget to put a K there
i 100 % going fo a K model just not sure which one to go with

 

[jaguarskx]

Since you are only doing "gaming & minor multitasking together" there is no real need for Hyper Threading... unless you plan on doing video encoding and using a video codec that supports HT.

 

[jaguarskx]

Personally, I am waiting for either Haswell or Broadwell (2014).

r u sure about it?
there is bench showing that i3 with HT show improvement due the game run on 4 core.
I will not be upgrading it for some time (2 years minimum but will upgrade gpu)

Provide a link to the benchmark. It might be specific to the game you are referring to because over the years there have been dozens of CPU benchmark reviews that have shown HT not providing any benefits for games.

Dirt 2

i5-661 (HT on) ………….. 96.47
Q9550 (2.83) …………….. 94.51
i3-540 (3.06)…………….. 90.43
E8600 (3.3) …………..… 73.40
i5-661 (HT off) …………. 72.02
E7400 (2.8) ……………. 56.47

This review test has benches for the i5-661 with/without HT (hyperthreading). If you check that sites processor reviews, the original i3-530/540 review also has benches with HT on/off. In well threaded games like Dirt 2, one can get somewhat of an idea that HT is helping considerably by comparing against the pervious generation dual cores. The dual core i3's are generally substantially faster than the previous generation of dual cores in multithreaded games and multithreaded gaming is one of the areas (along with video encoding) where HT makes some of the biggest performance gains. An i3-540 is almost as fast as a Q9550 in Dirt 2, and substantially faster than a higher clocked E8600. It isn't going to take much of an overclock for the i3-540 to outrun the Q9550, and the i3 mops the floor with the slower dual cores under the E8600.

In this computerbase i3-2100 test, HT boosted performance 71% in the game F1 versus no HT. Surprisingly, in the same game F1, the i7-2600K loses 4% performance by enabling HT … computerbase i7-2600K. There are other games where the i7-2600 drops in performance (-5%) with HT on in that same computerbase review, like RE5, where the i3-2100 sees a 46% gain with HT on.

In BF:BC2, HT boosts performance on the i3-530 by ~ 50-60% … overclockers … scroll down about halfway in that thread for benches of the i3-530 with/without HT. HT makes a huge difference in this game. The i3-530 looks to be averaging below 40 (with several dips in the low 20's) without HT, and close to 60 with HT on with only 1 dip slightly below 40. It's the difference between unplayable and half decent frame rates for BC2.

You can also get a pretty good idea how much HT is helping in games where there is a G6950 in the review (2.8Ghz dual core Clarkdale with no HT and 3MB L3 vs 4MB for i3-530). The dual core Sandy Bridge processors like the Pentium G850 (2.9) G860 (3.0) could also be compared to the i3-2100 (3.1) if a particular review has those processors too. In this Techreport BF:BC2 test, the i3-560 (3.3Ghz) is 81% faster than the Clarkdale dual core without HT G6950 (2.8Ghz) with an only 18% clockrate advantage. The i3-560 also easily outran the Q9400 (2.66Ghz) in that BC2 benchmark.

Okay, that seems interesting... Dirt 2 definitely does get a boost from HT it seems... However, that is for a resolution of 800x600. Below is a direct link to the chart.

http://www.computerbase.de/artikel/prozessoren/2010/test-intel-core-i3-530-540-und-core-i5-661/27/

Now compare the same game in the same review article, but at 1680x1050 resolution...

http://www.computerbase.de/artikel/prozessoren/2010/test-intel-core-i3-530-540-und-core-i5-661/33/

The performance difference has basically been wiped out. So... yes you can say that Dirt 2 benefits from HT, but only at the lowest resolution. If you plan on playing Dirt 2 at the lowest resolution, then by all means buy a Core i7-3770k.

You should also check out benchmarks for the other games, you are not going to notice much difference with and without HT.

Overall imho 2 core and hyper threading makes a big difference for gaming.

Based on the benchmarks in that German review referred to by the OP and the link to the review I posted, your opinion would be incorrect.

The benchmarks shows that Hyper Threading has very marginal benefits for games. I think the benchmarks mostly showed around 2 FPS increase in performance. The exception seems to be Dirt 2 @ 800x600 which shows a dramatic increase in performance; I think it was around 25 FPS to 30 FPS. Regardless, it was substantial. However, the benchmarks for Dirt 2 @ 1680x1050 showed only around a 2 FPS increase.

You are entitled to your own opinion, but the results of all the benchmarks in total from that German review clearly shows Hyper Threading does not really improve performance by much.

Hyperthreading in some games Gets less fps and some games more. no reason to pay a 100. and yes asrock is very reliable but if your not comfartable could always go asus or msi.

 

[azed3000]

Hyperthreading (8threads) will be utilized much more in the near future, battlefield 3 is the only game out at the moment that utilizes it properly. So dont cross i7s off your list yet. The reason the i5 661 with hyperthreading does so well is because its 2 cores 4 threads. Games at the moment utilize all 4 threads, surpasing dual core. Thats why i5 with 4 cores no hyper threading does so well, cause there are 4 threads. Hence why the dual core i5 with hyper threading on also does well, cause once again its 4 threads.

The same principal applys to i7, once games start utilizing 8 threads as oppose to 4, it will make a great deal of difference.

So basically to sum up, the performance of games is dependent on thread count, not core count. So whether a cpu has hyperthreading or not is out of the question. Once games start utlizing 6-8 threads, 4 core i7s with hyperthreading will be the new gaming cpu.

And that wont be for atleast 2-3years so. get the i5 3570k.

If you have a phenom why change platforms unless you are running a old AM3 socket.

My honest opinion if you are hell bent on changing then wait for Haswell with a new socket rather than buying into EOL technology.

im good with any thing haha
not a in any team (amd, intel, nvidia, mis etc) just need performance vs price.
