Intel Core i5-3570K vs. i7-3770K Ivy Bridge

[FireKillerGR]

Intel's latest Ivy Bridge processors promise extra high performance in every sector (gaming, encoding, etc.). Today, we will compare the performance of the most popular models: the Core i5-3570K and the Core i7-3770K, at stock and overclocked.

Thanks for the review. Ignore the upcoming complains.

Thanks for the review. Ignore the upcoming complains.

Thank you but I do not ignore anything
It is my first review which means that its normal to have things to improve and include on it.
So, possible complains will be used as a guide for future reviews.

 

[Disparia]

Yeah, guessed as much. Got the wife a 3570K last month and saved $100 as there would be no difference based on her usage.

I'll take a 3770/K/S/T though, for good gaming performance while archiving or transcoding.

Great review!, Preety much if you want to game get the 3570K and if you need multi threads for work get the 3770K.

The only HUGE problem with these CPU's is that they have such horrible cooling. how can a cpu hit 80c+ on stock! With such a small nm and TDP of 77 that's just sad my Q6600 with 65nm 105w TDP stock it hit's Idle 34c Load 49c and Oc to 3Ghz 58C.

I'm happy to see a TPU CPU review I wish TPU could get some more.

For our tests we overclocked by adjusting the multiplier on both processors. The maximum we achieved with the i5 3570K was 4.5 GHz at 1.335 V and 4.9 GHz for the i7-3770K at 1.32 V.

As you can see, it is crystal clear that we were not that lucky with our 3570K in comparison to the 3770K, which overclocks better.

Instantly imagined that when saw a Malay batch for the 3570K and a Costa Rica batch for the 3770K.

Great review/comparison, FireKiller! Hope we see more around here!

 

[erixx]

Didn't know you, great review man! And I feel better after the scaring title!

 

[AlienIsGOD]

this makes me want to get an aftermarket HSF even more when i get my i5 3570K, as stock cooling @ 4ghz is pathetic at 80 C

Yeap exactly; its all about TIM.

More reviews in the future

Do not believe in batches my friend, have tested more than 7 Ivy Bridge processors the last 6 months. Batch just give an average result nothing more
My good i7-3770K is Malay and it can go higher than me previous Costa-Rica

Anyway, thanks for your message, really appreciated

If i was to get real picky about the review it would be the following
*http://www.techpowerup.com/reviews/Intel/Core_i5_3570K_and_i7_3770K_Comparison/3.html Needs a pic of the 3570K OC also and in the Test System you didn't put the GPU used.
*I would like to see a few more games that possible are more CPU dependent.
*On the temp page would be nice if you could add a accurate reading of the power that the cpu draws.

I still really like this review! and hope to see more.

Exactly. Looked for the GPU after seeing those 50FPS marks in Metro 2033 but it wasn't on the test setup...

You're actually the first person i see here on TPU that has a Malay 3770K that OC's better than a Costa Rica one...

Well, i do not review processors so... lesson learned!

Just added the Gpu on the Test Setup
Thank you

Sorry but I'm not entirely sure what the point of this review even is.... It appears to be a clock-for-clock comparison which of course the processor with a larger L3 cache and hyperthreading is going to win (given the same architecture). What would have made it interesting to me would be to also turn off the hyperthreading of the i7 and add those results to the mix as well. At least that way you can see the benefit of of going from the i5 @ 4.5GHz to the i7 (no HT @ 4.5GHz) but with its larger L3. Then from there we can also see the percentage diff when you turn on HT. Otherwise, more expensive processor is faster.

Edit: Don't get me wrong, nice review and all and I'd like to see more processor reviews on TPU; however, these results I can get just about anywhere.

 

[qubit]

I don't like getting second best, even if the difference is fairly small, so I'd go for the 3770K.

So, Ivy Bridge CPUs are great (thermal performance aside)? Yes, of course, that's obvious!

Nice idea Beertintedgoggles
Will do that on the next reviews don't worry

 

[chinmi]

So for gaming, i only need the 3570k right... ??? great review as always by tpu team
this will save me around $100,- and gonna put that money on a better videocard upgrade

 

[Ikaruga]

Thanks for the review.

I would like to point out that - in the gaming section - you compared the performance of the CPUs with GPU-limited gaming scenarios (for example Metro2033 is flat out entirely GPU-bond). While a single 680 is an awesome card indeed, it still struggles with 1080p when you max out everything to ultra in games.
I recommend next time you try games which are more CPU-bond (Civilization V for example).

any other games that you can recommend for cpu testing?

 

[Deleted member 67555]

What cpu hsf/cooler did you use in this review? seems I overlooked that info.

Good review btw.

this makes me want to get an aftermarket HSF even more when i get my i5 3570K, as stock cooling @ 4ghz is pathetic at 80 C

I use a $20 Xigmatek Gaia and my max temps so far have been 50c

 

[FireKillerGR]

Every cpu is different; and due to the TIM issue the difference is even higher.
I used Prolimatech Megahalems with a Sunon 120mmx38mm

 

[TheGrapist]

my i5 3570k is at 4.5ghz @1.288V,hit's 80C after an hour of prime 95 with an old h50 w/a san ace h1011.I haven't tried to push it further yet,anyways great review!

 

[Mals]

Good review

I do want to point out tho that I have used both of these processors and the in-game benchmarks make a very misguided opinion of their gaming performances.

I switched from the i5 to the i7 after some extensive in-game testing of games like BF3 on multiplayer maps.

In standard benchmarks, they see no difference, but games like BF3 utilize those hyper-threaded cores in a huge way.

My minimum FPS over a period of time in BF3 rose by over 25 Frames.

I game at 120FPS on a 120hz monitor. With the i5-3570k and GTX 670's in SLI I saw significant, frequent dips to below 80 frames.

Now, with the exact same setup and only changing to an i7-3770k I NEVER see my FPS go below 100. Lowest I've seen is 102 or so.

Just an FYI, it really makes a huge difference in online, multiplayer games. MMO's, FPS's, etc.

That's quite a significant difference you're seeing there and it tallies with other reviews I've seen.

It was a similar picture between the 2500K and the 2600K (AnandTech and Tom's Hardware, among others) so getting my 2700K was a no-brainer. It didn't let me down either and paired with my new GTX 590, my rig really flies in games!

I'm not Ikaruga, but... Skyrim!

Well which processor to buy. Both processors belong to the category of best buy then you asck for what you need and how much you are willing to pay for better. If you are a gamer could see that there is almost no difference in FPS regardless of the game. Serious advantage against i5k i7k model in which threads option 8 against 4 ensures fewer jams somehow brings pentium processor main advantage over AMD. Of course we all know how bad the thermal paste and so I suggest removing the cover and replacing as I also did in my CPU.Naw got much cooler processor and consequently easily it can be more wound. I use thermal EK CPU block Suprime LTX, D5 pump, EK dual top 2 LOOPS onle 1 for CPU, EK reservoir, EK Collstream RAD XTC (280mm x 55mm), 2 X 140/1300 fan Lamptron - Fen controller..Switch 810 Casy. Below maunt. temperature when as much as 5 Gh constant load at 1.35V very acceptable 30 ° C in a room with 23 C and under load 70 C max.
