3770K vs 3770S

**geno888** · 10-05-2012

Other than overclock capability, there are really performance differences between these two processors at stock frequencies?

If I'm not wrong, the S version is lesser power consuming (65W vs 77W).

Both processors have the 4000 HD graphic so they should have the same performance with quick sync.

Is the K version really worth the higher price? At 65W it should also be easier to cool the CPU.

@Dee: Can you say me approximately how much more performance do you get overclocking the 3770K compared to the stock values? 10% faster maybe?

**Dee** · 10-05-2012

The 3770K is clocked at 3.5GHz with turbo 2 up to 3.9GHz (stock)
The 3770S is clocked at 3.1GHz with turbo 2 up to 3.9GHz (stock) which probably accounts for its lower TDP of 65W

HD4000 is the same on both CPU's but you can also overclock the GPU on 3770K

I haven't run many benchmarks yet, but here is Cinebench with the 3770K at stock (5th entry)
The 3rd entry is the 3770K clocked to 4.4GHz.

The 3770K doesn't get hot at stock speeds, and even the Intel cooler supplied will keep it reasonably cool, but a third party cooler will do better, and be quieter.
I think you have an Arctic Freezer 13?
If so, that would do nicely at stock speeds on the 3770S, and would probably allow an overclock on the 3770K up to about 4.2 GHz.

Thanks a lot Dee

I didn't know that the graphic card could be overclocked too

Yep, on the K CPU the HD4000 can also be overclocked. I have mine at 1.5GHz at the moment, the stock frequency is around 1.1GHz.

**geno888** · 10-05-2012

Can you run quick sync tests to compare stock and overclock?

I will.

But it will take some time, as I have a growing todo list.

**geno888** · 10-05-2012

I'm looking forward

I don't think the S version is worth getting if you want to save power. Money would be better spent on an efficient PSU.

Actually power saving was not the reason why I asked

At the moment it seems that the S version is the only one easily found in local stores, and it also has a slightly lower price (that is welcome by my wallet

)

BTW, I think that when (and IF) I'll be able to afford a new machine, the K version will be widely available in local stores too

Ya'know Ivory Bridge isn't much of a step above Sandy bridge. If there are good deals on SB with a good Z77 MB in your area you might want to consider it.

**geno888** · 11-05-2012

I'm looking forward for Dee's tests to get a real idea of performance

Here is just a quick test.

Using an 8GB video, converted to MPEG4 1080P

I'm comparing Sandy Bridge to Ivy Bridge.

SB is a 2600K clocked to 4.4GHz
Ivy is a 3770K clocked to 4.4GHz

I used Cyberlinks Media Espresso for the conversion, as it supports Intel Quick Sync
SB = Quick Sync 1
IB = Quick Sync 2

Pic 1 is Sandy Bridge
Pic 2 is Ivy Bridge

**geno888** · 12-05-2012

Amazing!!!

Thanks a lot Dee

**Dee** · 12-05-2012

As a comparison
Here is another result, this time only using the CPU cores, with Quick Sync switched off

It states it still has about 1 hour 32 minutes to go. To long for me to wait.

**geno888** · 12-05-2012

Definitely amazing!!!!

I want that CPU

Why bother encoding prepackaged optical video media at all when you can download it?
Unless the video is Hi-DEF home videos or something personal like this-- mega processors don't really have a killer desktop app these days. Can you think of many other uses for 4ghz o/c 6-12 core processors?

Not everyone has a fast Internet connection. I can rip and encode a BD movie faster than I could download one. Plus I may want to watch a movie more than once, and I'd prefer to do that without having to pay for a second download.

I can think of many applications that can take advantage of a fast multicore CPU.

Video encoding
3D modelling and rendering
Photoshop, and other complex graphic manipulation.
Folding

In any case.
Folks should first choose the application they want to use, then buy the hardware to suit.

These things are not available in my zone, and if someday will become available I'm afraid to think about prices... Italy is a nightmare for these things

Moreover, internet connections are so unstable here that watching a movie in streaming is almost impossible

Me not for sure

At the moment the speed of my connection is pretty the same of an old 56k analog modem

I hope that on Monday someone will fix it

Thank you to Dee for the analysis and opinons! Very helpful.

sappu · 22-06-2012

Thank you Dee for analysis. It help me to determine the hardware.

NickCarriere · 28-06-2012

I am in the middle of all 3. I do not know which to choose, I do not want to overclock right now but knowing that the p8z77-v deluxe kinda wants you to OC I have been thinking about it. I also want this computer to last so I am spending 2.8thousand if i factor in the 3770k. I want to save money but i want this to last longer in the long run.

Generating (compressing) those downloadable HiDef files comes to mind. I just bought an i3 3225 (puny processor, huge QuickSync engine) because I get a lot of video from screen capturing. The cap program I use uses QuickSync to convert the ~20GB per hour captures to AVC at a more reasonable 6GB per hour.

The K processors have HyperThreading and unlocked multipliers to allow for easier overclocking. The S (as pointed out) is a lower TDP version without unlocked multis. S would be ideally used in mATX boards where one might want the power a quad-core i7 but whereby his board may limit him/her to certain TDP ranges (say a board that only supports CPUs up to 65W).

As for Cinebench, I believe is a poor choice of comparing two systems or even two CPUs. It's not a straight linear score composite (as I understand it), so a higher "score" doesn't directly mean that CPU A is better than CPU B. Use of real world apps to bench and examining the workload the CPU in question goes through typically would be a better way to compare.

Edit: checked Intel Ark, S apparently does have HT unlike energy-efficient variants of the past.

Thanks Dee. You helped me figure out what to buy
