Intel Core i5-7600K Tested, Negligible IPC Gains

[Dammeron]

Wow. Just wow.

Especially that it wasn't short at all. Athlon XP, 64, 64 x2, FX... All these were much better than their Intel counterparts. Intel came up front with Conroe and that's when current situation began.

Clock-for-clock, the i5-7600K is just about 1% faster, indicating that the "Kaby Lake" architecture offers only negligible IPC (instructions per clock) performance gains over the "Skylake" architecture.

I need to correct you there, Kaby Lake and Skylake have identical IPC.
If a benchmark shows a 1% edge to Kaby Lake, it's because of more aggressive boost.

I expected at most 5% increase (IPC wise), not 1%. I wonder how good the iGPU is. If it continues 20% increase each gen, Kaby lake's iGPU would be pretty decent by now.

We have not seen a real IPC increase of 5% since Sandy Bridge. Intel always claim to have ~10% increase every iteration, but in reality that is inflated because of dedicated hardware features and similar.

I mean I was playing Civ 5 with iGPU on i5-6200U.

I guess Intel doesn't see Zen as a threat or they are bringing improvements for Cannonlake.

Cannonlake will only bring a node shrink and fixes, but no architectural overhaul. That will come in Ice Lake (~2018).

Av nae fuckin clue wit the fuk youse are on about but am gonna tell ye its baws man, fuckin baws.

That (the NSFW bit) sounds like a normal work day in a Dublin office too.

(with a different accent though).

Although abysmal IPC improvements were expected, am I the only one that thinks that producing the same heat at 4.2 GHz as Skylake at 3.9 GHz is pretty good achievement on the same 14nm node?

Intel's power efficiency is nothing to scoff at because they've spent billions of R&B resources into it. We are seeing the fruit of their labor in 65w TDP i7 non-K.

Nvidia also seems to have taken that note from Intel because their GPU power efficiency is amazing also.

I don't think many here care about that though.

I do. Especially if that part that performs better than another and consumes less power at the same time.

I have to agree with all the comments that consider kaby lake not much of an upgrade over Sandy bridge. If you have a Sandu bridge or newer cpu, upgrading will be a pretty bad price/performance ratio. You aren't missing much tech either if you have a desktop since you can add most missing tech via PCI-e.

For laptop users tho, the native h.265/AVX igpu rendering and power efficiency is a pretty good game changer.

Also, I lol at all the comments about Intel being 3 steps ahead on AMD. During the Athlon64 and Athlon X2 days, Intel were pretty far behind. Oh and when AMD acquired ATI and introduced the first iGPU, that was also a pretty big win.
The bottom line is that when you say "never", you are never right....

I disagree.. so does Anandtech. The difference between Sandybridge and Skylake is on the order of 25%+ IPC (was 25% to 4790K.. 6700K has a bit more on top of that). Its well worth it to upgrade from SB to Skylake or Kaby Lake.

Except not. tick tock is gone. Intel is doing away with that now.

Correct, they are doing away with that. KL is still what Devil's Canyon was to Haswell, nada for IPC. You don't have to call it a tick or a tock, but the results do speak for themselves.

 

[birdie]

It surely looks like everyone has gone collectively dumb. Totally dumb.

Kaby Lake features absolutely the same CPU core as Sky Lake. There has to be zero IPC gains.

The only performance gain in Kaby Lake is from higher frequencies (100-300MHz) and speed increases in switching from low power modes to high performance modes.

Someone, right above you, said KL is still what DC was to Haswell... nada for IPC.

Intel hasn't claimed any increase in IPC though. Theyre new model is process, architecture, optimization. The new process was launched with broadwell (14nm), then Skylake launched as a new architecture, on the same 14nm node, and now Kaby Lake is just optimization of that process.

And there are those who must have the latest no matter how silly it is.

Look how many Apple brainless sheeps are out there. They change their phone each year like mindless drones, even if, for example, the difference between 3 years generations of iPhone 6 , 6s and 7 is mediocre to say the least...
Exactly the same is with the intel CPUs situation right now.

 

[Recon-UK]

Giggity.

 

[geon2k2]

Question is, do old i5,i7 owners have a reason to upgrade?
How is intel making the money, only from new devices and very few upgrades?

 

[newtekie1]

You do know that AMD had the first 64bit CPU?....

Yeah, no they weren't, not by a long shot.

Nowadays many consumers upgrade their Machine's CPU ( in this case Intel consumers ) not because they really need to but just for the sake of
spend money.

No. This is not true in the least. Hardcore enthusiasts amd prosumers with money to burn might, but they are a tiny, insignificant portion of the market.

 

[P4-630]

Yeah, no they weren't, not by a long shot.

They were before Intel I meant.

 

[FireFox]

Hardcore enthusiasts amd prosumers with money to burn might,

I am not a hardcore enthusiast and i used to upgrade CPU often, my last i7 machine was a (3770K) after that i went Xeon because all the newest i7 are almost the same.

Hey, hey ... wrong count is wrong ... there are more of us ... people forget how efficiency of an architecture and process quality affects everything from thermals to achievable clocks, and most importantly enables "fattest" HEDT chips to be under 140W

 

[newtekie1]

No they weren't.

 

[TheinsanegamerN]

No they weren't.

You are technically correct, as MIPS had a 64 bit CPU in 1991. alpha (1992) and SPARC (1995)and IBM (1995) all beat intel (2001) and AMD (2003) to the punch. However, the AMD implementation in 2003 is the one that dominates windows servers today, and a large number of servers outside of specialized servers run AMD64. The 2001 intel implementation, itanium, never caught on and was a disaster in sales and time wasted.


However, in the DESKTOP space, where 99% of consumers exist, AMD beat intel to the punch by three years. athlon64 came out in 2003, core 2 came out in 2006.
