7700k? I don't understand how they can rename a processor and call it a new generation when it's simply a small boost in clock rate? 6750K would be a better name.
 

Intel stated that it's 10 nm process (Cannonlake) was delayed, and specifically introduced Kaby Lake as a stop gap and explicitly said it would be on 14 nm. This was announced months ago. There was never any reason to think that Kaby Lake would be 10 nm.
 


No rumors or anything, I think it's just hope that Intel will make a bigger move on performance. The disappointment comes from the feeling of Intel yet again treading water. It's difficult to be happy about a release that is more of the same.
 
I see no real reason to get any of these, unless maybe you are upgrading an existing perntium/i3 skylake build. Bios updates are probably not installed on boards currently in the retail channel, and there are no Z270 boards yet. This launch is a waste of time.
 


During the process of getting the die shrink ready as well as during production of their current chips Intel (or any other chip manufacturer) learns a few new things and sees a way to apply them to the existing node and architecture and improve the existing line at minimal cost to them while providing a better product for their customers.

I mean, intel could just not implement these refinements I suppose but if it doesn't cost them too much money and makes their product (especially mobile products) better it makes good business sense to go ahead and make those changes IMO.
 
thank you very much AMD for beaing such garbage for the past 6-7 years. you have given Intel ZERO reason to release better CPUs.

since sandy bridge in 2011 there has been minimal improvements in CPUs.
it's kind of funny that a 6 year old 2500k or 2600k can still run the latest games as long as you upgraded the GPU.
I hope that Ryzen delivers for once. Somehow i'm worried that it will flop like bulldozer.
At least AMD gave nvdia a run for the money with their last gen R9 fury. just look at the difference in each generation of GPUs. 900 series destroyed 700 series. 1000 (pascal) destroyed 900 maxwell. This is the type of advancements i'd like to see in the future.
every penny i spent on my GTX 1080 was money well spent for me.
But the 6700k i got last summer........even overclocked to 4.7 it's only about 20% faster than my 5 year old i5-2500k oc'ed to 5.0. 5 years in computer tech = you should be almost doubling the speed.

Come on AMD........you can do it......
 


I think it's more likely that Intel wants to keep themselves in the spotlight and OEM's are demanding some form of product refresh to advertise. Same as the OEM's did to GPU companies, hence the OEM only Radeon 8XXX and GTX 8XX series.
 
In other words, my 4770k is doing just fine. However, I would not mind getting this for DDR4 because I want a miniITX build with 32GB RAM (16GB X 2), which I can't do with DDR3 (I got 8GB X 4 now) on the Haswell platform. :/
 
I'm eagerly expectng the unlocked i3 review, and I hope it gets used in a SBM. Might find some interesting results, especially since it won't be very power limited, so might achieve ~5.2 if lucky enough.


EDIT: I'm actually excited enough about the whole idea that I will benchmark an artificial OCd haswell i3 (4770k 2 cores disabled). Might get interesting.
 
If my Sandy Bridge Asus P8P67 Pro motherboard hadn't bit the dust, I'd still be using my i5 2500K rig as my primary gaming rig instead of just biting it and upgrading to Haswell. It's interesting to note that productivity performance gains continue to make progress with each tick-tock but gaming performance not so much.

It used to be both would happen pretty much in parallel. Games today are more on the GPU with higher resolutions and more complex polygon graphics tech. So if you are more productivity oriented with applications over gaming, you will continue to reap noticeable benefits from an upgrade very second or third generation among chipsets.

And by "noticeable" I'm talking about heavy multi-threaded programs like video editing software. The difference between an Ivy Bridge i7 3770K and Skylake i7 6700K is significant when running Sony Vegas Studio: the Skylake is 10 seconds faster in a 200MB 1080p video file. That may not seem like much at face value in a short benchmark test, but when you have an hour of 4K video to render 40GB large, it's massive.
 


Good news for you is that Zen is looking good and we are approaching near retail samples. A low clocked SR7 was able to put itself in the i5 Skylake/Broadwell performance bracket, given that a i7 6900K was regarded as slower than the 6600 and 6700K in gaming per CPC given lower clocks if you add the 12% clock bump on final product, the SR7 probable matches the 6900K and 5960X in gaming and productivity. for the end user this is far from BD which was a marketing and performance nightmare. AMD hasn't done the hyping, it has been independent sources that have historically been down on AMD due to the BD arch.

While Zen may not be better than Intel on everything intrinsically, they are not a distant second, they have comparitive performance and the pricing is where it is going to be interesting. if they ship the SR7 Black edition at $500 and it is Broadwell/HWE performance, that will destroy intels pricing position. the SR3 4c/8t with mainstream i7 performance priced at sub $200 puts Intel in a very bad pricing position. If they don't drop prices AMD will steal huge market gains, if they drop the prices their FABs overproduces and undersells to value that cannot be made up overpricing. It is a major shake up and I am actually curious to how intel plays this one.
 
Yeah Jim, I totally agree. AT LONG LAST I upgraded from my good old E6750 to an i7-6700 on Black Friday. What was the final push that made me upgrade?

Was it Visual Studio 2015? No.
Was it SQL Server 2016? No.
Office? No.
Hex editors? No.
Smartphone firmware flashing tools? No.
Retro gaming? No.
VMs? No.

It was Chrome - a freaking browser. Over the course of eight years, NOTHING that I used required me to upgrade anything other than my graphics card and going from 2GB of RAM to 4GB in my old machine. Look, everything is now far, faaaaaar faster, but it was still usable.

As a side note, in eight years, in the same 65W max TDP and for the same $200 taking inflation into account, I went from 2C/2T @ 3GHz overclock to 4C/8T @ 4GHz. To me, that is amazing. It shouldn't be, but it is. I'm currently hunting for some useful software that I can use that will make full use of my CPU other than 7-zip. :-D <3
 
I am still using a i7-2600k@4.2 and it's still suiting me well. I was actually very interested in KL for the IGP. I use quick sync, frequently (though on a i5-3570k) and like the h.265 stuff in the new IGP, though not sure how the new performance of the HD630 is going to be. As for Ryzen sure it looks very interesting compared clock for clock to KL but if KL enjoys 500-1000mhz of headroom and Ryzen doesn't, then that will be a disappointment. Personally 8 cores vs 4 at nearly equal efficiency and similar cost, I think Ryzen will be a big winner. Though I think Ryzen is going to try to compete with Intel E series. I also doubt Cannonlake is going to be the big improvement Intel needs to keep their margins.
 
Please test handbrake quality with cpu vs. gpu/quicksync. I'd like to know if they FIXED the quality drop when using the gpu/quicksync vs. cpu only. I'd be more interested if handbrake can finally turn on the quicksync and not look like crap. I currently turn OFF my 4790k's gpu.
 
Every generation since Sandy Bridge (Core i 2000 series/2nd Gen) has left the door cracked for AMD...but they released Bulldozer at that point and wasted 5 more years on it. This door is wide open for [Ry]Zen since all of AMD's benchmarks pit it against Skylake, which has essentially the same performance as Kaby Lake.
 


If you have a bad architecture you can't just end it, Intel did the same with Netburst, had to ride out 3 years of rubbish before they came up with Conroe. AMD had to run through their BD evolution and try make what they could of it. You can say that Zen represents what Phenon and Phenom II should have been but were to conservative and had to much dying legacy on it. Zen is great timing for AMD, we are very close to the IPC brickwall and Zen just parks itself in a situation where intel just really can't do much to pull away again. BD was never going to keep up with Intels rapid die shrinks.

 
Again Ryzen and 7700K is waste of money in my opinion when you can get unlocked 14/28 Xeon and overclock to @4.0Ghz if you are lucky to snatch one from ebay, i got mine from a friend who works HP and they were tossing those ES models. Paid mine < $300. 14 Cores 28 Threads Xeon at 4.0Ghz is sick sick sick, along with 1080 SLI.

I know only two type of boards supporting Xeon engineering samples, retail or oem ones and that's Asrock x99 series (all boards) and MSI x99 series (all boards).

When you buy Xeon CPU, you will see C0, C1, C2, D0, M0 revision. You want to stay away from C1, C2 because usually something is broken with them. For example C1 SR0KX vt-d feature is broken, does not work. In some hyperthreading is not available, so you have to be careful. So shoot for C0 or M0. Now among all those C0 or M0, some of them are unlocked and in order to get one, someone has to check that for you...i was lucky friend of mine found one.

If nothing go for M0 revision (possibly retail) because they overclock well. For example 12 core 2.0Ghz will turbo to 3.0Ghz for single core or 2.7Ghz on all cores. Now in MSI and Asrock boards you can force all cores to run at 3.0 and with little FSB tweak you could get close to 3.2Ghz which in 1440p and 4k gaming is insanely good.
