Broadwell-K i7 5775C/i5 5675C

First engineering samples are starting to leak out!

Pretty useless until we know the cooling and voltage used, also bear in mind the 5775C has only 6MB of cache.

I7 5775C clocked to 5.0Ghz... Remember when Boomstick (Moi) said all hope was not lost ;)

All hope is still lost, since this wasn't stable even with 1.419V (suicide run) on air. All he was able to do was take a screenshot before it crashed.

Seems very similar to the 4790k overclocking, at least overclocking hasn't deteriorated even further from the 22nm node.

All that's left to see is how the 128MB of eDRAM will affect things, though remember these only have 6MB of L3 cache, so I suspect it will balance out the performance.

I'm much more interested in Skylake at this point, since we get the vastly improved Z170 chipset, with much greater PCI-E lanes for SSD's.

Disagree, these chips look like an alternative to 4770K / 4790K without having to switch mobo or buy DDR4 like you do with Skylake.

If they can reach 4.8Ghz > 5.0Ghz on air they def have potential, especially if they run cooler.

Obviously if your buying a new setup Skylake makes more sense but for people already on Z97, good to know these chips aren't turkeys.

Skylake really isn't all that either, still only 4 cores / 8 threads. X99 is a much better option for most people. For small form factor Broadwell / Skylake make sense.

Personally I'm skipping all this until we see AMD's Zen and Skylake -E / Cannon lake next year.

I never believe OCing results until real-world reports can be collated from dozens of forumites.

Very true, I'm pretty sure there was some pics of ES 4770K's doing 5Ghz on air back in the day. Yeah that turned out not so well lol.

All I'm saying is these i7 5775C's don't at least look like turkeys. They might have a place for Z97 owners.

Tbh neither Broadwell or Skylake interest me. Just more 4/8 chips with very little overall performance improvement.

An 8/16 core Skylake -E chip would def get my interest though, especially if ran cool enough for Mini-ITX.
 
Not bad overclock on those mainstream Broadwell processors if this type of overclock can be expected of them on just air cooling.

I wonder if Broadwell-E will overclock just as good making them a not bad upgrade from Haswell-E.

Disagree - these are bound to be sold at a premium, due to the most expensive IGPU onboard - Iris Pro. These chips are designed for use without a dedicated GPU - something that rules out the majority of users here.

It's horses for courses mate - no room for a dedicated GPU? Then these chips will get you the best onboard graphics money can buy, doubt it's going to be cheap though.

For everyone else who's going to be using a dedicated GPU, 4790k or Skylake or X99 is a much better choice.
 
Quite a few canandian, Czech Republic and eastern european countries are listing the I7 5775C for $380 to 450 (US Dollars). In other words, same price as a 5820k or slightly more expensive.

How you can say that without seeing the performance? You keep making blanket statements based on thoughts not facts :p

We need to see legit benchmarks / reviews before condemning Broadwell :D

We've already seen it's SuperPI scores (from the facebook leak) which are unimpressive, since this CPU is clocked way slower than a 4790k and has 2MB less L3 cache.

Once again, these two Broadwell-C CPU's are not meant to be successors to the 4790k. They are successors to the 4770R (Iris Pro Haswell). Skylake 6700k is the true successor the the 4790k.

Why have written 'Once again, these two ....'

That wasn't the issue, the issue was you saying Skylake was 15% faster than Haswell based on benchmarks we can't confirm. Now you're diverting onto another subject lol.

Until we see legit benchmarks / reviews I expect Broadwell to bring about 5% improvement over Haswell and Skylake 5% over Broadwell.

So Skylake could be roughly 10% over Haswell.

I'm done with this foolishness :p
