Intel Broadwell Core i7-5775C & Core i5-5675C released mid-may

Why the change from K to C to denote whether or not the processor is unlocked? That seems like a pretty pointless move to me.

hehehe, speculation on the internets. 🙂 Will upgrade at least for the new motherboards

Who knows, probably only some kind of marketing think, or maybe they will use K for something different in the future. I was wondering quite the same. It does not have much use I guess, then again, who cares as long as we all know it's C from Broadwell on.

Man I never saw that the C meant the same as the K based CPUs. Very interesting that Intel would change lettering and terminology like that. Also it is possible that the C based CPUs might be very Overclockable.

We saw in Tj's thread that Intel will name Skylake i7 6700k and i5 6600k so its interesting why is it 'C' this time around. I would also like to see how overclockable are these CPU's.

Looks interesting, although I dont like the slower clocks. By interesting, I mean that I might upgrade my CPU when Skylake comes out, as I want to go with water cooling, but I dont really have enough space in my case to go add more than 2 radiators, one of them being small, 140mm, so when it comes to that, low TDP is a good thing... EDIT: Meant to say Skylake instead of Haswell.

Well it's all speculation at this point but speaking from personal experience moving from an 8350 to a 4790k I actually saw a drop in performance in multi-threaded applications even tho the 4790k is the faster chip the extra cores on the 8350 did make a difference in multi-threaded apps, if DX12 is all it's cracked up to be then I think having more CPU cores will have a considerable impact but yeah it is all speculation, still doesn't change the fact that we've been using dual and quad core processors for years.

Whether extra physical cores improves performance or not, depends on how the software is coded. If the application is coded to use 1-4 cores, having 5+ cores will make no difference at all.

The "C" is just marketing. They want an additional tier of processors for the main stream. "K" is for enthusiast branding. Have all the ram controllers only been rated at 1600? Just seems odd that with all the DDR3 speeds in the channel, the memory controller is only rated at 1600. My feeling is that these are only targeted at the main stream market.

If a C2Q Yorkfield lasted 4-5 years then no doubt it will be the same for these newer i7 cpus with 8 threads. btw dx12 is build around 8 threads, anything more and it doesn't scale so well.. For example Mantle can use more then 12threads.

Exactly my point, DX12 will spread the load across CPU cores more efficiently compared to DX11, I'm not expecting double performance but I think we will see significant improvement but yeah it's all down to how well the game is optimized to take advantage of it and I'm fairly sure developers will want to take advantage of DX12' capabilities in future titles and I think once that happens we will see a rise in demand for more CPU cores.

@TJ Easily. Heck mine is still doing well after 6 years :P

Idk, i5 6600k will still be a 4core 4thread CPU and it will probably be faster than any past generation i7, atleast in gaming. Higher per-core performance and higher core clock is still the king.

Thats a very good point. I've personally been getting hung up on why they elected for skylake to be max 4 core, but in reality if those 4 cores are superior to the 6 cores of the 5820/5830, why not upgrade? But then again, I'm coming from the "dear god release something worthwhile to upgrade to" camp.. been too long with this z68 chipset 🙁 but then again, again, that's a good thing also.. as sandy bridge still holds it own.

Every Intel DDR3 memory controller only supports DDR3-1600. That's the limit of "official" memory support.

well I wonder how long this 3770k will last for gaming with dx12 coming up. I'm not too eager for a cpu upgrade right now.

I wouldn't worry about it really. You've got another 1-2 years to go.

Wondering this myself. It seems to also indicate it will only take ddr3l

This is perhaps Intel's most underwhelming processor release in memory. Let me think...do I want to sell my OC'ed i7 4790k (its now at @4.6GHz 24/7) which is so fast it still amazes me everyday, and replace it with a shiny new Broadwell i7 5775C running at 3.3GHz and 2MB less of L3 cache? hmmmm let me think........................................................................................NO, I'm good, but thanks anyway Intel.:bang:

This controller only supports DDR3L unlike the previous Haswell IMC which supported regular DDR3 and DDR3L. What nobody is saying/maybe not aware of is that these two CPUs will not even POST with regular DDR3 memory, you actually will need DDR3L, at least on the current boards. The upcoming boards/refreshes may be able to boost with regular DDR3 As for L3 Cache, one shouldn't be attached to the cache size as it tells you nothing about performance in isolation. Losing out on 2MiB of cache to gain 128MiB of L4 cache is something I'd do any day.

Depends, I think that L4 is only for igpu..

I'm still rockin with socket 2011- i7 3930K 6core, since 2011 Do i need to upgrade sometime soon?

I think we should wait to see the first samples of the Skylake family and then answer this question 🙂 I have the 2500K and it is still performing decently..
