Two choices:Any idea what the 4771 will bring over the 4770?

A boring 100 MHz increase? Why the hell they didn't called it simply Core i7 4780 to be consistent with nearly all other models?

At least "+1" to the model number for "+100MHz" to the base clock is much more sensible than "+1060" to the model number in exchange for "+700MHz" base clock.
So going from Sandy Bridge (January 2011) to Haswell Refresh (Q2 2014) we will only have seen something like 8% (SB->IB) + 8% (IB->Haswell) + 3% (Haswell Refresh) = 19% performance increase in more than 3 years?
Is there even anything on the roadmap further ahead that is likely to bring substantial performance improvements? Broadwell seems to be mostly about lower TDP and better IGP again (like Haswell)? The details on Skylake are not that well known though, maybe it will bring some CPU performance improvements? Or is the Desktop CPU development basically "completed" now as far as CPU performance goes. This is more or less as good as it gets performance-wise. We just have to get used to it?
100 Mhz / 3400 Mhz => 3%. Assuming the 4771 is just a 100 Mhz CPU frequency increase over the 4770.How did you get Haswell refresh to 3%?
Fair enough. It should actually be 1.08*1.08*1.03 => 20.1%. But since the difference was so small I didn't bother being exact in my previous comment. It was just an approximation anyway.Also you cant just say 8+8+3 and get 19% (assuming the numbers you came with.). It would be just over 20%.
New instructions is the way to higher performance. Over time the IPC for IB vs Haswell will only increase in the favour of Haswell.

Let's hope so. But we have unfortunately been disappointed before with the real life benefits of new instructions that have been introduced.
Most people don't use their computer to run Linpack. They are interested in real life performance increases...Try Linpack on a Nehalem vs SB vs Haswell and tell me what you get.

What corrected chips? There is nothing wrong with Haswell so nothing to correct (technically speaking there is always some errata but this is it when it comes to performance). Maybe if you are referring to IHS<->die contact, there is a room for improvement.haswell is gonna be around a while, itll be a good upgrade once the corrected chips are out...
