If you are referring to the internal names like Haswell and Sandy Bridge, get out a map of. Obviously the biggest jump came from the 2500K to 3770K (doubling of threads), but the 6700K has a good 15 - 20% higher IPC than the 3770K, plus support for DDR4 means gaming is actually significantly faster on the 6700K, I was quite surprised by the difference. Intel follows a tick-tock model for improving its products. I personally went from a 2500K to a 3770K to a 6700K and the gains were tangible with every upgrade. This plus incremental clock speed improvements with each 'gen' (I'm being kind here) means that you get your ~10% gain in stock ST performance (obviously CFL is a much bigger jump for MT due to a 50% core increase) despite it being the same architecture. This doesn't mean much for enthusiasts running Z series motherboards as you can overclock the RAM anyway, but for non Z boards its somewhat important as I believe DDR4 2133 especially is quite a big bottleneck for say, a 6700K. Processors utilizing Haswell were officially announced and released by Intel in June 2013 as the 4th Generation Intel Core Processor Family, with each Haswell processor bearing a 4-digit number with an initial digit of 4. And news sources from China can be hit or miss.Mostly accurate, though the official memory supported memory speeds did increase with each 14nm optimisation, ie. The tick to Haswell, codenamed Broadwell, will be fabricated on a 14nm die shrink. As it is, we're getting maybe 10% improvement between microarchitectures, and less than that when they do a tick refresh. While I can believe that Intel is struggling with 10nm, I wonder if they really want to have an in-between processor release where the change is marginal. For an elevated experience, pairing Intel Core processors with integrated graphics with the new Intel® Arc discrete graphics solutions deliver even higher performance and more creation. It is a tock and its codename is Haswell. Intel® Core processors with Intel® Iris® X e graphics and Intel UHD graphics bring immersive, visually stunning experiences to laptops and desktops. The "H" series will also come with the new GT4 graphics unit from Skylake and 256 MB of extra cache. When Intel makes a tick, it has the minimum size that can be used to create transistors that are the building. The "H" line will be quad-core processors with TDPs of just 35 to 45 watts. The "H" and "S" processors will have a separate Platform Controller Hub (PCH) chip, unlike the single-chip design of "Y" and "U." The new PCH feature will be support for USB 3.1 interface. Some of the "U" series will have the higher end GT3 graphics with 64 MB of extra cache, while others will use a GT2 graphics unit.

It will use the GT2 graphics core, or the HD 4x00 graphics that came with the Haswell processor. Kaby Lake will have four processor lines, dubbed "Y", "U", "H" and "S." The "Y" and "U" lines are single-chip dual-core microprocessors not much different from Skylake, except the "Y" line will have a power draw as low as 4.5 watts. Kaby Lake processors will be mostly identical to Skylake but there are improvements to be had in TDP and performance. The Chinese hobbyist site claims Intel may postpone the Cannonlake platform, the 10nm die shrink of 14nm Skylake, and release a whole new line of 14nm processors called Kaby Lake. Now it seems the company is facing another delay, but instead of holding off on launches, it has a whole new processor line. Because Broadwell, a tick, was late, it delayed the launch of Skylake, the tock. It took Intel almost a year to get 14nm working, which delayed the introduction of the Broadwell line of chips. Just recently, SemiWiki reported an even further delay, until 2016. Intel was supposed to convert its fab in Kiryat Gat, Israel, to manufacture 10nm chips, but delayed the upgrade until December.
