Prices of Intel "Haswell Refresh" CPUs
Apr 14, 2014: Intel today added brief specifications and prices of all "Haswell Refresh" desktop and mobile microprocessors to the official pricelist. Built on "Haswell" architecture, upcoming products will not have any new microarchitecture and power optimizations compared to last year's products, and their only advantage will be slightly increased clock speeds. According to known specifications, many "Haswell Refresh" CPUs will be clocked 100 MHz higher than the Haswell 2013 lineup, which will result in up to 2% - 5% better performance, much smaller than we got used to in the past three years.

Intel Haswell Refresh CPUs to launch in May
Apr 12, 2014: Digitimes reported this week that Intel Haswell Refresh processors will be available next month. That information confirms older reports, like the one published by Hermitage Akihabara back in March. According to Digitimes, Intel originally planned to launch microprocessors in April, and follow with the 9-series desktop in a month. The latest plan is to launch the CPUs together with new chipset in early May. Hermitage Akihabara provided launch date of May 11.

Clock speeds of Haswell Refresh CPUs confirmed
Apr 02, 2014: Intel prepares to refresh Haswell desktop processors in the second and the third quarters of 2014. The "K" CPUs with unlocked multiplier are expected in Q3, and the microprocessors with locked multiplier will be released a quarter earlier. It was reported that the non-"K" chips will run a bit faster than current generation of Haswell products, and they will be compatible with existing 8-series and future 9-series chipsets. In February we published complete list of Haswell Refresh processors, that will be launched in Q2.

Pre-order prices of Haswell Refresh desktop CPUs
Mar 02, 2014: Last year Intel launched first "Haswell" desktop processors, that boosted performance of the CPU side by up to 10%, and significantly raised performance of the integrated GPU. This year will be less exciting as the company does not plan to introduce new desktop architecture. Instead, Intel will offer products, based on a year-old Haswell core. Preliminary specs of "Haswell" refresh CPUs indicate that almost all of them will have 100 MHz higher clock rate compared to their predecessors.

Some details of "Haswell Refresh" desktop CPUs
Feb 18, 2014: Next quarter Intel is going to launch a bit faster models of Haswell-based processors for LGA1150 platform. It is expected that the company will refresh complete desktop lineup, starting from low cost Celeron microprocessors and up to premium Core i7 CPUs. All in all, more than 20 different SKUs will be released. We already reported on some of these models, but now we have a complete, or almost complete list of these processors, including their clock speeds.

Intel to refresh Haswell desktop lineup in Q2 2014
Jan 14, 2014: Rather than transitioning to new architecture this year, Intel plans to refresh current desktop lineup with slightly faster versions of Haswell-based CPUs. We already reported on Core i5-4460, i5-4590, i5-4690 and Core i7-4790 parts, coming in Q2 2014. According to Digitimes, the refresh will not be limited to Core i5 and i7 products, and we will see new Core i3, Pentium and Celerons as well.

Specifications of Haswell Refresh CPUs
Dec 12, 2013: In the past few years we got accustomed to Intel launching new microarchitecture each year, using new technologies and core enhancements, as well as clock speed increases to boost performance of each new generation of chips. The things will be slightly different next year, because, with the exception of some unlocked Broadwell-K models, desktop Intel microprocessors will still be built on Haswell architecture, and the only new features will be introduced in 9-series chipsets.
