The leaked slides of the Q3 and Q4 2013 desktop processors roadmap from Intel show a lot of processors to be released. Intel would be checking out the untested waters of BGA chips with Haswell during Q3 2013.
By the end of this year, Intel would be launching newer processors under Pentium and Celeron branding, followed i5 and i7.
The slides also show detailed specifications and time frames for Ivy Bridge-E HEDT processors, including the newest flagship.
As far as Q2 2014 is concerned, there will be a Haswell refresh for the existing processor lineup as mentioned below, most likely with higher base clocked Haswell processors unless Intel plans to out the Broadwell lineup. But as of now, the news is that Intel pushed Broadwell towards 2015.
Coming to Q3 and Q4 2013:
This will have 2 Pentium SKUs- J2850 Quad Core base clocked at 2.4 GHz and J1850 Quad Core with base clock of 2 GHz, 2 i5 SKUs and 1 i7 SKUs while Celeron J1750 will be base clocked at 2.4 GHz with a dual core. These BGA chips will feature 10w TDP.
i5 chips 4570R and 4670R will both have a quad core with Intel Iris Pro HD 5200 graphics base clocks of 2.7 GHz and 3 GHz, followed by i7 4770R with 3.2 GHz base clock speed and same graphics as i5. Both of these chips has TDP of 65W.
The Ivy Bridge-E will have 3 new processors: i7 4960X, 4930K and 4820K. 4960X will have 6 cores with 12 threads based clocked at 3.6 GHz with 130W TDP, whereas i7-4930K will have 3.4GHz with the same amount of cores and threads as the flagship, but with 12MB Cache. i7-4820K will be clocked at 3.6 GHz with Quad Core and Hyper Threading.
Though these will be working with the existing x79 platforms, there would be a new chipset that will be introduced along with these chips.
