Intel has introduced new CPUs for laptops based on its mainstream Haswell and low-power Bay Trail architectures. The new chips are updates to existing products in Intel's lineup, and bring slight speed improvements at the same prices as the models they supersede.
The move is in line with
Intel's recent refresh of the desktop
Haswell range. While these are not brand new chips based on a new architecture, they represent improvements in Intel's fabrication processes since the initial launch of processors based on Haswell and
Bay Trail.
According to
CPU World, there are three new processors branded Celeron and one new Pentium at the low end. The Celeron N2808 and N2840 have two cores with 1MB L2 caches, while the Celeron 2940 and Pentium N33540 feature four cores with 2MB L2 caches. All four lack Hyper Threading and are rated with 7.5W TDPs except for the Celeron N2808 which has a much lower 4.3W TDP rating.
Three new Core i5 models and four new Core i7 models have also been introduced. The Core i5-4278U and i5-4308U as well as the Core i7-4578U are low-voltage dual-core U-series parts with 28W TDP ratings and Intel's Iris 5100 integrated graphics. The three H-series i7 models - 4770HQ, 4870HQ and 4980HQ are quad-core parts with Intel's Iris Pro 5200 integrated graphics and a more standard 47W rating. The lowest-end Core i5-4210H has two cores and a 47W TDP rating but makes do with Intel's less capable HD 4600 graphics.
All seven i5 and i7 CPUs feature Hyper Threading, which allows each core to run up to two threads at a time for up to eight simultaneous threads on the quad-core SKUs.
OEM tray prices range from $107 (approximately Rs. 6,435) for the Celeron N2808 to $623 (approximately Rs. 367,467) for the Core i7-4980HQ.
