Haswell IGP 128MB will “Crystalwell” integrated
This week intel finally revealed its specifications Haswell microarchitecture that will be based in the future fourth-generation Core microprocessors for socket LGA 1150 (versions for workstations and servers will use other sockets yet undisclosed).
Haswell has been redesigned to deliver higher performance per cycle while possesses several technologies aimed at reducing consumption, but without doubt if there is an area that has grown Haswell is the IGP, epitomized: Denlow GT3 will have a total of 40 EUs (now HD Graphics 4000 “Carlow GT2″ Ivy Bridge has 16 EUs), where each EU consists of four ALUs, which play the role of shader processors.
Additionally some CPUs for high-end laptops will incorporate dedicated graphics memory and integrated on the same substrate the CPU, which is known as Crystalwell , and will be available in configurations up to 128MB with a 512-bit bus , this is the type eDRAM memory and is presumed to have a bandwidth similar to that of GDDR5 128-bit bus.
In Anandtech estimate that accompanied Denlow Crystalwell gt3 will double the performance of Carlow GT2 (HD Graphics 4000), plus an estimated Denlow GT3 for Ultrabooks will yield 30% higher than for Ultrabooks GT2 Carlow. Additionally it is estimated that the yield per cycle Haswell CPU will be about 10% higher than the Ivy Bridge CPU.
