Intel i5 3rd vs 4th generation?

  • Jason94

    My old Core2Duo needs a upgrade. At the moment I'm thinking about upgrading to Intel i5 3570 (3rd generation).

    Intel is going to release the 4th generation before this summer, but is there a point for me to hang around for it?

    Generation 3 got all the virtualization stuff I need (I'm a windows phone hobby developer so I need virtualization for the phone emulator), and I have a separate graphics card for my gaming.

    I see the leaked overview i5 generation 4 gets the same number of cores/threads and about the same MHz.

    I would say yes there is, every 2 years intel produce a new micro-architecture, you might have noticed that the difference between i5 1st and 2nd gen is very impressive, the same could be expected for the difference between i5 3rd and 4th gen.

    The difference between i5's 2nd and 3rd gen was not huge because both have the same micro-architecture (sandybridge), but mainly the later has a smaller die.

    Read about it here:

    I expect from the future haswell to have good performance increase per clock, and to have much better GPUs, and to have far lower idle power consumption (will benefit laptops).

    Is there a point for you to hang on to it? No one knows, but probably not.

    You should wait for it if you want the improvements in Haswell, want the extra goodies in the new chipset, or need an easy upgrade path to Broadwell.

    Haswell should have the usual 10-15% performance bump over equvilent Ivy Bridge chips. The Lynx Point chipset might have full SATA-III, extra USB 3.0 ports and the ability to control the speed of the ports, and maybe other things that no one knows about.

    The new socket is supposed to be compatible with Haswell's successor, Broadwell, but will the first-gen motherboards be? It's too early to say.

    i am building a new sandy bridge desktop. i want to run 3 to 4 monitors on this system, and would like to have access to quicksync and some of the other optimizations that the intel graphics have to offer. will a H67 motherboard allow me to run the IGP and Discrete GPU at the same time?

    I haven't tried this myself, but my understanding is that as long as:

    • The motherboard itself allows you to keep the integrated graphics enabled with a discrete GPU attached, AND
    • The drivers for the two coexist peacefully in your operating system of choice, AND
    • You have at least one monitor cabled to the integrated graphics

    Then you can use the functionality in question.

    EDIT: I would note that the accelerations offered by the chip are, in theory, available for a discrete GPU to offload to, so down the road AMD/nVidia might make this functionality available (if they bother).
