    Reviews say that the HD4000 on Ivy Bridge has 199% performance increase in certain graphical benchmarks. Despite the well-known fact that INTEL is just playing with statistics which means there probably won't be that much of an improvement over HD3000 in the real world, I still hope that I can at least play SC2 in Med/High.

    Any thoughts?

    And can anybody please tell me what's the possibility that I can use my eGPU with the Ivy bridge model?(which is not compatible with the newer T420 & X220 due to the BIOS limitation)

    Thanks, guys.

    X220 bios 1.24 fixes the TOLUD issue so can now have 4GB+ RAM eGPU implementations. See Re: Request to fix TOLUD in newer BIOS files - Page 14 - Lenovo Community for more details.

    It's all pure speculation until the chipset is released and benchmarked.

    I think they said 40-50% better, realistically, while CPU's are like 15-20% faster. But the biggest thing is full implementation of 3D transistors (tri-gate) which drastically cut power consumption so you will experience better battery life.

    Intel might improve the technical (theoretical) capability of their integrated gpus and score better with benchmarketing suites...

    But so far for actual users the quality of their drivers are mediocre or worse: more glitches than ati/nvidia, less compatibility (esp non-mainstream/older titles) and clearly inferior rendering quality.

    I totally agree. We are not talking about collecting arts here so don't hesitate to buy a piece of electronics when you need it.

    I can't vouch for the T420 but this text in the T420s BIOS 1.30 readme file suggests that the fix has been applied on the T420s. Take a look in the T420 BIOS readme.

    I have the Vidock 4 plus and I can verify that it does work with the T420.

    Great. Any chance you can do volunteer to do some extensive benchmarking like these but at pci-e 2.0 link speed? I understand the VD4+ negotiates a pci-e 2.0 link with the T420 so should deliver some impressive performance.
