I meant that in order Intel to control the whole GPGPU prospect they should stay in discrete GPU market for 4-5 years, they can't do it from the first 1-2 years.
So I said that Larrabee being a 45nm product is a good thing becauce the 45nm tech gives Intel the possibility to move faster than 2 years cycle in the manufacturing process for their future GPUs.
And this is crucial becauce first TSMC from Q4 2005 (90nm) has 1,5 year equivalent cycles and second ATI & NV probably can improve the performance of their GPU per year more in relation with a X86 architecture.
Also in Anand preview of Larrabee technology, Intel said that even the move to 6 cores from 4 brings a not ideal scaling in performance, so imagine what will be with more than 6 cores.
So if Larrabee was to launch at 32nm Intel will have to improve for the next 2 years the performance of Larrabee within this framework.
So you can understand that if (like you said) Larrabee has not a top performance in DX11 (this is the most probable scenario)
For example in Q2 2009 there was 300$ 1GHz 4890 models & 100$ 4770 models,
let's say that the TOP Larabee model in Q2 2010 instead of having the DX11 performance of the future Q2 2010 "
1GHz 4890 model" equivalent
will have something like the DX11 performance level of the future Q2 2010 "
4770 model" equivalent (around half)
So the TOP Larrabee model will probably have the DX11 performance of a Q2 2010 100$ ATI model.
How many years can Intel stay in the discrete GPU gaming market if ATI & NV can increase the performance of their future GPU models much more than what Intel can increase?
With this scenario Intel will be forced after 1-1,5 year to sell products in a price range with a DX11 performance that is way lower than what ATI & NV will have.
Of cource this scenario has 2 presumptions
1.Intel Larrabee is to Launch at 32nm
2.Intel TOP Larrabee model will not have the performance of a 300$ DX11 Q2 2010 ATI model
That's why I said that that Larrabee launching at 45nm can mean good things for Intel's future plan.
