Point noted. Then would the 3550 be worth an extra grand?
How does this feature exactly work out?
In my opinion yes OR you can go for its slightly lower sibling the Core i5 3450 ~12500/-. Either ways stick to an Ivy-Bridge set-up now that it is out, no point going for the older Ivy-Bridge / AMD FX- processors --
- actual performance gain over the previous Sandy-Bridge processors is minimal, averaging ~10% -->15% in the most optimistic scenarios;
- gains in efficiency are more profound, thanks to newer transistor 3D-gate design and shift to 22nm fabrication the processor does the same work as a Core i5 of the previous generation with ~30% lesser power --> 77W TDP vis-á-vis earlier 95W.
- you are getting a new build, better to get the latest and greatest instead of older stuff, it is not costing a whole lot more thanks to the $ games going on and poor supply-demand situation.
To answer how the
iGP functions on the Intel processor, you have to understand that it was AMD that went around trumpeting that the future is close integration of CPU + GPU [what they now sell in Llano and Trinity chips]. Intel has always wanted a pie of this market but since the last well... existence of Intel their GPU's were pure malarkey.
So when AMD turned on the heat in 2006 -->07 by acquiring
ATi graphics, Intel decided to up the ante and the first results were the Clarkdale
iGP equipped CPU' which did not go down well [because they were all dual-cores and the
iGP was worst than competing AMD Athlon IIx4 + AMD 785G combos]. So they went back to the drawing boards and came up with a fresh design for the same in their Sandy-Bridge lineup [but once again screwed up by equipping the high end chips with the best
iGP's whilst the lower end offerings got smashed by AMD's Llano APU].
The base differences are --
- the iGP has shifted from the NorthBridge chipset onto the CPU-die;
- th iGP on the Llano had a direct interconnect with the main memory, this meant with faster RAM the performance went up and with poor bandwidth the GPU was starved and would under-perform, Intel did not have this direct linking instead the CPU + GPU shared the same bandwidth and because the CPU demanded more the iGP performance suffered;
- Ivy-Bridge is the refinement of these ideologies and features a more powerful HD2500* and HD4000* iGP with a better architecture and more pixel crunching power per pipeline [and a whole lot more of the same].
*These allow you to play Solitaire while waiting for your replacement graphics card, the Llano and Trinity from AMD steam-roll Intel here and even play most titles on full-HD [minus gratuitous eye-candy].
