So we now have 32nm duals in various flavours of 1156 and 1366 have been given 32nm hex. But where's the "tock" for the i5-750??? 760 is supposed to launch soon, but I don't understand how only budget and high markets get the die shrink. Surely a 32nm i5 with four cores (hyper-threading or not) would be an immense overclocker and THE chip to have for a lot of people?
32nm is still ramping up - I think Intel would probably love to do 32nm everything, but thats just not the way fabs work unfortunately.
According to intel, there will be no 32nm quads. That is reserved for sandy bridge which would make an appearance by the end of 2010 or early 2011.
i too, would really like this. As for why: Intel was allowed to engage in anticompetative behaviour for a long, long time, putting AMD so far behind that intel has no competition in the space of the 750, so they have no reason at all to upgrade it.
There are 32nm quads, but they're Xeons and (I believe) only work on Socket 1366 Dual motherboards, which generally cost over £200 and don't offer any overclocking.
Really, it's a workstation core (Westmere) so there's no real reason for Intel to sell them to consumers, especially since 45nm Intel chips are still the market leaders.
Yeah, I get it now, Rofl's on it. It just seemed odd, that both ends had received a tock, but not the mid-range chip. A quick Wiki and the Sandy bridge situation becomes clear. What IS interesting, is the quad channel DDR3 that appears to be required for socket 2011. Given that 1366 is triple channel, I had been assuming the new high end would move to triple channel. Quad hadn't even occurred to me. What that could potentially mean, is that people with 4gig of 1600mhz DDR3 now, could maybe keep it if/when they transition from 1156 to 2011 and just buy the same again. Could be a significant saving compared to those moving from 1366 to 2011. That said, if you're on 1366, you'd probably just stick with triple channel and slap a 32nm hex chip in there when the price is right. Of course, if you want to move from 1156 to 1155, you can just keep your RAM anyway....
They have no reason to release a 32nm of i750 as it's still flying off the shelfs Amd has no real competionto intels medium range The low end chips whilst overclock well are still not gonna replace the 750 for most of the Market
Its not really happening on 1156 and maybe not even on 1366. Thats the thing about p55, what is out now is all that will ever be out. No upgrade path
If you read the stuff on wiki, it appears that there is no tock for P55. Sandy Bridge is a tick (so they've missed out the die shrink for P55) and Ivy Bridge is the 22nm tock. Obviously, it would be silly to take wiki as gospel, but the Ivy Bridge tock is listed as the same socket 1155. Compare that to P45 with 65nm chips moving to 45nm and it seems to be not as tasty. If possible, I'd prefer to buy on the tick, so the die shrink is available as a future option. Wonder what everybody else thinks.....
I personally would buy on the tick. The tock is nothing significant, it is the same architecture. What matters most is clock speed and instructions per clock. A die shrink would decrease heat, power consumption, and thus increase overclocking only slightly but not by huge margins.
Tock, you mean? The overclocking is fairly significant with 32nm. You'd be lucky to get a 45nm quad core to 4.2GHz stable, but 4.6GHz is routine with the 980x, which packs two more cores in. Granted, these are cherry picked chips (with the lower ones going to servers) but still, even the clarkdale chips overclock further.
