Intel to launch Core i5 on 6 September
Roadmap details have emerged revealing Intel's desktop-processor launch plan for the coming months.
September will see the debut of the Core i5 mainstream Nehalem-class processor, along with a pair of new Core i7 parts.
The i5-750 will run at 2.66GHz, though its auto-overclocking ability can push that to 3.2GHz when apps demand it and as long as it doesn't overheat the system. The 750 will support DDR 3 memory running at up to 1333MHz, and it'll contain 8MB of L3 cache as all Nehalems do.
It will support virtualisation, but only as far as aiding virtual machines - Intel's VT-x technology. The new i7s, the 860 and the 870, will also support VT-d, Intel's extension of virtualisation that gives virtual machines direct access to the host's I/O subsystem.
Speaking of the i7s, they'll be stated to at 2.8GHz and 2.93GHz, respectively, though in each case they can overclock to 3.46GHz and 3.60GHz. Both will use HyperThreading to double the logical core count to eight - a feature the Core i5 lacks, it seems.
All three CPUs will have a power envelope extending to 95W. They'll go on sale on 6 September. The i5-750 will cost $196, the i7-860 $284 and the i7-870 $562 - that's per processor when purchased in batches of 1000.
Further Core i5s will debut in Q1 2010. ®
if the core i5 had HT then there would be little to distinguish it with the i7 performance wise. my guess is dual vs tri-channel memory will only be 5-10% difference.
i5 CPU £120
DDR3 4GB 1333 £50
AMD 40nm GFX DX11 £100-£150?
Can't see how that's "fail" in any sense of the word. Native quad core is pretty much always going to trump dual core with HT so there's still going to be a performance advantage to going for a (presumably) higher priced quad i5. Although how much of the additional processing power will actually help is debatable, seeing as the duals will (presumably) have better "turbo" modes.
Can't wait to see how these are going to perform, my PC is predominantly used for gaming so it could well be that the dual i5 will be an equal or better performer in that respect (better turbo for single/dual threaded games, and HT for those games that can spread over 4 threads). The integrated PCI-E controller will also be intruiging, unless of course future graphics cards can saturate x8 x8 bandwidth in crossfire/sli, then there may be some slight "fail" albeit in a totally different area.
Core i5 and hyper-threading
the Core i5 dual-core has hyper-treading but the Core i5 quad-core does not have hyper-threading
Seems a very reasonably chip still
Lets face it, its going to be very unusual workloads that will tax 4 cores, let alone take advantage of the 8 cores you get with hyperthreading. (Database servers, Well loaded Web Server - the only desktop task i can think of would be video rendering)
It seems these are likely to be dual rather than triple channel DDR3 - guess we'll have to wait for benchmarks to see the performance impact there.
If its a bit cheaper than the I7, it could well be a winner. I've been holding off on upgrading (Lets face it, core2duo / quad have been looking like old designs for a while now - how long have AMD been free of the front side bus?)
cool! thank ü intel icpu
