Two physical cores are better than one physical core HyperThreaded for two virtual cores. However, two physical cores are not better than two physical cores HyperThreaded for four virtual cores.Thanks for your information.
I thought hyperthreading is not a new technology, and real number of cores should be better than hyper?
i5 does not support hyperthreading while the i7 does (hyper-threading = 2 execution threads per core, in place of 1)I saw all i7 have 1MB L2 cache and 8MB L3 cache, while i5 750 has the same L2 and L3, so why i7 is better?
Similarly, I saw Core 2 Quad Q9550/Q9650 has 12MB L2, so isn't it better?
+1CPU is not all about the size of cache or clock speed....it's all about architecture of the system
and also i7 has hyperthreading, which i5 doesn't, it should perform better in multi-threaded programs
nope, no i7's will be in retail stores - only base i5'sDoes anyone know if i7 will be sold out of the stores? It seems to be a BTO option off the i5 from the website. Usually this means not in stores. Given all the interest though I thought maybe...
what a miss-leading title...Here is a good thread to read: The i5 doesn't have Hyper-threading and only has 4 cores, i7 does and has 8
what a miss-leading title...
just to clarify: they both have 4 cores - but with hyper-threading the i7 has 8 execution threads (or virtual cores I suppose) while the i5 have 4 execution threads
I was told that it will not be sold in stores. I however can not imagine them not selling it in stores. Don't most of us walk into the apple store wanting the best. I want the best so I have to wait 2 weeks?Does anyone know if i7 will be sold out of the stores? It seems to be a BTO option off the i5 from the website. Usually this means not in stores. Given all the interest though I thought maybe...
From the fine print of the BearFeats article:It does not compare the i5 to i7 .... so
