dual core 2

será k este tipo de processador já trabalha a 64 bits ou não?!

[Messerschmitt]

isso são os "quad cores" da intel certo? o Tanglewood ou Tukwila certo? isso não sai só em 2007/2008?

Quanto aos actuais Dual Core, tanto o Pentium D como o Athlon são 64.

Core duo nao dual Core 2

Intel Core 2 Duo / Extreme (Conroe) desktop CPU was released on July 27th on a 65nm process. Conroe is a dual core CPU based around the Merom architecture but optimised for the desktop market by removing some of the power constraints from Merom in order to increase performance. Like Merom, Conroe features a 14-stage pipeline and will be a 4-issue core. Conroe additionally features SSE4 support, virtualization capabilities, LaGrande technology and 64-bit capability in addition to EDB, EIST and iAMT2. The standard edition CPUs will feature a 1066Mhz FSB speed, with the initial members of family being as follows:

E6300 (1.86GHz), $183
E6400 (2.13GHz), $224
E6600 (2.4GHz), $316
E6700 (2.67GHz), $530
X6800 (2.93GHz), $999
E4300 (1.8GHz, 800Mhz FSB), Q1 07

Preliminary benchmarks show that the top of the range Core 2 Extreme 6800 outperforms an AMD FX-62 by 17.5-26% in Office benchmarks, 15-25% in gaming benchmarks and around 25-30% in Media Encoding tests.

Não, esses Dual core2(ou core 2 Duo) são a evolução dos actuais dual core para portáteis(se não me engano).
Como já foi dito por aqui os de 64 bits são o Pentium D ou AMD Athlon.

Nop, para portateis sai este mês de setembro ;).

Intel Mobile Core 2 Duo (Merom) processor, the successor to Yonah and part of the Santa Rosa platform, is expected to be released in September on a 65nm process. Merom is the Mobile equivalent of the desktop Core 2 Duo, and contains an identical featureset although the FSB runs at 667Mhz rather than 1066Mhz for power conservation. Merom is a Dual Core CPU combining the architecture of NetBurst and the Pentium-M to achieve both high performance and lower power consumption. Merom utilises the FSB and EM64T of NetBurst, but is largely based around the Pentium M architecture. The CPU is a 4-issue design (compared to the 3 issue cores of the Athlon 64 and Pentium 4 architectures) with a 14 stage pipeline - significantly shorter than that of NetBurst CPUs (from 20 in Willamette to 31 stages in Prescott). The shorter pipeline will ensure that Merom and it's derivatives will not clock as high as Precott, but it will likely clock as fast or faster than the Athlon 64 - i.e. around 3Ghz. However, the IPC of Merom is likely to be better than the Athlon 64 due to it's 4 issue superscalar design and vastly better than the P4.
Merom features 4MB of L2 cache shared between the two cores and a direct L1 to L1 cache transfer system between the L1 caches of each of the cores to improve performance. Merom also features a number of enhanced prefectching schemes to improve cache utilization. Merom will feature SSE4 support, virtualization capabilities, LaGrande technology and 64-bit capability in addition to EDB, EIST and iAMT2. The initial members of the Meron family are:

T7600 (4MB L2, 2.33GHz), $637
T7400 (4MB L2, 2.16GHz), $423
T7200 (4MB L2, 2.0GHz), $294
T5600 (2MB L2, 1.83GHz), $241
T5500 (2MB L2, 1.66GHz), $209 - Q4

The performance of Merom is around 5-15% higher than Yonah with the roughtly the same power usage (slightly lower in some cases).

quero comprar um portatil, preciso dele para apresentações power point, word, excel, um pouco de net e pouco mais, ou seja preciso de portabilidade mas, não de grande potência, k devo comprar? os centrino k estão a descer de preço, os dual core ou um 64 bits?!

[Neruson]

se puderes esperar e tiveres €€ espera então pelos Core2 duo, senão compra um dual core normal uma vez que estão a tormar-se a norma no mercado.

[Mysterious]

Depende muito do que estas disposto a gastar.

Se queres algo novo/novidade e estas disposto a gastar bastante dinheiro vai para o Intel Mobile Core 2 Duo (Merom). Se não quiseres gastar muito vai para um centrino/dual core normal, agora é uma boa altura para os comprar devido ao lançamento do Merom.
