Our colleagues of PC Online have tested a Pentium E2160. Based, like the Core 2, on the Core architecture and using the Socket 775, the Pentium E singles out from the E4x00 with "only" 1 MB of L2 cache, instead of 2 MB for the E4x00.
In practice, the impact on performances doesn't seems to be that significant and compared to the Pentium E2160 and Core2 E4300, both clocked at 1.8 GHz, they measured performances gaps generally inferior to 3%. The most important difference was with Serious Sam2 at 7%. This isn't catastrophic and this line of processors will have an interesting performance / price ratio since the E2160 release price in June will only be of $84, instead of $113 for the E4300. |

One quarter away from the release of the first Opteron Barcelona, AMD announced two new Opteron 3GHz, the 2222SE and 8222SE. Unlike the 1222 SE, compatible with the Socket AM2, these new CPUs use the Socket F. The 2222 SE can be included to dual processors configurations and the 8222SE to four or eight processors configurations. With these new products, the Texan manufacture has reduced the TDP from 125 to 119.2 Watts.
The support of 3GHz frequency with two cores and the Socket F isn't an innovation by itself for AMD. With the exception of a few watts and the support of registered memory, the Opteron 2222SE really looks like an Athlon FX-74. |

Intel has discretely released the first two Core 2 Duo Ultra Low Voltage processors. Named U7500 and U7600, they are based on a Meron core and run at 1,06GHz and 1,2GHz. They use 533MHz FSB which is half of the Core 2 Duo E6X00.
The TDP of these processors falls to 10 Watts and that deserves to be underlined since the Core 2 Duo Mobile T5500 (1,66GHz), for example, has a TDP of 34 Watts and the E4300 (1,8GHz) of 65 Watts. Bearing in mind the level of performances expected and the low power consumption, these processors will of course be of great interest for ultra portable laptops, tablet PCs and will replace the ageing Core Duo U2500. |
