Neoseeker published a review of Intel's E2140 & E2160 CPU's

Intel is now gunning for the dual core low end now, an area currently dominated by the AMD 3600 X2 and 4200 X2 processors. With the excellent microarchitecture of the Core 2 Duo, Intel is betting on the E2140 and E2160 still performing better than the low end AMD parts; basically betting that the microarchitecture will overcome the crippling effect of the 800MHz FSB that the E21xx series are targeted for.
