Official developer site Forum Nokia has published its detailed tech spec pages for the Nokia E51 and the Nokia N95-3 NAM, aka the American N95. Amongst other things, it reveals that the E51 has 96 megabytes of RAM (with 50 MB free for user applications), while the N95-3 NAM has 128 megabytes (with 81 MB free for user apps).

The E51 has a single CPU running at 369mhz. The N95-3 NAM has dual CPUs running at 332mhz, the same as the Euro N95.

Generally the E51 seems very similar to other recent mid-range S60 phones such as the 6120 Classic, 6110 Navigator and 5700, but the E51 has over twice as much free RAM and a higher capacity battery.

The American N95 seems pretty similar to the original European N95, but the American N95 has four times as much free RAM and a higher capacity battery.
