Actually Intel are selling retail kits that contain both a P4 CPU & 2 Samsung RAMbus sticks.
Samsung has in fact got a multi-bullion dollar contract to supply Intel with RDRAM.
As well as them being needed for Intel's P4 kits, Intel has a huge assembly factory in Singapore, where it makes complete computers that then get sold to other OEMs & re-badged (officially its a different company, it just so happens to be wholey owned by Intel).
That's why Samsung settled its Rambus law suit. The other 3 RAM makers that settled with Rambus, settled because they either had big Rambus contracts; or were involved in the Sony PS2 industry (Toshiba), which uses Rambus; or were planning to sell of their fabs or RAM divisions & didn't want law suits hanging over their heads. The other 12 RAM makers that haven't settle, I doubt ever will, because they have no reason to settle & its doubtful that Rambus's patents will stand up, if tested in the courts.
As far as clockability, memory bandwidth &
SSE2 (Screaming Sindy) the P4 flys, but as far as everything else is concerned it's
worse than a equilivantly clocked
Athlon or
P3.
So for current software the P4 is a waste of good money, it will only be utilised by its full potential through the use of re-compiled new software. Even then only Video encoding codecs would give you the time saving worth the re-compile. As far as 3D productivity software where repedative simple calculations are involved, its big cache RISC CPUs such as Alphas that are the go, even a P2 Xeon would be better than a P4 (well that's what my draughtman mate told me).
