On New3DS models, there is instead 4x MPCore, 4x VFPv2, and 268-804MHz CPU.
On New3DS models, there is instead 4x MPCore, 4x VFPv2, and 268MHz CPU(see below for more details on clock-rate). The New3DS ARM11 also has additional cache hw.

The above clock-rates were calculated by calling svcGetSystemTick in sets of 5(call it, execute svcSleepThread for 1s, then call it again), then the average of those were calculated. The clock-rate listed above applies for *all* 4 New3DS MPCores.

New3DS exclusives are able to clock the CPU at 804MHz, but this appears to be limited to the currently running application/app cores. Timed by running svcGetSystemTick on either side of a long idle loop to stay in the current process context. svcSleepThread + svcGetSystemTick implies a tick counter running at 268mhz in this mode.

On New3DS: when Home Menu is active, the system runs at 804MHz. For everything else, it's 268MHz, except when the app(let) has the required flag set. See [[NCCH/Extended_Header|here]] and [[PDN_Registers|here]] for details.
