I can bet your ass it is not. PSP got MIPS architetecture CPU with variable 1-333MHz clock speed, 16/16KB cashes, integrated vector FPU with 2.6GFlops performance plus the second DSP core (video/audio acceleration, effect processing), all coupled with 128-bit memory bus at 2.6 Gbit/s. Look for precious details on http://ps2dev.org/. Overall, it's quite fast and directed specifically for gaming console. And by the way, pixel fillrate of integrated graphics chip is 664MPix/s with 33MPolys/s geometry performance.
For 3DS's supposed CPU go see

It is clearly not "a lot more advanced". Faster, but not by incredible amount. 3DS graphics is much better than PSP one (not in terms of raw performance, but rather capability-wise. Plus more eDRAM), but CPU isn't. And iPhone's Cortex wipes the floor clean with both.
While it's good you know how to look at and compare postive integers with similar units, you fall into a fairly common trap of assuming that the numbers are equivalent.
First off, remember that while the R4000 CPU in the PSP
can hit 333MHz, it's intentionally clocked at 222 because of power and heat.
Second, you would do well to remember that comparing raw numbers like CPU clock and GPU poly rendering becomes highly misleading even between devices in the same generation. I can't be the only one who remembers how Pentium 4s stacked up against Athlons with much lower core clocks. In this particular case, the R4000 design is from the early 90s (these things were in SGI's Indy for crying out loud). While the R4000 does feature a superscalar design, barrel-shifter, and single-clock execution (for everything that isn't division or SqRt); it unfortunately doesn't include many of the common innovations found in the intervening decade. New approaches to instruction parallelism, OOE, improvements to pipelining, multiple ISA revisions.... as you can see, it's hardly a simple apples to apples comparison. And the 3DS has two of these.
Further, The Pica200 is much more powerful than their old marketing pdf would indicate. The updated specs place it at around 400Mps fill and 40Mt at 100MHz.[1] At 200MHz (nominally what Nintendo is packing), it might even best the PS2 (which was difficult to program, but really was a poly-pushing monster. Raw performance only exceeded by the Gamecube, as I recall) and certainly towers over the PSP.
You are, however, correct that the Cortex-A8 is a brilliant piece of kit.

Somehow I think Nintendo just isn't interested in Epic's business
Does Epic make games? Rarely. Does Epic make games worth playing? Not since 1999. That might have something to do with it. :/

That doesn't surprise me, since the Nintendo 3DS has as much VRAM as a graphics card from 1994.
Note the screen scale. Much smaller framebuffer, lower texture resolution, likely a compressed colour space to save bits (555 like the DS?). Also, it manages to do everything much much faster than the Mach-series VGA cards....
