    Yes, it is from one point of view.
    Raw CPU power (MIPS) equals to Peg2 G4/1Ghz. My 1.33GHz Peg is about one-third faster.
    Next, as you said, Sam lacks Altivec. Big malus for lame, mplayer, 3D and so.
    Sam also has slower CPU write to VRAM (182 vs 223 MiB/s)

    But:
    Sam has faster RAM (DDR2 vs DDR), faster SATA (PCI 66MHz vs 33MHz), faster write to VRAM with DMA (600 vs 184 MiB/s)
    Also overall HDRLAB gfxbench2D is better (7595 vs 3341 pts with overclocked Peg2), Tower95 is a little faster (34-35 vs 33)

    So it is not easy to say who is faster. I can benchmark it, if I have Sam. ;-)
    Sam have from my point of view very big advantage: with AmigaOS and RX card there is UVD, Unified Video Decoder, where decoding is made completely by gfx card. Peg2 lacks it.
    AmigaOS3: Amiga 1200
    AmigaOS4: Micro A1-C, AmigaOne XE, Pegasos II, Sam440ep, Sam440ep-flex, Sam460LE, AmigaOneX1000
    MorphOS: Efika 5200b, Pegasos I, Sam460LE, Pegasos II, Powerbook G4, Mac Mini, iMac G5, Powermac G5 Quad
