Stupid answer: No, otherwise they'd have the same name :-)
The R8000 was some kind of CPU hack which SGI came up with when the R4400
performance was begining to look bad in comparison to the Alphas and the
R10000 project still would have taken quite some time. It was featuring
roughly the integer performance and twice or trice the fp performance of
a 250MHz R4400 while running at just 75 - 90 MHz. It was used only by
The R7000 is kind of a successor to the R5000 featuring roughly R10000
performance but at a much lower price. This was developed by either
IDT or QED mostly for embedded purposes.
