64-Bit UT2003 [Nov 20, 2002, 4:06 pm ET] – Share – Viewing Comments
AMD and Epic
Demonstrate Power or 64-Bit Gaming has word that: "At Comdex, AMD
demonstrated a 64-bit developmental version of Unreal Tournament 2003 from Epic
Games on a system based on the upcoming AMD Athlon(tm) 64 processor. The
technology demonstration illustrates AMD's commitment to bringing
next-generation, 64-bit computing to the desktop and consumer applications."
The press release offers a quote from Epic's Mark Rein saying this version of
the game will actually be finding its way into people's hands: "We're
planning to ship a 64-bit update for Unreal Tournament 2003 at the same time the
AMD Athlon 64 processors show up on retail shelves."
Slow down there, meatpole. You have no knowledge of how much cache the processor will have - it could easily have twice as much.
Also, since they're releasing a 64 bit fix, you could bet the code is optimized for 8-byte pointers.
One more thing - they tout backward compatibility, so I would bet 4-byte pointers still work just fine. My guess is that the chip can just ignore the upper half of its adress space (or applications can, at least).
