From AnandTech:

Recently we received confirmation that the first retail samples of ATI’s R420 (AGP Radeon X800) will debut April 26 as Radeon X800 Pro. NVIDIA’s NV40 (GeForce 6800) officially launches April 13th, but retail availability will occur around April 26th. Notice the NV40 product to be released April 13th is GeForce 6800, not GeForceFX 6800. ATI’s naming scheme for R420 has been closely guarded as well, but the open term we hear from vendors is “Radeon X800.”


What seems highly unusual is the scheduled introduction of Radeon X800 XT on May 31st; only a month after Radeon X800 Pro’s unveiling. Recall that Radeon 9800 and 9800 XT were launched six months apart. We can speculate ATI has either changed their marketing strategy, or the difference in performance between R420 and NV40 hastens ATI’s release schedule. Further inspection of the ATI roadmaps reveals that “Non-Pro” Radeon X800s are absent. Perhaps “XT” has replaced the “Pro” Radeon series, and “Pro” thus replaced the “Non-Pro” Radeon series. Even though the initial launches of Radeon X800 will use 256MB of GDDR3, before the end of the year we also anticipate a 512MB revision. Furthermore, we will almost certainly see Radeon X800 SE with 128MB of DDR1; which will also debut with much a lower clockspeed.

ATI and NVIDIA should just give up and start using Capcom’s naming conventions. I don’t know about anyone else, but I’d totally buy an ATI Hyper Radeon EX II + Alpha Championship Edition card. And don’t even get me started on the Neo GeForce X Network Transmission III SE+.
