Thanks for the interest, guys! I was just waiting on Xbitlabs as the final input needed before I could go ahead and rate the cards, like I usually liked to do in the past. With the R9 290 cards, it seems that they need more data than any other cards before it in the past, due to different results from different reviewers (some using cold runs, while some used warmed-up results, some starting to review them with PhysX on high, and Toms showing a bad retail sample that had severe throttling issues..) Sometimes Xbitlabs is just a couple weeks late to the spotlight, but this time it seems to be taking longer than usual.
As for the 280X, it's just a few percent slower than 7970GE. About 3-4% overall - it's 246 VP for now, without Xbitlab's "final touch" on the ratings..
List updated with R9 280X @ 246 Voodoopower!
Edit - also added R9 270X, rated @ 187 VP
After Tomshardware was perhaps the only site to report a huge, massive variance in performance between the retail R9 290X and the press 290X for a while, LegitReviews also reported a similar issue not too long ago: http://www.legitreviews.com/amd-radeon-r9-290x-press-sample-versus-retail_129583
Is this an extremely random (rare) issue, or is it a fairly common one? I do not have much time to read the forums right now - input would be much appreciated.
Thanks. How common/rare is this?
Does flashing the BIOS (although it has 2 different BIOSes with a hardware switch) void the warranty?
*Edit - Since the warranty covers Uber mode, and the fact that this does not affect Uber mode but only the Quiet mode, with the ratings list only doing one rating per card, the Uber mode will be used for 290X rating. Yet, I'll still derive a rating for Quite mode in a post here in this thread, just for the fun of it (like I did for a warmed-up Titan at stock default setting).
I will be getting a evga gtx 780 superclocked with 6G vram in a few days and wanted to ask can these be Oc'd even more?
Or did the factory already find the sweet spot(aka LIMIT) on these?
