I'm talking about MSRP to MSRP, if they price new GPU's against EOL GPU's they will quickly end up at a Zero $ sum.
Its why Nvidia stopped discounting EOL GPU's, tech jurnoes started comparing EOL pricing against new, Nvidia being as switched on and ruthless as they are just said "right then, i'm not playing along with that game"
Even AMD held out for quite a while reducing the price of its upper midrange, like the 6750XT, the 6800 and the 6800XT.
I understand the tactic from tech jurnoes point of view but they are never bright enough to see beyond their own agenda, i mean some of them even compare them to equivalent used GPU's when they are only 15% cheaper, 3 year old card with an unknown history and no warranty, this is bad consumer advice and its the reason why used GPU's are priced so stubbornly high.
Right now i'm seeing £400 to £450 used 6800XT's, Hardware Unboxed would tell their audience to buy those instead of a brand new 7800XT for £500, it almost seems spiteful because the 7800XT isn't £400. really very bad consumer advice for the sake of sticking it to AMD.
Anyway, while i don't know where these none XT GPU's would fit in when it comes to pricing i think having them makes a certain amount of sense, they would be salvaged parts, parts that have been RMA'd and the still good cores rebinned and reused. They all do this as a way to recover RMA costs and not waste good parts.
By now AMD will have a collection of RMA'd 7700XT and 7800XT chips, the 7900GRD are salvaged 7900XT's and 7900XTX's.
