According to fudzilla
the GT520 will be rebadged as the GT620 for retail/e-retail. Let's hope AMD doesn't follow suit. Indeed the low-end discrete GPU market is going to go extinct soon with IGP's getting better and better with each new generation. Where that cutoff point will be for 28nm GPU's is still unknown to me.
@Forge: I referenced the Anand article above because it compares a few of the current most commonly used GPU's for HTPC's IMO. I didn't see however where/if Anand bothered to mention what their post-processing settings were. Indeed a stronger GPU can do more post-processing than a weaker one. And if you optimize PP for the stronger GPU and use the same settings on the weaker, its predictable that the weaker GPU will choke. (which seems to be what happened in the article) A GT520 could probably work just as good (smoothness) as a GT430 as long as you lower/eliminate the PP on the GT520. Like I said, it all depends on user preference and sensitivity to video quality. I found this article from tomshardware
a while back that gives "optimal" PP settings for verious AMD and Nvidia cards at the time and found it useful. It also proves my point that you can't just use the same PP settings for every card and get the same smoothness of play.
I personally like to have a little
GPU overhead to allow for some PP and/or different encoding formats. Aka, definetly something better than a GT520 and maybe even slightly better than a 6450.
