TMUs help AF. ;)Quote:

Not that it matters much though- 8x Box AA or 2x Narrow/Wide Tent AA are extremely good, and Edge Detect 4x can match 16xQ or even more.
Currently you need a better raw speed for those modes, and the 4ks are gonna bring that for a start.
Not really.Quote:

Faster/more TMUs can accelerate it in some cases ( lets say that the cards TF was bottlenecked by the TMUs for example ).

Looks like that early photo of the PCB with the small silver square was not fake after all.Quote:

Beautiful card imo. Hopefully these are gonna perform at least like 8800GTS 512MB or slightly better I'd hope.Quote:

The 4870 is going to look something like this (old news. I know =)Quote:

Just found an update here:
http://www.tomshardware.com/news/amd...deon,5514.html
The shipping to retailers has started according to toms :shocked: :up:
"We were told that AMD/ATI will decide on final pricing during the Computex tradeshow (which is scheduled to open on Monday) in order to have all the puzzle pieces for a June 18 in place. It certainly does not look like a paper launch at this time and the June 18 is an as-of-now date, since the company could revise is launch schedule to avoid a launch right on the heels of Nvidia’s new high-end parts"
yep

AMD Starts Shipping ATI Radeon HD 4850 Video Cards
The ATI Radeon HD 4850 cards are reportedly already shipping to OEM partners and retailers. According to TG Daily everything is going as planned and AMD/ATI is aiming for a sizable launch of the new product generation, with Radeon 4850 512MB boards leading the charge. The final prices for all Radeon HD 4 series cards will be officially declared during the Computex 2008 tradeshow which will open doors on Monday. Higher-end Radeon 4870 cards with 512MB of onboard GDDR5 memory are expected to ship in volume sometime this summer, with flagship Radeon HD 4870 X2 to follow soon after that.

ugh 512MB ddr5 on the 4870
thought we were gonna get 1GB cards? :(
Yes - they are shipping later, GDDR5 takes its sweet time compared to GDDR3 which is already in place.Quote:
