AMD HD 4850 – RV770 GPU die shot

Published on 5th June 2008 by Richard Swinburne

The new RV770 die that will frequent the HD 4850 due to arrive soon.

Never, ever leave a bit-tech person in reach of a screwdriver and an unattended next generation graphics card; otherwise this happens. People, there’s your RV770 core, the eight Qimonda memory chip layout and general red PCB goodness – enjoy and drop your comments here!

*Qimonda

Did you just write 'quinmonda'?`:D I guess it's the jet lag

Look forward to the next set of launches ... and then the wait afterwards for the prices to drop :)

Sweet. 2 weeks now until the NDA's run out on the HD4***'s and nVidia GTX280/260?

Wow! Crikey! Amazing! Look, it's... um... a little microchip.

You can see the PWMs!!

Oooh, Squigglies!
Is this just equalising trace lengths?

Sweet, I am so psyched about this upcoming release from ATI.

Hmm I thought VIA's introduced parasitic capacitance and inductance so why are there are there lots on the RAM chips? I have a pretty dense FPGA board with BGA mounted packages infront of me and I can only see three vias, seem like a veyr large number on this board. Does anyone know how many layers this is?

Technically you showed us pictures of the heat spreader. Now rip that off and show us the die!

GPUs basically all have exposed dies under the heatsinks, and R770 is no exception; that is the die, not a heat spreader.

remind me back in the days of the pentium 2......... hopefully this card will set the precedence, waiting on invidia.... in terms of price and hopefully somewhat matured drivers and reliable/efficient drivers... i'd even consider having all the systems drivers on an integrated flash bank, that can be written or read from when needed....

Let me guess, you had the flashlight pointed straight down when you took the picture of those rams. Next time, hold the light from the side, at almost board level, and let the light spill across the device sideways, on edge. You will find that doing this makes the laser etch show up much clearer than in that picture you posted., which is barely ledgable BTW.
