Eye-balling GM204 to the size of memory module and GP104 to the memory module, it look like GP104 is about the same, or even larger.
I don't have anything on this PC to do measurements.
You can just MS paint.
It's not that hard, and eye balling, GM204 is ~20% larger.
as rough as it is, comparison based on pixels between die and pcb resulted in 27% for GM204 and 25% of area.
Which means GP104 is 92% of GM204.
92% x 398= around 365mm sq
*if the substrate pcb is the same size.
Btw, if true, these prices are ridiculous. lol
They just keep on creeping up higher and higher for mid-range.
If $500 midrange chips becomes the norm I'm done with PC gaming once my 970 starts sucking and will buy a Playstation next generation.
Easier to compare to GDDR5 since that's a known quantity.
IIRC, GDDR5 modules are 14mm x 12mm.
Eye balling, it looks like GP104 is 18mm x 16mm approximate, ~288mm2.
If it's 256bit gddr5/x than 8gb vram is 100% sure.Do we know yet how much RAM the 1080 will have?
I see so much mention everywhere, including wccf etc., referring to 970 and 980 replacements and sometimes a 1080ti is mentioned but almost as an afterthought. Any bets on the release being 1080Ti, 1080, 1070, with the 1070 being slightly faster than a 980, a 1080 being slightly faster than a 980Ti, and a 1080Ti being significantly faster, say 40-50%?
I hope not. Is there any reason to trust that chiphell source?
Doesn't tell you much, does it :hmm:Here is cross-section of both GP104 and GM204 based on this img (horizontal and vertical):
I get ~321mm²...
Edit - It looks like the shots are lined up with the white lines around the outside of each die.
The entry gamer today already pays ~300$.
Btw they also confirmed DDR5 for 1070 and DDR5X for 1080.
Shot are in line with cooler mounting holes, which can change from generation to generation. Explains the difference in white lines and why it doesn't match.
It is pretty big chip ^^
Apropos the white lines, you can't necessarily trust those, since the GP104 picture has been clearly photoshopped. The die picture has been copypasted into another picture, which is quite obvious from the fact that the die looks perfectly clear, whereas the underlying PCB of the card is a mess of compression artifacts.
Basically videocardz took this image and unskewed it so that they got this image, they then took the unskewed image and copypasted into this image. There's quite a lot of room for error in this process.
For what it's worth videocardz estimated the die size at 332.9 mm2.

1070 looks like crap.Will be interesting to see how close to the Geforce GTX 980 Ti the GDDR5-based GP104 will be perf-wise, considering GM200's ~31% bandwidth advantage.
