The NEXT LAST R600 Rumours & Speculation Thread

it's a nice thing that you're happy, do you want to make us happy as well?

 

Any 2900XL specs/clockspeeds out yet? Fuad talks a little about that card today.

I hope they haven't crippled the GPU and just lowered the clocks. A $349 card maybe? Very interesting days to come.

 

And that's to say the very least.

 

the teasing continue!

X2900 review. Well, not really, but the menu "works".

Page 19: UnReal Overclocking! Probably playing around with voltmods and uber cooling.

 

I take your and raise it to

 

haha

18. overclocking

19. UnReal overclocking!!

 

Thanks for the clear up, but what about this cooler?

 

R600 happens to be late, without XTX and insanely overclockable at the same time. AMD sure knows how to butter up enthusiasts .

 

DX8 shaders just use FP math.

 

I think you're wrong here...

G80 has to execute all work related to each pixel on the same SIMD unit as the cache is inside it, so it needs a lot of data manipulations in order to get it to a good efficiency.

If you exit a SIMD unit with a result to use it inside another one, it will add even more latency and chance is you're going to have a bottleneck here if you do this too often.

 

If you read (good) heatsink reviews closely, you will notice that heatsinks benefit noticeably from a higher airspeed over their fins. This is particulary true of the closely spaced fins of heatsinks that are supposed to be fan driven. I think heavier fans will push the max up higher. Then some of the board makers will replace the reference heatsink with one of their own design. The XTX fan has a max output of 24 watt, thats humongous! I held a 120x38 propeller fan with similar power in my hand once, it was like an outboard engine propeller!

 

My hates both of you!

 

This should be from the same documents as the previous pic

 

102-B007 is DragonsHead2 aka 2900 XTX 1GB DDR4 .. the delayed one..
B006 was CatsEye the 10-15% slower clocked than XTX with 512MB .
B001 was Dragonshead, or the OEM XTX
So XT could launch at 750 and XTX at 825

I do however see no mention of UFO (XL, B002) in there.

 

There is no data exchange between SIMD units needed during a PS execution on the G80 and vectorized shaders are trivially serialized by a compiler. If you're thinking about swizzling, the G80 needs no swizzling, swizzling is done at compile time.

 

Brent Justice over at [H] makes me nervous again.

It would be nice to fall asleep tonight and wake up on May 14th. This waiting is killing me.

 

Buy a 8800gtx and than you can sleep

 

Or if you have a wife or girlfriend, you know what to do to fall a sleep.
