AMD Delays ATI Radeon HD 4800 Launch to June 23
I'm afraid I have some bad news for you. Tom's Hardware has learned that ATI is going to delay the launch of its ATI Radeon HD 4850 512MB GDDR3 cards a bit to June 23th. Originally the cards were slated to come on June 18th. The GDDR5 equipped ATI Radeon HD 4870 cards will now launch at the same time as the 4850 512MB GDDR3, but it is unclear whether there'll be enough GDDR5 chips to ship the 4870 in volume right after its official launch. The report also claims that although the cards are delayed, add-in-board companies have them available right now. NVIDIA plans to launch the GeForce GTX 200 series on June 17th. In case there are no more "unexpected" delays, NVIDIA will be first this year to show its GeForce GTX 280 and GeForce GTX 260 cards, a week later AMD should follow with ATI Radeon HD 4870 GDDR5 and Radeon HD 4850 GDDR3.

and here are the reported 9900gtx specs .Higher than what I purposed. This is supposed to be leaked specs but it's not confirmed.
9900gt specs65nm process
MC 512
1GB GDDR3
240 SP
32 ROP
6+8Pin
here are some more specs none are confirmed and may be wrong. These are great for comparison to the 4870
9900gtx specs
55nm TSMC process
Single chip with "dual G92b like" cores
330-350mm2 die size
900M+ transistors
512-bit memory interface
32 ROP
192SP (24X8)
6+8 Pin PCI connector
550~600W PSU min
GDDR3 memories
10.5" long
Dual slot TM71 cooler from Coolermaster
TDP up to 240W
P651 PCB
Here you'll see the specs that have been rumored, seem to be true.
240 SPs, 1 gigabyte of 1.8ghz(im guessing it'll be higher) vram, 512-bit memory bus, tri-sli compatible - no sign of final clock speeds for the core/shaders though.
Let's hope they stick to their core:shader ratios like before! Hoping for at least affordable pricing on the gtxs - or at least a reduction in current-generation pricings!
Since the 7th post it's been mostly nVidia talk, with a bit of "last generation ati was slower than nvidia" thrown in.

the quoted 480 sounds like a much more reasonable figure, given the 3870's 320.
If it turns out to be true im sure it'll be a good thing for the budget-buying gaming community, though we've seen in the past that having more shader processors means nothing in terms of actual performance. It all depends on how they end up being clocked and on the efficiency of the way they made them work. (e.g a 128 shader gts 512 beating the 640 shader 3870x2 in a high amount of games - dont need to mention the 112 shader gt performing better than the 320 shader 3870.)
This is not true at all now with newer drivers the 3870x2 beats the 8800gts hands down. When I say newer I mean in the last month.
I think it's clear that the gtx series is going to be more powerful than ati;s offerings, however, ati will likely take the bang-for-buck or price/performance ratio crown.
My post was directed at the poor soul Tropicocity who thinks that a GTS could beat a 3870x2. 2 8800gt's in SLI can't even beat a 3870x2. I think ppl should leave benchmarks alone & try the junk themselves. The world would be a better place :D
Crysis was just fecked up to run better on the G92. Tweak the cvars a little & that problem is gone as well.
The OC'd 9800 comes close but just OC the 3870x2 & you can throw that out the window too...
:slap:
I ran 2 GTs for 2 months b4 the 3870x2 :cool:
