ATI Radeon HD 4800 Series Video Cards Specs Leaked
Thanks to TG Daily we can now talk about the very soon to be released ATI HD 4800 series of graphics cards with more details. One week ahead of its presumable release date, general specifications of the new cards have been revealed. All Radeon 4800 graphics will use the 55nm TSMC produced RV770 GPU, that include over 800 million transistors, 480 stream processors or shader units (96+384), 32 texture units, 16 ROPs, a 256-bit memory controller (512-bit for the Radeon 4870 X2) and native GDDR3/4/5 support as reported before. At first, AMD's graphics division will launch three new cards - Radeon HD 4850, 4870 and 4870 X2:

im gonna need something that can play all games at 1920x1200 smoothly with all settings turned up since im getting a new gateway 24" monitor.
Aimed at no one in particular:
ANYTHING YOU SAY ABOUT NV OR ATI SUCKING CAN BE APPLIED EQUALLY TO THE OTHER ONE. PLEASE STOP THIS REPETITIVE FANBOI CRAP.
However they said "match" we want to see the HD 4800 series MOW DOWN the G92s...
-tkpenalty sighs- although its rather early to judge, I would be surprised if these manage to trample the G92 series. AMD for the R6xx GPUs have obviously had a deficit in the TMUs/ROPs, I find it VERY hard to believe how they oversaw that. Their GPUs have the shader power... but not the texturing power to compensate.
for my nv card i was using 174.74 and it blue screened occasionally, i downgraded to 169.44 for more stability, im waiting for a new WHQL driver soon. even though WHQL means a bunch of M$ people played with it for a while and said "yup, seems ok to me"
Edit: Actually it is closer to triple the price.
I'm hoping the HD4870 is better than the 9800GTX, or at least as good which shouldn't be a problem judging from the specs. I would love to see some decent competition at that price point again. Which I hope will drive prices down about $50.
I am disappointed that it seems the 4870 won't have a 1Ghz core speed though.
I pointed out that there was a claim that the HD4870 would be the worlds first mass produced GPU clocked at 1GHz and asked what happened to that.
He then said it went away just like 100% efficient SLI. Which implies that somewhere it was claimed that SLI would be 100% efficient.
I then asked him to show me where that was claimed, which he was unable to do because it was never claimed. I never said it wasn't possible, I said it wasn't possible for him to produce an article with that claim in it because no article exists.
I think the same thing is true in the GPU market. There used to be some "stability" were the number increases of the cards were in 50s or 100s. Now we have a 1000 change from one Q to the next.
Too much I say. I'm not confused. But I DO HAVE TO SPEND TOO MUCH TIME researching ans staying on top of this product confusion.
Or are the GPU manufacturers doing this DELIBERATELY to get FREE advertising on the various websites and magazines? If they went from 3870 to 3875, perhaps they wouldnt get so much free advertising as when they go from 3870 to 4870 and the "rumours", and the "no tech spec yet", and "tech spec tomorrow", etc. fills the web with all sorts of "brand awareness" copy+paste.
IMO this just goes to show that PR and ad agencies get paid on the WRONG METRIC. They get "paid" for how often information is linked to between websites, and how far up the search engines the information appears.
This only ENCOURAGES smoke and mirrors and tech-site discussion to create page-count to hit the search engines.
AAAARRRGGGHHHH cynic.
Benchmark HD 4870 on beta drivers vs. HD 3870, HD 3870 Crossfire on Cat 8.4 and 8800GT here: HD.3870.3Dmark06=12,590 vs. HD.4870.3Dmark06benchmark.leak.html=21,223 :D. It's definitely MUCH faster than you were expecting :roll:
