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:
  • ATI Radeon HD 4850 - 650MHz/850MHz/1140MHz core/shader/memory clock speeds, 20.8 GTexel/s (32 TMU x 0.65 GHz) fill-rate, available in 256MB/512MB of GDDR3 memory or 512MB of GDDR5 memory clocked at 1.73GHz
  • ATI Radeon HD 4870 - 850MHz/1050MHz/1940MHz core/shader/memory clock speeds, 27.2 GTexel/s (32 TMU x 0.85 GHz) fill-rate, available in 1GB GDDR5 version only
  • ATI Radeon HD 4870 X2 - unknown core/shader clock speeds, available with 2048MB of GDDR5 memory clocked at 1730MHz
The 4850 256MB GDDR3 version will arrive as the successor of the 3850 256MB with a price in the sub-$200 range. The 4850 512MB GDDR3 should retail for $229, while the 4850 512MB GDDR5 will set you back about $249-269. The 1GB GDDR5 powered 4870 will retail between $329-349. The flagship Radeon HD 4870 X2 will ship later this year for $499.

im torn between the 4870 and 9900gtx, im just gonna have to see benchmarks... :banghead:

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.

Nice specs and price ranges, but ATi really should hire some folk that actually CAN program drivers... when this happens, their lower prices will beat the hell out of nVidia or at least create some real competition.

i dont think their drivers are the problem also nvidia has traditionally been the one with the driver problems

both have. repeatedly.

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.

i can honestly say the quality of ati drivers have fallen.

mandeloreLMFAO , you're saying this about ATI???

try appling that rant to Nvidia, then you will be onto something
Actually, he is just saying it in general. I don't say any mention of specific companys at all in his rant. For all you know he is talking about graphics companies in general. Of course an ATi fanboy would instantly take the defensive for ATi, and the fact that you seem to imply that ATi is innocent of this and nVidia isn't just adds more argument to your fanboyism. The fact is both do it.

Fillrate... meh all marketing BS. The drivers are the reason why the GPUs dont perform as the specs say they should. Anyway, analysing the fillrate of the HD3850s... it seems pretty obvious why the GPUs had less performance...

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.

when i had my x800 i always used omega drivers, they seemed better.

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"

Looks good, should be 1.5-1.8x as fast, should make the 38xx series rock bottom prices too...

magibegThat seems extremely conservative. 320 stream processors to 480 is like a 50% increase in that alone. Then theres the 1050mhz shader speed to the 775. The faster memory should help a little, the fact its 1GB. I would say a clear 50%+ increase if i had to guess.
I don't want to set myself up for disappointment, lol. So I'm fibbing to myself. I'm really hoping its 50% faster. That would be fantastic. :rockout:

Disappointment is become sort of a phenomenon off late. 8800 GTX -> 9800 GTX, talk about disappointment.

I don't see why everyone was so disappointed with the 9800GTX. It is exactly what nVidia said it was going to be. It isn't like they hyped the specs up and then released something that wasn't even close. I still don't understand why everyone heard "G92 based card with higher clocks" and then expected some beast that would blow away everything currently out. You knew what it was from the day it was announced, you can't be disappointed when a card comes out exactly as it was presented.

its faster than the 8800GTX, uses less power and runs colder. it also has better decoding for HD media (that was missing from the GTX and ultra, while the 8500/8600 always had it)

True, for about double the price, but a single HD3870 does not. A 9600GT is faster than a HD3870.

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.

newtekie1It is impossible because the claim was never made.
I love your logic! If it's not claimed, then it's not possible! :rockout: :rolleyes:

I am disappointed that it seems the 4870 won't have a 1Ghz core speed though.

Well atleast these specs seem to be more believable then the junk we saw a few weeks ago. I'm still aiming for the x2. Its stacking up to be sick monster. I wonder when we'll see a game that can use all that power :D

No, you seem to not be able to follow the conversation.

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.

batmangI'm gonna guess 15% at default clocks.
lol at you, plucking random figures from the air. 320 SPs versus 480 SPs, what's the increase there? 50%? Correct. Even the clock increase to 850 on the core is 10%, never mind the independent shader clock. Use common sense and you wouldn't have to pluck random figures out of the air.

*Cough* I was joking :rolleyes: that's why I didn't quote your whole post :D

The renumbering of GPUs is causing market confusion. (Perhaps a few TPU experts canbe excepted from the generalisation). Imagine if every year there was a different car model number. The amount of advertising, reposition of brand and model, and confusion in the marketplace as to which model to buy etc.

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:
