Will do. Guy was responsive with email, supposed to email tracking info tomorrow, cards to arrive Tuesday. I'll post pics first and hopefully some benchies later. Just downloaded Catalyst 8.6 betas..

They will probably come with drivers on the CD's which will be more suited than the 8.6betas that are floating around. Let us know how it works out- I'd like to see how it compares to my Crossfire 3850's.

well, consider that the 4870 is a 4850 only with GDDR5 ram instead of GDDR3... and the delays in aquiring GDDR5... I expect price hikes on the 4870...

if the 4870x2 can really share the ram, then maybe we wouldn't be seeing any 4870s for a while due to ram amounts, and just 4870x2 GDDR5

if 4870 is available at the rumored $299 then it will be VERY good. gddr5 on that card is going to make a world of difference at high resolutions imho. the only question is when will it be available? of course, we could ask the same of 280 and 260 since nvidia doesn't seem to be exactly flooding the market with them...if 4850 is the amazon then 280/260 is my sprinkler.

So put water on it. Still makes up for $300.

New gpu-z

 

[unr3al]

40 TMUs would be nice, and looking at the benchmarks, I could easily believe it lol

 

[dug777]

Am I the only one who finds this 'everything in one thread' completely useless for actually finding anything out about the product and where it's at?

The first page is out of date, and the last is discussing specifics.

Not exactly helpful

I imagine ViRge is going to create a new 48xx thread come NDA lift like he just did for nV lauch. A new thread should help..

Yep, we'll roll out a new thread for the reviews. For the time being it is a bit of a wild thread I do admit, but it's easy enough to find things with searching. Besides, everything is still a rumor at this point.

You could also talk to the topic creator and have him inject some initial info in to the first post.

 

[zod96]

Now I'm really freaked. I read the reviews on reseller ratings on Buy.com and yeah lifetime rating of 2 and most reviews said "I ordered something that said in stock" and well you know the rest :-( I'll wait till weds. If they haven't shipped by then I'll cancel...

 

[biostud]

Could the NDA date be posted in the first post?

"AMD says its 4850 device at about 110 W and $199 will deliver about 75 percent of the performance of Nvidia's high-end GTX280 which costs $649 and dissipates 236W. Two of the AMD [4850] parts on a board will hit graphics benchmarks about 30 percent higher than the Nvidia device, the AMD spokesman added.

A 4870 version of the product sporting slightly higher performance will cost $299. Both AMD chips are made in a 55nm process, compared to 65nm for the Nvidia chips, and measure about 16x16mm compared to about 24x24mm for the Nvidia part. The approach gives Nvidia bragging rights for the single most powerful graphics processor, an edge that plays well to the gaming and technical communities who use the parts.

On paper the AMD approach looks good," said Jon Peddie, principal of graphics market watcher Jon Peddie Research (Tiburon, Calif.). "If it works, it will be a significant shift in how GPUs are made, but we won't know until later this year" when customers can test the new parts, he said."

For those who are having trouble getting information from this thread, I'll try and condense it all here. Please note that AA performance has been "fixed" with the Rx7xx architecture. AA is now done properly on the render back-end (just like Rx5xx) instead of on the shaders (Rx6xx).

Radeon HD 4850 (AKA "RV770Pro")
-DX10.1 / SM4.1 & PCIe 2.0
-160 5-way VLIW shader units (800 SPs); 16 ROPs, 32 TMUs
-625 MHz Core clock
-256-bit bus (512-bit internal)
-512MB of 1000 MHz GDDR3 (2.0 GHz effective); 64 GB/s bandwidth
-1 x 6-pin PEG connectors, single-slot, 9.5"
-1.0 TFLOPs
-MSRP: 199-219 USD; Available June 25th.
*=/> 9800 GTX*

Radeon HD 4870 (AKA "RV770XT")
-DX10.1 / SM4.1 & PCIe 2.0
-160 5-way VLIW shader units (800 SPs); 16 ROPs, 32 TMUs
-750-850 MHz Core clock (750 most likely)
-256-bit bus (512-bit internal)
-512MB of 19xx MHz GDDR5 (3.8 GHz effective); 12x.x GB/s bandwidth
-2 x 6-pin PEG connectors, dual-slot, 9.5"
-1.2 TFLOPs
-MSRP: 299-329 USD; Available June 25th.
*=/< GTX 260*

I haven't seen any info on R700 in my limited searching in this thread, but here is my most educated and FUD-less guess from what I have read.

Radeon HD 4870 X2 (AKA "R700")
-DX10.1 / SM4.1 & PCIe 2.0 (TRUE PCIe 2.0 with an AMD dev'd PCIe 2.0 bridge chip)
-2 x 160 5-way VLIW shader units (2 x 800 SPs); 2 x 16 ROPs, 2 x 32 TMUs
-750-850 MHz Core clock
-512-bit SHARED bus (1024-internal)
-1024MB of SHARED ?? GHz GDDR5 (?? GHz effective) - Most likely similar to the 4870.
-1 x 6-pin PEG connector + 1 x 8-pin PEG connector, dual-slot, 10.5"
-2.4+ TFLOPs (HD 4870 X2 CrossFireX = 5.0 TFLOP system! *drools*)
-MSRP: 449+ USD; Available late August 2008.
*> GTX 280*

I hope that sums it up for anyone looking for it. If anyone wishes, please correct me on this info if you have good reason to believe it is wrong. I will add die sizes/transistor counts once I get more solid info (have read lots of conflicting articles recently.)

Seems ambitious, but unverified CF benchies I've seen put 4850 CF over GTX 280. I think they used 8.5 drivers. 8.6 is supposed to release with hardware launch.

I'll know tomorrow, two 4850's on the way. I'll try 8.5 and 8.6 betas.

Test system:
Visa 64 SP1
Asus Rampage Formula x48
8GB Muskin Redline 1066 5-5-5-18,
E8400 @ 3.8

I've sold most of my games so I only have these to benchmark:
3DMark06
3DMark Vantage
Assassin's Creed
Mass Effect
Oblivion

Looking good man, can't wait for results. Do you have a 9800GTX you can run in that same system?

 

[deerhunter716]

Gotta admit been a Nvidia fanboy; BUT the 4870 might just be my new card as I think it may put a hurting on the 260 and a LOT cheaper.

 

[zod96]

I have one ordered from Buy.com that is supposed to ship today via 2 day air we'll see I'll post some thoughts if it comes...

 

[SniperDaws]

sorry i should learn to read properly instead of getting carried away.

 

[Piano Man]

I'm just glad that it looks like AMD/ATI might be putting up a fight this round with nVidia because I think we can all agree that video card prices have gotten a little high compared to other PC components. This should hopefully keep nVidia in check when it comes to pricing.

 

[deerhunter716]

Yep - been huge Nvidia guy like I said; but I am really looking forward to the 4870 with that price point. We all could be in for a pleasant surprise.

omg is ATI's card going to be slower than the GTX280 ?

FFS this is bollox, Nvidia's card isnt much faster than the 8800GTX not to mention its power needs and massive heat it throws out. ATI could of stolen the crown.

Are you joking me? Take a look at this page and tell me that 50-70% clock-for-clock "isn't much faster".

Yeah i just looked at my usual buying website www.scan.co.uk and they have 3 diffrent brands of the 280GTX selling for £433 and the rest are dearer. ill never pay that for Graphics card.

Sorry Warren you're right, i didnt read the review properly and i also didnt realise Anand had done a review, i was reading an early one, im going to read anandtechs now

And that's with the GPU underclocked to 575! Some of these bad boys are already getting to 700+ overclocks.

No, I sold it.
