RV770 expected to release in May?

Looks like the RV770 (Radeon 4800) is already in production and may launch earlier than expected - in May!

Unlike the ATI that we knew before, it appears that AMD’s graphics division is running perfectly these days – and ahead of deadlines. Even though the graphics unit has posted an $8 million loss in the first quarter of this year – in an effort to improve market share rather than average selling prices - the graphics business is making progress: We hear the company has struck gold with the RV770 and will be bring the chip to market earlier than expected.

AMD’s next graphics cards are being prepared for launch: During the Q1 earnings call, president and chief operating officer Dirk Meyer stated that the company will roll out a significant number of products in May and our sources now confirmed that the introductions will include desktop and mobile (M88) graphics parts.

RV770 will launch as Radeon 4800 and will make its way into the FireStream stream processor and FireGL workstation cards. Both GDDR3 and GDDR5 memory will be supported by the chip, but ATI itself will only be offering GDDR5 cards. The Radeon 4850 version is set to come to market with an 800+ MHz core (the final clock has not been specified yet and will not be available until the final qualification is completed), while the 4870 will be the first mass-production GPU with a clock speed higher than 1 GHz. Prototype RV770 boards were clocked at about 1.05 GHz.

The graphics processor itself will integrate more texture memory units (TMUs), which is the Achilles' heel of the R6xx generation: 32 TMUs in the RV770 will challenge the 56/64 units of Nvidia’s G92/G92b.

The new graphics card generation is expected to become available to system integrators and OEMs in GDDR3/GDDR5 variants with 256/512/1024 MB buffers. 256 MB GDDR3 cards are exclusively targeted at OEMs (as well as ODMs, Sis) and are unlikely to shop up in retail. Expect to see mainly 512 MB GDDR5 cards in retail for both the 4850 and 4870. Just like the GPU, the memory clock isn't set in stone either, but we were told that the GDDR5 memory is currently running at a physical clock of 1.8 - 2.2 GHz.

With a 256-bit memory controller, we're talking about 115 to 141 GB/s of bandwidth. This number equals the memory bandwidth record set by the 2900XT 1GB GDDR4 (512-bit interface with GDDR4 at 1.1 GHz DDR).

While we expect the desktop boards to be announced soon, RV770-based FireGL boards will not be introduced until Siggraph 2008, which will open its doors on August 11.

Will be good if they actually manage to get them out on time for once.

Bring on the GPU war :D (Will be a shame since I just bought a new 8800GTX)
 
mhh sound promising but can anyone clear one thing for me rv770 for desktop and whats an

the fire gl version for laptops ? or new version of rv770 for desktops confused

RV670 was ahead of schedule as well.

Apart from R600 the last processor that was delayed was the R520.

Give Ati some credit eh? Before R600 they were beating nVIDIAs offerings since R300.

My bad I forgot about the R670, and I know how good they are ( I have a 1950XT and 1950XTX, and both wipe the floor with their Nvidia counterparts) I was confusing amd with ati:p due to phenom being late etc.
 
No, but I'd expect them to be a bit more expensive than the current 38xx range, perhaps £200-ish on the 4870 and £150 for the 4850? Just somewhat educated guesses, but I wouldn't have thought they'd be much off that?
 
i think they're supposed to be priced how the 3870s and 3850s were on launch

I got my 3850 for 115 shipped brand new right after launch and it's served me OH so well



here's to hopin :)
 
Been the usual 6 months since the 3800 series launch anyhow... so May is the right month for release :)

Shame if we dont get the 4870GX2 shortly afterwards... proberly come out 3 months afterwards :(

4870X2 :D.

I really think these 48XX are looking really promising. An RV670 at 1GHz would be pretty smoking, but the RV770 has 50% more stream processors AND a 35% core speed increase, this is looking like a proper generational bump. What's that? an 85% speed increase? Or am I getting my maths wrong?

edit: dont think its going to be 85 % increase if it will be 20% to 35% increase i would be happy

480 Stream processors, as the rumors are saying is an instant 50% increase, no?
 
Just out of curiosity. Are there any rumours on amd's new architecture for their gpus? Not this r600 based stuff.
 
well 3870x2 has 640 steam processors. maybe if then change something in core to work more efficient and better maybe then 50%. no doubt some valve games will benefit maybe 50% but not all games as i say if it will be 20~35% i'll take it
 
Okay, this is talking purely theoretical and holds quite little water, but let's take an actual look at this, these won't be standard measurements so they won't be that comparable to anything, but should give an insight:

Being the 4870 is supposed to be faster than 1GHz, I'm gonna play pessimist and say it's exactly 1GHz.

Shader power:

3870: (320x775) = 248000
4870: (480x1000) = 480000

Texturing power:

3870: (16x775) = 12400
4870: (32x1000) = 32000

Memory bandwidth (taken from gpureview.com)
3870: 72GB/s
4870: 114-140GB/s?

Raster operations:

3870: (16x775) = 12400
4870: (16x1000) = 16000

Now, while these gains are purely theoretical, they do seem rather large on the whole going by the given specifications. Therefore, I believe the 4870's will actually be pretty damn fast, probably about 60-70% faster on average. Edit: This is of course under the presumption that the 4870 is infact a linear improvement upon RV670 and hasn't been crippled by any other design flaws.

I note that the raster operations aren't improved that much, but on the R600 style architecture, it doesn't matter as much as antialiasing is performed on the shaders as opposed to the traditional ROP approach.

Then theres the clock speed boost. 50% due to more shaders and 33% more due to faster clocks? Thats a doubling in performance in terms of raw power.
