ATI Radeon HD 4000 series coming in June?

Link 1
Link 2
Link 3

4400 for small laptops, 4600 for mainly 14-16", 4800 for high end 15 and up. Why would the low end 4400's use GDDR2 when some Nvidia 8400GS's already use GDDR3?

 

cool, ATI 4800 and then with Monetiva. June/July is going to be the best time to buy a new PC. Unfortunately, i cant wait that long or pobably afford it.

 

These are for desktop. ATI name for notebook graphics is Radeon Mobility.

In any event, expect Mobile versions of these perhaps 3-6 months after desktop release.

The Radeon Mobility 3870 is expected to be release in March April.

 

wow they are just moving along arnt they...and GDDR5? wow!

 

cool anyone have any idea about price range?

 

Looks fake to me. Unless they just took the 3 series and doubled everything. Doesn't make much sense to release this before HD3670s have fully hit the market.

 

2 GB GDDR5 memory??!?

 

I cant wait for GDDR9

 

Neither can I. Therefore, I won't.

 

Price.
Even pennies differences add up for AIBs, so they go as cheap as possible, both series currently have many DDRII versions in the low-end;

If you look at your own links though the 4470 also has GDDR3 listed as well so it at least supports both of those memory types so it's not limited to DDRII.

 

The 3000 series has only been out 5 minutes? Either this is wrong or ATi are going all out to reclaim the graphics card market.

 

Going out to reclaim the graphic market I'll wager. At least on paper. Plus ATI beat Nvidia with DX10.1 compliant hardware and 55nm die. They're on a tear.

 

Sounds a bit suspicious. 2GB RAM is extreme overkill. Or to put it another way, how would you like to have a cap of 1.6GB RAM on your 32-bit system, rather than the current ~3.3GB?
If the OS has to memory-map 2GB for the GPU alone, you won't even be able to see 2GB system RAM unless you run 64-bit.

And of course, RAM is expensive, and there's just no benefit to using that much. I doubt it's true.

However, AMD might well be close to releasing the 4000 series. I just doubt the specific specs given here.

 

Rumours anyone ? HD 3870 isn`t even out and the 2 terraflop mark is going to be passed by another card? come on...

 

That seems a little suspicious.

 

They are skipping GDDR4 and going to 5...I call BS. Hell GDDR3 is running 2ghz EASY. I haven't seen a 8800GT not hit 2ghz.

 

I don't think this is BS. The HD3xxx series was only really a die shrinkage and tweaking of the 2xxx series, not really a whole new architecture/generation. The HD4xxx series is the real next generation after the 2xxx series. I'm just excited that the mid-range cards, HD4650 (based on the RV740 core) now has a 256-bit bus! I guess that's in response to the soon to be released 9600GT also having a 256-bit bus.

Good days are coming for the mid-range market.

 

Maybe I should defer the upgrade.... I was planning on a 3670!

 

ATI/AMD have alot of ground to make, its good they are working hard(if this is true) to catch up and keep things competitive, the 3800 series are great cards at good prices, and if they can continue this trend they will do alot better.

 

Yes this has got to be in response to the 256-bit 9600GT if this is true. If they have it out by summer i will buy whichever one is better. But I don't get it, are they just going to forget about the HD3670 for laptops?

 

well as of now they are a series behind in the mobile world, maybe it will just stay that way.

 

Why the skecpticism based on GDDR5, and who are you calling BS on?

AMD isn't skipping GDDR4 they use it in their high and mid-range, for nV skipping GDDR4 and going straight to 5 without the hassles seen in 2007 with the highspeed stuff would be a nice bonus; although you need to be able to at least support GDDR4 to support GDDR5 since the spec was made to be very compatible with existing GDDR4 marchitecture without much rework [don't nee more memory design delays like the R520].

Using your DDR numbers there, GDDR5 at pre-launch is already hitting above 3.2ghz at 1.5v instead of the 1.8v of the GDDR3 & GDDR4 (low speed GDDR4 is 1.5v), so that's 3 times as fast at reported 20% power saving.

All this on a 1Gb chip with a 64bit/32bit interface means far fewer chips to do the same thing we do now with GDDR3 even clock for clock without the speed boost. And 2Gb modules are already spec'ed and expected by the midle of this year. Think about it 1GB of memory on 4 chips, sounds perfect for laptops.

Faster, more efficient, cooler and cheaper, sounds good to me, don't see why you would think it's BS.

Also remember in this desktop space which are the focus of the links above, AMD appears to be moving back to 256/512bit external/internal memory interface, which saves them transistors, wires traces and PCB complextiy (all of which translate to cost savings) while reducing wire cross talk because they aren't as tightly packed together and don't need to be as thin to connect to an ever shrinking die/package. Supposedly the reason for no GDDR4 on the G80 is issues with singnal tolerances. Unless they improve their design on the G100/T200 that 512bit memory interface may be forced to keep riding that GDDR3 which will need to clock faster to compensate.

Personally GDDR5 is a let down (it's already over 4 months late) I was hoping they would've already been on to XDR by now since nVidia and ATi started licensing agreements years ago in 2004-2005.
While GDDR5 is nice, top XDR is currently running at almost twice the throughput and 3 times the speed on 512Mb chips, biggest problem is price/cost since each of those 64MB chip costs about $25 each, even in large quantity.

 

These new 4000 series are based on the R700 architecture while the 3000 series is based on R600. ATI says it update mobile architecuture every 12 months, so I believe we will see the 4000 series for notebooks after the launch of Montevina.

 

If it's every 12 months, then the top R700 (4870) will come out March-May of 2009. The top R600 (3870) hasn't been released yet for mobile. It's rumored/expected in March-May of this year.

 

I think he meant the R600 series itself which would've launched with the HD2K models. So R600->R700 models would mean late summer if it were a strict 12 months.

Personally I don't go on the strict rules because they keep getting broken, especially in the mobile segment. I usually just 'hope' that a few months after a desktop part appears they may decide to plop some mobilized version in a laptop, and that it's something close to the same power.
I won't even guess with the HD4K series since it's more modular design could mean anything, including quicker time due to smaller more eficient part or longer time due die-package requirements.

My edjumakaturd guess would be desktop by mid-July, mobile by end of August. Then add any delay to desktop time as delay to laptop time.

 

Yeah, I'm figuring about the same. Low to mid tier 4xxx Mobility series by late summer with the high/top tier late fall to early winter. But the first lappies with the top card being available by Christmas to Jan '09.

Manufacturers may debate a decision to go with AMD's Puma to get the most out of these cards instead of Montevina. Or wait until Intel's Nepthalim debuts and design for that.

 

It's so much on the horizone with notebooks. They keep releasing new stuff almost everyday. But they forget to put out any actual computers with the stuff in on the way!
