Ati 4000 mobility series could come out by the end of the year :)

I don't know if these can ever be used in our CLevo's.

But since the 3870 perform like the 9800GT (a little less in single card config and a little more with dual's) the 4000 series could be really good..

I hope they get them out by the holiday season, but I think your wrong about a single 3870 mobility, I think one of them performs better than a 8800M GTS and the 9700M GTS (the 256bit) but not on par with the 9800M GT... but this is just going on 3d marks and specs I guess, the appeal to me is that it's priced very well (was), hopefully a single 4870 will be available in a 15.4" and of course a 17" by Dec, and priced generously...

ATI is strange, I don't like the shader speed on this card, but it has a ton of pipelines:

Mobility Radeon HD 3870
Codename M88
Pipelines 320 - unified
Core Speed * 660 MHz
Shader Speed * 660 MHz
Memory Speed * 850 MHz
Memory Bus Width 256 Bit
technology 55 nm

note: This probably belongs in the 'Gaming (Software and Graphics Cards)'

 

according to this http://www.guruofgaming.com/modules...topic&t=2294&postdays=0&postorder=asc&start=0 (first post and last on page 5)

the 3870 performs like the 9800gtS, but scale better (crossfire) when paired together.. Which gives it a little better numbers then 9800gt in SLI. In 3dMark06 anyway..

You're absolutely right

 

For mobility 4850 (M98) early benches go here http://www.flickr.com/photos/21969965@N05/ it seems to be almost similar to our 8800M GTX 9800M GT..
bad thing

It would be a godsend if they could get these cards out by Christmas. Highly unlikely sure, but we can dream can't we?

If not for this ridiculous defective Nvidia problem, I'd have a laptop in hand already. It feels so silly to get a mobility radeon 3650 now though with the knowledge that the 4000 series is just around the bend.

 

This will be interesting, since Nvidia hasn´t had any large competition at all in the high end segment. But with the 4870 Mobility this will definitely change.

 

You can't directly compare raw specs of ATI and nVidia CPUs since they have a different architecture. nVidia organizes their Stream Processors as independent units so if there are 128 SPs they are always fully utilized doing 128 tasks. ATI however groups the units into groups of 5. In the worst possible case, 320 of ATI's SPs will only be executing 64 tasks if poor optimization means that only 1 of the 5 SPs in each group are being utilized. This is likely pretty uncommon especially now that the drivers matured. Average utilization is probably like 2.5 units out of 5, which gives ATI 160 tasks in parallel compared to 112 SPs in the 9800M GTX. Of course, the 9800M GTX's SPs are clocked twice as high as the 3870's so the 9800M GTX's 112 SPs can complete 224 tasks in the time it takes the 3870 to complete 160 assuming 2.5 out of 5 unit execution, which is why the 9800M GTX is still faster despite having fewer SPs.

Personally I'm excited about the mainstream Mobility 4670 and 4650. nVidia's entire mainstream mobile lineup from 9500M to 9700M GT is based on a 32SP core GPU. If the Mobility 46xx is like it's desktop version which seems likely, it'll have 320SPs. The sheer number should make the Mobility 46xx better than most of nVidia's mainstream GPUs. The desktop 4670 seems to perform like a desktop 3850 so hopefully the Mobility 4670 will perform as good as the Mobility 3850.

Does anyone know where the Mobility 3850 sits in comparison to nVidia GPUs? I believe it's at least as good as the 9700M GT. If the Mobility 4670 can get somewhere between around the 9700M GT or 9700M GTS with the Mobility 4650 slotting in at say a 9600M GT or 9650M GS, I think ATI will definitely be able to retake mobile GPU market share.

 

I think the 3870 is about equal to an 8800m GTX or 9800m GT, so im assuming the 3850 should be at the level of the 8800mGTS/9800m GTS.

 

Any ATI Gurus willing to share their knowledge about the differences between the 3000's and the new 4000's? Or is it still to early to know the exact differences.

 

Just read a review of the desktop versions.

http://www.anandtech.com/video/showdoc.aspx?i=3341

The major differences is more of almost everything. Like the 48xx has 800 SPs compared to 320 SPs in the 38xx. The 46xx has 320 SPs compared to 120 in the 36xx. The major improvement is the number of TMUs at 40 in the 48xx compared to 16 in the 38xx. ATI has always been weak at texturing all the way back to the X1900 which also only had 16 TMUs when the nVidia 7900 series had 24. It's nice to see after 3 generations ATI finally decided to address this issue.

Besides sheer numbers there have also been some architectural tweaks too. The most significant is that the 4000 series now has dedicated hardware units for AA. In the 2000 and 3000 series, ATI thought they had enough SPs that they can do most of the AA work in software, which wasn't the case. Now ATI has added back dedicated AA hardware which should take load off the SP and speed things up. The software AA mode is still available and show also be faster simply due to the 2.5 times more SPs in the 4870 compared to the 3870.

ATI also went smart by keeping the same 256-bit memory interface but using very high clock GDDR5 in the 4870. In comparison, nVidia went with a 512-bit memory interface in the GT200s with slower GDDR3. ATI's strategy is smarter since a 512-bit memory interface on a chip takes a lot of transistors, increases power, and heat and also makes layout of the graphics board very complex. It's just easier for everyone to stick with a 256-bit memory interface with higher clocked memory.

The mainstream 46xx series is also following a similar strategy where a 128-bit memory interface is kept unlike the 256-bit in the desktop 9600GT. Current lower-end mainstream mobile GPUs typically get saddled with commodity DDR2, which is cheap but comparatively slow compared to GDDR3. Like a laptop with a 8600M GT with 256MB of GDDR3 is faster than one with the same 8600M GT with 512MB of DDR2. The 46xx series now has support for commodity DDR3, which should replace DDR2 and bring higher clock speeds for mainstream users. GDDR3 will still be faster than DDR3, but the gap is narrower.

 

actually the desktop hd 4670 is like a crippled hd 3850. it's got 320 unified shaders but only 128bit memory bus, versus the 256bit memory bus of the hd 3850. it's still a great card though, since it's priced like a 9500 gt desktop (that's UK pricing=BS).

anyhow, ati might persuade me to stay in the laptop gaming for a bit longer. performance/price is what I seek.

 

itcommander, so ati has started using ddr3 for graphics memory? I think this is the first time that ddr3 is used in that field, right?

 

Yes that's why I mentioned it. As DDR3 prices drop and we should see GDDR3 class performance with DDR2 prices. GDDR3 will probably still offer slightly higher clock rates and slightly higher performance at the same clocks due to some optimizations specifically for GPUs, but it should be negligible to DDR3. DDR3 is replacing DDR2 and GDDR5 will replace GDDR3.

The 4670 has less memory bandwidth than the 3850 which is a disadvantage for higher resolutions. But the 4670 probably has more processing power seeing that it has double the TMUs, more and larger caches for the SPs, and dedicated AA hardware.

 

hmm, so the hd 4670 is using the new core, I thought it was just the same r670. cool.

 

The desktop 4850 is a beastly card! If the mobile version is anywhere near it then it would be awesome!

Those 4850's better have a sweet AMD platform with a smoking AMD CPU to make for probably "seamless integration". One would think this, for everything would be AMD.

 

im really interested in knowing if that 4350/4550 budget card will go into the current portable notebooks of course they were talking about the desktop version there but still its shows that it is very possible if these thing can give two times the performance of a 3470 then im sold

 

I'm sorry to talk about this so much, I'm waiting for more news of the ATI XGP from AMD!

 

What do you mean by a "seamless integration"? Would an ATi + Intel processor combo not be as effective?

I'm sorry for my ignorance in this feild.. but does anybody have a guess to how long will it take to see some barebones surface with the Mobility Radeon HD 4000 Series? In hopes of not asking for too much already.. what about something with an Intel processor as well?

Also, judging from how similar the Radeon Mobility HD 3650 is to the desktop card.. perhaps the 4650 will be noticeably faster than the Geforce 9600m GT. I like to see that

 

Theres no way that can be right, A mobility 3850 gives the same performance as a 9700GT/GTS and i am 100% sure the 4650 will be better if even slightly
