ATI Debuts Mobility Radeon HD 4000 Series at CES

That's a weird memory clock for the 4800 series. 888 MHz GDDR5 should equate to 114GB/s memory bandwidth.

 

OK guys and gals, i got some very good news. i got the core speed and memory for some of the 4000s series cards from one of the ATI gpu engineers at CES, here goes none thing.

4670 (680 core/800memory GDDR3, 512MB )
4650 (680 core/800memory GDDR2 or 3, 256MB)
4870 (650-680? core/700memory GDDR5, 1GB)
4850 (550 core/700memory GDDR3, 1GB)

 

Looks like ATI will take the mobile performance crown from nVidia.

 

Think you mean 4570 instead of 4750 since the specs match up. Meanwhile the other stats don't quite match up to the AMD specsheet, but I guess we'll see how accurate they are as people start getting actual laptops.

 

Awesome charts. This is starting to look really good.

I'm a bit confused with the cards used for the charts though. Initally the compared the 3470 with the 4570, and at the end they compared the 3470 with the 4370.

 

I'm dubious, but if those are the final specs, good for ATI. The 4870 will outperform even a desktop 4850.

 

Well let's wait for the actual things to come out and find out from consumer benchmarks .

Marketing benchmarks tend to look really nice, that's a given lol

 

great numbers! thanks you!

i wonder why the put the memory clock on the 4850 at 700mhz, it's kinda low. it should easily go to 800 when overclocked though.

 

Odd that the MSI GT725 would have a 4850 with 512MB then?

 

MSI's GT725 had incorrect specifications listed on their website already that had to be corrected, so it wouldn't be the first.

Then again, the card may be available in both varieties.

 

Yeah it would be nice to know the facts. Looks like Amazon's version of the MSI GT725 says 512MB VRAM. It would be nice if it was 1gig (just cause).

Im just curious how the 4850 at 512MB would perform in comparison to the 9800GTS at 1gig. Im trying to decide if I should keep my Gateway 7805u sporting the 1gig 9800GTS or return it (10 days left to decide) and pick up the ATI 4850 512MB totting GT725 off Amazon.

9800M GTS = Lower clocked (by 50/125/100 MHz on core / shaders / memory) 9600 GT
Mobility HD 4850 = between desktop HD 4830 and desktop HD 4850

As you can see, the 4830 beats the 9600 GT by 15-18% at common resolutions. Factor in that the Mobility HD 4850 is slightly faster than a 4830 and the 9800M GTS is slightly slower than a 9600 GT, I'd estimate between 18-25% faster than the 9800M GTS at a minimum.

 

again those numbers that the engineer gave me might be close to the real thing. he only gave me some numbers, since he was kinda drunk at the time we talked. if someone can test them out with their own 4850 or 70s that would be awesome. i had to buy him 3 shots just to get him to talk about it but he did pay for my cab ride to my hotel room (alone). he was really cool and i think i made a connection in my future job search and maybe work at ati/amd in the future.

 

Any speculation about 4800 series cards being released in 15.4" notebooks?

Also, it seems that a GDDR3-equipped MR HD 4870 would barely outperform the MR HD 4850 with the only real difference being core clocks. What's the point of having a GDDR3 version?

 

i dont know about that, thats up to the laptop makers.

 

Hmm... guess you're right. Anyhow, I'd love to see a 15.4" Sager with the 4850 for around $1500, not that I'd be able to afford it or anything...

Oh, and I'd totally love to test out the mobile clocks with my desktop 4870, but my frickin "reliable" Corsair power supply died on me last week (only 6 months old) and I'm waiting for a replacement. It should arrive within the next two days, however. I'll post benchmarks then.

 

you mean the 9600 gt instead of 9600m gt, right?

 

Ack yes, let me edit my post. All the M's and Mobility's and such caused a mis type.

 

Don't be suckered in by the specs, the laptop is butt ugly Stick with your gateway

 

How is ATI's track record for support of their laptop video cards?

Nvidia, while they have thier own issues, seem to be support bya very solid community of people dedicated to extract the most out of their cards, which is a big bonus for Nvidia users.

Does ATI have this and I am just not seeing it?

 

Wow $1349 seems like a great price for the MSI GT725 with P8600, 4gb DDR3, 320gb HDD, 1680x1050 res, and a fairly light 7lb weight with a 9 cell battery. The 4850 should definitely be faster than the 9800M GTS so I would go with that over the Gateway (I don't think the MSI is butt ugly, the control panel above the keyboard is just a little weird).

 

Well ATI is definitely limited with number of drivers compared to Nvidia, though I'm not sure why.

i was right on the money for the 4850 and 4870 but the others are a bit off. i just want one of those 4600's in a 14.1 form and i am set.

you know i was think about the thermal output on the 4800's and 75 watts is insane amount of heat. i was thinking of the 7950M GTX and that was 45, then the 8800M GTS at 35 and GTX at 37. the 7950M GTX was never in anything smaller then 17 that i have seem. if this beast is 75watts then i think 17 inch laptop is too small or the cooling is really buffed up. i dont think this beast will ever come out for 15 inch laptops or what until 40nm comes out.

 

ATI has support for their mobile GPU's???

Seriously though, they are notorious for *not* providing mobile drivers at all, much less updates for existing drivers.

 

9800M GTX is 75W. 9650M GT and 9600M GT is 23W. Although gigaflops isn't an absolute measurement by far, the HD 46xx (25/30W) has even more than the 9800M GTX lol. Realistically, should be above the 9700M GT (35W) easily.

 

Wow.. we might even see 4650 in 13.3" , 12-25W is good for notebook that size. I hope LG updates the P310 (with the 4670) soon.

 

680mhz core for the 4870 is pretty impressive. With some overclocking and a 2.4ghz+ Core 2 Duo, a single card setup should be reaching at least 12,500 in 3dmark06.

 

My desktop HD 4850 can't even hit 680 core with overclocking (I got a horrible overclocking chip unfortunately), so getting those clocks on a Mobility 4870 is impressive.

 

If you don't mind flashing the card (and have a more effective cooling solution), you can increase the core voltage by 0.1v. My 4870 is a stubborn overclocker as well, couldn't do past 790 MHz. Bumped the voltage up, and I've got 830 MHz, with no stability or cooling issues.

 

if the 9800m gtx is 75 then why is the 8800m gtx is only 37 watts, am i missing something here. they are the same chip in all ways. again am i missing something here.

 

Well this thread provide otherwise for power consumption of 9800M
http://forum.notebookreview.com/showthread.php?t=277667

 

Wow .1v seems like a pretty big voltage bump. What's your voltage now?

 

i tired to find a official link to nvidia but the only thing close enough i found is this,
http://www.theinquirer.net/inquirer/news/996/1027996/nvidia-g92-enter-notebook

it says the TFP is 35 watts, but i heard somewhere is 37 for the 8800m GTX and 35 for the GTS.

 

My mistake. The 8800m GTX is 37w, according to Anandtech. GTS is a few watts lower, probably 35.

 

That 75w number is just the MAX power the card itself can handle before it fries or becomes unstable. The 9800M GTX also has a power consumption maximum of 75W, but it probably doesn't use anywhere near that much power unless extremely overclocked. Same thing applies to these ATi cards.

 

1.3v. It sounds high, but my GPU never goes above 78C.

 

I thought default voltage for the 4870 was 1.26v or something. At least that was the default when I installed ATI Tray Tools.

 

Before AMD purchased ATI, they had a pretty good track record for supporting their Mobility cards, aside from mainstream OEM computers such as Dell, Gateway, HP. But that was for legal reasons, cause ATI didn't want to be sued by OEMs such as Dell if you messed up "their" GPU.
Even so, Omega Drivers were the community 3rd party drivers if you were in that boat of legal dispute. www.Driverheaven.net is where you will find Omega Drivers.

Recently (Within the last year), AMD/ATI got their act together with the drivers support, I guess they took a while to restructure when AMD purchased ATI.

 

Yea thats what I'm thinking about getting from amazon if they get it in anytime soon. I have a question abut MSI though. On another thread here someone questioned their build quality and reliability as a laptop maker, they even claimed that other products they've owned that were made by MSI made them shake their head. I have never had anything made by MSI before, so I'm wondering if anybody here has owned an MSI laptop and if it was a solid machine, and if they liked the layout of the laptop. Also even if you haven't personally owned one before are they known to be a good company for laptops?
The person that stated those facts was in a Gateway thread for their gaming laptop so he might have been bias, otherwise I would have perhaps taken his statement more seriously. That is why I'm asking here not in there.

Is it true we won't see notebooks with the HD4870 until March at the earliest? And what of the HD4850? I hope we'll see more manufacturers adopting these HD4800 cards, so far its only MSI and Asus as far as I know. I'm still leaning between purchasing a desktop replacement notebook or desktop soon but if these new graphics cards take too long to show up, I guess I'll just go for a desktop then.

 

I don't personally own an MSI, but having been on laptop forums for quite a while, I can say that MSI should be pretty reliable... probably comparable to Sager. If you're still uncertain then just check out the MSI section of this forum and read the user reviews.

 

I wonder if the 3dmark06 figures are right?
If so, this is a fastlaptop.


Oh, i found a link

http://asia.cnet.com/crave/2009/01/08/asus-w90-hits-15-000-on-3dmark06/

 

Well 15,000 isn't surprising considering that beast has TWO 4870's in it... but who exactly would want to pay thousands of dollars for such a gigantic thing? Also, I think several people have already broken 15,000 on 9800M GTX SLI machines.

 

Actually yes even with 9800GT's sli(see sig.),Johnkss has been able to pull out even better scores with GTX's and we talking about no o/c at all,these numbers(mine johnkss and few others) are about 2-3 months old so i am not amazed by these scores,the only think that counts from the way i see it is that Ati is trying for a comeback and that will only lead to better and cheaper products in the future no matter if you like nVidia or Ati ..

 

I've hit 81C load at stock clocks in a case with very good airflow, my card is just a bad model overall, mainly because of the bad reference cooler. More voltage would be more of a risk to fry my card than I'm willing to take.

 

Im in the same boat with regards to desktop or destop replacement notebook. I am curious to know how well the mobil 4850 would score in comparison to some desktop cards. The desktop I am looking at has the Nvidia 9800GTX2 1gig. Wonder how they would stack up.

 

Yeah, 15,000 in 3dmark06 is nothing unheard of, but I think the 4870 has a lot of potential for breaking the 3dmark06 record for notebooks, based on early charts and graphs. Assuming that an overclocked 4870 can match or surpass the desktop 4850, a Crossfire setup with a Quad cpu should be able to break 17,000 easily.

 

Mobile 4850 should compare favorably against the desktop 4830.

15,000 with overclocked quads is hardly as impressive as the 4870s doing it with a stock, midrange Core 2 Duo.

 

If you're talking about the 9800GX2, it's going to be much faster than a single mobile 4850, and probably a bit faster than Crossfire 4850's. But, on the other hand, that card is slightly outdated and is a huge power hog.
