ATI 5000HD details leak -UPDATED

Well, the ATI HD 5770 aint a bad card, since its close or better than the ATI HD 4870.

 

Exactly why I dont like this. It is not an upgrade in general, just a "renaming a la NVIDIA" (3D performance-wise), the difference will be in consumption, DX11, and heat output.

 

how close is the mobile 4870 to the desktop 4870?

 

Check this with detail. It is worrying.

The mobile HD4870 is basically an overclocked mobile HD4850 because AFAIK, there are no mobile HD4850s using GDDR5(which was one of the biggest differences between the HD4850 and HD4870). The mobile HD4870 was therefore more akin to a desktop HD4850 than an HD4870.

I'm also a bit disappointed in the HD5xxx series at least in the high end segment. In the midrange segment, the extra efficiency is going to be useful.

 

the 4870 in laptops are EQUAL to the desktop 4850 because there is no DDR5 on them

 

Arent the clocks higher on the 4870??

 

An extra 50Mhz over the Mob. 4850 cards.

 

Ok, I am getting lost.
Let us leave the Desktop parts aside.
The 4870HD Mobility, what are the differences with the Mobility 4850HD? Only clocks>?

 

The Mob. 4870 (or as I call it the Mob. 4850+) has a 50Mhz stock clock advantage over the Mob. 4850.

The Mob. 5870 gains 150Mhz on the Mob. 4850+.

 

It is barely nothing, but the 5870 hasnt got double the shaders now? (even though it is based on the 5770)

 

The desktop 5870 has double the shaders at 1600. The Mobility 5870 has the same 800.

 

If you're wondering how the 128bit bus with GDDR3 will cripple the Mobility HD58xx, than here's your answer (pretty much).

Needless to say, this is not what we were waiting for, even the HD4850 scored better - 5413 points GPU Score in Vantage. I know the 3DMarks does not represent the overall performance of the GPU but gotta say, this doesn't look nice.

 

I just ran Vantage at stock speeds, and scored 4362.

 

GT725 with HD4850 and P9600 I tested earlier scored:

Stock
P5248
CPU: 4810
GPU: 5413

After OC
P5771
CPU: 5702
GPU: 5714
So the mobility HD5850 with GDDR3 scores are not mindblowing.

 

... on your GTX 260m ?

Mine is 53-4xx

 

I found an older run in my Photobucket, and it shows 4522. That's the highest I will get without overclocking.

Your memory is at 950MHz, so yeah you'll get higher.

 

:/ huge difference ...

Stupid mxm 2.1

 

cry ........

 

In the 5850 in the review above the memory seems underclocked compared to ATI specs for the GDDR3 version.

 

Yeah, but these 3GB/s won't make a huge difference.

 

Of course not, but talk about adding insult to injury... kill the bandwidth by using GDDR3, and then kill it further by underclocking

 

I will ascend 3.0b in March, once we see what Nvidia brings with their new GTX.

I need no less than Mobility 5870 power in a 15.6" machine.

 

Nvidia already have and it's a complete re-badge.

 

To my knowledge, Nvidia hasn't revealed anything about the GTX 300M.

 

Rebadge ? At least most of them are not g92 this time around

they are desktop g215 cores

 

No, they're not. You are talking about GTS 300M, not GTX 300M.

 

Nvidia GPUs:

16 Cores = G218
48 Cores = G216
72 or 96 Cores = G215

>96 Cores = ?????? (right now they're G92)

 

As far as I can tell they are still G9x based, certainly not using the desktop GTX2x0 or GTX3x0 tech.

 

They're nerfed 40nm G200 tech.

Nvidia couldn't get anything larger to shrink down to 40nm. G214 and G212 were scrubbed.

 

Agreed, Histidine. Even now, if you want an upgraded HP DM3 (which is sold everywhere including Wal-Mart), you have to get it from HP if you want the 4330. Hopefully manufacturers will start waking up to the fact that GPUs aren't just for gaming anymore, and normal people are even beginning to see them as critical for performance.

Put high end GPUs in more notebooks and put them on the shelves, and they will sell.

 

Ouch, that's half the score of the desktop 5770.
But why would they release it with GDDR3?

 

That is a bit underwhelming, now I see what the fuss is about. If there is no real improvement over the last generation, then hopefully the power envelope will be low enough to put them in 13-15", and not cost so much.

This is when we need NVidia to come out with something that blows the doors off of ATI's offerings so that we have some competition. I have a suspicion, though, that Fermi is not going to be as good as we may have hoped. Every time either ATI or NVidia delay their parts repeatedly, we end up with things like the FX 5900 and the HD2900. I hope I'm wrong on that one, though.

 

It's probably much cheaper, and most of the people doesn't look at what type of memory GPU uses. They just look at the number. Needless to say that using GDDR3 in Mobility HD 5850 reduces it's performance to something like Mobility HD5770 (judging from HD5650 results), and considering that the former has 2x more shaders, ROP's and TMU's, not using GDDR5 is like a murder on it's performance.

Still it might be much faster in real-life use in lower resolutions without AA. But who buys a high-end mobile GPU to play on low resolution?

 

The 5870 is a step forward in terms of power consumption, thermal capacity, and efficiency. But performance is increased by only a small amount, the cost of a 128-bit memory interface.

All eyes are on Nvidia. I don't really know if a 256-bit 40nm GPU with GDDR5 memory and under 100 Watt TDP is even feasible at this point, but Nvidia will curbstomp the Mobility 5870 if they can make it happen.

But still, I wouldn't be surprised if the 380M is 128-bit. Honestly, that's what I'm expecting.

 

ATI designed it to be used with GDDR5, not GDDR3. It's more of the OEM faults than the 128bits bus.

 

They've designed it (5850) to be used with DDR3, GDDR3 or GDDR5. It's up to OEMs to choose which type of memory they'll use. On the other hand, the 5870 is designed to be used specifically with GDDR5.

 

The Mobility 5850 is probably won't be seen with GDDR5, ever.

 

You can run two Mob. HD5870 at 100W and two Mob. HD5850, with or without GDDR5, for less than the wattage of a Mob. HD4850+ or GTX280M. What's more if you compare the desktop HD5870 to the HD5770, the HD5850 to the HD5750, or any of the Mob. HD 5800 to the Mob. 5700 GPUs the power draw doesn't double when you double the processors and memory bus.

Maybe Nvidia might have problems doing it with their architecture but I have a hard time believing it wasn't feasible for ATI to make a 256-bit GDDR5 40nm GPU.

 

GDDR5 shouldn't even cost any more TDP than GDDR3. The only problem really, is increased thermal output.

Is a redesigned 40nm G92c with GDDR5 really too much ask for? It should be easy enough to shrink, and would easily match the power of the original GDDR5 forefront, the desktop HD 4870.

 

I'd expect more info would have leaked out by now if Nvidia had TSMC shrinking another new GPU for March.

I'm not expecting more than another 55nm G92 rebrand but maybe they'll put GDDR5 on that.

 

I seriously doubt it since the G92 doesn't even have a GDDR5 memory controller I would rather expect a pumped-up GT21x with more SP.

 

Oh my goodness that is so awesome

 

which is better the ATI 5730 or the Nvidia 230m?

 

5730 surprisingly has 400 shaders, equivalent to 80 Nividia shaders. Core speed is really high at 650mhz.

230M has 48 shaders, and core speed is only 500mhz.

5730 is easily 30-50% faster. It's faster than the 335M as well, and should perform similarily to a GDDR3 GTS 250M. Ati's 40nm fabrication process is maturing, thus clocking their 5000 series really high.

 

^^^
thank you very much Asus N61jq it is

 

Is there such a thing as a Mobility Radeon 5740? I was just browsing over the web over the Ideapad Y460 specs and saw the graphics card listed. The ones I know about is a 5730, 5750 & 5770.

 

There's a Mobility HD5470.

 

Oh well. Must be some recurrent typo...slashgear and laptopmag mentioned it in their articles.

 

I did see this too. Strange, perhaps another version of the 5750? Or a typo...
