Concerning next series of graphic card coming up (600m/7000m series)

the new GCN architecture is impressive, but keep in mind 3dmark11 as far as I remember, runs on low resolution for stock testing, so the limited bandwidth of the 128 bit HD7000 card is not really affected yet. If I remember correctly, it's a 70GB/s card, whereas the HD6970m is 100ish. not to mention the new GCN brings better DX11 performance.

also, the 7700 is placed as between the Hd6850 and the HD6770 if I remember correctly. so no wonder it can outperform the HD6970m which is downclocked enough to be outpaced.

And finanly, I can't wait for the HD7900m series. I definitelly want to upgrade if possible, otherwise I will stick to the Hd6990m.

 

If you downclock the HD 7770 to about 600MHz core for the HD 7750M, what do you think the perf will look like?

 

Hypothetically, I will guesstimate it ending up in the ballpark of the 5870M.

P3672 3dmark 11 :|, thats a tad bit better than both 580M and 6990M at stock :|

This means the 7750M most probably is around 5-10% faster than the 7690M. Not as good as some has mentioned.

 

How did you draw such a strange conclusion from those tests?

 

then 7870m is going to be somewhat similar to p3000, I think it is pretty good, now I can believe if gtx 660m will be similar to 580m

 

The HD 6770M/7690M series is based on the desktop HD 6670.

The 6850M is based on the desktop HD 5770.

The 7750M is likely to be based on the lowest of all GCN chips, the desktop HD 7750 as some of you have suggested.

The problem here: HD 5770 @850MHz has similar or sometimes better performance compared to the HD 7750 @1GHz.

If you downclock the parts, you are going to get the 6850M vs 7750M. However, one must consider that both parts seem to be similar performing, and so with the current 6770M/7690M and 6850M gap at between 5-10%, my guess is that the 7750M is about ~5-10% faster than the 6770M/7690M, give or take 5% depending on AMD final clocks for the HD 7750M.

 

are you seriously believing 7750m will be based on the same desktop card?? man, way too optimistic

 

Then which desktop card? The HD 7750 is the lowest series with GCN already. Unless AMD fuse off some shaders, but that will make the 7750M weaker than the 7690M.

 

I think you are on to something. Really, the desktop parts, at 28nm are cool-running and efficient enough to run in a laptop platform without a huge amount of change.

 

Id expext the 7870m to be a 7770 at around 900mhz, 7850m could go either way, a downclocked 7770 or pretty much a 7750m.

 

But you're not factoring in that the 7750 is already 55W; AMD will hardly even have to downclock the thing to reach the target TDP, probably somewhere around 45W. Furthermore, the 7750M would still retain the ability to overclock like mad, gaining back much of the stock 7750's performance and leaving the 7690M far behind in its dust.

Also, I'm not sure where you're getting your numbers, but the 6770M/7690M are not even within 20% of the 6850M GDDR5, unless overclocked.

And please keep in mind that, in this conversation on mobile GPUs, the desktop 5770 is an overclocked 5870M. If the 7750M is anywhere near that, the 7690M has been crushed.

 

Do you guys think the currently available notebooks will be impossible to get hold of once the new f.eks. asus G models roll out?

Should try and buy a G74/G53 pre-april or wait to see if a price drop occurs instead?

 

I would only buy a machine NOW if you had to have it NOW.

There will be dozens of great new choices in late March through early May hitting the shelves.

From all of the industry articles i have been reading, the price drops for a lot of models has already happened in anticipation of Ivy Bridge.

 

600m series in April.

 

Details regarding AMD Pitcairn (78xx) which hopefully should for the basis for the flagship mobility card..

??????HD 7800???????? - ???

Translated (fudzilla - http://fudzilla.com/home/item/25998-amds-upcoming-pitcairn-gpu-detailed )

The specifications of the fully enabled Pitcain based HD 7870 include 22 Graphics CoreNext compute units, or simply 1408 stream processors, 88 TMUs and 24 ROPs. The Radeon HD 7870 will ship with 2GB of GDDR5 memory paired up with a 256-bit memory interface. The HD 7870, at least the reference ones, should be set to work at 950MHz for the GPU and 1375MHz (5.5GHz effective) for memory.

The Radeon HD 7850 on the other hand has two GCN CUs less, for a total of 1280 stream processors, 80 TMUs and 24 ROPs. This one will be available with either 1 or 2GB of GDDR5 memory paired up with the same 256-bit memory interface. The HD 7850 should end up clocked at 900MHz for the GPU and 1250MHz (5.0GHz effective) for the memory.
