AMD's Radeon HD 7000 Series

AMD promised us that by the end of this year the company will come up with its first graphics cores from the HD 7000-series, and these GPUs were just announced today.


 Contrary to what everybody has thought however, the chips cover the notebook sector and are nothing more than rebrands of previous HD 6000M parts.

Traditionally AMD has launched its new series of graphics cards at the high-end and then continued with simpler solutions until it reached the value sector.

This time however things are different, as AMD has decided to start with the mobile version of these chips from the Radeon HD 7000M series which are nothing more than rebrands of their old Turks and Caicos GPUs.

While most of us were expecting Southern Island products based on TSMC’s new HKMG 28nm process, the fact of the matter is that TSMC is running late with its 28nm technology as yield and production capacities aren’t where they should be to allow for a 2011 launch of such products.

According to AnandTech, this left AMD in a particularly tough position as the company was concerned that they needed to get new mobile products out by the end of the year, so they were forced to make do with what they had.

There are some indications that 28nm parts could still arrive until the end of the year, but a complete launch is out of the question.

Moving to the parts that AMD introduced today, we see three products being released. Of the three, the Radeon HD 7600M and HD 7500M are based on the Whistler core (previously Turks) while the HD 7400M uses the Seymore XT GPU (previously Caicos).

Unfortunately, details for the new 7000M parts are lacking right now but the new parts should sport higher clocks than their predecessors.


All the HD 7000M parts can be configured with both GDDR5 or DDR3 memory depending on the price segment they target, and feature either a 128-bit or a 64-bit wide memory bus.

Of the three series announced, the HD 7500M is particularly interesting as it comes to bridge the gap between the HD 7600M and HD 7400M by pairing a 480-shader Whistler Pro GPU with a 64-bit wide memory bus.

This is of course going to hurt bandwidth, but notebook makers could still deliver some worthwhile solutions based on this GPU if they pair it with GDDR5 memory, which could enable the GPU to reach the same bandwidth as a similar 128-bit DDR3 equipped model.

All the Radeon HD 7000M parts announced by AMD today should already be available in quite few notebooks, so we should be able to see soon enough how these perform in real life scenarios.

Dropped the ball again? Or maybe a marketing ploy? Who knows....

Some more reading for you techies: http://www.brightsideofnews.com/news/2011/11/30/radeon-hd-7000-revealed-amd-to-mix-gcn-with-vliw4--vliw5-architectures.aspx

That article includes some insight into the HD 7950, 7970 and 7990


Quote
Tahiti becomes HD 7950 and 7970, New Zealand becomes HD 7990
Now that we're properly introduced with the GPU core, the time has come to pay more attention to the lineup itself. Given that the memory bus was extended to 384-bits, i.e. the same as GeForce GTX 580, 3GB GDDR5 are being used across the board, and we would not exclude a 1.5GB or even 896MB "7930" part coming as the number of partially functional GPUs increases.

AMD kept the unified clock concept and given that Radeon HD 7970 is based on fully configured "Tahiti XT" GPU, 2048 cores (32 Compute Units) operate at 1GHz clock. 3GB of GDDR5 memory operates in Quad Data Rate mode i.e. 1.37GHz ODR ("effective 5.5GHz"). This results with record video memory bandwidth for a single GPU - 264GB/s.

The HD7950 is based on "Tahiti Pro" and packs 30 Compute Units for 1920 cores operating at 900MHz. The number of ROPs decreased to 60, while Texture units naturally reduced to 120 (as every CU connects to 2 ROPs and 4 TMUs). Our sources did not disclose if the memory controller is still 384-bit or a 256-bit one, but the memory clock was decreased to 1.25GHz, i.e. the same clock as previous gen models. Should 384-bit controller stay, the clock should be good for 240GB/s of bandwidth.

Both products are expected to be released on CES 2012 in Las Vegas, NV, occupying the $349-449 price bracket. Those additional gigabytes of memory (and processing cores) will certainly cost a lot of $$$.

As far as the dual-GPU "New Zealand", 6GB GDDR5 is expected to be clocked on the same level as the HD6990/7970, meaning you will be getting full performance out of the dual-GPU part.

Unlike HD7950 and HD7970, Radeon HD 7990 will debut in March 2012 and the target price is the same as the original price of its predecessor - $699.

Rebranded parts from last generation masquerading as new parts with a fresh sticker on them? Hell I could think of another green coloured graphic card maker that are experts at this as well!



But on another note..

Amd's hardware always sounds very promising on paper but in reality

1) lack of proper quality control on the part of their board partners resulting in simple stupid things like malfunctioning cooling fans after very short time periods (happened to me twice, different brands)

2)  poor drivers especially in multiple cpu configs,

3) poor "legacy" support as in ONE generation behind

4) slow updates and general stability of driver code (or lack thereof)

....was and CONTINUES to be a major barrier to AMD's success over their competitors who, while not perfect, in my experience are miles ahead in the above mentioned aspects.

Until that changes, AMD will not see another red cent from me, no matter how financially competitive their products are.

this i know

and i also do agree with your statements

just one thing, i dont agree with their driver issues, it is not as big as ppl make it out to be!

That is true Awesome. Their drivers, though may be released later than Nvidia's, are up to par atm. Arcman has no issues, neither does Chris, neither to I atm. Berserk doesnt count since he trying a fast 1 and running 2 different GPU's with 2 different sets of drivers installed at the same time  :shakehead:

You'll have to talk to him. Something about BF3 not working if he's playing Batman which uses the phsy-x. And vise versa, cant play Batman if he's playing BF3. No clue

that was my issue with getting Physx to work on Batman Arkham City with some other issues with Battefield 3.

What happened was when battlefield patched, (I believe it was last week, it must have updated the  physx drivers, making the older version physx previously installed, incompatible with Batman (thereby causing issues)
 For Physx to work with Batman it needed an older version of the Physx drivers with the physx hack. . Once I figured out the issue, all I had to do was run over the physx patch, reinstall older drivers and presto problem solved. No more issues. I was able to run BF3 last night no issues.

Didn't bother to really dig up till recently cause the only game  I cared to have working was the Batman. (which worked admirably till some scenes in late game required me to lower physx detail.)


On a side note, aside of this physx issue, I have ZERO (0) issues with my 6950 (unlocked to a 6970 mind you) and my 1100t 6 core. (+12 gigs o ram)

Able to play most games at 50+ frames on max, and those that can't are usually games known to have issues. Just saying.

Can't speak for the experience of others, but for sheer price per performance for gaming, ATI/AMD hitting sweet spot for me.

I'm on the AMD camp (back again from a small stint with the green team)

Have to agree with virtue, captain, et al.....The cards working like a boss.

How many of you running dual cards? Single might be fine but try dual cards nah, I double dear you. TWO generation of dual gpu cards did me the same nonsense with Bad Company 2.

How long after bf3 did ATI release decent drivers for their cards, esp the older ones?

The only persons running a dual gpu AMD card is Cpt Chris with his 6990 and me with W1nTry's 4870x2, not aware of anyone else atm. Doesn't give any problems now tho, at least i'm not afraid to alt tab out the game like Chris =p. But yes, they didn't release a driver update till about 2 weeks after the launch, it really only affected me though. Preston and WarOne who had single 4870's were fine.

And on the other hand, Nvidia had beta drivers specifically for BF3 the day before it released...ones that were almost perfect.

Yes yes we know, we know... AMD seems to be dropping the soap.. i mean ball all around. But we see it from the consumer end, it must be very disheartening to be the developers behind this tech subjected by a marketing board and deadlines. The pressure of competition usually leads companies to make poor decisions and fumble. Very easy to criticize when we don't have the full picture.

Performance vs cost tho, AMD still has good products for decent prices, without which, a lot of gamers here wudnt be able to afford a system in the 1st place. Small graces i suppose
