AMD HD7XXX Series - Latest leaked details - Chiphell

OP: http://www.chiphell.com/thread-299051-1-2.html

"Double confirmed" means confirmed by official emails inside AMD; "double checking" means the message has been mentioned once in an email inside AMD but needs further confirmation by a second email.

1. All the HD7XXX series products are just rebranding products. (Double confirmed)

The low-end cards of HD7XXX series has been received by the OEM manufacturers now, with the following naming scheme:

http://i1097.photobucket.com/albums/...wwlhr7e7ib.jpg

The HD57XX and the HD67XX have always been the key to the mid-low ranged market, then what about the HD77XX?

http://i1097.photobucket.com/albums/...6mut0iudld.jpg

First possibility, the HD7770 has 2GB VRAM, and it is castrated from 6950/6970. (Double checking)

Second possibility, the HD7770 is an HD6770 with BIOS flashed (Double confirmed), with 1GB VRAM.

Here is a key question regarding power consumption, VRAM and performance:

If it were castrated from the HD69XX, then according to the basic mathematics, how many SP in VLIW4 must be castrated in order to match the same performance and power consumption of 800 SP in VLIW5? It is known that the 5770/6770 is at around 100W power consumption (rough estimation), and the previously leaked NG cards don't need any 6-pin auxiliary power connectors, where the hell does HD7770 aim for?

2. AMD will drop the current "HD" naming scheme and use new trademarks and rules on the NG architecture. (Double checking)

The NG is not yet taped out, so there is no way to know the details of architecture and performance. However the current specifications of power requirements have been given to the manufacturers.

The NG will feature high-end, mid-ranged and low-end product lines but not the same unified stream processors. (Speculated)

3. AMD has teamed up with a big manufacturer and a big brand, to make a top card like the ASUS ARES / Mars II, in order to gain the halo effect. (Double confirmed)

Recall the AMD Radeon memory, if AMD can acquire a hard drive company, then it is possible to build a rig "Intel-free".

Tahiti has met more problems than GF100 did.

It's a big challenge for Tahiti to get an early release, due to very large die size, 384 bit vram bandwidth, very low yield, new tech like PCI-E 3.0 and higher vram clock.

The top 28nm graphics card based on single-GPU (not necessarily Tahiti) should be able to get P45,000+ in 3DMark Vantage.

However AMD blog just increased the credibility of XDR2:

Also, this is nearly impossible now that Seagate owns Samsung's HDD business and WD owns Hitachi's. There's nearly no HDD companies left in the world to buy... :(

You know i don't take chiphell words as it was fresh ... we all know till 3 months( AFDS - august 2011) the low end will be made of 6970-6950 ( middle series ) and possibily 6870 in 28nm... with a luck the 6870 ( aka 7500 ) will just be a revamped 6870 in VLIW4 instead of VLIW5. ( 6870 for a simple reason, this is what you will find on Trinity gpu )

For Thaiti, we have the invert question running around, TSMC is still a problem for 28nm, but less of what it was with 40nm. the chips are ready and allready running in ES system since some months ( this mean more of a test product have been made )..

Offcourse, this is really challenging, as we speak about a GCN new architecture ( a complete new architecture, who are there for define the new base of what computing will be ), new process, and new PCI express specification ( PCI ex3.0 ).. this make a lot of "new". And we need ad to this all the new standard on memory side ( no, no rambus confirmed, i speak about, the x86 memory instructions I/O who will be used on GCN, who will allow to use the Vram and System memory as it was an unique virtual memory system for increase computing interoperability between gpu and cpu ) .

7770 = 6770 = 5770?????

I hope not, thats poor. I slammed nV for it and i'd slam AMD in the same way.

agreed
i wouldnt be to pissed if 7770 was a 28nm 2g 6870 with a few tweaks though
or if they get the 6770 doing ~1ghz at least then it would be a worthy improvement

So if all the HD7XXX series products are just rebranding products, then Tahiti will be HD8XXX, yes? :rolleyes:

Rebrand
Rehash
Release

Everyone is taking a leaf out of Activision's books these days.

Wait, these can't both happen... so I wonder if they are both "true" in the sense that AMD is considering using one possibility or the other as the chip that will be called "HD 7770," but it hasn't been decided yet?

I'd say if this is true then it makes sense to use HD 7xxx on HD 5xxx/6xxx rebrands. I don't have as much of a problem with a "rebrand line" like (supposedly) HD 7xxx per se, but if it exists mainly because the "new" generation is delayed, then I have a problem.

They're rebranding midrange and lowend cards!? Stop the presses!
..Wait, don't they do this nearly every time?

I very much doubt anyone here cares about pricepoint crap anyway. It's the big fat high-end die that xs is waiting for (if at all).

i wouldn't call 4 cards out of a lineup "All the HD7XXX series products" but i'm still never a fan of rebranding

If the low end cards have higher memory bandwidth and core clocks then I can at least see AMD justifying it this round. Lower power consumption + increase in performance will be a great sell to Dell etc.

But as noted I think we're all waiting on the high end. I really hope the HD 7770 turns out to be a 6870 replacement. It would be really nice to get that kind of performance for ~$100

You are in luck. Guess what that ~130mm2 GPU was...

For gamers it makes no difference re-branded 6 series or not. A console port doesn't even pressure a 5850 @ 1680x1050. And as all we PC gamers get is console ports, what's the point in upgrading anyway? I don't think I will need to upgrade my vid card until the next generation of consoles have been on the market for at least 6 months.

I accept that for hardware enthusiasts and those seeking overclocking records there is a difference.

I completely agree with you, but some people here think that you need tri SLI 3 Gb GTX 580s to play the latest games smoothly at 1920x1200 resolution :rofl:

There's still plenty of use for extra performance like Triple monitors, stereoscopic 3D, SSAA etc. And personally I've lost faith on SLI/CrossFire and will be switching to a single GPU when next gen emerges, whatever it might be called. I guess AMD could do a name switch for GCN cards since it's a completely new architecture. The rest of that speculation made no sense to me whatsoever, outside rebranding low end cards which happens all the time.

My thoughts exactly. It's good news in a way since I'm cheap and hate to spend money. Obviously the bad part is that we're not seeing any cutting edge graphical stuff being released these days. I'm not sure if that upsets me anymore since most games seem like the same old stuff. Has anything really novel happened in game design over the last five years or so? I'm either getting too old, or I've just seen it all.

Exactly.

In a way, it's amost a relief that consoles have kept things back in terms of game development, but graphics cards have kept improving. Only because 3*1920*1080 eyefinity can be done on a single card solution without cutting too many graphics options. Because I'm one of those idiots who might spend double the money if it wasn't possible :D

Can't see myself using 3d though. At least that saves me half the burden.

EDIT: On topic, rebranding sucks. Will wait for the 8000's.
