The purported leaked AMD 67xx series spec sheet (click to enlarge).  (Source: Chip Hell)
Upcoming 40 nm GPU will offer some sweet gains, if leaked specs are to be believed

A member of Chinese-language forum PC In Life ("gf6600") has leaked what appears to be Advanced Micro Devices' spec sheet for its mid-range members of its 6000 series.  The leak was validated by site Chip Hell, which leaked a more complete version of the table.  

The spec sheet covers AMD's Barts GPUs, its upcoming mid-to-high range GPU entry, which will be built on a 40 nm process.

If the sheet is to be believed, AMD is about to unload a world of hurt on its competitor NVIDIA in January, when the new cards are expected to start trickling out.  The spec sheet shows two GPUs (the HD 6750 and HD 6770) that clearly outclass AMD's current mid-to-high range offerings (HD 5750 and HD 5770), even rivaling AMD's current high end flagship chips (HD 5850 and HD 5870).

With respect to their direct predecessors (e.g. the HD 5750 for the HD 6750), raw computing performance has been bumped over 60 percent, as has the texture fill rate.  The memory bandwidth, Z/Stencil, and pixel rates have all approximately doubled.

That's not to shabby considering that the second leak (from Chip Hell) indicates that the power envelope has only jumped approximately 30 percent.  While that is generally very good news, the only bad news there is the HD 6770's 150W max power draw likely necessitate 2-pin PCI-e connectors.

If AMD can keep within its current pricing scheme for the new lineup, that could deliver some scary price per performance.  And if this is what's inhabiting AMD's mid-to-high range slot, we can only imagine what monster might be lurking in the high range slot -- dubbed Cayman.

The ATI brand name may be dead, but AMD is clearly carrying on the company's legacy with pride.  Even as NVIDIA turns its eyes to GPU computing and other new markets, AMD's focus is clearly on delivering unbeatable gaming GPUs at their respective price points.

All of the cards in the 5000-series are 40nm and all of the cards in the 6000-series are going to be 40nm. Where's the die shrink?

AMD rebranded their 4000 and 5000 series? I don't think just because they have similar performance number it already means it's rebranded. Correct me if I am wrong.

For nVidia, well I know some of them are rebranded because it's the same architecture, same specs, slightly different clocks.

The 4xxx series does not support DX11 while the 5xxx series does. So there's no way the 5770 can be a rebranded 4870.

Get your facts right.

You really should quit while you are behind. The 4870 was built on a 55nm process, the 5770 was built on a 40nm process. You are trying to link AMD to "rebranding" - the reason "rebranding" is criticized as a practice is because it forces users to buy higher-end products to get the new featureset. e.g., to get DX10.1 in nVidia's GT200 generation, you had to buy at least a GTX460 - but to look at the name of the GPU's, it appeared as though any GTS2xx GPU also supported DX10.1. In AMD's case every GPU (initially, a few mobile GPU's eventually slipped out that did not have it) with a 5xxx name supported the full DX11 OGL4 featureset. They spent the money to develop a full product line - nVidia saved money then made it look like they didn't, but tried to deceive customers about what they were selling to appeal to OEM's and "bullet-point" customers. What nVidia did was to increase performance but given an inferior feature set. AMD increased performance AND increased the feature set. I'm sorry you can't tell the difference, but maybe staging a self-pitying whine-fest in a post later in this thread will be consolation for you.

Matching the number of execution units borders on the moronic. Both AMD's bulldozer and Intel's Nehalem have have the same number of exeuction units (7 ALU's and 2 FP) - does that make them the same in your eyes?

Not re-branded, it's a substantially different architecture. Southern Islands will be even more so.
Since about (I think) the 2xxx series, AMD has used a 5-dimensional shader design. Nvidia uses a one-dimensional shader.
AMD has set up a block of four simple shaders and on complex shader on previous generations. They are now moving to four medium complex shaders per block. This is substantially different setup, and it doesn't even account for the changes in the uncore.

BTW, the jump from the 4 series to the 5 series did use the same process (40nm), and the same shaders... But nothing was just copied over. The uncore was substantially changed in that generation hop as well.

The only 4XXX card was 40nm was the 4770, which was the testbed for 40nm, the rest of the 4XXX series was 55nm. 5XXX series was the first 40nm series. The 6XXX series (Southern Islands) remains at 40nm, the 7XXX series (Norhern Islands) will be 28nm.

If they've managed that speed bump at 40 nm. I can't imagine what 28 nm will bring to us.

In addition to the posters above, the 6 series combines the core of the 5 series, and the back end (ROPs, etc) of the new Northern Island architecture, which becomes he Southern Island. Originally the 6 series was to get a die shrink of 32nm, but since TSMC decided not to pursue the 32nm fabrication, AMD is forced to stick with 40nm for now, and make a jump to 28nm with the 7 series (Nouthern Island).


RE: What die shrink?
By RussianSensation on 9/29/2010 12:20:58 AM , Rating: 3
No, this is incorrect. The sources which initially reported Northern Islands to be a 28nm part mixed up the names. HD6000 on 40nm IS Northern Islands, while Southern Islands will arrive at 28nm next year. You have it reversed (or are quoting 6 months old news). Perhaps AMD intentionally leaked incorrect information to mislead the competition. The bottom line is HD6000 is a brand new architecture, with shaders more efficient than HD5000 series.

Also to the poster who said HD6770 is nothing but a "rebadged" 5870...you do realize that HD6770 will be positioned as a mid-range card while HD5870 costs $350+. This likely means at least $100 lower priced card with performance at GTX470~5870 level with TDP ~ 150W. That's great progess imo.

I think TSMC had trouble with the 32nm node, so they are going directly to the 28nm one or something. Thus causing delays in both AMD and Nvidia products.

I thought the 6700s were going to be released in mid October, with widespread availability in November. and the 6800s were to be released in January. I wouldn't be surprised if the dates have slipped, though. Nobody is gonna want a 5800 after these are released.

I wouldn't be surprised to see dates pushed back from mid-October either but they'd be making a mistake not having them available by Christmas (better yet, Black Friday)

A paper launch would be even worse for sales though, so that wouldn't be a good thing if production yields are not very good yet. Releasing a mid-ranged product for the next generation before the high end would also be a bad thing, since they would be losing out on sales of the last generation high end parts.

In general, you see the high end of the new generation actually available before the mid range parts for this very reason. I know that at this point, those who pay attention may hold off on purchases until the 6870 or whatever it ends up being called becomes available.

What you say is true, but I am sure sales of 5850 and 5870 are already down to a trickle and AMD's hand is being forced a bit by Nvidia's successful GTX 460. They need an answer now in that segment.

Rumored die size for Barts (HD6770) is ~300mm2, which is still quite far below GF100's (GTX480) massive 529mm2, or even GF104's (GTX460) 367mm2. Even though Cayman (HD6870) will be larger than Cypress's (HD5870) 334mm2, it's certainly not going to be as big as GF100, and it will likely outperform it.

I thought 6770 & 6750 was supposed to launch on October 14 or 18.. with 6800 cards and the lower models in early 2011.
