Release Dates - Radeon HD 7000 Series

It is one because there is usually what they call a "tick tock" release. The tick will involve a "shrinking of process technology of the previous microarchitecture" and a tock is a new microarchitecture.

But we have had two tocks and no ticks and now we are having a tick tock at the same time (one from the shrinkage and the other from the new microarchitecture GCN). From there come my estimates of 30% to 50%.

But AMD don't tick tock. Intel do.

This has very rarely happened and is a model ONLY Intel follow in general.

Most of the ARM guys are bringing out their new A15 cores on 28nm, new architecture, new chips, new process.

2900xt, new gen, new process(actually designed for 65 and 80nm, both new), HD4000/6000 series are the only ones on a "old" process lately, and both had odd situations. THe 3870 was just about the worst shrink, and rushed, in history, and 6870/6970 was because of a process being dropped.

30% is FAR to low, 50% is likely the lower end ball park, but people really need to work out what can happen with hugely new architectures, some area's it can spank the old gen, and some it can be equal or worse. In this case I think that means in certain circumstances a 7970 could be over 100% faster than a 6970, and in others maybe as low as 50-60% faster.

The driver should also improve a lot, right now the driver does most of the scheduling for Vliw4/5 architectures, meaning the driver has to do a LOT more work than the equivalent Nvidia card that has hardware scheduling. With GCN AMD is moving to a more efficient and hardware scheduled architecture. It will be a LOT more predictable in its performance, easier to code for and easier to fix problems for most likely.



My guess would be 7970 £300-330, average 75-80% faster than a 6970, but this will be excluding a bunch of daft cpu limited tests. IE look at tech powerup and their usual insistence(they seem to be improving slightly) on doing comparison percentages while including a half dozen severely cpu limited benchmarks which frankly doesn't give a real life picture of what's going on.

Waits for DM to appear and write an essay on how wrong you are :) You are btw, drop to 28nm and new architecture, 10% is comedy gold ;)

unless total overhaul i bet the like for like say cards are about 10 fps if that better .

with bf3 being the hardest game youll run for next year min im not bothered ;)
 
If they do have manufacturing problems, I hope it won't cause the price to be too high. I'm hoping for a nice 7970 to replace this 6850!

Hmm Drunkenmaster......wasn't that the chap who talked up the Bulldozer for a fair old while there ?
Click to expand...

No, Martini went around making statements about what everyone else said, like months later right before release he goes around saying "person x, y and Z were all saying this thing that turns out to be wrong, while I was saying all the right stuff, look how great I am, internet e-peen to the rescue". However he's full of crap.

I at no stage talked up Bulldozer as smashing anything performance wise, I said repeatedly that it could do less instructions than a 2600k and that would hurt it, that cores don't matter, that architecture does, that it was designed for throughput rather than threaded performance. Its a little under where I hoped it would be, and in no way a failure. Its one of 2-3 steps into a top end APU platform, though Bulldozer is more of a server chip itself for now.

Go back through the early posts of the Bulldozer thread and see me saying it COULD be great in certain places but it had very narrow cores, I actually got it slightly wrong as SB isn't quite 4 cores with 4 instructions per core, nor is Bulldozer technically a 2instruction wide core, its 2 interger pipes(which is what I was refering to) but thats not the be all and end all of performance.

Bulldozer IS incredibly interesting there is a crapload of "new" stuff that hasn't been done before in it.

The reason I was INTERESTED in it, was it was entirely new, architecturally its the most interesting chip since Conroe came out(even then it was the earlier mobile versions that were the interesting ones).

C2D was great when it launched, earlier versions didn't have the speed to beat ath 64 equivalents, neither were they designed to.

The l3 is for server applications and likely makes smeg all difference for the VAST majority of non server applications. People seem to get held up with the max amount of threads it can run at one time, pc's have been running 50-80 processes at a time for the past decade, and thats at idle. Take a server its not running 8 threads, but probably closer to 800, its how they switch between threads, how efficiently, L3 is stupid important for that.

Look at SB-E, super mature process, uses more power than Bulldozer, is 35% bigger and has more cache, yet only 10% more transistors. That shows just how GOOD bulldozer is to fit 2billion transistors into 315mm2, I said all this at the time but people were comparing it to a 2500/2600k, which performance wise for desktop is fair enough, but also not what it was designed for.

Most of the reviews I have read indicate that SB-E uses slightly less power than BD (at idle & load), even though it uses more transistors on a similar process. Comparing the two performance wise makes poor reading for AMD, with the Intel being ~50% faster within most single and multithreaded apps alike. Where AMD wins is on price when compared to the top end SB-E chip. Within the server market BD's pricing will make it attractive, even if it's performance is "last-gen".
 
Well, it has been announced by a 3rd party, HP, that some of their laptops will come early next month with 7000s series parts so there it goes...

HP's Pavilion dm4 line is also being updated, but the update there is a milder one. Beats Audio and subwoofers are being included in both the regular dm4 and the dm4 Beats Edition, which comes in a sleek new black chassis with red accents and a slick-looking red-backlit keyboard. The dm4 series will also be upgraded to optional AMD Radeon HD 7470M graphics. The regular dm4 will have a starting price of $699; the Beats Edition at $899. Both are expected to be available on December 18th.

What is a HD 7470M?

If its just a 6xxx series with a mild clock bump then perhaps its not really indicative of the "real" 7xxxx series.....

God I hope this is correct but I see the source is Fudzilla, I waiting for the 7850\70 mid range cards anyway, never buy the top end.:D
Click to expand...

I never buy ultra high end, the mid range has always been the sweet spot for me and many, due to how well the card can render games, cost, how long it lasts while in use in your pc (i can cope with 30fps).

Out of all of these the mid range is usually tops due to everything.

With my spending habits i only bother with mid range and high end never ultra.

well, as long as it is 28nm that is what matters. Anyway it gives us an indication when some more cards might arrive. But now we now there will be some 7000 series cards before end of the year.
