Hehe. Anyone want to guess the clocks? There's enough information to estimate that from the first link alone
It's teraflops btw, not terabits.

This is what we know for sure so far.

R6xx/RV6xx common features:
UVD = Universal video decoder, supposedly 100% video decode offload even for h.264
Built in HD audio controller for HDMI output without needing extra cabling (!)
Dual link HDCP content output capable, (G80 can only output HDCP content at single link rates! Don't know if they changed this in the coming G86/G84)

R600:
80nm HS process
Smaller die size than G80
Single chip, unlike G80 which needs the NVIO chip
Built in audio controller(!)
320 scalar unified shaders/ALUs/stream processors
~16 texture units
~800MHz clock speed for top end
512bit memory bus
improved ring bus architecture

RV630:
65nm process
~150mm²
128bit memory bus
120 scalar unified shaders/ALUs/stream processors
~8 texture units

RV610:
65nm process
~80mm²
64bit memory bus (don't know if it can go up to 128bit)
40 scalar unfied shaders
~4 texture units

what d difference between teraflops n terabits?

Let me guess R600 it should go somewhere around 640MHz?

tera flops (FLOPS-Floating Point Operations Per Sec)

tera bits (a unit of binary data, either bandwidth or storage space )

err...

So teraflops involve enermous amount of data relative to terabits?

No, they are different units of measurement meant to show different things. Anyway, please use google or the QnA section for such questions, i don't want this thread polluted with trivial posts on basic definitions.

Didn't i tell you to stop you goddamned spam fag?!

Please lah, google for mundane questions, and STOP POSTING FOR THE LOVE OF GOD!

shit they keep delay the relase date la.. from feb to may now to june summore... they card not enough power to fight with Nvidia then keep finding solution? Or AMD new proc not rdy so they wait to COMBO attack since they are same BOSS ?

It's 800MHz for 512GFLOPS a piece

320ALUs*2FLOPS*800MHz = 512GFLOPS

The reason for the final delay is in the very first link. It's strategic, not technical.

Graphic card power consumption is going crazier !

G80 is already 180W, so it's not that much worse, depending on how well it performs. I've heard however that things are not going to get any worse than they are now, in fact i think next generation might be better. AMD's upcoming midrange chips RV610, RV630 should be good with power consumption, from all current indications (128W that's been thrown about is wrong AFAIK ).

Yes, these DX10 GPUs are insane. The cooling is much tougher on graphic card than CPU. Well, i guess the developers have no choice if they want great performance. Do you heard of any upcoming ATi GPU with less than 50W?

I don't care bout the power consumption as long as it perform well. Performance is the first priority to me.

GPUs are behind CPUs in terms of power saving features and low power design, for sure. However a lot of that power is also used to power the gobs of high speed memory on the board, CPUs don't have the memory in their power budget. I dunno, i heard many things...


Power requirements cannot keep growing at the current rate. You better care because if things were to continue this way you'll have to buy a more powerful air conditioner every time you upgrade. It's bad for the environment, it's wasteful, and it's just plain dumb to keep increasing power requirements like that.

Believe it, it will kept growing, and you can't simply compare to CPU. All those pixel processor, stream processor and 1GB of memory sucking tons of power. Its inevitable and unavoidable, you want ultimate power, you have to make ultimate sacrifice (new PSU, more sophisticated cooling etc). No matter how much noise we make about this issue, they will simply ignore it and still release this beast. Buy midrange cards if you cant keep up with the heat, or get out of nuclear reactor

I still remember the good old days, how simple past high-end card was, especially the GF4 Ti-4600, great speed and simple single slot cooling, and midrange GF4 Ti-4200 can simply be overclocked to Ti-4600. I don't believe future high end card gonna be the same

Yeah, those memory takes a lot of power actually. 1x16MB GDDR3 1000MHz Chip probably consume ~2W. 8 of them (128MB GDDR3) will have ~16W already, hahaha.
Now the 8800GTS with 320MB GDDR is running at even higher speed. The RAM chips alone took up more than 50W


Hopefully the next generation graphic card can stay at 150W range, just like CPU nowadays. A good hardware designer should watch for power consumption and silicon size, not just simply adding buffers and increasing bandwidth.

Practically, that cannot happens. I mean yes, requirement will go up, but eventually engineers will have to find a solution to it, it cannot keep growing no holds barred. engineers will not ignore it because if your competitors can come up with one that doesn't need a nuclear reactor power supply and a vacuume for cooling, you're heading for a doom. Remember how 5800Ultra was blasted for its loud cooling solution.

This is what designing new hardware architecture is all about. Everything including power consumption have to be taken into account. It all sums up to efficiency. Growing in performance with a equal growth in power requirement will means there's absolutely no improvement in its efficiency.

For those who didn't already know...
R600 (and RV6xx) is a sound card too. Built in HD audio controller. Very many interesting possibilities may be enabled by this...

I don't understand German, but the slides are in english. UVD ftw.

Now that's definitely new I can't imagine how much noise it will actually introduced to the port (with all the vibration and big fat fan running) hehehe or they might really do a great job and pull it through with this new innovation. Definitely worth a wait.
