News - More Radeon 6700 specs leak?

[HEXUS]

Twice the horsepower? Yes please!

Read more.

I must resist, I need to keep telling myself my 5850 is enough!

... is reported to have four clusters of 320 stream processors ...

Given they've reported the other ATI cards as having e.g. 320(x5) stream processors, this is more likely to be 320 clusters of 4 stream processors, which would indicate a shift in architecture from having 5 SPs per cluster. What'll be interesting is the arrangement of those clusters, as the cut down 6750 loses 40 clusters. Does this mean they'll be grouped in 20s to maintain the 80 SPs per block of the previous generation? Are we going to see 40 clusters per block so the low end cards finally get a shader boost (to 160)?

And frankly, the rumour mill was that the new GPUs would be a different front and back end with the existing shader model in between. Which makes the whole concept of the new cards having a different shader layout a little... incongruous. So perhaps the slide isn't entirely trustworthy...?

Why is it that GFLOPS ratings are much higher for ATI than NVIDIA despite no significant performance differences?

[HalloweenJack]

the main rumour for the HD6xxx is a move from 4+1 to 4 - which would give what we have here.

I need to tell myself my 4850 is enough! I am so broke but i'd love a 6770 when it comes out! (along with a new Full HD monitor)

The HD6750 looks quite interesting. It seems to have similar power requirements to an HD5770 and hopefully will have performance between an HD5830 and an HD5850. OTH,I hope it only has one PCI-E power connector and does not use a stupidly long PCB!!

If the 6750 is a single 6 pin power connection design then my lan box may get a tasty upgrade

I just want a passive card thats faster than my underclocked 4870...

114W is kind of pushing it for a passive card, but I have no doubt that one of better solutions could make it work (albeit perhaps unofficially.)

What I really want to see this go-round is the 6750 with voltage control. The 5750 was purposely gimped in this regard, for obvious reasons (they've been darn close to $100 since not-so-long after launch and would negate the 5770 if overclocked decently).

Looking at the shader setup, which should be effectively almost the same as Cypress (judging by beyond3d and others showing 3-4 shaders being used when it was 5D) and others reporting Evergreen needed a little bit more engine/pixel fillrate power (~15% iirc), the 6750 should be a DAMN fine cheap mix o' card. I wouldn't be worried about TMUs, GF104 has 64 (56 in GTX460) with fairly terrible utilization ie not very close to theoretical. Since AMD's is ~99% in Evergreen, and games will be built toward GF104's spec (it is the current new 8800gt after-all) I wouldn't be worried about it.

Like I said, just give me core voltage control and I'll be happy. Wouldn't mind if the rivatuner/afterburner guy threw in memory voltage control either like they are with some MSI cards, as I imagine both these cards will use the same vmem settings as the 5750/5850/5970 which is a little lower than the previous 5x70 models. Stock core voltage I expect to be similar.

I've seen lots of prices thrown around, but GTX460 is ~$170/210. If AMD can drive this market to ~150/200...This will be pretty awesome.

Hmmm. Core and memory voltage as well as frequency control might be enough to lose a few MHz and make one of these passive
Personally I don't care for overclocking graphics cards but shutting them up sounds good!

Yes please! I want to move up from my passive 4650...

[CAT-THE-FIFTH]

There is a passive HD5770 available:

But how does that compare to my 4870 underclocked to 500/500

[Terbinator]

I imagine it performs better TBH.

[CAT-THE-FIFTH]

An HD5770 1GB is comparable to an HD4870 512MB AFAIK.
