Aye, I gave up trying to figure out if you should wait or buy now. I started telling people just buy what you can afford when you're ready to buy and do not worry about the next thing. If you do, you will never buy.

For the ones that don't see how a 256-bit bus can outrun a 320, or 512-bit bus. I guess a good example would be the 6600GT outrunning the 9800Pro on quite a few occasions. Just rambling here.

I can say this, I am *ALMOST* ready for a complete rebuild. I have been telling myself *NOT* to buy a 8800GTX, GTS or 2900XT and wait for the refresh. Thank the good lord were almost there. But regardless of what I choose...may it be the 8800GT or the RV670 still remains to be seen.

Here is my last few years of cards owned....

ATI 9800Pro
ATI X800Pro
C3D X1800XL
HIS X1900GT
eVGA 8800GTS 640
BFG 7900GTX

The card I have now, the 7900 GTX and while its *STILL* a nice card. I can easily tell that the IQ is no where near of the ATI cards i've owned...and also no where near the IQ of the GTS 640 I had. So
I would like to try a next gen ATI card. So here's hoping all turns out well this time for AMD/ATI. ( Come on AMD/ATI....I for one *KNOW* you can get it right this time

My rebuild will consist of

Dual OR Quad Core CPU
2 x 500 gig
( Insert graphics card here )
4 gig memory
Vista 64-bit

See I WOULD wait but I wanna sell my GTS before any of the cards hit so I can get a decent amount of money for it, unless of course all the new cards are slower than the GTS 640. This is what I'm a bit hesitant about. Where these cards slot in is a bit of a mystery so I don't wanna get screwed over.

No pain no gain I suppose...so I'll definitely put it up for sale and hope that the R670 performs well. I wonder if DX10 performance will be improved.

That's with completely different architectures though isn't it? 2900XT-->R670 isn't that big of a difference I don't think? That's why it's sort of hard to believe. However, as munky said, there's a lot more to it...at least I hope it turns out that way.

 

[JPB]

Suppose to built on a smaller process, cooler running. And is'nt it suppose to have hardware AA instead of shader resolve AA ? If so..wouldn't that greatly improve AA performance ? There is also suppose to be enhancements to the core. What they are ? I don't know.

If they can get these out at $250 I would for the first time consider a dual GPU setup for my new rig. With close to 2900xt performance, two of these for $500 would murder a GTX.

i would just try it with my current 2900xt ... for $250 ... if it is really almost 'just as fast' ... i still would consider it with an OC'd 2900pro but i can't find one for MSRP

and i start to think .. if the 2950p will performs close to a 2900xt for $250, what can we expect from the new flagship 2950xtx?

XTC ... or another r600 debacle when nvidia releases their new GPU?

I think AMD did a good job at confusing the hell out of us. All I know is that AMD is not planning on releasing a high end card anytime soon, right? All these cards are just die shrinks that don't hurt the wallet much.

I think that will be ok. I've seen the 2900XT benchmarks and they perform very good. Beating the 8800GTS in some. If they can only offer them at or around the same price as the 8800GTS, AMD could make some good money. The only problem I see is that AMD will be late again.

Two weeks after the 8800 GT isn't late.

 

[bryanW1995]

yeah, if they're 6 mos late like r600 that would be "late". two weaks later is "early" by DAAMIT standards...

ATI Radeon HD 3870, the one on the second picture will feature 825MHz core and 2400MHz memory clocks, DirectX 10.1 support, and PCI-e 2.0 technology. ATI Radeon HD 2850 on the third picture will be clocked at 700MHz/1800MHz core/memory with DirectX 10.1 support and PCI-e 2.0. Both cards will feature 55nm manufactured graphics processing unit (GPU).

This just keeps getting more interesting by the minute

Does that mean, according to the post by dennilfloss...That the RV670 will have somewhere around 77 GB/sec bandwidth ?

HD 2900XT

Core Clock:...............743 MHz
Shader Clock:............743 MHz
Memory Clock:...........825 MHz (1650 DDR)
Memory Bandwidth:....105.6 GB/sec
Shader Operations:.....237760 Operations/sec
Pixel Fill Rate:.............11888 MPixels/sec
Texture Fill Rate:.........11888 MTexels/sec

HD 3800

Core Clock:................825
Shader Clock :............825
Memory Clock.............1200 MHz (2400DDR)
Memory Bandwidth:.....76.8
Shader Operations:
Pixel Fill Rate:
Texture Fill Rate:

If someone can fill the rest of it out, please do. I cant remember the exact way to do it now.

 

[bryanW1995]

I don't know how to do it, but you left out memory fill rate and put its number under shader ops.

 

[JPB]

Fixed.

I think

Thanks for getting us back to RV670 (the upper mid-range refresh for R600). Ppl have been confusing the issue by referring to R670 (pointers suggest a high-end dual-RV670 single-PCB card due early 2008).

HD 2900XT

Core Clock:...............743 MHz
Shader Clock:............743 MHz
Memory Clock:...........825 MHz (1600 DDR)
Memory Bandwidth:....105.6 GB/sec
Shader Operations:.....237760 Operations/sec
Pixel Fill Rate:.............11888 MPixels/sec
Texture Fill Rate:.........11888 MTexels/sec

That should be 1650DDR for the XT

HD 3800

Core Clock:................825
Shader Clock :............825
Memory Clock.............1200 MHz (2400DDR)
Shader Operations:......76.8
Pixel Fill Rate:
Texture Fill Rate:

If someone can fill the rest of it out, please do. I cant remember the exact way to do it now.

Because it's based on the same core design, you can derive the fill rates from the increase in clock speed (+11%), i.e.
Pixel Fill Rate:.............13200 MPixels/sec
Texture Fill Rate:.........13200 MTexels/sec

 

[dennilfloss]

So, does it look promising for a mid-range card with those specs?:laugh:

HD 3800

Core Clock:................825
Shader Clock :............825
Memory Clock.............1200 MHz (2400DDR)
Memory Bandwidth:.....76.8
Shader Operations:......264000
Pixel Fill Rate:.............13200
Texture Fill Rate:.........13200

Now if the 256-bit won't hurt it much like people don't think it will. It does look to be a bit faster than the 2900. Correct ?

Also since it is 55nm, it may overclock near 1GHz core. How nice would that be ?

 

[dennilfloss]

It would be sssssssssssmoking!!

 

[bryanW1995]

I had a dream last night that rv670 came out and destroyed 8800 ultra. If that happens then I will take back all of the nasty things I've said about hector lately...

[bryanW1995]

nice grab. I think that I would prefer the dual slot cooler design. It will probably be a little bit quieter since the fan won't have to spin up so much, plus it will exhaust the air out the back like the old cards

 

[dennilfloss]

The fan blades do look deeper than on my 1900XTX though.

[dennilfloss]

His link says 3850 and not 2850. Makes more sense.

 

[bryanW1995]

yeah, 2850 was probably a typo.

 

[SniperDaws]

Bryan why on earth do you want a new graphics card? The graphics of Anand forums wont get any better with a DX10 cards mate

toms is the source

Although i can't speak for anyone else, i felt my x1950p/512M was insufficient for my planned and now completed upgrade using a 16x10 LCD; my 2900xt does the job nicely - and evidently 38X0 series also - although all current GPUs lack when it comes to DX10 and it remains to be seen how the new GPUs perform.
