Prowl I ain't gonna say this again, STOP the INTEL FANBOYISM. Your topic headings a while now have read nothing but doom and gloom and it ain't warranted. ATI currently has more design wins than nvidia FULL STOP but you wouldn't know that since yuh doh read as much as you should. R700 will come when it comes but in a realistic world where you need money to design, build and market a product time lines slip and things get botched. I don't think AMD was the reason for ATI slipping as at the end of the day its ATI engineers that designed the products they are selling not AMD. If you post another topic heading that is as FLAMBOYANT with fanboyism again I will delete it without warning and without notice.

Winny I might be an intel fanboy but I like ATI!!!! That and I know we need amd to keep intel inline. Ok maybe I over reacted .........

R700 has taped out

Weeks ago actually

By Charlie Demerjian: Monday, 31 December 2007, 10:25 AM

A FEW WEEKS ago, a bunch of people suggested that the ATI R700 would be delayed because it won't appear on official platforms until much later. This was the worst case of roadmap misreading I have seen in a long time, made so much more laughable by the fact that it had already taped out.

Yeah, R700 is in the process of being fabbed now, or at least its components are. The component thing is a story for another day, the part that matters is that R700 bits are in the oven now and things appear to be going swimmingly, or at least skatingly if you know what Toronto is like in the winter.

Rough maths puts silicon back in late January, gone through the initial checks by early February, and then given the thumbs up or down. If they are up, look for boards in about 90 days, putting it in May or so. If it is thumbs down, add about 2 months per spin.

Based on RV670 and R680, ATI is on a roll, and the internal process they put in place seem to be the right things at the right times. Based on that and the fact that the new chip is architecturally similar to the older ones, I would think that it will be close to perfect out of the gate. We will know in a month or two.

Yes I do and redlum has a 360, a PS3 and a 55" Plasma and a 10Mbps internet connection so he too technically can laugh, I have NO INTERNET ATM courtesy of TSTT MCS so I can LAUGH at ur 2400 :p but I guess you could laugh at my TSTT woes...

R700 is coming soon , looks like it will be 30-50% faster than a 3870 based on pure specs .

Though right now the 9600gt and 3870 going for less than 200 US are looking VERY attractive... These new cards should give us reason to wait.

holy crap.. 1TFLOP of procession power on a single gpu.. hmm .. and just when i was thinking about the 9600gt or the 8800gt.. man... this lil upgrade is harder than i thought oui...

W1nTry · « **Reply #9 on:** February 23, 2008, 03:53:46 PM »

Considering the prices of the 8800GT I would say spend the little extra and get it. Otherwise if you keep looking at the hardware refresh cycle you'll never buy new hardware and end up like crixx with an Old P4 rig still saying i'll upgrade to.... wait isn't that... and then.... but wait... also...

haha... I understand you though.. not like this kinda thing never happened. Always occuring, new stuff coming out every quarter.

My excuse is that i have no money to buy anything anyway... So i might as well wait.

Probably going to upgrade octoberish. Starcraft II!

hmm i am actually glad to see ATi is taking a stand on making bang for buck solutions their main focus, kinda good news for a bang for buck pc man like me. I do hope they work on their drivers so that they can get justified performance from their hardware. Their architecture is there, but the drivers seem to be struggling and holding back performance. Hope to see something special from these cards when they release, so that ATi can sit on the throne again for at least a quarter or two..

Well as it is the 3870X2 is still king of the hill eh! so they are sitting on the 'throne' so to speak atm. I figure it'll be short lived as the 9800GX2 will prolly take that crown back, but as a single PCB solution, it'll remain the fastest as the GX2 is a DUAL PCB solution that's not quite as elegant. THen there's QUADFIRE in the works and i'm sure they'll get it down in a month or two. Nvidia on the other hand I can't say has been able to successfully get TRI or even quad sli working... so time will tell. Ultimately TRI SLI with 8800Ultras should be the fastest thing under the sun, but it's also the most expensive under the sun without a justified increase in performance....

Philosophical45 · « **Reply #14 on:** February 24, 2008, 12:06:21 PM »

hmmm, i'm waiting to see that 9800gx2 as well. I'm seeing the 8800gtx's prices drop to 409usd on newegg, so that can mean one thing. The 3870x2 is a massive card yo, but what totally confuses me is the stream processors. ATi's gpus have more than Nvidia's hands down, yet in all the benchmarks i see, the nvidia gpus seem to have better performance. I know that the ati drivers not perfect but does that say nvidia's drivers are? I sorta believe that nvidia's SP'S are faster than ATi's but still, 320 vs. 112.. somebody explain that to me nah.. my head kinda hard right now..lol

Spazosaurus · « **Reply #15 on:** February 24, 2008, 01:09:07 PM »

When ATI quotes a number for no of stream processors, its actually a lot less than that due to the way they count them. I cant remember the exact details but they measure theirs different than nvidia does.

. In its GeForce 8800 GTX incarnation, the G80 has 128 scalar stream processors running at 1.35GHz. The R600 is more parallel and runs at lower frequencies; AMD counts 320 stream processors running at 742MHz on the Radeon HD 2900 XT.

Nvidia has cited a peak FLOPS capacity for the GeForce 8800 GTX of 518.4 GFLOPS. The G80 can co-issue one MAD and one MUL instruction per clock to each of its 128 scalar SPs. That's three operations (multiply-add and multiply) per cycle at 1.35GHz, or 518.4 GFLOPS. However, the guys at B3D have shown that that extra MUL is not always available, which makes counting it questionable. If you simply count the MAD, you get a peak of 345.6 GFLOPS for G80.

By comparison, the R600's 320 stream processors running at 742MHz give it a peak capacity of 475 GFLOPS. Mike Houston, the GPGPU guru from Stanford, told us he had achieved an observed compute throughput of 470 GFLOPS on R600 with "just a giant MAD kernel.

Nvidia's stream processors are capable of more work per clock in certain circumstances, and are clocked higher , almost twice as high as ATI's . So Nvidia's 128= ATI's 320.

ATI i think is being held back by driver issues and the currant implementation of DX10. ATI cards usually lag behind the currant generation of Nvidia cards till a few years down the line, when games use their full potential eg.
Radeon 8500 versus Geforce 3 , shader 1.4 versus 1.0 .

Not quite Trini yuh could do better than that. In essence yes the Nvidia based cards are quoted as having less 'Stream' processors and in effect it does have to do with how they are counted. It's really the core of the architecture that separates them. Nvidia has a non-unified architecture. Meaning they have physically seperate units to handle the different types of calculations as it were. There are shader units, vector units and some others that I too lazy to get into. Point is, Nvidia uses specialized units for the different effects whereas ATI took the unified approach, meaning their 320 unified shaders can do all operations thus you could have say 300 vertex shaders and 20 pixel shaders or any combination thereof. Also they mentioned that Nvidia shaders run @ 2x the speed of the core iteself generally.

This is an interesting point as ORIGINALLY VISTA and DX10 specified that the approach was to be unified as opposed to Nvidia's approach. MS later changed the spec to allow Nvidia cards classification of DX10 certified. Either way, the performance from both are quite good. Everyone seems to be knocking AMD's drivers but they really aren't that bad to begin with. First off Crossfire has been see to work a HELL of alot better and without as many bugs and delays as SLI (which is a shocker considering who's tech is older) and also Nvidia has the 'TWIMTBP' initiative which puts them in favourable positions with game developers (which is all fair, if you have to money then go ahead). So when comparing the two architectures one has to consider the implementation and optimization. All things considered equal, I would guess that both AMD and Nvidia cards would perform very similar without optimizations in the game engines. But that is a moot point as its all fair in love and war.

ok thanks w1ntry.. so it seems that ATi's stream processors work the way microsoft intended the technology to operate but nvidia just decided to do their own thing. Pfft, well i guess if every company did the same thing in the pc world, it would have been a bit boring...

hmm just noticing that this topic has turned into something quite informative.. learn something new in alot of the threads i read here..
