AMD: Volcanic Islands R1100/1200 (8***/9*** series) Speculation/ Rumour Thread

Sweet. So the average and minimum for the Titan are the same 15.1 fps. That is one hell of a consistent (if low) benchmark run! Quite a neat trick getting the maximum that high also. I was figuring on....maybe 15.1 fps ?

 

And under FXAA the average frame rate is lower than the minimum.

I think we can conclude it is faked then.

 

I was do the same comment on an other forum about this.. Thoses information are completely contradict the AMD presentation..

The memory bandwith: 288GB/s is the same of the 7970 (ghz), what interest to pull a 512bit MC for get the same bandwith and it dont match the 300GB/s of their slide.

No "turbo" or higher turbo clock: if it can only lower clock, its more like the 6000 series era..

Core clock speed, dont match the presentation slide " > of 5Tflops", triangle rates.

fake or not?

 

Graphics score: 10882, almost 1000 more than titan. 9238 total score.

If this was true, why in AMD slide it only showed near 8000 for R9-290X?.

 

Clocks are lower than expected... maybe they will be higher with retail drivers?

 

They have to be to match the figures AMD provided.

 

I dont know if it is true or not.. ( i mostly think it is a fake, could be overclocked etc ).. But i will not too much base myself on what we have seen on the presentation about performance.. They was really not give any real precise numbers.. only some hint ( higher of, more of ... )

 

Was the dual bios rumour confirmed? That's the only way this latest round of "benchmarks" makes any kind of sense I think.

 

Memory reported = 3.072 MB. Doesn't R9 290X ship with 4 GB?

 

GTX Titan show 3gb in 3dmark too.

 

second with 800mhz

maybe Alienware testing their new machines...

 

32bit Vs. 64bit related problem

 

Corrected the GPU clock to 1050 MHz. The ES card the benches were run on has two BIOSes, one with 800/1125 and the other with 1050/1125. The benches were run at 1050/1125

So, with 1050MHz GPU clock, the hint at "over 5TFLOPs" most probably leads to 2560 ALUs (40 CUs) and 4200M primitives/sec.

 

if it's true Titan looks to stay on top, and r9 290x will fight only vs gtx 780 and no chance vs probable gtx 785/gtx Titan ultra...What you think ?

 

Or the R9-290 has 40 CUs at slightly below 1 GHz and the 290X has the rumored 44 CUs@1050Mhz resulting in 5.91 TFlop/s. Would still be above 5 TFlop/s. They had to use the 6.2 billion transistors for something.

Moar L2 cache!

TRUE AUDIO!?!?

 

Um, sideport != CF bridge. I would be very surprised if the CF bridge interface was even 2x PCI-e. Its been a while since I've looked at it, but I not sure it has enough traces to do anything above 1x PCI-e which would put it the bridge at 1GB/s.
