HD7000 inside - Trinity rumors confirmed, GPU, speeds and more

That leaves the GPU. If you notice, the GPU is listed as HD7000, aka Graphics Core Next (GCN), aka Southern Islands. That means going from VLIW5 to scalar + VLIW4, whatever the code word for that is. In any case, going from 80 ‘old’ clusters (400 shaders) to 120 ‘new’ (480) clusters is where the majority of the 50% comes from. Throw in an updated memory controller, tighter integration between the sides, and you have not only more speed, but much more exploitable speed.

Census is that Trinity will be out same time as Llano was? Or after?

[~CS~]

Just because it's Hd7000,doesn't mean the architecture will be GCN,it could still be VLIW4,in the same manner as the current lineup HD6000,which consists of VLIW5 and VLIW4 GPUs.

It is vliw4, Mr Houston and then Mr Baumann confirmed.
I dunno why Charlie posted that it has 480 shaders... that would mean 6 VLIW5 SIMDs or 7.5 VLIW4 SIMDs, which isn't possible.
It is either 8 vliw4 SIMDs with the same clockspeeds, ~600mhz, or 7 vliw4 SIMDs @ ~700mhz.
I'm leaning towards the 8 SIMDs.

50% more gigaflops means about 50% more fps too right?

Only if you are comparing same architecture vs. same architecture.

true, which is why i said about.
if this new arch is similar to that of caymen, which per SP is quite close to barts (sadly caymen comes out worse in perf/SP on TPU), then i would think that overall its will be a slight increase in efficiency, at the cost of raw gflop numbers, meaning that in games trinity should be a serious killer. BD based cpu that hopefully clocks very well and delivers much better IPC than llano, and lots of extra gaming power, and hopefully a better turbo setup than llano, i honestly might have to buy one as a laptop and just give up on desktop gaming for a few years (until nextgen consoles finally bring a new level of quality)

also this is for 28nm if memory serves me right, which should offer a pretty cool power consumption reduction over upcoming 32nm BD and even llano
im liking how AMD is using both steps to deliver new parts since it keeps things fresh rather than seeing one massive jump every 2 years, we see a noticeable and subtle jump every year.

Trinity is 32nm as the picture says. You must be thinking of Wichita which is a 28nm Bobcat APU with up to four cores and possibly a few more shaders.

[qcmadness]

I am more interested in the Bulldozer cores.

[Dimitriman]

Dude that's soooo yesterday's news...

[FlanK3r]

50% more gigaflops means about 50% more fps too right?

I think, its only theoretical throughput in GB/s

[Alex-Ro]

When is this going to land?Hopefully not in JULY 2012...

sad i didnt even read the title of the slide, lol.

Orochi is up to 35% faster than current Opterons? With 33% more cores that doesn't sound to promising.

[Lanek]

Hard to say, i don't know why they have choose the term of server .. a server performance increase depend of many thing... All i know is all Cray have moved to Orochi .

Anyway, i think like many, they want to traduct this to Bulldozer performance for desktop .. game, sadly if they are based on the same architecture, the cpu are absolutely not the same in term of clock speed and functions.

Orochi clocks were originally thought to be in the 2.6-2.8Ghz (base) area and were compared to 2.3Ghz top MC system back in 2010. This resulted to around 50% integer and >60% fp throughput. Now, 12C MC has 2.5Ghz clock speed and Interlagos is launching at 2.3Ghz (base) clock for top model. 8% more clock speed for MC and 21% less clockspeed for Interlagos = up to 35% throughput. Int_rate should be a bit lower than 35% and fp_rate somewhat higher than 40%. Average 35%.

You forgot to take memory bandwidth into account, many server applications rely on heavy memory workload, if RAM spec doesn't increase those part couldn't have additional performance gain.

[informal]

Mem BW is ~50% higher on Interlagos vs MC. This didn't change since it's not a function of CPU base clock speed but of memory controller and DDR3 speed.

XDR 2

[Alex-Ro]

XDR2 is that memory that works at 8000 mhz?If so,that's damn great news.This winter is gonna be awesome

[Motiv]

This mixture of tech is always confusing me now. Are all these cards 28nm, but the 79xx range based on new tech only (the others based on 69xx tech). Sorry, I don't know all the words for the card names anymore..age is getting to me

[n!Cola]

I hope xdr2 will not rise the price very much..
xdr2 can hit up to 12.8Gbps.

[Mats]

This mixture of tech is always confusing me now.

Just like Zambezi and Llano.

[xBanzai89]

Lol I guess I should upgrade my 4770 if even the low end 7570 will out do that old card.

[Manicdan]

this better bring prices down for GPUs
those 76xxs should be worth <100$, but today they are close to a 68xx selling for almost double that
