AMD Scorpius desktop platfrom and 32 nm Zambezi in 2011

[informal]

I just can't understand why they're keeping the K10 AND giving it the new socket, if it already works as it is in AM3r2?

^^Probably because the new Llano MPU will require more pins due to integrated GPU so the AM3r2 socket won't be enough.

[saaya]

Games don't, but GPGPU do.

I've had a number of requests for a CUDA version of the Pi-program in my siggy. Poor DP-FP is one of the reasons why I can't do it right now.

so instead of improving graphics performance on their new gpus, you WANT nvidia and ati to INSTEAD use transistors and time to improve the DPFP performance so we can run superpi on a gpu... :P

sounds to me like am3 is fine for non igp cpus, but for igp cpus they need a new/revised socket

Obviously not for benchmarks...

But there's about a billion useful things out there that require DP-FP and are highly parallelizable.

Seeing as how nvidia has been pushing for GPGPU for a while now... it will probably help them out a lot if they improved their DP-FP.

I'm guessing AM3r2 is AM3 with HyperTransport 3.1 (6.4 GT/s). That's one reason I feel why it's AM3r2, and not "AM4". So I'm also guessing it's going to be pin-compatible.

ok, thats a bold claim there, and its based on speculation... and even if thats true, and there IS a lot of demand, then it doesnt mean its easily portable to gpu, and even IF its easily portable, it still doesnt mean its going to happen...

building a product for applications that dont exist is ridiculous... im surprised nvidia keeps blowing money on it before there is a propper infra structure... thats not how it works...

you either pick one or several existing tools and then accelerate your hardware for it, or you cooperate with the devs and build the infra structure together, they do the software you do the hardware, or you do both, software and hardware.

nvidia just creates the hardware and then waits for the software to come out of nowhere... except for some few tidbits of code they wrote for devs and then lets them use it for video transcoding and image processing...

Yeah I'm sure Llano needs more pins, but that doesn't explain why they're putting old K10 cores in AM3r2 packages when they have a whole new lineup coming, which the text says.
We're talking about different things here.

Besides, that pic doesn't say that Llano uses AM3r2, tho I hope it does.

just name at least 3 which comes to your mind... then speak...

Finite Element Analysis
Matrix Inversion
Matrix Multiplication
Fluid Dynamics Simulations
Thermal Dynamics Simulations
Fractals
High precision Mandelbrot
High precision Arithmetic
Fourier Analysis
Fourier Transform
Signal Processing (not sure if this requires DP though)
Discrete Event Simulations

You just named some buzzwords thats all, matrix mul can be anything int, sp, dp, so now name actual apps which uses them and you use them daily...

fermi has a peak of 768DP GFLOPS. thats 8x faster!

The market for GPGPU probably won't be on the consumer side as much as the industrial side. You won't believe how much companies are willing to pay to make their simulations go 10x faster. Especially when there's money to be made...

Woah... that's serious...

[blaH]

heh no argue there, but simply from my as consumer perspective DP is nearly useless

[haylui]

I want Thuban comes out Q1 2010...would like to double the core counts for my Phenom II X3 720BE (Phenom II X6 xxxBE??)

[Jamesrt2004]

I thought there claiming only 2.5 better though

[Chumbucket843]

fermi whitepaper says around 4x faster effective. it really depends on what you are doing though. the power point slides arent really an effective way to combat 58xx.

[ajaidev]

Yep that is quite fast but the 5870 X2 is suppose to have around 1088 Gigaflops and if we look at a cheaper alternative the 5850 x2 may have around 838 Gigaflops. Now those value seem unrivaled by GF100/GT300 and only a GX2 version which can score around 15xx DP points can kill them. In terms of cost i think 5850 x2 will rival GT300/GF100.

BTW For people who are interested 5870 has 544DP and 5850 has 419DP

Barcelona (city), Deneb (star), Thuban (star), Zambezi (city)...
Uh-oh. Ominous.

And I wonder if AM3 rev2 will be a PGA or LGA...
And why they didn't go LGA with AM2.
*shrug*

But I hereby demand they go 192bit memory on Bulldozer - I want my 6 DIMM slots on desktop boards.

APU, as in "accelerated processing unit". GPU-on-CPU. Few Bulldozer cores with a low end GPU on-die.

Zambezi is a river. Borders Zambia and Zimbabwe. In Africa.

Welcome to XS boards bro...

But this^ thread is old, you necro'd it back to life as most these posts are 7-8 months old.

[Florinmocanu]

Well, the subject is pretty interesting. Would be nice to hear more things about Scorpius/Zambezi.

saaya, there is a lot of demand in HPC clusters for GPGPU computing.
and re:applications, they are always customized for these jobs, climate modeling, oil exploration, etc.

The Nebulae system which uses 4,640 Tesla chips, consumes about 2.55 megawatts compared to about 7 MW for Jaguar.

eetimes

there is also one other chinese supercomputer that uses ati radeons:

and 5120 AMD RV770 GPUs [2560 ATI Radeon HD 4870 X2 2GB cards]. Together, 6144 Intel CPUs and 2560 AMD GPUs reach a theoretical speed of 1.206 PFLOPS.

hardware is always ahead of software, as history shows.
i think youre just off your game today. coffee?

that last roadmap doesnt seem very legit at all

i just want me a nice 8 core bulldozer for my rendering and i will be a happy puppy

Bulldozer with 8 cores/16 threads, it'd be great considering how Intel is doing good with their HT

Bulldozer for desktop is 8core/8thread chip,no SMT in version 1.
