[BitsAndChips]390X ready for launch - AMD ironing out drivers - Computex launch

[Gikaseixas]

Im wondering if there will be any announcement today at AMD conference. It started right now, if anyone is interested:

Thanks for the link

maddie, what's with the gigantic advertiser "viglink" url?

The link is for the paper in the post. It works for me.

A New Perspective on Processing-in-memory Architecture Design

... you're derailing the thread with your biased opinion.

You misunderstand me. Not bias, I WANT to buy a 390x if it shapes up to perform like some the rumors suggest, but I also like buying some games on release day. It's not a bias, it's a concern, a valid one.

Also here for everyone that would not be able to see that Conference.

Performance/watt leadership sounds intriguing

 

[RussianSensation]

^ HBM 100% confirmed, which we pretty much knew. Now need details on how many R9 300 cards will have it.

Performance/watt leadership sounds intriguing

In fact, the top three slots of the Green500 were powered by three different accelerators with number one, L-CSC, being powered by AMD FirePro™ S9150 GPUs; number two, Suiren, powered by PEZY-SC many-core accelerators; and number three, TSUBAME-KFC, powered by NVIDIA K20x GPUs. Beyond these top three, the next 20 supercomputers were also accelerator-based.

L-CSC achieved the first position on the November 2014 Green500 List with an impressive 5.27 gigaflops per watt. This system used Intel Ivy Bridge CPUs, AMD FirePro GPUs, and an energy-efficient software design to achieve this feat.

I think, if you will think about it, and count that, lets say, 125W GPU from iMac provides around 3.5 TFlops of performance that is a lead in perf/watt. Despite even Maxwell, academic professors say that GCN is the most energy efficient architecture that has ever been on this planet, as of today. However there has to be few circumstances for it...

nooooo I'm too late

have to wait for Computex / E3 for R9 3XX talk

 

[Glo.]

So, next few weeks, as people on TT say.

Come on AMD! Its time now!

Positive that they're getting to finfet/HBM 2 in good time, but it doesn't precisely sell the 3xx series terribly well knowing there's something twice as good coming in not that long a time period.....

But isn't that always the case?

 

[Enigmoid]

Not with clock cap from BIOS. 5 Tflops is achieved by non-reference cards without BIOS cap.

http://www.tomshardware.com/reviews/nvidia-geforce-gtx-980-970-maxwell,3941-12.html. Check out the slides. They are deffinitely around 300W.

Of course, were talking about compute power consumption, not gaming. Also, with clock cap, it will never get to 5 Tflops 4-4.2 is more realistic. At least thats what my experience shows.

Tonga throttles like mad in the imac running compute too. Not sure if thats TDP related or cooling but it uses MUCH more power than the m290x.

But everyone on our forum knew that R9 300 series and Maxwell are a stop-gap generation between the massive breakthrough of 28nm GDDR5/HBM1 GPUs and 14nm/16nm and HBM2. I don't think this is surprising. We still have 15-18 months to go I bet before we see powerful 14nm/16nm GPUs. I don't see them launching until September 2016 at the earliest to be honest. Remember not everyone wants to wait and there are plenty of gamers on older generations that will upgrade to Maxwell/R9 300 series to play many of 2015 titles. We have GTA V, TW3, Batman AK, Project CARS, Starwars Battlefront, Just Cause 3, etc. Lots of highly anticipated games that some gamers definitely won't wait 18-24 months for to upgrade for.

You don't honestly expect GP200 to replace GM200 in just 12 months from now? NV tends to have a 2-year-gap between its flagships. Since GM200 6GB hasn't even launched, we shouldn't really expect Big Pascal until April 2017. That's 2 years from now. Most likely AMD/NV 1st wave of 14nm/16nm GPUs will be similar to 750/750Ti/970/980 which is bringing current gen flagships (R9 390X/GM200) to lower price levels, slightly faster performance (+15-30%) and lower power usage. I don't think we are going to see a card for $700 2X faster than a GM200 by Fall of 2016.

Tonga throttles like mad in the imac running compute too. Not sure if thats TDP related or cooling but it uses MUCH more power than the m290x.

That has little to do with perf/watt of Tonga but the fact that Apple shoved a 125W card inside a 100W chassis. If you put a dinky heatsink that can't dissipate 125W of power, you are going to get > 100*C. Under a proper heatsink, it wouldn't throttle or reach 108*C so then his point stands.

Thats not how it works. And it is quite a long time.

If it was the case, you still sit with a 286 and some EVGA(Not the company) graphics and still waiting.

 

[Glo.]

Its the cooling of the iMac. Its a piece of s***, that design in this field .

Another example is Mac Pro where D700 is 3.5 Tflops GPU and uses at max 129W of power.

Lets say, Apple uses Fiji, and squeezez it to the same power envelope and simply doubles the performance of the D700 letting it run on 850 MHz(4096 GCN cores). Getting 7 Tflops from around 125W is pretty amazing.

That is probabbly why GCN is called most power efficient architecture in the world.

Reopened - This will be a final warning to everyone who wants to derail the thread by talking about Project Cars or anything off topic. This is an R9 300 series rumor thread. Create a new thread topic if you want to discuss Gameworks or Project cars etc.

Since GM200 6GB hasn't even launched, we shouldn't really expect Big Pascal until April 2017.

If anything, Big Pascal should be the first card released. Considering nVidia had to dump their DP-friendly Big Maxwell 20 design, I'm sure they will focus on getting a card to replace the (real) DP-friendly Titan (which is over 2 years old already) and Tesla first. When that will be in 2016, I have no idea.

As far as I can tell, nVidia is not going to release a SS 16FF Maxwell. It seems that the 980 Ti and 960 Ti are it until Pascal arrives. AMD will have HBM all by themselves until then.

Pascal is a big uarch leap, with HBM2 and on a new unproven node. Pretty risky to make that transition with Big Pascal, don't you think?

Post edited.
Not sure why you are ranting. Its up to people to trust what I post or not. I already said I can`t post what the guy gave me.

The HP Envy Pheonix desktop have either R9 380 or GTX 980 as GPU choice. The price starts at $899. For a full desktop with water cooling. You don`t have to be a genious to understand that the R9 380 won`t cost that much and it will be cheaper than GTX 980.

But fine, I`ll not post anything more then if I don`t have anything to back it up

Soooo.....

The. R9 380 OEM in the HP Envy has been confirmed to be ....

An R9 285.

"HP is already confirmed to be shipping PCs with these new cards, and we expect other OEMs to ramp up as well as they launch their back-to-school season computers."

 

[TechyGeek]

Hmmm here's one burning question I really need answer to:

Would a pair of 390x's bottleneck 4790k at 4.8ish in DX12 games?

Or for that matter, what would be bottleneck for these cards?

PCIe 3.0 x8 per card?

or 4790k at 4.8ish?

 

[Elfear]

Does this slide look like a disappointment in the making to anyone else? If the 300 series was really gaining the architectural improvements claimed earlier in this thread (i.e. > Maxwell performance/watt), then wouldn't AMD be pimping that pretty hard in their slide for 2015? The bullet for 2x efficiency being in 2016 makes me leery.
