AMD also rumored to be using GDDR5X on its next-gen 14nm GPUs

[Mr_Troll]

When we heard whispers of Nvidia using GDDR5X memory, it made sense. HBM2 is going to be sparse, and with AMD reportedly having 'priority access' to HBM2, the use of GDDR5X is going to come in handy, big time. Not only is NVIDIA said to be set to reveal GDDR5X-based video cards, but AMD will, too.

 

 

 

According to a new presentation, GDDR5X is going to provide twice the data rate per memory access. We're going to see it jump from the current 32B data per memory access, to 64B data per memory access. GDDR5 has hit a ceiling at around 7Gbps, but GDDR5X is going to have a much higher I/O rates of around 10-12Gbps.

 

It looks as though GDDR5X is going to be used well into 2018, while GDDR5 will most likely be kept for lower-end cards. I think we're going to see $50 - $300 cards with GDDR5, $300 - $500 cards (and possibly higher) with GDDR5X, and $500+ left for the higher-end HBM2 technology. The use of GDDR5X by AMD and NVIDIA is going to save much more money on R&D, because instead of moving over their entire next-gen GPU product lines, they can continue to use GDDR5X, which is not all that different to the current GDDR5 technology.

 

Not quite sure if this was posted or not. Please close this if it is  repost. Surprised how micron made DDR5 memory last that long.

Makes sense. They'll probably use HBM only on high end GPUs due to higher production cost.

[don_svetlio]

and in reality it's the high end users that will make best use of the insane bandwidth it can provide

Awww, I was so excited for the GT 1040 with 32GB of HBM2

[bogus]

I'm afraid GDDR5X may be an excuse for re-releasing previously released GPUs.

[Bob Jim]

IMO it should be something like 950, 960, 970 equivalents get GDDR5X, 980, 980Ti equivalents get HBM2, and sub 950 equivalents get GDDR5.

Like a 960 that's actually go enough bandwidth?

[don_svetlio]

That's probably how it's going to be.

[Alurit]

I wonder how much power gddr5x eats up, cause ms decided to put 1gb of gddr5 into the surfacebook cause the vram consumed more power than the custom maxwell gpu.

I actually wouldn't care if $GPUCompanyA re-releases/re-freshes/re-hashes the previous gen hardware with a slight stat boost in some areas, as long as it's competitive with $GPUComapnyN's offerings at each price point, and is better than previous generation's hardware at the price point.

 

It doesn't matter what the specs are, just how it performs compared to the competition...... right?

[don_svetlio]

lmao, that card is pretty pointless as it currently stands. Why 2GB? WHYYY?

 

seems like that's how it'll be, would make sense too

 

not a bad thing, the extra bandwidth will help a lot. Take the 960 for example, it's pretty choked.

My favourite part is that the 2GB 960 is going to be removed entirely - leaving a 4GB card with 128-bit bus. Pitiful

[don_svetlio]

even if they only leave the 4GB model and made it a 256 bit bus, it'd probably still have the crap beaten out of it by the 380 tbh. I wonder if there's a bus width they could implement between 128 and 256, then again, probably not. 256Bit would probably be a bit overkill seeing as it's just above entry level. The 970 has a 256 Bit bus and that continues up to the 980, where the 980Ti and the TitanX have 384 Bit Buses. If they could implement a step inbetween then the 960 might become a bit more relevant. But right now that 4GB model is about as pointless as the 4GB 750Ti's that are floating around. Like seriously, who needs 4GB of memory on a 750Ti?

Asus do - they made the 4GB 750 Ti

As for bus - 192-bit 3GB 960 Ti is what we need.

4GB 750Tis are for prebuilt marketing and cheapskate bragging rights.

It's retail, not OEM

[don_svetlio]

ASUS and Gigabyte.

 

Shit, i forgot about 192 bit. I don't think a 960Ti is in order, but if the 960 was a 192 Bit 4GB card it would be a good step inbetween the 950 and the 970. Personally, I don't feel that the 950 having 2GB of VRAM is enough. I think the 2GB card should be a 940 or something and the 950 should have 3GB. It'd make it a more even slope. You could use 3GB on a 128 Bit bus, just about, but I've seen games tear through 2GB of VRAM on my 970 at 1080p, and if the 950 is meant to be the entry level king it needs a bit more memory than it already has.

 

4GB 750Ti's shouldn't exist. The 2GB model was more than enough for any 1080P needs that a person using a 750Ti was gonna be gaming with.

I shred through all 3GB on my 280 at 1080p on several occasions - 4GB is what you want for 1080p.

[don_svetlio]

Also - when the 380X comes out the 960 will be completely obsolete. 960 Ti is a must else the 380X will reign supreme as king of the price:performance segment with 384-bit 3/6GB versions

I believe the 380x will be 256-bit much like the 380. Same architecture.

Nope, 384-bit with 3GB and 6GB configs - according to leaks from a few months ago IIRC

EDIT: 380 is Tonga Pro

380X is Tonga XT

Any clue when 380X comes out?

Likely either November/December

ooooh tres interessant - let the battles commence I say

This one states 256:

The last one:

"The AMD Radeon R9 380X graphics adapters will carry 4GB of GDDR5 memory, which indicates a 256-bit memory bus, not a 384-bit memory interface, as expected by several unofficial sources. Usage of 256-bit memory interface should simplify printed-circuit boards of the graphics cards and make them cheaper. As a result, makers of add-in-boards will be more flexible in terms of final pricing."

I guess we can only wait and see - I'm still expecting 384-bit since it makes more sense

[don_svetlio]

or you could get a 390 and crush everything with 8GB of memory.

 

If only the 390 came with EVGA's sexy sexy ACX cooler

This is an absolute beast of a card...and it comes with a BACKPLATE.

If I had the money(which I could have had...if I found out earlier, my high school would reward those who get >9.5 out of 10 at the big exam) I'd be all over it.

Still, I got an MSI 380 4g and it's also fast and sexy.
