Updated 2nd Time: Maxwell 800 series GPUs will be "quiet" powerful.

[SinOfLiberty]

Cyberland PC reports that the GTX 800 series are going to be significantly more powerful than the GTX 700 series but their pricing would be lower than when the top of the line cards of the GTX 700 series became available..

Update: I got in touch with the source, here is the interesting tidbit:

The flagship sample has 384 tmus as well as 512 bit interface.

I think this is an engineering sample, nevertheless, great news!!

Update 2: I have got an interesting info from a convo about an ARM core count and a gpu called GTX 880 Enterprise Edition

GTX 880 Enterprise edition could feature full 8 ARM v8 cores, possibly sold for hpcs.

Note: this is from a different source. I am not sure how good the info is. But ARM cores are definitely playing a role in 2nd gen Maxwell, from what I have gathered.

PS: I stayed up the whole night for this info. Now it is 7:40 am, and I should have a busy day.


In the interest of time, I was previewed a Crysis 3 DEMO mission running on a single GPU.

Here is what mission I am talking about:
That is where you proceed to destroy reactors in different places while you are bombarded by an alien weapons. Now, the mission ran on max settings, including 8mxaa in 4Kres(3,840x2,160) with a frame meter in the right corner. Now, why am I posting this? Well, throughout the mission, the frame rates have never dropped below 60 fps, even in the most intense environments. I think, this mission has been picked on purpose as it is considered to be one of the most hardware resource heavy in the game. What also was on screen is a gpu score meter, where a different set of scores was displayed by a gou after each 5-8 minutes of a game run. This could be one of beta driver builds, where GPU reports a score on how well it runs an application.

Now, take it if you like. I don't know how creditable this source is. But a horsepower of this gpu definitely goes out of hand. This cant be GM204, I can confirm, based off what is gathered so far.


"GTX Blue" F****g "Moon"

The perf/$ should be there thou.

PS: very bad internet here.

Update 3: Ready?@

Kepler will stay with us for a bit longer.

I am off to watch Kardashan`s wedding.

So quietly powerful, we will not hear from them until 2015 ...

I still have 1920x1080 monitor.

its ok Pat, at this point in time I'm still using a 1680*1050 monitor...and my new computer has a PNY GTX 770 OC2 4GB...

hahaha, you will be surprised

[SinOfLiberty]

Pedant One, nice that you post again.

too busy with new stuff now ?!

[GoldenTiger]

Can't wait, have my 4k monitor in hand and a closed loop kit w/ Kraken G10 coming in for my current GTX 780, which I will hopefully figure a way to move to the GTX 880 once it arrives . "Quite powerful and cheaper than the GTX 700 series launch" sounds good to me.

PedantOne is around, something must be cooking .

I highly doubt about cheaper than 780 Ti, this is when talking about 880. But it is possible. Although I would aim at ~650$. On performance info, I completely agree.

NV will launch 1st, followed by AMD.

All I know is I have to replace my 570 as It does not do the best job in 4K BF3(note: I have upscaled my monitor`s native res, 1200p to 4K).

Get ready, great times ahead !!

Interesting indeed, this database...

"SOCKET BASE, S-BGA-145-080-GK104/GM204"

Looks like they've been shipping around test boards for months now, maybe Maxwell is going to come in July like some of us speculated originally . Seeing some signs such as GTX 780/ti prices going on pretty large sales + low/no stock suddenly, just like before the 780 came to the 680... maybe we'll be lucky and the mountings will even be the same for things like the Kraken G10. The latest entry says something more complete about what appears to be a board coming from the US, perhaps to a manufacturer overseas to get ready for production...?

Another interesting snippet: "PG401-A00 SKU0000 GM204 256BIT 128M COMPUTER GRAPHICS CARDS P NO.699-1G401-0000-000" which matches previous references to GM204 test boards in there.

[SinOfLiberty]

These might be mobile cards btw.

I am pretty sure there will be a mix of 2xx GMs in 800 series.

[boxleitnerb]

hahaha, you will be surprised

My guess:

GTX 780 Ti + 30%, release date October/November 2014. Close?

It's almost the exact same situation Nvidia had with the 680 vs the 580, the 580 maxed the process but the 680 was much faster. The only reason the 680 wasn't cheaper than the 580 was because the 7970 didn't set the world on fire on launch which allowed nvidia to raise the price, as the 680 yielded a lot better than the 480 did.

And how many months of making Tesla then Titan and then 780's before Nvidia could release the 780Ti and the Titan Black?

So it might not be cheaper, but it will be cheaper to make. Retail price will depend on AMD.

In the post you quoted, I wrote NV is launching first. So, my statement hold true.

PS: 680 was not much faster. Compared to 580 OCed, 680 was hardly a next gen card. Unless you had to take TDP into an account.

[boxleitnerb]

That's a rather safe bet boxleitnerb

Too conservative? The 750 Ti is about 25% faster than the 650 Ti. Yes, it consumes less power, but it also has a bigger die size. I can't see Nvidia going all in with GM204, that's what GM200 is for.
As for the release date, didn't GM204 tape out only about 1-2 months ago?

Too conservative, check my theory in this link made before the 750ti had launched... Turned out to be very accurate. The cache makes a huge difference too. Posted it on Feb 15th .

The tape out thing was an unsourced forum rumor by the way. Could be true but don't believe so.

[tajoh111]

Sounds like they are going to have gm104 = gtx 880 again. Booo, I hated this. An x80 should not be under 300mm2. Anyways, who ever comes out first, has the potential do do alot of damage against themselves by pricing too high or underperforming. Nvidia would be wise to not repeat the mistakes of the 7970 launch and to move the performance per dollar ahead significantly.

If it is gm104 = gtx 880, hopefully it is r9 x90 series like sizing. Either way, the smart thing to do is to make the decision after both companies have their cards on the table.

I could see a 4-5 GPC (probably 4) coming out as the GM204 flagship part which would still make for an incredibly fast card (4 GPC = 2560 Maxwell shader units). Check out the thread I linked above for more thoughts, but I definitely think even with a GM204 we'll be very very happy once it's available .

At this point GPUs are largely bandwidth-bound, and GDDR5 has exhausted its potential. This is one of the reasons AMD went with a 512-bit bus (and one of the reasons it's often faster, too).

Since Nvidia likely won't offer 512-bit bus on a x04 GPU, and GDDR6 doesn't appear to be ready, I wouldn't recommend getting your hopes up about major speed up over GTX 780 Ti.

You seem to be stuck on the concept of bus width. The 2mb of L2 cache used in Maxwell blocks helps bandwidth efficiency and reduces fetch needs greatly over the Kepler generation. The architectural improvements will add up to a lot. It would take a major flub for a GM204 or GM200 Maxwell card to disappoint.

[Lanek]

Actually whatever is the cache size, it need the bus controller width for work plenty.. its good to have 2mb of cache vs 1 one on a 256bit bus, its even better to have a 2mb of cache with a 384bit bus ( let alone a 512bit bus ).. Then it is even more important to have a cache and memory controller coherency.. What you say for a 256bit bus and a big cache is too valid for a bigger 512bit bus and a bigger cache .. When you can increase bandwith efficiency and reduce fetch with a bigger cache, it work too on a bigger bus memory controller . ( its working even better, i will take the example of the 290 where the cache size is certainly limit the 512bit bus ) ..

Anyway the question for 2015 is, will we see stacked DDR rame or not ? AMD have got is first prototype ready more of 4-6years ago..Nvidia is preparing it too.. im not sure we will see it for the next generation, but this could well change many thing on the side of memory bandwith.

[GoldenTiger]

Oh sure Lanek, but we're talking against an older architecture with a much smaller cache, in this scenario, in which case we may well see even a 256-bit bus provide plenty of bandwidth for a GM204 Maxwell card. That was really my point, of course if the same amount of cache is present a higher bus width will help .

I'm guessing we won't see the stacked memory until the very beginning of 2016 but who knows... little far out to speculate on too much for me. That said it promises a lot!

[boxleitnerb]

Your math is nice and all, but it won't happen that way. 20 nm isn't ready (capacity, Apple) and it is expensive. And Nvidia will not double performance if they don't need to. People bought the 680 that was only 30% faster than the 580. We call it "salami tactics": A little slice, another one, making money with each one instead of saturating the market only once with cards that are too fast. The times when a next gen card was more than 40-50% faster than its direct predecessor are gone for sure. Development has become too expensive for that.
