GTX 1070 specs and the reason that nvidia didn't unveil it!

[lukart]

let's pray hard that the 1070 will not suffer the same fate that the 970 has gone through... Despite the 970's 0.5GB VRAM being a reserve space, it still win 1080p benches across all kind of games being thrown at it, with some potential in 1440p.

Being crippled 970 in the memory, that didnt stop from being the most popular nvidia has right now...

It appears that the GTX 1070 is even funnier than its name. Nvidia did not unveil the full spec of its GTX1070 because ... lol guess what:

GTX 1070 has 1920 SP !
Clocks : 1530MHz, boost 1670MHz .
Ingame it can boost upto 1800Mhz

I just wanted to share this because Its so freaking funny that both of Nvidia cards has 1080p in its name. and believe it or not this is why they didn't want to unveil everything about the GTX1070.

Just to be clear this is not 100% sure!

*source: ... umm... I promised to not tell.

I did some math myself and came up with the exact same SP count as the possible specs for the 1070. I am not sure why you're making it sounds so surprising. Maybe I am interpreting you wrong and the 1920x1080 thing is just what you are reacting like this for and not that you think it's a low SP count and shitty.

Based off the 6.5TFlops announced by NVidia and considering where the 1080's clocks are this is very feasible. I hope to see a higher SP count though because then the core clock will be lower and an overclock on it will be even more impactful.

Just unsub it if you don't like it and let people discuss what they want in peace.

Regrettably, at this moment, no I can't get you a source to OneMoar's claim. However, it was pretty common knowledge that the 660 was partitioned into 1.5GB memory portions.

This is why the 3GB version was preferred, despite nothing using 3GB back then, because the memory was symmetrical.

On the 2GB versions though (with a 1.5GB segment and a .5GB segment), no one really noticed, because games were not using all that VRAM anyway.

Asymmetric memory like the 660/660ti is very different from what was done o the 970.

but the end result is the same special steps need to be taken to get the most out of it

 

[EarthDog]

What special steps are taken to get the most out of either card??

 

[newtekie1]

Not really.

 

[OneMoar]

Not really.

yea really have a look at the driver change logs and game patch notes for that era
you would be surprised the amount of effort that goes into optimizing a game for a single card especially when gpu vendors do things like monkey around with memory access

 

[EarthDog]

So, nothing the end user needs to do. Gotcha. NVIDIA did have a driver update which was said to help with that memory management. As an end user though, we did nothing but enjoy it in most cases.

Exactly I mainly meant that it so funny. The fact that they did not unveil the GTX1070 spec because of the 1920x1080p. Its just thier marketing. It is so funny that one of thier cards is called 1080 and the other one has 1920 SP.

And about the 970 the reason they did that was to make sure no one will get more performance out of the 970 more than they already planned. They were worried about ppl overclocking it.
It is indeed so ridiculous the fact they were selling the same physical chip and they decided the lower SP count is not enough to limit the 970 performance, so in order to make sure that it will not out perform what they have planned already, they did that with the 970.

With the GTX 1070 .. we will see anyway. However for sure that right now they are more careful on how they limit the chip.

As I said before, if it would have just 1GB slow memory of the 8GB total, who cares!
And as @Maban said:

better than 980 for a little less.

And as @Maban said:

Well , think about it like this then . Imagine buying an 8GB of RAM to upgrade your system, and someone sold you a memory (saying that its 8GB RAM) and later you discovered that it was only 7GB of it is working properly.

would you be happy about that ?

Maybe not, but I don't know any game yet that uses 8GB of vram at 1080p, I will buy a GTX1070 and use it for 1080p and even 7GB vram is more than enough for a very long time!

I did not buy a GTX970 because of the memory issue, since it only had 3.5GB fast vram and there are games now reaching over 3.5GB vram usage.

Unless I'm mistaken, hasn't the memory subsystem of the 1070 been known for a while? Same 256bit bus of 1080, just lacks the GDDR5X?

 

[agent_x007]

1920 CC's is exacly 3/4 of total from GTX 1080 (2560 CC), so the number does make sense.
Only requirement for this is that we must assume that total number of SMM's can be devided by at least "4" (ie. GTX 1080 has 4, 8, 12, 16, 20, 24, 32, 36, 40, etc. SMM's).

So I guess "consumer grade" GP100 (that 1070's successor should have), will get 2560 CC's ?

I think 1070 will have 256-bit bus with GDDR5.
GDDR5 vs. GDDR5X should make enough difference, to justify not cutting memory bus width (in theory).

Memory width vs. Bandwidth comparison :
320GB/s (GTX 1080) vs. 256GB/s (GTX 1070 256bit GDDR5) vs. 224GB/s + 32GB/s (GTX 1070 224bit + 32bit GDDR5).

EDIT :
The extremely NOT likely scenario (GTX 1070 with 10GHz GD5X) :
224bit + 32bit 10GHz GDDR5X = 280GB/s + 40GB/s

In my case it does not matter if it would have 1GB of crippled memory since I only play at 1080p.
People having a GTX1070 (sli) and a 4K monitor, well that's a different story.

The GTX1070 is exactly the same chip as the GTX1080. GDDR5X is compatible with GDDR5. From what I understood, a lil tweaking is needed to be done to the memory controller .

What made all the drama about the gtx 970 was the fact that they were advertising the card as if it was exactly the same spec as 980 just lower SP ( or CC) count. where in fact it was NOT just lower SP count it was lower memory lower L2 cache and so on.

If they just announced the card the same way as it really was no one would be cheated no one would feel annoyed

I do agree with that, when that came out, the GTX970 was being sold as 3.5 + 0.5GB vram in the specs in my country.

That's slightly different. I bought GTX 970 (that's my second 970 btw) because of it's performance, not because of it's official specifications. After we figured out about 512MB of "slow" memory, this card did not became any slower or any worse. In my Steam library there are only two games that happily take up to 4GB of VRAM (Arma 3 and GTA 5) and guess what? I can't feel any difference when some textures are loaded into "slow" partition - games work buttery smooth.
Nvidia should have been more detail with GTX 970 specs, although i don't see this such a big issue as some people made it look.

I think you mean the 1070 is compatible with GDDR5 and GDDR5X.

 

[CAPSLOCKSTUCK]

i cant wait to buy a cheap 970....should be plenty around anyway.

They're still around $500 new here.

The prices went down from 355 last week to 335 Euros now in my country, but I'm not buying it
