Nvidia's GTX Titan class GPUs always come with huge price tags and the Pascal GTX Titan X is no different, costing $1200 in the US. GTX Titan series GPUs have never been about Value for money, but they have always resulted in lower end GTX variants like the GTX 780Ti or GTX 980Ti that provide gamers with relatively good value for money.  

Ever since the GTX Titan X launched the big question on consumers lips was "where is the GTX 1080Ti", knowing that a more affordable variant is in the works. 

Now, a Nvidia GPU that is thought to be the GTX 1080 Ti has been found in an Indian shipping manifest, with the GPU sporting 10GB of VRAM and a 384-bit memory bus, suggesting that this GPU is more powerful than Nvidia's GTX 1080.  

 

   

When looking at Nvidia's previous GTX Titan GPUs one trend is clear, that the lower priced Ti variant of every Titan GPU has half of the VRAM of its Titan equivalent. The GTX 780Ti had 3GB of VRAM compared to the 6GB on the Titan Black and the GTX 980Ti had 6GB compared to the Original GTX Titan X's 12GB. 

Today's Titan has 12GB of GDDR5X VRAM and simply halving it would result in a GTX 1080 Ti that had 6GB of VRAM, something that Nvidia would simply not release given the fact that their GTX 1080 has 8GB of VRAM. With the GTX Titan series always having a VRAM capacity lead over their desktop counterparts we expect the GTX 1080Ti to have either 10GB of GDDR5X VRAM, using a cut-down memory bus to allow for the GPUs lower VRAM capacity. 

In order for the GTX 1080Ti to have less VRAM than the GTX Titan X but more than the 1080 Nvidia will need to use a smaller memory bus size,  changing their 384-bit memory bus to a 320-bit memory bus, allowing Nvidia to use fewer VRAM chips and create a hypothetical 10GB GTX 1080Ti. 

This decrease in memory bus size will also result in a decrease in overall memory bandwidth, lowering the total memory bandwidth from 480GB/s down to 400GB/s.

Right now we have no idea if or when Nvidia plan on releasing their GTX 1080 Ti GPU, though we do expect Nvidia to release something in response to AMD's upcoming Vega powered GPUs in early 2017.

Hmm. I'm still a bit paranoid about Nvidia atm tbh, especially after the lame 1050 and 1050ti. What I mean is that this time around Nvidia have made sure to leave a chasm sized gap between their cards.

The Titan XP is 12gb and usually we would expect most of that (VRAM) and the same performance however this time around I have a feeling they are not going to usurp their own Titan XP (nor mug off the people who paid £1300 for one, that would make a change then !) and the 1080ti will probably perform between a 1080 and a TXP with absolutely no way of making up that deficit by means of overclocking.

For example, the 970 was easy to overclock to stock 980 etc. I have a feeling that this TI won't be like the ones from the past.

Not that slower than a TXP is a problem but the TXP IMO is just enough for smooth 60 FPS 4K.Quote

Not everyone expected the non-reference 980ti's to be able to easily surpass a Titan X, but they did. I don't see how they are going to be able to beat a Titan XP with the 1080ti this time around as overclocking Pascal is not as good as Maxwell was.Quote

According to some "leaked" manifesto details this will be coming in around the $1000 mark so upwards of £800.

Big no go from me, I'd rather keep hold of my classy and wait for the next iteration of cards.Quote

Makes sense with the amount of GPU memory.Quote
