The name of the next generation of consumer focused Nvidia graphics cards seems to be anyone’s guess. Several hats have been thrown into the ring including Volta, Turing and even just the obvious GTX 11 series as people all over the globe speculate on the replacement for the monstrous 1080Ti. We’re going to take a look at the rumours to see which, if any, hold water.

Nvidia Volta

After the release of the Tesla V100 and then the Titan V, speculation was justifiably rampant that a consumer version of the cards would be arriving based on the Volta architecture at some point. However, the release date of the Titan V in December has seen six months of deafening silence from camp Nvidia, which has many people scratching their heads.

We would assume that the consumer cards would be based upon the Volta architecture as well, which has many people very excited as it’s been producing some outstanding results.

What is Nvidia Volta?

Volta is the name for the microarchitecture – a design which will be used as the basis for the next generation of consumer graphics cards (as well as the workstation and enterprise stuff).

The current generation, including the Titan Xp and GTX 1080-1050, are based on Pascal architecture. Prior to that, it was Maxwell.

Originally, the plan was to go to Volta after Maxwell, but for whatever reason Pascal has arrived in the interim.

Nvidia Turing

Turing is the current favourite to win this particular race, as some rumours have been circulating about a mid-June production for a post July release.

Reports suggest that Turing will be known as the GTX 11 series, and that the cards will step away from the conventional system of naming that the Nvidia cards have had for so long. No more ‘70’ and ‘80’ cards if the speculation proves to be correct.

The speculated in-development Turing hardware would be the base upon which the cards are built, but information on that is just as flimsy as anything else.

Why is the next generation of cards taking so long to arrive?

The lack of news on these cards could be for any number of reasons, or none at all, but we have some educated guesses.

The current price of graphics cards is at an all-time high thanks to the increased popularity of cryptocurrency mining, and also the increase in price of the components themselves. Smartphones have been catching up on the hardware front rapidly, and the amount of DDR4 ram going into the higher end models is starting to rival that of mid-tier PCs – causing a fairly severe RAM shortage.

The idea that a new generation of cards could arrive, and be more expensive than the already sky-high prices of the current GFX card market, would probably not sit well with many people.

The important thing to note about the current market is that Nvidia is not really under any pressure to create new cards. Both the 1080 and 1080Ti are leading the market in terms of performance, and there is no offering from AMD to change that. AMD cards are also heavily favoured for cryptocurrency mining, which means they’re also harder to find, pushing even more of the market into Nvidia’s grasp.

What about performance and specs?

It’s way too early to say if the new generation of cards will deliver the kind of significant performance gains that Pascal did over Maxwell.

What's slightly clearer is the process the GPU will use. Intel is moving to 10nm for Cannon Lake, and that was the plan for Volta. However, shrinking the transistors is difficult (part of the reason why Intel is stuck with 14nm for four whole generations of Core processors) and the existing Volta chips ended up using a 12nm process from TSMC – the company that makes the chips for Nvidia.

The Tesla V100 and Titan V cards both use HBM - high-bandwidth memory - just like AMD's Vega cards. Previous consumer cards from Nvidia have gone with traditional GDDR RAM and while it would be nice if Nvidia kept the technically-better HBM for Volta-based cards, it may not happen.

That's because memory manufacturer SK Hynix published a press release in April 2017 which “introduced the world’s fastest 2Znm 8Gb(Gigabit) GDDR6(Graphics DDR6) DRAM. The product operates with an I/O data rate of 16Gbps(Gigabits per second) per pin, which is the industry’s fastest. With a forthcoming high-end graphics card of 384-bit I/Os, this DRAM processes up to 768GB(Gigabytes) of graphics data per second.”

It didn’t specify which manufacturer that graphics card was coming from, but with AMD’s Vega employing HBM2 memory and the press release also stating that “SK Hynix has been planning to mass produce the product for a client to release high-end graphics card by early 2018”, you’d assume it was the next-gen GeForce cards.

The Titan Xp with 12GB of GDDR5X has a memory bandwidth of 547.7GB/s, so it’s interesting that SK Hynix’s GDDR6 will run at 16Gb/s and – with a 384-bit interface card – will offer up to 768GB/s. That’s quite a jump: the Tesla V100 – with HBM2 – has a bandwidth of 900GB/s, so a putative Volta-based Titan with GDDR6 wouldn’t be too far behind.

The new Titan V - for context - offers 652.8 GB/s of bandwidth.

We’ll be following the development of the new generation of cards closely, and updating this article when any new rumours (and facts) about the consumer cards surface, so keep checking back.
