Nvidia GTX 980 Ti Features GM200-310 GPU, 6GB of GDDR5 - Will Debut With Reference And Custom Coolers

Nvidia'southward upcoming GeForce GTX 980 Ti graphics card will reportedly feature a GM200-310 GPU and 6GB of GDDR5. The new card is likewise set to debut with both reference and non-reference AIB specific custom cooling solutions that range from air, water and hybrid cooling solutions.

According Videocardz.com, the GTX 980 Ti nomenclature can be confirmed for the upcoming bill of fare at this point according to their ain sources. This is interesting as information technology was up for contend whether Nvidia was going to introduce one new single-GPU GM200 based 900 series bill of fare or more. Now information technology seems in that location will only be one GM200 based single-GPU solution in the 900 series. This is because at that place'due south simply no room for another addition between the GTX 980 and GTX 980 Ti.

Nvidia GeForce GTX 980 Ti Features GM200-310 GPU, 6GB of GDDR5 - Volition Debut With Reference And Custom Coolers

Videocardz too confirmed that the GTX 980 Ti will feature the aforementioned brandish oututs. Namely a single DVI, a unmarried HDMI and three DisplayPorts. The card volition also accept ane 8-pin and one 6-pin PCIE power connectors. These are the only specifications that tin be confirmed equally of correct now co-ordinate to the report.

At that place's besides an interesting discussion to be had with regards to the GM200-310 GPU. Every bit information technology differs from the GM200-400 GPU inside the Titan X. Both "total fat" fully unlocked versions of Nvidia's GM200 and GM204 GPUs inside the Titan X and the GTX 980 have a -400 suffix. The -310 suffix for the 980 Ti could indicate that it volition actually have fewer CUDA cores than the Titan X, but that is yet to exist confirmed. I should also point out that a-300 suffix does not necessarily mean a cut down die. For example the GM206 GPU powering the GTX 960 has a -300 suffix even though information technology's a fully unlocked GPU core. Then it'due south still to be seen how GM200-310 differs from GM200-400.

Now an even more interesting question is if the GTX 980 Ti does truly take a total GM200 GPU with 3072 CUDA cores every bit was previously rumored, where will the cut downwards GPUs go ? This might seem like a foreign question to some because why would Nvidia want to sell a cut down version of GM200 if they can sell the fully unlocked GPU core ? Unfortunately this is where the ruthless nature of semiconductor economics shows its face up, problems like yield and manufacturing defects simply necessitate information technology.

To understand this dilemma i must start empathise how GPUs are manufactured. Integrated circuits like GPUs and other processors are photochemically printed on what is called a Silicon wafer. This process is actually far more than complex than what it sounds like. And information technology often takes 2 to three months for a wafer order to materialize into actual working chips. A Silicon wafer with a 300mm diameter has a total area of 70650mm² but if we accept into account things similar the shape of the GPU die, the size , die spacing and so on we arrive at an estimate of 91 GM200 dies per 300mm wafer.

This is where yield comes into play. You lot simply can't produce a wafer with 91 perfect GM200 dies. In fact the bulk of the dies will take a manufacturing defect of some sort, ranging from a skilful number of very minor defects to a few significant ones that return the die completely unusable. The larger the dice the more likely it will incorporate a manufacturing defect and GM200 is a massive dice. Only a limited number of dies would come out unscathed in any given wafer.
The location of the die within the wafer also plays an important role in defect density. As y'all movement further away from the center of the wafer the higher the defect density becomes. And so the premium "cherry picked" chips are usually taken from the center. In the example of GM200 those are the ones that cease up as GM200-400 GPUs in the Titan X. These will have 24 out of 24 fully functional SMM units with 128 CUDA cores each, amounting to 3072 CUDA cores.

The style the semiconductor manufacture has dealt with this issue for the by several decades is by disabling the defective structures, under-clocking the scrap or a combination of both. Depending on the blazon and severity of the defect. These chips are then sold as lower end SKUs. Then each manufactured wafer volition yield a number of chips with different quality levels and thus a dissimilar number of SKUs.

In the case of GPUs, both Nvidia and AMD would simply disable a number of SMM / CU units containing defective/malfunctioning CUDA or GCN cores and then slightly lower the clock speeds to sell the GPU. This is what differentiates the GTX 980 from the GTX 970 and the R9 290x from the R9 290 for example. However I should betoken out that in some cases, although less normally, fully functional dies would be purposefully cut down but to run across demands for lower end SKUs.

Nvidia then far has merely been selling fully functional GM200 GPUs, GM200-400, in the Titan X and Quadro M6000 cards. Then during all of this time, recovered / cut downward GM200 GPUs take been accumulating as wafers are fabricated and they accept to exist eventually sold, otherwise a huge amount of dies on a wafer would be thrown away. Which would be financially detrimental as no company can afford to exercise this. Selling these recovered GM200 GPUs every bit GTX 980 Ti cards makes the most sense.

If they don't end upwardly in 980 Ti cards they have to finish up in some other product. Simply there's simply no room to fit an additional SKU between the GTX 980 Ti and the 980. Quadro and dual-GPU GeForce cards sell in considerably lower volumes than single-GPU GeForce cards, and then they won't be plenty to consume the inventory. A cut downwardly GM200 GPU has to find its way to a single-GPU GeForce card. Nosotros just don't know withal for certain if that card is the GTX 980 Ti. Simply considering semiconductor manufacturing economic science and the GM200-310 code name we do think information technology'southward a 18-carat possibility.
