Nvidia prototype graphics card sports 12GB of GDDR6 memory


An image of what appears to be an Nvidia prototype graphics card has thrown more fuel on the fire of gamers everywhere who are still hoping for a next-generation Nvidia GPU before the end of the year. While it lacks a graphics processing core, the card does further back up earlier rumors that suggested GDDR6 memory would play a big role in whatever Nvidia has planned next.

The leaked image of the prototype Nvidia card showed up on Reddit from a user named “dustinbrooks.” While that original post has been deleted, it claimed that the board was an in-development Nvidia graphics card that was undergoing testing. It certainly appears to be a very-much unfinished product with several key aspects of a complete graphics card missing. What it does have though, gives us some intriguing hints about the future.

There are a total of 12 GDDR6 memory chips located around the missing GPU core. TechPowerUp translated their product codes to name them as Micron 8Gbit GDDR6 modules which are rated at a 14Gbps data rate. At 1GB per chip, that would suggest this card has 12GB of GDDR6 memory, though it’s certainly possible that the reverse side also has chips on for an expanded amount. The memory-bus is said to be 384-bit, which is a little wider than the current top-tier GTX 1080 Ti’s 352-bit bus. That, combined with the higher rated-speed of the GDDR6 memory would suggest that this card has a total memory bandwidth of 672 GBps — substantially more than the 1080Ti’s 484GBps.

Speculation about the size of the missing graphics chip suggests it is more likely to be a successor to the GP102 core found in the 1080Ti graphics card than the GV100 which is found in Nvidia’s Titan V and Quadro business-orientated cards.

Other details about the board are interesting, though less likely to make it through to a final card. There are three eight-pin power connectors, which as TechPowerUP highlights, suggests that this is a testing board with a much higher power draw than any kind of consumer card would have. The outcome of tests with this board, could provide the basis for whatever the eventual commercial card ends up being.

If you can’t wait for whatever Nvidia is working on, these are the best graphics cards you can buy right now.

We talk a lot about the best graphics cards, but no one is buying them right now. According to a new report from Jon Peddie Research (JPR), GPUs have experienced a dip of nearly 13% since last quarter, which already saw bad sales, and have fallen nearly 40% compared to the same time last year.

In total, JPR says that there were 6.3 million boards shipped in the last quarter. For context, in the last quarter of 2021, at the height of the GPU shortage, there were over 13 million boards shipped.

Here’s how Nvidia defends its RTX 4060 Ti’s memory controversy
nvidia rtx 4060 ti 8gb 16gb memory controversy nvidia02

The rumors are true: Nvidia has two versions of its new RTX 4060 Ti graphics card. These are the highly anticipated new midrange GPUs, and yes, one comes with 8GB of VRAM and one comes with 16GB -- and they're separated by $100 in price.

It's a head-scratching decision on a few different levels. Games that demand more than 8GB of VRAM are increasingly common, which is frustrating for those eying the $399 8GB model. What's more -- the RTX 4070 Ti comes with just 12GB of VRAM, despite costing $599.

Nvidia isn’t selling graphics cards — it’s selling DLSS

Nvidia does, of course, sell graphics cards. In fact, it sells most of the best graphics cards on the market. But more than ever before, the company is increasingly hanging its hat on its impressive Deep Learning Super Sampling (DLSS) to sell GPUs rather than raw performance.

The RTX 4090 stands as a crowning achievement in the world of consumer graphics cards, but once you get down into the cards that most gamers will actually buy, the generational improvements start to slip. This became abundantly clear with the launch of the RTX 4070. The card has been well-received, and I even awarded it a rare Editor's Choice award in my RTX 4070 review. But that's despite its generational improvements, not because of them.
