At CES 2021, Nvidia has launched a variety of graphics cards for both laptops and the new Ampere desktop graphics card, the Nvidia GeForce RTX 3060. But one of the big things I’ve noticed is that some SKUs are currently inflated VRAM specs, which confuses the entire Nvidia RTX 3000 lineup a bit.
The top end of the new mobile stack has a 16GB RTX3080, while the desktop RTX3080 has 10GB. Similarly, the Nvidia GeForce RTX 3060 has 12GB of VRAM, but the RTX 3060 Ti (a more powerful and 20% more expensive graphics card) has as little VRAM as 8GB.
This ultimately results in the limitation of the 192 bit memory bus on which the RTX 3060 is designed, rather than the 256 bit bus of the RTX 3060 Ti. But that makes this graphics card a bit confusing for the average consumer.
Let’s talk about memories
When Nvidia announced the RTX 3060, it emphasized 12GB of video memory and 13 shader TFLOPs, but most of the core specs were omitted. Fortunately, Nvidia has posted them on its website.
The Nvidia GeForce RTX 3060 has 3,584 CUDA cores and a boost clock of 1.78GHz. For comparison, the Nvidia GeForce RTX 3060Ti has 4,864 CUDA cores and a boost clock of 1.67GHz.
However, the most noticeable difference here is in memory. The Nvidia GeForce RTX 3060 is built around the 192 bit bus from the 256 bit bus of the RTX 3060 Ti. So Nvidia basically had to choose between 6GB and 12GB of VRAM on the RTX 3060. It depends on the operation of VRAM.
Each chip in GDDR6 memory has a total of 32-bit data paths. This means that a GPU with a 192 bit bus must use 6 GDDR6 chips. These chips are available in 1GB or 2GB variations, so there is a 6GB or 12GB limit in the first place.
This also helps explain why the mobile version of the RTX 3080 has 16GB of VRAM and the desktop version is still limited to 10GB. Nvidia hasn’t released the full spec for the RTX 3080, but I contacted Nvidia for clarification. Was said:
“The RTX 3080 laptop GPU is the flagship model of the laptop lineup. As a flagship, it has as many features as possible, including 16GB available for those who want the best specs that laptops can support. . “
Nvidia also revealed that the RTX 3080 on mobile has a 256-bit memory bus. This means that the same logic limits it to either 8GB of VRAM or 16GB.
In Nvidia’s honor, when designing both of these GPUs, instead of limiting the mobile RTX 3080 to 8GB or RTX, use memory interface limits to at least provide more value to consumers Seems to have chosen to try. 3060-6GB, you can avoid confusion by doing it.
Let’s get rid of some of that confusion
Nvidia’s decision on these upcoming GPUs makes a lot of sense, but it’s hard to think of anyone on the market for graphics cards who may not be familiar with the world of computing hardware. I can’t. There are two graphics cards on the shelf. One is RTX 3060 Ti and the other is RTX 3060. The names of the cards are very similar. The RTX3060 has a lot of memory and is cheap, so it’s not hard for anyone to imagine. You will pick it up thinking they are getting better value.
However, Nvidia seems to target the same general users as the GTX 1060 (that is, 1080p gamers), so a graphics card with 12GB of VRAM is not much different from an 8GB card in its resolution. be careful. As for guaranteeing the future of the card, I have to say that 8GB of VRAM may be more than enough for 1080p games in the coming years.
The RTX 3060Ti has 35% more CUDA cores than the RTX 3060 and its wide memory bus can be significantly faster for most games. However, the RTX 3060 hasn’t been tested yet, so I’m not sure what the actual performance will be.
However, it’s fun to see exactly where this card is on the market and what the ultimate graphics card is for those looking for powerful 1080p performance. However, there is one obvious thing. Aftermarket graphics card makers need to find a way to make the difference between the RTX 3060 Ti and the RTX 3060 easy for consumers.
