Good morning,

Can you help me choose a GPU? Are the most important parameters that the GPU should meet to use AutoCad Civil 3d are: 1. Bandwidth, 2. Memory Size 3. Memory Type or should I only read the G3D Mark value? Are there any other points I should take into account when looking for the best solution?

I am looking for a GPU that will meet the best value for money. At the same time, I know that it makes less sense to invest in Nvidia Quadro solutions to work in 2D, hence the search for GPUs that meet the above-mentioned points.

Looking at https://www.videocardbenchmark.net/gpu_value.html will G3D Mark be more important or will Bandwidth, Memory Size and Memory Type be more important?

Thinking about this today:
GPU Bandwidth MemSize MemType
[ GB/s ] [ GB ]
NVIDIA GeForce RTX 3060 12 GB 360.0 12 GDDR6
AMD Radeon RX 6800 512.0 16 GDDR6
GeForce RTX 4060 272.0 8 GDDR6

The only bit I know about professional CAD software is that some vendors only provide support for specific cards using approved drivers. That was when I was working at a manufacturing company supporting the design and engineering group. So check that, a Quattro may be the better choice.

If you are 100% sure that special nVidia Studio drivers won't be required for any of the applications (for example, you launch an application and it complains studio drivers not installed), then the RX 6800 is the best buy among the above, in terms of pure processing power.

The nVidia professional equivalent of the RX 6800 is the RTX A4500. On the AMD side it's W6800 but it is way too expensive so in your case, I think the RTX A4500 would be the sensible choice, unless you want to go with Radeon Pro W6600 which has only 8GB VRAM and slightly less performance than Geforce RTX 3060 12GB.

Thank you for the really accurate tips and contribution to help in finding the best solutions. Your suggestions are invaluable.

A very long time ago over 20 years ago I had one AMD processor. I didn't complain not to him, but I've always used Intel ever since. This time it was different and I opted for the AMD Ryzen 9 5900X.

There were a few memory issues with my assembled PC, but it wasn't the processor's fault. Needless to say, this is my first time with AMD in a long time.

However, I've never had an AMD series graphics card. I'm wondering if the card with the Nvidia chip will not quarrel with the card with the chip from AMD. I know, maybe it's stupid that I have such prejudices and there will certainly be people who will clearly write how it really is.

Finally, I will ask whether, despite the best value for money for the RX 6800, is it not worth staying with the RTX chip due to previous experience with cards. Tell me what do you think about it?

Haven't heard of any reports of nVidia cards misbehaving with an AMD CPU.

If you have the possibility of returning the RX 6800, get it and test it for your use cases. If you are not satisfied with it, return it and get the RTX. However, if returning is not an option, I guess the RTX card would make more sense to get, even at a higher price, if you intend to keep it for a long time. Depending on how productive it makes you, it could pay off its price within a short period of time and be worth investing in.

Thank you for all your tips and time.
In the header post, however, I raise a thread about the direction of selection in terms of:
1. GPU bandwidth,
2. GPU memory size,
3. GPU memory type.
While we can assume that the newer the type of memory for example GDDR6 and the memory size for example 12GB, we can implicitly know that the newer and larger the memory, the better. In the case of the first point, i.e. the possibility of GPU throughput, such consideration was the basis for writing the post.
In your statements, I did not find any technical or test basis justifying the indicated choices

My recommendations based on the chart here: https://www.techpowerup.com/gpu-specs/rtx-a4500.c3849

4060 and 3060 are not even on the chart. That means they offer less than 72% performance. RX 6800 is the best option provided it works flawlessly for your workloads. But the safest option is RTX A4500 since it is certified for professional use and that certification is what you pay the higher price for.
