EXTRAS
The NVIDIA RTX 4090 Ti is not the fastest GPU, will there be a TITAN ADA?
We start the week very strong and with new revelations, since the RTX 4090 Ti returns to the scene after being seen only two days ago. And it is that you have to go back to July of last year to understand what is happening with this new graphics card, or rather, with these new graphics cards. Because yes, the RTX 4090Ti It will not be the only GPU that is in the oven, since apparently yes that finally there would be a TITAN Ada on the way.
Be careful with the twist in the script that we have before us and that we are going to try to explain in the simplest way. The important thing is to understand the chronological order of events, because we are going to travel to the past, present and future in this article, or at least, we are going to try. Also, take a pinch of salt, and said that, to the mess.
NVIDIA RTX 4090 Ti and RTX TITAN Ada, the monsters that will arrive

The images we saw this weekend with the 4-slot monstrosity turns out that it could be the TITAN Ada and not the RTX 4090 Ti as such. How do we know? Well, because in July 2022 the information that there would be a GPU with SKU PG137-SKU0 with the chip AD102-450-A1with 48GB of 24Gbps GDDR6X VRAM and a total consumption of 800 watts.
Well, the image we saw not long ago showed precisely that screen-printed PG137, and also, just a few moments ago kopite7kimi has dropped the bomb ensuring that the RTX 4090 Ti will use PG136/139-SKU310 with 18,176 FP32 Shadersin addition to 96MB of L2 and a memory 24Gbps GDDR6X with a total sum of 24GB capacity.

So… What chip will it have? well the AD102-400-A1. As all this is very confusing and the segmentation in the upper part is less and less in terms of benefits, we are going to compare the three models that make up the elite line of NVIDIA to make it easier to understand everything.
Three GPUs to fight AMD for the throne
| The Computer Tinkerer | RTX 4090 | RTX 4090Ti | RTX TITAN Ada |
|---|---|---|---|
| GPUs | AD102-300-A1 | AD102-400-A1 | AD102-450-A1 |
| Shaders | 16,384 | 18,176 | 18,176 |
| L2 | 72MB | 96MB | 96MB |
| PCBs | PG136D-SKU300 | PG136/139-SKU310 | PG137-SKU0 |
| VRAM | 24GB to 21Gbps | 24GB at 24Gbps | 48GB at 24Gbps |
| PTB | 450W | 600W | 800W |
And it is that NVIDIA does not get distracted or lower its guard. Information they must have, since given the difference in performance between the RX 7900 XTX and the RTX 4090 they should be calm, but no. It seems that the rumor of AMD’s Dual GPU is gaining strength behind the scenes and hence these two monsters that are yet to come.
As can be seen from the table above, the RTX 4090 Ti and RTX TITAN Ada only differ in the PG137 and its SKU, as well as the amount of VRAM available. But then why doesn’t NVIDIA take full advantage of the AD102 with its 18,432 Shaders on the TITAN? Well, it is not clear, but there is a margin. It may be because it seeks to maximize costs by launching the same chip that uses the RTX 6000or it could be an error given the date of the leak and it does offer the AD102 in full with its 18,432 Shaders.
What we do know is that there is consumer segmentation as we see in the table above, which makes us think of different frequencies for the TITAN (for the better) or that, indeed, it will have the entire chip.

In theory, what we saw at the weekend was the RTX TITAN Ada, hence its bigger heatsink. It is possible that the RTX 4090 Ti will come with the same as the RTX 4090 currently being sold, since it has proven to be effective in working with those. 600 watts commented in the table.
