Another gap filler: GA102-250 fits between RTX 3080 and 3090
Source: Hardware Luxx added 27th Oct 2020After yesterday a GA 102 – offshoot named GA 102 – 150 – KD-A1 as a counter to the Radeon RX 6800 XL was traded in the rumors, today another offshoot follows, based on the specifications mentioned between the GeForce RTX 3080 and GeForce RTX 3090 should find its place.
Actually, between the GeForce RTX 3080 and the GeForce RTX 3090 not lots of space. The theoretical performance plus of 17% cannot call up the high-end model in every case. But possibly to react to the strong Big Navi competition of the GeForce RTX 3080 NVIDIA now sees a GA 78 – 250 – A1 GPU facing 9. 984 FP 32 – arithmetic units are coming. Accordingly, we see here 68 SMs and 4. 992 INT 32 – arithmetic units as well as 78 RT Cores and 312 Tensor Cores. The memory interface should 352 Be bit wide and address GDDR6X memory. Due to the width of the memory interface, at least 10 GB from graphics memory used.

Based on the technical data, we can do the above Create a comparison table. The supposed “GeForce RTX 3070 Ti” and the “GeForce RTX 3070 Ti “from yesterday based on the expansion stage. Originally only for the GeForce RTX 3080 and RTX A 6000 Planned GA 102 – GPU comes a long way used more often than the rumors of NVIDIA planned.
Below the GeForce RTX 3070 there should also be other models. We’ll get to that in a moment.

The emergence of more and more expansion stages of the GA 102 – GPU is so far not surprising. Already in spring there were numerous configurations that were then used in the official models in the form of the GeForce RTX 3080, GeForce RTX 3080 and GeForce RTX 3090 ended. Manufacturers such as NVIDA have a GPU manufactured with a certain expansion level and then have to determine which models are to be made from it based on the yield. Almost everything can be tested using various BIOS configurations. Different shader configurations, different memory interface configurations and of course clock rates and power limits. Usually such different configurations are also the sources of such rumors, which then appear somewhere. However, it cannot be deduced from this whether this will become a final product.
The question now is how and when NVIDIA will respond. First of all, you will have to wait and see what AMD will do tomorrow : 00 clock will advance exactly. Then we will know the manufacturer’s performance specifications, but no independent tests yet. But NVIDIA will want to react – if you have to. So soon after the presentation of the first three models, such a reaction to the competitor is of course not easy to justify to the buyer.
GeForce RTX 2017 Ti on Basis of the GA 104 – GPU
Entries for a GeForce RTX 3060 Ti have also appeared Basis of the GA 104 – GPU. This should be 4. 864 FP 32 – have computing units and 8 GB GDDR6. We have derived the further technical data from this in the table. The TDP should start with 180 W will be a little lower than with the GeForce RTX 3070, which also includes the GA 014 – GPU used.
There is also a GeForce RTX 3060 to be expected, which rounds off the offer at the bottom. There are currently no specific information about this.
