TL;DR: NVIDIA GeForce RTX 3070 Ti & 3080 Ti 12GB performance in OctaneRender
The RTX 3080 Ti offers nearly identical performance to the RTX 3090 for a lower price, as long as VRAM is not an issue. With half the VRAM of the RTX 3090, this new card may not be for everyone, especially those with large and complex scenes. In those instances, the RTX 3090's massive 24GB VRAM is still unmatched. However, for those that only need the 12GB offered by the new RTX 3080 Ti, this new card offers top of the line performance at a lower price.
The RTX 3070 Ti renders about 10% faster than the base RTX 3070, and 19% slower than the RTX 3080. It does also have less VRAM than the RTX 3080. There are several much faster options available, but it still offers good performance for the money.
NVIDIA has a tradition of releasing "Ti" variants of their video cards which serve as a more powerful variant of the base model and often fill gaps between product tiers. The launch of the RTX 3080 Ti continues this trend. Compared to the base RTX 3080, the new RTX 3080 Ti has 2GB more VRAM (12GB versus 10GB) and 18% more CUDA cores, although the maximum boost clock is a bit lower. In fact, in terms of performance, the RTX 3080 Ti should be closer to the RTX 3090 than it is to the RTX 3080.
The RTX 3070 Ti takes a different approach. It only has a small bump in CUDA cores, just 4% more than the base RTX 3070, but has a faster clock speed paired with the faster GDDR6X VRAM. While there aren't many more cores, it should be able to utilize those cores more faster.
Professional applications such as Chaos's V-Ray scale very well with the number of available CUDA cores and extra VRAM is always useful. Both of these new cards should provide interesting results, one card relying on faster cores, while the other relies on more cores.
If you want to see the full specs for the latest NVIDIA GPUs we recommend checking out the NVIDIA GeForce RTX 30 Series product page. But at a glance, here are what we consider to be the most important specs:
|RTX 3060||12GB||3,584||1.78 GHz||170W||$329|
|RTX 3060 Ti||8GB||4,864||1.67 GHz||200W||$399|
|RTX 3070||8GB||5,888||1.70 GHz||220W||$499|
|RTX 3070 Ti||8GB||6,144||1.77 GHz||290W||$599|
|RTX 3080||10GB||8,704||1.71 GHz||320W||$699|
|RTX 3080 Ti||12GB||10,240||1.67 GHz||350W||$1,199|
|RTX 3090||24GB||10,496||1.73 GHz||350W||$1,499|
As we noted earlier, the RTX 3080 Ti has 2GB more VRAM than the RTX 3080, and has close to the same CUDA core count as the RTX 3090. Price-wise, it is $500 more than the RTX 3080, or $300 less than the RTX 3090. On paper, it looks to be a great card for those that need high GPU performance, but not necessarily the large 24GB of VRAM that is found on the RTX 3090.
One concern we have is that this is a 350W card – just like the RTX 3090 – but uses a 2-slot cooler that is essentially the same as what is on the lower wattage RTX 3080. In our testing, this makes it both louder and hotter than any other RTX 3000 series card, which can be a significant concern if your system does not have adequate cooling.
Listed below is the specifications of the system we will be using for our testing:
|CPU||AMD Ryzen 9 5900X 12-Core|
|CPU Cooler||Noctua NH-U12AP|

To test each video card, we used OctaneBench 2020.1.5. These tests were run twice on each GPU, with the best result being included in the graphs below.
Here are charts showing the performance of the new GeForce RTX 3070 Ti and GeForce RTX 3080 Ti (in green) compared to the other cards we tested:
The raw performance of the RTX 3080 Ti is quite impressive and lines up about where you would expect given its specifications. It should be noted that this benchmark does not fill up the available VRAM, so larger more complex scenes that need more than the 12GBs available would see different numbers. However, if that is not your case, the RTX 3080 Ti offers nearly identical performance to the RTX 3090.
The RTX 3070 Ti is roughly 10% faster than the base RTX 3070 and about 19% slower than the base RTX 3080. This is a little underwhelming, but every bit of rendering power helps in the long run.
How well do the NVIDIA GeForce RTX 3070 Ti and 3080 Ti perform in Octane?
The RTX 3080 Ti offers nearly identical performance to the RTX 3090 for a lower price, as long as VRAM is not an issue. This makes for interesting options for Octane users. Those that only need 12GB of VRAM can get similar results to the existing RTX 3090 but at a lower cost. While those that need lots of VRAM have an option that is only a few hundred dollars more. In the previous generation, we saw similar performance and VRAM options with the RTX 2080 TI and RTX Titan, however, in that case, the Titan was more than double the cost of the 2080 Ti.
The RTX 3070 Ti renders about 10% faster than the base RTX 3070, and 19% slower than the RTX 3080. It also has less VRAM than the RTX 3080. The performance gains are a bit underwhelming given the cost.
One concern we do have is that this card draws as much power as the 3090, but has a much smaller cooler. So far in our testing temperatures of a single card have been within the specs laid out by Nvidia. Currently there is no blower style card, so stacking 3 or 4 in a system isn't an option.
As always, keep in mind that these results are strictly for Octane. If you have performance concerns for other applications in your workflow, we highly recommend checking out our Hardware Articles (you can filter by "Video Card") for the latest information on how a range of applications perform with the latest NVIDIA and AMD GPUs, as well as with different CPUs and other hardware.
