Nvidia GeForce RTX 3070 Ti Review – Introduction

Simultaneously with the RTX 3080 Ti, Nvidia announced the RTX 3070 Ti. However, the company spread the benchmark and review embargoes over two Tuesdays with a week in between. The latest card in the Ampere family should be 50 percent faster than its predecessor, the 2070 Super, and with additional CUDA, Tensor and RT cores, the card should of course also leave the regular RTX 3070 behind.

Faster memory for the GA104 GPU

By far the most eye-catching specification of the RTX 3070 Ti is the type of memory. Like the much more luxurious GeForce cards in the RTX 30 series, the 3070 Ti has GDDR6X memory, which offers even higher speeds than normal GDDR6. Thanks to a memory speed of 19Gbit/s over a 256bit bus, the 3070 Ti has 608GB/s memory bandwidth, where the 3070 has to make do with 448GB/s. This means that the RTX 3070 Ti has over 35 percent more memory bandwidth than the normal RTX 3070, while the number of enabled cores on the RTX 3070 Ti is only slightly more than 4 percent higher. Because modern GPUs are almost by definition limited in their performance due to the total bandwidth of the memory, the RTX 3070 Ti already seems a lot more interesting on paper than the regular RTX 3070. We will find out in this article whether this is also the case in practice. review.

The RTX 3070 Ti has a fully enabled GA104 GPU, with all 6144 cores active. This is a small step forward from the normal RTX 3070, which comes out at 5888 cores. Yet the tgp with 290W is more than 30 percent higher. How is that possible? This difference is almost entirely due to the GDDR6X memory on the 3070 Ti, which runs at much higher speeds and consumes considerably more energy than the normal GDDR6 memory as used on the RTX 3070, among others.
