Sometimes better than the portable RTX 3070, sometimes less…

At equal TGPs, the RTX 3070 Ti outperforms the RTX 3070 by about 8-10%; But when configured with a lower TGP, the Ti variant struggles to justify its suffix.

At the beginning of the year, NVIDIA boosted its offering of graphics cards for laptops with a graphic GeForce RTX 3080 Ti and RTX 3070 Ti for mobile phones. We already had a glimpse of RTX 3080 Ti . performance In a few games at the end of January thanks to a video from HardwareCanucks. It’s GeForce RTX 3070 Ti’s turn for review by Notebookcheck this time. At the same TGP, this reference is about 8-10% higher than the RTX 3070. On the other hand, with a more limited TGP, it can position itself well behind the non-Ti version.

Compared to GeForce RTX 3070, GeForce RTX 3070 Ti has more cores: 5888 CUDA cores vs 5120, 44 RT cores vs 40, 176 Tensor cores vs 160. No difference in VRAM (8GB at 14Gb/s on a 256-bit bus in both cases). Finally, the TGP range oscillates between 80 and 150 watts.

Notebookcheck compared the performance of three machines in tests (3DMark) and games (The Witcher 3, Far Cry 5…). Two MSI computers, the Vector GP66 and Stealth GS66, feature a GeForce RTX 3070 Ti card. The card has a TGP of 150W in Vector, 105W in Stealth; The boost frequencies are 1485MHz and 1035MHz respectively. The third laptop is the XMG Apex 17 with 145W RTX 3070 from TGP.

Beware TGP

Overall, the Vector GP66 outperforms the XMG Apex 17 by about 8-10%. On the other hand, despite the GeForce RTX 3070, the latter is more efficient than the Stealth GS66.

Note that all computers have different processors. Just in principle, the Core i7-12700H doesn’t put Stealth at a disadvantage against the XMG and Ryzen 7 5800H, even if the Intel chip has a more restrictive TDP.

All these results confirm one thing: when buying a laptop, you should not stop at the name of the components. As Notebookcheck shows, a computer equipped with an RTX 3070 can be much more powerful than a computer equipped with an RTX 3070 Ti. Feel free to consult the source to discover all the scores.
