Why the GeForce RTX 4060 Ti could be a killer GPU for compact gaming PCs

Small PCs like Intel’s Raptor Canyon NUC 13 Extreme are absolutely great, but you’re not going to put a GeForce RTX 4080 in one of these things. You could get away with a Radeon RX 7900 XTX, but it’ll still fit in nicely – and that’s a pretty big chassis when it comes to small form factor devices. If you want to build something even smaller, you’ll need a much smaller GPU. Apparently, the GeForce RTX 4060 Ti could fill the bill.

Over the past few days, regular leaker @kopite7kimi has released new specs for both the GeForce RTX 4060 Ti and the standard GeForce RTX 4070. Unlaunched” is expected to reappear under the GeForce RTX 4070 Ti name. These two cards would be the next two steps down from this model.

If we look at the rumored specs, we can see that the GeForce RTX 4070 is cut down by the same AD104 chip used for the RTX 4070 Ti. If the rumor is true, it must severely limit its processing power and probably its raster graphics capability as well. These are in the order of 30%. However, the rumor seems to indicate that it will keep the same memory bus width and memory transfer rate, giving it the same memory bandwidth.

The more interesting part is the GeForce RTX 4060 Ti, at least if kopite7kimi’s predictions are correct. It will reportedly be based on a largely intact AD106 cube. He states it for 4,352 shaders, which, if we assume a 2.6 GHz boost clock, gives a peak compute rate of 23 TFLOPs with single precision. Not too shabby for an x60 part. However, AD106 is known to have only 128-bit memory interface, giving NVIDIA the option of 8 or 16GB.

Worse, the RTX 4060 Ti will appear to come with lower clocked GDDR6 memory instead of the GDDR6X that the GeForce RTX 4070 appears to be using. The combination of narrow bus and mediocre transfer rate gives the hypothetical GeForce RTX 4060 Ti only 288 GB/s of memory bandwidth, less than RTX 3060, RTX 2060, GTX 1660 Super and even the GeForce GTX 1080. Ada’s dramatically increased L2 cache seems to help however to help.

The leaker notes that the reference board is “very short” and that it still uses the CEM5 connector. This is another name for the 12+4 pin 12VHPWR connector. It’s interesting to see it here; kopite7kimi seems to expect the RTX 4060 Ti to launch with a total board power of 220 watts. While this is by no means a low-power part, it’s fairly slim compared to the extremely thirsty models at the top of the product stack. It’ll also likely draw less power when gaming, as we’ve seen with the RTX 4090 and its smaller sibling.
