老外对新switch所用的T214芯片做的评价 Well, unfortunately, we don't know that much about it. Digital Foundry speculates that it's likely the T210B01 will keep the same configuration as the T210, however. That means 4 ARM Cortex A57 CPU cores, 256 shading units in its GPU, and seemingly even keeping the same 4GB of RAM. What we can look at however is once again the source code. Voltages are reduced compared to the standard T210. The GPU clock in the T210 maxes out at 1000 MHz (with a maximum of 921 MHz supported on Switch, though no game thus far has gone past 768 MHz), however, the new T210B01 maxes out at 1267 MHz instead, around a 25% improvement to GPU clocks. What this all points to is that the T210B01 will keep the same basic silicon, but will downsize to a smaller fabrication process, perhaps 14 or 16nm, instead of 20. This would allow Nvidia to clock the T210B01 higher, while using less voltage and less power. Now, there are 2 ways Nvidia could go about this. They could keep power levels the same, but increase the performance entirely. Or they could try to go for a lower power focus, where maybe clock speeds remain the same, but battery life is improved in portable mode. At best, we could probably expect that same 25% GPU uplift in the Switch version of the chip, which would place it around that 921 MHz level in docked mode at a similar power profile to the 768 MHz T210. Certainly, for those hoping for a major Switch revision with much improved performance, this is fairly disappointing. It's more like a New 3DS than a PS4 Pro, very small improvements, but not really all that much. EDIT: For comparison, Breath of the Wild runs at up to 900p on Switch. 1080p is a 44% increase in resolution over 900p, so the 25% performance uplift would not even be enough to get Breath of the Wild to 1080p on the potential revised model.
