I would expect it to bench pretty much the same as the Shield Tablet. In fact, they are probably almost identical hardware-wise. I'll be interested to see if there is a price difference.
Anand's CPU benchmarks are very browser-oriented. The Shield usually beat all other Android devices, but still lost to the iPad Air. I suspect that has more to do with the quality of Mobile Safari than the differences in hardware. In the GPU benchmarks, the Shield does very, very well. http://www.anandtech.com/show/8296/the-nvidia-shield-tablet-review/4 http://www.anandtech.com/show/8296/the-nvidia-shield-tablet-...
Overall, the K1 has both CPU and GPU paper/marketing specs that are theoretically a little better than an Xbox 360. This is demoed by the 360 game Trine 2 running very nearly as well on a Shield as on the 360. http://www.eurogamer.net/articles/digitalfoundry-2014-can-trine-2-on-android-match-xbox-360-and-ps3 http://www.eurogamer.net/articles/digitalfoundry-2014-can-tr...
edit: Looks like the Nexus has a 2048x1536 screen vs the Shield's 1920x1200. 51% more pixels on the same GPU will be a much prettier at the cost of more GPU|battery strain. Given the high power GPU, that seems like a good trade off for a non-gaming-oriented tab.
- exDM69 12y ago> I would expect it to bench pretty much the same as the Shield Tablet. It's not the same chip as in the Shield Tablet (which has an ARMv7 CPU). The GPU is the same but the CPU is the 64 bit Denver CPU (ARMv8). According to benchmarks should be a fair bit faster, especially in single thread execution.
- Symmetry 12y agoThat's possible, but the Shield has a K1 varient with 4 32-bit A15 cores on the chip while the Nexus 9 has a varient of the K9 that has 2 64-bit Project Denver cores. The graphics are identical between the two versions of the K1 so I don't expect much difference in the GPU benchmarks, but I expect the CPU benchmark comparison to be interesting. On one hand we'll have four 3-wide conventional OoO cores. On the other we'll have two cores that are initially narrow and in order but are 7-wide VLIWs once the code morphing software has had a chance to run.
- Tloewald 12y agoIs that big little cores or four symmetric cores?
- Symmetry 12y agoFour symmetric cores - all A15s. I don't think NVidia has ever done big.LITTLE even though they had a fifth core with the same architecture but different process/gate sizes for lower power in some previous Tegra chips. But you can see from them all having the same max frequency that all four cores are the same.
- szatkus 12y ago32-bit K1 also has the companion core[1] (probaly Cortex A7). [1] http://www.extremetech.com/wp-content/uploads/2014/01/tegra-k1-two-versions-a15-denver-core-640x353.jpg http://www.extremetech.com/wp-content/uploads/2014/01/tegra-...
- lgeek 12y agoThe companion core of the ARMv7 TK1 is a low power Cortex-A15, like the grandparent comment says. This is different from ARM's big.LITTLE which uses different microarchitectures for the two clusters, i.e. Cortex-A15 + Cortex-A7 or Cortex-A53 + Cortex-A57.
