Beyond that explanation, though, game development is going a different direction with post-processing and compute-oriented effects that aren't friendly to alternate-frame rendering. There aren't many gamers who pair up mainstream GPUs, and the company doesn't want to spread resources thin, so it's focusing on optimizing SLI on faster Pascal-based cards. Officially, Nvidia internalizes the decision. Sure, the GeForce GTX 750 Ti didn't have it, but the 760 did. Generationally, this is the highest-end board we can recall without the technology. Notice the lack of an SLI connector up top? Nvidia recommends a GeForce GTX 1070 or 1080 to gamers looking for more performance than a 1060 delivers (of course), and does not support SLI on the 1060. The less-complex processor, coupled with less memory on a simpler PCA, results in a 120W TDP. Whereas the larger GPU is composed of 7.2 billion transistors on a 314 mm² die, Nvidia packs 4.4 billion FinFET transistors into 200 mm² for GP106. Of course, GP106 is manufactured using the same TSMC 16FF+ process as GP104. Finally, Pascal has a new 8:1 mode that combines 4:1 constant compression to 2x2 blocks with 2:1 compression of the differences between them." There’s also a new 4:1 mode that covers cases when per-pixel differences are very small and compressible into even less space. Adapted from our GTX 1080 coverage, " delta color compression tries to achieve 2:1 savings, and this mode is purportedly enhanced to be usable more often. ![]() Although that figure is lower than the GTX 980's 224 GB/s, remember also that Pascal employs new lossless techniques to extract savings in the memory subsystem, effectively increasing usable bandwidth. Nvidia drops 6GB of 8 GT/s GDDR5 onto the board, serving up to 192 GB/s of peak throughput. Like the larger GP104, each controller is associated with eight ROPs and 256KB of L2, adding up to 48 ROPs and 1.5MB of cache. Six 32-bit memory controllers provide an aggregate 192-bit data path. The processor’s back-end is trimmed down, too. The chip benefits from the same optimized timings that let Nvidia crank the clock rates up on GP104, facilitating a base frequency of 1506 MHz and a typical GPU Boost rating of 1708 MHz. GP106 comes equipped with two GPCs, so you end up with a total of 1280 CUDA cores and 80 texture units.
