Nvidia has finally confirmed its most worst-kept of secrets. The GeForce GTX 1080 Ti is coming next week and the firm claims that the $699 card is actually faster than the $1200 Titan X Pascal. If you're looking for a more affordable PC GPU capable of delivering graphically rich 4K gameplay at 60fps, this is the product for you.In producing a Ti spin-off of a Titan product, Nvidia has historically chosen a number of approaches - culling CUDA cores and/or dropping the amount of VRAM included on the board. These downgrades usually have a fairly minimal impact on performance but regardless, GTX 1080 Ti actually has the most minimal cuts we've seen. Essentially, the 12GB of GDDR5X is reduced to 11GB - a very odd compromise, it has to be said - which means that the memory interface is bumped down from 384-bit to 352-bit, ROP count drops from 96 to 88, while 256K of the Titan X Pascal's L2 cache is also omitted.
It's highly unlike that we're going to notice the missing gig of RAM and Nvidia has mitigated the effects of the drop in memory bandwidth by using higher speed GDDR5X - 11gbps vs the 10gbps modules found on the Titan X Pascal. The end result is that GTX 1080 Ti actually has marginally more bandwidth than Titan X Pascal. From our perspective, the question is how far it can be overclocked further - we already run our Titan X memory at 11gbps with a rock-solid overclock. With 4K gaming, memory bandwidth really is at a premium and needs to be pushed as far as it can go.
