NVIDIA GeForce GTX Graphics Card Comparison
NVIDIA GeForce 1070 vs. 1080 vs. 1080 Ti vs. Titan Xp
The new Titan Xp increases CUDA cores and clock speeds compared to its predecessors.
Whereas the original Titan X Pascal (and the GTX 1080 Ti) packed 3,584 CUDA cores, the new version upgrades to Nvidia’s GP102 graphics processor,
with 3,840 cores. Those cores are faster as well, with a boost clock of 1,582MHz compared to the Titan X’s 1,531MHz.
The Titan’s already speedy GDDR5X memory is enhanced in the Titan Xp as well, hitting 11.4Gbps—a 1.4Gbps boost over its predecessor.
That gives Nvidia’s new flagship a whopping 547.7GBps of memory bandwidth. The original Titan X hits 480GBps, and mainstream graphics cards
hover in the 200GBps to 250GBps range.

Nvidia GTX 1080 Ti: If you bought a Titan X, look away now

Not content with already having the fastest graphics cards on the market in the form of the GTX 1080 and Titan X Pascal, Nvidia has launched the GTX 1080 Ti, which promises to be even faster.
The GTX 1080 Ti launches the week of March 6 for £699/$699.
How much faster? Around 35 percent when compared the GTX 1080 according Nvidia CEO Jen-Hsun Huang, which makes the 1080 Ti ever so slightly faster than the £1,100/$1,200 Titan X. That’s not surprising considering the 1080 Ti is, for the most part, identical to the Titan X: they both use the same GP102 GPU, with 3,584 stream processors and 224 texture units split across six graphics processing clusters and 28 SMs.
The key difference, and what gives the 1080 Ti a slight edge over the Titan X, is its memory configuration. The 1080 Ti features a rather odd 11GB of GDDR5X memory, which results in a 352-bit memory interface and 88 ROPs instead of the 12GB of GDDR5X, 384-bit interface, and 96 ROPs of the Titan X.
However, the 1080 Ti’s memory runs at 11GHz rather than the Titan X’s 10GHz, giving the new card slightly higher memory bandwidth at 484GB/s. The GPU boost clock is also a wee bit higher at 1.6GHz, with Nvidia promising 2GHz when overclocked. TDP is rated at 250W with power coming in via 6-pin and 8-pin PCIe connectors.

Other improvements include a better vapour chamber cooler on Founders Edition (read: reference) design cards, which Nvidia claims results in quieter performance. Those Founders Edition cards will be priced the same as partner cards too, instead of the premium charged for GTX 1080 and GTX 1070 Founders Editions. Founders Edition cards will launch first, with partner cards following at a later date.
Those with more modest budgets will be pleased to hear the the memory improvements made to the 1080 Ti are trickling down to the GTX 1080 and GTX 1060. A new, pre-overclocked SKU of the GTX 1080 will feature the same 11GHz memory, while a new GTX 1060 SKU will feature 9GHz memory.
