A Se­cond Form of Pas­cal The era of the Maxwell GPU is of­fi­cially over, and now comes the days of the Pas­cal GPU. But un­like the Pas­cal GPU that was un­veiled dur­ing GTC this year, the GeForce vari­ant of this Pas­cal GPU isn’t built on the foun­da­tions of NVIDIA’s all­new pow­er­ful HBM2 for­mat.

We bet you’re won­der­ing what the Founders Edi­tion moniker stands for. It’s ac­tu­ally just NVIDIA’s way of say­ing ‘ref­er­ence de­sign’, as well as be­ing a graph­ics card that NVIDIA them­selves will of­fer to con­sumers directly, rather than just grant­ing the rights to its man­u­fac­tur­ing part­ners.

Aside from that fact, the GTX 1080 Founders Edi­tion is still very much us­ing the new 16nm FinFET process, GP104 Pas­cal GPU ar­chi­tec­ture, but in­stead of HBM2, the card uses the re­cently in­tro­duced GDDR5X mem­ory for­mat. More specif­i­cally, it comes equipped with 8GB of GDRR5X mem­ory that’s been clocked at 10,000MHz, and a core GPU clock of 1,607MHz that’s been fac­tory over­clocked to 1,734MHz. Cou­ple that with a 256-bit mem­ory bus and an ef­fec­tive band­width of 320GB/s, what you have is a gamer-ori­ented card that is set to roll through graph­i­cally-de­mand­ing 4K ti­tles, along with the re­cently rein­car­nated medium of Vir­tual Re­al­ity (VR). Ad­di­tion­ally, the card also has 2,560 CUDA cores.

NVIDIA has stated that Pas­cal is more power ef­fi­cient and more graph­i­cally driven than the GTX 980 Ti and the TITAN X. To give you an idea as to just how pow­er­ful this card re­ally is (be­fore we jump into the bench­marks and per­for­mance num­bers): the GTX 1080 Founders Edi­tion is a 180W card that runs off a sin­gle 8-pin PCIe power port, which ran our games at 4K res­o­lu­tion with­out a hitch. Both the GTX 980 Ti and the TITAN X are both 250W that run on one 8-pin and one 6-pin PCIe port, and we wit­nessed both cards strug­gling with some ef­fort to ac­tu­ally main­tain a de­cent fram­er­ate at the same res­o­lu­tion level.

How the GTX 1080 Founders Edi­tion is able to main­tain its break­neck per­for­mance ba­si­cally boils down to its four Graph­ics Pro­cess­ing Clus­ters (GPCs). These GPCs con­sist of 20 Stream­ing Mul­tipro­ces­sors (SM), and each SM is fused to­gether with a Poly­morph En­gine to cre­ate some­thing known as a Tex­ture Pro­cess­ing Clus­ter (TPC). Long story short: it’s these TPCs that help the card per­form tasks, such as tes­sel­la­tions and per­spec­tive cor­rec­tion.
