Turing fp64 full#

Though RTX 3090 and RTX 3080 are known to use GA102, neither use its complete capability, leaving adequate room for a fully-enabled RTX Titan GPU down the line.

The full GA102 die has 10,752 cores, 84 RT cores, 336 Tensor cores, more cache, more memory bandwidth, and PCIe 4.0 connectivity. Nvidia puts these transistors to work by cramming in more of just about everything that matters for a consumer GPU. The decision not to go with TSMC's 7nm is curious given Nvidia's long-standing relationship with the foundry, but Samsung's leading process has a similar transistor density as TSMC's popular 7nm, so the resultant GPUs would have been of similar size in any case. Known as GA102, it's a beast of a chip, comprising 28.3bn transistors on a 628.3mm² die manufactured on Samsung's 8nm custom process. Here is the usual high-level block diagram of the full gaming version of Ampere. It makes most sense to examine it in the fullest form and then focus on where Nvidia has made improvements over previous generations. So let's dig further into what Ampere is, how it's manifested in the RTX 3080, and then evaluate the validity of Nvidia's bombast performance claims.Īmpere is an evolution of the Turing architecture powering 20-series and 16-series cards. The launch is staggered such that the RTX 3080 is available from today, the champion RTX 3090 on September 24, and the RTX 3070 on October 15. GeForce 30-series is initially represented by the premium RTX 3070, RTX 3080, and RTX 3090. In a sign of the times, Nvidia boss, Jen-Hsun Huang, took the wraps off the all-new GeForce RTX 30-series graphics in none other than his kitchen.īased on the Ampere architecture that first debuted in the datacentre space with the A100 GPU, Nvidia reckons it has doubled the performance from the last generation.
