At six o’clock tonight, Nvidia aired a pre-recorded event in which CEO Jensen Huang introduced the new Ampere video cards for gamers. A lot had already been leaked about the GeForce RTX 3070, RTX 3080 and RTX 3090, but Nvidia nevertheless managed to surprise on points – the new GPUs appear to have twice as many Cuda cores as previously suggested. In this preview you can read everything we know so far about Nvidia’s brand new gaming cards.
Nvidia GeForce RTX 3000: Ampere + 8nm
The main innovations in the GeForce RTX 3000 series are the Ampere architecture, which succeeds both the Volta architecture for servers and the Turing architecture for gaming, and Samsung’s 8nm process ‘co-developed with Nvidia’. This process is a further development of Samsung’s 10nm process, which means that no EUV is used in production yet.
The line-up: RTX 3070, RTX 3080 & RTX 3090
The line-up currently consists of three models, with the flagship GeForce RTX 3090 (nicknamed BFGPU – feel free to think for yourself what that stands for) based on the GA102 GPU. In fact, this is the successor to the RTX 2080 Ti (or even the Titan RTX, as Nvidia itself says), which contained the TU102 chip, but to simplify the naming, they simply chose a higher model number this time. The RTX 3080 is based on the same chip, but with 17% fewer computing units enabled. Only the RTX 3070 uses the GA104 chip – for comparison, the TU104 was already used for the RTX 2080 in the previous series.
|RTX 3090||RTX 2080 Ti||RTX 3080||RTX 2080||RTX 3070||RTX 2070|
|Architecture||8nm, GA102||12nm, TU102||8nm, GA102||12nm, TU104||8nm, GA104||12nm, TU106|
|Vram||24GB gddr6x||11GB gddr6||10GB gddr6x||8GB gddr6||8GB gddr6||8GB gddr6|
|Memory Speed||19.5GBit / s||14Gbit / s||19Gbit / s||14Gbit / s||16Gbit / s||14Gbit / s|
|Bandwidth||936GB / s||616GB / s||760GB / s||448GB / s||512GB / s||448GB / s|
Later in this article we will discuss the most important new features of the Ampere architecture, the GA102 and GA104 GPUs already mentioned and the design of Nvidia’s own Founders Edition. We must rely entirely on what Nvidia announced today; no samples have arrived in our lab yet and the extensive press briefings, which usually go deeper into the architecture, have not yet taken place. Fortunately, the first GeForce RTX 3000 video card will be in the shops on September 17, so it will not be too long to wait for all the details and of course extensive, independent benchmarks – but that does not mean that we are holding you back from our preliminary analysis.
