The Geforce RTX 3080 Ti is a high-end graphics card from Nvidia. Equipped with Ampere architecture, the product hits the market with a promise to deliver 150% better performance than the GeForce RTX 2070 Super. The device features 12 GB VRAM memory in GDDR6X standard, 10,240 CUDA cores, and also includes DLSS 2.0 and Ray Tracing technologies to enhance the visual experience in games.
GeForce RTX 3080 Ti Datasheet
|GeForce RTX 3080 Ti|
|GPU||GA102 with 10,240 CUDA cores, 80 RT cores and 320 Tensor cores|
|Speeds||1365 MHz base clock, turbo up to 1665 MHz|
|RAM||12 GB of GDDR6X at 19 Gb/s|
|Memory interface||384 bits|
|GCP||350 Watts, requires 750 Watts source|
The new GeForce RTX 3080 Ti consists of a graphics processor (GPU) that adds up to 10,240 CUDA cores. These cores operate at speeds that can reach 1.37 GHz in the base clock, or else accelerate to 1.67 with the turbo on. The card, therefore, has 1,536 more cores than the RTX 3080.
There are also changes in the RAM specifications. The new GeForce comes with 12 GB of GDDR6X versus 10 GB of the RTX 3080. In addition to more memory, the 3080 Ti also accesses that memory with greater speed, as it offers a 384-bit RAM-GPU connection path. This interface is enough to allow the card to exchange 912 GB/s between processor and memory. The RTX 3080 Ti’s numbers are important because there are already games in circulation, such as Doom Eternal, that use more than 10 GB of graphics memory in 4K.
In addition, the new top-of-the-line Ti also includes other components associated with the Ampere architecture. There are 80 RT cores, dedicated to performing the light ray intersection calculations for real-time Ray Tracing effects during gaming, plus a total of 320 Tensor cores. This hardware is specific to machine learning and is responsible for applying DLSS to games that support the technology.
The RTX 3080 Ti performance numbers that are already in circulation and prove what Nvidia has officially released: the card is as fast as the RTX 3090, guaranteeing twice the performance of the GTX 1070 Ti or 1.5 times the performance of the RTX 2070 Super.
According to Tom’s Hardware, the new RTX 3080 Ti delivers an average of 59.5 fps (frames per second) in Assassin’s Creed Valhalla, running in 4K and ultra. This average is only 0.4 fps lower than is possible, in the same conditions and game, with the RTX 3090. In Dirt 5, the comparison remains, with the RTX 3080 Ti delivering 98.1 fps versus 99.5 for the RTX 3090, again in 4K and ultra.
In Ars Technica’s tests, it is possible to measure the performance of the card in other games. In Red Dead Redemption 2, also in 4K and ultra, the card goes to 73 fps average in 4K and ultra. The RTX 3080, for example, reaches 65.8 in the same conditions. In tests with Ray Tracing activated, the Ti also performs well: using the version of Quake 2 with the new lighting technique, the new Nvidia hardware generates a 39.6 fps average against 30 of the RTX 3080.
There is a cost in power to deliver that much performance and keep 10,240 cores operating at a stable clock. The RTX 3080 Ti has an estimated maximum power requirement (GCP) of 350 Watts under the high-demand situation. The figure is 30 Watts higher than what is indicated for the RTX 3080.
Although it has the potential to need more power to achieve its maximum performance, the card ends up requiring the same power range as the PC source. Nvidia recommends that the user’s computer should have a 750-watt power unit.
Types of use
The RTX 3080 Ti is a very high-performance graphics card and its main application is to run games. But due to its high processing power, the component can also be used in more professional environments – such as video editing islands, 3D modeling, complex simulations – as well as game development and studies related to artificial intelligence.
The RTX 3080 Ti is already available on the international market at the suggested launch price of US$1,199. However, supply problems and high demand make the task of finding the card abroad quite difficult. Due to this, the value tends to increase, so that the GeForce RTX 3080 Ti has already been sold for prices over US$2,000.
