Actually, the ASUS TUF Gaming GeForce RTX 3080 OC should be available much earlier but for various reasons she didn’t make it to us at the start. It is now becoming apparent that this model could be one of the best, which in addition to the “beginner cards” from 699 euros can be had at a reasonable price. So it’s time for us to investigate these speculations.

After the first announcement of the GeForce RTX – 30 – series and one was a rush for the cards – two years after the start of the previous generation – spread into partly justified, partly unjustified disillusionment. The GeForce RTX 3080 offers compared to the GeForce RTX 2080 a significant leap in performance. If you want to switch from an older generation, you will be happy with at least double the line.

The GeForce RTX 3090 it is a little more difficult. More than twice as expensive, it “only” offers a plus of up to 20% compared to the GeForce RTX 3080, but it is the fastest GeForce card on the market, but the titan bonus of the workstation driver is withheld.

What is usually held up to the two top models, however, is the higher consumption. More than 320 W are always independent of manufacturer and model and this is clearly more than before. Accordingly, much is concentrated in a negative way on consumption.

Our previous tests of the GeForce RTX – 30-Series:

  • New details: Amps and RTX – 30 – Series Deep Dive
  • NVIDIA turns the ampere screw: The GeForce RTX 3080 Founders Edition in the test
  • First custom model: Gigabyte GeForce RTX 3080 Eagle OC 10 G in the test
  • Damn quiet under load: MSI GeForce RTX 3080 Gaming X Trio G in the test
  • Little GeForce for a high surcharge: Gigabyte GeForce RTX 3090 Gaming in the test

With the TUF Gaming GeForce RTX 3080 OC let’s look at the mid-range interpretation of the GeForce RTX 3080 from ASUS. There is another ROG Strix variant, which is located above TUF Gaming.

For all GeForce RTX 3080 is identical the structure of the GA 102 – GPU. 8 are used. 704 FP 32 – and 4. 352 INT 32 – arithmetic units. Added to this are 272 Tensor Cores and 100 RT Cores. The basic clock is with 1. 440 MHz also identical. The GPU of the ASUS TUF Gaming GeForce RTX 3080 OC in gaming mode should be boosted 1. 785 MHz come, in OC mode it is 1. 815 MHz. The memory continues to work with 1. 188 MHz and comes on 320 Bit wide memory interface to a memory bandwidth of 760 GB / s. ASUS raises the power limit for an OC model from 320 on 340 W an.

We tested the card in gaming mode. ASUS also offers the option of operating the card via BIOS in Performance or Quiet mode. However, this has less of an impact on the performance than on the fan control.

Software modes

OC Mode 1.815 MHz 364 W
Gaming Mode 1.785 MHz 340 W
Silent Mode 1. 755 MHz 316 W

After the first tests, we decided not to run the benchmarks for both modes. If anything, we are talking about a difference of a few mega hearts.

The GeForce RTX 3080 in the Founders Edition of NVIDIA offers a power limit of 320 W. Almost all custom models already put a shovel on it – including ASUS with the TUF Gaming GeForce RTX 3080 OC. By default they are 340 W, the power limit can also be set to 375 Increase W.
