NVIDIA GeForce RTX 3080: 168% of RTX 2080 SUPER performance in CUDA and OpenCL benchmarks

The first post-announcement benchmark of the GeForce RTX 3080 graphics cards.

NVIDIA GeForce RTX 3080: 168% of RTX 2080 performance

The GeForce RTX 3080 has been put through a number of CUDA and OpenCL tests with the Compubench benchmark suite.

The GeForce RTX 3080 graphics card has been tested using 456.16 drivers. The OpenCL info page reveals its a 10GB variant with 68 Compute Units (Streaming Multiprocessors) and 1710 MHz boost frequency. This is either the Founders Edition model tested by one of the reviewers or a custom variant featuring the same clock speed. The CUDA info page confirms its a 320-bit memory configuration with 19 Gbps modules.

These types of tests are compute oriented and do not illustrate gaming performance at all. Especially when we take all the new hardware to accelerate technologies (such as RTX or DLSS) into account.

NVIDIA RTX 3080 performance

We gathered the data for both CUDA and OpenCL tests. The average for both tests, however, is more or less the same. The RTX 3080 has on average 168% of RTX 2080 SUPER performance and 138-141% performance of the RTX 2080 Ti.
