In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce RTX 3090 Asus ROG Strix Gaming OC 24GB are noticeably better than the Nvidia GeForce RTX 2080 Super 8GB.

The RTX 2080 has a 240 MHz higher core clock speed than the RTX 3090, but the RTX 3090 has 160 more Texture Mapping Units than the RTX 2080. As a result, the RTX 3090 exhibits a 187.2 GTexel/s better Texture Fill Rate than the RTX 2080. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RTX 2080 has a 240 MHz higher core clock speed than the RTX 3090, but the RTX 3090 has 32 more Render Output Units than the RTX 2080. As a result, the RTX 3090 exhibits a 29.8 GPixel/s better Pixel Fill Rate than the RTX 2080. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RTX 3090 was released over a year more recently than the RTX 2080, and so the RTX 3090 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the RTX 2080.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The RTX 3090 has 16384 MB more video memory than the RTX 2080, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the RTX 2080 has superior memory performance.

The RTX 2080 has 496.6 GB/sec greater memory bandwidth than the RTX 3090, which means that the memory performance of the RTX 2080 is massively better than the RTX 3090.

The GeForce RTX 3090 Asus ROG Strix Gaming OC 24GB has 10496 Shader Processing Units and the GeForce RTX 2080 Super 8GB has 3072. However, the actual shader performance of the RTX 3090 is 18106 and the actual shader performance of the RTX 2080 is 5576. The RTX 3090 having 12530 better shader performance is not particularly notable, as altogether the RTX 2080 performs better when taking into account other relevant data.

The RTX 3090 transistor size technology is 4 nm (nanometers) smaller than the RTX 2080. This means that the RTX 3090 is expected to run very slightly cooler and achieve higher clock frequencies than the RTX 2080.

The GeForce RTX 3090 Asus ROG Strix Gaming OC 24GB requires 350 Watts to run and the GeForce RTX 2080 Super 8GB requires 215 Watts. We would recommend a PSU with at least 750 Watts for the RTX 3090 and a PSU with at least 600 Watts for the RTX 2080. The RTX 3090 requires 135 Watts more than the RTX 2080 to run. The difference is significant enough that the RTX 3090 may have an adverse affect on your yearly electricity bills in comparison to the RTX 2080.

GPU Mini Review

Mini ReviewOverview The GeForce RTX 3090 Asus ROG Strix Gaming OC 24GB is the top RTX 30 Series graphics card and considered an Enthusiast graphics card based on the Ampere architecture. Architecture The Ampere architecture represents a process shrink down to 7nm compared to 12nm Turing. The Ampere architecture provides the world's next consumer support for real-time ray-tracing technology, or RTX. GPU It equips a GPU Codenamed Ampere GA102 which has 5120 Shader Processing Units, 320 TMUs, and 96 ROPs. The central unit runs at 1410MHz and goes up to 1725MHz in Boost mode. It also has 610 Tensor Cores for AI purposes and 72 RT Cores for real-time ray-tracing. Memory The GPU accesses a 24GB frame buffer of second-gen GDDR6X memory through a 384-bit memory interface, while the Memory clock operates at 1750MHz, or 14GHz effective. Power Consumption With a rated board TDP of 350W, it requires at least a 750W PSU with three 8-pin power connectors. System Suggestions The GeForce RTX 3090 Asus ROG Strix Gaming OC 24GB is best suited for resolutions up to and including 3840x2160.
