The 4080 12GB has a 192-bit memory bus width, which seems extraordinarily odd for a premium product. Despite sharing the same model name, the 16GB 4080 is going to be much faster than the 12GB variant, in both raw performance and even with memory bandwidth. While the RTX 4090 is the first Ada Lovelace GeForce to release, NVIDIA’s already announced the next two: RTX 4080 16GB, and RTX 4080 12GB. RTX 3000 = Ampere RTX 4000 = Ada Lovelace NVIDIA’s GeForce Gaming & Creator GPU Lineup
We haven’t done thorough temperature testing yet, but we have tested the RTX 4090 enough to see that it draws an additional 100W over the 3090 (650W total) during a 3DMark Fire Strike Ultra test. The latest model has a larger fan, and at the same time reduces the number of blades. With regards to the RTX 4090’s cooler, the design remains similar to that seen on the last generation with the RTX 3090, but under-the-hood improvements have benefited temperatures. We’ll explore this with our upcoming full creator performance look.īefore jumping into a look at rendering performance with NVIDIA’s newest flagship, let’s take a look at the hardware, with NVIDIA’s Founder Edition:
Intriguingly, NVIDIA offers dual encoders on-board, which it claims will quite literally halve encode times. Also, Intel was first to market with an AV1 accelerated GPU encoder, and NVIDIA wasn’t far behind, as Ada Lovelace packs one in, as well. Other features worth noting is Shader Execution Reordering, which further improves ray tracing performance, including in games, where one such example shows a 44% bump in Cyberpunk 2077. On the ray tracing core side, Ada Lovelace introduces the 3rd-gen implementation, which promises (and largely delivers) a 2x performance boost over the Ampere generation. In creation, these accelerate things like denoising, while for gaming use, they’re taken advantage of for upscaling through DLSS – which is now at version 3. There’s only so much time in the day, and only so much benchmarking that can get done in any given day.Īs covered before, the Ada Lovelace generation brings 4th-gen Tensor cores and improved Optical Flow to the table. While this article revolves around rendering performance in 3D design software, our future looks are going to expand the creator angle to involve encoding, photogrammetry, AI, and math workloads, and naturally, gaming tests are in store, as well.
