NVIDIA GeForce RTX 3080 Mobile vs NVIDIA GeForce RTX 4090

The NVIDIA GeForce RTX 4090 is a desktop graphics card that launched in Q4 2022 with a MSRP of $1,599. It is built on the Ada Lovelace GPU microarchitecture (codename AD102) and is manufactured on a 5 nm process.

Memory

The RTX 4090 has 24 GB of GDDR6X memory, with a 1,313 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 1.01 Tb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The RTX 4090 includes 16,384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,235 MHz and can dynamically boost its clock speed up to 2,520 MHz. Complementing the processing units are 512 texture mapping units (TMUs) for efficient texture filtering and 176 render output units (ROPs) for pixel processing. Additionally, the GPU features 512 tensor cores optimized for AI-accelerated workloads and 128 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX 4090 is a large graphics card, occupying 3 PCIe 4.0 x16 expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. With a thermal design power (TDP) of 450 W and a large, 3-slot size, it is recommended to use a power supply of 850 W and a case with sufficient space to accommodate the card. Compare your card's model and your case's dimensions to verify compatibility.
