AMD Radeon HD 7870 (GHz Edition) vs NVIDIA GeForce RTX 3080 Ti

The NVIDIA GeForce RTX 3080 Ti is a desktop graphics card that launched in Q2 2021 with a MSRP of $1,199. It is built on the Ampere GPU microarchitecture (codename GA102) and is manufactured on a 8 nm process.

Memory

The RTX 3080 Ti has 12 GB of GDDR6X memory, with a 1,188 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 912.4 Gb/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 3080 Ti includes 10,240 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,365 MHz and can dynamically boost its clock speed up to 1,665 MHz. Complementing the processing units are 320 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 320 tensor cores optimized for AI-accelerated workloads and 80 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX 3080 Ti occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 750 W to handle the GPU's thermal design power (TDP) of 350 W.

Benchmark Performance & Value

The RTX 3080 Ti has the 16th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 58.30% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 60,980 score and $1,199 launch price (MSRP) gives it a performance per dollar of 50.86. This is the 64th best in value for the 3DMark 11 Performance GPU benchmark.
