About the NVIDIA GeForce RTX 5080 GPU

The NVIDIA GeForce RTX 5080 is a desktop graphics card that launched in Q1 2025 with a MSRP of $999. It is built on the Blackwell 2.0 GPU microarchitecture (codename GB203) and is manufactured on a 5 nm process.

Memory

The RTX 5080 has 16 GB of GDDR7 memory, with a 1,875 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 960 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 5080 includes 10,752 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,295 MHz and can dynamically boost its clock speed up to 2,617 MHz. Complementing the processing units are 336 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 336 tensor cores optimized for AI-accelerated workloads and 84 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RTX 5080 occupies 2 PCIe expansion slots. It supports HDMI 2.1b, DisplayPort 2.1b display connections. NVIDIA recommends a power supply of at least 750 W to handle the GPU's thermal design power (TDP) of 360 W.

Benchmark Performance & Value

The RTX 5080 has the 3rd best 3DMark 11 Performance GPU score among the 567 benchmarked GPUs in our database. It achieves 77.20% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090. Its 100,190 score and $999 launch price (MSRP) gives it a performance per dollar of 100.29. This is the 23rd best in value for the 3DMark 11 Performance GPU benchmark.

About the AMD Radeon RX 6600 GPU

The AMD Radeon RX 6600 is a desktop graphics card that launched in Q4 2021 with a MSRP of $329. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 23) and is manufactured on a 7 nm process.

Memory

The RX 6600 has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 224 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 RX 6600 includes 1,792 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,626 MHz and can dynamically boost its clock speed up to 2,491 MHz. It usually operates at 2,044 MHz during typical gaming workloads. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 28 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 6600 occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 132 W.

Benchmark Performance & Value

The RX 6600 has the 85th best 3DMark 11 Performance GPU score among the 567 benchmarked GPUs in our database. It achieves 24.48% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090. Its 31,774 score and $329 launch price (MSRP) gives it a performance per dollar of 96.58. This is the 27th best in value for the 3DMark 11 Performance GPU benchmark.
