About the AMD Radeon RX 6950 XT GPU

The AMD Radeon RX 6950 XT is a desktop graphics card that launched in Q2 2022 with a MSRP of $1,099. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 21) and is manufactured on a 7 nm process.

Memory

The RX 6950 XT has 16 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 576 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 6950 XT includes 5,120 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,860 MHz and can dynamically boost its clock speed up to 2,310 MHz. It usually operates at 2,100 MHz during typical gaming workloads. Complementing the processing units are 320 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 80 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 6950 XT 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 335 W and a large, 3-slot size, it is recommended to use a power supply of 700 W and a case with sufficient space to accommodate the card. Compare your card's model and your case's dimensions to verify compatibility.

Benchmark Performance & Value

The RX 6950 XT has the 8th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 69.05% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 72,227.5 score and $1,099 launch price (MSRP) gives it a performance per dollar of 65.72. This is the 48th best in value for the 3DMark 11 Performance GPU benchmark.

About the AMD Radeon HD 6450 GPU

The AMD Radeon HD 6450 is an end-of-life desktop graphics card that released in Q2 2011 with a MSRP of $55. It is built on the TeraScale 2 GPU microarchitecture (codename Caicos) and is manufactured on a 40 nm process.

Memory

The HD 6450 has 512 MB of DDR3, GDDR5 memory, with a 500 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 8 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 HD 6450 includes 160 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 625 MHz. Complementing the processing units are 8 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The HD 6450 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, HDMI 1.3a, VGA display connections. AMD recommends a power supply of at least 200 W to handle the GPU's thermal design power (TDP) of 18 W.

Benchmark Performance & Value

The HD 6450 has the 500th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.60% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 623 score and $55 launch price (MSRP) gives it a performance per dollar of 11.33. This is the 96th best in value for the 3DMark 11 Performance GPU benchmark.
