About the AMD Radeon RX 6400 GPU

The AMD Radeon RX 6400 is a desktop graphics card that launched in Q2 2022 with a MSRP of $159. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 24) and is manufactured on a 6 nm process.

Memory

The RX 6400 has 4 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 128 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 6400 includes 768 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,923 MHz and can dynamically boost its clock speed up to 2,321 MHz. It usually operates at 2,039 MHz during typical gaming workloads. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing. Additionally, the GPU features 12 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 6400 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports HDMI 2.1, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 53 W.

About the AMD Radeon RX 550X GPU

The AMD Radeon RX 550X is an end-of-life desktop graphics card that released in Q4 2018. It is built on the GCN 4.0 GPU microarchitecture (codename Lexa) and is manufactured on a 14 nm process.

Memory

The RX 550X has 4 GB of GDDR5 memory, with a 1,500 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 96 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 550X includes 512 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,100 MHz and can dynamically boost its clock speed up to 1,183 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The RX 550X occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0b, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 50 W.

Benchmark Performance

The RX 550X has the 239th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.11% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
