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.
About the AMD Radeon HD 7770 (GHz Edition) GPU
The AMD Radeon HD 7770 (GHz Edition) is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $159. It is built on the GCN 1.0 GPU microarchitecture (codename Cape Verde) and is manufactured on a 28 nm process.
Memory
The HD 7770 has 1,024 MB of GDDR5 memory, with a 1,125 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 72 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 7770 includes 640 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,000 MHz. Complementing the processing units are 40 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The HD 7770 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, mini-DisplayPort 1.2 display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 80 W.
Benchmark Performance & Value
The HD 7770 has the 298th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.96% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 3,098 score and $159 launch price (MSRP) gives it a performance per dollar of 19.48. This is the 87th best in value for the 3DMark 11 Performance GPU benchmark.
