About the AMD Radeon RX 640 GPU
The AMD Radeon RX 640 is a desktop graphics card that launched in Q2 2020. It is built on the GCN 4.0 GPU microarchitecture (codename Polaris 23) and is manufactured on a 14 nm process.
Memory
The RX 640 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 640 includes 640 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,218 MHz and can dynamically boost its clock speed up to 1,218 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 RX 640 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DisplayPort 1.4a, mini-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 640 has the 245th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.00% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the AMD Radeon RX 460 GPU
The AMD Radeon RX 460 is a desktop graphics card that launched in Q3 2016. It is built on the GCN 4.0 GPU microarchitecture (codename Baffin) and is manufactured on a 14 nm process.
Memory
The RX 460 has 2 GB of GDDR5 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 112 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 460 includes 896 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,090 MHz and can dynamically boost its clock speed up to 1,200 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The RX 460 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 75 W.
Benchmark Performance
The RX 460 has the 193rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 8.22% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
