AMD Radeon HD 6870 vs AMD Radeon RX 470

The AMD Radeon RX 470 is a desktop graphics card that launched in Q3 2016 with a MSRP of $179. It is built on the GCN 4.0 GPU microarchitecture (codename Ellesmere) and is manufactured on a 14 nm process.

Memory

The RX 470 has 4 GB of GDDR5 memory, with a 1,650 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 211.2 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 470 includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 926 MHz and can dynamically boost its clock speed up to 1,206 MHz. Complementing the processing units are 128 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The RX 470 occupies 2 PCIe expansion slots. It supports HDMI 2.0b, 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 120 W.

Benchmark Performance & Value

The RX 470 has the 126th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 16.85% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 17,624.5 score and $179 launch price (MSRP) gives it a performance per dollar of 98.46. This is the 16th best in value for the 3DMark 11 Performance GPU benchmark.
