AMD Radeon HD 7870 (GHz Edition) vs AMD Radeon RX 570

The AMD Radeon RX 570 is a desktop graphics card that launched in Q2 2017 with a MSRP of $169. It is built on the GCN 4.0 GPU microarchitecture (codename Polaris 20) and is manufactured on a 14 nm process.

Memory

The RX 570 has 4 GB of GDDR5 memory, with a 1,750 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 224 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 570 includes 2,048 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,168 MHz and can dynamically boost its clock speed up to 1,244 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 570 occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0b, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 150 W.

Benchmark Performance & Value

The RX 570 has the 117th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 18.11% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 18,967 score and $169 launch price (MSRP) gives it a performance per dollar of 112.23. This is the 12th best in value for the 3DMark 11 Performance GPU benchmark.
