AMD Radeon RX 5700 vs AMD Radeon HD 7870 (GHz Edition)

The AMD Radeon RX 5700 is a desktop graphics card that launched in Q3 2019 with a MSRP of $349. It is built on the RDNA 1.0 GPU microarchitecture (codename Navi 10) and is manufactured on a 7 nm process.

Memory

The RX 5700 has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 448 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 5700 includes 2,304 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,465 MHz and can dynamically boost its clock speed up to 1,725 MHz. It usually operates at 1,625 MHz during typical gaming workloads. Complementing the processing units are 144 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The RX 5700 occupies 2 PCIe expansion slots. It supports 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 180 W.

Benchmark Performance & Value

The RX 5700 has the 69th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 30.09% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 31,470 score and $349 launch price (MSRP) gives it a performance per dollar of 90.17. This is the 25th best in value for the 3DMark 11 Performance GPU benchmark.
