AMD Radeon RX 590 vs NVIDIA GeForce GTX 1660 Ti Mobile

The AMD Radeon RX 590 is a desktop graphics card that launched in Q4 2018 with a MSRP of $279. It is built on the GCN 4.0 GPU microarchitecture (codename Polaris 30) and is manufactured on a 12 nm process.

Memory

The RX 590 has 8 GB of GDDR5 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 256 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 590 includes 2,304 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,469 MHz and can dynamically boost its clock speed up to 1,545 MHz. Complementing the processing units are 144 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The RX 590 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 175 W.

Benchmark Performance & Value

The RX 590 has the 100th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 22.31% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 23,362.5 score and $279 launch price (MSRP) gives it a performance per dollar of 83.74. This is the 32nd best in value for the 3DMark 11 Performance GPU benchmark.
