XFX Radeon RX 6600 Speedster SWFT 210

Not the fastest card on the block

AMD’S RX 6600 GPU may be the end of the line for desktop RDNA2 graphics cards. AMD also has APUs with RDNA2 graphics in the works, and Samsung’s upcoming Exynos smartphone chip will put RDNA2 into mobile devices. We’d be hardpressed to name one good reason why a smartphone needs ray tracing hardware, but that’s a topic for another day.

Building off the same Navi 23 GPU that powers the RX 6600 XT, the vanilla 6600 comes with 28 of the potential 32 CUs enabled. That’s a relatively small reduction in the number of functional units, but AMD also trims clocks by anywhere from 100–300 MHz, depending on GPU temperatures, power use, and other factors. The GDDR6 memory also gets a speed reduction from 16Gbps down to 14Gbps.
