AMD today launched the Radeon RX 6600, the new entry-level model in the company’s RDNA2 based desktop graphics cards. The RX 6600 is priced at $329 and will compete against the Nvidia RTX 3060 that has the same MSRP.
The RX 6600 features the same GPU die as the more expensive 6600 XT but with 28 compute units enabled instead of the 32 on the XT model. The 6600 is also clocked lower at 2491MHz for the boost clock and 2044MHz ‘game clock’. This has resulted in 8.93 TFLOPs peak single precision performance compared to the 10.6 TFLOPs of the 6600 XT.
Both graphics cards use 8GB of GDDR6 memory, however, the 6600 is slightly slower as it’s rated at 14Gbps as opposed to 16Gbps on the 6600 XT with a memory bandwidth of 224GB/s compared to 256GB/s. Both have the same 32MB of high speed Infinity Cache.
Unfortunately, like the 6600 XT, the 6600 also uses the slower bus speed of PCIe 4.0 x8 unlike the PCIe 4.0 x16 used on the higher-end Radeon cards. This could cause performance bottlenecks in some applications.
The 6600 has a lower power rating compared to the 6600 XT at just 132W versus 160W.
The RX 6600 will not have a reference card from AMD. Instead, it will be available only through board partners, including ASRock, ASUS, Gigabyte, MSI, PowerColor, SAPPHIRE, XFX and Yeston. The card is available for purchase starting today.
