AMD launched the Radeon RX 6600 XT towards the end of last month for $379 as a 1080p gaming card. The GPU is based on the full Navi 23 die which means the company could still release a cut-down version of the chip allegedly called the RX 6600. This cut-down GPU is said to feature four fewer Compute Units (CUs) with 1,792 stream processors. And while the RX 6600 hasn't been launched for desktop gaming yet, it already exists for laptops and notebooks as well as in the form of a workstation GPU called the Radeon PRO W6600.
igor'sLAB was able to get its hands on the latter and tested the card to see how the yet-to-be-released Radeon RX 6600 could potentially perform against other graphics cards, and especially Nvidia's GeForce RTX 3060.
Workstation cards are mostly the same hardware-wise with a few tweaks here and there. It's the drivers that make the most difference. In order to emulate this, the W6600's memory was overclocked from 14Gbps to match that of the 6600 XT's at 16Gbps. This increased the bandwidth of the emulated RX 6600 to 256GB/s. Alongside this, the latest Radeon software 21.8.1 driver was installed which is said to be optimized for the Navi 23 GPU.
A total of nine games were tested at the highest available settings. They are:
- Borderlands 3
- Ghost Recon Breakpoint
- Horizon Zero Dawn
- Marvel's Avengers
- Metro Exodus Enhanced Edition
- Necromunda: Hired Gun
- Shadow of the Tomb Raider
- Watch Dogs: Legion
- Wolfenstein Youngblood
The images below show how the emulated RX 6600 performs on average in these titles and also relative to its primary competitor, the RTX 3060:
The power consumption, as well as the efficiency exhibited by the GPU, relative to the other cards has been measured too:
Just like the bigger Navi 23 GPU, the emulated RX 6600 also seems exceptionally efficient when it comes to power draw. In fact, a recent report suggested the RX 6600 XT may be the most efficient ethereum mining GPU from this generation of cards.
