Steam Deck Full Specs Revealed, Features Custom RDNA 2 GPU, Claims 1.6 TFLOPs of Power


The newly-announced Steam Deck features a custom AMD APU, which combines a Zen 2 CPU with an RDNA 2 GPU for seemingly great performance numbers.​

Steam has recently unveiled the long-rumored SteamPal handheld, which is now confirmed to be known as the Steam Deck. Featuring a 7-inch touchscreen with a Nintendo Switch-Esque form factor, the handheld seems to have impressive tech specs for its size.

The Steam Deck comes with an AMD APU which includes a Zen 2 CPU with 4 cores/8 threads operating at a frequency of 2.4 GHz to 3.5 GHz, and a custom GPU. The GPU features 8 RDNA 2 CUs with a variable frequency of 1.0-1.6 GHz, that should put in the ballpark of 1.6 TFLOPs of performance. It has 16 GBs of LPDDR5 RAM, and upto 512 GB of “high-speed” NVMe SSD depending on the variant customers spring for.

While the specs might not seem as impressive judging solely by TFLOPs count, the newer architecture chip and plenty of memory should put the Steam Deck’s hardware ahead of what is possible on Xbox One and PS4. This looks quite promising for now, and it would be interesting to see how Steam manages to sustain peak performance for long durations of time in this small form factor. You can check out the full specs below:
