Key Takeaways
1. A Steam Deck prototype was auctioned on eBay for $2,000, despite a listing price of $2,999.99.
2. The prototype, completed in February 2020, featured an experimental AMD ‘Picasso’ APU, which was less powerful than the retail Aerith APU.
3. The Picasso APU provided about half the GPU power of the Aerith, which uses an RDNA 2-based iGPU.
4. The prototype had 8 GB of RAM and 256 GB of storage, while retail Steam Decks have 16 GB of RAM and various storage options (64 GB, 512 GB, 1 TB).
5. The future of the prototype, designated as ‘Engineering Sample 34,’ is uncertain, and it may be showcased again later.
A few years ago, Pierre-Loup Griffais posted images and a short video of some Steam Deck prototypes. Recently, one of these prototypes was auctioned on eBay in the US for a staggering $2,000. It’s important to mention that while the eBay listing indicates the final auction price was $2,999.99, an accepted Best Offer of $2,000 was actually the price paid.
Prototype Details
The images in the listing show that Valve completed this prototype around February 2020, which is about two years before the retail versions hit the market. The Steam Deck officially comes with two APU options: one called Aerith for the LCD models and another named Sephiroth for the OLED versions. However, Engineering Sample 34 shows that Valve was also experimenting with an AMD ‘Picasso’ APU, likely incorporating Zen CPU cores alongside Vega (GCN 5.0) iGPU cores.
Performance Comparison
Pierre-Loup Griffais mentioned that this Picasso APU was only providing “about half” the GPU power of Aerith, which uses an RDNA 2-based iGPU with 8 Compute Units. In comparison, newer APUs such as the Ryzen Z1 Extreme present in the Asus ROG Ally (currently priced at $599.99 on Amazon) come with 12 CUs from AMD’s advanced RDNA 3 architecture. This means that, had this prototype been released as a consumer product, it would have been quickly outdated.
At that time, Valve was also working on the Steam Deck with 8 GB of RAM and 256 GB of storage. In contrast, all the retail units of the Steam Deck come equipped with 16 GB of RAM, and storage options include 64 GB, 512 GB, and 1 TB across both the LCD and OLED models. Where ‘Engineering Sample 34’ will go next is still uncertain, and it remains to be seen if it will appear in public again. Hopefully, we will see this prototype showcased in the future.
