Steam Deck Specs: OLED vs LCD, Battery Life, Storage and Screen Size

Summary: The Steam Deck specs that matter: the current Steam Deck OLED has a 7.4-inch 90Hz HDR OLED screen, 16GB of LPDDR5 memory, a 50Wh battery and 512GB or 1TB of storage, all driven by AMD's custom Zen 2 and RDNA 2 chip. The older Steam Deck LCD used the same chip design with a 7-inch 60Hz screen and a 40Wh battery, and it is now sold only refurbished. New OLED models cost $789 and $949 in the US after Valve's May 2026 price rise.

• Same processor family on both models, so game performance is close.
• The OLED wins on screen, Steam Deck OLED battery life, Wi-Fi and weight.
• Storage can be expanded with a microSD card on every model.
• Valve has not announced a Steam Deck 2.

Steam Deck Specs at a Glance

Here are the full Steam Deck specs for both versions side by side. The OLED is the only model Valve still makes; the Steam Deck LCD specs matter if you are buying refurbished or second hand.

Steam Deck OLED Specs vs LCD Specs

The Steam Deck OLED specs look like a small update on paper, but they change how the device feels. The chip is the same AMD design shrunk from 7nm to 6nm, so it runs cooler and draws less power rather than running games much faster. The memory is quicker, the fan is quieter and the Wi-Fi moves up to 6E, which helps with downloads and streaming from a PC.

The Steam Deck LCD specs are still fine for most games, which is why refurbished LCD units remain popular. If budget matters more than the screen, a refurbished LCD at under $400 is the cheapest Valve-backed way into PC handheld gaming.

Steam Deck Screen Size

The Steam Deck screen size is 7 inches on the LCD and 7.4 inches on the OLED, both at 1280x800. The OLED fits the larger Steam Deck OLED screen size into a body the same size by trimming the bezels, and adds HDR, deeper blacks and a 90Hz refresh rate. The Steam Deck OLED screen size is also the main reason people upgrade: colours and contrast are a clear step up, even though the resolution is unchanged.

Steam Deck Battery Life

Valve rates Steam Deck battery life at roughly 3 to 12 hours for the OLED and 2 to 8 hours for the LCD. The real figure depends on the game. Demanding 3D titles at full settings drain an OLED in about three hours, while 2D games, streaming or a 30fps cap can stretch past eight. Steam Deck OLED battery life benefits from both the bigger 50Wh cell and the more efficient chip and screen.

Steam Deck charger specs are the same for both: a 45W USB-C Power Delivery charger. Any good 45W USB-C PD charger works, which is handy when travelling.

Steam Deck Storage and Upgrades

Steam Deck storage comes in 512GB or 1TB on the OLED. Every model also has a microSD slot, so Steam Deck expandable storage is as simple as adding a fast card, and many players keep their library split between the SSD and a 512GB or 1TB card.

Can you upgrade Steam Deck storage internally? Yes. The internal drive is a standard M.2 2230 NVMe SSD, and a Steam Deck storage upgrade is a common DIY job with published repair guides, though opening the device is at your own risk. For Steam Deck external storage, USB-C drives and docks work for moving files or running smaller games.

Steam Deck vs Switch 2 and Legion Go Specs

Comparing Switch 2 vs Steam Deck specs, Nintendo's console has a larger 7.9-inch 1080p screen at up to 120Hz and runs Nintendo's own library, while the Steam Deck runs your Steam games. On Steam Deck vs Legion Go specs, Lenovo's handheld has a bigger 8.8-inch high-resolution screen and a newer AMD chip, at the cost of weight and battery life. Searches for "switch 2 vs steam deck specs" and "steam deck vs legion go specs" usually come down to which game library you want.

Steam Deck 2 Specs: What Is Known

Nothing official. Valve has not announced a Steam Deck 2, so any Steam Deck 2 specs you see are speculation. Valve has said in the past that it wants a meaningful performance jump without hurting battery life before releasing a successor, and memory shortages pushed up prices across 2026. Until there is an announcement, the OLED is the current model.
