Valve has updated the Steam Deck specifications to properly report the really impressive memory specification of the hand. It was first observed with dual-channel RAM, and now the updated specification correctly lists four-channel 32-bit LPDDR5 with speeds of up to 5,500 MT / s.
The gross speed that Valve offers for its handheld console, 5,500 MT / s, has not really changed since it was announced, but, as indicated by Twitter user Locuza, something did not add to the specifications Initial LPDDR5 listed by Valve.
Now a debate and curiosity is resolved: Van Gogh, who is used by Valve's Steam Deck, has 4 UMCs. Expected 4x 16 bits (a memory channel under LPDDR5 has a width of 16 bits). The official specification claimed 5.5 Gbps (dual channel), which made no sense to me. Fixed pic.twitter.com/orgzMKJldEJuly 19, 2021
The Steam Deck first appeared with dual-channel LPDDR5, however, which has now been corrected to 32-bit four-channel LPDDR5. An important distinction, as it confirms that Steam Deck has a lot of bandwidth in relation to the expected performance of the GPU.
Memory bandwidth is especially important for a device like the Steam Deck, and this is due to the choice of the Valve chip.
The Steam Deck works with an AMD APU (a slice of silicon that contains CPU and GPU) and, if there’s one thing that’s incredibly useful for an APU, it’s the memory bandwidth. This is because both the CPU and GPU share access to the same memory pool, doubling the memory component's requirements over a conventional PC configuration.
A desktop PC with a discrete graphics card doesn't have to worry the same way. While it is still important to have a wide amount of memory bandwidth available for key components, it shares the load in two dedicated memory groups, today it is the most common DDR4 memory for the CPU and GDDR6 memory for the GPU.
So are there still more reasons to get excited about the Steam Deck? In fact, Valve's handheld device is becoming an exciting device, and after that fix, it's even better considered.
