Steam Deck Specs Boost

A post on twitter notes that there was an error in Valve's Steam Deck announcement (thanks PC Gamer). It seems the listing of dual-channel RAM support should have been quad-channel. This has now been corrected, and here's what the specifications now report:

Processor AMD APU
CPU: Zen 2 4c/8t, 2.4-3.5GHz (up to 448 GFlops FP32)
GPU: 8 RDNA 2 CUs, 1.0-1.6GHz (up to 1.6 TFlops FP32)
APU power: 4-15W
RAM 16 GB LPDDR5 on-board RAM (5500 MT/s quad 32-bit channels)
Storage 64 GB eMMC (PCIe Gen 2 x1)
256 GB NVMe SSD (PCIe Gen 3 x4)
512 GB high-speed NVMe SSD (PCIe Gen 3 x4)

On phones, especially on iPhones, the pixel dimensions tend to be greater than desktop displays. The 11 Pro Max and Xs Max, for example, have a render pixel size of 1242 x 2688, which is larger than 2K resolution. If that is present in the Dock, then people are in for ultra-high video quality. It might be even better watching a film and TV shows on the Dock than a phone and more comfortable to hold than a bulky tablet.
Curious.....do you watch more videos on your phone than other devices? I don't enjoy the compact format and would rather watch shows/movies in a couch/television environment. I watch some things on my tablet when I'm getting ready in the morning or out and about....but for relaxing entertainment, I def prefer a couch/television.
I have a television, but I never watch it. I've stopped watching television since 2005. I prefer the Internet as I'm not too fond of force-fed television content. I like the freedom to view what I want when I want it.

So outside of my Desktop, I watch videos on my phone despite having a tablet somewhere in the house. The tablet is uncomfortable to hold with its bizarre triangular shaped stand. It wobbles on anything other than a hard surface, making it useless for bedtime viewing. I could see the Dock being an entertainment viewing upgrade over the phone. Bigger display, and it looks as comfortable to hold as a phone. I'm in no rush to buy a Dock, but when the madness dies down, I'll likely pick one up for gaming, YouTube, movies, and watching my favorite TV shows. I'm looking at the Dock as more of an entertainment upgrade to the phone. I wonder if the Dock can run Android apps?

No problem. While I'm not particularly interested in buying one the underlying tech is very interesting to me. I've hoped for improved integrated graphics for lower power devices for a long time.

I've got a GTX 650 ti boost (a fair bit faster than regular, but still close enough) in a spare box which does 1920x1200 fine (just gotta drop settings mostly for vram) so I'd bet the Steam Deck ought to do 720/780p really well.

What Intel chip does the CPU equate to?
What Nvidia card does the GPU equate to?

GPU is basically impossible to figure out without more information from Valve, because RNDA2 has roughly a 1/3 increase in ROPs over Vega (AMD's prior integrated solutions), but we don't know shader units or TMU values. The mobile Vega parts also have had higher clock speeds than what Valve is advertising so there isn't really a great comparison there either. Memory bandwidth for DDR4 is about 51GB/s, LPDDR4x is about 68GB/s whereas the LPDDR5 should be about 88GB/s so this will also come into play in a big way. Taking a guess based on the generic things we can extrapolate I'd say the performance should be similar to the Ryzen 7 4800U +20% which would be around the GTX 650 ti.

CPU side is much simpler to guess as it should be about the same performance as the AMD Ryzen 3 PRO 4450U which has a rough equivalent of the Intel i3-10100f (at least in geekbench, finding benchmarks was proving to be difficult).

Thank you. Most informative. 🙂

I'd imagine a GTX 650 ti equivalent is more than enough for a 720p display.

I don't think there's such a thing as "high-speed NVMe". I believe they are just referring to a higher-speed SSD. Of course any SSD using NVMe is already super fast (I have old SATA SSDs and their speeds are just fine for me).

Yep, it's probably something like the 256GB goes 1000MB/s and the 512GB goes 2500MB/s.

Obviously it won't make a huge difference except during load times.....but I'm curious if it will make any perceptible difference.
256 GB NVMe SSD (PCIe Gen 3 x4)
512 GB high-speed NVMe SSD (PCIe Gen 3 x4)
My quick google-fu isn't giving me any specific tech specs for "high-speed" NVMe other than enterprise gear....which seems odd for a consumer hand held.

Maybe I’m getting old but pretty crazy that TFLOPS rating we’re seeing with a 15 watt chip. Only shame is that it’s Zen 2, because Zen 3 is a lot faster for gaming.

LPDDR5 is pretty fast, running in quad-channel is a great way to get a further boost. Definitely will help the APU.
It's going to be really interesting to see how it'll run native Linux games without any of the overhead of Proton.
And there's some pretty demanding games available natively on Linux.
I expect Phoronix.com will have some must-see benchmarks to show when the Deck ships.

I'm sure we'll hear, but given that it's aiming for 720p, should be fine.

I'm sure it's fine too. I was just curious what the CPU and GPU equates to so I understand the context.

This shouldn't actually surprise anyone since that's how LPDDR works (note 32bit channels is specifically mentioned, and standard DDR is 64bit).

Designing and manufacturing for quad channel ram probably did not add much to the cost and I'm guessing it would improve performance anywhere from 5 to 10%, probably closer to 5.
