Mobile Radeon RX 7800M debuts in external GPU unit, clears 60fps in Wukong

[Daniel Sims]

In brief: One-Netbook's newly unveiled second-generation external GPU is the first known product featuring AMD's Radeon RX 7800M mobile GPU. Internal benchmarks suggest that the chip could put high-end gaming performance within reach of connected handheld gaming PCs, low-end laptops, or mini PCs.

Laptop and mini PC vendor One-Netbook will soon open an Indiegogo campaign for the successor to the OneXGPU. The new external graphics card enclosure features AMD's previously unrevealed Radeon RX 7800M.

For $760, the original OneXGPU provides low-end systems like handheld PCs, mini PCs, and laptops with respectable mid-range gaming performance through its RX 7600M XT. It also famously includes extra M.2 NVMe storage.

According to the specs for the OneXGPU 2, the RX 7800M nearly doubles the number of compute units from 32 to 60 and increases GDDR6 video memory from 8 GB to 12 GB. One-Netbook's video shows the high-end mobile GPU running the Black Myth: Wukong benchmark comfortably above 60fps at 3,440 x 1,440 resolution using "high" graphics settings while connected to the company's OneXPlayer X1 mini PC.

However, viewers might want to take the results with a pinch of salt until third-party reviewers gain access to the final product. In TechSpot's analysis of the same benchmark tool, the desktop RX 7800 XT only managed an average of 57fps at 2,560 x 1,440 resolution on the high preset.

One-Netbook also claims that the 7800M can stay over 60fps in the 2018 God of War game at 2,560 x 1,600 and in Red Dead Redemption 2 at 1,920 x 1,200 with maximum graphics settings. The latter title's top-end specs are infamously demanding.

Like its predecessor, the OneXGPU 2 supports plenty of connectivity options. It features USB 4.0, Oculink, HDMI 2.1, M.2, two DisplayPort 2.0 outputs, and more, enabling users to connect up to three screens. Launch and price details are forthcoming, but the company confirmed a 30-percent-off early-bird deal.

External GPUs have typically come in the form of bulky enclosures for used desktop parts, but companies like GPD and One-Netbook now offer travel-sized models based on laptop hardware. For example, a 7600M-based example from Hi GT Cube includes 100W charging functionality as a bonus.

Meanwhile, users can expect the 7800M to offer a good middle ground between the existing 7600M and the much more expensive RX 7900M when it eventually appears in high-end gaming laptops.

Now that's better. It's not the 7900m, but its a LOT better then the e-waste that is the 7600m. Being able to use any laptop with it is a huge bonus.

That being said, would prefer a more professional look, with more useful ports, as opposed to the "gamur" aesthetic.

Seems fishy to me . If it were true AMD would take the lead in GPUs . I doubt this is the case .

Only thing fishy thing here is Techspot’s testing methods. This game was benched with all the Ngreedia GPUs using DLSS and Frame Generators. The the Radeons were benched without either.

I notice how the Nvidia fanboy crowd stay super silent when the RTX 4090 in that game without DLSS and Frame Gen only hit playable frame rates with the resolution pegged back to a little more than 720P.

Remember that in all other titles bar this single outlier, AMD do have competitive cards: RX 7900XTX as an example trades blows with the RTX 4080S. Radeon is slightly ahead in raster, and slightly behind it with RT.

Again, except in this particular game that is clearly given huge bias to Nvidia technology. The mobile GPU is also quite performant if true.

But like everything AMD, it won’t sell because every tech site under the sun always recommends spending the extra few hundred to “upgrade” to Nvidia, and they bash AMD hard. Very hard.

The current AMD GPUs lose in terms of power efficiency . Draw 20% more than NVidia counterparts . Also driver issues . But that result above is quite fishy - outright scam . Maybe used tricks as upscaling and frame generation . It cant show the raw performance .

 

[hahahanoobs]

I stopped reading after $760.
That's just nuts.

When the hard performance numbers are thrown out, your (predictable) position then switches to:

- Power use
- Driver problems

Radeon power efficiency isn’t terrible, within 10% either way on Nvidia counterparts. Unlike the 99% out there, I use Radeon and can say from my experience the driver issues seem to be heavily overblown.

I can’t believe we’re still kicking the AMD driver stability can down the road literally 5-7 years later.

no , its 20% and even worse . You remember the missing sun in Starfield ? Subpar upscaler , Anti lag failure/flop and etc.

gaming
RX 7800XT -250W , 4.5% faster
RTX 4070 - 200W

Do you realize what this product is? Better question, when is the last time you priced out a thunderbolt dock with 100w power delivery? Hint: they're not cheap. A normal dock will range anywhere from $250-400 depending on ports and features. This has a GPU thrown on top, a 7700xt, which retails for $400 on its own.

So I'm curious why you think that the $760 asking price is "unreasonable"?

See it has mandatory rbg lights. Yes pricing is steep, but this is just the beginning. In a number of years won't even need a direct connect to your laptop, tablet, So whole ARM devices ,plus very efficient from AMD, Intel etc will make sense.
Many transient people as more renting etc , apartment life. I can see this and a console being all many need

Plus I keep mentioning it , this allows super easy casting to big screen TVs, or makes sense to buy a super premium screen , that can be used year after year with externals

 

[okeribok]

But does it support ROCm?
