Nvidia is putting desktop-caliber GTX 980 GPUs in laptops

Maxwell GM204 DIE 3D V17 Final 

When Nvidia launched the 980M last October, it claimed that the laptop GPU could hit 75-80% of the performance of the desktop card. That was impressive compared to the mobile GPUs of a generation or two back, but not as impressive as what Nvidia’s done now: fit the entire, uncompromised desktop 980 GPU into gaming laptops. Starting early October with six laptops from MSI, Gigabyte, Asus and Clevo, the GTX 980 is making its way into laptops, with all 2048 CUDA cores intact. And it’s overclockable.
To show off the full-on 980 doing its thing in laptops, Nvidia demoed several laptops side-by-side with desktop machines to compare benchmarks. In Shadow of Mordor, Tomb Raider, and a couple other benchmarks, the laptop system was able to turn in nearly identical scores—at worst, about 5% off what the desktop machine delivered. In those cases, it wasn’t even quite a fair fight, since a laptop CPU was up against a more powerful desktop CPU. Some of the laptops were actually equipped with desktop parts and delivered dead even performance. In one case, 3DMark actually turned in identical scores down to the point.
The GTX 980 will be able to deliver 7 Gbps of memory bandwidth compared to the 980M’s 5 Gbps. Whereas the mobile 980s previously only had 3 phase PSUs, the new cards will be outfitted with 4-8 phase power supplies, which will vary by laptop. Every system that ships with a 980 will have a custom-tuned fan curve to keep the card cool, but it’ll also ship with some sort of overclocking tool, like MSI Afterburner or Gigabyte’s OC Guru.
Nvidia 980 Laptops
How overclockable the 980 will be will naturally vary from laptop to laptop, as different systems will have different thermal constraints. You can bet that the Asus GX700, that watercooled beast of a laptop we wrote about last week, will be able to push the 980 to its limits.
All of this performance requires the laptop be plugged into AC power, however. Without the extra juice from the wall socket, the 980 will deliver roughly equal performance to the 980M.
We don’t have pricing information or exact release dates on the laptops launching with the 980, but here are the ones coming in the near future:
  • Asus GX700
  • Clevo P775DM-G
  • Clevo P870DM-G
  • Gigabyte Auros RX7Y4
  • MSI GT72
  • MSI GT80
Nvidia also told us that like with the 980M, there will be SLI configurations of the full-size 980 in laptops, too. That’s likely as much GPU muscle as you’re going to find in a laptop until sometime in 2016, when Nvidia has a new generation of cards to roll out.
