NVIDIA GeForce GTX 1650 Max-Q vs NVIDIA GeForce GTX 980 vs NVIDIA GeForce GTX 980 SLI (Laptop)

NVIDIA GeForce GTX 1650 Max-Q

NVIDIA GeForce GTX 980

The NVIDIA GeForce GTX 980 is a high-end desktop graphics card based on the second generation Maxwell architecture. The GM204 chip is manufactured in 28 nm at TSMC. Compared to the older GeForce GTX 780Ti, the 980 offers similar performance levels but at reduced average power consumption. The similarly named Nvidia Geforce GTX 980M for notebooks is based on the same chip, but uses less shader cores and slower clock speeds for reduced performance. Since end of 2015, the GTX 980 is also used in laptops (same chip with same clocks and branding).

The Geforce GTX 980 supports a range of unique features like CUDA, 3D Vision, PhysX, GeForce Experience, GameStream, GPU Boost 3.0, Adaptive Vertical-Sync / G-Sync, SLI, DSR, MFAA and Virtual Reality latency improvements.

NVIDIA GeForce GTX 980 SLI (Laptop)

The Nvidia GeForce GTX 980 SLI is a high-end DirectX 12-compatible graphics solution for laptops, consisting of two GeForce GTX 980 cards. Each card has a 28 nm GM204 GPU based on the Maxwell architecture with similar specifications as the desktop GeForce GTX 980. The clocks for the SLI-setup are usually identical to a single GTX 980.

With SLI, each card renders a single frame (AFR mode). Therefore, it may suffer from micro-stuttering in low fps ranges of 30 fps. This happens because of different time-spans between two frames (e.g., irregular delays between sequential frames).

The performance is on a level with the two desktop GTX 980 cards in SLI. Due to the different cooling solutions, the long-term performance may be slightly lower compared to a well cooled desktop, but Nvidia assures there will only be small degrades in performance. As with all SLI combinations, the performance depends on the driver support for the used benchmark and game. In our tests with an MSI GT80S, the 980 SLI was the fastest graphics solution for laptops. The 980M SLI was 17% slower, a single 980 26% slower. Therefore, the 980 SLI for laptops offers enough performance for all demanding games from 2015 in high details and 4K resolution.

The core features are also the same as the desktop 980, so expect support for DirectX 12 (FL 12_1). There will be no support for the new H.265 video engine as found on the desktop GTX 950.

The power consumption of a single card is a lot higher than other mobile graphics cards like the GeForce GTX 980M (100 Watt TDP). According to Nvidia, the TDP of the reference design is still 165 Watt like in the desktop version. So, the TDP of the SLI combination may be as high as 330 Watt. Therefore, only big laptops with efficient cooling methods can house the GeForce GTX980 for laptops.
