NVIDIA GeForce GTX 960 vs Intel UHD Graphics 24EUs (Alder Lake-N) vs NVIDIA GeForce GTX 980 SLI (Laptop)

NVIDIA GeForce GTX 960

The Nvidia GeForce GTX 960 is a desktop graphics card of the upper middle class. It is based on the GM206 Maxwell chip that is produced in 28nm. The GTX960 offers 1024 shader cores, 64 TMUs and 32 ROPs (no deactivated units of the chip). The graphics memory is usually 2 or 4 GB GDDR5 (7 GHz effective clock) connected with a 128 Bit interface. 

On average the gaming performance is on a level with the AMD Radeon R9 280 and R9 285. Compared to laptop graphics cards, the 960 is slightly faster than a mobile Nvidia GeForce GTX 970M. The 970M offers more shader cores, but at a lower clock speed. The similar named GeForce GTX 960M for notebooks offers only 640 shader cores and a slightly lower core clock. The performance of the GTX 960 should be suffice for most games in full HD resolution. In our benchmarks only GTA 5 and The Witcher 3 achieved below 30 fps on average (see below for detailed benchmarks).

The GM206 supports CUDA, 3D Vision, PhysX, GeForce Experience, Surround, GameStream, GPU Boost 2.0, Adaptive Vertical Sync / G-SYNC, SLI, DSR, MFAA and Virtual Reality latency improvements. The GTX 960 also includes a H.265 capable de- and encoder as a first.

The power consumption of the GTX 960 on the desktop without load is around 10 Watt and on a similar level to the AMD counterparts. During gaming the 960 reaches around 85-100 Watt (depending on the model) which is a lot less than e.g. the Radeon R9 285 (around 170 Watt) - source tomshardware.com

Intel UHD Graphics 24EUs (Alder Lake-N)

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.
