NVIDIA GeForce GTX 780M Review

The NVIDIA GeForce GTX 780M is a high-end DirectX 11-compatible best graphics card for laptops. It is based on the same chip as the GeForce GTX 680MX but offers a higher core clock at a lower TDP. It is based on the 28nm GK104 Kepler architecture similar to the GTX 680M, but features more CUDA cores (1536 vs. 1344), a higher clock rate and GPU Boost 2.0. As of summer 2013, it is the fastest laptop graphics card on the market.

As a novelty, the GeForce 700M series implements GPU Boost 2.0 to automatically overclock the core clock rate. Depending on the cooling headroom of the laptop and the application / game, up to 15 % performance gains are possible.

Overview Architecture

The Kepler architecture is the successor to the Fermi architecture that first appeared in laptops with the GeForce 400M series. The GK104 Kepler core offers eight shader blocks, called SMX, that are clocked at the same speed as the central core. In the GTX 780M, all eight blocks are active for a total of 1536 CUDA cores. Although the Kepler architecture can utilize more shader cores than a Fermi chip, its shaders can be up to twice as power efficient.  However, due to the missing hot clock of the shader domain, two shaders of a Kepler chip are of similar speed to one shader of a Fermi chip (as the latter is clocked twice as fast).

PCIe 3.0 is now supported by the mobile Kepler series and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15 percent if the laptop cooling system allows it. The implementation of this boost mode is done in the BIOS, but it is ultimately dependent upon the manufacturer of the laptop.

Key Features

Support Upto 4 Active Displays
5th Generation Pure Video Processor (VP5) Integrated
Common Codecs Are Supported Upto 4K
High Resolution Monitors Upto 3840X2160 Are Supported

Power Consumption

The power consumption of the GeForce GTX 780M should be similar or slightly higher than the GTX 680M (100 Watt TDP). According to rumors it should stay below the GTX 680MX in the iMac but still it is best suited for 17-inch desktop replacement laptops.

Technologies Supported

DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, RealtimeRaytracing and other technologies.

Memory

The GPU accesses a 4GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1250MHz.

System Suggestions

We recommend a Power Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 780M.

Game Suggestions

• TitanFall 2 (2016)
• BattleField (2016)
• World Of Warships (2015)
• BattleField Hardline (2015)
• Evolve (2015)
• Assasins Creed Unity (2014)
• Far Cry (2014)
• Call Of Duty Advanced Warfare (2014)

Well comparing laptop card drivers this card is actually pretty suitable for gaming there are a few downfalls like heat it gives out a lot of heat and without a decent cooler the card will probably wont have a long life and your laptop might even burn out but comparing it to games its actually pretty decent . I played the above mention games at high resolution and honestly it was pretty amazing experience less lags and great fps rate well I might be mistaken but I guess the 780m might be better than the desktop 780. Overall recommend this card for you guys .

Verdict

The GTX 780m has some minor flaws, but its excellent real-world performance and access to Nvidia's proprietary tech make this card a real contender in the highest tier of gaming graphics cards.
