The NVIDIA GeForce 845M is a mid-range, DirectX 11-compatible graphics card for laptops unveiled in spring 2014. It is one of the first cards based on Nvidia's new Maxwell architecture, but is still manufactured in 28 nm. In addition to a version based on GM107 (presumably partially deactivated, 128-bit, DDR3 memory), there could also be another version using the GM108 chip (64-bit, GDDR5 memory). Both models should offer approximately the same performance.GM107核心，128bitGDDR3。GM108，64bitGDDR5。提供等效性能2014年春季会出，到现在没见着鬼影

Thanks to the 128-bit memory interface (respectively the GDDR5 memory of the GM108 model), the GeForce 845M should offer a significantly higher performance than the GeForce 840M. We expect the card to be slightly in front of the old GT 750M (DDR3 version). Many games of 2013/2014 (Tomb Raider or BioShock Infinite, etc.) can be played fluently in 1366 x 768 and high detail settings. However, very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details. 比GT840m性能高，优于750md3版，768p下性能中规中矩

The power consumption of the GeForce 845M should be in a range of about 30 - 35 Watts. Therefore, the card is best suited for 14-inch laptops or larger. 功耗在30~35w内，适合14寸及以上的笔记本。在阶梯排名上略弱于660m。我就想问，这神卡特码的在哪里？为毛还没有？

特别便宜的笔记本都上860m了...

能上850m干嘛用845m

645~745~845~你们良心~厂家就坑~2G大显存怎么卖？~~~

优于gt750m d3 我怎么觉得不是这么回事呢
