一、概念上的区别
1、公版：公版显卡是指芯片厂商在发布新的GPU/VPU以后给出的参考卡型，仅能保证显示芯片性能正常发挥。
2、非公版：非公版显卡是指除公版之外，显卡厂商自行设计的PCB。

二、标准上的区别
1、公版：规定了PCB的布局、供电设计、电容选用，标准统一。
2、非公版：非公版显卡就是说其他厂家拿到公版的原始规划方案以后经过修改做出来的显卡，无统一标准。

三、材料上的区别
1、公版：公版显卡在性能稳定、自身保守(低频或不能超频)以及用料豪华。显卡芯片商为了追求品质，会选用顶级的材料以保证良好的电气性能，所以通常公版显卡的寿命普遍很高。
2、非公版：非公版显卡用料不一，高级的和低劣的都有，材质不稳定。

四、性能上的区别
1、公版：由于公版材料质量稳定，而且是由官方发布，性能整体稳定。
2、非公版：非公版材料有好有坏，鱼龙混杂，有的性能比公版好，有的不如公版。
3、非公版分为两种：一种是为了增加性能，对供电、显存等方面进行了强化，这些非公版显卡性能一般都很不错，适合高端玩家和超频爱好者。但还有一部分非公版显卡则是标准的“偷工减料”，为了降低成本而进行缩水。这些显卡价格便宜，但性能和质量远不如公版显卡。

五、上市时间的区别
1、公版：公版卡是第一时间上市的“新货”。
2、非公版：是在公版的基础上改造研究出的。

显卡公版和非公版的区别：
-
公版显卡指的是NVIDIA或ATI在新品发布之初，原厂设计(或者授权设计)的PCB版型，并指定OEM厂商生产的显卡；
-
非公版的显卡是显卡厂商对产品进行重新设计比如显存大小、散热方式、电路设计等，制造出“非公版”显卡，非公版显卡通常有自己的独到之处；
公版的优点：强悍，奢华的用料，无与伦比的稳定性，优秀的电气性能，奢华用料带来的强大超频能力，占用主板插槽少(最多双槽)，还有上市速度快；公版显卡的缺点：单风扇的封闭式涡轮散热器的效果不理想，风量不足容易出现显卡高温的情况，功能比较单一；
非公版的优点：多数比公版的便宜，默认高频，散热好，产品选择多样化，可以找到适合自己的产品，外观漂亮；非公版的缺点：做工材料较普遍，不能上通用的一体化水冷头；
公版与非公版散热器设计和其他功能设计不同。公版散热器是以静音为第一位，散热性能是排在静音后面的，非公版比较完善一键超频，双BIOS，电压跳线，水冷，刀卡版，全静音版，高频版；
公版与非公版供电部分用料的不同。公版显卡的供电部分，很少有或者没有直立的电解电容，没有体积较大的全封闭电感，往往大量采用陶瓷电容，钽电容，非公版产品在用料上多数使用了固态电容搭配普通半封尘或全封闭电感。
公版是由芯片厂家提供的标准规格元件，标准规格板型布线。
按照这种方案生产的显卡就是公版显卡。
一般情况下，高端卡基本都是公版卡；
中端卡第一批都是公版卡，以后用的多是公版PCB而元件有所调整；
至于低端卡纯公版的就更少了。
公版显卡往往在显存规格、散热器、部分元件选用的比较保守，超频性能差非公版有两种：一种是有实力的大厂自行研发的针对公版卡改良如PCB板，某些供电、显存加强以及对散热加强（这点是非公版的重点：现在的显卡法热量越来越大，公版显卡的散热器一般都很保守，导致显卡温度居高不下），以提升显卡频率，提升性能，或提高超频能力，这种非公版还是值得购买还有一种纯粹就是为了“偷工减料”，如PCB的层数，显存规格缩水，附带散热，供电缩水，
