最早说300是300A挑剩下的芯片，体制差很多
但也有人说二者手动超频没有什么差别
究竟能有多大差距？有没有对比评测？比如无保嘉 windforce 和 windforce oc直接对比这种？

Question: What does Non-A mean?
Answer: There are two GPU variants: TU102-300-K1-A1 (1E04) and TU102-300A-K1-A1 (1E07). Factory overclocking is prohibited on the former, it has a boost of 1545 MHz and a maximum power limit of 280W. The latter chip has varying factory overclocks and power limits up to 450 W, flashing a 300A based BIOS onto a 300 GPU and vice versa is not possible. Manual overclocking is possible on both.
Question:How big is the performance gap between the two?
Answer: Simply put, a higher power limit allows for a higher voltage, which in turn results in a higher overclock. While my 280W card could only reach 1860MHz at 0.913V, my other 330W card achieved 1980MHz at 1.018V, both at 75c running the same game in 5K resolution.
+18% power limit → +11.5% voltage → +6.5% core clock.
In further testing, trying to score as high as possible in ‘UNIGINE Superposition 1080p Extreme’ at watercooled temperatures, the 280W GPU (0.913v at 43c) got a score of 9188 (69 FPS), while the A GPU flashed to 380W (1.068V at 51c) got 10306 (77 FPS).
+36% power limit → +17% voltage → +12% performance.
At the time of writing this, the least expensive A GPU has a mere 4.4% price premium, using air cooling with a 330W power limit one can get up to 6.5% better performance, thus justifying the slight price bump. If you plan on running the card on water or with air cooling at the highest fan speed, the performance increase scales up to 12%.

10%以内的差距

EVGA丐版超频后玩游戏大概1975

区别就是前者功耗拉满boost到1.75g顶天了，后者能到1.9g+....别问我咋知道的，就是你说的那俩型号

50帧提升到63帧，45帧提升到59帧，真的没差距吗？

可能你的那个是大雕
就好比Vega 56有人可以超得比64还高，大部分人不行
