ไม่รู้จะจริงใหมพอดีไปเจอมาก็ไปลองอ่านกันดูครับ
The AMD Radeon HD 7950 is a card based on Tahiti Pro chip, which performs around 15% worse than Tahiti XT from HD 7970 card. One of the Chinese manufacturers has released a version of 7950 with a 256 Stream processors disabled, but not permanently.
First we need to understand how are those two chips different. Tahiti Pro (HD 7950) features 1792 stream processors with 112 texture units, while Tahiti XT has 2048 stream processors and 128 texture units. Those processors are gathered in compute units, where XT version has 32 and PRO 28. Therefore, Radeon HD 7950 has 4 of them disabled. Each of those hold 64 stream processors, so 7950 lacks 256 stream processors in total. And because each of those four missing CUs also included four texture units, that specification drops from 128 to 112.
