But, as this might only be an error in GPU-Z, they tested the card in some benchmarks. Modification process in pictures (if you are interested in the whole process, which is explained step by step, visit the source link):Īs we can see this BIOS flashing modification has increased, therefore unlocked, 256 missing stream processors. According to the source, this card is also featuring 5+1 phase PWM.Ī795 has been flashed with 7970 BIOS file.
A model that we are about to present has slightly better stock clock of 880 MHz, but still worse than XT GPU.Ī rough translation suggest that this model is named A795 Fire Hurricane, but this card is not the same as reference card sold worldwide, it has better components and is also equipped with 6+8pin power connectors (just like 7970). What is also important, Radeon HD 7950 is clocked at 800 MHz (while 7970 – 925 MHz).
And because each of those four missing CUs also included four texture units, that specification drops from 128 to 112. Each of those hold 64 stream processors, so 7950 lacks 256 stream processors in total. Therefore, Radeon HD 7950 has 4 of them disabled. Those processors are gathered in compute units, where XT version has 32 and PRO 28. Tahiti Pro (HD 7950) features 1792 stream processors with 112 texture units, while Tahiti XT has 2048 stream processors and 128 texture units. One of the Chinese manufacturers has released a version of 7950 with a 256 Stream processors disabled, but not permanently.įirst we need to understand how are those two chips different. 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.
